Abstract

256,284. Brown, W. S. F., and Maina, J. Feb. 5, 1925. Blocks and shoes acting on drums; fluid-pressure.-Variable -speed gearing comprises -epicyclic trains entrained by applying brakes by hydraulic means. Each brake drum is grooved externally and is adapted to be gripped by a pair of pivoted brake shoes 16, Fig. 3, when oil under pressure is admitted to a cylinder 18.
