Abstract
A system for transmitting motion between a driving component and a driven component includes a torque release clutch for transmitting motion between the components until a predetermined amount of force is required to do so, whereupon the clutch releases. The clutch includes a pair of relatively movable members, at least one ball, and an expandable ring. The ball has one position wherein the ball is in engaged or interfering relationship between the pair of members whereby movement of one member effects movement of the other member. The ball has another position wherein the ball is out of interfering relationship with or disengaged from at least one movable member. The expandable ring is mounted on one of the movable members and is engageable with the ball to hold the ball in engaged position until a force applied to the ball exceeds a predetermined amount, whereupon the ring is forced to expand and allow the ball to move to the disengaged position. A resetting mechanism is provided to move the ball back to the engaged position.
