Abstract

140,377. Prat, G. J. March 19, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Variable-speed gearing.-Gears a, c, Fig. 2, on driving and driven shafts b, d present annular surfaces of semicircular section to connecting- gears e, which are adapted to be tilted to vary the speed of transmission. Friction or toothed gearing may be used. In the former case, the gears e may have pneumatic tyres. Spindles i, Fig. 3, supporting the gears e are adapted to be turned together by a rack l. It is stated that, if springs tend to turn the spindles i in one direction, the gearing becomes automatically variable with the load.
