I fitted up these standards, both surface plates and straight edges,
with their edges scraped also to true planes and all their angles
absolute right angles. For this and other purposes I made two angle
plates, each face 8 inches square, with diagonal ribs. These were
scraped so that when the two were set on a surface plate, either
surface of one would come in complete contact with either surface of
the other, and also when one or the other was set on its edges. This
angle plate also is shown.
For our screw-thread work I made a pair of steel 60-degree standards,
the truth of which was demonstrated as follows: The outside gauge being
set up on a surface plate, the inside triangular block set on the
surface plate passed through the former in exact contact, whichever
angle was up and whichever side was presented. From the cylindrical
gauges of Smith & Coventry I made flat inside and outside gauges of
steel with faces hardened, reserving the former for reference only.
I had wondered why this was not done in England. Presume they have
learned the importance of it long ago.
We could not advertise--the fact is I was ashamed to; but we had as
many orders as we could take with our very limited means of production.
Indeed, we had frequent applications which called for engines too
large for us to consider them. We had some applications from parties
who were short of power, and on measuring their engines with the
indicator always found that we could supply their requirements by
putting in smaller engines. In one case I remember we put in an engine
of just one half the size, and requiring but one quarter the weight of
fly-wheel, of the one taken out, and gave them all the additional power
they wanted, and more uniform motion. This would seem an extravagant
statement were not its reasonableness proved by the experience of
makers of high-speed engines generally. Sometimes the indicator showed
ludicrous losses of pressure between boiler and engine.
On account of his familiarity with the requirements of more exact
construction, I made Mr. Goodfellow my foreman after he had been with
me a short time, and he proved to be the very man for the position.
He made all my engines in Harlem and afterwards in Newark, and I was
largely indebted to him for my success.
Before the close of our first year Mr. Smith proposed that our business
be transferred to a company, to which he would pay in a little
additional money, in consideration of which, and of his previous
advances to the business, he demanded a controlling interest in the
stock. I did not like the idea, but Mr. Hope and Mr. Allen favored it,
and I consented. So the company was incorporated. Mr. Smith was made
its president, and one of his sons was made secretary and treasurer. He
transferred to this son and also to another one qualifying shares of
his stock, and both were added to the board of directors, that making
six of us. The admirable way in which this machinery worked will appear
by and by.
