Abstract

2620. Lockfaw, J. A. Feb. 2. Pulley-blocks.-A sheave A is mounted to turn on a fixed axle B engaged by side members each formed in two parts C, C'. The side members are provided with grooves along their edges engaged by U-shaped bolts D which pass through the cross-piece E and are secured by nuts. The bolts D also lie in grooves in the axle B and secure the axle from rotation. Oilchannels C<2> are provided in the side cheeks and in the axle.
