lThe invention relates to carbureters fork internal combustion engines and particularly for internal combustion enginesernploying the 'heavier hydrocarbon fuels.
An object of the invention is to provide a carbureter in which there are positive connections between the throttle valve and the auxiliary air inlet `valve, so that the tu-'o are simultaneously actuated.
Another object of the invention is to pros ride a carbureter in which all the incomingr air is directed against a hot Wall of the carbureting chamber, and by the design of the carburetor to provide means whereby the hot gases from the engine may be passed about the Walls of said chamber.
Another object of the invention is to proride a carbureter in which the velocity of the mixture being drawn from the carbureting; chamber is utilized without the inter- Yention of moving parts to vary the pressure within the oat chamber, so that. the volume of fuel being discharged from the nozzle is varied in proportion tothe speed of the engine.
Another object of the invention is to provide a carbureter capable of elliciently vaporizing kerosene, distillate or other heavy hydrocarbon fuels.
The invention possesses other adr-autageous features, which.` with the foregoing. Will be set forth at length in the following description. where shall fully explain that preferred form of my intention which is illustrated in the drawings accompanying and forming part of the specification. The novelty of the invention 'will be included in the claims succeeding1 said description. From this it is apparent that l do not, limit myself to the showing made by the said drawings and description` as l may adopt many variations Within the scopel ot my inifenton as set forth in the said claims.

ig. 2 is a Vertical sectional View through the carburet-er of my invention. v
The carbureter of my inrention comprises a carbureting chamber 2, arranged so that hot exhaust gases from the engine entering through the conduit and emerging through the conduit 35 may circulate about in the rchamber .4 and heat the bottom and side Walls 5 and 6 of the carbureting chamber.
Y Beneath the wall 7 which is also heated by the hot gases is a horizontal passage 8 comrminicatinf; at one end with the spray nozzle 9 and at the other end with the fuel or float chamber 12. The temperature of fuel passing from the fuel chamber is thus raised be-` fore it reaches the nozzle and the subsequent spraying and raporization of the fuel is promoted. This is of particular value Where heavy hydrocarbon fuels are used.,
ln the fuel chamber 12. a float 13 actua-ting the valre 1l controls the admission of fuel into the fuel chamber from the supply pipe 34, a risinT ot the lioat shutting the relre and a loitering of the float opening it.
Leading into the carbureting chamber from theair inlet 15 is a liv-pass 16 terminating in a. tube 17 which incloses the upper end of the spray nozzle 9. rl`his passage is always open and conducts the air past the downwardly directed discharge apertures 18 of the nozzle, dgau'ing the fuel therefrom in a spray and iihpinging the mixture downwardly against the heated bottom Wall of the chamber Q. The inlet irfor the auxiliary air is controlled by the *valve 19. The inner end or" the inlet passage is curved downwardly, at 21, and surrounds the tube 17, so that the air entering through.'
the passage Qi is thoroughly mingled with the fuel mixture issuing from the tube 17 and is also directed upon the hot Walls of the carburetinpT chamber. The fuel mirturel isdrawu out, et the carbureting chamber through the outlet passage 22 which is controlled by the throttle valve 23. Positive mechanical connections are provided between the auxiliary air inlet valve 19 and the Revers Q4 and 25 are se-A cured to the stems or the throttle and air valves respectively and are connected by the link Q6 which is Amede adjustable in the slotted portion of the air Valve lever 25 by the thumb nut 9,7 so that the valves may be adjusted to suit the conditions, "When the
