CARBURETER.

Specification of Letters Patent.

Patented Aland, 1916.

Application filed. December 14, 1914. Serial No. 877,054.

To all whom it may concern:

Be it known that 1, JOHN BRIGKEN, subject of Russia, residing at Chicago, in the county of Cook. and State of Illinois, have invented a certain new and useful Improve ment in Carbureters, of which the following 'is a full, clear, concise, and exact description.

My invention relates to a carbureter for internal combustion engines and its ob ect 1s to provide simple and efficient means by which a liquid-fuel is converted into vapor and mixed with air to form the enginecharge.

A further object is to provide in a carbureter automatically operating means by which the desired proportion of air and gaseous fuel are automaticallymaintained, the amount of fuel supplied being automatically regulated by the flow of an through the carbureting chamber.

With the above objects in view, my 1nvention provides means whereby the liqu d is fed upon a revolving plate, the liquid tending to be held; upon said plate by adhesion and being thrown therefrom by centrifugal force.

My invention and the several features 6 thereof may be more readily understood by reference to the accompanying drawings, in

which- Figure l-is a longitudinal, central sectlon of a carbureter embodying my invention;

Fig. 2 is a transverse section on the line 2-2 of Fig. 1; and Fig. 3 is an enlarged, detailed plan view of the lower end of a spacing tube which communicates with the feed tube.

Like numerals of reference refer to like parts throughout the several views.

Referring to the drawings, the air supply chamber 1 of the carbureter is supplied with gasolene or other suitable liquid fuel from the tank or fuel supply chamber 2, said revolve by a series of vanes or blades 8, said vanes being preferably secured to and projecting from the disk 6, as shown in the drawlngs. The air suction through the chamber 1 causes the vanes 8 to rotate,'thus lmparting a-rotary motion to the disk 6. The speed of rotation of said disk is thus dependent upon the current of air flowing through the chamber 1. Such fiow of air may be controlled in the usual well known manner.

I preferably provide, immediately above the disk 6 and suitably spaced therefrom, a member 9 having at its lower end a circular, plane surface which extends parallel to the upper surface of the disk 6. The opposing surfaces of the disk 6 and the member 9 thus provide, as it were, a nozzle having a contracted, circular passage, the oil tending to adhere to the two opposing surfaces. The member 9 forms'the hub portion of an annular ring 10, which ring is threaded upon the interior of the casing of the chamber 1, whereby the member 9 may be vertically adjusted to properly space apart the disk 6 and the member 9. Threaded through the mem- 6. The tube 11 projects below the end of the member 9 andserves as a spacing block for separating the disk 6 from the member 9, thereby preventing the disk 6 from rising under the action of the revolving blade 8. At its lower end the tube 11 is provided with one or more grooves or notches 12, through which the liquid fuel may escape into the space between the disk 6 and the opposing surface of the member 9. Extending through the tube 11 is the stem 13 of a needle-valve of the usual construction, which valve can be adjusted to control the flow of the liquid from the feed 'tube 4.

The fuel tank 2 may be provided with the usual float 14: which controls, in a well known manner, the valve 15, thereby maintaining a predetermined fluid level in the tank 2. The level of the fluid in the tank 2 is preferably maintained slightly lower th an the upper surface of the disk 6, in order that when the engine is not running the oil will not flow from the pipe 4: onto the surface of the disk 6. Upon. a rotary motion being imparted to the disk 6, the centrifugal force exerted upon the liquid in the cavity thrown out, by centrifugal force, in the form of a fine spray or vapor, which becomes thoroughly mingled with the air passing through the carbureter l. The amount of liquid fuel discharged into the chamber 1 is thus dependent on centrifugal force,

which in turn is proportional to the speed of rotation of the disk 6, which in turn is proportional to the amount ofair passing through the carbureter chamber. The proportion of fuel to air in the engine charge is thus automatically maintained constant.

It is obvious that changes in the details of structure shown and described may be made without departing from the scope of the invention as defined in the accompanying claims.

So far as I am aware, I am the first to provide means by which centrifugal force is utilized for discharging liquid fuel in the form of a spray into the carbureting chamber of an internal combustion engine.

What I claim is 1. In a carbureter, the combination ofan air chamber, a rotatable member, an opposed member having adjacent parallel surfaces and means for separating said members to provide a nozzle opening outwardly in all directions without obstruction.

2.-In a carbureter, the combination of an air chamber, a rotatable plate,having a central opening, a hollow supporting shaft therefor, a feed tube, said shaft and feed tube being concentrically mounted and means mounted on said shaft for rotating said plate.

3. In a carbureter, the combination with an air chamber; of a fuel-discharge nozzle disposed within said chamber, said nozzle comprising two members having adjacent parallel surfaces, said members being relatively rotatable and one of them being provided with vanes adapted to be actuated by the air which passes through said chamber.

4. In a carbureter, the combination with an air chamber; of a fuel-discharge nozzle disposed wholly within said chamber, said nozzle comprising a revoluble member and an opposed stationary member; and means, actuated by the air passing through said fihamber, for rotating said revoluble mem- 5. In a carbureter, the combination with an air chamber; of a fuel-discharge nozzle disposed within said chamber, said nozzle comprising a revoluble member'and a member spaced therefrom to provide a clearance;

6. In a carbureter, the combination with an air chamber; of a fuel-discharge nozzle disposed within said chamber, said nozzle comprising a revoluble plate and an opposed member; and vanes carried by said revoluble plate.

- 7. In a carbureter, the combination of an air chamber, a vertically disposed fuel-supply tube located centrally of said chamber, a rotatable member mounted about the open end of said tube, vanes carried by said rotatable member, and a stationary member opposed to said rotatable member, said two members constituting a fuel-discharge nozzle.
