ABSTRACT:
An improved transmission shift mechanism which incorporates both a combined synchronizing clutch and a positive engagement system for coupling and decoupling gear elements within a transmission frame. The synchronizing clutch mechanism has a plurality of circumferentially spaced latch members which are radially displaceable for frictional circumferential engagement with the inner walls of a gear member having a central bore opening. The positive engagement system is a locking unit which includes circumferentially spaced spherical elements which are also radially reciprocal for seating within corresponding recesses within the bore of the gears. The frictional engagement members and the positive locking ball elements are cooperatively actuated through contoured cam surface elements which are longitudinally displaceable within the sliding member responsive to manual operation of an extension rod in the longitudinal direction.
