Those Lincolns were called coffee grinders, you still see em at auctions and estate sales, the first sheet metal shop I worked at had an over head jack shaft, EVERYTHING ran off that shaft, the one half inch by ten foot shear the 12 foot press break that would put a 90 in 12 feet of 1/4' mild steel, you might have to jump on the pedal a couple times but it would do it.
all the drill presses, everything but the welders,( I remember when they came around with the first wire welders it was ten years before anybody trusted the welds they made) IIRC the main motor was about 15 or 20 HP and it was a huge old thing, it had an open frame and had lots of oiling points, that was the apprentices job (me).
I also got to fix belts, at least two a day broke or came apart, nothing was shut down, i just got the belt length, put on the laces, put it over the shafts and fed it on the pulleys, there were NO guards anywhere, a contemporary OSHA inspector would have a stroke and die right on the spot.
I remember a furniture shop we used to do a lot of blow pipe work in had and actual stationary steam engine that ran the whole plant, the plant had about five floors, you want to talk about a LOT of jack shafts and belts, a lot of the jack shaft bearings were just greased wood pillow blocks.
It mad a lot of sense for them because they could run the plant in saw dust, shavings and scrap they made, the engine even had a dynamo on one end that made electricity for the plant too. I got caught a lot of times just standing there watching that engine run.
