Abstract: A lockable wheel coupling comprises an axle plate having a splined shaft with a central bore, a wheel having a fluted axial bore, and a generally cylindrical locking member. The wheel can be mounted on the axle plate by engaging the shaft thereon with the axial bore of the wheel. Spring biased and radially displaceable retaining lugs within the central bore are engaged with retaining recesses on the inner periphery of the axial bore via aligned apertures in the shaft upon insertion of the locking member into the central bore, to releasably secure the wheel to the axle plate. The locking member carries a cam surface for displacing the retaining lugs outwards into corresponding retaining recesses and a set of locking bolts that snap engage into an annular locking recess in the inner periphery of the central bore to retain the locking member therein. A key operated lock cylinder within the locking member retracts the bolts when rotated so that the member can be removed from the central bore.

Abstract: The automobile anti-theft device consists of a hardened steel collar which encircles the steering column of the automobile and includes two rotatably attached sections which are attached to each other by sliding one end of a first section underneath an end of the second section. The first section has a projection on the end which fits into a radially extending recess on the underside of the second section and thus acts as a pivot point about which the first section rotates relative to the second section. The first section consists of an arcuate body, which is shaped to cover a portion of the side of the steering column, and a projection which extends radially out from the arcuate body. When this section is in place on the steering column, the projection is thus approximately perpendicular to the steering column. The second section consists of an arcuate body which is shaped to cover a portion of the steering column which is contiguous with and on the same side as the portion covered by the first section.

Abstract: An anti-theft system and method for automobiles cuts off the fuel supply from the gas tank by not opening a cutoff valve if a car has been improperly started. Auxiliary units associated with the ignition and the gas tank require that a certain timing sequence be gone through in starting; if the key is accidently left in the ignition for an extended period of time, the fuel will be shut off, or if the car is hot wired, the fuel will be shut off. In either case, an operator's personal code must be re-entered.

Abstract: A method and device for the electrical control of a central locking system and of a mechanical securing device (that provides additional lock protection) for motor vehicles by a lock cylinder that interacts with at least two control switches. This method and device ensures a better utilization of the electrical control switches, in that, an unlocking control switch assigned to the unlocking of the central locking system and the deactivation of the mechanical securing device is switched in addition to a locking control switch assigned to the locking of the central locking system. If the lock cylinder is pivoted in the locking direction beyond its regular locking position, the resultant joint switching state of the two switching control devices is evaluated to activate the mechanical securing device.

Abstract: A substantially "U" shaped break-away-bar assembly is constructed to a size and configuration to fit about a portion of an air-inflated vehicle tire. A key actuated lock latching assembly is carried by the break-away-bar assembly and includes an internally threaded connection member utilized to selectively connect the latching assembly to the external threads normally provided on a valve-stem of a tire rim for an air inflated vehicle tire.
