Abstract
A clutch particularly suitable for machine drives in agricultural implements including a clutch hub, a clutch sleeve, and spring-loaded dog members operative to engage and disengage within tapered recesses in said clutch sleeve for controlling torque transmission through the clutch. The recesses are formed with a circumferential dimension large enough to accommodate therein movable control members together with engagement heads of the dog members. The control members cooperate with the dog members within the recesses to effect disengagement of the clutch when a maximum torque is exceeded and to automatically effect re-engagement of the clutch upon achievement of a nominal speed whereupon the dog members, which are spring-loaded in the clutch hub, may automatically re-engage within the recesses.
