Abstract: A cable locking device consisting of two axially slotted cylindrically shaped closed-end structures, each having attached a rigid tube of smaller diameter than the cylinder. The length of each tube is greater than half the wheelbase of a skateboard, and one tube will fit within the other. The axial slots allow each cylinder to be guided over the trucks of a skateboard, entirely encompassing the truck and associated mounting hardware. Upon installation of the device, the smaller rigid tube has been incorporated within the larger tube. The free end of an attached locking cable is inserted into two aligned apertures, one on each tube, and a locking device contained within the larger tube secures the cable in place.

Abstract: A key-in-lever type door lock which can be installed on either a left hand or right hand door by a left-right reverse operation of a reverse plate. The lock comprises a lock assembly which regulates a uni-directional, 45-degree rotation of a handle thereof and a latch assembly which converts the 45-degree rotational movement to a retraction of a latch bolt. The lock is jimmy-proof, i.e., secure against improper manipulation, by the provision of a latch stop pivoted to the latch bolt and being movable together therewith. The latch stop, which has a catch end normally blocked by a retaining plate, is operationally pivotable about the latch bolt to release the blockage, thereby permitting a relative sliding movement between the latch stop and the retaining plate.

Abstract: A padlock with removable cylinder mechanism offers the user a choice of two distinct manners of operation or "functions"--a Key Retaining function and a Non-Key Retaining function. This dual function capability in a single unit is achieved by a rotator bolt bored to allow placement of a pattern of pins. A series of pins, which when installed in the rotator bolt in a specified pattern, causes the function selection to be accomplished. A re-keyable padlock which accepts widely available, standard dimensioned, generic key operated lock cylinders allowing the keying of this padlock to be adapted to the wide range of keying systems used in locks found in residential, commercial and other uses as required for security and convenience. The use of standard dimensioned cylinders in the padlock is accomplished by a cylinder retainer, tailpiece stop and rotator bolt which adapts the generic cylinder to padlock use.
