Abstract

809,008. Taking-up slack. RUSHWORTH, D. Aug. 2, 1957 [May 5, 1956], No. 13963/56. Class 78 (2). The slack of cable A which supplies electricity or air to reciprocating coal cutter D from point B, is taken up by pulley C, the cable passing around pulley C affixed to a drum G, which drum is biased to move to the right by rope E, which is tensioned by spring-drum (or power-driven winch) F.
