Abstract
393,812. Clutches ; gearing for starting and stopping machinery. ATELIERS DE ST. PIERRE S. A. R. L., St. Pierre, Bas-Rhin, France. Sept. 15, 1932, No. 25658. Convention date, July 22. [Class 80 (ii).] A winch drum 6 is driven from a wheel 5 loose on the shaft 3 by frictional engagement of an expanding ring 13 within the end portion 12 of the drum when the clutch lever is thrown over so as to turn a sleeve 4 on the shaft and cause axial displacement of the wheel 5 and a cam 11, 11<1>. When the parts 11<1> engage friction surfaces 6<1> on the drum, the cam turns relatively to the wheel and spreads the arms 14, Fig. 3, so as to expand the ring 13. The ring 13 is engaged by a lug 15 on the wheel. The clutch lever operates the member 4 through toggle levers and a spring connection. The clutch is thrown out automatically at end of wind when a nut 21, Fig. 1, travelling along a screwed rod 20 engages a stop 24 on the clutch 16. The nut 21 may be adjusted on the rod 20 by releasing a clamping nut 26 so that the rod can be screwed through the nut 21 without operation of the driving gearing 23, 231.
