Power is transmitted from the driving to the driven link by balls 3 which are gripped between cam 1 and ratchet wheel 2. Either cam 1 or wheel 2 may serve as the driving member. Cam 1 rotates about fixed axis A and has circular recesses a. Wheel 2 rotates freely about axis A and has circular recesses b. The balls roll by gravity between the surfaces of cam 1 and wheel 2. The driving member oscillates and the driven member rotates intermittently in one direction.
