Abstract: In an attachment fitting for cylinder locks (3, 3') the heads (4a) of a plurality of screws (4) are seated in a widened hole portion (5a) in the lock. A plugging or latching element (6) is arranged to co-act with a sealing pin (7) in a manner such that when the plug (3a) of the cylinder lock (3) is turned to a given position by means of a key, the sealing pin (7) moves inwardly in a peripheral hole (9) arranged in the plug, against the action of a spring (10). This enables the plugging or latching element (6) to be removed. Because of the presence of the plugging or latching element (6), however, the screw heads (4a) cannot be reached in order to loosen the screws by persons not having the correct key to the cylinder lock. The screws connect the cylinder lock (3) to a further cylinder lock (3') on the other side of the door.

Abstract: A steering lock for an automobile includes a key cylinder, rotatable and axially movable upon rotation of a key inserted in the key cylinder, into locking engagement with a locking bar to lift the latter clear of engagement with a steering shaft. When the key cylinder is turned back and the key is pulled out, the key cylinder is moved back out of locking engagement with the locking bar, which then locks the steering shaft. The returning movement of the key cylinder depresses a spring-loaded control member into a key slot in the key cylinder. When the key cylinder is fully moved back, the spring-loaded control member is pulled out of the key slot. With such an arrangement, the key cylinder can directly engage the locking bar to displace the latter into a retracted position or allow the same to move to a locking position.

Abstract: This invention relates to a method and apparatus for securing a cycle pump. The apparatus consists of a C-shaped holding means adjustably adopted so as to be tightly fitted around the pump body. Lips protrude from the C-shaped holding means and are adaptably fitted to receive a locking means. A cover means is fittingly adapted to permit entry of the lips through the cover means, whereupon the shoulder of the cover is forced against the pump head. This causes the pump body and head to become wedged into the cycle frame pegs. Placing a lock through the lips, which contains holes, prevents the pump from becoming unwedged, thus securing the pump.

Abstract: To prevent removal of laboratory or office equipment and the like, separate cables are attached to four or more items of such equipment and have circumferentially-grooved end members which are received in separate bores in a single lock body and are locked therein by a key-controlled keeper. Preferably, the keeper is a key-removable core inserted in a core chamber which partially intersects the cable-receiving bores, so that the core itself engages in the grooves of the cable end members to lock them against retraction. A mounting screw access passage traverses the core chamber, and is blocked by the core in such chamber to prevent access to a mounting screw inserted through such passage. In a modification, six cable-end receiving bores are circumferentially spaced about the lock body in a common plane. A rotatable keeper plate is mounted in the lock body in a parallel plane and has keeper lugs to engage cable end members inserted in such bores.
