  • Patent number: 4958864
    Abstract: There is disclosed a lock to prevent casual theft from dispensers. The lock includes a catch on one wall and a rotatable cam and a release spring with a latch on a second wall. The second wall has a bore for a key slot, an integral mounting post for the release spring, and integral mounting brackets for a retainer plate to hold the release spring and rotatable cam in position. The lock has a rotatable bore cover to inhibit operation of or damage to the lock. The cam is restricted in rotation and has cam profiles which cause the release spring to return to its closed position when the key is released.

  • Patent number: 4956982
    Abstract: Two rings (6, 8) are secured to opposite ends of an elongated chain (4). The rings (6, 8) slidably engage a pair of pivoted semicircular jaws (10, 12). The diameter (D.sub.2) of the smaller ring (8) is sufficiently small to prevent the ring (8) from being slid off of the jaws (10, 12) over their free ends (14). The layer ring (6) freely slides on and off the jaws (10, 12). The free jaw ends (14) have alignable holes (20) for engaging a padlock (22). The device (2) may be used to secure a garment (50, 52) by extending the chain (4) through a sleeve of the garment (50, 52) and locking the jaws (10, 12) onto a chair arm (28), closet pole (34), or other strcture of similar girth. The device (2) may be folded and carried in a small pocket.

  • Patent number: 4957317
    Abstract: A drum lock device is disclosed for an open-head drum which has a flanged lip at the open end with a mating lid therefor. The drum lock device has a lug-type ring closure, a lockable bolt, and a shuttle wrench captively held on the bolt by a cap. The ring closure, which annularly attaches the lid to the lip, has a split therethrough with internally threaded lugs on either side. The shuttle wrench is captively held between the cap and the apertured boss of the bolt, and is slidably positionable between engagement with and disengagement from the lockable bolt. When the shuttle wrench is engaged, the lockable bolt is enabled, and, when the shuttle wrench is disengaged the rotation of the lockable bolt is disabled.

  • Patent number: 4956984
    Abstract: A dual locking latches locking device uses an electronic system or mechanical transmission system to respectively control its own open and close motions. Its dual latches are controlled respectively by two clutch transmission mechanisms. When a user inserts a correct magnetic card in the card reader, its first clutch transmission mechanism is in engagement. When a user inputs a correct code via the keyboard or uses a correct key to unlock it, the second clutch transmission mechanism is all in engagement. At this moment, the user turns the external or internal button and handle at the same time, the lock can be unlocked right away.

  • Patent number: 4953372
    Abstract: Very simple, inexpensive keyless window sash combination code lock has a pivotable cover plate for preventing an intruder from unscrewing the conventional screws for mounting the lock to the sashes. Three combination code dials are slip coupled to associated rotatable pins which pass through the cover plate and an apertured anchor plate. The pins have lugs positioned under the anchor plate to prevent the lock from being opened. When the lugs are positioned within the anchor plate upon installation, the user rotates the dials to create his own custom combination code. The cover plate is then lowered, the dials are rotated and the lock is locked. The code dials are press fitted about the cylindrical locking pins to save manufacturing costs, and the manual sensing of the correct positioning of the code dials by an intruder, to open the lock, is prevented by providing radial dummy recesses in the lower surface of the anchor plate about each locking pin.

  • Patent number: 4953420
    Abstract: A low keylock unit includes an electrical switch unit. A pair of laterally spaced locking levers are pivotally mounted within a rotatable lock tube. The tube extends inwardly into a contact carrier rotatably mounted at the inner end of the switch housing for selective rotation thereof. A rotating switch is coupled to the carrier and selectively engages a fixed contact on a back plate closing the housing. Each lever includes a control leg between a key opening and the pivot and a lock leg between the pivot and the switch unit. A resilient element such as a coil spring compressed between the lock legs or an integral cross between the levers, bears the levers with the lock legs engaging locking grooves on the housing wall to prevent rotation of the tube and the switch unit. A flat key inserted into the lock deflects the legs and pivots the levers outwardly to release the lock legs. If the key is too wide, the control legs move outwardly into the grooves and maintain the locked state.

  • Patent number: 4953900
    Abstract: A locking apparatus includes a generally cylindrical lock body having a pair of spaced apart radially extending lock ring apertures formed therein for accepting a lock ring and a screw aperture formed in an end of the lock body and extending to an adjacent one of the lock ring apertures for threadably accepting a lock screw. The lock ring has a curved central portion attached at opposite ends to a pair generally straight legs adapted to extend into corresponding ones of the lock ring apertures. The lock screw has a head attached to one end of a threaded body adapted to threadably engage the screw aperture and having a cutting edge formed on an opposite end for engaging one of the legs extending into the adjacent one of the lock ring apertures whereby the lock ring is retained by the lock body.

  • Patent number: 4951489
    Abstract: A key holder which has a pair of shells for enclosing the keys which are connected together by a spring-loaded locking hinge. The keys are connected to the shells by at least one arm attached to one of the shells. The keys can be stacked on top of each other inside the key holder. The spring-loaded locking hinge generally holds the shells in a closed position relative to each other. This is accomplished by a knob on one part of the hinge which engages with a notch on another part inside the hinge. A spring kept in torsion and compression tends to urge the shells open so that when a button on the end of the hinge is pressed, the knob disengages the notch and the spring causes the shells to open.

  • Patent number: 4952228
    Abstract: A push-button padlock having a swivel-only shackle, the free end of which is receivingly engaged by a sleeve that is reciprocable into the padlock body housing upon actuation of a thumb latch member projecting through the housing, preferably through a hole in the front face. The shackle is an inverted J-shaped shackle with the longer end entrained in the padlock body where it engages a latching mechanism which includes the thumb latch and shackle sleeve members. The thumb latch is preferably of breakaway construction and the sleeve may be rotatable. A locking mechanism of any desired type to selectively lock and unlock the latching mechanism may be employed. One preferred locking mechanism is of push-button type, and another preferred locking mechanism is a key lock mechanism, both of which are operative to selectively lock and unlock the latching mechanism that may be employed.

  • Patent number: 4949561
    Abstract: A device for securing the steering wheel of a vehicle has a lock housing with an axial bore for receiving a telescoping rod. A pair of legs extend from the housing at an acute angle relative to the axis and to one another. The rod extends from the bore in the opposite direction, and hook members are formed on each leg and the rod for engaging opposite sides of the steering wheel. The hook member on the rod, which is preferably an open, fan shaped jaw, is spaced a distance from the outer end of the rod, so that when the device is mounted on the steering wheel, the rod projects outwardly from the steering wheel and inhibits it from being turned.
