APPARATUS FOR MIXING AND CONTROLLING A SUPPLY OF FUEL FOR EXPLOSION- ENGINES.

Application filed July 8, 1918.

ficiency of engines of the internal combus tion type and also means whereby the carbon will be converted into a combustible gas and consumed, with the result that there will be no accumulation of carbon in the cylinders and the efficiency of the engine will be reatl increased, whereby the amount 0? wor or mileage for a given quantity of gas or fuel will be materially increased, and with the further result that no obnoxious gases will be discharged from the exhaust.

To the'attainment of these ends, and the accomplishment of other new and useful ob- 'ects as will appear, the invention consists 1n the features of novelty in substantially the construction. combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompan ing drawing illustrating this invention an in whichi Figure 1 is a view, partly side elevation, partly in section, and with parts broken away of an automobile havin an attachment constructed in accordance with the principles of this invention ap lied thereto.

Fig. 2 is a detail sectional v ew taken on line 2-2 Fig. 1.

In the drawing the apparatus has been shown as being applied to an automobile, but it is to be understood that it may be applied and used for other purposes, and therefore, it is desired that the drawings herewith submitted shall be considered as being merely diagrammatic.

Referring more particularly to the drawing, the numeral 10 designates an engine cylinder having the usual intake manifold 11 and the exhaust manifold 12.

The usual radiator 13 is also provided and the radiator may be supplied with an overflow 14, althou h such overflow is not necessary with t 1e present invention. The

radiator contains a supply of water which may, if desired, have mixed therewith, kerosene or other hydrocarbon or combustible fluid.

A pipe 15 has communication with the interior of the radiator 13, and the inlet 16 of this pipe is disposed at a point above the water level of the radiator. The pipe may be of any desired size and may be coiled about the exhaust manifold 12 as at 17, one. portion of the pipe may be held in contact with the exhaust manifold in any suitable manner. The other end 1214 of this pipe has communication with a valve structure which latter comprises a casing 19 which is connected with the intake manifold 11 so as to have communication with the opening 20 in the manifold, through the medium of the opening 21 in the valve casing, and in which casing there is provided a valve 22, preferably of the rotary type which, when adjusted, establishes communication between the opening 20 of the manifold 11 and a casing 23 which is connected with the valve casing 19. I

he end 18 of the pipe 15 has communication with the casing 23 on one side of a partition 24 and which partition divides the casing 23 into two chambers 25-26, the chamber 25 constituting an inlet chamber and the chamber 26 constituting a valve chamber in which latter is arranged a valve 27 which is mounted upon a stem 28. the latter preferably having a threaded portion 29 engaging in a bearing 30 and the valve 27 is adapted to cooperate with the valve seat 31 to open and close communication between the chambers 25-26. The valve stem 28 also has a bearing in a suitable guide 32 and aspring 33 encompasses the stem with the one end bearing against the valve 27 and the other end against a shoulder 34 on the stem 28 and which shoulder may be in the form of a pin, so that the 5 ring 33 tends normally to seat the valve 2 upon its seat 31. The stem'28 may be provided with a handle 35 by means of which the stem may be adjusted with respect to the bearing 30 to va the tension of the spring 33.

l hen the valve 22 is open, the suction in the engine will be manifested in the chamber 26 of the valve casing, and this suction will unseat the valve 27 so as to also menifest itself in the pipe 15. The sn' on thus created will draw the steam vapor from the radiator 13 and this vapor will be delivered into the intake manifold 11 through the valve 22 and which valve maybe no crated in any desired or suitable manner such as by means of an operating handle 36 located in a convenient position to the operator, such as upon the steering post 37, and the handle 313 may be connected with a flexible member 3H movable in a housing 39. and which flexible member 2% is connected with an operating; handle ill on the valve 22. The vapor thus drawn in through the pipe 15 will mix with the gas being discharged into the engine. and the amount of vapor will be coi'itrollcd by the adjustment of the valve 2:, after the tension of the spring 33 has been adjusted. Obviously, the tension of the spring 33 may be varied as desired.

In order to supply outside air to the radiator to replace the vapor drawn from the radiator and to prevent the formation of a vacuum, any suitable means may he provided such as a valve embodying a valve casing 41 which may be connected with the cap 42 of the radiator. This valve 41 is of a construction similar to the valve 19 and embodies a valve chamber l-l ha ring a valve ll therein controlled by a Rjll'ilig'. and the chamber 43 has communication with the outside air through an o 'iening l6, and which opening 46 controlled by the valve 47, and adapted to be adjusted by the han dle -18 in a manner similar to the valve 19.

The valve ll comprises a valve proper 4-9 which ma be operated by means of a flexiblc member 5H having a handle- 51. thereon located in a convenient position for the operator, and, which flexible member operates in a casing 52 and is connected to a. valve handle 53, so that the amount of air admitted into the radiator 13 may be controlled at will. The admission of the air into the radiator will also be automatically controlled alter the valve -l l has been once set and such automatic control is accomplished by the suction created in the radiator to unseat the valve l-T.

Tn order to prevent water of ondensation, which would Form in the radiator by means of the admission of outside air therein, into contact with the steam or vapor, from pass ing into the pipe 15, any suitable means may he provided to prevent such operation, such, for instance. as a balilc plate 54 which may be disposed bet ween the opening of the valve casing 41 and the. in et of the pipe 15.

Obviously. the form ol valve 41 may be varied, and any suitable construction or means may he, provided for admitting the outside air into the radiator, which means is ad ipted to be controlled so as to vary the quantity of air admitted.

It is thought that the operation of this improved apparatus will be clearly HIHlBP- stood from the foregoing specification, but, briefly stated, is as follows:

The tension of the spring controlling valve 47 is first adjusted to suit the climatic and other conditions and the tension of the spring controlling valve 27 may be adjusted as desired in accordance with the quantity of vapor which is desired to be supplied to the charge of fuel, and after these valves have been thus adjusted, the valves 22 and 43' may be controlled at Will through the medium of the operating handles 36-'5l. As the vapor is drawn from the radiator, outside air will mix with the vapor, the mixture being delivered to the intake manifold ll through the pipe 15 and valve 22. When the engine is idling, the mixture of vapor and outside air will not be delivered to the intake manifold because the tension of the spring 33 is such as to overcome the suction in the engine cylinder at that time, but when the engine is working, the increased suction in the cylinder will be sufficient to overcome the tension of the spring 33 and the valve 27 will be unseated.

With this improved construction the formation of carbon in the engine cylinder will be prevented and the life of the engine and the parts will be increased, owing to the fact that bccause of the elimination of the formation of carbon, it will not be necessary to grind the cylinders or valve seats.

Furthermore, the water in the radiator will be maintained at a uniform temperature and the circulation of the Water in the radiator or the quantity of the Water in the radiator will not be, interfered with beyond normal conditions.

Furthermore, by automatically and entircly closing or shutting oil" the vapor and air passage from the radiator, when the engine is stopped, all possibility of the interior of the engine becoming rusted, or the spark plug short circuited will be avoided, with the result that) later, the engine will start when cold, and respond promptly.

By employing a mixture of water and alcohol or kerosene or other hydrixzarbon or ombustible fluid as a cooling medium in the radiator, the vapor from. which mixture is commingled with outside air and delivcrul to the charge being supplied tothe engine, the efficiency of the charge will be greatly increased, with the result that a greater amount of mileage or work can be obtained from a given quantity of the charge, by the mixture of the hydrocarbon, or combustible fluid, vapor and air from the radiator.

While the preferred forms of the invention have been herewith shown and dosrrihed. it is to be understood that various changes may he made in the details of consupplying a greater quantity of.
