Abstract
1501309 Friction clutches MARQUETTE METAL PRODUCTS CO 12 July 1976 28927/76 Heading F2C In a normally engaged helical spring clutch wherein a helical spring 16 frictionally engages clutch drums 20, 32 fast with a shaft 26 and gear 35, the ends 42, 44 of the spring 16 are bent radially outwardly to engage arcuate slots 50, 52 in the ends of a control sleeve 18 which is held by a detent to disengage the clutch. The arrangement provides a disengageable one-way drive irrespective of which drum acts as the driving element. When the detent holds the control sleeve 18 the projecting spring end associated with the driving drum abuts the end of its arcuate slot and expands the spring for clutch disengagement. As shown, when the clutch is disengaged the driven drum is permitted to coast. In Figs. 5 and 6 (not shown), one or both ends of the spring have a reduced internal diameter in the relaxed state and, when assembled, grip the driven drum sufficiently tightly to brake the latter when the clutch is disengaged.
