Abstract

An anti-theft device for an automotive vehicle, the device comprising a gasoline shut off valve; the valve not preventing the engine from being started, but being able to cause the engine to come to a stop when the gasoline supply in the carburator is used up.

Claims

1. A vehicular fuel lock for controlling the flow of fuel in the supply line to the carburetor, of an internal combustion engine, comprising a valve mounted in the supply line in combination with a valve actuating device mounted in the vehicle adjacent said valve and having a valve actuator movable from a position spaced from said valve to a position engaging said valve, including coacting means on said valve and actuator whereby said actuator can move the valve from a closed to open position and from an open to closed position when said actuator is in engagement with said valve, wherein said device includes a housing in which the actuator is mounted for axial reciprocation between the positions of engagement and disengagement with the valve, including adjustable means for preventing said actuator from movement to the position of valve engagement wherein said adjustable means include apertured slides mounted in the housing and movable to a position wherein the slide apertures are in linear alignment in a plane normal to the axial movement of the actuator, including means external of the housing for manually adjusting the slides and for manually moving the actuator to the various positions, wherein said actuator is spring biased to the position of disengagement and wherein said adjustable means comprise a plurality of parallel coplanar slides movable transversely to the axis of the actuator and having apertures perpendicular to the slide movement, said slides being selectively movable to position wherein said apertures are in coplanar linear alignment perpendicular to the axis of the actuator, said actuator including a transverse projection adapted to pass through said apertures when aligned whereby said actuator can move to a position clearing the slides for an engagement with said valve, each of said slides being movable to other positions obstructing axial movement of said actuator by abutting the said transverse projection.

2. A fuel lock as in claim 1 wherein the slides are arranged symmetrically about the actuator and said external means are external knobs spaced from and movable parallel to a calibrated housing surface.
