To rut 1m 011/ M 11.1 a conccm:

Be it known that I, ALBERT C. Fnnnrnn, a citizen of the United States, residing at Lincdln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Carbureter Attachments, of which the following is a specification.

This invention relates to a carbureter attachment for internal combustion engines useful for ponducting steam to the carbureter or intake manifold, from the radiator, to economize in the use of fuel and to prevent the formation of adhesions within the cylinders, and. also to reduce the temperature of the engine, and for one of its objects to provide means ."which are effective and con'venie for: superheating the steam. -Other objeets of the invention to means for a control of the movements of the superheated steam by an operator, so that it may enter the carl'mreter, the intake manifold or may be prevented fromentering either of them. The invention incllugdes means which, operate automatieaily' for permitting air from the at at to enter the carbureter upon certain dcasions when most needed, and also inclu es means for making certain adjustments found tobe of advantage, and to such simple structural parts that the device may be applied to engines readily at any time, or when constructed at the factory.

With the foregoing objects in view, the invention presents a novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in thmaccompanying drawing, it being understood that changes in form, size, proportion and minor details may be made within the scope of the claim.

the drawing, Figure 1 is a partly broken view in side elevation of an ntcrnal combustion engine in conventional 1 upon automobiles, showing the device iii-ed thereto. Fig. is a side view of a lve employed. 1s a sectional view 0 the valve housing. 4 is a transverse section on line "4: of Fig. 2. Fig. 5 is a. transverse section on line. 5-5 of Fig. 2.

Referring now to the drawing for a more particular description, i provide a conduct 'ing pipe 6 having one of its ends 02 disposed in the upper part of the radiator 7 above upper end of the combined vent and drain pipe 8, so that low pressure steam or moist air may be conducted .by the pipe, but that water will not enter therein, the opposite or lower end b of the pipe being at all times in communication with the intake port 9 of a casting or valve housing '10 for a conical valve 11 seated therein. said valve being under control for rotation in either direction by means of the inclined operating rod 12 secured thereto by a suitable key member 13, and pressed to its seat by the spring washer 14 under control of an adjusting screw 15.

Numerals 1G and 17 respectively indicate the carburetor and its fuel supply pipe. the conventional air intake chamber for the carburetor being indicated at 17. the supply of air generally being eon-trolled by a shutter, the lover of said shutter being indicated at 18. In the present instance this air intake is not employed and other means are provided for supplying air to the carburetor. At :1: is indicated a spring which is connected with the lever 18, and which operates in a manner to prevent. air from entering the carburetor in the usual way, by passing the shutter.

,The lower end of the valve housing is- 0 provided with a cylindrical compartment 19 in eou'unlmieation with the conical valve seat by means of a passageway 20 and in communication with the atmosphere by means of suitable intake ports 21 which are normally closed by a valve 22, the spiral spring 23 being pressed against this valve, and the tension of said valve being adapted to be,

adjusted by the screw plug 24 which circumscribes the valve stem 25. The valve 11 is provided, longitudinally, with a recess 26, and also is provided, to open upon recess 26, with a transverse recess 27. In order that the steam may attain a high degree of heat before entering the carbureter, suitable apertures are formed in the exhaust manifold 28, and the conducting pipe (3 may therefore traverse it for a considerable distance, as shown in the drawing.

An operator, by use of the shaft or red 12 may rotate the valve 11 so that the recesses 27 and 26 which define its passageway, will register with the ports 9 and 20 of the valve housing, the superheated steam thereupon passing through the nipple 29 and entering the compartment 17 from which it moves directly to the ,carhureter where it will become mixed with the-gas, and the mixture of. gas and heated steam will there-.

after-enter the intake manifold 30, with the result that the fuel will be economized. The steam thus introduced also tends to prevent carbon from adhering to' the inner walls of Since the pipe 6 which conducts steam to the carbureter will not supply a SllfilOlGIlt quantity of air at all times, the tension of the spring 23 is so adjusted that, by operation of suction, caused by the pistons in the engine cylinders, air from the atmosphere will enter the ports 21. It will become mixed with steam and will enter the carbureter ih a heated condition to supply all of the air needed.v

In some instances it is desirable to introduce su. erheated steam to the intake manito'prevent it from passing through and means are provided for The valve housing is proexjt port 31 and the intake this purpose. vided with an manifold is constantly in communication 'with said port 31 by means of the and it will be seen valve 11 substantially position of pipe 32, that, by rotating the a halfcircle from the .parts shown in Fig. 3, the port 20 will be closed and the steam ,will pass directly to the intake manifold, the valve 22 supplying air to the oarbureter. Also it will be understood that the three-way valve 11 may be rotated in a manner to close the I port 9 and thereby to prevent any steam from passing'said valve, this being desirable,

' when testing other parts of the engine, is

reouired.

second valve being provided with resilient Itfwill be understood that an operator, by use of the rod 12, may so dispose the valve llthatthe intake 9 will be entirely open .or partly closed, with the result that superheated steam may freely enter or that only ai'limited' amount of steam will be admitted to the; intake manifold or to the carbureter. Having fully described construction, a

further explanation relating to operation-is, I. .50

not necessary.

What I claim as my invention and desire to secure by Letters Patent'is,-

Devices for the purpose described, 'com prising, in combination with the intake manifold, the radiator, the exhaust manifold and the carbureter of an internal, combust'ion engine, a conducting pipe traversing a' part of the exhaust manifold and communicating with the radiator, a valvehousing provided with a compartment communieating with the carbureter and also provided with an air intake, a valve in the valve housing, said valve being movable to permit a communication between the conducting pipe and said compartment, a second valve, said means for normally causing a closure of said an intake and adapted to have a. movement to permit air to enter said compartment,

said first named valve being also movabllfm for terminating the communication of tlf to conducting pipe with said compartment and permitting a communication of the conducting pipe with said intake manifold. I
