Abstract
An automatic roller-type hub clutch is provided with a manual device operable to override the automatic mechanism to prevent free wheeling due to overrun. An improved resilient coupling is provided for the manual device designed to translate rotational movement from a rotatable selector to a camming device and to provide a built-in self energizing action in both an engaging and disengaging direction. The resilient coupling disclosed is a coiled torsional spring having one end connected to the rotatable selector and the opposite end connected to the camming device. In operation, the rotatable selector is rotated in opposite directions to wind and unwind the spring causing the camming device to rotate with the rotatable selector to axially move a slidable clutch member into engagement with a fixed clutch member.
