Abstract: An electrical panel locking apparatus includes first and second elongated angle iron bars having panel gripping hooks on one end of each elongated bar. One of the elongated bars has a flanged end portion with an angled slot therethrough for sliding the other elongated bar so that one telescopes inside the other and each angle iron elongated bar has a plurality of openings therein so that openings in one bar can be aligned with the openings in another bar for inserting the shackle of a padlock to lock the bars together. Thus, the hooks on each bar connect to either side of the front panel of an electric box and each has an off-set angle to allow the locking bars to fit over the panel door. The elongated bars can be telescoped to clip around the edges of any size panel and over the panel door and locked in position.

Abstract: A wheel lock is disclosed for securing to the wheel of a vehicle to impede rotation of the wheel to prevent theft of the vehicle. The wheel lock comprises a clamp having opposed arms which are movably coupled together. Each arm carries a projection extending inwardly with respect to the other projection to form an opening therebetween. The projections being carried by the arms can be moved apart to a first position in which the opening is sufficient to be received over the tire and rim of the wheel and the projections can thereafter be moved inwardly to a second position in which the opening between the projections of the opposed arms prevents the clamp from being disengaged from the wheel. The wheel lock further comprises position locking structure for selectively releasably locking the projections of the clamp in the second position to prevent the wheel lock from being disengaged from the wheel.

Releasing of the cable allows the cable and locking bar to drop to a position within the tank whereby the tank closure cap can be removed.

Abstract: A key retaining device for capturing and selectively locking therein a portion of the working section of a key. When the key is locked in the device, its handle section is visible so that the presence of the key can be instantly determined without the unlocking of the apparatus, yet the key cannot be removed from the device until unlocked with a master key. Retention of the key within the housing is accomplished by a clamping mechanism employing a longitudinally sliding member having a wedge-like member which is urged toward the working section of the key upon the sliding member moving in a first longitudinal direction. The sliding member is moved by a bolt coupled to a lock which is rotated by a master key, and a nut which is held in a transverse slot of the slideable member. The master key when rotated in a second direction unthreads the bolt from the nut, moving the sliding member in the opposite longitudinal direction to release the wedge-like member which holds the key.

An elongated channel or slot is integrally formed within the body of the holder so as to allow sliding engagement of the holder on the handle on the top and forcing it to maintain in its in-line and locked position. A latch assembly protrudes through the slot and separated portions of the handle and is latched on the body itself to prevent removal of the lock holder thereby preventing the handle from being positioned into its broken position allowing removal of the auto top.

Abstract: A key retaining device for capturing and selectively locking therein a portion of the working section of a key. When the key is locked in the device, its handle section is visible so that the presence of the key can be instantly determined without unlocking of the apparatus, yet the key cannot be removed from the device until unlocked with a master key. Retention of the key within the housing is accomplished by a resilient clamping mechanism employing a set of wedges which are resiliently urged toward the working section of the key and held there by a rachet spring. Insertion of a master key releases the ratchet spring allowing the wedges to release the key.

Abstract: A locking assembly is provided that can be placed over a push-button keyboard to prevent unauthorized use. The entire keyboard is covered and a tumbler-activating key is inserted externally, rotated and withdrawn. When installed on a telephone, the device allow incoming calls to be received.
