Filed:

Appl. No.:

8/221589

International Classification:

F16G 1100

US Classification:

24136R

Abstract:

A stamped hardened sheet steel tapered ferrule with cantilevered radially resilient fingers is wedged by a spring against a tapered bore of a hardened steel housing. The fingers bend radially inwardly to grip a stranded steel cable in the ferrule bore in response to the spring action. When the cable is slid in the ferrule in one direction, the ferrule gripping the cable is further wedged against the tapered bore and further grips the cable. The cable is released when it is slid in the opposite direction pulling the engaged ferrule away from the tapered bore of the housing. The cable has a flag at one end which with the seal lock a hasp therebetween limiting the relative motion of the cable in the opposite ferrule release direction. In a second embodiment, the ferrule is in interference fit with a rod or cable and the spring is not used forcing the ferrule to always grip the rod or cable. The ferrule in both embodiments grips the softer cable with higher rotational force than the ferrule friction force with the housing bore so that rotation or twisting of the cable relative to the housing rotates the ferrule therewith.

Assignee:

Tranguard Industries, Inc. - Angola IN

International Classification:

E05C 304

US Classification:

292202

Abstract:

Two mating L-shaped steel sheet casing members in one embodiment for sliding doors are secured to a corresponding door and have overlying front walls in the closed state. Each member has a plurality of corresponding locking keeper elements. In the closed state the keeper elements are in interdigitated juxtaposed and preferably welded to the casing members via through optional bores in the casing members, or extend through the side walls of the casing formed by side wall sections. The keeper elements in one subassembly are slotted to allow for misalignment with the other keeper elements for receiving a locking bolt seal shaft. The keeper elements optionally have tongue projections for engaging a gap between the closed doors. An angle iron member shields the rear of the chamber below the lowermost locking element to protect the seal locking body. Other embodiments are disclosed and include cast assemblies with no weldments and a single casing and hasp for use with swinging doors or a rail car plug door.

International Classification:

G08B 1314

US Classification:

3405681

Abstract:

A molded transparent thermoplastic housing has a programmable transmitting circuit for transmitting seal identifying serial number, seal location, container identification and other data to a local receiver. A door in the housing permits access to the circuit for programming the seal indicia and related data for transmission. A contact arrangement forms a switch upon insertion of a locking bolt into a locking mechanism in the housing and applies battery power through the bolt to activate the data generating circuit. A conductor along the bolt shank is connected to the circuit provides a tamper evident signal to the circuit when the bolt is severed. The circuit senses the removal of the bolt or severed bolt condition for generating a "tamper" signal which is transmitted to a local receiver/reader. The conductor at the bolt may be a wire in a plastic tube surrounding the shank, a conductive layer over an insulation layer on the shank and over the conductive bolt head in ohmic contact with the head or a wire in a hollow metal tube. Severing the bolt severs the wire or the ohmic contact between the head and coating or between the head and the wire in the tube to indicate tampering.

International Classification:

E05B 6738

US Classification:

70 56

Abstract:

A plurality of walls form a housing cavity in which a latch hasp is received. An opening in the housing receives therethrough the latch hasp, the latch enclosing the cavity. The bolt seal has a shank with a head at one end or with a U-shaped bight in a second embodiment. The head engages a housing wall and a locking body engages and locks to the shank at a shank end distal the head. The shank between the head and lock body is fully enclosed by the housing and latch to preclude access to the shank by tampering tools. In a second embodiment, the shank bight engages the received hasp of a latch. The shank distal the bight is locked to the housing by a locking body. The latch depends into and encloses the housing cavity open at the top. The shank between the bight and the locking body is fully enclosed in the cavity. Different housings are disclosed wherein the head may be enclosed or exposed for access by a shank breaking tool.

David Stevenson - Angola IN

Assignee:

Transguard Industries, Inc. - Angola IN

International Classification:

E05B 3902

US Classification:

292327

Abstract:

A steel bolt has weakening grooves at one end to which a head is swaged, the head having two frusto-conical portions at opposite ends. One end has a frusto-conical step for receiving a pair of jaws of a bolt breaking tool. A resilient spacer is attached to the bolt next to the head for limiting the depth of entry of the bolt head into a hasp hole, to provide access clearance for the tool and to permit the bolt to tilt to assist in breaking the bolt. The spacer is received in one hasp hole smaller in diameter than a second hasp hole to limit the depth of insertion of the spacer and the bolt head tapered end portion into the hasp. A seal with a conventional locking mechanism has a frusto-conical end region which partially engages the other hasp hole. The bolt and seal cooperate to lock the seal axially at different positions so the seal is engaged with one hasp hole and the bolt head engaged with the other hasp hole. A tool is disclosed which mates with the bolt head for breaking the bolt at the head when used with J-shaped hasps with limited tool receiving space.

International Classification:

E05B 3902

US Classification:

292327

Abstract:

A lock body through bore receives a steel bolt with an array of annular grooves. A locking mechanism secured in the bore has an annular array of locking jaws normally biased engaged with an inserted bolt groove. A jaw spreader has a conical surface for spreading the jaws radially outwardly to disengage the bolt. A locking member normally is radially outwardly of the jaws to preclude such spreading. A spring with a high spring constant, e. g. , 300 pound load, axially biases the locking member in the jaw locking position. The spreader and locking member define a locking jaw conical path for radially outwardly releasing the jaws during bolt insertion and for locking the jaws in the opposite bolt withdrawal direction. A manually operated tool with a rotatable cylinder which engages the spreader and including a pair of lock gripping tines provides a high force to the spreader to axial displace it against the locking member spring to release the bolt locking jaws while simultaneously radially outwardly releasing the jaws from the bolt.
