AMERICAN WORKSHOPS.

An interesting paper on some of the leading American workshops was

lately read before the members of the Manchester Association of

Engineers on Saturday by Mr. Hans Renold. After expressing his opinion

that the English people did not sufficiently look about them or try to

understand what other nations were doing, Mr. Renold stated that he

had visited that portion of America known as New England, and the

works he had inspected were among the best in the United States. Among

the many special features he had noticed he mentioned that in a Boston

establishment where milling machine cutters were made he had found

that £1 spent in wages produced as much as £30 to £40 worth of goods,

the cutters being made at the rate of about sixty-four per hour by

about a dozen men. Another noticeable feature was the exceptional care

taken in storing tools in American workshops. These, in fact, were

treated as if they were worth their weight in gold; they were stored

in safes much in the same manner as we in England stored our money. He

was, however, impressed by the fact that the mere understanding of the

method of American working would not enable them to do likewise in

England, because the American workmen had gone through a special

training, and a similar training would be necessary to enable English

workmen to adapt themselves to American machines. One very noticeable

feature in American engineering shops which he visited was that all

the machine men and turners were seated on blocks or stools at their

machines, and the question naturally arose in his mind what would

English engineers say if such a practice were adopted in their shops.

In other ways he was also struck by the special attention devoted to

the comfort of the workmen, and he was much impressed by the healthy

condition of the emery polishing shops as compared with similar shops

in this country. In England these shops in most cases were simply

deathtraps to the workmen, and he urged that the superior method of

ventilation carried out in the States should be adopted in this

country by introducing a fan to each wheel to take away the particles,

etc., which were so injurious. One very special feature in the United

States was that works were devoted to the manufacture of one

particular article to an almost inconceivable extent, and that heavy

machine tools complete and ready to be dispatched were kept in stock

in large numbers. American enterprise was not hampered as it too

frequently was in England by want of capital; while in England we were

ready to put our savings in South American railways or fictitious gold

mines, but very chary about investing capital which would assist an

engineer in bringing out an honest improvement, in America, on the

other hand, it was a common practice among the best firms to invest

their savings over and over again in their works, which were thus kept

in a high state of perfection.

The above paper came in for some pretty severe criticism. Mr. John

Craven remarked that although Mr. Renold had gone over a wide field of

subjects, he had practically confined his remarks to Messrs. Brown &

Sharpe's establishment, and while he (Mr. Craven) was ready to admit

that so far as high class work and sanitary arrangements were

concerned, Messrs. Brown & Sharpe's were a model, they could not be

put forward as representative of American establishments generally. As

a matter of fact, many of the American workshops were not as good as a

large number of similar workshops in Manchester. Mr. Renold had

referred to the extensive use of gear cutters in the United States,

but he might point out that it was in Manchester that the milling

machine was first made. Mr. Samuel Dixon said he had certainly come to

the conclusion that no better work was done in America than could be

and was being done in this country; while as regards the enormous

production of milling cutters, that was simply an example of what

could be done where large firms devoted themselves to the production

of one specialty. With regard to the statement made by Mr. Renold that

the American thread was preferable to the Whitworth thread, he might

say he entirely disagreed with such a conclusion, and he might add

that after visiting a variety of Continental and American workshops he

should certainly not, if he were called upon to award the palm of

superiority in workmanship, go across the Atlantic for that purpose.

Mr. J. Nasmith remarked that whether English engineers were the

inventors of the milling machine or not, it must be admitted that it

was through this type of cutter being taken up by the Americans that

milling had become the success it was at the present time. English

engineers were very conservative, and it was only through the pressure

of circumstances that milling machines came into general use in this

country. When American inventions were brought to England they were

generally improved to the highest degree, but he thought the chief

fault of both American and Continental engineers was what one might

call "over-refinement;" there was such a thing as over-finishing an

object and overdoing it. If, however, American machinery was so much

superior to what we had in this country, as asserted by the reader of

the paper, how was it that cotton machinery, with all its intricacies,

could be sent to the United States, in the face of American

manufacturers, even though the cost was increased from 40 to 60 per

cent.? At the present time it was possible for English machinists to

secure contracts for the whole of the machinery in an American mill,

and inclusive of freight charges and high tariff, deliver and erect it

in America at a lower cost than American engineers with all the

advantages of their immeasurably superior tools were able to do.

Another speaker, Mr. Barstow, ridiculed the idea that the Americans

could be so pre-eminent in the manufacture of emery wheels as might be

inferred from Mr. Renold, when they had before them the fact that from

the neighborhood of Manchester thousands of emery wheels were every

year exported to the United States.
