Abstract: A combination lock assembly for safes in which the combination can be easily reset without dismantling the assembly or changing its original adjustment for smoothness and consistency of tumbler wheel motion. The tumbler wheel and spacing washer components of the assembly are all mounted on a bushing that also includes an end cap. The tumblers and spacers are spring biased by a wave washer so that the drive tumbler, which includes a plurality of angularly spaced holes, presses against the end cap. One of the holes is aligned with a drive stud on the drive cam that is used to position the tumblers. In the event the drive tumbler should receive uneven pressure from the drive studs (e.g., due to improper alignment of the safe's drive spindle), the tumbler wheels and washers are all held together by the bias of the wave washer and are maintained with their engagement surfaces parallel with each other, permitting proper operation without undesirable wear.

Abstract: A locking device for simultaneously locking two adjacent file cabinet drawers in a cabinet housing includes a locking mechanism mounted on a front face of one drawer. When a key is turned to actuate the locking mechanism, a cam, attached to the locking mechanism and positioned generally horizontally in a chamber formed in the first drawer, is rotated through a slot formed in a wall of the first drawer. Continued rotation of the locking mechanism rotates the cam through a slot formed in a mullion provided between the first drawer and an adjacent second drawer and into a slot formed in the second drawer to a generally vertical position for the cam. A central portion of the cam cooperates with the mullion and an end portion of the cam cooperates with the slot in the second drawer to prevent movement of the two drawers in the housing.
Abstract: For use with a quick release mechanism of the quick release lever type for selectively securing and releasing the front wheel of a bicycle relative to the front fork thereof, or the seat post relative to the seat post socket, or the front fork to a vehicle bicycle rack, a lock device including a pivoted blade and controlled by lock engaging means, such as a key, enables or disables the operation of the lever and thus the quick release mechanism by moving the blade between a first position in non-interfering relation with the movement of the quick release lever and a second position in interfering relation therewith.
Abstract: The principal purpose of this invention is to enhance locking and unlocking mechanisms of a padlock by improving structural components which allow the locking core member to be pushed into the lock body in order to trigger the locking mechanism by forcing locking plate and semi-circular sector thereof to be firmly engaged with locking notch located at the end portions of the U-shaped shackle arms. The unlocking mechanism can be triggered by simply rotating the locking core member with a key in one direction for 90 degrees, causing the locking core member and locking semi-circular sector to be disengaged. Therefore, this invention provides a padlock with improved safety features as well as convenience of ease of use.
Abstract: A lock which is adapted to transduce the code from a key by electronic means is constructed to resemble the form and functionality of a conventional mechanical cylinder lock. A main casing houses the bolt, a rotatable thrower or cam for retracting the bolt, an electromechanical release mechanism which normally blocks rotation of the thrower, and a processor to control the release mechanism in response to the detected key code. The electronic reading means are located in association with the keyway of a rotatable barrel in a cylinder unit manufactured as a separate unit from the main casing. The thrower and barrel have respective cooperating mechanical couplings and the main casing and cylinder unit have respective cooperating electrical connectors. The lock is therefore assembled by attaching the cylinder unit to the outside of the main casing, thus establishing a rotary driving connection from the barrel to the thrower and establishing an electrical connection from the key reader to the processor.
