VOL. XVII., No. 26....[NEW SERIES.]...._Twenty-first Year_.

NEW YORK, SATURDAY, DECEMBER 28, 1867.

* * * * *

THE LAST NUMBER OF VOLUME XVII.

We give in this number a full index of the volume of which this is

the last issue. No doubt this will be more satisfactory to our

readers--those at least who preserve their numbers for binding, and

probably most do--than publishing the index in a separate sheet. The

list of claims in this number will be found to be unusually full, a

gratifying evidence that dullness of business does not cripple the

resources nor abate the industry of our inventors. With a parting word

of good will to our present subscribers and a welcome to those who begin

with our new volume, we wish for all a HAPPY NEW YEAR.

* * * * *

COMMENCEMENT OF A NEW VOLUME.

With the next number the SCIENTIFIC AMERICAN enters upon its

twenty-third year. Probably no publication extent will furnish a more

complete and exhaustive exhibit of the progress of science and the arts

in this country for the past twenty-two years than a complete file of

the SCIENTIFIC AMERICAN. It is a curious and interesting pastime to

compare the condition of the mechanic arts as presented in some of our

first volumes with that shown in our more recent ones. During all this

time, nearly a quarter of a century, our journal has endeavored to

represent the actual condition of our scientific and mechanical progress

and to record the discoveries and improvements in these departments

wherever made. The result is a compendium of valuable information

unattainable through any other means.

But the SCIENTIFIC AMERICAN has aimed not only to gratify a laudable

curiosity by collecting and presenting such information, but to give

practical knowledge which could be applied to valuable uses.

We labor for the producers--the mechanics, farmers, laborers--those who

build up a country and make the wilderness to blossom like the rose. We

believe that the workers are the power, especially in this country; and

while we do not wish to detract from the value of the products of merely

intellectual speculators, we still think that the world needs specially

the laborer. We use the term "laborer" in this connection in its widest

sense, comprehending he who uses brain as well as he who employs muscle;

scientific investigation and discovery should be followed by and united

to practical application.

The improvement exhibited in our past volumes will be no less noticeable

hereafter. Keeping pace with the "march of mind" we shall endeavor

always to lead rather than to follow. The different departments of our

paper are managed by those who are practically acquainted with the

subjects they profess to elucidate. "To err is human," but we shall

spare no pains nor expense to make the SCIENTIFIC AMERICAN as reliable

in its statements as it is interesting in the variety and matter of its

subjects. There are none of our people, from the student or professional

man to the day laborer, but will find something in every number, of

present or future value to him in his business.

A CHANGE AT THE PATENT OFFICE.

T.C. Theaker has resigned as Commissioner of Patents. A number of

gentlemen are mentioned as candidates for the succession, prominent

among whom are B. T. James and Charles Mason. Mr. James has acted in the

capacity of primary Examiner in the Engineering Class for a number of

years, and has filled his position acceptably. Judge Mason held the

Commissionership from 1853 to 1857, and his whole administration was

marked with reform and ability. Judge Mason was educated at West Point,

and he is a man of sterling integrity, a sound jurist, experienced in

patent law, and a splendid executive officer. One thing may be relied

upon, if Judge Mason should receive and accept the appointment of

Commissioner, inventors will not have to complain long of delay in the

examination of their cases The Judge is as industrious by nature as he

is stern and systematic by education and he will have no drones about

him. The work of the office under his administration would be brought up

and kept up.

A good day for inventors and all persons having business with the Patent

Office will dawn when Judge Mason takes the Commissioner's chair again,

and we hope the proper influences may be brought to bear to secure his

acceptance.

OBITUARY.

Ebenezer Winship, died at his home in this city Dec. 6, 1867, at the age

of 67. A long and eminently useful although unobtrusive life entitles

his memory to respect. He commenced his career as a mechanic in

the steam engine establishment of James P. Allaire, soon after the

application of steam for the propulsion of boats and long before its

application to ships for the purposes of commerce or war. For fifty-two

years, with the exception of one or two brief intervals, he was

connected with the Allaire works in this city, and for more than forty

years he was the master mechanic and general superintendent of the

works. Probably no man now living has had a more intimate connection

with the construction of the marine steam engine in all its remarkable

changes and improvements, or been so long employed at one engine

establishment.

James P. Allaire, the founder of the Allaire Works, died May 20,1858, at

the age of 73. He was an intimate acquaintance of Fulton and from the

engine of Fulton's first boat, the _Clermont_, took drawings which he

used in the construction of his first marine engines. He built the

engines for the _Chancellor Livingston_ which ran between New York and

Albany. He built also the first marine engines ever constructed in this

country, which were put into the steamship _Savannah_, the first steamer

that crossed the Atlantic, and also those for the _Pacific_ and

_Baltic_ of the Collins line, which ships surpassed in speed any before

constructed.

Under such tutelage and with such advantages Mr. Winship rose

successively through the grades of apprentice, journeyman, boss,

and foreman, to the position of master mechanic and superintendent.

Connected intimately with the progress of marine engineering for over

half a century, he was the teacher of a large number of our engineers

who now reflect credit upon their instructor. Mr. Winship's professional

skill was unsurpassed; his ability in directing and managing others and

thorough acquaintance with the minutest details made him invaluable in

the position he so long honorably filled. His personal characteristics

were faithfulness, industry, earnestness, kindness of heart, and

unvarying punctuality and promptness. As master mechanic it was his

invariable rule to be at the works an hour before the time for beginning

labor to lay out the work for the hands, getting his breakfast in winter

by gas light and returning from dinner in time to see the condition

of the work before the men arrived. In short, he made his employers'

business his own and neglected nothing which might contribute to their

success. He was a connecting link between the present generation of

mechanics and that which saw the beginnings of that great power, steam,

which has revolutionized the world. His funeral on the 8th of December

was attended by all the employés of the Allaire Works, by many from

other mechanical establishments, and a large number of citizens.

How to Make Intelligent Workmen--Go and Do Likewise.

Mr. H. O. Osborn, of Castleton, Vt., in a letter covering an order for a

club of subscribers, says:--"It may not be uninteresting to you to learn

that the last six names are those of young men in my employ. I have

myself been your subscriber for the past four years, and knowing as

I did the value of your paper, I felt it a duty I owed to my men to

recommend the paper to their notice, and the result is as above. I am

proud to think that I have so many in my mill who can appreciate its

worth. I hope at no remote date to send you another list of names from

among my own men, and I am certain that if every manufacturer would

consult his own best interest he would do all he could to place your

paper in the hands of his workmen, for I feel it to be a valuable

acquisition to all in any way connected with machines."

We believe that employers who wish to improve the condition of their

employés can render them no better service than to make each of them a

Christmas present of a year's subscription to this paper. Send in the

names early, so that we may know how large an edition to print to

supply the demand. We close this Volume with over 30,000--nearly

35,000--subscribers, and we wish to commence the new with at least

50,000. Send in your names.

The Iron-Clads at Sea.

In his last annual report to Congress, the Secretary of the Navy thus

refers to the cruise of the _Miantonomah_ to Europe and her return and

of the _Monadnock_ to San Francisco, voyages the most remarkable ever

undertaken by turreted iron-clad vessels. These vessels encountered

every variety of weather, and under all circumstances proved themselves

to be staunch, reliable sea-going ships. The monitor type of vessel

has been constructed primarily for harbor defence, and it was not

contemplated that they would do more than move from port to port on our

own coast. These voyages demonstrate their ability to go to any part of

the world, and it is believed by experienced naval officers that with

slight modifications above the water line, in no way interfering with

their efficiency in action, they will safely make the longest and most

difficult voyages without convoy.

Steam, turreted iron-clads and fifteen-inch guns have revolutionized

naval warfare, and foreign governments, becoming sensible of this great

change, are slowly but surely coming to the conclusion that turreted

vessels and heavy ordnance are essential parts of an efficient fighting

navy.

THE SCIENTIFIC AMERICAN AS A MEDIUM OF BUSINESS.

We seldom publish the favorable opinions expressed by our correspondents

when in their letters they allude to this journal. If we chose we could

fill columns with notices similar to those which follow.

R. S. Miller of Logansport, Ind., under date of Dec. 2d, says:--

I have a club of 10 or 12 engaged, and will send names and money about

the 20th inst. I have been reading the SCIENTIFIC AMERICAN for several

years and frequently I find items in it of more value than the year's

subscription. In No. 9, present volume, you illustrated a plan for

setting steam boilers. I was much pleased with it and showed it to a

friend of mine who was about re-setting a 60-horse power boiler in his

machine shop. He adopted the plan. Four week's use of the improved

furnace proves all you claimed for it. My friend will be one of your new

subscribers. I shall, in a few days, re-set my 15-horse power boiler

according to the plan. Every live mechanic should take your valuable

journal.

The Lamb Knitting Machine Manufacturing Co, Chicopee Falls, Mass.,

say:--

In payment of your bill please find inclosed draft, etc. Please insert

our advertisement every other week hereafter. We are compelled to this

being overrun with orders. Unless they hold up we shall be obliged to

withdraw it entirely. So much for the advantages of your medium for

advertising.

C.W. Le Count, Manufacturer of lathe dogs and steam engine governors,

South Norwalk, Conn., writes concerning his advertisement in these

columns:

What business I have I can trace three-quarters of it directly to your

journal.

An agent of the Hinkley Knitting Machine Co., whose invention was

illustrated in these columns some weeks ago, writes:

It is now but ten days since its publication, yet without a single

advertisement in any paper I have been obliged to engage extra

assistance to simply inclose my circulars to parties, who are writing

and even _telegraphing_ for agencies and machines, while many

have traveled long distances to personally engage agencies. The

Superintendent of the Company makes similar _complaints_.

HUNT'S IMPROVED STEAM PACKING PISTON.

Engineers are aware that there are more or less objections to the use

of the ordinary spring pistons, owing to the changing tension of the

springs, the necessity of frequent adjustment, and the impossibility of

the packing rings adapting themselves to the varying pressures of the

steam on the piston. A number of attempts have been made to produce a

self packing or steam expanding piston, which will act always with the

pressure of the steam and the velocity of the engine. The advantages

of such a piston will be readily appreciated by practical engineers,

especially drivers of locomotives, working, as they nearly all do, at a

very high pressure of steam. The general complaint against the several

packings in use on our railroads is, that they "pack too tight,"

and rapidly wear out the rings, while the only remedy has been, the

extremely uncertain one of contracting the openings by which steam is

admitted under the ring, or rings, to expand them. The obvious objection

to such an arrangement is, that it allows the steam to act on the rings

with its full force during slow motion, as when a train is starting,

while if effective under any circumstances, it will be so only at

comparatively high piston speed. The efficacy of such a remedy, if it

possesses any, is in fact inversely as the piston speed.

[Illustration: Fig.1]

Fig. 1 is a perspective of the piston itself, or the "spider," with its

follower and its rings removed, which are shown in Fig. 2. Fig. 3 is a

cross section of another form of the piston, to be presently described,

but which will serve to explain that shown in Figs. 1 and 2. Next to the

core of the spider are two narrow internal rings, A, in Figs. 1 and 3;

surrounding these two outer rings, B, the cross section of which is of

L-form, as seen in Fig. 3. The lips of these outer rings extend to the

whole thickness of the piston. The flange head of the piston, and also

the follower, are turned beveling on their edges to admit the steam

around the annular space thus formed under the rings, B. These spaces

are plainly exhibited at C, in Figs. 2 and 3. Both inner and outer rings

are adjusted to the bore of the cylinder by means of the gibs, D, and

set screws seen in Fig. 1.

[Illustration: Fig.2]

The section, Fig. 3, represents a modification intended for use in

vertical cylinders, if considered necessary. The additional center ring,

E, is intended to prevent leakage through the cut in the expanded ring

and over the face of the unexpanded one, which might occur when the

rings and cylinder should become so worn that the rings, when not

expanded, should collapse and leave the surface of the cylinder. The

rivets, F, shown by the dotted lines, are placed near the cuts in the

L-rings, and are intended to hold the outside and inside rings together

at that point, and prevent any tendency on the part of the latter

to collapse and let steam under that part of the L-rings. Probably,

however, if the packing is properly constructed and adjusted in the

first instance, these devices will be unnecessary. In horizontal

cylinders the weight of the piston, if properly supported on the set

screws and gibs, will accomplish these objects, if the cuts in the

L-rings are placed near the bottom side of the cylinder. The steam

enters the annular space between the beveled edges of the spider flange

and follower and the inner periphery of the overhanging part of the

L-rings, and acts only on that part.

[Illustration: Fig.3]

the patentee, or Sharps, Davis & Bonsall, Salem, Ohio, who will furnish

piston heads to order on receipt of size of cylinder and piston rod.
