Be it known that I, CHARLES. Crmr- MAN, citizen of the United States, residing at Fort Edward, inthe county'of Washington and State of New York, have invent-,

ed certain new and useful Improvements in Methods and Apparatus for Burning Heavy with a generating chamber 3 which is coiextensive with the length of ,the exhaust- Oils in Hydrocarbon Engines, ofwhich' the following is a specification;

car on burners or *mternal combustion ene gines and has particular reference toasystem for supplying a 'carbureted mixture to internal combustion engines. ,1

This application is, a continuation in part,- of my 'copending ap lications, carbureter, Serial No. 368,192, ed March 23, 1920, superheater, Serial No. 368,191',"fi1ed March 23, 1920,'and superheater, Serial No. 420,481 filed October 29, 1920. I

In the present invention, one of the important features resides in the combination with the carbureter set forth in my application Ser. No. 368,192,'and the superheater set forth in my application Ser. No. 368,191, of means for separately ,superheating and finally mixing air and steam and supplying the saine to the carbureter while at the same time admitting, from the cooling system of the engine, a supply of water which is led to a steam generator from which the steam thus formed is fed to the said means.

Another feature of the present invention resides in the arrangement whereby all of the exhaust gases from the engine are utilized, thus avoiding wasteof thermal energy.

In the drawings:

Figure 1 is a side elevation of the system as applied to a motor vehicle, I

Figure 2 is a side elevation, partly in section, of the automatic water feeding means,

Figure 3 is a transverse sectional view through the combined superheater and mixer supplying the carbureter, and

igure 4 is a transverse sectional view through the superheater employed between the carbureter and the engine.

The invention is combined with the usual internal combustion engine A of the water jacketed type having the exhaust and intake manifolds 1 and 2 respectively, with which are connected the superheater B and carburetin system C described and claimed in the applications previously identified and which,- therefore,need not beset forthlin deta11 in the; present specification. How ever, it should be observed that the super-:

heater B constitutes a means for heating the carbureted zproduct delivered thereto from -the carbureter G. a

The exhaust pipe 1 has cast integral therepipe from the first to the last cylinder and-receives water from an admission pipe 4 which carries valves 5 and 6 placed in ahnement andpconnected byth'e, pipe 7 with s former-having a threaded stem as indicated at 12-, provided" with ahead 13 engaging.

with a fork 14; having a spindle 15 leading to the dash button adjustment as indicated at 16, while the spindle 17 of the needle valve 11' is connected at 18 with a diaphra m 19 carried in the housing 20 bolted toget er at 21 and connected by a nipple 22 and pipe 23 with the intake manifold 2, as shown; a spring 24 normally holding the valve 11 on its seat. Stuffing boxes 25 pack the respective valve stems so as to prevent leakage.

In operation, the needle valve 10 is ad-- justed to permit a constant flow of the reuire-d amount of water for maximum con itions and the needle valve 11 is adjusted by the suction on the diaphragm 19 so that the required amount is fed to the steam generator 3 dependent, on the suction in the inlet manifold 2.

The steam thus generated by contact with the exhaust pipe is then led to the superheater D by the pipe 26 while air is taken into' the supcrheater by the pipe 27 throu h the screened opening 28, the superheater being of the character shown in m pending application filed March 29, 1920, erial No. 420,481. A portion of the exhaust from the engine is taken off at 29 and fed through the superheater B, thence passing through the pipe 30 to the superheater D and final y erly proportioned for this purpose.

coil such as is described in my copending application, Ser. No.- 368,192, filed March 23, 1920, for a carburetor. The combined area of the exhaust outlets above referred to is the equivalent of the outlet area of the original exhaust passage and thus amply provides for taking care of all of the exhaust gases, the outlet holes 31 being prop- It will be seen from the foregoing description, that. the heavy hydrocarbons such as kerosene and the like, fed through the carbureting system C, receive a combined mix-- ture of steam and air from the superheater D, thus supplying the necessary oxygenand manifold and closed to the atmosphere, a

water inlet pipe connected to the chamber near its forward end, a steam outlet pipe connected to the chamber near its rear end,

a valve casing interposed in the .Water pipe,

a housing mounted on said chamber, a diaphragm in said housing, a valve connected to the diaphragm at one side thereof to extend into said casingfor controlling the flow I of water through the Water pipe, into said chamber, a 'suction'pipe for attachment to an engine intake manifold and connected to said housing at the opposite side of the diaphragm, and a second manually operated valve interpo-sedin said. Water pipe for controlling the flow of water to said first mentioned valve. I

2. The combination with an internal combustion engine, of a carbureter supplying carburetted gas to the engine, acombined superheater and mixer connected to the primary air intake of the carbureter for heatlng all of the primary air supply ofv the carbureter prior to the delivery of such supply to the carbureter and mixing said supply with steam,'a steam generator heated by the exhaust manifold of the engine and supplying the superh'eater with steam, and a superhcater connected with the outlet of the carbureter between thecarbureter and engine for heating carburetted product.

In testimony whereofI afiix my signature.

CHARLES CHAPMAN. [1,. 5.
