Abstract

172,217. Williams, E. Nov. 30, 1920. Drivirvg and feed devices.-In a controlling- mechanism, for the change-speed gearing of grinding-lathe headstocks, of the type described in Specification 6038/14 the hollow driving-shaft a of the headstock encloses a main clutch-operating rod b actuated by a cam d on a shaft e having a pair of arms f secured to a parallel shaft g. Each of the gear levers h is movable in a vertical plane to bring a spring-controlled thrust-piece i into contact with the shaft g to rotate the cam d and disengage the clutch. This downward movement releases the operating-lever from a gate i whereupon further movement in an horizontal plane moves a fork (not shown) along the shaft e to effect the gear change. A brake lever m coacting with a collar on the shaft a is actuated by the shaft g so that the operation of releasing the clutch is accompanied by a braking action on the shaft.
