Hey Bill, I remember those pedal-start washing machine engines; the lady of the house should not have to yank on a rope!
My brother-in-law inherited an acetylene generator, which were used with calcium carbide and water to produce the gas at very low pressures. The same principle was used for miner lamps.
When ever my Grandmother was getting ready to wash clothes, my Dad would start it for her. by the time I came along, in 1947, they had a newer, "plug in" model washer But, of course, the dryer, was a set ot clothesline poles, w/wire strung from pole to pole.
On that welder, I remember that there was a valve, I guess, at the top, with 2 handles sticking out, that were used, to adjust the amount of water needed with the carbide, to produce the gas. My Dad & Granddad, produce to really good welds with that one. Only, they had to clean it out, ever so often and as I said, it had a smell, that stunk to high heaven!
