ABSTRACT:
A torque transmitting coupling of a type having a housing with an opening therein which has a plurality of longitudinal splines along one part thereof and having another portion thereof which is circular. A sleeve is rotatably disposed within the circular part of the opening in the housing and this sleeve has a plurality of splines around the inner periphery thereof. The sleeve has a pin attached thereto which extends through a radial slot in the housing. A collar is slideably received on the exterior of the housing and is slideably movable in a longitudinal direction only and is biased to one position. Camming means are formed in the collar for moving the pin attached to the splined sleeve and thereby for rotating the splined sleeve from a first position which locks a shaft into the coupling to a second position which unlocks the shaft to be used in conjunction with the coupling. A free spinning shield is disposed around the housing. Selective longitudinal movement of the shield locks or unlocks the coupling by moving the collar. A mechanism for moving the shield and thereby for locking or unlocking the coupling is also provided.
