CARBURETOR.

GPEC'IFICATION forming part of Letters Patent No. 303,927, dated August 19, 1884.

Application filed January 16, i884. (No model.) I

To (455 whom. it M21111] concern:

Be it known that I, GEORGE FRoH, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful lmprovement in Carburetors, which improvement is fully set forth in the following specification and accompanying drawings,in which- Figures 1 and 2 are vertical sections atright angles to each other ofa carburetor embodying my invention. Fig. 3 is a horizontal section on a reduced scale in line a: m, Fig. 2.

Similar letters of 'reference indicate corresponding parts in the several figures.-

My invention consists of a carburetor in which the flow of the carbui'eting-fluid is automatically and nicely controlled in two chamhers, and other details of construction are presented, as will be hereinafter fully set forth.

Referring to the drawings, A represents a casing made of any suitable material, preferably metal, the same being divided into a receiving-chamber, B, a chamber, 0, communicating therewith, with a perforated or gauze partition, 0, between them, a floatand valve chamber, D, another float-chamber, E, a carbureting-chamber, F, and a drip-receptacle,G.

Secured to the bottom of the chamber 0 is a hollow valve-seat, H, the same having openings or ducts a, which open into said chamber 0, the bottom of said seat opening into the chamber D, thus forming a communication between the chambers C D.

J represents a valve, which opens downwardly from said seat H, and is secured to the stem J, which is properly guided in the scat H and the bottom of the chamber D.

Loosely encircling the stem J, below the valve J in the chamber D, is a sleeve,K,which is attached by means of a bar, K, to floats L in the same chamber D; and firmly secured to said stem J, between the valve J and sleeve K, is a stop and deflector, M.

Communicating with the chambers D and F is a pipe, N, which in the chamber F is formed with perforated branches N", from which are suspended strips or pieces P of ab sorbent material, the same being adapted to be saturated by hydrocarbon fluid which escapes through the perforations of the branches N.

At the bottom of the stem J is a float, Q,

position within the chamair-discharge pipe leading from said chamber,

it being noticed that said chamber is threesided and thereby enlarged.

T represents a pipe communicating with the chamber G for discharging the drip and accumulations of said chamber.

The operation is as follows Gasoline or other hydrocarbon fluid is admitted into the chamber B through the supply-pipe U, and the displaced air escapes through the pipe V. The fluid enters the chamber 0, and flows into the valveseat through the ducts a, and enters the chamber 1), whence it is directed by the pipe N and branches N into the carburetingchamber F, saturating the material P, as has been stated. Air is forced through the pipe B into the chamber F and passing through the same, and the saturated material 1? becomes charged with hydrocarbon and carburetcd, in which condition it is discharged through the pipe S and directed to the place of service. Should the fluid flow too freely from the chamber (J and collect to an undesirable extent in the chamber D, the floats L rise and cause the sleeve K to strike the stop M, whereby the valve J is raised and accordingly closed. Vhen the supply of fluid is equalized or adjusted, the floats fall and permit the valve to reopen. Should there be a collection of fluid in the chamber F, it may escape therefrom through an'opening, W, in the inner vertical wall of the chamber E into said chamber E, and cause the float Q to rise and close the valve until said collection is dis posed of either by evaporation or escape into the chamber G through an opening, X, at the bottom of the chamber E, said opening also permitting water, condensed matters, and drip generally to enter the chamber G, from which the same may be pumped or otherwise re moved by the pipe T, as has been hereinbe fore referred to.

In order to cause the floats L Q to move steadilyandwithfacility,thesameareprovided with rollers, which are properly guided within the chambers containing said floats.

Y represents wood or other proper material with which the casing Ais lined, thus protecting the interior of the carburetor from the influences of changes of temperature and other injurious effects.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A carburetor having a valve, a float in the chamber leading to the carbureting-chambar, and a float in the chamber leading from said chamber, both floats closing said valve when there is an excess of carbureting-fluid. in either chamber, substantially as and for the purpose set forth.

2. The floats L Q in different carburetingchambers, in combination with the valve J,the
