UNITED! STATES PATENT OFFICE,

WILLIAM a. LITTLE, on THE PRIORY, GONISBORO, COUNTY oEYonK, ENGLAND.

BURETOR.

SPECIFICATION forming part of Letters Patent No. 322,116, dated July 14, 1885. -Applicntion filed May 152 1885. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM GODSON Lrr- TLE, residing at The Priory, Conisboro, Yprkshire, England, British subject, have invented a certain new and useful GasOarburetor,for increasing the illuminating power of ordinary coal-gas by means, of a solid hydrocarbon candle inserted into a carburetor, constructed as hereinafter shown, and of which the following is a specification.

The object of my invention is to evaporate a thin film of melted hydrocarbon 1natter,"(by preference, naphthaline obtained from the distillation of coal-tar,) to mix the vapor therefrom with coal-gas, to maintain the said film at a constant level, and to burn the vapor of hydrocarbon and the coal-gas at the same burner or burners which cause the melting and evaporation of the hydrocarbon. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a gas-pendant suspended from the pipe A, joining a three-way cock, B, having three outlets, A C D. By'turning the cock B, I can direct the current of gas either down the pipe 0 or down the pipe D. If I direct the gas down 0, it will take the course indicated by the arrows, finally issuing at the burners below.

E, the carburetor, is a circular domeshaped vessel with a fiat bottom. To the top of this vessel is attached a brass socket, G, turned accurately on the inside, and into which fits a brass conical plug, H. Through the plug H passes a tube, F, closed at the top end, and which is soldered or brazed into it and passes downward into the vessel E. When the plug H is pressed home into the socket G, the bottom of the tube F should be within about one-eighth of an inch from the bottom of the vessel E.

J is a stop in the pipe 0.

K is a 'circular disk of copper' or brass, which can be raised or lowered by screwing it on the threads Lon the pipe D Fig. 2 is the plug of the cock B, which is an ordinary gas-cock plug cut through on one side, as shown. It will be seen that this form of plug will admit of the gas being directed down the pipe 0, or down D, or down 0 and D together; or the gas may be shut off altogether by turning the solid side upward.

To work the apparatus, the tube F is withdrawn and a solid candle of naphthaline iutroduced into it. It is then replaced into the socket, and the naphthaline will rest on the bottom of the vessel E. The cock B is then opened, allowing the gas to flow down 0, and it is lighted. The heat from the burners, which may vary in number from one to a dozen, will then Warm the bottom of the vessel E, causing the naphthaliue to melt and flow over it, and the film will rise until it seals the bottom of the tube F, when no more can flow out. \Vhen the temperature is sufficiently high the film will commence to evaporate, and the vapor will be carried along with the gas which fills the vessel E to the burners. Should the heat from the burners be too great and cause too rapid evaporation, it can be regulated by screwing down the plate K, and if it is necessary to prevent the flames from smoking meanwhile, the cock B can be turned so that any desired quantity of gas can be directed down the pipe D without passing through the carburetor. When sufficient of the film is evaporated to unseal the bottom of the pipe F, more of the hydrocarbon will flow out until it is again sealed, as before, gas taking the place of the hydrocarbon.

The bottom of the vessel E is pierced by the pipes O and D, as shown.

I am aware that prior to my invention carburetors have been made for mixing hydrocarbon matter with coal-gas.. I therefore do not claim such a combination, broadly; but

What I do claim as my invention, and desire to secure by Letters Patent, is- V 1. The combination, in a carburetor, E, of go a tube, F, closed at the top, inclosing a solid hydrocarbon candle and held firmly by a conical plug, II, and brass socket G, about one-' I eighth of an inch above the bottom of vessel E, all substantially as set forth.

2. The combination, in a carbureting apparatus, of the vessel E, pierced with pipes C and D above the level of the bottom of the vessel, with the tube F, fastened above and line has evaporated to nnseal the bottom of tube]? more melted naphthaline is allowed to 10 run out until the bottom of tube F is again sealed, as before.

near the bottom of E, containing a solid candle of hydrocarbon resting by gravity upon the bottom of the vessel E, whereby the naphthaline is allowed to melt by the heat from the gas-burners and spread over the bottom of the Vitnesses:
