  • Patent number: 4059300
    Abstract: A seal of the type having a housing with internal resilient fingers for receiving a shouldered stud in locking engagement, in which a separate cylinder is provided in the housing for closely surrounding the entire periphery of an end portion of the stud protruding beyond the resilient fingers to maintain the stud centered in the opening and prevent any lateral movement thereof, and thereby prevent attempts to open the stud by the insertion of tools to dislodge the resilient fingers from engagement with the stud. The cylinder surrounding the stud is inserted into the end of the housing remote from the stud-receiving end, and said remote end is then deformed with heat to retain the cylinder in the housing.

  • Patent number: 3980337
    Abstract: A locking seal for use on doors of freight cars, trailer trucks and other large doors to prevent casual pilferage by non-professional thieves. In a first embodiment a length of steel cable is provided with means on each end for locking engagement with each other. In a second embodiment of the invention, a length of steel cable is provided with a stop on one end and the other end is provided with an assembly comprising a locking cap and means secured to the cable for receiving the locking cap in non-removable engagement. The locking means of either embodiment is adapted for rapid assembly without the use of special tools, yet the design of the two locking portions thereof gives the assembly a strength of engagement which is greater than the strength of the steel cable connecting the portions. The male portion of the locking means, when assembled, is completely enclosed within the female portion to protect the attachment of the cable to the male portion from physical damage.
