Combination locks
First Claim
1. A combination lock including a plurality of combination elements disposed on a common axis in a casing for axial movement in unison out of coupling engagement with cooperating combination components in order to change the combination of the lock, a shift member for moving said elements axially, said shift member including an actuator portion extending through an opening in said casing and means providing a camming action between said shift member and said casing for causing said shift member to move said elements axially responsive to movement of said actuator portion in said opening, said means including a lock surface extending obliquely to said axis and the shift member being adapted to move along said surface to provide the camming action.

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 extending through an opening in the face plate of the lock which opening extends obliquely to the axis of the sleeves and movement of the actuator in the opening effects axial movement of the sleeves by a camming action effected against an obliquely extending surface of the opening.
