In the winter of ’72-3 I had a call from my friend, J. C. Hoadley,
accompanied by Mr. Charles H. Waters, manager of the Clinton Wire Cloth
Company. Mr. Waters wished to obtain one of our engines. I told him I
was very sorry, but we should not be able to make one for him. I then
explained our situation. Our lease would expire in a month or two, and
could not be renewed, and we had made arrangements then to close our
business, had sold all our tools deliverable before that date, were
rushing two engines to completion, but absolutely could not undertake
another order.
“Never mind,” said he, “one of your engines I must have.” He then told
me that he was about to introduce a new feature in weaving wire cloth.
This was then woven in various narrow widths, according to customers’
orders, having a selvage on each side. He had satisfied himself that
this latter was unnecessary. The wire, being bent in weaving, had no
tendency to ravel, and he had planned a loom to weave the cloth seven
feet in width, and slit it up into narrow widths as required. In this
loom the shuttle alone would weigh a hundred and fifty pounds, besides
the great weight of wire it would carry; it had to be thrown nearly
twelve feet, and he wanted to make as many picks per minute as any
narrow loom could do. In order to make these throws uniformly, he
required absolutely uniform motion. From a careful study of slow-moving
variable cut-off engines, he had satisfied himself that none of them
could give him the uniformity of motion he needed. They were driven by
a succession of violent punches, these excessive amounts of force at
the commencement of each stroke were absorbed by the fly-wheel, the
velocity of which had to be increased to do it, and at the end of the
stroke its velocity had to be reduced in the same degree, to supply
the total failure of the force of the steam. This involved a variation
of speed which in ordinary business would not be regarded, but which
would ruin the action of this new loom. In the high speed of my engine,
and the action of the reciprocating fly-wheel, which compensated the
inequalities of the steam pressure without affecting the uniformity of
the speed, he found just what he needed, and that engine he must have.
I was astonished at the man’s penetration.

I was able to get from our landlord and purchasers of our tools the
necessary extension of time, and made the engine for him. It and the
loom were each a complete success. Mr. Waters told me long after that
he never observed a single variation from exact uniformity of motion,
without which his loom would have had to be abandoned.
I had one day the pleasure of meeting there the president of the
Lancaster mills, the only other great industry of Clinton, who had come
over expressly to examine the running of our engine. Before he left he
said to me that the engine certainly presented a remarkable advance in
steam engineering.
