Abstract

169,210. Stack, G. F. May 20, 1920. Variable-speed friction gearing.-In gearing of the kind in which the frictional engaging pressure is varied as required, the gear is so constructed that the fulcrum of a lever is moved as the speed is changed. A disc 2 is pressed against a roller 1 by a lever 13 loaded by a spring 14 and tending to turn about a fulcrum 16. The roller 1 is connected by links 4, 17 and a lever 3 to the fulcrum 16, so that the roller and fulcrum move together. The fulcrum 16 is supported by a plate 15 having a recess 24 corresponding to disengaged drive. An arrangement for adjusting the plate 15 automatically is described. If, owing to wear, the lever 13 takes the position shown in Fig. 6, changing gear causes the lever 13 to oscillate. A pawl 21 on the lever 13 acting on a ratchet 22 then feeds the plate 15 to a parallel position.
