chambers and cylinders thereof. The'inven-' tion comprises an apparatus of the general type, as, I am aware, has heretofore been employed for admitting a quantity of water vapor to the intake manifold to be mixed with the carburated explosive mixture before the same is admitted to the cylinders to be therein exploded to drive the engine. In apparatus of this type, that has been brought to my attention, it is customary to merely employ a device by which from the radiator of the engine, or from an independent source, a water vapor is admitted to the intake manifold. In carrying out my invention I have constructed a device which is readily attached to any gasolene motor and is particularly adapted for use in connection with motors of this type employed in motor vehicles, and furthermore, the construction is such that the water vaporalone may be admitted tothe intake manifold, or la mixture of watervapor and atmospheric air may be admitted to the intake manifold, or atmospheric air alone so admitted, or both thewater vapor and the atmospheric air entirely shut off depending of course upon the conditions under which the motor is operated, and the apparatus made in accordance with my invention will be hereinafter more particularly described.

1 In the drawing: I

Figure 1 is a diagrammatic elevation and central longitudinal cross section of the attachment made in'accordance with this invention and applied to a gasolene engine used in a motor vehicle. y

Fi 2 is a front elevation of the valve mom or of the'apparatus, and

Figs. 3,4, 5 and 6 are diagrammatic sections showing the various positions of the valve. Referring to the drawing the cylinders of a gasolene motor arediagrammatically indicated at'lO and the manifold by which the carbureted explosive mixture is admitted is indicated at 11. The radiator employed to cool the circulating water or other medium is indicated at 12 and the usual overflow pipe therefrom is indicated at 13, and. the

dash board of the vehicle is indicated at 14.

In carrying out this invention I employ a valve and gage case 15 fitted with a flange 16 adapted to abut against the face of, the dash board and having a stem 17 which passes through an aperture provided therefor in the dash board, and on the opposite side thereof is fitted with a Washer 18 and a nut 19, turned down on the screwthreaded exterior of the stem 17 so as to maintain the valve and gage case in position on the dash board. In the valve and gage case 15 there is fitted a rotary valve 20. This terminates in a stem 21 and a knurled disk 22 by which the valve may be rotated and the valve is maintained in position in the valve and gage case by a cap 23. In a suitable position the valve is provided with a transverse passage 24 adapted to register when the valveadapted to register with a port 29 provided therefor in the body of the valve and gage case adjacent the port 26 and. the bore 28 communcates with the bore 30 in the stem 17. v

The valve and gage case 15 is provided with a mixing chamber indicated at 31 and inclosed by a gage glass 32 there being an opening. 33 in the wall of the valve and gage case so that the interior of the mixing chamber may be viewed through a portion of the glass tube 32. The glass tube 32 is maintained in position and the mixing chamber closed by a cap 34 turned down to position on the screw threaded extremity of that portion of the valve and gage case inclosing the mixing chamber, and this cap 34 is provided with a tubular extension 35.

I also employ a pipe 36 one end of which is in communication with the bore 30 in the stem 17 and is connected to this stem by a of the pipe 36 passes through the wall of the radiator and terminates in a bend with the orifice facing downwardly beneath the radiator cap 38. I also employ a pipe 39 one end of which communicates with themixing chamber by means of the extension 35 to which this end of the pipe 39 is secured by means of a cap or nut 40 or otherwise, whilethe opposite end of the pipe 39 is secured in the intake manifold 11 preferably at the point where the same divides so as to communicate with the different cylinders of the engine.

The valve and gage case 15 adjacent the flange 16 or otherwise, may be provided with a disk 41 revoluble therein. and set eccentrically to the axis of the valve and provided with a port 42 adapted to register with the orifice of the bore 28. Also as indicated in to Fig. 1 of the drawing, the valve and gage case may be fitted with a shiftable sleeve 43 provided with a port 44 so as to cover and uncover to any desired extent the inlet port in the wall of the valve and gage case.

In the. use of the hereinbefore described apparatus as will be readily understood, when the valve is in the position shown in Figs. 1 and 3, and the disk 41 and the sleeve 43 placed so as to have the ports therein register respectivelywith the bore 28 and the port 25, the water vapor from the radiator will be caused to flow-through the pipe 36, through the stem 17 and the bore extending.

28, and the then downwardl branch of the angular passage 2 to the mixing chamber 31. Atmospheric air will also be admitted through the port 25, the passage 24, and the port 26, to the mixing chamber 31, and the air and water vapor thus admitted will pass by way of the pipe 39 to the interior of the intake manifold where they will commingle with the carbureted explosive mixture before the same is taken into the cylinders of the engine. When the valve is given a quarter turn clockwise the ports therein will assume the position shown in Fig. 4 in which, as will be readily apparent, the water vapor as well as the air are entirely out off. When given another quarter turn in the same direction the passages in the valve assume the position indicated in Fig. 5 in which as will be understood, atmospheric air alone is admitted to the mixing chamber and into the intake manifold. When given another quarter turn in the same direction the passages in the valve assume the position shown in Fig. 6 in which the water vapor alone from the radiator will be admitted to the mixing chamber and to the intake manifold. Experience has demonstrated the fact that in fast driving it is advisable to so place the valve as to admit both the water vapor and the air, whereas in relatively slow driving, better results are obtained if the air is 636 out off and the water vapor alone admitted,

whereas in cases where it is diflicult to start the motor it is preferable to admit the atmospheric air alone. As will be apparent it is. also desirable to have the valve so constructed as to entirely cut oil both the air and the Water vapor, and in many instances it may 1 also be necessary to regulate eitheror both the quantity of the water vapor and the air admitted to the manifold, and from the foregoing description it will be seen that in carrying out this invention I have provided for all these conditions. I claim as my invention:

1 A.gas engine attachment comprising a casi g, and a revoluble valve therein having a longitudinal passage in one end thereof terminating in radially disposed passages,.

each adapted to register with a port in the casing, the said revoluble valve also having a transverse air passage therethrough independent of the aforesaid passages and adapted at its ends to register with ports, the inner of which and also the port with which the radially disposed assages register are in communication wit the manifold of the engine, while the longitudinal passage in the valve is adapted to be connected to a source of water vapor so that the valve may be set for admitting water vapor alone to the manifold, admitting air alone to the manifold, and admitting a mixture of water vapor and air to the manifold.

2. A gas engine attachment comprising a casing having a chamber therein, and a revo luble valve mounted to turn in the said casing and having in one end thereof a longitudinal passage terminating in radially disposed passages at right angles to each other, and each adapted to register with a port in the casing to make communication with the said chamber therein, the said revoluble valve also having a transverse air passage therethrough independent of the aforesaid passages therein, and adapted at its ends to register with ports in the casing, one of which communicates with the atmosphere and the other with the said chamber in the casing, which is adapted to be placed in communication with the manifold of the engine while the said longitudinal passage in the valve is adapted to be connected to a water vapor supply. I

3. A gas engine attachment comprising a casing having a chamber therein, a revoluble valve mounted to turn in the casing and havmg a transverse air passage therethrough adapted at its ends to register with ports in the casing, one of which communicates with the atmosphere and the other with the said chamber in the casing, the said valve being also provided at its inner end with a longitudinal passage terminating in radially disposed passages at right angles to each other, and one of which is parallel with the transverse air passage, the radial passages in the valve being adapted to register with a port in the casing also communicating with the chamber therein, while the said longitudinal passage in the valve is adapted to be con nected to a water vapor supply, and thechamber in the casing to the inlet manifold of the engine, and means slidable on the easing determining the extent to which the air inlet port therein is opened to control the admission of air to the chamber in the 1 casing.
