CARBURETER.

APPLICATION FILED 1uLY2. 1913.

Patented Nov. 16, 1915.

vvbtmeooeo TIMON Jl'. BURNH, 01E JACKSON, M ISSI I SSTPJE'I.

cannnnnrnnr To all whom it may concern:

Be it known that I, TIMON J. BURNHAM, a citizen of the United States, residing at Jackson, in the county of Hinds and State of Mississippi, have invented new and useful Improvements in Carbureters, of which the following is a specification.

Thisinvention relates to a vaporizer for use in connection with internal combustion motors, the object in view being to produce a carbureter which is especially adapted for the use of kerosene and other hydrocarbon oils which do not vaporize as readily at ordinary temperature as gasolene, the carbureter of this invention being adapted to thoroughly vaporize the cruder forms of hydrocarbons preparatory to the introduction of. the same to the combustion chamber of an engine. 7

While the carbureter hereinabove described is particularly adapted for the purpose stated, it may also be used in connection with gasolene and other volatile hydrocarbons, serving to heat and deliver the same in better condition for combustion 'and expansion before reaching the engine. v

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will hereinafter be more fully described, illustrated and claimed.

In the accompanying drawings :Figure 1 is a sectional view of the carbureter, showing also an 'oil supply tank, feedpipe and battery. Fig. 2 is a cross section through the carbureter on the line 22 of Fig. 1.

Referring to the drawings 3 designates the carbureting chamber and 4 a fuel supply or feed pipe in communication with said chamber and with any suitable fuel supply tank or reservoir.

In the lower portion of the carbureting chamber 3 is arranged an annular distributing pipe 16 having any desired number of inwardly extending nozzles 17 which discharge the fuel oil against the top wall 18 of a heater, said top wall being preferably quite thin and dished as shown in Fig. 1. The main body 19 of the heater is exteriorly threaded as shown at 20 and screwed into an internally threaded neck 21 and the bottom of the carbureting chamber 3 so that said heater may be removed whenever necessary.

The formation of the heater as shown in Fig. 1 provides a heating chamber 22 in which is arranged an electric reslstance coll Specification of Letters Patent. V Pam gntgngdl New, 1165}, jllfimfi, Application filed July 2, 1913. Serial No. 777,057. I I

23 fromwhich the wires 24 and 25 lead to a battery 26 or other source of electrical energy. The coil 23 heats the top wall18 and thereby thoroughly vaporizes the gasolene as thev gasolene or other oil is received in' the mixing chamber and caused toimpinge directly against said wall 18.

27 designates the air pipe which extends centrally through the body 19 of the heater into which it is threaded as shown at 28, said air tube passing'through the heating chamber 22 and opening directly into the carbureting chamber 3, below the level of the noz- .shown in Fig. 1. Extending downwardly from the spreader 32 is a supporting and adjusting stem 33 which is threaded through the air pipe 27 as shown at' 3 1. The stem 33 projects outside of the pipe 27 where it is provided with a suitable adjusting head 35. This enables the spreader 32 to be adjusted nearer to or farther from. the air inlet where the air enters the chamber 3 and thus provides for spreading the inrushmg air causing the latter ,to take up the vapor andcarry the same upward through the discharge neck 36 of the carbureter, said neck being provided with the attaching flange '37 for connecting thecarbureter as a' I whole to a corresponding! flange on the intake pipe of an internal combustion motor (not shown). I

38 designates the usual butter-fly throttle valve which controls the discharge neck of the carbureter and the intake pipe of theengine in connection with which the carbu reter is used. I

In view ofthe foregoing description it will be understood that the heater may be thrown into and out of operation as may be desired in accordance with weather conditions and also in accordance with the character of the fuel oil used in the carbureter.

The fuel oil entering the carbureter is in the form of'a number of jets which impinge di rectly against the top wall of the heater whereby the oil is quickly heated and vaporized after which it is carried upward by the ascending column of air passing in through of the mixing chamber by the nozzles 17.

What I claim is i p 1. A carburetor for the purpose specified comprising a carbureting chamber having an air inlet, a heater arranged within the same,

an annular conduit encirclingv the space above sa1d heater, a clrcular series of 1nwardly pointlngnozzles connected with sald annular conduit, and a fuel oil feed pipe 1 leading to said annular conduit.

2. A carbureter for the purpose specified comprising a carbureting chamber, a heater v arranged within the same, an annular con- "zles connected with said annular conduit, a

fuel oil feed pipe leading to said annular conduit, a central air inlet in the bottom of the carbureting chamber, and a spreader arranged centrally of the air inlet and adjustable toward and away from said air inlet.

y In testimony whereof I afiix my signature in presence of two witnesses.

TIMON J. BURNHAM.
