A bi-directional locking socket for use with a seal device which includes a shackle having a plurality of locking elements on a surface thereof. The socket comprises a locking insert forming a locking arrangement including a body defining a chamber therein. The locking insert further includes opposing top and bottom ends where the top end defines a top opening communicating with the chamber, and the bottom end defines a bottom opening communicating with the chamber. A plurality of mirror image spaced fingers define a passageway extending through the chamber. The plurality of fingers allow passage of the locking elements as a free end of the shackle is pulled through the passageway via either the top or the bottom openings in opposite insertion directions, and lock with a locking element of the shackle when the shackle movement is in an opposite direction to the insertion direction. In the alternative, the socket has a chamber with the locking arrangement formed one piece therewith.

Pull seal with bi-directional locking arrangement

A molded thermoplastic body is formed with a rectangular cavity. A molded thermoplastic insert is welded to the body in the cavity and has a top cross member, a stem member and a bottom member. The stem member has a plurality of molded fingers cantilevered on opposing sides inclined relative to the stem member longitudinal axis in one embodiment. The stem member forms the cavity into two channels. A wire shackle which may be round or square in section, a wire or molded plastic, is U-shaped with two legs. One leg is formed with notches to receive the tips of the fingers in one channel and the other leg is formed with a reversibly bent barb which engages the fingers in the other channel on the opposite side of the cavity. The bottom member limits the insertion depth of the legs. The notches and barb engage the fingers and lock the shackle to the body. When the shackle is severed, and the notched leg rotated to disengage the notches in the leg from the fingers to remove the leg from the body, the other leg with the barb can not be rotated and readily removed to thereby provide evidence of tampering. Other embodiments are disclosed including providing the notched leg with squared sides and an entrance opening into the corresponding channel that is square to preclude rotation of the notched leg and shackles of different configurations.

Padlock seal

A thermoplastic housing has a chamber open at one end and a thermoplastic rotor is locked axially in the chamber by snap fit ridges and grooves. Two pairs of bores on opposite sides; of the chamber are aligned, with one pair connected by a transverse slot. The rotor has two bores aligned with the housing bores and includes flexible pawl teeth which engage ratchet teeth in the chamber. The teeth rotationally lock the rotor relative to the housing in one direction while a seal filament inserted in the bores is wrapped about the rotor as the rotor is rotated in the other direction. The slot permits the filament to be fixed to the rotor when the rotor is rotated 180.degree. causing the filament to traverse the slot and permit the remaining adjacent bores in the same plane as the fixed filament to be aligned and free to receive the filament free end. The rotor is rotated relative to the housing manually by finger gripped flanges attached to the rotor and to the housing with the filament inserted to wrap and lock the filament to the rotor. The rotor and housing define a channel for receiving multiple turns of filament to enhance the locking action.

Rotatable seal

A one piece molded thermoplastic, preferably polypropylene, high security seal for coin bags has a locking socket body from which a flag extends on one side and a rectangular flat elongated shackle extends on the opposite side via an intermediate flat member which has a tear band there across for selectively separating the member into two pieces to facilitate removal of the locked seal. The shackle has several locking circular segment teeth in two parallel linear arrays on opposite edges of the shackle adjacent to a tamper resistant flange at the member end. A locking sheet metal stamped insert has two sets of tangs defining two spaced tooth receiving openings in a socket locking cavity aligned with shackle receiving openings in the body. The body receives the insert transverse to the shackle insertion direction through a cavity side wall later sealed with a flap formed in the seal body. The locked shackle precludes removal of the insert should the side wall seal be tampered with. The locked shackle forms a closed loop passed through an aperture in the bag folded neck. A hook on the intermediate member forms a tear band tab and engages the bag neck in the seal locked condition.

Thermoplastic security seal

A padlock type security seal and method of making same include a U-shaped shackle, a pair of reversely bent end portions, and a transparent body having a pair of chambers for receiving the bent end portions. The chambers each have a locking groove therein for receiving the bent end portions. The seal elements are formed from two molded thermoplastic pieces, an insert and a body. The relative dimensions of the chambers, the shackle, and the locking grooves are chosen to prevent picking. The insert has a channel in which a liquid filled vial is inserted. The vial contains a colored liquid. When the shackle is attempted to be removed from the body portion, the shackle end portions penetrate the insert and the vial causing the liquid to seep into the various chambers, the seepage being visible through the body.

A sealing ring for an electric meter socket has first and second spaced ends. A tongue with a plurality of linearly spaced apertures extends linearly outward from the first end of the sealing ring. A housing is mounted on the second end of the sealing ring and includes a passage for receiving the tongue therethrough. A threaded fastener is mounted in the housing and engages successive apertures in the tongue to advance and retract the tongue through the housing to connect and disconnect the sealing ring about the electric meter socket. At least one and preferably two seal tabs extend outward from the second end of the band and engage the apertures in the tongue. A seal member is emplaceable through the seal tabs to indicate a sealed mounting on the sealing ring on the electric meter socket.

Electric meter socket sealing ring

A padlock-type security seal including a U-shaped shackle having a pair of reversely bend end portions. A body portion and a brightly colored insert are assembled to form a pair of chambers for receiving and locking the bent end portions. Movable tangs and matching cavities are formed as an integral part of the insert adjacent the chambers. The body portion has a plurality of transparent windows adjacent the cavities. Attempts to open the seal by deforming the shackle to remove the bent end portions from the chambers will result in moving the tangs into locking containment with the cavities thereby visually indicating tampering via the transparent windows.
