U.S. Patent No. 431,207 (Patented July 1, 1890) by G.L. Gray "Drop Cabinet for Sewing Machines" ?
This must be it... Just for the heck of it, I am printing the patent out and will leave it with the future new owner of this cabinet. (I am not going to keep it, although the treadle is FABULOUS. I may consider another one with a more modern machine, post 1940's, in the future).
@ai6yr I'm sure there are times your foot would get tired, but the great thing about the transition era machines is that you can set them up for treadling or for using electrically.
And it isn't just about sewing machines. There's farm equipment, shears, and other machines that can be run by treadle power. It doesn't make sense to mimic this in gyms, but not actually use the power of treadles in our daily lives.
@ai6yr This is a great thread. I remember my grandma having one of these; the front edge of the treadle could come down on your toes if you weren't careful.
In the film "Fiddler on the Roof," a sewing machine played a part in Motel the tailor's "Miracle of Miracles."
@StumpyTheMutt @rationaldoge Interesting, similar design but different tensioning mechanism.
