VAPORIZER FOR INTERNAL-.COMBUSTION ENGINES.

Application filed October 15, 1921. Serial No. 507,992.

To all whom t may concern:

Be it known that I, JAMES H. PLAGE, a citizen of the United States, residing at Warren, in the county of `Warren and State of Pennsylvania, have invented certain new and useful Improvements in Vaporizers for Internal-Combustion Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in va-porizers for internal combustion engines, and has for its object to provide a vaporizer which is automatically controlled, compact and simple in construction, requires no special fittings and can be used on the engines of any automobile.

Another object of my invention is to provide a vaporizer adapted to be secured to the side of the exhaust manifold of a gasoline engine, thereby being automatically heated.

A further object of my invention is to furnish a vaporizer which is adapted to receive a constant supply of water from the water jacket of the motor, thus insuring steam, which is far more practical than using cold water or moist air from tanks, reservoirs, or from the radiator of the car.

By the use of this device, the formation of carbon is minimized and a smoothly running engine is assured.

A still further and desirous improvement` of my vaporizer, is that it greatly decreases the vibration of the motor, due to the constant and steady amount of fully vaporized fuel admitted to the combustion chamber 0f each cylinder, thus causing a smooth running motor.

All of the above objects and improvements have been proved to be accurate facts by many successful tests.

With the above and other objects in view, which will appear as the description proceeds, the invention consists in the novel features herein set forth, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

Referring to the drawings, numerals of like character designate similar parts throughout the several views, in which- Fig. 1 is a view of my improved vaporizer in place on an automobile engine.

Fig, 2 is a cross section in detail of the vaporizer, and

Fig. 3 is a view taken on line 3-3 ofV Fig. 2.

In the drawing 1 designates any automob1le engine, 2 is the exhaust manifold of said engine, to which is secured the main body or vaporizing chamber 3, of my improved vaporizer. The vaporizing chamber is secured in place vby means of a stud l1, which is threaded and screwed in the recess 20 of the chamber and then in the exhaust manifold 2.

4 represents the water inlet fitting, which is provided with a screw adjustment 5, which allows approximately fifteen drops of water per minute to spray against the hot walls 10 of the vaporizing chamber 3. This chamber receives its heat from the exhaust manifold.

By means of the tube 6, the chamber is connected to the water jacket 7 of the motor, thus receiving a supply of pre-heated water or vapor.

8 represents the air inlet, provided with a ball and spring check 9 which automatically regulates the supply of air.

The vapor is delivered from the chamber 3 to the inlet manifold 15 by means of a tube 14 and a cock of any desired type 13, which is secured to the chamber at 12.

To overcome the accumulation of water in the vaporizing chamber when the car is not in motion, l provide the device with an outlet 17 including a spring and ball check 18, the ball being drawn up against the spring by the suction, when the motor is started, enough to allow the accumulated water to escape.

The operation of my device is obvious. A constant iiow of heated water or vapor comes from the water jacket of the motor, and is sprayed against the inner walls of the vaporizing chamber, and mixed with the air supply, which is automatically regulated by ball and spring checks. This mixture is then admitted into the intake manifold and comes into contact with the gasoline vapor and breaks up any unvaporized particles of the fuel, thus minimizing the deposit of carbon and assuring a smoothly running engine.

From. the foregoing, I believe that the construction, operation and advantages of my device mav be clearly understood without further description, and in conclusion I may state that the constructional details may be modified considerably Without departingv from the spirit or' the invention, as set forth in the following,` claims.

lVhat l claim and desire to secure by Letters Patent is i l. The combination with means for iurnishing' a. mixture of air and steam to the intake conduit of an internal Combustion engine, including` a substantially discshaped vaporizing` chamber, of a stud carried by one of the flat faces of said chamber and adapted to be fitted to the exhaust manifold of the engine so that one Y0f Jthe flat faces of said chamber will be opposite the engine.

2. Means for furnishing a mixture of air and steam to an internal combustion engine comprising a vaporizing chamber cylindrieal in cross section and provided with two diametrically opposite ports in its circumference, one of said ports being an air inlet and the otherva water outlet and both being fi ted with check valves, tWo additional diametrically opposite ports, means to connect one of said ports to a Water supply and means t0 connect the other of said ports to the intake manifold of said engine, Valves litted adjacent both said last named ports7 said chamber being` provided with a stud, by means of Which it may be secured to the exhaust manifold of an engine, and thereby heating;` said chamber.

3. The combination as claimed in claim l, wherein the vaporizing chamber is provided with thick walls, adapted to retain the heat from the exhaust manifold.

n testimony whereof I aiiix my signature.
