Abstract: Automobile theft is running rampant throughout the country, and many automobile stealing organizations are well organized, and have the necessary techniques to enable them to select and steal virtually any automobile. In a matter of a few hours they can change numbers, and other identifying data and give the automobile a new identity and appearance so that the automobile can be quickly sold at somewhat reduced prices. The overall profits are indeed very substantial. We have devised a theft proof locking system, including a key operated unit, which can be positioned at any desired location in the vehicle, and is operable to fully apply the brakes to all four wheels of the vehicle. This renders the vehicle immobile, even though the engine can be started and run. The only way that this locking system can be rendered inoperable is by the act of unlocking it with the key. It is therefore impossible to move the vehicle without lifting it bodily to load it onto a trailer or transport.

Abstract: A fastening device for releasably or non-releasably fastening free ends of two parts of a neck strap or crown jam of a halter to each other. Each of the two parts has one end fixedly connected to another part of the halter and one end free. A free end of one of the neck strap parts is connected to a buckle. The free end of the other neck strap part is formed of two overlapping straps. Both straps near their free ends contain a plurality of aligned holes, a selected pair of which are engageable by the buckle to non-releasably fasten the ends of the two parts of the neck strap or crown jam to each other. A two-section releasable fastener is attached to one of the surfaces of the two straps near its free end. The two sections are engaged with each other when the strap is passed through the buckle and folded back on itself. The engaged sections resist separation upon application of longitudinal tensile forces of ordinary value, but when the magnitude of any such force exceeds a predetermined value, they separate.
