Title: Improvements in or relating to winches
IPC: B66D1/48
Filed: 1939-11-22
Abstract: 536,688. Winches. BABCOCK & WILCOX Ltd., and MUTCH, R. D. Nov. 22, 1939, No. 30579. [Class 78 (v)] A winch which automatically takes up the slack in the cable holding a water-borne object, when the latter rises on a wave or the winch support falls, comprises a drum 7 mounted freely on a power-shaft 3. Within a recess at one end of the drum is located a cylinder 8 having an internal screw thread 34, bushes 9 giving a slipping support between the cylinder 8 and the interior of the recess. The drum is connected to the cylinder 8 by overlapping rings 14, 15 having abutments between which springs 27 are accommodated, thus giving the cylinder and drum a limited circumferential play' with resilient re-action. Engaging the thread 34 is a tooth 33 carried by a key 35 having an axial traverse in a keyway 32 in a capping end-piece 19 keyed to the shaft 3. A toothed rim 43, engaged by a pinion on a torque motor, is fixed to the opposite end of the drum. When the torque motor is energized the key 35 travels till it comes up against a stop at the inner end of the thread 34 and brings the drum to rest. When an empty hook is being hoisted the main motor drives the shaft 3 in the hoisting direction, with the result that the key 33 tends to move away from the inner stop and allows the torque motor to rotate the drum at a speed controlled by the main motor. When an empty hook is to be lowered the main motor drives the shaft 3 in the lowering direction so that the key 35 comes up against the inner stop and drives the drum, the torque motor being overhauled. When a load is to be hoisted the main motor rotates the shaft 3 in the hoisting. direction. The key 35 then travels till it hits the outer stop of the thread 34, whereupon the springs 27 are compressed and the drive transmitted therethrough to the drum. The load-raising is assisted by the torque motor. When a load is to be lowered the main motor turns the shaft 3 so that the key 35 tends to leave the outer stop and the drum turns under the weight of the load, the torque motor being overhauled. A magnetic brake may be provided on the shaft 3 to maintain the load suspended. In a modification the thread 34 is arranged as a scroll in an end disc and the key 35 moves radially.
