Abstract
Abstract A vehicle theft preventive device that is inserted into the ignition circuit and light circuit of a vehicle that, in response to jump circuiting or short circuiting the battery to the ignition system, the lights of the vehicle are caused to intermittently flash after a given time delay and a solenoid controlled valve is closed in the fuel system stopping fuel flow to the engine.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
An ignition switch jump circuit responsive device for vehicles having an ignition switch circuit for electrically connecting the vehicles ignition system to an electrical power source, and a light switch circuit for electrically connecting the vehicle''s lights to the electrical power source, comprising, flasher circuit means for overriding said light switch circuit and flashing the vehicle''s lights when said flasher circuit means is energized, circuit means for energizing said flasher circuit means in response to jump circuiting the power source to the ignition system when the ignition switch circuit is open, said circuit means includes timer means for delaying the energizing of said flasher circuit means for a given period of time, solenoid valve means for stopping fuel flow to the engine in the vehicle when said solenoid valve means is de-energized, solenoid circuit means operable by the ignition switch circuit for energizing said solenoid valve means, and said solenoid circuit means being non-responsive to jump circuiting the power source to the ignition system.
Claim 2
Dependent Claim
164 words
An ignition switch jump circuit responsive device for vehicles having an ignition switch circuit for electrically connecting the vehicles ignition system to an electrical power source, and a light switch circuit for electrically connecting the vehicle''s lights to the electrical power source, comprising, flasher circuit means for overriding said light switch circuit and flashing the vehicle''s lights when said flasher circuit means is energized, circuit means for energizing said flasher circuit means in response to jump circuiting the power source to the ignition system when the ignition switch circuit is open, said circuit means includes timer means for delaying the energizing of said flasher circuit means for a given period of time, solenoid valve means for stopping fuel flow to the engine in the vehicle when said solenoid valve means is de-energized, solenoid circuit means operable by the ignition switch circuit for energizing said solenoid valve means, and said solenoid circuit means being non-responsive to jump circuiting the power source to the ignition system.
Claim 3
Dependent Claim
38 words
An ignition switch jump circuit device as claimed in claim 1 wherein, said flasher circuit means energizes the left rear light independently of the right rear light and the left front light independently of the right front light.
Claim 4
Dependent Claim
37 words
In an ignition switch jump circuit responsive device as claimed in claim 2 including, first switch means responsive to the closing of the ignition switch circuit for opening said circuit means and closing said solenoid circuit means.
Claim 5
Dependent Claim
52 words
In an ignition switch jump circuit responsive device as claimed in claim 3 including, said flasher circuit means includes relay means that is energized by the timing out of said timer means for closing switch contacts that opens said light switch circuit and closes the flasher circuit means to the power source.
Claim 6
Dependent Claim
25 words
In an ignition switch jump circuit responsive device as claimed in claim 4 including, manually operable switch circuit means for energizing said flasher circuit means.
