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 is operated by depressing a manual actuator portion thereof in an opening in the lock casing and the shift member includes a cam surface which moves the sleeves out of coupling engagement with the dials responsive to depression of the manual actuator portion by reaction of the shift member with an internal surface of the lock casing.

Abstract: A combination lock of the dial and sleeve type has a scramble feature enabling a hasp to be engaged with a latch of the lock even when the dials and sleeves are not on-combination, by independent movement of the latch relative to manual actuating means of the lock. When the hasp is engaged, it supports the latch in a position in which the latch is adapted to engage a blocking element that prevents the latch from being moved out of its hasp-engaging position independently of the manual actuator. This arrangement effectively prevents the lock from being forced open when the hasp is engaged.

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.
