VAPOR SUPPLY MEANS FOR INTERNAL COMBUSTION ENGINES Filed Nov. 19, 1928 Inventor Patented June 24, 1930 CHRISTIAN L. SMITH, F AKRON, OHIO, ASSIGNOR OF ONE-HALF TO VICTOR J.

ROBINSON, 0F AKRON, OHIO VAPOR-SUPPLY MEANS FOR INTERNAL-COMBUSTION ENGINES Application filed November 19, 1928. Serial No. 320,451.

My invention relates to a device for association with the manifold of an internal combustion engine and refers more particu larly to an attachment for supplying moist air or vapor from the radiator to the manifold.

It is a known fact that an internal combustion engine operates more efiiciently when the air is laden with moisture, indicating that the mixture of gas and moistened air is the proper mixture for the most perfect combustion.

To this end I provide an attachment associated with a manifold of an internal combustion engine above the carbureter and means for operating said device when the engine is accelerated thereby, and producing the proper amount of moisture and bringing about a perfect mixture in the manifold,

99 resulting in a saving of gas, quicker acceleration, increases its spark, and smoother operation of motor.

It is an important object of my invention to provide a novel arrangement of parts within a casing having positive action to bring about the results tabulated above in a very eflicient manner.

Other objects and advantages will become apparent during the course of the following description of the preferred embodiment of my device.

In the accompanying drawings:

Figure 1 is a side elevation of an internal combustion engine showing my device ap- 33 plied to the manifold thereof,

Figure 2 is a vertical cross sectional view of my attachment, and

Figure 3 is a detailed section of the trap.

Referring to the drawings numeral 10 4o designates an automobile engine of conventional type. The engine 10 is provided with a usual intake manifold 11 having an L-shaped coupling 12 in direct association with said intake manifold 11.

As shown more clearly in Figure 2, my

invention consists of a hollow body 13, having a screw threaded nipple 14 at its upper end for engagement with said L-shaped coupling 12 and at its lower extremity in 5 screw threaded relation as at 15 a sleeve 16.

The sleeve 16 affords a guide for the plunger 17, normally urged upward by coil springs 18, said spring hearing at its opposite ends against a shoulder 19 in the sleeve 16 and an abutment 20 on said plunger 17. Disposed within the nipple 1d and complementary to a valve seat 21 within said nipple 14 is a needle valve 22, tapered to provide proper fitting within the valve seat 21, said needle valve disposed at the upper 0 extremity of said plunger 17 and operable through the valve seat 21.

At the side of the body 13 is an inlet port 23, to which by a union 24 is attached one end of a conduit 25, the opposite end of whichis located in the filling spout of the automobile radiator 26.

At the lower end of the plunger 17 is a socket 27 adapted to receive an adjustingv screw 28 and held in rigid position within said plunger by means of a lock nut 29.

A connecting member 30 is suitably secured to the head of'the adjusting screw 28 and is adapted to be connected with the butterfly valve 31 of the carbureter. f,

It will thus be seen from the foregoing description that when the plunger 28 is drawn downwardly within the body 13 by suitable means connected to the throttle valve, moisture laden air from the radiator is introduced into said body and while the plunger remains in this position, the un seating of the needle valve 22 within the nipple 14 will permit the moisture laden air to pass through said nipple and become a part of the gaseous mixture within the manifold 11.

Conversely, whenthe plunger 17 is not depressed, the coil spring 18 will force the needle valve to become seated and stop the flow of the moisture laden air to the intake manifold. r

I have therefore provided a device wherein the relative proportions of the moisture laden air and the explosive mixture can be positively regulated for the most perfect mixture by the proper placement of said adjusting screw within said plunger and the flow of vapor definitely cut off by the seating of the needle valve within the nipple 14:.

In the preferred embodiment of my invention a trap 32 is provided in association with the arcuate 25 between the intake manifold 11 and the automobile radiator 26', said trap 32 consisting of a chamber 33 having openings on opposite sides of the chamber 33 to receive the depending ends 34L of the conduit 25. In the operation of my device it will be seen that said trap 32 prevents the condensation from reaching the intake manifold 11 but permits the vapor to freely pass through the conduit 25 to the said intake manifold 11.

It will be obvious also, that I have devised an attachment for an internal combustion engine which is exceedingly simple in construction, controlled by the driver and in such manner that the degree of acceleration predetermines the amount of moisture laden air for the proper charge with respect to the gaseous mixture in the manifold of an automobile.

I desire it to be understood that I may make changes in the construction, and in the combination and arrangement of parts, provided such changes fall within the scope of the appended claim.

Having thus described my invention, what I claim as new is: A

In a water vapor supply means for an internal combustion engine, wherein the engine includes a radiator and a carbureter; a hollow body having an inlet port, and an outlet port, the outlet port being provided with a valve seat, a sleeve connected to and depending from the lower end of said hollow body directly below and in longitudinal alignment with the outlet port, a pipe for establishing connection between the radiator and the inlet port, a plunger disposed longitudinally within said hollow body and sleeve and depending below the same, a needle Valve at the upper end of said plunger for said seat, a coil spring urging said needle valve on its seat, and an adjusting screw carried by the lower extremity of said plunger, and a connecting member from said adjusting screw to the butterfly valve of the carburetor to cause a downward pull on the plunger and needle valve to unseat the same to admit vapor from the radiator and the inlet port to the outlet port and the intake manifold.

In testimony whereof I affix my signature.

CHRISTIAN L. SMITH.
