Magnetic clutch and brake assembly

摘要

A positive acting magnetic clutch and brake assembly characterized by including a movable, magnetic member provided with two sets of detents arranged respectively on its opposing outer surfaces. The member is alternately shiftable into either a brake position, in engagement with a braking post mounted to engage one of the sets of detents, or to a drive position in which a reciprocally mounted mechanical dog is engaged with the other set of detents in a non-slip driving coupling between the magnetic member and a clutch assembly. A reciprocal mounting arrangement for the dog enables the magnetic member to be moved into driving contact with the clutch assembly before the dog becomes positively engaged with any of the detents on the magnetic member.
