Abstract

158,659. Wellman Smith Owen Engineering Corporation, and Jardine, J. Nov. 7, 1919. Jib cranes.-Horizontal traverse of the load during luffing is secured by passing the hoisting- rope 12 over a pulley 2a which slides in the jibhead and is controlled by a rope 1 passing over a jib-head sheave 4 and over a cam or lever 3 on the crane post. The cam 3 is fixed to a pulley 10 over which the luffing-rope 9 passes, so that as the jib is luffed the cam is rotated and the rope 1 paid out or taken in to control the load sheave 2a. the pulley 10 may be of cam shape, and the member 3 may be circular, or both pulley 10 and member 3 may be circular.
