Nowadays, when they want to disconnect the waterwheels
the engineer sends a boy to pull the clutches. The boy proceeds to a part
of the shop directly over the wheel-pits and proceeds leisurely to "unscrew"
a large polished handwheel, whistling merrily the while such tunes as
"Yankee Doodle" or "The Little Birch Canoe," but 30 years ago large friction
clutches were not plentiful in small town shops and as the power from
the wheels was delivered through a 30-in. three-ply belt...
Johnnie was one of the most inventive little cubs that
ever grew up in a machine shop. He would much rather spend a day in inventing
ways to do something that nobody wanted done than to devote an hour or
so to doing something useful. This does not mean that Johnnie was lazy
or sought to shirk his share of whatever was doing. He was a bright, active
lad, with an aptitude for mechanics...
Standing in one corner, and covered with the rust and
dirt of ages, was another relic--the governor from a remote predecessor
of the shining, business-like, 200-hp. Wheelock engine that was now running
the factory. It was a tall ungainly thing, with "fly-balls" that would
make very creditable shot for a trench mortar in a modern war, but Johnnie
couldn't bear to see it standing there in the corner just going to waste.
After a week of feverish activity with much running back
and forth between the machine and blacksmith shops, Johnnie invited us
out to the blacksmith shop....
Because of my proficiency in scraping and polishing, acquired
during my eight months' experience at Baldwin's upon handrail parts for
locomotives (of which kind of work I had become very tired), the first
job handed me in my next place of employment was the scraping and polishing
of a lot of change gears for lathes. This was in the shop of Bement &
Dougherty, builders of heavy machine tools, located on Callowhill St.
in Philadelphia.
The gears were what are called "web" gears; that is, they
had no spokes, even in the largest diameters...
The lathe on which the polishing was done was located
in a dark corner of the shop so that I was obliged to light the gas (a
welcome improvement over the old whale-oil lamps I had known)...
