y bureters, of which the following is a speciication.

VMy inventionv relates to improvements in carbureters, and one application of it is illustrated in the accompanyi wherein Figure 1 lis a section bureter; Fig. 2,a section along the line 2-2 of Fig. 1.

g drawings,

' Like parts are indicated by the same let' ter in all the figures.

The sly'rell, A having the ends A1, A1. and top A3 makes with the Wall Afthe carburetf ing or mixing chamber A5.

l is a hydrocarbon or fuel nozzle controlled by the valve B1. C is a similar Water or liquid nozzle, both of them discharging into the carbureting or mixing chamber A5.

D is `a mixture discharge port in the end A1y of the. casing and D1, the connection .vhich leads thence to the engine. n

E in' theend A2 of the casing is an air intake port in communication with the air intake passage E1.

The gate valves F, F1 which control the ports D and E are slidably mounted upon the opposed end Walls A1, A1, and are controlled by the the top A3. The screw-threaded lever F is provided at either end with the slot-SF5 to on the slide rodsF2, F3, and is mounted upon the collar kF"'vvhich is adjustably held by the nuts Fs and which is pivotalllv mounted upon the lug F9, which is adjustably held upon the top A3 by the screw F10 in the slot F11. The valves may be operated in any suitable manner from any suitwhich is pivotally mounted upon the collar G1 which, in turn, is adjustably mounted upon the rod Ft and held in position by the nuts G2.

lt will be evident that while I have shown in my drawings an yoperative device, still many Achanges might be made vin the size, shape and arrangement of parts without ldeparting materially from the spirit of my invention and I Wish, therefore, that my ings be. regarded as in a sense diagrammatic.

It will be understood, of course, that my invention is applicable to the use of any kind of hydrocarbon fuel such as oil, gasolene, alcohol and other similar fluids. y

The-use and operation of my device are as follows z-I provide a carburetingor mixing chamber with anair inlet and a mixture discharge communicating with the engine. The engine draws 4 its charge ,through the carbureting or mixing chamber and a vacuum is createdl yWithinv such 'chamber whichdraxv the hydrocarbon vacuum operates to and `water to forma combustible'niixture from the needle valve or other liquid supply. The amount 'of gas or. air passing out' of the carbureter tisvaried to control the speed of the engine land when this amount of air isvaried it will be obvious that the vacuum in the carbureting or mixing cham- `loerfmust also be varied in order to produce a combustible mixture. This variation produce by giving the valves controlling the air intake and mixture discharge ports. a relatively variable motion and this is done by mounting the gate valves upon either end of the rocking lever, the position of the fulorum of which may a different relative movement to each ofthe tWo valves for the same angular displacement of the lever. The connecting rod which actuates the lever is adjustablv mounted thereon and by an empirical adjustment of the position of the fulcrum and the position of the connecting rod it will be evident that some pointmay be found at which the controlling motion of the connecting rod will any position of the valves, bustion will then be found by starting at full load with the air intake and mixture discharge ports in the open position. The fulcrum of the lever F4 will be Aso placed that 'for any movement of the connecting rod G the movement of the valve F1 will be lessv than that of the rod F. The engine will then beslowed down until'a point is reached atwhich the mixture will be no longer satisfactory either because of too little or too much hydrocarbon', if because of too much hydrocarbon this will indicate too high a vacuum, and the fulcrum will be moved toward the right, giving a lessermovement of the valve. F1; if however l'iecause ot too little hydrocarbon this will indicate too litt-le a vacuum, and the fulcrum will be moved be adjusted, thus giving combustible mixture for.

and perfectcomtoward the left, givinga greater movement of the valve F1, the result being a greater.
