    Abstract: A display type of sleeve envelopes the major portion of the elongated shackle of a bicycle padlock or the like and retains in the sleeve against removal by a tamperer a ''''bubble'''' like key enclosure. The padlock body applied externally to the protruding inner ends of the shackle legs closes the bottom of the sleeve and prevents movement of the padlock assemblage in one direction, while the closed end of the shackle bridges walls or shoulders at the top of the sleeve to prevent withdrawal movement of the shackle from the sleeve in another direction. The sleeve containing the padlock assemblage for shipping and customer inspection at a dealer''s, renders the product visible.

    Abstract: For goods or materials which are shipped or stored under seal there is provided a key-actuated lock formed on one wall with a channel plate having an opening therein registering with the keyway of the lock. The channel plate is adapted to hold over the lock keyway and in guarding relation thereto, a portion of a sealing element. As long as the sealing element remains intact and in position it is impossible for a tamperer to gain unauthorized access to the lock keyway. However, if the seal should be removed or broken, thus giving visual evidence of tampering, the lock must, nevertheless, be illegally opened to give a tamperer access to the protected goods, thereby providing double security.

    Abstract: THEIS PERMUTATION PADLOCK CONTAINS MECHANISM WHICH, FOLLOWING THE DIALING OF THE LAST NUMBER OF THE COMBINATION AND THE WITHDRAWAL OF THE SHACKLE TO ITS OUTER RELEASED POSTION, WILL AUTOMATICALLY TURN THE DIAL SUBSTANTIALLY AWAY FROM THE LAST DIALED NUMBER THEREON. THE IMPROVED MECHANISM ALSO INCLUDES A CONFINED BAND SPRING ENGAGING THE SHACKLE LOCKING LEVER IN A MANNER SO AS TO RELIEVE THE PRESSURE EXERTED ON THE TAIL OF THE LEVER RESULTING FROM THE WEIGHT OF THE PADLOCK BODY WHEN THE SAME IS SUSPENDED FROM A SHACKLE ENGAGED HASP STAPLE OR THE LIKE, THUS INSURING FREE AND PROPER OPERATION OF THE PADLOCK RELEASE MECHANISM INCLUDING THE DIAL NUMBER UPSET ABOVE REFERRED TO. MOREOVER, THE LOCKING LEVER TAIL UNDER THESE CONDITIONS IS MAINTAINED OUT OF CONTACT WITH THE TUMBLERS WHEREBY A TAMPERED CANNOT "FEEL OUT" THE POSITIONS OF THE TUMBLER GATES, AND THUS SURREPTITIOUSLY, FIND THE COMBINATION.
