Abstract

830,545. Cable stopper; hoisting loads. LEGRAND, P. Jan. 3, 1957 [Jan. 9, 1956], No. 323/57. Classes 78 (2), 78 (4) and 78 (5). A chain 48 is manually threaded around sprocket 16 by means of cable 47, the chain being pressed into engagement with said sprocket by a grooved roller 36 spring-urged at 42, and pawls 18 engaging ratchets 17 to secure the chain against a load applied to the other end of the chain to thus constitute a chain-locking device A. In use (Fig. 9) the said locking device A is mounted on suspension frame 62 which carries load 54 the chain 48 being threaded through (as above) and locked by locking device A and being swung up and advanced into ship's hold 72 by a driven sprocket 63 mounted on trolley 51. The movement of the load is assisted by a lifting rope 55. Alternatively, the trolley may mount the locking device A and the suspension frame may carry the driven sprocket.
