A CLUTCH

摘要

A clutch comprising an input shaft driving a cam positioned against a follower adapted to engage an output shaft, the follower being displaceable against biasing means by the cam to engage the output shaft, whereby rotation of the input shaft and cam in either direction causes the follower to transfer drive to the output shaft and when the input shaft is stationary the biasing means displaces the follower away from the output shaft to disconnect drive to the output shaft.
