Abstract
Concentric driving and driven clutch rings have teeth in a common radial plane on one end of the rings. The clutch rings are normally coupled together by a coupler ring having teeth engaging the teeth of both clutch rings, this engagement being maintained by an axial clamp bolt. In the event of dangerous overspeed the clamp bolt is broken and the coupler ring is disengaged from the clutch rings by an explosive charge acting on an axial piston. The explosive charge is detonated by a firing pin actuated by a steel ball impelled by centrifugal force. The ball is retained by a magnet until centrifugal force exceeds the magnetic force holding the ball.
