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.
