Abstract

ABSTRACT

Stop-a-Thief is a "passive" theft prevention system for vehicles.
It automatically protects the vehicle from being driven away and does not rely on the driver for activation. The owner of the vehicle must by-pass this protection each time he starts his vehicle by pressing down,or closing,a momentary switch. However,when the ignition switch is turned off,Stop-a-Thief is automatically reactivated. This theft prevention is achieved on all 12-volts ignition systems by intercepting the wire that connects the two terminals of the primary circuit between the coil and the distributor and connecting these extremities to Stop-a-Thief.

Claims (2)

THE EMBODIMENT OF THE INVENTION IN WHICH AN EXCLUSIVE PROPERTY OR
PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A passive theft prevention device for vehicles having an ignition switch,ignition coil,and a distributor comprising of a normally open double pole-single throw electromechanical relay with a relay coil in which one pole is utilized to sustain the relay coil loop across a normally open momentary switch connected in series with the relay coil,while the other pole is connected across a "cut" on the primary circuit of a 12-volts ignition system, and an overload relay with an automatic reset connected in parallel to the other pole of the relay that connects across the "cut" on the primary circuit of the ignition system so that the overload relay must be by-passed each time the vehicle is to resume normal operation by pressing down or closing the momentary switch.
2. A passive theft prevention device for vehicles as defined in claim 1 with the other pole of the relay connecting across the "cut" on either one of the leads of the electrical fuel pump.
