Abstract

247,901. Lavaud, D. S. de. Feb. 23, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Variable-speed friction gearing comprises a ball e connecting a cylindrical driving member f to a driven disc a. The speed is varied by moving the member, f axially. The member f may be intermediate between the ball and disc pairs or the disc and ball and be intermediate between member f and a driven shaft in line therewith.
