ABSTRACT:
Difficulties in positively engaging and disengaging helical spring clutch mechanisms are avoided in a construction including a driven shaft (10) with a gear (18) rotatably mounted on the shaft (10). A helical spring (40) is disposed about part (24) of the gear (18) and the driving shaft (12) and a reaction collar (28) is located adjacent to the spring (40) and is splined to the driving shaft (12). A friction collar (52) is engagable with the helical spring (28) and is carried by the driving shaft (10). Ball actuators (62, 64) are provided for selectively engaging the friction collar (52) with the helical spring (40) thereby causing the spring (40) to engage the reaction collar (28) and rotate with the driving shaft (12) to drive the gear (18). r
