Abstract

818,266. Variable-speed chain gearing RESILION CO. Ltd. Nov. 22, 1957 [Nov. 24, 1956], No. 36021/56. Class 80 (2). In variable-speed gearing of the kind in which changes are obtained by shifting the chain from one to another of different size sprockets, a main sleeve e secured to a fixed bracket f of the gear is internally threaded at m to receive an adjustable stop sleeve n which is abutted by a spindle d sliding in the main sleeve e and carrying the support a for the jockey sprockets, the outermost position of the spindle being determined by the adjustment of the stopsleeve. The stop-sleeve n is chambered to provide a run for the speed-changing control chain and has a slot q wherein the chain runs and prevents turning of the sleeve n from its adjusted position. A second slot r having a width of an inner chain link may be provided to enable the gear to be locked in any one ratio. The spindle d is urged inwardly and rotated to take up the slack in the chain in a known manner by a helical spring j.
