Abstract
731,450. Load-uniting devices. PUTZER, H. Oct. 8, 1952 [Oct. 8, 1951], No. 25229/52. Class 78 (5). A winch drum secured to shaft 2 is driven from member 5 through a resilient friction ring 4 so that no drive occurs when a predetermined torque is exceeded. The device may be combined with a self-sustaining gear, member 1 being screwed on to shaft 2 and member 5 being notched and co-operating with a pawl.
