Abstract: A key-operated cylinder lock for operating a bolt or a latch, that can be programmed for use with one of a plurality of user keys without disassembling the lock or replacing the tumblers, with reduction or elimination of incidental or accidental re-keying of the lock. The lock has a rotating plug having one or more retainer cavities formed into the periphery, and lock configuration change balls, movable within the lock between a first position within a driver chamber and a second position within a corresponding retainer cavity when the plug is in a programming position. The positioning of the change balls within either the pin chambers or the retainer cavities determines the key configuration that can operate the lock. The lock employs a means for isolating selectively the retainer cavities from the corresponding driver chambers when the plug is in the programming position, to prevent incidental or accidental movement of the change members from the driver chamber into the retainer cavities.

Abstract: An anti-theft device comprises a housing for enclosing and locking in place the accelerator pedal of vehicles such as a golf cart. The housing is formed from rigid steel or other suitable materials and includes an open top and a bottom having a T-shaped opening therein to allow the accelerator pedal to be inserted therethrough. An L-shaped retaining rod is placed through an opening in one side of the housing, slid behind the accelerator pedal and positioned through the opening in the opposing side of the housing. A padlock or similar device is placed through an aperture in the retaining rod to secure the housing to the golf cart and prevent depression of the accelerator pedal. The anti-theft device thus prevents the accelerator pedal from being depressed and the vehicle being moved or stolen.

Abstract: By providing a single housing and shackle assembly constructed for enabling the shackle to be opened and/or closed using either a rotatable dial combination construction or a key activating tumbler construction, with the movement of the shackle being controlled by a trigger member, an effective, easily produced, padlock is achieved which incorporates two separate and independent locking systems formed in a single padlock. In addition, the trigger member and shackle each incorporate uniquely constructed, cooperating surfaces, each of which comprise a grooved zone or concave curved zone which is positioned directly adjacent a cooperating convexly curved zone. By employing these two curved surfaces on both the shackle and trigger member, the controlled pivotal movement of the shackle is realized.
