ABSTRACT:
A combination lock for luggage, for example, which may be surface mounted. ial gears and cooperable gears have separate axes parallel to the thickness of the lock. In the on-combination position, hubs of the cooperable gears are aligned with openings in a slide that is moved relative to the hubs to permit an actuator to move a latch to its open position. The latch may also be moved to its open position by a hasp, even when the combination is scrambled. A shifter, which has an operator accessible at the face of the lock only when the hasp has been released by the latch, moves the slide and the cooperable gears as a unit, to disengage the cooperable gears from the dial gears for changing the combination.
