Goodell Pratt made and sold two tables that included a flywheel and a treadle or pedal (depending on model) designed to power small machines. The 120 was more of an all purpose table that could be used for almost any kind of small machine such as a lathe, scroll saw or even a drill press. The 121 was specifically designed to power the 125 bench lathe but was not long enough to handle the 494 bench lathe.
Both tables were very well built and substantial and weighed 115 pounds for the 120 which had a wood top and 160 pounds for the 121 which had a cast iron top and a 3 step flywheel that matched the headstock of the 125 bench lathe.
The following catalog cuts from 1922 give the details and prices. Actual pictures of these two tables can be found in the links provided below to the 125 lathe page and the 700 precision lathe page.
