Abstract

This invention consists of a mechanism adapted to be connected into the fuel line of an internal combustion engine of a vehicle between the fuel tank and the fuel pump, the aforesaid mechanism consisting of a two-piece vertically disposed metal receptacle that has its two sections screwed together on assembly. The uppermost one of the two piece receptacle contains an electric solenoid that is connected to an electric battery and to a signal receiver that receives its impulses from a transmitter located in another vehicle. The solenoid has a spring-loaded plunger that has its lower end extending down through a seal in the bottom of the uppermost one of the two-piece receptacle and on into openings in the wall of a horizontally disposed Y-shaped tube that is located in the lowermost one of the two-piece receptacle. The side of the lower portion of the plunger has an opening therein through which fuel will flow when this invention is inactive; the lower end of the plunger is adapted to enter an opening in the wall of the angularly disposed portion of the Yshaped tube. This invention also has a blinking light connected to the aforesaid signal receiver in such a location as to be seen outside the vehicle containing this invention.

Claims

1. A remote control for cutoff of the flow of fuel through the fuel line of a motor vehicle, comprising a manually operated radiant energy signal transmitter, a radiant energy receiver on said motor vehicle to receive energy from said signal transmitter, electrically operated mechanism connected to the output of the signal receiver for cutting off the flow of fuel through said fuel line when said signal receiver receives a signal from said signal transmitter, said mechanism comprising a metal receptacle having a screen bottom, an electric solenoid secured to the underside of the top of said receptacle, a horizontally disposed Y-shaped tube in the lower portion of said receptacle, one end of said Y-shaped tube connected to the fuel tank of said vehicle, the other end of said Y-shaped tube connected to the fuel pump of said vehicle, the third opening of said Y-shaped tube is angularly disposed toward the said screen

2. The apparatus of claim 1, wherein said solenoid is provided with a vertically disposed spring-loaded plunger having an opening in the side of the lower portion thereof, the lower end of the said plunger slidably passing through an opening in the center of the said Y-shaped tube and at a right angle to the said Y-shaped tube and down through the opening in the upper wall of the angularly disposed portion of the said Y-shaped tube when the said apparatus has been activated to shut off the fuel of the said internal combustion engine.

3. The apparatus of claim 2, wherein the said signal receiver is provided with a blinking light that is located on the exterior surface of the said vehicle having the said signal receiver therein, the said blinking light going on when the said apparatus is activated.

4. The apparatus of claim 3, wherein the receptacle is in two parts, one above the other, the lower portion of the upper part is in threaded engagement with the upper portion of the lower part.
