  • Patent number: 5735147
    Abstract: An apparatus is adapted to prevent the theft of a wheeled vehicle having air brakes (e.g., large trucks and buses). A brake valve is selectively actuated by linear movement of an exposed knob that is located adjacent a supporting structure in the cab, and a valve housing is mounted behind the supporting structure. A new structural base is permanently connected to the valve housing in an exposed position in the vehicle's cab. The base is normally accessible to the driver at all times, but it is thin enough so that it will not interfere with normal push/pull movement of the valve's knob. A rigid and generally hollow cover is adapted to be selectively suspended over and in contact with the structural base. The cover is sufficiently deep as to envelop the valve's knob in order to conceal it and render it inaccessible when the cover is suspended over the base. The cover is selectively removable from the base so as to permit the driver to remove the cover and thereby have access to the knob.

  • Patent number: 5701772
    Abstract: A multishaft combination lock includes a lock body, an alignment sleeve, and a detachable pin. The alignment sleeve has a hole and is rotatably coupled to the lock body to provide access into the lock body. The alignment sleeve has an angled cutout at a first end, with the alignment of the cutout being adjusted by rotating the alignment sleeve. The detachable pin has a floating bushing that can be misaligned with the principle axis of the detachable pin. To lock the multishaft combination lock, the lock body is fitted to the detachable pin through the hole of the alignment sleeve with the floating bushing misaligned with the angled cutout. When the detachable pin is fully inserted into the lock body, the floating bushing is positioned beyond the end of the alignment sleeve within the lock body and becomes misaligned or offset with the alignment sleeve. To unlock the lock, the alignment sleeve is rotated so that the angled cutout is aligned with the floating bushing of the detachable pin.

  • Patent number: 5675998
    Abstract: A locking device for locking an article to an external structure is provided. The locking device deters theft of the article by being structured so as to cause significant damage to the article, preferably to the point of inoperability, if the article is pulled or jerked away from the external structure. In general, a locking member is threaded, for example, through an opening provided in a critical operating component of the article (such as a circuit board). The opening in the critical operating component is preferably surrounded at its periphery by wiring or other elements which contribute to the operability of the article. The locking member extends to an exterior of the article housing and is secured to an external structure. If the article is pulled or jerked, the locking member generally rips through the circuit board and the wiring thereon, for example, thereby causing significant functional damage to the article and preferably rendering the article inoperative.

  • Patent number: 5199286
    Abstract: A locking device for a drum for chemical- and hazardous-waste containment is described. The locking devices are of drums, usually 30- or 55-gallon sizes, of the closed-end type having a head with two openings or bung holes therethrough. Each drum opening has a flanged or internal portion with interior threads. The locking device has three basic elements, namely, a pair of caps and a slip wrench/locking bar. In one embodiment, one of the caps includes an overpressure relief valve and an flame arrester. Each cap has a threaded base and a larger apertured cylindrical portion mounted thereon. Each cap has a closure gasket mounted at the shoulder formed between the base and the apertured cylinder which gasket permits partial rotation without unsealing the drum. The cylindrical portion of the outer wall has at least two pairs of elongated apertures with 180-degree spacing between the apertures of each pair.

  • Patent number: 5101869
    Abstract: The invention relates to a combined funnel and cap member which can be attached to containers for receiving waste fluid such as fuel or lubricating oils. The cap member is pivotally attached to a funnel body and can be latched to the funnel body opposite the hinge mechanism. The hinge mechanism or the latch mechanism is constructed in such a manner as to permit the cap member to rise relative to the funnel body in the event of overpressures within the container so as to provide an emergency venting path for gases under pressure within the container. Once the overpressure condition has been relieved the cap member will return to its normally closed position under its own weight. The cap member can be unlatched from the funnel body and opened so that fluids may be introduced into the container therebelow.

  • Patent number: 5027627
    Abstract: A locking device for preventing access to a bolt or stud-nut which secures an equipment to a base. The device comprises three parts: a rectangular tube body, a slide member and a lock body. In use, the bolt is put through a hole in the tube body and the equipment, and tightened down. The slide member is then inserted in one end of the tube and slid over the head of the bolt or stud-nut and the lock body is inserted in the tube and locked by a key. This prevents the slide from being removed and prevents access to the bolt head or stud nut. The device is flat and compact, and may be used for a variety of applications where equipments are secured by bolts or stud-nuts, particularly in tight quarters.

  • Patent number: 5010748
    Abstract: A locking device for preventing access to a bolt or stud-nut which secures an equipment to a base. The device comprises three parts: a block, a cover member and a lock body. In use, the bolt is put through a hole in the block and the equipment and is tightened down. The cover member is then fitted over the head of the bolt or stud-nut and the lock body is inserted in the block and locked by a key. This causes the lock to bear down on the cover member, preventing its removal. The device is compact and able to be used for a variety of applications where equipments are secured by bolts or stud-nuts.

  • Patent number: 4959980
    Abstract: A storage drum security apparatus (10) is provided to secure the apertures (24,26) on a storage drum or barrel (12). The apparatus (10) includes a large aperture subassembly (14) and a small aperture subassembly (16) which are interconnected by a securing bar subassembly (18). The first bung member (28) is provided with a post member (40) which extends upward through an isolator member (56) to engage a post receiving hole (98) formed in a flattened portion (92) of the securing bar (90) while the second bung member (66) includes a ball portion (80) on a neck (78) which mates with ball receiving structure (102) in the tubular portion (94) of the securing bar (90). This relationship prevents access to turn either of the bung members (28,66) while the securing bar (90) is in place. The securing bar (90) is also adapted to be used as a wrench to turn both the bung members (28,66 ) when desired.

  • Patent number: 4955501
    Abstract: A trash bin lid-locking device used to secure the lids of a trash bin against unauthorized use. The lid-locking device, which may be used for different types of trash bins, uses two flexible cables connected to two elongated locking members that slide on an elongated track support attached to the front of the trash bin. The locking members may be slid apart allowing the cables to be fit over the front corners and lids of the trash bin. The ends of the cables are then engaged to slotted brackets attached to the sides of the trash bin and the locking members are slid together and secured by a padlock. The cables may be removed from on top of the lids allowing authorized use of the trash bin by unlocking the padlock and sliding the locking members apart until sufficient slack is provided in the cables to allow the cables to be removed. Another embodiment of the lid-locking device uses a single cable that may be placed over the top of the lids.
