FUEL-LOCKING MEANS.
ASpecification of Letters Patent.
Patented Mar. 19, 1918.
Application filed February 16, 1917. Serial No. 148,945.
To all whom z't may concern:
Be it known that I, HERMAN RUDOLF SACK, a citizen of the United States', residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Fuel-Locking Means, of which the following is a specification.
My invention consists of improved locking means for preventing the flow of fuel, such as gasolene or gasolene vapor, to internal combustion engines of automobiles or the like.
Prior to my invention numerous devices have been invented with the object of locking the gasolene in the pipe between the reservoir and the carbureter. However, in most instances the constructions are such that the pipes or conduits connecting the locking devices with the carbureter can be easily cut and either joined to the gasolene reservoir or the cut pipe leading to the carbureter can be attached toa can of gasolene, thus enabling any one, who intends to steal the automobile, to operate the engine.
One object of my invention is to provide lmeans which will be affected by the stopping of the engine to automatically stop the flow of fuel to the engine to prevent the latter from being again started by an unauthorized person.
Another object is to so construct my invention that no one other than an authorized person with the proper key can unlock the fuel locking means after the engine has stopped.
A further object is t0 so make my invention that the exhaust from the engine will keep certain valve mechanism open to admit the fuel to the engine.
Another object of my invention is to so construct certain of the parts that they will prevent leakage of the gasolene into the locking mechanism.
Another object is to provide means for locking the gasolene vapor adjacent the outlet of the carbureter and the manifold which leads to the engine.
A still further object is 'to so design my invention that it will be of sim le construetion, durable, and can be manu actured at a comparatively low cost.
These objects, and other advantageous ends hich will be described hereinafter,- I attai l in the following manner, reference being had to the accompanying drawings in which- Figure 1 shows a fragmentary elevation partly in section of my invention and includes a valve which will be held open by the pressure of the exhaust gas from the engine and which automatically closes when the engine stops.
Fig. 2 is a section on the line 10-10 of Fig. l.
In my invention as shown in the drawing a manifold 59a, leading from the outlet 46 of the carbureter to the engine, has a valve 60 rotatably mounted therein and also has an extension 61 thereon designed to engage a forked end 62 of a rod 63. The rod 63 forms an extension of a lock 64 which in the present instance is key-operated. The lock 64 can be of any of the various types now on the market and includes means which, when moved by the turning of the key, will rotate lthe rod 63. The valve 60 also has a cylindrical extension 65 which projects entirely through the manifold and has secured to it a crank arm 66. This crank arm is connected by a link 67 to a piston rod 68, the latter being connected to a piston 69 which operates in a cylinder 70. The upper end of the cylinder 70 communicates with the engine exhaust pipe 71. A coiled spring 72 is interposed between the bottom of the piston 69 and the cylinder 70 and acts to raise and normally hold the piston 69 so as to keep the valve 60 closed and thereby prevent the passing of the gasolene mixture from the carbureter to the engine.
To start the engine, the key is inserted and turned in the lock 64. This action opens the valve 60 and lowers the piston 69, thereby compressing the spring 72. When the engine starts, the pressure of the exhaust through the pipe 71 holds the piston 69 down and consequently holds the valve 60 open.
I preferably provide the exhaust pipe with an inwardly projecting extension 73 for defiecting a portion of the exhaust into the cylinder, and thereby insure sufficient pressure on the top of the piston 69 to keep the valve 60 open.
When the engine stops, the pressure of the exhaust is removed and the sp-ring 72 acts to raise the piston and automatically close the valve 60. I preferably inclose the crank arm 66, link 67, and piston rod 68 in j a casing 74 which may be made of any de- I conduit for the fuel to an internal combus sired form, and preferably made in two sections as illustrated in the drawings. This casing serves to protect the movable parts between the piston 69 and the valve 60, so that it is impossible to manually move the valve 60 by any means other than the proper key for the lock 64.
While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof., and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. The combination of a valve for cutting 0H the supply of fuel to an internal combustion engine, a lock for manually opening said valve, and automatic means for closing the valve and normally held against action by the exhaust of the engine, substantially as described.
2. The combination of a valve for cutting olf the supply of fuel to an internal combustion engine, a lock for manually opening said valve, automatic means including a cylinder and a piston therein, and means for directing the exhaust of the engine against the piston to move and hold the valve in an open position, substantially as described.
3. The combination of means forming a conduit for the fuel to an internal combustion engine, a valve interposed in said conduit, a lock operatively connected to and for manually moving said valve, actuatin means operatively connected to said valve an acted upon by the exhaust from said engine to hold said valve in an open position, and means for moving said latter means and operated, when the exhaust from the engine is discontinued, to close said valve, substantially as described.
4. The combination-of means forming-a tion engine, a valve interposed in said conduit, a lock operatively connected to and for manually moving` sald valve, an extension on said valve, a cylinder communicating with the exhaust pipe of the engine, a piston in said cylinder, means operatively connecting the piston with the extension on said valve whereby the pressure of the exhaust holds the valve in an open position, and means operative to move said piston, when the exhaust from the engine is discontinued, to effect a closing movement of said valve, substantially as described.
5. The combination of means forming a conduit for the fuel to an internal combustion engine, a valve interposed in said conduit, a lock operatively connected to and for manually moving said valve, an extension on said valve, a cylinder communicating with the exhaust pipe of the engine, a piston in said cylinder, a crank arm on said extension of the valve, a piston rod connected to said piston, means operatively connecting the piston rod with the crank arm, and means automatically operative to move said piston when the pressure of the exhaust from said engine is discontinued, said means acting to close said valve, substantially as described.
6. rIhe combination of means forming a conduit for the fuel to an internal combustion engine, a valve interposed in said conduit, a lock operatively connected to and for manually moving said valve, an extension on said valve, a cylinder communicating with the exhaustpipe of the engine, a z
piston in said cylinder, means operatively connectingthe piston with the extension on said valve whereby the pressure of the exhaust holds the valve in an open position, means' operative to move said piston, when the exhaust from the engine is discontinued, to effect a closing movement of said valve, and means in the exhaust pipe of said engine for directing a portion of the exhaust against the piston within said cylinder, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
