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.

Abstract: A combination lock in which an actuator is movable in a predetermined dirion from a rest position to an unlocking position to unlock the lock and is further movable in the predetermined direction beyond the unlocking position to a combination-changing position to permit the combination to be changed. Movement of the actuator to the unlocking position can only occur when combination dials and sleeves coupled thereto are "on-combination". In the combination-changing position of the actuator, the sleeves are uncoupled from the dials. A stop mechanism is normally effective to prevent movement of the actuator to the combination-changing position and is rendered ineffective by depressing a plunger. The same stop mechanism holds the actuator at the combination-changing position during changing of the combination.

Abstract: A lock comprising a bolt slidable into an operative position and from there rotatable into a locked position in which pins projecting from the bolt prevent it from sliding: locking members are rotatable about axes orthogonal to the axis of the bolt into positions where they interfere with rotation of the pins, and prevent the bolt from being rotated out of the locked position, unless the locking members are properly positioned about their axes.

Abstract: A combination lock includes a plurality of setting wheels each having a sliding pin and each having a plurality of numerals marked on a peripheral surface. When the setting wheels are rotated to a predetermined combination of numerals, the sliding pins form a linear array. A manually operated plunger urges a cam surface against a first end of the linear array of sliding pins and transmits a force through the sliding pins causing a second end of the linear array to bear against a latch bar thus opening the combination lock.

Abstract: A combination lock which employs a plurality of dials and respective sleeve eans for each dial has a pivotally mounted bolt member related to the sleeve means so that the bolt member may be pivoted to respective "on combination" and "off combination" positions. A latch member cooperable with the bolt member is mounted for sliding movement in a direction which is perpendicular to the longitudinal axis of the shaft upon which the dials and their respective sleeve means are mounted. Cooperable means are provided by the bolt member and the latch member to block movement of the latch member toward release position when the lock is "off combination". The latch member is provided with means to allow by-passing the bolt member and movement of the latch member to release position when the lock is "on combination". The combination lock is particularly suited for briefcases or the like.
