Specification of Letters Patent.

Application filed June 8, 1916. Serial No. 102,417.

To all whom it may concern:

Be it known that 1, JOHN G, Ynisna, Jr, citizen of the United States, residing at Omaha. in the county of Douglas and State of Nebraska, have invented certain new and useful Improven'ients in Feed-Controlling Means for lnternal-Combustion Engines, of which the following is a specification.

This invention relates to feed controlling means for internal combustion engines, adapted for use in connection with all engines of this class, movable or stationary, and found to be particularly useful for the engines of automobiles, and has for its object, broadly, to provide such an arrangement of parts that superheated steam may be introduced to the fuel intake in greater or lesser quantities, as may be required for varying speeds, weight of the load, or moving upon inclines, the use of the superheated steam resulting in economizing fuel, and the substituting of superheated steam for cold air for mixing with hydrocarbon, this being particularly of advantage during cold. weather, also for preventing adhesions of carbon within the cylinders and. valves which communicate with the cylinders, and resulting, generally, in increasing the editciency of the engine.

The invention includes a construction of parts, whereby hot water, by operationpf suction, will be removed from the water jacket or other source of supply, and will be moved through an indicator on the dash board or other support convenient to the driver or operator, to an elevation which will beabove the water jacket or other water supply, and from the indicator will be moved through a coil in the exhaust manifold where it will be exposed to a high degree of heat, and from thence will be conducted and will be discharged within the intake manifold, suitable means being provided for a control of this supply.

The invention also includes means found to be of advantage for introducing superheated steam to the intake manifold which is operated in. conjunction with the valve of the carbureter, and which provides adjustmerits so that theproportion of superheated steam supplied may be greater or less, as ma j be required. The invention alsohas reference to such a construction of parts that operation, for the most part, will be automatic, and may be readily applied to the engine at the factory when first assembled or at any time thereafter.

With the foregoing objects in view and others to be mentioned, the invention presents a novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawing. wherein,

Figure l is a view in side elevation of an engine and parts of an automobile, showing the device applied thereto, parts being broken away, and the dash board of the automobile being in section. Figs. 2, 3, 4, 5 and 6 show enlarged details. Fig. 2 is a front view of an indicating device. Fig. 3 is a sectional view on line 3 3 of Fig. 2. Fig. 4 is a sectional view on line 1 4 of Fig. 2. Fig. 5 is a view in longitudinal section of a strainer-plug. Fig. 6 is a view. in longitudinal section of an apertured distributingplug.

Referring now to the drawing, numerals 7 and 8 respectively indicate the cylinders and water jacket of an internal combustion. engine, the carbureter, intake manifold and exhaust manifold of the engine, respectively being indicated at 9, 10 and 11.

At 12 is indicated a sight-indicating device which is mounted upon the dash board 13 at any suitable altitude abovethe water jacket or other source of water supply. While I do not wish to limit myself to any particular form or arrangement of an indicating device, it preferably consists of a suitable casing 14 provided with a transparent part 15 and with a horizontal compartment 16 having an intake .17 and upon which may be mounted a water conducting pipe 18 which communicates with the water jacket 8 and said intake 17 a plug 19 being provided for and inserted in a suitable aper ture (not shown) in the water jacket, said plug 19 being provided with a suitable strainer 20 (Fig. 5.) to prevent sediment from passing to the conducting pipe 18.

The casing is also provided with a pas sageway 21 (Fig. 3.) communicating with the compartment 16 and with its main chamber 22, said passageway being under control of a needle valve 23 which may be conveniently adjusted to permit water to drip from a depending nipple 24: through the main chamber andto pass to a second conducting pipe 26 provided with a coil 01 disposed in the exhaust manifold 11, and

having a part 7) extending from the exhaust manifold to communicate with the intake incoming superheated steam so that it will with the main chamber 22 of the casing by become immediately mixed with hydrocarbon.

. The casing 14 is also provided with a second passageway 29 (Fig. 4.) which communicates with the compartment 16 and passing through a depending nipple 24, said passageway 29 being controlled by a needle valve 30 which is provided with an arm 31 having apertures 32 formed therein at longitudinal intervals.

The conventional gas-throttle-rod for controlling the movement of. hydrocarbon from the carbureter to the intake manifold is indicated at 33. Numeral 34 indicates the conventional valve for the carbureter, the pivotally connected links which form a connection between the lower end of the rod 33 and the lever c of said valve, being indicated at 35 and 36.

In order that the superheated steam, produced by the arrangement of parts as described, ma be supplied to the intake manifold coinci ently with the supply thereto of hydrocarbon through the valve 34 of the carbureter, I provide for the rod 33 a crank-arm 37 and also provide a link or rod 38 having its respective ends pivotally connected with the crank 37 and engaging in one of the apertures "32 of the arm 31 of the needle valve 30. 7

As described, it is obvious that an operator, when imparting the usual limited movement to the rod 33 by use of its handle (Z for its rotation to open the valve 34 for permitting hydrocarbon to enter the intake manifold, will also move the crank arm 37 for opening the valve 30, and a reverse movement of the rod 33 will cause the valve 30 to move to its seat. Also if the link 38 engages in one of the apertures 32 of arm 31 comparatively near the valve 30, the degreeof rotation of said valve will, obviously, be greater than would be caused by an engagement of the link in an aperture more remote.

In operation, a limited quantity of hot water or steam will be elevated to compartment 16 by suction, and on account of suction will move to and through the coil a subject to the means for control mentioned. The water or steam which enters the coil will, of course, be subjected to a high deree of heat, and will enter the intake maniold as superheated steam. On account of the construction as described, the superheated steam will be immediately divided and will be mixed with the hydrocarbon so that ignition will occur to advantage thereafter.

The valve 23 may be adjusted to permit a limited, uniform quantity of water to pass from the compartment 16 to the pipe 26, and this valve is never closed. Water will not pass this valve except by action of suction, and flooding of the intake manifold with water while the valve 23 remains open is quite impossible since it is disposed at an elevation above the water supply or water jacket As soon as the engine commences to operate, there will, of course, be an operation of suction, and hot water will begin to pass the valve 23.

When a heavy load is being drawn or when moving up an incline, and a greater quantity of hydrocarbon is required. it is obvious that the construction provided is of great advantage, since, by the arrangement described, the quantity of superheated steam supplied to the intake manifold will be in proportion to the quantity of hydrocarbon supplied thereto.

It will be appreciated that some advantages are to be derived by connecting the conducting pipe 18 with the water jacket, but I do not wish to limit myself in this respect, and the water may be supplied from any other desired container having a water level lower than the height to which water may be conducted by the pipe 18, to prevent an overflow through the normally open valves 23 and 30. Also the device would be operative without the visible features provided by the casing 14 and members 15. 24: and 24:, and one of the valves 23 or 30 could be dispensed with, and, in each instance, the device would be fairly operative, and the specific construction for members 19 and 28, and many minor details could be changed, within the scope of the claims. What has been shown and described relates to the preferred construction and constitutes one embodiment, only, of the invention.
