CARBURETER.
Specification of Letters Patent. Patented Dec. 14, 1920.
Application filed June 13, 1917. Serial No. 174,498.
To all whom it may concern Be it known that we, ALVIN A, HANsnN and EARL M. STUKAS, citizens of the United States, and residents of Clinton, in the county of Clinton and State of Iowa, have invented a new and Improved Carburetor, of which the following is a full, clear, and exact description.
This invention relates to carbureters, and deals more particularly with mechanical means for causing the fuel to be effectively broken up into a mist for eflicient carburization.
The invention has for its general objects to provide in the mixing chamber of a carbureter, a simple, novel and effective device which causes the liquid fuel to be sprayed into the chamber and to be further acted upon centrifugally for producing an extremely fine mist so that a better fuel mixture can be obtained.
A more specific object of the invention is the provision of a multiple spray device for the liquid fuel, combination with a rotary element driven at a high speed for causing the sprays to be broken up into fine particles or mists, the spraying device being of such a nature that the suction produced by the engine through the carbureter draws the fuel into the mixing chamber.
Another object of the invention is to provide an easy and effective control for the mixture by means of a valve used in combination with the spray device, whereby the number of spraying apertures may be opened or closed, as conditions require.
With such objects in View, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.
In the accompanying drawing, which illustrates one embodiment of the invention and wherein similar characters of reference inclicate corresponding parts in all the views,
Figure 1 is a central vertical section;
Fig. 2 is a horizontal section on the line 22, Fig. 1; and
Fig. 3 is a perspective view of the valve for controlling the number of operative spray apertures.
Referring to the drawing, A designates the body of the carbureter, which may be which is carried by its bottom being screwed or otherwise fastened in the hub 5 of a spider cast in the bottom of the body section of the carbureter. Qne arm of the spider is formed with a passage 6 through which fuel is supplied from a float chamber or other source through a pipe 7. The upper end of the tube a is closed, and at one side the tube has a line of apertures 8 through which fuel is sprayed under the suction caused by the operation of the engine. Mounted in the fuel tube is a rotary valve 9 which is hollow and has a port 10 which registers with the passage 6 so that fuel can enter the valve. The valve is provided with an upwardly flaring slot formed with a straight longitudinal edge 11 and a helical edge 12. By turning this valve the helical edge will cover or uncover the apertures 8 to thereby vary the number of jets of fuel, and hence the volume that is drawn into the mixing chamber by the suction of the engine. The valve 9 has a stem 13 which projects downwardly through a stuffing box 14 carried on the lower end of the fuel tube 4, the bottom of the stem extending at 15 out of the bottom of the carbureter and being connected with suitable mechanism controlled by the operator for varying the fuel mixture. In the mixture outlet 2 is a throttle valve 16 whereby the suction through the carbureter, and hence through the volume of mixture supplied to the engine, may be varied.
To insure an effective breaking up of the liquid fuel discharged through the jet apertures 8, a rotary device B is mounted in the mixing chamber. This device comprises a plurality of dished rings, disks or the like 17 arranged in superimposed relation and spaced apart, so that at least one jet aperture 8 will lie between two adjacent rings. These rings are carried by arms 18 ona rotatable shaft 19 which is mounted on a ball step bearing 20 carried by the fuel tube or an equivalent part, the upper end of the shaft 19 being extended out of the carbureter and being connected with suitable mechanism for driving the mist-producing device B at a very high speed. The fuel delivered from the orifices 8 strikes the rings 17 and is thrown outwardly thereby by centrifugal force across the up-flowing stream of air, whereby an efficient commingling of the air and fuel is produced.
From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled and the art to which the invention appertains, and while we have described the principle of operation, together with the device which we now consider to be the best embodiment thereof, we desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.
Having thus described our invention, we claim as new and desire to secure by Letters Patent:
1. A carbureter comprising a body which includes a mixing chamber with an inlet for air, an outlet for fuel mixture, a longitudinally extending fuel tube in the chamber and having a plurality of jet apertures in its side, a valve disposed in the tube and movable to cover or uncover the jet apertures successively to vary the proportion of the fuel and air, and a plurality of spaced rings mounted to rotate around the apertured portion of the said fuel tube for breaking up the fuel jets from the apertures into mist.
2. A carbureter comprising a body which includes a mixing chamber with an inlet for air, an outlet for fuel mixture, a longitudinally extending fuel tube in the chamber and having a plurality of jet apertures in its side, a valve disposed in the tube and movable to cover or uncover the jet aperbreaking up the fuel jets from the apertures into mist, said device comprising a plurality of rings spaced apart so that an aperture of the tube will be between two adjacent rings.
3. A carbureter including a body having a fuel chamber provided with an air inlet and a fuel mixture outlet, a throttle in the said outlet, a fuel-tube extending longitudinally of the said chamber, means for supplying fuel to the tube, said tube having a plurality of laterally discharging jet apertures, a valve controlling the said apertures, a plurality of dished rings surrounding the apertured portion of the tube and having their outer edges slightly spaced from the walls of the mixing chamber, said rings being spaced apart so that an aperture of the fuel tube will be between two adjacent rings, and mechanically driven means rotatably supporting the said rings, whereby the liquid fuel on the said rings is thrown outwardly into the air flowing through the space between the edges of the rings and the walls of the mixing chamber.
4. In a carbureter, a body having a mixing chamber provided with an air inlet and an outlet for fuel mixture, a longitudinal fuel tube in the mixing chamber and having a plurality of jet apertures, a valve in the tube for controlling the apertures thereof, a shaft extending into the mixing chamber and having a bearing on the fuel tube and provided with a plurality of arms, and a plurality of rings secured to the arms and SHII'OUIldiIlg; the fuel tube with an opening of the tube between two ad'acent rin s.
