Abstract
Abstract A fuel line lock for locking the fuel line of an automobile or other motor vehicle is disclosed. A push button locking member is mounted within the driver''s compartment to close a reciprocating valve mounted in the fuel line between the fuel tank and the engine. The valve includes a resilient biasing means which normally biases the valve to its open position. The locking member includes a key operated tumbler and is reciprocally linked to the fuel line valve by means of an armored and flexible cable. As the lock member is depressed, the fuel line valve is closed and the lock is engaged. The lock is disengaged by rotating a key operated tumbler which unlocks the reciprocating member and allows the valve to be opened by the resilient biasing means.

A fuel line lock for a motor vehicle comprising a. a fuel line valve adapted to be to the fuel line of the motor vehicle, said valve comprising, i. a valve body, said valve body comprising a standard fuel line tee-fitting with a fuel inlet, a fuel outlet, and a branch outlet with cylindrical fuel passageways defined therebetween, said branch outlet providing a reciprocating passageway disposed perpendicularly and communicating with the passageway defined between said inlet and outlet; ii. a valve member for reciprocating within said branch passageway, said valve member being cylindrical and sized to the interior diameter of the fuel passageway defined within said tee-fitting, said valve member having a first closed and second open position, said valve member completely closing said fuel passageway when reciprocated to its first position, said valve member also defining an angular flange which reciprocates within the branch outlet of said tee-fitting; iii. a helically coiled spring mounted within said branch outlet and surrounding said valve body to engage said angular flange and thereby urge said valve member to its second open position; b. actuating Means for said fuel line valve, said means comprising a flexible reciprocating member with a flexible armored cable housing, said housing being fixably attached to said valve body through a terminal flange which is secured to said standard tee-fitting with a fuel line nut, said flexible reciprocating member being fixably attached to said valve member; c. lock means for mounting within said motor vehicle, lock means comprising i. a housing member for securing said lock to said motor vehicle, said housing member defining a reciprocating passageway and at least one indent; ii. a key operated reciprocating member mounted for reciprocation within said reciprocating passageway between a first depressed position and a second released position, said lock means being fixably attached to said flexible reciprocating member to reciprocate said valve member to its first closed position as said reciprocating member is depressed; iii. engagement means mounted within said reciprocating means for engaging said indent when said reciprocating means is reciprocated to its first position, said means thereby securing said valve member in its first closed position.
