Abstract
Abstract Apparatus for protecting a vehicle such as an automobile from theft and/or other improper use including a first double pole double throw switch, a relay having first and second normally open controlled switches and a second normally closed double pole, double throw switch. When the first switch is manually shifted to the protective position, the first switch electrically connects the primary winding of the ignition coil or the like to ground so that the vehicle cannot be started and also electrically connects the vehicle battery to the relay via the vehicle devices which operate off the battery so that if any of these devices are used while the first switch is in the protective position the relay is activated. The activation of the relay causes a latching current path to be completed in parallel with the vehicle devices so that the relay remains activated even if all vehicle devices are thereafter shut off, and further causes a noisemaker such as the vehicle horn to be connected to the battery to sound an audio alarm. Once activated the relay remains activated until the first or second switch is manually opened.

Claim 1
Independent Claim
329 words
Apparatus for protecting a vehicle having a battery, an ignition switch, ignition coil, for starting said vehicle with one side of a winding connected to ground and the other side connected to said battery via said ignition switch and a plurality of electrical devices operable off said battery comprising: a relay with a coil having one side connected to one side of said devices and first and second controlled, normally open switches, a first double pole double throw switch having a first protective position connecting said other side of said winding to ground so that said vehicle cannot be started and a short circuit of said ignition switch connects said battery in a short circuit and connecting the other side of said relay coil to said battery so that whenever said first double pole switch is in said first position, and any of said devices are operated, current flows through said relay coil to cause said first and second controlled switches to close and a second position disconnecting said other side of said winding from ground and connecting said one side of said devices to one polarity of said battery, and a second double pole double throw switch having a first position connecting said one side of said devices and said one side of said relay coil to the other polarity of said battery via one of said controlled switches so that said devices cannot be operated when said one controlled switch is closed and said first double pole switch is in said first position and connecting said battery to a noisemaker via said first double pole switch and the other of said controlled switches so that when said first double pole switch is in said first position and said other controlled switch is closed said noisemaker sounds an alarm and a second position disconnecting said one side of said devices and said one side of said relay coil from said battery and disconnecting said noisemaker from said battery.

Apparatus for protecting a vehicle having a battery, an ignition switch, ignition coil, for starting said vehicle with one side of a winding connected to ground and the other side connected to said battery via said ignition switch and a plurality of electrical devices operable off said battery comprising: a relay with a coil having one side connected to one side of said devices and first and second controlled, normally open switches, a first double pole double throw switch having a first protective position connecting said other side of said winding to ground so that said vehicle cannot be started and a short circuit of said ignition switch connects said battery in a short circuit and connecting the other side of said relay coil to said battery so that whenever said first double pole switch is in said first position, and any of said devices are operated, current flows through said relay coil to cause said first and second controlled switches to close and a second position disconnecting said other side of said winding from ground and connecting said one side of said devices to one polarity of said battery, and a second double pole double throw switch having a first position connecting said one side of said devices and said one side of said relay coil to the other polarity of said battery via one of said controlled switches so that said devices cannot be operated when said one controlled switch is closed and said first double pole switch is in said first position and connecting said battery to a noisemaker via said first double pole switch and the other of said controlled switches so that when said first double pole switch is in said first position and said other controlled switch is closed said noisemaker sounds an alarm and a second position disconnecting said one side of said devices and said one side of said relay coil from said battery and disconnecting said noisemaker from said battery.
