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.

Abstract: A combination padlock has a plurality of permutation tumblers mounted on a ember shiftable in a cavity in the body of the lock to effect a change in combination. Limit means cooperate with the tumblers for preventing the member from being shifted except when the tumblers are set in the correct combination. The member can be shifted in response to movement of the shackle of the padlock, but only when the lock is open. The bolt of the padlock and the shackle are designed to permit the tumblers to be scrambled when the lock is open, thus concealing the correct combination from unauthorized persons, and preventing the combination from being changed while the lock is open.

Abstract: A drawbolt for the mating shells of a container has a latch whose spaced e walls are provided with open slots that receive a transverse cross-bar on one end of a loop whose other end is engageable behind a hasp on one of the shells. Outwardly directed lugs on the side walls are received in aligned apertures in spaced guide walls of a frame, such walls having edges defining aligned peripheral cam surfaces which, together with the closed end of the slots in the latch, capture the cross-bar of the loop and establish a pivotal connection between the latch and the loop. By attaching the frame to a plate adapted to be mounted on the other of the shells, the apertures in the guide walls are closed by the plate. The free ends of a pair of upstanding tabs on the plate cooperate with the closed ends of the apertures in capturing the lugs on the latch thus establishing a pivotal connection between the latch and the frame.

Abstract: A latching device for releasibly locking together the two zipper pulls on a ouble zipper type case includes a frame, a rotatable key barrel projecting from the frame for being received in respective openings in the zipper pulls, a latch member pivotally connected to the frame for movement between a lowered position overlying the frame and a raised position, the latch member having an opening therein for receiving the end of the key barrel when the latch member is in lowered position, and a key-actuatable bolt member supported below the key barrel for sliding movement between the locking and unlocking positions to releasibly lock the latch member in lowered position. The frame is mounted at one end of an elongated mounting plate having its other end constructed to engage a rigid reinforcing member of the case.

Abstract: In a latching device having a first push member to be depressed to releasy engage a hasp and a second push member cooperable with the first push member to be depressed to release the hasp, the cooperable parts of the push members comprise flat plate portions which are disposed in and movable in the same plane.

Abstract: In a latching device cooperable with a pair of spaced hasps, a pair of spaced latch mechanisms which are biased toward unlatching condition are held in latching condition by respective longitudinally movable control members. A manually rotatable control knob located intermediate the latch mechanisms and cooperable with the control members is movable to a release position which permits the latch mechanisms to be urged into unlatching condition, the latch mechanisms being returnable manually to latching condition. Combination locking means is provided for releasably locking the latch mechanisms in latching condition.

Abstract: A multiple dial type combination lock in a luggage case handle stud employs an elongated, longitudinally movable puller formed to engage a cooperable hasp and having longitudinally spaced slots receiving dials. The dials, which are keyed for rotation with associated sleeve means by interfitting teeth, are cooperable with respective lugs on the puller for blocking movement of the puller from latching position when the dials are off combination. Each sleeve means has a missing tooth portion for receiving the respective lug on the puller when the dials are on combination, thereby permitting movement of the puller between latching and unlatching positions, the dials being shifted longitudinally with the puller during this motion. In the preferred embodiment, the opening combination may be set to a combination of one's own choice.
