AUXILIARY FEEDING DEVICE FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Fatent.

Application filed September 15, 1917. Serial No. 191,52

To all whom it may concern:

Be it known that I, JEAN B. BEnooUoxoox, a citizen of the United States, and

a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Auxiliary Feeding Devices for Internal- Combustion Engines, of which the following is a. specification.

My invention relates to the feeding of engines of theinternal combustion type and more particularly to an auxiliary device that is connected to and discharges a suitable vapor into: the intake manifold of a gasolene engine. lhe objects I have in view are to provide a feeding device of this character that is both simple in construction and easy to manipulate and is also one that comprises few parts so that it may be economically manufactured and can be sold for a moderate price. It is also an object of my invention to provide suitable means whereby the quantity of vapor discharged from the device may be regulated or adjusted to anicety and may be turned on or cut ofi whenever desired. Owing to the construction and arrangement of the parts of my device, I am enabled to attain divers results from its operation. For example, the vapor discharged into the manifold by my device may be charged with Water or gasolene for the purpose of modifying the gaseous mixture from the carburetor, or for the purpose of. cleaning the pistons and cylinders, etc., the vapor may be charged with kerosene or a carbon removing compound,-in fact, any suitable liquid may be placed in the reservoir of my device and the vaporized mixture fed to the manifold.

I prefer to accomplish the objects of my invention by substantially the mechanism hereinafter described, whereof a diagrammatic illustration is disclosed in the accompanying drawings that form a part of this specification, wherein,-

Figure 1 is an elevation of my device attached to the manifold of an internal explosive engine, the latter being shown in a Referring to the drawings, it will be seen my invention preferably comprises a cylindrical chamber or reservoir 5 that consists of a tube or hollow cylinder of glass or other suitable material, the ends whereof are closed by caps 6 and 7, having flanged edges that extend over the sides of the tube. The

ratemea a 8, rate. r

lower cap 6 has a screw-thread connection with a post 8, that arises vertically from the center thereof and extends axially through chamber 5 where it is screwed into an internally and externally threaded, boss 9 tube and the interior surfaces of the caps in order to prevent leakage and to avoid breaking the glass. A pair of clamping nuts 11 are screwed onto the exterior threads of boss 9 in order to clamp the device to a suitable bracket or other support 12, whereby the feeding device may be conveniently mounted adjacent the manifold of the engine. The upper end of post 8 is bored to provide an L-shaped passage .rG the shorter or lateral portion .2? whereof opens into the chamber 5, adjacent the top thereof or above the liquid level, while the longer vertical portion G of said passage conununicates with the boss 9 or the top of cap 7.

Adjacent the boss 9 isan air inlet device that consists of a pipe 13 that is enlarged and threaded adjacent'its upper end and tapped into a threaded boss 1 f also arising from the upper surface of the top cap 7. The lower end of pipe 13 is cut obliquely, as shown, and terminates adjacent or above the bottom of chamber 5 in order that its end will be immersed in the fluid or liquid that is contained in said chamber, while the opposite or upper end ofv said pipe is provided with an inlet cock 15, the adjustment of which latter regulates the quantity of air admitted to the chamber 5.

A suitable elbow 16 is tapped into the outer end-of the bore of boss 9 and has its lateral member connected by means of a sleeve nut 17 to a suitable discharge pipe 18, with which it communicates. One member or branch of an elbow 19 is connected by a sleeve nut 20 to the opposite end of discharge pipe 18, while the other branch or member of said elbow is tapped into a suitable threaded inlet opening made in a convenient portion of the manifold B of theengine A. In order to permit the discharge of the vapor from the chamber into the manifold and to prevent back pressure reaching the chamber 5, I have provided a suitable check valve 22, which I have shown as being disposed upon the elbow 16, but it will be understood it may be mounted at any convenient place in the discharge passage between the chamber 5 and the manifold.

In operation, the chamber 5 is filled with a suitable liquid by removing the air inlet device, and after the cylinder has been filled to a suitable height, said inlet device is screwed into position again and the cock 15 is adjusted to permit air to enter therethrough and into the chamber. The suction from the manifold will cause the air to bubble or surge through the liquid from the lower end of pipe 13 and rise or pass out of the liquid charged with a vapor, where it will be drawn off through the L-shaped passage mG that is located above the level of the liquid. The vapor will then be drawn through pipe 18 past the check valve and into the manifold. When kerosene is used in the chamber 5, the vapor produced by the bubbling of the air through the same will be utilized in cleaning the valves and pistons of the engine, and likewise when the cham- .ber is filled with carbon remover, the vapor therefrom will assist in keeping the'cylinders of the engine free of carbon accumulations. In fact, the device may be employed for modifying the feed in any manner through the graduated control of the introduction of air or vapor.

It will be understood that I do not limit myself to the precise structure disclosed herein, for it is obvious that divers modifications may be made without materially departing from the spirit of my invention. All such changes are contemplated within the scope of my invention as expressed in the appended claims.

What I claim is 1. An auxiliary feeding device for internal combustion engines comprising a cylinder, closures for the ends of said cylinder, means extending between said closures adapted to clamp them upon the ends of said cylinder, said upper closure having an outlet passageway therethrough and an inlet port, a pipe mounted in said inlet port and extending from adjacent the bottom of said reservoir to the outside of said upper cap, a regulating cock on said pipe outside said reservoir, and means for establishing communication between the outlet port in said upper cap and the inlet manifolds of the engine.

2. An auxiliary feeding device for internal combustion engines comprising a cylinder, caps closing the ends of said cylinder, a central post having threaded connections with said caps, said post having an L- shaped passage leading from adjacent the lower face of the upper. cap to the exterior of said cylinder, a port in said upper cap, a pipe mounted in said port and extending from adjacent the bottom to the outside of said cylinder, a regulating cock on said pipe outside of said cylinder, a hollow stub on the upper surface of said upper cap and communicating with said L-shaped passage, bracket clamping nuts threaded on said stub, a discharge pipe screwed into said stub and establishing communication between said L- shaped passage and the manifold of the engine, and a check valve in said discharge pipe adjacent its connection with the manifold.
