ABSTRACT:
A disengage mechanism for a gear drive including rotatable drive and driven members with one of the members having first splines. A drive actuator having second splines and being connected to rotate with one of the members and axially movable with respect thereto between first and second positions. In the first position the first and second splines are engaged and the drive and driven members are connected to rotate together and in the second position the splines are disengaged and the drive and driven members are disconnected. First means are provided for moving the drive actuator to the first position and second means move the actuator to the second position. The first means include a spring which constantly urges the drive actuator to the first position and the second means comprises a rotatable cam member which positively engages the drive actuator to move it to the second position. Means are provided for locking the cam member to the housing of the disengage mechanism and indicia are provided so that an operator of the device will know whether the cam member is either in its first position or its second position. Additionally, the cam member is provided with a detent within which a cam follower resides in the first position of the cam member which prevents accidental movement of the drive actuator from its first position.
