Abstract
A spring clutch assembly has an input clutch member (2), an output clutch member (3), and a spring (12) disposed over a coaxial arbor (9). The spring clutch assembly further includes an independently rotatable shaft (16) disposed in a passage extending through the arbor. The shaft includes a splined surface (19) engaged by an axially movable collar (23) having a mating splined surface. The collar is mounted a chamber (20) in the input member, and has extending ears (25) and (26) located in slots (21) and (22) in the chamber sidewall. A cap (30) is fitted to an output end of the shaft and has an arm (38) extending into engagement with an end coil (41). The arm includes a projection which engages a recess in the coil. Axial movement of the collar causes the shaft to turn, relative to the arbor, with the arm forcing the coil spring to compress, disengaging the teaser coils from the output drive surface. Utilizing a shaft assembly for manual clutch disengagement allows the input member to be rotated without rotating the output member.
