My Downward Progress.
I had now reached the top of my engineering career; I had devoted
myself for twenty years to the development of the high-speed engine
and to the study of the best means and method of its manufacture, and
had introduced into it designs and workmanship of an excellence before
unknown in steam-engine construction. I had solved all the theoretical
problems involved in the running of high-speed engines, and, starting
from Mr. Allen’s inventions of the single eccentric link and the
four-opening balanced valve with the adjustable pressure-plate, and my
governor, had designed every constructive feature and detail of this
engine.
I had been for four years carrying on the business of the manufacture
of these engines in my own name as sole proprietor, but, as already
stated, without a cent of capital. I had in this time built between
forty and fifty engines of every size on my list, from the smallest
to the largest, except two, the 44-inch diameter cylinder having been
added after my time. Considering my business as an organization, I had
been president, secretary, treasurer, general manager, chief engineer,
inspector, and draftsman. At any rate, the duties belonging to all
those positions had been performed by me with satisfactory results. I
made every drawing, both general and detail, with my own hands, having
only the help of a young man who made my tracings, and when he had
time helped me with my section lining. At that time blue-printing had
not come into use; drawings were made on white drawing-paper and were
inked in, and the tracings were made for the shop; I began to use the
blue-print system when I removed to Philadelphia.
Every one was loyal to me, I could always rely upon my instructions
being faithfully followed, so the work ran as smoothly as the engines
themselves; we were, however, much hindered by the poor tools we had to
use. These were a fair average of American tools at that time, but Mr.
Goodfellow and myself estimated their output to average only about one
half that which we expected in our contemplated works. Besides this,
I could not establish piece-work prices or introduce any systematic
methods. I became gradually swamped with orders. These outgrew the
capacity of the Hewes & Phillips Works, or of that portion which I
could use. Before I left there, besides the four large orders already
named, amounting altogether to $48,000 f.o.b., without fly-wheels, and
which could not be handled in these works, I had accepted orders for
smaller engines sufficient to bring the aggregate up to $125,000. These
latter were more than I could manage alone, so I had arranged to have
some of these also made, or partially made, in other shops.
From this point my path sloped steeply downward to the grave of all my
hopes; in about two years and eight months the business had dwindled
to practically nothing, and I, as the party held responsible for this
result, was turned out of the Southwark Foundry into the street. At
the bottom this was entirely my own fault. No one could ask to be
associated with a better body of men than were those who united to sink
their money in the manufacture of the Porter-Allen engines.
My aim had been to reach a point where I could command the capital
necessary to establish my business according to the plan which I had
cherished ever since my return from England, but on a much larger scale
than I then contemplated. I had now reached that point. Parties who
were finding themselves enriched by my engine were ready to pour out
their money like water for my use; but there was something else that I
needed even more than their money, without which indeed, as the event
proved, their money was of no use at all. That was their respect for
me and confidence in me as a strong business man; my record would have
sufficiently justified that confidence, but of this they were ignorant.
They had no means to form a judgment of me except what I did then and
there. I never thought of this supreme requirement, and in response
to their request made them an offer which, regarded from their point
of view, appeared so unbusinesslike that they could form only one
conclusion, that while unquestionably I could make engines all right,
in matters of business I was a mere baby whose opinion on business
matters was not to be regarded seriously.
How came I to do myself, and them also, as the victims of their
mistaken judgment, this injustice? My whole life was bound up in the
engine; I cared nothing for money except to develop its manufacture;
I felt that every dollar paid to myself would leave so much less for
this purpose. I asked nothing for the good-will of my business, for I
was not selling it; they were putting money into my business, which,
of course, I would continue to carry on as I had done. This was my
mistaken view. I consulted fully with Mr. Hope, whose interest was
equal with mine, and he viewed the matter precisely as I did. Although
standing at the head of his profession as a fire underwriter, he had
not the special business training or experience that would enable him
to give me the advice I needed, so I told them that if a company should
be formed to manufacture the engines with $800,000 capital, I would
assign to it my patents for $100,000 of its stock, the value of which
I assumed I would increase several fold in a few years. Beyond this I
assumed everything and made sure of nothing, so our minds never came
together. I did not assert myself because it never occurred to me that
I needed to do so.
They could not understand my position. They could not appreciate
my sentiment. They were business men, and did business on strictly
business principles. What their position was I came to understand
later. From the fact that I did not stipulate for it they concluded
that I did not expect the presidency of the company, but had yielded it
to them, which they accepted, of course, in accordance with the general
usage that capital takes the direction of a business which it knows
nothing about, relying upon skilled experts in its various departments.
Thus by my failure to realize their necessary position and to lay
before them a thoroughly business-like proposition, demanding for
myself the practical direction of the business and a proper sum for the
patents and the good-will of the business, and assuring to them the
safety and disposition of their money the enterprise was doomed from
the start.
An excellent opportunity seemed to offer itself for going right on with
my business without the delay which would be involved in the erection
of new works. The Southwark Foundry was in the market for sale. These
were the old engineering works of the firm of S. V. Merrick & Sons;
they were famous works before the war, when they were largely devoted
to the manufacture of municipal gas and water plants, having, I think,
a monopoly of this class of work, for which they were especially
equipped. During the war they had built engines for some government
vessels. A few years after the war the elder Mr. Merrick died, and his
two sons, J. Vaughan and William H. Merrick, retired from business,
and these works were closed. In company with several of the gentlemen
interested I was shown over the works by William H. Merrick and was
very favorably impressed with them. They covered a large plot of
ground, the front extending from Fourth to Fifth streets on the south
side of Washington Avenue, in Philadelphia; they were favorably located
with respect to transportation facilities, a branch of the Philadelphia
and Baltimore Railroad ran through this avenue to the Delaware River,
and two switches from these tracks entered the works, one going to the
foundry and one to the erecting-floor. This floor was commanded by
three cranes, operated by power, the largest I had ever seen, while
an annex to the foundry was commanded by a steam-crane of equal size,
and the main foundry floor was provided with an overhead traveler, the
only one at that time in the country. The machine-shop was a large
three-story building, the first and second floors of which, as well
as the erecting-shop, were filled with tools, some of them of large
size. I was particularly impressed by the great planer, the largest in
the country, capable of passing objects twelve feet square. The office
was provided with a large fire-proof vault which was carried up to the
second story for the use of the drawing-office.
I expressed myself decidedly in favor of purchasing these works. I
could form no judgment respecting the tools, all their working parts
being coated with a composition of white lead and tallow; but I did not
care much about them, because I should speedily fill the works with the
latest improved tools, most of which I expected to import from England.
A contract was immediately made for the purchase of these works, in
part payment for which the Merrick brothers were to accept stock in the
proposed company. Thus they became numbered among our stockholders.
I was next invited to attend a meeting of a few gentlemen held at the
office of the Cambria Company to arrange a slate for the action of the
subscribers at a meeting which had been called for organization. This
first meeting was full of surprises to me. I went into it expecting the
gentlemen to say to me: “Of course, Mr. Porter, you will accept the
office of president?” quite unconscious that I had made it impossible
for them to think of such a thing, but quite conscious that no amateur
in that position could by any possibility make the business successful,
unless he should commit the management entirely to my hands and content
himself with being a mere figurehead.
Mr. Townsend, the president of the Cambria Company and the leading
mover in this enterprise, called the meeting to order and announced
that the first question to be settled would be the name of the company.
I remarked: “There can be but one name for it: the Porter-Allen
Steam-engine Manufacturing Company.” Then Mr. William H. Merrick spoke
up: “I don’t know about that; of course, no one can imagine that the
manufacture of these engines can employ all the resources of these
great works; there is a vast amount of work of the character formerly
carried on in them which will naturally flow back to them, and I think
the door should be left open for its return.” I expressed my amazement
at such a view; I had not come there to revive any old business, but to
make the Porter-Allen engine and nothing else; that it must be obvious
to any observer that my business only required suitable means for
carrying it on to grow to great proportions, and the resources of these
works, whatever they were, would need to be greatly enlarged for its
use, and besides the name ought to describe and advertise the business.
When a vote was taken every man voted for the historic Philadelphia
name of the “Southwark Foundry,” to which they added “and Machine
Company,” and I discovered that my views had no weight at all. I had
afterwards the pleasure of being asked by my friends occasionally what
good I supposed that name would do my business.
The next subject was the selection of a president, and my next
discovery was that I was not even thought of. If any one had been asked
why he had not thought of me he would, from his point of view, very
properly have replied that “to commit the interests of this company to
a man who had shown so little ability to look out for his own interests
did not impress him favorably.” Every vote was cast for William H.
Merrick, and I was selected as vice-president, with charge of the
manufacturing.
A day or two after, the meeting was held which had been called for the
purpose of hearing the report of the patent expert and organizing the
company. At this meeting the expert was not prepared to report, as an
application for the reissue of an important patent was still pending.
Mr. Merrick moved that a temporary organization be then effected, so
that we might proceed at once with work on pressing orders. On my
assurance that this reissue was certain to be allowed, the motion was
adopted and a temporary board of directors was elected. Mr. Merrick
and myself were elected president and vice-president respectively. Mr.
Merrick told me afterwards that he made the motion because he knew that
those twenty-one gentlemen there assembled could never be got together
again if this meeting should prove fruitless.
The directors held a meeting immediately after, and at this meeting I
presented a letter which I had written to the chairman of the meeting
called for organization, setting forth the requirements of the engine
for the latest and most improved tools and asking for an immediate
appropriation of $100,000 for their purchase, as time was of the utmost
consequence. To this Mr. Merrick replied that such action would be
entirely unnecessary, saying: “I assure you gentlemen, and I assure
Mr. Porter, that for a long time to come he will find in these works
everything he can possibly desire.” Of course I could make no reply to
this positive statement, and the matter was dropped. We immediately
took possession of the works, and a large force of men were put at
work cleaning the tools and getting them in working order; I also had
my drawings, patterns, and all work in progress brought from Newark
and from all shops where it had been commenced. Prominent among these
latter were the bed, cylinder and shaft of the first of the 40×48-inch
engines which were then ready for finishing.
In about two weeks from the date of this meeting Mr. Goodfellow came
into the office pale and trembling with excitement, and addressing
himself to me, Mr. Merrick sitting on the opposite side of the table,
said: “Mr. Porter, I give it up; we might just as well be set down
in a cotton-mill to make steam-engines; there is not a tool in the
place that has not spoiled every job that has been put in it, from the
day we came here. I don’t believe another such lot of antiquated and
worn-out rubbish exists on the face of the earth.” This was not news
to me, as I had spent much of my time in the shop. Our most serious
disappointment was the condition of their great planer; we had hurried
the above-mentioned engine bed on it as soon as it arrived, and when
it had been planed the surface plate was laid on the guide-bars, which
were 7 feet 6 inches long, and it was found to rock on two diagonal
corners more than an eighth of an inch, showing a cross-wind of over
half an inch in the whole length of the planer bed; this of course
rendered the tool useless in its present condition. I had found that
the means for boring the 40-inch cylinder and for finishing the shaft,
as well as for doing the other work for this engine, were all equally
useless, and I proposed to Mr. Merrick that these parts should all be
sent back to the shops from which they had been brought and finished
there, and the engine altogether built in outside shops, just as I had
built the first one. This he flatly refused to do, saying he would not
make such an exposure of our condition. Our plight may be understood
when I state that it was over a year before we could deliver that
first large engine, although every effort was made to complete it, the
castings and forgings waiting for many months.
“But,” exclaims the reader, “why, when this state of affairs was
first discovered, were not steps instantly taken to remedy it?” The
answer to this question involves a very different subject. When I had
received in Newark a letter from Mr. Merrick requesting me to send on
my patents for examination by an expert, I was suddenly reminded that
I had omitted to obtain the reissue of the latest patent which Mr.
Allen had obtained, namely, the one for his adjustable pressure-plate,
which had been so shockingly muddled by the Washington agent of the
patent solicitors that when we received it we could not understand the
specification, and the claims were absolutely meaningless. However, I
had said to myself, there will be time enough to have it reissued when
it becomes necessary, as applications for reissue are always passed
upon immediately. But before sending the patents on, I prepared myself
a new and clear specification for that patent and put it in my pocket.
In two or three days I followed the patents to Philadelphia and met
the patent solicitor; he told me all the patents seemed to be well
enough except this one, and this he could make nothing out of. I told
him how that came to be such a muddle, that I always intended to get
it reissued and now would employ him to do it. I produced the amended
specification I had prepared for that reissue; he read it and handed it
back to me, saying it would be of no use to him. I instantly thought of
the protest of Mr. Perker: “Really, Mr. Pickwick, really, my dear sir,
when one places a matter in the hands of a professional man he must not
be interfered with; indeed, he must not, my dear sir, really.” I made
an humble apology for my presumption, but asked him if he would get
the application in the next day at farthest, that the reissue might be
received in time for him to report on it at the meeting called for the
organization of the company, then some days distant. He made no reply.
I soon found that I had fallen into the hands of a traitor who intended
to use his professional power to strangle my enterprise in its birth,
and who never did give up his prey until it was torn from his fangs.
Not hearing from him for a day or two, I called to see what was the
matter, and was stunned by his telling me that he had determined not
to apply for a reissue, but to report against me on the patent as it
stood, saying that a reissue could not be got, and if it was it would
be good for nothing. I attempted to argue the matter with him, but
found him firm. I then went directly to the office of Morgan & Lewis,
the attorneys for the company, and told the story. Mr. Morgan said, “I
will go and see him at once;” so we went together. The expert repeated
his determination to Mr. Morgan, and, anxious that the latter should
understand the merits of the case, I presented it to the expert as
plainly as I knew how, Mr. Morgan being an attentive listener. Many
months afterwards I realized the vital importance of the lesson I then
gave to Mr. Morgan. The expert persisted in his determination, but
consented to see Mr. Morgan again the next day. On our way back I said
to Mr. Morgan: “It seems to me that this man does not see the point of
the application because he won’t see it; he doesn’t want to see it.”
Mr. Morgan made the rather enigmatical reply: “It seems very plain to
me.”
The next day Mr. Morgan made the point to the expert that he could not
afford to take such a position as that--he could not sustain it. He
then consented to make the application, but added what he had already
said to me, that he had no idea it would be granted, and if it was,
it would be good for nothing. It will hardly be credited that he was
over two months in preparing this application, getting it into a form
in which he was sure it could not be allowed. When it was finally
shown to me I could not understand it. It contained two references,
the pertinence of which I could not see; he assured me, however, that
it was the very best that could be done, although he said he had very
little hopes that it would be allowed. Sure enough, in a few days the
rejection was received from Washington and a meeting was called to
hear his report. He used very strong language in making this report,
saying: “This rejection is final and the case is hopeless,” and walking
over to where I was sitting, he shook a paper in my face with an air
as if I had been a detected felon and he held in his hand the proof
of my rascality, saying: “This is a paper I received from Washington
this morning that settles your hash, sir.” When he sat down the silence
might have been felt. Every one shrank from what appeared to them the
inevitable and final step, the adoption of a resolution to the effect:
“Whereas Mr. Porter has failed to keep his agreement with us, the whole
matter be now dismissed from our further consideration.”
I did not allow them much time for reflection, but rose and made a
little speech as follows: “Mr. Chairman, I have but a single word to
say. I have taken this case out of the expert’s hands; I expect to
go to Washington to-morrow morning and return in the afternoon, and
when I come back I shall bring this reissue with me.” No one said a
word, but I knew what was in every man’s mind: “What a fool, when our
great Philadelphian authority has spoken, to imagine that _he_ can do
anything to change the result!” However, there was no disposition to
cut me off by any precipitate action, and the meeting adjourned subject
to the call of the chair, every one feeling that it was a mere waste of
time.
The next morning I was received by Mr. Fowler, the accomplished
chief examiner in the class of steam-engines, with his usual extreme
courtesy. He told me that he felt very sorry at finding himself
obliged to reject my application, but the very precedents cited in
the application itself left him no alternative. “However,” he added,
“if you have anything new to present I shall be most happy to receive
it.” In reply I handed to him the specification which had already
done duty so ineffectively with the expert and in which I had not
changed a syllable. He read it through with fixed attention, and the
instant he finished he exclaimed: “Why, Mr. Porter, it is perfectly
obvious that you are entitled to this reissue, and the cases cited
in the application have nothing to do with it; but why was not this
presented to me in the first place?” I told him I had prepared it for
that purpose and placed it in the hands of the expert, who, after
reading it, returned it to me, saying it would be of no use to him.
Mr. Fowler instantly asked me if I had prepared any claims. I told him
I had, because I could not get any one to prepare them for me; but it
was a new business to me, and I had asked the advice of the expert
about them, who, after reading them, returned them to me without any
suggestion, merely remarking: “If you get these allowed you will be
doing very well.” The moment Mr. Fowler glanced at them he exclaimed:
“Oh, Mr. Porter, we cannot allow any such claims as these; they are
functional claims, which the Patent Office never allows.” Then,
evidently seeing my helpless condition in the hands of a traitor, he
instantly added: “I shall be occupied this morning, but if you will
call at three o’clock I will have two claims prepared for you which
will be allowed.” So the expert had let me go to Washington with claims
that he knew could not be allowed, and sure that my errand would be
fruitless. But he did not imagine that the examiner would see through
his treachery and thwart it. At three o’clock our interview was brief;
as I entered Mr. Fowler’s room he handed me a paper, saying: “These
have been allowed; you will receive the reissue in the course of
three or four days, and it will appear in next week’s _Gazette_. Good
afternoon.”
I suppose that I never looked on a countenance expressing more
amazement than did that of Mr. Merrick when next morning I handed
him the copy of the claims and told him my brief story. He said he
could hardly believe his senses. Taking the paper, he started for Mr.
Townsend’s office, and in the course of an hour all the parties in
interest had been apprised of my easy triumph. The reissue arrived as
promised, was placed in the expert’s hands, and a meeting was called
to receive his report. I thought my troubles were all over; the case
was an absolutely simple one, there was no pretense that the invention
was not new, and he _must_ report in its favor, no matter how reluctant
he might be to do so. What was my amazement and fury when he quietly
stated to the meeting that he had no report to make; that the case
involved very serious questions which would require much time for their
consideration; that the granting of the patent was nothing--it was the
business of the Patent Office to grant patents, not to refuse them,
but whether or not they would be sustained by the courts was entirely
another matter, about which in this case he had very grave doubts.
I now did what I never did before or since, and what no good business
man, who is accustomed to accomplish his purposes, ever allows himself
to do: I, who always prided myself on being destitute of such a thing,
lost my temper. And not only my temper, but, like Tam O’Shanter, I
lost my reason altogether. Already driven frantic by the frightful
condition of affairs at the works, which had been protracted over three
months by this man’s machinations, and which he threatened to continue
indefinitely while he should endeavor to find some means to accomplish
his purpose of wrecking my business, without an instant for reflection
I shouted, regardless of all proprieties: “You rascal! What was the
Patent Office doing a week ago when you reported to these gentlemen
that this reissue had been refused, that the decision was final and
the case was hopeless; what were they doing then, I would like to
know? Were they granting patents or refusing them? The fact is, you
are either a traitor or know nothing about your business, and you may
hang on either horn of the dilemma you like,” and I sat down, having
in these few seconds done myself and my case more harm than anybody
else could have done in a lifetime. I did not reflect that I could not
have the sympathy of my audience; they knew nothing of the state of
affairs at the works--this they had been kept in ignorance of,--nor of
the consistent course of treachery which this man had been following.
All they could see was that I had used outrageous language, for which
they could not imagine any justification, toward an eminent patent
lawyer who enjoyed their confidence, and they naturally supposed that
was my usual way of doing business. The chairman coldly informed me
that the lawyer was their patent adviser and nothing whatever could be
done until his report on the reissue should be received. I had entered
the room expecting to receive the congratulations of every one on the
bold coup by which I had saved my business. I left it unnoticed by any
one. The reader will not be much surprised to learn that it was months
before we heard from him again--months more of frantic helplessness.
About the first of August I called at the expert’s office and was
informed that he had gone on his vacation and would be absent about
six weeks, and the case could not be taken up until his return. In my
desperation I called upon Mr. Townsend and made to him a clean breast
of our helpless condition, and offered to pledge all our stock as
security for a loan of the money necessary to buy a few of the most
indispensable tools. He replied to me: “Suppose the report of the
expert shall be adverse and the enterprise be abandoned, what do you
think your security will be worth?”
I succeeded in saving one order from the wreck in rather a singular
manner. This was an order from Mr. Lewis, of Cincinnati, the projector
of the cottonseed-oil business, for an 18×30-inch engine to drive
the machinery of their first oil-mill at Houston, Texas. I had built
in Newark an engine of the same size for Senator Jones of Nevada, to
drive an ice-making plant which he was establishing in the city of New
Orleans. Word came to me sometime that spring that this enterprise had
proved a failure, the work had been abandoned, and the engine, their
only asset of value, was for sale. I instantly bought it and sent a man
down to transport it to Houston and erect it there. Mr. Lewis wrote me
from Cincinnati an indignant letter at my sending him a second-hand
engine. I replied to him, stating first it was my only possible way
of filling his order at all, as I did not know when we should be
able to build an engine in our new works, and, second, that it was
a new engine, having been run only a few weeks, long enough to show
its excellent condition and not so long as engines are often run in
public exhibitions, from which they are always sold as new. Mr. Lewis
gracefully accepted my explanation, and the engine was in readiness
for them to grind the coming cottonseed crop. The next summer we had
a call from the agent of that mill, who had come North during their
idle interval, while they were waiting for their next crop, to make his
report at Cincinnati, and had come out of his way to tell us of the
wonderful manner in which that engine had carried them through their
first season, which he concluded by saying: “That is the engine for
the cottonseed-oil business.” After he had gone I said to Mr. Merrick:
“That is an old story to me; everybody says that is the engine for
their business, whatever their business may happen to be.”
What did I do with myself during that six months? Well, I was not
altogether idle. First I found all the drawers in the drawing-office
filled with piles of old drawings which Mr. Merrick ordered to be
preserved and which we piled up on the floor of the unoccupied third
story. Out of the contemplation of that confused heap I evolved a new
system of making and keeping mechanical drawings, which I described in
the following paper, read the next year before the American Society of
Mechanical Engineers:
“The system of making and keeping drawings now in use at the works of
the Southwark Foundry and Machine Company in Philadelphia has been
found so satisfactory in its operation that it seems worthy of being
communicated to the profession.
“The method in common use is to devote a separate drawer to the
drawings of each machine or each group or class of machines. The idea
of this system is keeping together all drawings relating to the same
subject-matter. Every draftsman is acquainted with its practical
working. It is necessary to make the drawing of a machine and of its
separate parts on sheets of different sizes. The drawer in which all
these are kept must be large enough to accommodate the largest sheets.
The smaller ones cannot be located in the drawer, and as these find
their way to one side or to the back, and several of the smallest lie
side by side in one course, any arrangement of the sheets in the drawer
is out of the question.
“The operation of finding a drawing consists in turning the contents
of the drawer all up until it is discovered. In this way the smaller
sheets get out of sight or doubled up, and the larger ones are torn. No
amount of care can prevent confusion.
“In the system now proposed the idea of keeping together drawings
relating to the same machine, or of classifying them according to
subjects in any way, is abandoned, and in place of it is substituted
the plan of keeping together all drawings that are made on sheets of
the same size, without regard to the subject of them. Nine sizes of
sheets were settled upon as sufficient to meet our requirements, and
on a sheet that will trim to one of these sizes every drawing must be
made. They are distinguished by the first nine letters of the alphabet.
Size A is the antiquarian sheet trimmed, and the smaller sizes will cut
from this sheet, without waste, as follows:
“A, 51″×30″; B, 37″×30″; C, 25″×30″; D, 17″×30″; E, 12¹⁄₂″×30″; F,
8¹⁄₂″×30″; G, 17″×15″; H, 8¹⁄₂″×15″; I, 14″×25″.
“The drawers for the different sizes are made 1 inch longer and wider
than the sheets they are to contain, and are lettered as above. The
drawers of the same size are distinguished by a numeral prefixed to the
letter. The back part of each drawer is covered for a width of from
6 to 10 inches, to prevent drawings, and especially tracings, from
slipping over at the back.
“The introduction of the blue-printing process has revolutionized the
drawing-office. Our drawings now are studies, left in pencil. When
we can find nothing more to alter, tracings are made on cloth. These
become our originals and are kept in a fire-proof vault. _This system
is found admirably adapted to the plan of making a separate drawing for
each piece._ The whole combined drawing is not generally traced, but
the separate pieces are picked out from it. _All our working drawings
are blue-prints of separate pieces._
“Each drawer contains fifty tracings. They are 2¹⁄₂ inches deep, which
is enough to hold several times as many, but this number is all that is
convenient to keep together. Each drawing is marked in stencil on the
margin in the lower right-hand corner, and also with inverted plates
in the upper left-hand corner, with the letter of the drawer and the
number of the drawing, as, for example, 3F-31; so that whichever way
the sheet is put in the drawer, this appears at the front right-hand
corner. The drawings in each drawer are numbered separately, fifty
being thus the highest number used.
“For reference we depend on our indices. Each tracing when completed is
entered under its letter in the numerical index, and is given the next
consecutive number. From this index the title and the number are copied
into other indices, under as many different headings as possible.
Thus all the drawings of any engine, or tool, or machine whatever,
become assembled in the index by their titles under the heading of
such particular engine or tool or machine. So also the drawings of any
particular piece, of all sizes and styles, become assembled by their
titles under the name of such piece. However numerous the drawings,
and however great the variety of their subjects, the location of any
one is, by this means, found as readily as a word in a dictionary. The
stencil marks copy, of course, on the blue-prints, and these, when not
in use, are kept in the same manner as the tracings, except that only
twenty-five are placed in one drawer.
“We employ printed classified lists of the separate pieces constituting
every steam-engine, the manufacture of which is the sole business of
these works, and on these, against the name of every piece, is given
the drawer and number of the drawing on which it is represented. The
office copies of these lists afford an additional mode of reference,
and a very convenient one, used in practice almost exclusively. The
foreman sends for the prints by the stencil marks, and these are thus
got directly without reference to any index. They are charged in the
same way, and reference to the numerical index gives the title of any
missing print.
“We find the different sizes to be used quite unequally. The method
of making a separate tracing of each piece, which we carry to a great
extent, causes the smaller sizes to multiply quite rapidly. We are
also marking our patterns with the stencil of the drawings, as well as
gauges, templets, and jigs.
“It is found best to permit the sheets to be put away by one person
only, who also writes up the indices, which are kept in the fire-proof
vault.
“We have ourselves been surprised at the saving of room which this
system has effected. Probably less than one fourth the space is
occupied that the same drawings would require if classified according
to subjects. The system is completely elastic. Work of the most diverse
character might be undertaken every day, and the drawings of each
article would find places ready to receive them.”
It will be observed that in planning the sizes of sheets I was limited
to antiquarian paper. Now no limitation exists. I should to-day
increase the number of sizes.
The whole summer passed, many had taken trips to Europe and back, when
about the middle of September Mr. Morgan notified the chairman that he
had received the expert’s report and requested him to call a meeting of
the subscribers to hear it. I went to the meeting with mingled hope and
apprehension. Mr. Morgan read a long letter from the expert containing
an elaborate argument against the patent which he concluded by saying
that he could not recommend its acceptance. When Mr. Morgan had
finished reading the letter he continued: “Mr. Chairman, I am tired of
this man’s delays and quibbling, and I now advise you that Mr. Porter
has performed his contract, and it only remains for you to perform
yours.” This was the harvest from the seed I had sown six months before.
The following is the Reissue on which the patent expert hung up our
business for six months. The specification was written by me, the
disclaimer and claims were written by Chief Examiner Fowler.

_Balanced Valve._
SPECIFICATION forming part of Reissued Letters Patent No. 9303, dated
July 20, 1880.
Original No. 167865, dated September 21, 1875. Application for
reissue filed June 2, 1880.
_To all whom it may concern:_
Be it known that I, JOHN F. ALLEN, formerly of the city, county,
and State of New York, but now of Brooklyn, New York, have invented
certain new and useful Improvements in Balanced Slide Valves, of
which improvements the following is a specification.
My invention relates to that class of balanced slide-valves in which
the valve is practically relieved from the pressure of the steam,
this pressure being sustained by a plate supported above the valve,
but so nearly in contact with it that the space between them will not
admit steam enough to affect the valve. Such plates are designated as
“pressure” plates, and have been made in some instances adjustable,
in order that they may be closed up to the valve as the faces of the
valve and its seat become worn. Heretofore such adjustments have been
affected by different mechanical devices, among which there was, in
one instance, a spring to move the plate laterally or crosswise of
the valve while the pressure of the steam held the plate down; and in
other instances screws were used to move the plate in two directions,
both in line with the movement of the valve, and to hold the plate in
its adjusted position. All of these devices, however, are liable to
objections well understood by engineers.
It is the object of my invention to obviate these objections in
a balanced slide-valve; and to this end my improvements consist
in utilizing the pressure of the steam for giving motion to the
pressure-plate down inclined supports and toward the valve; in
employing supports inclined to the face of the valve at a steep
angle, considerably exceeding the angle of repose of the metal,
so that the pressure of the steam on the upper surface of the
pressure-plate may be relied on for giving to it the above-described
motion, and in employing an adjustable stop to prevent the pressure
of the steam from forcing the pressure-plate into too close contact
with the valve.
In the accompanying drawings, which form part of this specification,
Figure 1 is a transverse section through a steam-chest in which my
improved balanced slide-valve is applied, the section being on the
line _x x_ of Fig. 2, and Fig. 2 is a longitudinal section on the
line _y y_ of Fig. 1.
[Illustration]
[Illustration]
The valve A is fitted upon its seat in the steam-chest B, and moved
to and fro over the ports in the usual manner. The back of the valve
is a plane surface, parallel with its face. Along the sides of the
steam-chest I provide two parallel guides--one, _b_, inclined
downward and outward, and the other, _b¹_, inclined upward and
outward, as shown in Fig. 1, from a point in the same plane with
the back of the valve and at an angle considerably greater than the
angle of repose of the metal. Theoretically, the plate should move
down its inclined supports if the angle of inclination exceeds at
all the angle of repose; but practically, under conditions, often
unfavorable, existing in the steam-chest to render the action
certain, this angle should be largely in excess, as shown in the
model and drawings. In the instance shown I have provided chambers G
at the ends of the steam-chest, through which the steam may pass over
the ends of the pressure-plate to the ports; but any other approved
passage for the steam may be provided.
The pressure-plate C fits snugly in the steam-chest lengthwise, and
moves freely in it crosswise. This plate has an opening in the top
and a hollow center, so that the steam entering at the top passes
through the center and into the chambers G, at the ends of the
steam-chest. The bottom of this plate has a plane surface, parallel
with the back of the valve A, and beyond this plane surface it has
lateral inclines _c c¹_, parallel with the lateral inclines _b b¹_
on the sides of the steam-chest, so that when the plate is in place
its lateral inclines rest upon and fit closely to the inclines on the
chest, thus supporting the plane surface of the bottom of the plate
close to the top of the valve.
The width of the plate being less than that of the chest B, it will
be seen that the plate in this position would have a certain range of
movement upon the inclines crosswise of the steam-chest.
A screw-stop, H, passes through the steam-chest, and bears upon the
adjacent side of the pressure-plate, which will still be free to be
moved crosswise of the valve.
The operation is as follows: The stop H being adjusted to the point
at which it is desired to maintain the pressure-plate, the pressure
of the steam will act upon the plate and tend to force it down the
inclines _b b¹_ crosswise of the valve and against the stop, which
will thus determine the range of movement of the plate and the
relation between its plane surface and the back of the valve. At the
same time the stop, being entirely independent of or disconnected
from the plate, can be readjusted as required to compensate for
any wear upon the surfaces of the valve or its seat, and the steam
will at all times maintain the plate at the point determined by the
adjustment of the stop. This adjustment is, of course, made without
opening the steam-chest.
I do not claim the employment of inclined supports by a movement
along which the pressure-plate is caused to approach or to recede
from the valve, since this device has been already the subject of
patent; but
I claim as my own invention and desire to secure by Letters Patent--
1. A balance-valve provided with a pressure-plate acted upon by
steam-pressure and having a downward and lateral movement through
means of steep inclines, as shown, as and for the purpose set forth.
2. A balance-valve provided with a pressure-plate reposing upon steep
inclines, as shown, and suitable means for limiting its movement upon
the inclines, the said plate being held down by steam-pressure, as
and for the purpose set forth.

Witnesses:
DE WITT BOGARDUS,
J. W. DURBROW.
Mr. Morgan’s advice was received by the meeting with a feeling of
relief from a long suspense; it was at once accepted unanimously,
and the temporary organization was made permanent. The directors
immediately convened. Before proceeding to the transaction of business
one of the directors said to me: “Mr. Porter, you have now been in the
Southwark Foundry for six months, and I understand that not a single
engine has been sent out from that place in all that time; will you
tell us why this is so?” I had then an opportunity of witnessing a
nobility of soul such as few persons meet with in the whole course of
their lives. Mr. Merrick rose and said: “I will save Mr. Porter the
trouble of answering that question. Mr. Porter has not sent a single
engine out of these works because he has not had a single tool with
which he could make an engine. I thought I knew all about those tools
when, last March, I assured you and Mr. Porter he would find everything
he could possibly desire, when the fact was I knew nothing about them.
I have been through those tools carefully with Mr. Goodfellow and
have seen for myself that not one of them could produce work fit to
be put in these engines. While I am about it I wish to make another
confession: I said then, and you all agreed with me, that it could not
be expected that the manufacture of these engines could employ all the
resources of that great establishment, and so we left the door open for
the return to it of the class of work which had formerly occupied it;
but from what I have myself seen in the six months I have been there
I am able to say to you that if the works had possessed the resources
which I really believed they did possess, these would have been
insufficient to meet the demand for these engines which has come to us
from all parts of the country and for many different kinds of business.
Mr. Porter knew what he wanted and the demand that might reasonably be
expected; I had no conception of the one or the other. It is a great
pity that we did not then give him the means he asked for, and I hope
this will be done now.”
Mr. Henry Lewis spoke up and said: “What did Mr. Porter ask for? I
have no recollection of his asking us for anything at all.” None of
the directors could remember anything about it; the letter which I had
addressed to the chairman had even disappeared. Luckily, however, I
had made a copy of it, and I produced the letter-book, in which it was
the first letter copied, and read them this copy. I should say here
that I have inquired at the works for this letter-book, but have been
told by Mr. Brooks, the president, that all correspondence more than
twenty years old having no legal value had been destroyed. When I had
finished, Mr. Lewis exclaimed: “Did you write that letter?” “I did,
sir,” I replied. “Well,” he said, “I suppose I must have heard it, but
I have not the faintest recollection of it.” All said the same thing
except Mr. Merrick, as it had brought out his reply.
This illustrates the indifference of the directors at that time to
anything that came from me. An earnest disposition was now manifested
to make all the amends possible; the $100,000 which I had asked for was
immediately appropriated. In view of the utter barrenness of the works
I was asked if it had not better be made $200,000, but this I did not
favor. I told them I would rather proceed more slowly, especially as
many of the old tools might be made serviceable when we should have
perfect tools with which to refit them. So at last I had triumphed at
every point, but at what a cost, O, what a cost!
With a number of other engineers I attended, by invitation, a meeting
held at the office of the _American Machinist_, February 16, 1880,
which determined upon the organization of the American Society of
Mechanical Engineers, and soon after I had the honor of being invited
to read a paper at the first regular meeting of this society, held in
the auditorium of the Stevens Institute at Hoboken, N. J., on the 7th
of April following. The date of this meeting, it will be observed, fell
during the time when the Philadelphia expert was racking his brains to
concoct for me an application for a patent reissue which he felt sure
could not be allowed.
I read the following paper:
“This association can vindicate its right to exist only by exerting
a constant beneficial influence upon engineering practice in all its
departments. At the outset of its career it should take a progressive
attitude, planting itself upon sound principles of construction, aiming
to inspire the engineers of our country with the highest conception of
mechanical truth, and to diffuse a correct understanding of the means
and methods by which this truth is to be attained.
“As one subject of primary importance, I wish to present that of
strength in machine tools. Truth of construction, facility of
operation, and range of application are all, in one sense, subordinate
to this fundamental quality of strength; for they are in a greater or
less degree impaired where adequate strength is not provided.
“But what _is_ adequate strength? On this point there exists among the
makers and users of tools a wide diversity of opinion. On examination
it will be found that this diversity coincides with the diversity in
mechanical sensibility. As the mechanical sense is developed, there
arises in just the same degree the demand for greater strength in
machine tools.
“To the mechanic who has never formed a notion of a division of an inch
more exact than ‘a bare 32d,’ one tool, if it can in any way be kept
from chattering, is as good as another, and better if it is cheaper.
“To those, on the other hand, who demand in every piece, as it comes
from the tool, the closest approach to perfection, both in form and
finish, a degree of strength in the tool appears, and is demonstrated,
to be indispensable that to the former class seems as absurd as the
results attained by means of it appear incredible.
“In this country, as indeed all over the world, the standard of
mechanical truth has been very low. It is here, however, as everywhere,
rapidly rising. The multitude are being educated up to the standard
of the few. In this work members of this association have borne and
now bear an honorable part. Just in the degree that the standard of
mechanical excellence is raised must the demand become more general for
greater strength in machine tools, as indispensable to its attainment.
“But what is the standard of strength? The anvil affords perhaps its
best illustration. It is a strength enormously beyond that which
prevents a tendency to chatter, a strength that under even the heaviest
labor prevents the least vibration of any part of the tool, or any
indication of effort more than if the object being cut were a mass of
butter.
“It will be seen that this absolute solidity in machine tools, while
truth cannot be attained without it, enables also mechanical operations
generally to be performed with far greater expedition, and the
subsequent work of the finisher to be in any case much diminished and
often dispensed with entirely.
“We are enabled in most cases to come at once to the form desired,
whatever may be the quantity of material to be removed, and always
to finish the surface with a degree of truth and polish otherwise
unattainable, dispensing in a great measure with the use of that
abomination, the file.
“Now, with this standard in our minds we look over the face of the land
and behold it covered with rubbish.
“It is curious to observe how ingenious toolmakers have generally been
in trying to avoid this quality of strength, and how deceptive an
appearance in this respect many tools present.
“It is interesting also to note how little this quality of solidity
adds to the cost of castings. The addition is merely so much more
pig-iron and really not that, because in the stove-plate style the
forms are more complicated, the patterns more expensive and frail, and
the cost of molding is greater. But what signifies even a considerable
increase in the first cost of a tool that in daily use is to perform
the work of many and is to place its possessor on a mechanical eminence?
“It is not the purpose of this paper to enter into details,
interesting and important as these are, but to draw attention to the
subject in a general way. The improvement observed quite recently in
this respect, as well as in other points of tool construction, is
highly gratifying and encourages the expectation of still further and
more general progress.”
The following summer I employed some of my leisure time in making the
plans for a couple of machine tools. One of these was a double-drilling
machine for boring the boxes of connecting-rods, there being then
no such machine in existence to my knowledge. I had been planning
such a machine in my mind as long ago as when I was in the works of
Ormerod, Grierson & Co., in Manchester, England, in 1864-5. This
tool was designed first to bore the two boxes simultaneously and
rapidly, and, secondly, to bore them with absolute accuracy in their
distance apart and in the intersection by their axes of the axis
of the rod at right angles in the same plane, and all this without
measurement or setting out or the possibility of error. The other tool
was comparatively a small affair. I utilized an old milling-machine
for facing simultaneously the opposite sides of nuts and taking the
roughing and finishing cuts at the same time. The ends of the nuts were
first faced on a special mandrel which insured their being normal to
the axis of the thread. A string of these nuts was then threaded on a
mandrel fitting the top of their threads and some 15 or 18 inches long,
on which they were held against a hardened collar, the diameter of
which was equal to the distance between their opposite finished faces.
The cutting tools were set in two disks about 12 inches in diameter;
they were set about an inch apart alternately in two circles, one about
one eighth of an inch inside the other, and were held in position by
set-screws in the periphery. The cutters in the outer circles did the
roughing; those in the inner circles were set projecting about 0.001
of an inch beyond the roughing tools and finished the surfaces. The
mandrel was set between centers, and the string of nuts was supported
from the table at the middle of its length. The nuts were secured in
position by a dividing plate on the forward center-bearing. What was
done with the two drawings I will state presently.
My success, as already related, came so swiftly and completely after
six months of anxiety as to be almost overwhelming. The more I thought
about it the more ecstatic I became; all my disasters had been of a
nature the effect of which time would soon efface. I was full of high
anticipations, I could see no cloud in the sky; I awakened to my old
zeal and energy and set myself eagerly to the work of providing new
equipment, unable to realize the real helplessness of my position.
Little did I dream that I was already doomed to drink to its dregs the
bitter cup of responsibility without authority. That story will come
soon enough; now I will ask the reader to accompany me in my work of
filling the shop with new tools.
My principal orders were sent to my old friends, Smith & Coventry,
in England. Among others I sent one for my double-drilling machine
with the drawings. I received a reply from them stating that they had
just furnished a similar machine to the firm of Hick, Hargreaves &
Company, the eminent engine-builders of Bolton, and that they thought
I would prefer their design for this machine, of which they sent a
blue print, to my own. I should think I did prefer it; it was simply
wonderful. It presented one feature of especial interest, which was
that the two drills were driven independently and when not employed
on connecting-rods could be applied to any other drilling work. So I
ordered that tool, and its work fully justified my expectations. I
ordered from them several planers, the largest one passing a body five
feet square. The planers they sent me had two novel features which
filled me with admiration. The tables were provided with broad, flat
shoes running on corresponding flat guides, the sideways wear being
taken up by an adjustable gib on one side. This construction enables
the bearing surfaces to be made one true plane from end to end, making
cross-wind impossible. The next feature by which these planers were
distinguished was the mode of lubricating these surfaces. Each guide
was provided in the middle of its length with an oil-well which was a
large square box, formed in the casting. In the middle of this box was
a small rod on which two levers were pivoted, the arms of which were
of equal length. At one end these arms carried a roller, and at the
other end a weight considerably heavier than the roller. The roller was
thus kept up against the under side of the shoe, while its lower side
ran in the oil; thus the lubrication was effected by the revolution of
this roller, which needed to be only one half the width of the face
lubricated; this was found to be the perfection of lubrication. The
tables were very stiff and were provided only with T slots from end to
end for holding the work.
I built a one-story addition to the erecting-floor, about 40×100 feet,
occupying a space which had before been used mostly as a stable. I
divided this into two bays by columns, and provided each bay with an
overhead traveler of about five tons capacity, worked by rope loops
hanging to the floor. These were also made for me by Smith & Coventry.
I ordered from Mr. Moore, of Philadelphia, one or two of the heavy
and powerful lathes built by him for turning chilled rolls. I also
ordered a six-foot square planer from the Hewes & Phillips Iron Works
in Newark, which they made expressly heavy, having become infected with
my ideas on that subject. From Pratt & Whitney I ordered one large
lathe and one or two small planers, and other tools from several other
American makers.
In one instance only I was disappointed; that was the case of a 12-foot
horizontal turning and boring machine. On examining the blue-prints
which were sent me at my request, I was struck with the lightness of
the table, and conditioned my order on this being made twice as heavy,
which was done. If I had made the same requirement for every other part
of the machine, I should have done a good thing for both the builders
and myself. The table ran on a circular track, which was superbly
designed. This track consisted of a circular trough perhaps 8 or 10
inches wide, and in the middle of it a bearing surface for the table,
raised perhaps half an inch above the bottom of the trough and half
an inch lower than its sides. This bearing surface was about 6 inches
wide and was intersected by diagonal grooves about a foot apart. Oil
could stand in this trough above the level of the bearing surfaces. I
made a little improvement on the method of supplying the oil. As sent,
a dose of oil was poured through a hole in the table, which was filled
with a screw plug when not required to be used. I screwed a plug into
that hole to stay, and drilled a hole in the bottom of the trough, in
which I screwed a ³⁄₈-inch pipe that I carried under the bottom of
the machine, and up behind one of the uprights to a higher level, and
in the end of this pipe I screwed a sight-feed oil-cup. I provided a
drain-pipe, which would maintain the oil in the trough at the desired
level, while it was fed to the trough continually, drop by drop, as
required. This table came with an imperfectly finished bearing surface.
I set several men at work to bed these surfaces properly, and did a
fine job of scraping on them. When it was finished, I pulled the table
around with one hand, it floating dry on the air caught between the two
surfaces. When we came to use the tool it chattered, and would do so
however light the cut we were taking; every part of it was too light
and vibrated, except the table. After all, it was the best tool of this
kind and size that I could have got in this country. If made of proper
strength I should have been able to use four cutting tools in the work,
each leaving a perfectly smooth surface; but that was a degree of
strength and usefulness that builders at that time had not dreamed of.
One of the first of our smaller engines, 10×20 inches, I built for
ourselves, setting it in a location convenient for transmitting power
to both the machine- and erecting-shops.
The job of taking the cross-wind out of the great planer interested
me perhaps more than anything else, on account of its difficulty. It
was a long time before I could decide how to go about it; besides the
cross-wind, the guides were not parallel; at one end the V’s on the
table bore on one side, and at the other end on the opposite side. I
finally made an apparatus consisting of two V’s about three feet long,
and connected by a cross-bar on which was set a spirit-level having
a ground bubble. Another similar level was set on top of one of the
V’s. With this apparatus, which was strong enough and was finished in
the most perfect manner, and a brass wire, I was able to determine
beforehand what was necessary to be done at every point in the guides.
To finish this job on the bed, and afterwards on the V’s under the
table, required fully three months’ work, including the time spent in
preparing the apparatus, a job I could not begin until I had our new
planers. When it was done I was able to make a perfect job of the great
engine beds already mentioned, and other work which was waiting for it.
Among the old tools was one large drilling-machine, the size of which
and the strength of its framing impressed me very favorably; but when
we came to use it we found it would not drill a round hole. This defect
could doubtless have been remedied by grinding the spindle, when we got
a tool in which to do it, and fitting new boxes. It was determined,
however, by Mr. Goodfellow and myself, that it would not be worth while
to bother with it, because it had been so badly designed that the two
traversing screws for the compound table, with which it was furnished,
were located centrally, and so crossed each other exactly under the
spindle. It was therefore impossible to use a boring-bar in this tool,
and its usefulness was ridiculously disproportioned to its size. The
contrast between it and the Smith & Coventry drill, which was set in
its place, was really wonderful. We had no trouble in disposing of
this and all other rejected tools to parties who were delighted to get
them cheap. It took us about six months to get rid of all the rubbish
and fill the works with the best tools then obtainable, though still
deficient in many respects, as, for instance, the great planer, which
had only one cutting tool on the cross-slide, whereas a planer of that
size should be provided with four cutting tools--two on the cross-slide
and one on each upright, and should be twice as heavy.
One of the first engines we sold was to D. M. Osborne & Co., the
celebrated makers of mowers and reapers in Auburn, for driving their
rolling mill. This was 18×30-inch engine, making 150 revolutions
per minute, and was the fifth engine I had furnished to different
industries in my native town.
Twenty-five years afterwards I saw this engine running. They had
increased its speed. By means of a large ball on projections of the
forked lever they were able to vary the speed from 200 revolutions to
250 revolutions per minute, according to the sizes they were rolling.
I observed that, as our facilities for doing work were increased, the
belief that I was unable to execute orders became general through
the country, and applications, at first numerous, dwindled to almost
nothing. United and well-directed action would soon have put a new face
on matters, but now I was to meet with obstacles that time could not
overcome.
Mr. Merrick was an amiable and high-toned gentleman, whose sole aim
was to do his duty; but he was exactly the wrong man for the place.
He was not an engineer or mechanic. In the firm of S. V. Merrick &
Sons he had been the office man. He was entirely a man of routine. He
seemed obtuse to a mechanical reason for doing or not doing anything.
Of course he knew nothing about my business. He was impressed with the
idea of the omnipotence of the president, which in his case was true,
as the directors would unanimously approve of whatever he might do. He
at once deprived me of the power of appointment and discharge in my own
department, arrogating all authority to himself. In addition he was
naturally a very reserved man, I may say secretive. He consulted me
about nothing. I never knew what he proposed to do or was doing until I
found out afterwards. He had grandly confessed his first two blunders,
but unfortunately he continued to make mistakes equally serious to the
end of the chapter.
About the first order we had was from a company formed for lighting
the streets in Philadelphia with arc lights, of which Thomas Dolan, a
prominent manufacturer in Philadelphia, was president. Our order was
for eight engines, 8×16 inches, to drive eight Brush dynamos each of
40-light power. The order was given to Mr. Merrick. I never saw Mr.
Dolan; his own mill was at the northern end of the city, and he met
Mr. Merrick by appointment at lunch in the business center, to which
conferences I was never invited. When the plant was in operation I
heard incidentally that they had a new engineer at the electric-light
works, and I thought I would go up and make his acquaintance. I went
the same evening. I was met at the door by a stranger who politely
showed me the plant. I did not introduce myself. He asked me if I were
interested in electric lighting. I told him I was not but might be. He
said it was his duty to warn me against the use of high-speed engines;
he should not have advised these, but found them already installed
when he took charge of the place, and he was doing the best he could
to make them answer for the present, but the works would be greatly
enlarged after a while, when these engines would be gotten rid of and
proper engines substituted in place of them. He called his assistant
to corroborate his statement of the difficulty they had in getting
along with them. I listened to these outrageous falsehoods and looked
around and saw the eight engines running smoothly and silently at 280
revolutions per minute, each engine exerting the power of four engines
of the same size, at the old maximum speed of 70 revolutions per
minute, and giving absolutely uniform motion without a fly-wheel, and
said nothing.
The next morning I made an early call on Mr. Dolan at his office. I
introduced myself to him, although I think he knew me by sight. I told
him the state of affairs I found at the electric-light station and
received from him in reply the following astounding statement. He said:
“Mr. Porter, when this company was formed I selected the Southwark
Foundry as our engineers. I had previously become acquainted with the
running of some of your engines and had come to the conclusion that
they were just what we needed; accordingly I ordered our first engines
from you. I assumed the engineering department of this enterprise to be
in your hands, and that you would be represented here by an engineer
selected by yourselves and devoted to your interest. Accordingly, when
your men had finished their job I applied to your president to send me
an engineer. He sent me a workman. That was not the kind of man I asked
him for; the engines were in charge of workmen already from your own
works. I wanted an educated man who could represent us in the courts
and before the city councils--in short, an engineering head for this
business, now in its infancy, but which was expected to grow to large
proportions. He ought to have known what I wanted, or if he did not he
should have asked me; his whole manner was entirely indifferent, he
seemed to take no interest in the enterprise.
“Seeing I could get no help from Mr. Merrick, I applied to
William Sellers for an engineer. He sent me a young man from his
drawing-office, and I soon found out he was not the man I wanted;
he knew nothing about a steam-engine--was merely a machine-tool
draftsman--so I found I must rely upon myself. The only man I could
think of was this man I have. He had done some good work for me two
or three years ago in repairing one of my engines, so I offered him
the position, which he accepted. I knew nothing of his engineering
preferences; he seems to be doing very well, and I am afraid he will
have to stay;” and stay he did.
The result was most remarkable. A demand for electric-lighting plants
was springing up in all parts of the country. This became widely
known as a pioneer plant, and was visited daily by parties who were
interested in such projects. These visitors were met at the door by
the engineer and his assistant and were warned, just as I was, to have
nothing to do with a high-speed engine. They were always business
men, quite ignorant of machinery, and with whom the testimony of two
practical men who had experience with the engines and were actuated in
their advice by a sense of duty was conclusive. The result was that we
never had a single application to supply engines for electric lighting.
Yes, we did have one application; a man came into the office when I
was there alone and gave me an order for his mill and apologized to me
for giving it. He said the place where he was obliged to locate his
lighting plant was so limited, he found he could not get in the engine
he wanted.
This result I felt especially exasperated at when a year afterwards the
secretary of the lighting company, who had his office at the station,
told me that he had done something of which he knew his directors would
not approve; he had sold every light they were able to furnish. He
had felt safe in doing this, because no one of the engines had failed
them for an instant. For his part he could not see what those men were
there for--they had absolutely nothing to do except to start and stop
the engines as required and attend to the oiling. Their principal
occupation seemed to be waiting on visitors.
This great disaster would have been avoided if Mr. Merrick had
conferred with me with respect to Mr. Dolan’s most important request.
We should have had a man there who would have told the truth about
the engines, and would have impressed every visitor with the enormous
advantage of the high-speed engine, not only for that service, but also
for every use to which steam power can be applied.
It will be observed that this disaster was widespread and continuous.
It not only caused a great immediate loss, but its ultimate injury was
beyond all computation. Its effect was that the Porter-Allen engine was
shut out of the boundless field of generating electricity for light
and power purposes, a field which was naturally its own.
The following story is too good to keep, although the incident had no
effect that I am aware of to accelerate my downward progress. While
in Newark I had built for Mr. Edison an engine for his experimental
plant at Menlo Park. The satisfaction this engine gave may be judged
by what follows: One day I had a call from Mr. Edison, accompanied by
Charles L. Clarke, his engineer. They had been walking very rapidly,
and Mr. Edison, who was rather stout, was quite out of breath. As soon
as they were seated, without waiting to recover his wind Mr. Edison
began, ejaculating each sentence while catching his breath: “Want a
thousand engines.” “Thousand engines.” “Want you to make the plans for
them.” “Have all the shops in New England working on the parts.” “Bring
them here to be assembled.” “Thousand engines.” In the conversation
that followed I gently let Mr. Edison down, not to the earth, but in
sight of it. The result was that two or three weeks afterwards I was
injudicious enough to accept from him an order for twenty-four engines,
luckily all of one size and type. This was to be a rush order, but it
called for new drawings and patterns, as he wanted a special proportion
of diameter and stroke, larger diameter and shorter stroke than those
in my table. Before the drawings and patterns were completed, Mr.
Edison, or the people associated with him, discovered that they had no
place to put more than six of these engines, so the order was reduced
to six. These were for a station which was being prepared on the west
side of Pearl Street, a few doors south of Fulton, New York City. Three
of these engines were finished first. After they had been running a
few days a defect of some kind, the nature of which I never knew, was
discovered, and Mr. Edison’s attention was called to it. He charged it
to the engine, and exclaimed impetuously, “Turn them out, turn them
out!” It was represented to him, however, that they could hardly do
this, as they were under contract for a considerable amount of light
and power, and the current was being furnished satisfactorily. “Well,”
said he, “we’ll have no more of them at any rate,” so the order for
the remaining three engines was countermanded, and three Armington &
Sims engines were ordered in place of them. When these were started
the same difficulty appeared with them also. A fresh investigation
disclosed the fact that the difficulty was entirely an electrical one,
and the engines had nothing to do with it. Mr. Clarke claimed that had
been his belief from the beginning. So the thousand engines dwindled to
three engines sold and three thrown back on our hands. The two triplets
ran together harmoniously until in the development of the electrical
business that station was abandoned.
Directly after we began to do work, Mr. E. D. Leavitt brought us the
business of the Calumet and Hecla mine. This was then the largest
copper mine in the country, owned by a Boston company of which Mr.
Agassiz, son of the great naturalist, was president. He brought it to
me personally on account of his admiration for the engine, and also
for the character of work which I had inaugurated. His first order was
for an engine of moderate size. While that was building he brought
us a small order for a repair job, amounting perhaps to a couple of
hundred dollars. That work was spoiled in the shop by some blunder and
had to be thrown away and made over again. By accident I saw the bill
for that job; a green boy brought it from the treasurer’s desk for Mr.
Merrick’s approval. We both happened to be out, and by mistake he laid
it on my side of the table. I came in first, picked it up and read it,
and saw that it was for the full amount of the material and work that
had been put on the job. It seemed to me quite double what it ought to
be. I laid it on Mr. Merrick’s side and, when he came in, told him how
I came to see it, and I thought it should not be sent, being so greatly
increased by our own fault. “Oh,” said he, “they are rich; they won’t
mind it.” I said: “That is not the question with me; I don’t think it
is just to charge our customers for our own blunders.” He smiled at
my innocence, saying: “If a machine-shop does not make its customers
pay for its blunders, it will soon find itself in the poorhouse.”
“Well,” said I, “I protest against this bill being sent.” However, it
was sent, and in the course of a few days a check came for the full
amount, and Mr. Merrick laughed at me. Weeks and months passed away and
we had heard no more from Mr. Leavitt, when I met him in New York at
a meeting of the council of the Society of Mechanical Engineers. When
the meeting was over he invited me to walk with him, and said to me: “I
suppose you have observed that I have not visited the Southwark Foundry
lately.” I told him I had observed it. He then said: “Do you remember
that bill?” I told him I did very well, and how vainly I had protested
against its being sent. He said: “When that bill was brought to me for
approval, I hesitated about putting my initials to it until I had shown
it to Mr. Agassiz. I told him what the job was and the bill was quite
twice as large as I had expected. He replied, ‘Pay it, but don’t go to
them any more,’ and I have taken our work to the Dickson Manufacturing
Company at Scranton.” I realized that I had lost the most influential
engineering friend I had since the death of Mr. Holley. I heard some
years after, and believe it, though I do not vouch for its correctness,
that the work sent to the Dickson Manufacturing Company through Mr.
Leavitt had in one year exceeded one hundred thousand dollars.
[Illustration: E. D. LEAVITT]
Some time previous to these events, Mr. Merrick had done a very
high-handed thing. Assuming supreme power as president of the company,
he had invaded my department, and, without a word to me, had appointed
over Mr. Goodfellow a superintendent to suit himself, reducing Mr.
Goodfellow to be general foreman of the machine-shop, to take his
orders from the new superintendent and not from me, whereupon Mr.
Goodfellow resigned, and accepted a position as master mechanic in
the Pennsylvania Steel Works, and by his advice the engine ordered by
them from me was taken from the Southwark Foundry in its incomplete
condition and finished by themselves under Mr. Goodfellow’s direction.
Mr. Merrick then filled Mr. Goodfellow’s place with another friend of
his own as general foreman, a man who would have been as valuable as
a stick of wood but for his incessant blunders. I was fully alive to
the arbitrary nature of this usurpation, but was entirely helpless,
knowing perfectly well that the directors would sustain the president
in whatever he did.
With the coming of the new superintendent, the fatal change took
place. He came, first of all, full of the superiority of Philadelphia
mechanics, and, second, feeling that in the nature of things I must
be entirely ignorant of anything mechanical. I was nothing but a New
York lawyer; never did a day’s work in a shop in my life; had gone into
a business I was not educated to and knew nothing about. My presuming
to give orders to mechanics, and Philadelphia mechanics too, filled
him with indignation. He would not take an order from me--perish the
thought--and as for my drawings, he would depart from them as much as
he liked.
All this appeared by degrees. I observed on the floor several cylinders
fitted up, in which the followers for the piston-rod stuffing-boxes
were made sliding fits on the rods. I asked him why he had made them in
this way when they were drawn and figured to be bored ¹⁄₃₂ inch larger
than the rod. He replied, “Because this is the way they ought to be.”
I told him every one of them would be fired before the engine had run
an hour; that I wanted him to bore those followers to the drawings,
as well as the cylinder heads back of the stuffing-boxes. “It shall
be done, sir,” said he. On examining them after this had been done, I
found he had turned as much off from the outside of the followers as he
had bored out of the hole. I asked him why he had done that. He said he
supposed if I wanted the inside to be loose, I wanted the outside to
be loose too. I told him I did not. He asked me why. I told him he was
not there to argue with me; I wanted him to throw those followers away
and make new ones precisely to the drawings, and I saw to it myself
that it was done. I went to Mr. Merrick about this matter, and can
the reader imagine what his reply was? “My advice to you, Mr. Porter,
is to leave all such matters to the superintendent.” Think of it; an
amateur president assuming the direction of my business, and giving
such advice to me, who never had left the least thing to anybody, and
without considering the fact that the action of his superintendent
would be ruinous, except for my interference. I realized that I was
absolutely alone, but I felt very much like fighting the whole world.
The above incident is a fair sample of my constant experience. I was on
the watch all the time. Many times I required the work to be done over
when the superintendent departed from my drawings, and in doing it over
he generally contrived to ruin the job, and would say, “Just according
to your orders, sir.” I was reminded of a story told of Dr. Beman, a
minister of Troy, N. Y., whose wife was peculiar, to say the least.
On a certain occasion the presbytery met in Troy, and one evening he
invited its members to his house, and told his wife to provide just a
light supper. When they were ushered into the supper-room there was
nothing on the table but lighted candles. “A light supper,” said she,
“just as you ordered, sir.”
[Illustration: SAMUEL T. WELLMAN]
I proposed to appoint an inspector to represent me. The general foreman
said if an inspector were appointed he should resign, and Mr. Merrick
forbade it. Was ever a man in so helpless and ridiculous a position?

The second of the large engines which I finished was for the Otis Steel
Works. I went to Cleveland myself to start the engine and found that
Mr. Wellman, the general manager, had it running already. Mr. Otis, the
president, was very much pleased with it, and well he might be. This
was the first mill to roll plates from the ingot to the finish without
reheating. These were the kind of diagrams it made. It will be observed
that these were taken at different times and under different pressures.
Unfortunately the right hand one is the only diagram I have from the
crank end of the cylinder. In rolling these heavy plates the changes
were made instantaneously from full load to nothing and from nothing to
full load. The engine made 93 revolutions per minute, and it will be
seen that the changes were made by the governor in a third of a second
or less, the speed not varying sensibly. Mr. Otis said to me: “Oh, Mr.
Porter, what shall I do with you? You cannot imagine the loss I have
suffered from your delay in furnishing this engine.” I said: “Mr. Otis,
you know the terrible time I have had, and that I have done the very
best I could.” “Yes,” he said, “I know all about it.” He had, in fact,
been to Philadelphia and seen for himself. He added: “You make a small
engine suitable for electric lights; what is the price of an engine
maintaining twenty-five arc lights?” I told him $1050. “Well,” said
he, “you strike off the odd fifty and let me have one for a thousand
dollars, and we will call it square,” so I had some sunshine on my way.
I present a portrait of this just man. The engine is now running as
good as new after twenty-five years, and the company five or six years
afterwards put in another 48×66-inch to drive a still larger train.
I had a funny experience at the Cambria Works which has always
seemed to me to have been prophetic. In August, 1881, the Society of
Mechanical Engineers held a meeting in Altoona, and the Pennsylvania
Railroad Company gave us an excursion to Johnstown to visit the works
of the Cambria Company. The anticipations of the members were expressed
by Jackson Bailey, then the editor of the _American Machinist_. As
I was going through a car in which he was seated he called out to
me, “This is your day, Porter.” The party was taken in charge by
Mr. Morrell, the general manager. Our route took us first to their
new blast-furnaces, where considerable time was spent in examining
their new and interesting features. Next we came to my second engine,
started some two months before. The engine was just being slowed down;
we were told there were not yet furnaces enough to keep the train
running continuously, so they were shut down from half an hour to an
hour between heats, and a heat had just been run off. We went next to
see my rail-mill engine, which had raised the output of that mill 150
per cent. That too had been shut down. They had just broken a roll, a
most rare accident and one which I had never before seen or heard of
there. “Well, gentlemen,” said I, “at any rate I can show you my engine
driving a cold saw.” Arrived at the spot, we found that all still, and
were told that sawing cold rails was not a continuous operation, we had
hit upon the noon hour, and the men had gone to their dinner. That was
the end of the show, as far as I was concerned. The Gautier Works were
a mile away and were not included in our visit, so we were entertained
with the great blooming-mill in operation and the casting of the
enormous ingots for it, and after the customary luncheon and speeches
we returned to Altoona.
[Illustration: CHARLES A. OTIS]
One day the superintendent came into the office and told me he had
tried my machine for facing nuts and it would not work. I felt
disappointed, because I had confidence in it. I went out to see what
the matter was, and at a glance I saw that it had been ingeniously
arranged not to work. The feed had been made rapid and the cutting
motion very slow, so that the tools could not take their cuts and the
slow-moving belt ran off the pulleys. I did not reduce the feed-motion,
but increased the speed of the cutters and the belt some eight or
ten-fold, when the trouble vanished. I never knew anything to work
better than that tool did.
[Illustration: Porter-Allen Engine 40″×48″ #207
Dash pot for Governor.]
The burning anxiety of the superintendent was to show up my ignorance.
A first-rate chance to do so soon seemed to present itself. The
counterpoise of the governor of the Otis engine dropped instantly to
its seat when a plate struck the rolls and as instantly rose to the top
of its range of action when it left them. This made a noisy blow which
was disagreeable and might in time cause an accident. Mr. Wellman sent
me a sketch of a device he had thought of for arresting this motion by
air-cushions. I told the superintendent to have that apparatus made
and make the air-cushions four inches in diameter. He said four inches
diameter would not answer; they must be eight inches. “No,” said I,
“four inches diameter is ample; make them four inches.” A few days
after he called me into the shop to try my four-inch air-cushions. I
found the apparatus secured in a vise in a vertical position. I took
hold of the lever and lifted the piston; it met with no resistance
until it struck sharply against the end of the chamber. For a moment
I was stunned by the man’s audacity, and threw the piston up and down
again to make sure it was not a dream. I then turned my back on the
superintendent and called to a boy to find Mr. Fulmer, the foreman
of the second floor, and tell him I wanted him here. In a moment he
appeared, and I said to him: “Mr. Fulmer, I want you to make a new
piston for this apparatus and make it a proper fit; you understand.”
Mr. Fulmer bowed assent. I added: “There will be time to-day to get it
into the sand, and it can be finished early to-morrow. When it is ready
for my inspection come yourself to the office and let me know.” About
the middle of the next forenoon Mr. Fulmer called for me. I went in
and found the piston arrested at each end of its motion by a perfect
air-cushion. “All right,” said I, “see that it is shipped to-day.”
Mr. Fulmer was an excellent mechanic and a man of good general
intelligence; he would have made the piston a proper fit in the first
place if he had not been expressly ordered to make it loose and
useless. The superintendent, on his persistent assumption that I was
a fool, had actually expected me to say when I tried the apparatus:
“Oh, I see, four inches diameter will not do. You will have to make it
eight.”
Some time in 1881 or 1882 I had a queer experience with an engine for
the New York Post Office. It was to take the place of an engine then
running. The engineer of the Post Office informed me that this engine
had a cylinder twelve inches in diameter. I told him it looked to me
from the external dimensions that the diameter must be fourteen inches
and asked him to take off the back head and measure it for me. He wrote
me a few days after that he found that he could not get the back head
off, but I might rely upon it being twelve inches. So I did rely upon
it being fourteen inches, furnished an engine accordingly, and found it
to be the size needed.
[Illustration: DANIEL J. MORRELL]
Some time after the engine was started I received a line from the
Postmaster saying they were much disappointed in it. They expected a
gain in economy, but they were burning more coal than before, also that
the engine pounded badly. I went to New York to see what the matter
was. The engine seemed to be working all right except for the knock, so
I made my way down to the sub-cellar. There was nothing there but the
boilers and the engineer’s desk. On the cellar stairs, after I had shut
the door behind me, I heard a loud sound of escaping steam. The boilers
were under the middle of the building; a four-inch steam-pipe ran from
them a distance of about eighty feet, suspended from the ceiling, to a
point under the engine, then turned up through the floor to the under
side of the steam-chest. The exhaust pipe, of the same size, came
from the engine through the floor and was carried parallel with the
steam-pipe to the middle of the building and upward through the roof.
The two pipes were about eighteen inches apart, and in the vertical
portions under the ceiling they had been connected by a half-inch pipe
having a globe valve in the middle of its length. The valve-stem was
downward and the valve set wide open. The noise I heard was caused by
the steam rushing through this pipe. I computed that about as much
steam was being thus blown away as was used by the engine. My first
impulse was to call upon the Postmaster and tell him what I had found,
but I decided not to bother him. I could not reach the valve to close
it, but discovered a box used for a step to an opening in the wall, so
I brought that out and standing upon it was able to close the valve;
then the noise ceased and I put the box back.
There was no one in the cellar but a boy firing the boilers. I asked
him if he knew who put that pipe there. He knew nothing about it, but
supposed our men put it there when they set up the engine. I hunted
up the engineer and asked him the same question, and got the same
answer. I went to the people who did the engineering work for the Post
Office and who had put in the pipes; they knew nothing about it. I
could find out nothing, but had to content myself with telling the
engineer that I had closed the valve and relied upon him to keep it
closed. I asked him what he thought caused the thump in the engine;
he said he had not the slightest idea, but he would try to cure it.
I contented myself with writing to the Postmaster that I had removed
the cause of the waste of steam and hoped he would now find the engine
satisfactory. Soon after Mr. Merrick was in New York for two or three
days. When he came home he said: “I have cured the thump in that Post
Office engine.” “How did you do it?” I asked. He replied: “I gave the
engineer a twenty-dollar gold piece, and when I went to see it the next
morning the thump was gone.” I should add that when the old engine was
taken down I had the back cylinder head removed, which was done without
difficulty, and found the diameter fourteen inches. “For ways that
are dark and tricks that are vain” this engineer was “peculiar” in my
experience.
I had brought with me from Newark an order from the Willimantic Linen
Company, who were manufacturers of cotton thread, for two engines
for quite an interesting application. They were building a new mill
entirely unique in its design, which has never been repeated, being an
ignorant freak. It was a one-story mill 800 feet long and 250 or 300
feet wide, intended to contain five lines of shafting. Each line was
independent and drove the machinery for all the successive operations
from opening the cotton bales to packing the spools of thread. These
lines of shafting 800 feet long were to be in the basement and to drive
these machines by belts through the floor, the engine to be in the
middle of each line. For this purpose I supplied a pair of condensing
engines, 11 inches diameter of cylinder and 16 inches stroke, making
350 revolutions per minute, with their cranks set at right angles
with each other in the line of shafting. These required no fly-wheel
and would start from any position. I had a great deal of trouble with
this order on account of the delay in its execution, so much so that
before the first engine was finished the order for the second one was
countermanded, and this order was placed with the Hartford Engineering
Company, a new concern which was foolish enough to undertake the same
speed. However, after my first engine was started they found themselves
face to face with an impossibility and had to throw up their contract,
whereupon the president of the company became very civil and asked me
to be kind enough to make the second engine for them, which I was quite
happy to do, as I had on hand the peculiar bed for these engines, which
I did not break up after the order was countermanded, but had it set up
against the wall of the shop in readiness for what might happen. These
two engines were both in successful operation when my own operations
ceased; the remaining three engines were to be added as their business
required.
The engineer of that company was an original investigator. He had a
battery of return-tubular boilers, each one crammed full of tubes
according to the usual methods of boiler-makers. He provided himself
with pieces of lath one inch wide, one eighth of an inch thick, and
four inches long, and laid one in the front end of each tube in one
of his boilers and left them there for twenty-four hours. He had made
a diagram of his boiler on which he numbered every tube and put a
corresponding number on every piece of lath. In taking them out they
presented an astonishing revelation, which he showed me. Some of the
pieces were burned almost to a coal and some were scarcely discolored,
while the great body of them presented various effects of heat between
these extremes. These showed distinctly the enormous differences in
the temperature of the gases passing through the different tubes, and
that fully one half of the tubes did little or no work in evaporating
the water. They taught a lesson which boiler-makers, who count every
additional tube they can get into a boiler as so much added heating
surface and rate their boilers accordingly, have no anxiety to learn,
but which I afterwards turned to good account, as will be seen.
About the last and the most interesting engine that I built
while in Philadelphia was one for the firm of Cheney Brothers,
silk-manufacturers, of South Manchester, Conn. This was a
cross-compound, the first and the last compound engine that I ever
built, and it is the only engine in this country to which I applied
my condenser. The cylinders were 12 and 21 inches in diameter, the
stroke 24 inches, and the shaft made 180 revolutions per minute. The
condenser presented a new design in one respect; the air-pump was
double-acting and made only 45 double strokes per minute, being driven
by a belt from the engine shaft and the motion reduced by gears 1 to
4. This engine ran perfectly from the start, and I looked forward with
confidence to a demand for many more of the same type. The diagrams
made by it are here reproduced.
[Illustration:

I have a pleasant memory connected with this engine. The silk-mill is
located in a very large park, scattered about which are the residences
of different members of the family. About twelve years after the
engine was built, in company with my wife, I was visiting relatives in
Hartford, from which South Manchester is about twelve miles distant.
One day we were driven over there with our friends to make a social
call. On our arrival I left the party to make a visit to my old engine.
The mill seemed to have been changed very much, and I lost my way.
Finally I recognized, as I thought, the old engine-room and went in.
My engine was not there, but in its place stood another engine, a pair
of tandem compounds of much larger dimensions. These had evidently
just been erected, as they stood idle. “Oh, dear,” said I to myself,
“my engines have been superseded for some reason or other.” While I was
indulging in that reflection the engineer came in. I introduced myself
and said to him: “I see that my old engines have been supplanted.” “Oh,
no,” said he, “your engines are all right; they are running just where
they always have been. They have built a new mill twice as large as the
old one, and your engines have been giving such satisfaction they have
ordered another pair of compounds from the Southwark Foundry, and these
are the engines; they have not been started yet, as the mill is not
ready for them and won’t be for a month.”
He directed me to the old engine-room, where I found my engines gliding
away as though they had been erected yesterday. At that time I regarded
these engines as only a stepping-stone to far higher things. I was
engaged on a plan for a great development of the high speed system,
but which has not materialized. I still consider it as on the whole
superior to the turbine, a superiority, however, which may never be
established.
In the spring of 1881, in our anxiety to revive the manufacture of the
engine, we were foolish enough to send one to the Atlanta exhibition.
We eagerly believed the promises of the agent that we should find all
the machinery that we wanted to drive, and sent an engine finished with
great care, and a skillful man to erect and run it. We also printed the
heading of a lot of diagrams, to be given to visitors. The facts were
found to be that we had nothing to drive but an idle line of shafting
and one Clark’s spool-winder, while the exhaust main was so small and
choked with the exhausts from other engines that we had a back pressure
of ten pounds above the atmosphere; so we could take no diagrams; and
the fact that we did not take any was used as a conclusive argument
against high-speed engines; so the exhibition did us harm instead of
good.
I pass over other distressing experiences at the works, and come at
once to the final catastrophy in the late fall of 1882.
Another exhibition opened in the fall of 1882, for which I made great
preparations, and from which I anticipated important results. This
was the exhibition of the New England Manufacturers’ and Mechanics’
Institute, held in Boston. I obtained an important allotment of space
with plenty of machinery to drive, and, besides a fine engine, sent
a large exhibit of our finished work, in the parts of several sizes
of engines, expecting to attract the attention of all New England
manufacturers. I prepared for a regular campaign. I rented an office
and engaged a young man to represent us in Boston as our agent, and
another, Mr. Edwin F. Williams, to travel and solicit orders and
take the charge of erecting engines. Our engine arrived without a
piston. Mr. Merrick had thought he had found a defect in the piston,
and ordered another one to be made. When we came to put the engine
together in the exhibition, this piston would not enter the cylinder.
On examination it was found to have been turned conical, the bases
of the two cones meeting in the middle, so the middle was one eighth
of an inch larger in diameter than the faces. We had to get a coarse
file and file down the middle of the piston all around until it would
enter the cylinder. Then I had a great disappointment--the greatest I
ever experienced--the engine thumped badly on both centers. The only
way in which we could stop the thumping was by shutting off the steam
until the initial pressure was brought down to the height reached by
the compression of the exhaust. In this plight we had to run through
the exhibition. We could not take a diagram and had to watch the engine
constantly, for whenever the pressure rose ever so little too high in
the cylinder it would begin to thump. I attributed this to the shocking
condition of the surface of the piston. I could not comprehend how this
should cause the thump, but it must be that, for I could conceive of
nothing else that could produce it. This thump made my exhibition a
total failure, and necessitated the abandonment of all my plans.
At the close of the exhibition I went home utterly discouraged. When I
went into the shop the first person I met was the foreman of the lower
floor, where the engine had been built. I told him of the plight in
which I found myself placed and to which I attributed my failure. The
fellow gave me the lie direct, saying with a conceited smirk: “It is
impossible, Mr. Porter, that any such work as you have described can
have gone out of this establishment.” I turned on my heel and left him,
and in less than half a minute I saw at a distance of fifty feet a
22-inch piston being finished for an engine we were building for the
Tremont and Suffolk Mill. The workman had finished turning the piston
and was then cutting the grooves for the rings. The reflection from
the surface showed me the same two cones meeting in the middle. I went
up to the lathe, the back side of which was toward me, and told the
workman to stop his lathe and bring me a straight-edge. This rocked on
the edge in the middle of the piston, opening nearly one eighth of an
inch on each face alternately. I sent a boy to find the foreman and
asked him what he thought of that and left him. I had influence enough
to have both the foreman and the workman discharged that night. Think
of it; superintendent, general foreman, the foreman of the floor, and
workman, altogether, never saw what I detected at a glance from the
opposite side of the shop.
I want to stop here to express my disgust with the American system of
making the tailstock of a lathe adjustable, which enables either an
ignorant, careless or malicious workman to ruin his work after this
fashion. To their credit, English tools have no such feature.
The very next day we received a call from Mr. Bishop, the engineer of
the works of Russell & Irwin at New Britain, Conn., to tell us that
their engine just put in by us had a very bad thump which he was afraid
could not be cured as it was evidently caused by the piston projecting
over the admission ports when at the end of its stroke. “Impossible,”
I exclaimed; “I never made such an engine in my life.” I should here
state that in experimenting with the first little engine that I made
before I went to England, I at first made the piston project over the
port one quarter of an inch, and the engine thumped. I satisfied myself
that this was caused by the impact of the entering steam against the
projecting surface of the piston, driving it against the opposite side
of the cylinder; this was aggravated in high-speed engines. In this
case the engine made 160 revolutions per minute and the steam was
admitted through four simultaneous openings, so it entered the cylinder
with great velocity. I turned a quarter of an inch off from each face
of the piston, and the thump disappeared. I then made it a law from
which I never varied, that the piston should come to the admission
port and not project over it at all, and this feature was shown in
every drawing.
Mr. Bishop replied to me: “It does project, Mr. Porter; it projects
seven eighths of an inch over the port at each end of its stroke, for
I have measured it.” I rushed up to the drawing-office and called for
the horizontal sectional drawing of that cylinder, and there I saw the
piston not only drawn, but figured--projecting seven eighths of an inch
over the port. I felt as though I were sinking through the floor. That
was what had ruined my Boston exhibition and sent me home disgraced and
broken-hearted and the badly fitting piston, shameful as that was, had
nothing to do with it. The first question that occurred to me was: “How
came this drawing to exist and I to know nothing about it?” The answer
to this question was simple.
When the first pair of Willimantic engines was started I was
disappointed in their economy, and made up my mind that the excessive
waste room was accountable for it. The proportion of cross-section
area to the stroke being fifty per cent. greater than in my table of
sizes increased in the same degree the proportion of waste room to the
piston displacement. I felt that there was need here for improvement.
By far the greatest amount of waste room was in the exhaust ports. I
accepted a modification of the exhaust valves by which this item of the
waste room was reduced fully one half and made a new pair of cylinders
for this engine. The improvement in the economy was so marked that I
determined to change the exhaust valves of all the engines. Only the
exhaust valves and ports needed to be changed. These were drawn anew in
pencil and carefully studied and approved of by me. It was necessary
that the entire combined cylinder drawing should be retraced, but this,
except only the exhaust ports and valves, was to be copied over the
existing tracings. This did not require my attention, and I gave no
thought to it. Here was the superintendent’s opportunity. In copying
these tracings he had only to move the straight line representing
each face of the piston on the longitudinal section of the cylinder
seven eighths of an inch, thus adding this amount to the piston at
each end, and shorten the cylinder heads to correspond, and the job
was done; and there did not exist among the large number of persons in
the drawing-office and shop who must have been aware of this change,
loyalty enough to let me know anything about it.
We had also recently finished two engines for the Cocheco Mill at
Dover, N. H., and about this time we received a letter from the
superintendent of that mill expressing his admiration of the engines in
every other respect, but complaining of a bad thump in the cylinders.
He said he would be glad to invite the superintendents of other mills
to see them, but he could not show the engines to anybody until that
thump was cured.
I went directly to the president and demanded authority to change the
pistons and heads of these engines. To my astonishment he refused
point-blank, saying he had spent money enough on these alterations, and
he would not spend another cent. I replied to him that there was one
other alternative and that was to abandon the business, to which he
made no reply. But why did I need to go to the president; why not make
these changes myself? The answer to this question is very humiliating
to me. An account had been made up of the cost of the alterations here
described and presented to the board of directors, showing this to
amount to $20,000. I was aghast at this statement; I had never seen
a figure pertaining to the business, except the single bill already
mentioned. I told the directors that any good pattern-maker would have
taken the contract to alter those exhaust valves and ports on our
twenty sizes of cylinders for an average price of fifty dollars each,
and made a profit of fifty per cent. in doing it. The cost of the new
drawings and the price of cylinders for the Willimantic engine could
not more than double this sum, and by some hocus-pocus this $2000
had been changed to $20,000; probably by transfer from other losing
accounts. The president replied that was the cost of the alterations
as it appeared on the books, and the directors, without making any
investigation, adopted a resolution that no further alterations should
be made unless expressly ordered by the president.
I did not believe that in making this addition to the length of the
piston the superintendent had any intention to wreck the business. He
could have had no idea of its fatal nature; his only thought was to
make a considerable further reduction of waste room and gratify his
itching to change my drawings. But of course doing this without my
knowledge was criminal, and should have caused his instant discharge;
but his whole conduct from the beginning had been the same and the
president had sustained him. I had no opportunity to pursue this matter
further.
On receiving the president’s refusal I determined to appeal to the
directors, but first I thought I would lay the matter before Mr. Henry
Lewis, whom I regarded as the most open-minded of all. What was my
amazement when, after listening to my statement, he replied: “We shall
sustain the president, Mr. Porter.” Then I knew the end had come. It
was idle for me to butt against the Philadelphia phalanx. A day or two
after a committee of the directors headed by Mr. Shortridge, called at
the office and asked to see our order book. This showed that in more
than a month preceding we had not received a single order. On this
state of affairs it was evident to the directors that a change must be
made in the management. I had long realized that the great gulf that
I had dug between the stockholders and myself, as already described,
had never been filled. Neither the directors as a body, except on the
single occasion already mentioned, nor any director individually, had
ever conferred with me on any subject whatever. They knew nothing,
except what they might have learned from the president; he had no
mechanical knowledge or ability to form a mechanical judgment,
and the superintendent influenced him in a degree which to me was
unaccountable. His want of comprehension of the business was shown in
his answer to the life-or-death question which I had presented to him.
The next day I received a communication from the directors requesting
me to send in my resignation, which I promptly did. Mr. Merrick was
also requested to resign. This was evidently a put up job, to let
me down easy. Mr. Merrick had for some time expressed a wish to be
relieved from his position which he found very uncomfortable.
The directors elected as president one of their own number, who had
nothing else to do, to sit in the president’s chair and draw his
salary, and committed the practical management of the business to an
oily-tongued man who had never seen a high-speed engine, and whose
qualifications for the position were that he was a friend of one of the
directors and was a Philadelphian, and who I learned received a large
bonus for leaving his own business and accepting the position vacated
by me.
