Abstract

253,689. Sunderland Forge &. Engineering Co., Ltd., and Howat, I. H. May 14, 1925. Blocks and shoes acting on drums; actuated by springs and by driving-mechanism disengagers.- In reversing mechanism for hoists, lifts, winches, cranes, &c., in which one of two trains of gearing is coupled to the driving shaft 10 when the double cone 12 of a friction clutch is moved in either direction from neutral position by a control lever 24, and in which the movement of the control lever also forces apart the free ends 34 of a band brake on the driven shaft 29 to release this brake, the cone is moved by a pivoted stirrup 15 engaged by trunnions 18 on a nut 19 which is mounted on a threaded shaft 20 rotated directly or indirectly by the control lever 24. The ends 34 of the brake band are forced apart by a double cam 38 mounted on a. shaft 41 which is connected to the lever 24 by an arm 42 and link 43.
