Abstract
A dial and sleeve type combination lock is provided with a shift member to move the sleeves out of coupling engagement with the dials for changing the combination of the lock. The shift member includes a manual actuator portion extending through an opening in the face plate of the lock. Axial movement of the sleeves out of coupling engagement with the respective dials is effected through a camming action by moving the manual actuator portion in the opening axially in the opposite direction to the direction of movement of the sleeves.
