Abstract

Abstract An electrical lock for vehicular ignition systems having adapters that are irremovably interposed between a predetermined number of spark plug cable receptacles and their distributor contacts. The adapters being of two types, a normally open contact type and a normally closed contact type, the normally open contact-type adapter having a spring-loaded solenoid which is activated by an electric key closing an electric circuit to direct current to the solenoid to overcome the spring and close the adapter permitting current to flow from the ignition system battery through the distributor contacts through the spark plug cable to the individual spark plug of the vehicular engine for its operation. The normally closed contact-type adapter has a spring-loaded solenoid which permits electric current to flow from the battery, through the distributor contacts, through the spark plug cable, to the individual spark plug of the vehicular engine. The normally closed contact-type adapter is not effected by the electric key. In the event the electric circuit of the normally closed adapter is tampered with, to cause current to flow to its solenoid, it will activate it to overcome the spring and open the adapter thus preventing current from flowing to the spark plug.

Claim 2
Dependent Claim 172 words
An electrical lock for a vehicular ignition system including a battery, distributor contacts for receiving electrical current from said battery, and spark plug cables electrically connected to said distributor contacts for receiving the current from said distributor contacts and directing the current to spark plugs in starting the engine, the improvement comprising, adapter means interposed between one or more distributor contacts and spark plug cables, said adapter means including solenoid means operable for controlling the high current flow from the distributor contacts through the solenoid means to the spark plug cables, and a low-voltage electrical circuit means, said low-voltage circuit means operating said solenoid means to allow high current flow through said solenoid means, said low-voltage means including a plurality of low-voltage conductors connected to the battery in a predetermined combination that must be known to properly effect current flow through the adapter to provide a continuity in the ignition system whereby the high voltage of said ignition system is controlled by the low voltage of the system to start the engine.
Claim 3
Dependent Claim 264 words
An electrical lock for a vehicular ignition system including a battery, distributor contacts for receiving electrical current from said battery, and spark plug cables electrically connected to said distributor contacts for receiving the current from said distributor contacts and directing the current to spark plugs in starting the engine, the improvement comprising, adapter means interposed between one or more distributor contacts and spark plug cables, said adapter means controlling the current flowing from the distributor contacts to the spark plug cables, and an adapter electrical circuit means including a plurality of conductors connected to the battery in a predetermined combination that must be known to properly effect currEnt flow through the adapter to provide a continuity in the ignition system to start the engine, wherein the spark plug cable, used with each adapter means, includes a one-way lock clip, and wherein said adapter means, interposed between a distributor contact and a spark plug cable, includes a female spark plug cable electrical contact receptacle and an opposed male electrical contact pin, said male pin having a one-way lock clip, and further wherein said distributor contact includes a female electrical contact receptacle, whereby when said adapter means is interposed between said distributor contact and said spark plug cable, the spark plug cable is irremovably secured within the adapter female spark plug cable receptacle and the adapter male contact pin is irremovably secured within the distributor female contact receptacle to thereby prevent the removal of said adapter means without destroying said adapter means and said electrical connections and in turn destroying the continuity in the ignition system.
Claim 4
Dependent Claim 264 words
An electrical lock for a vehicular ignition system including a battery, distributor contacts for receiving electrical current from said battery, and spark plug cables electrically connected to said distributor contacts for receiving the current from said distributor contacts and directing the current to spark plugs in starting the engine, the improvement comprising, adapter means interposed between one or more distributor contacts and spark plug cables, said adapter means controlling the current flowing from the distributor contacts to the spark plug cables, and an adapter electrical circuit means including a plurality of conductors connected to the battery in a predetermined combination that must be known to properly effect currEnt flow through the adapter to provide a continuity in the ignition system to start the engine, wherein the spark plug cable, used with each adapter means, includes a one-way lock clip, and wherein said adapter means, interposed between a distributor contact and a spark plug cable, includes a female spark plug cable electrical contact receptacle and an opposed male electrical contact pin, said male pin having a one-way lock clip, and further wherein said distributor contact includes a female electrical contact receptacle, whereby when said adapter means is interposed between said distributor contact and said spark plug cable, the spark plug cable is irremovably secured within the adapter female spark plug cable receptacle and the adapter male contact pin is irremovably secured within the distributor female contact receptacle to thereby prevent the removal of said adapter means without destroying said adapter means and said electrical connections and in turn destroying the continuity in the ignition system.
