this is this cool gear less gear box my boss has sitting around. it came off of aome mistery thing he scraped a few years ago, and i don't know whay it came off. anyway i took a look at it when i scraped it, and from what i can see it is a really eraly hydrostatic transmition. whell it not a trany but you know. in the pics you can see a canvass best with blocks of wood with tapered ends bolted to it. the two pulles are tapered, and when you crank the handle one pully would open and the other close up. witch would make the belt eath ride up or fall down in. makeing it change the gear ratio. i though it was really cool, but had no room to save it from the scraper.
