Anti-theft system for an automotive vehicle

Claim 1

An anti-theft system for an automotive vehicle having operational components including a storage battery, electrical ignition coil, headlights, horn, brake lights, reverse lights, and chassis-grounded electrical distribution system, said anti-theft system, comprising: (a) a first circuit employing relay means having a coil activated by a positive flow of twelve volt direct current from the automotive vehicle's brake and/or reverse lights circuits, said current having passed through a first SPST activate switch, said coil being negatively grounded through a second SPST switch which is either hidden or key-activated, (b) a second circuit which grounds the spark from the automobile ignition coil to the chassis of the automobile upon activation of said relay means, thereby disabling the ignition of said automobile. (c) a third circuit controlled by said relay means, which provides current from the automobile's battery to the automobile's horn, (d) a fourth circuit controlled by said relay means, which provides current from the automobile's battery to the automobile's headlights, and (e) a fifth circuit controlled by said relay means and providing current from the automobile's battery to activate said relay means in a manner bypassing the brake and reverse light circuits, thereby rendering said first SPST switch useless and causing said second SPST switch to be the only means for turning off the horn and headlights and re-starting the automobile.
