FUELHEATER.

1.1 oaoesl To all c/110m it may concern Be it known that I, THOMAS TAYLOR, a citizen of the United States, residing at Kenton, in the county 'of Hardin and State of Ohio, have invented certain new and useful Improvements in Fuel-Heaters, ofwhich the following is a speciiication.

The present invention relates to an improved fuel heater to be used -in connection with and attached to an internal combustion or vapor engine.`

The primary object of the invention is the provision of means for heating kerosene and air as fuel for vapor explosive engines, and in order to accomplish this purpose economicallyand conveniently, I utilize the exhaust gases from the explosive engine as they pass through the heating device to bring the kerosene to almost the boiling point and' also to he'a't'the air to a very, high temperature and these conditions provide a more eiiicient mixture for fue than that obtained from gasolene. In cnnection with the attachment I utilize ajgasolene carbureter for the initial combustion in the engine, and after the engine is running, and the exhaust' therefrom has heated the kerosene so that it may be thoroughly volatilized, the gasolene is used exclusively.

In the accompanying drawings `I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have practical application of the principles of the invention.

Figure l is and an accompanying carbureter, the latter being shown as connected to an engine, and the former connected with the exhaust from the engine. Fig. 2 is a sectional view of the carbureter on line 2 2 of Fig. l. Fig. 3 is a transverse sectional'view showings. portion of the fuel heater and illustrating particularly the kerosene coil with its ends leading to the fuel tank and to the carbureter.

In the preferred embodiment of my invention I employ the two heads 1 and 2 between which are fixed the outer shell 3 and the inner .casing e', both cylindrical in form andv spaced apart to form a hot air chamber 5 which. is open to the atmosphere through the lower end of the shell. The heads ofthe heating drumare erfoto receive a pipe connected with the exhaust of the engine, and

the head 2 to receive a perforated tube 8 'whfich extends up -into' the interior of the cas-ing 4 and pointed end 9.l

has a closed pack the joints 'are used to receive and gases of combustion from the working engine. e Acoil otlpipe 1.1 is located within the inner casing 4.-, adjacent its wall, one end of which, 12, is connected with a kerosene sup?` ply tankv (not shown)` and the other end 13 is connected to a kerosene tank 14: forming part of4 a carbureter to be described. Sleeves or hollow bosses 15, integral With the casing 4; are located in which the pipe ends pass, and lock nuts-16, 1G, are employed to make a secure fastening of the pipes at the outside of the shellk 3. The carbureter 4illustrated in Fig. 2 is connected with th'e hot air space 5 through the opening in the shell and the short flanged' pipe 17, and the carbureter is secured to the heater drum and engine by means of the iianges 18 and -19 and suitable bolts. The carbureter 'cylinder 20 is open to the passage of heated air fromthe heater drum to the engine, but the trolled and regulated by means'of afturn` plug or valve 21 located in the open lower end of the cylinder and revoluble therein. This valve is formed with an annular groove 22, and by means of the bolts 23 in the wall of the cylinder which enter the groove, the plug is held against displacement and may be turned by the handle ,24. The valve is cylindrical in cross'sectin and is cut away or cupped at 25 to provide communication between the short pipe 17 and the interior of the cylinder 20. It will be understood that by revolving theirecessed plug the area of communication may be increased or decreased. The heated kerosene passes from the tank 26 and the fiow of sprayed li uid is controlled by the needle valve 2 which is threaded in the top or cover 28-of the cylinder, and an overiiow pipe 29is used to carry supply tank any excess of kerosene 1n the tank 14. A. second needle,

back tothe fuel valve 30 controls the supply of gasolene in the cylinder 20, from the gasolene tank 3l which is equipped' -'with the usualiioat 32 and valve 33 and inlet pipe. By extending. the tube or outlet receives a supply from the pipe 8 withits perforations entirely through the space 5, through 14 through the 'tube passage of the air is conthe coils and far into the hea-ting or exhaust chamber of the casing 4, the full heating properties of the gases of combustion as they are exhausted from the engine,

the heating coil as the gases How through lthe heating chamber and into 'the perforakerosene in` the coils to almost the boiling point. the valve 30 is closed, and the Valve 27 which has been iipreviously closed, is now opened, shutting o the gasolene supply and opening up the kerosene supply. The kerosene in the coils is heated by the gases as,

-they pass through the casing 4f and the perforated pipe 8, and the air for-fuel passing through the space 5 is heated also and passes through. the plug valve 21 to the cylinder 20. The vaporized kerosene in its heated condition, and the heated air are eommingled in the cylinder or carbureting chamber 2O and pass from there into the cylinders of the engine. By thus heating the kerosene, which normally is less volatile than gasolene, and heating the air, a mixture is produced which provides a more powerful eX- plosion than is obtained from gasolene, a comparatively tained, and the objectionable soot or smoke which is so injurious to the engine, spark lug, etc., is eliminated The attachment may be made to form a Copies of this patent may be obtained for five cents. each, by addressing the Washington, D. C.

ai'e felt upon perfect combustion is at-v part of an engine as-originally constructed, andit is equally applicable for use With existing engines ofA various types by modifying the size of theattacliment, and changing the design of the attaching flanges, etc.

Having thus fully described my invention, what I claimv is l. In a fluid fuel heater the combination of a perforated shell forming an air chamber, an imperforate casing Within the shell and a coil in the casing having inlet and outlet, an inlet pipe to the casing, and a perforated outlet pipe extending from one end of the casing to near the otherend thereof, whereby the coil is heated by gases flowing throug'lithe casing to the outlet pipe.

' 2. In a fluidfuel heater, the combination with a carbureting chamber and kerosene tank communicating therewith, of a per.- forated shell, an inipeiforate casing within thev shell, :an inlet for heated gasestosaid casing and an outlet pipe, perforated, and extending from one end of the casing to 'near the other, the space between the shell and casing forming an air chamber and communicating with .the carbureting chamber,

and a coil in the casing communicating with said tank, whereby the coil is heated by the gases flowingthrough the casing to'l the outlet pipe. h 4
