HYDROCARBON-IBURNER.

Specification of Letters Patent.

Application filed January 14,1911. Serial No. 602,730.

To all'whom it may concern:

. Be it known that we, ORLO F. SHEARMAN and CHARLES F. ERDMANN, citizens of the The object of the invention is to provide a hydrocarbon burner of this character in which the liquid fuel is mixed with air prior to its passage into the vaporizer.

A further object is the provision of means whereby air under pressure may be used for feeding the proper quantity of air to be mixed with the oil and also be used as a means for forcing the oil into the vaporizer.

A further object is to provide a vaporizer and burner of this character which may be readily cleaned by forcing the compressed air through the tubes of the vaporizer and out through the openings of the burner, thereby clearing the pipes and passages of the burner from soot or other accumulations of foreign 'particles.

A further object is to provide the combination with a vaporizing burner of a flame-. deflecting plate supported immediately over the vaporizer and burner, so arranged that it will deflect the flame from the burner outward and around the circumference of the plate, the deflecting plate being so formed that a section of it may be removed in order to permit the ,primary ignition of the gas.

A still further object'is the provision of a combined priming cup and burner located below the vaporizer and so arranged that the jets arising from the burner will play around the coils forming the vaporizer so as to obtain a maximum application of heat to the vaporizer.

Our invention is illustrated in the accompanying drawings wherein:

Referring to these figures, it will be seen Patented Feb. 13, 1912.

that the vaporizer 2 comprises a conical volute formed of a metal pipe or tube, the

apex of the volute being downward. The

extremity of the coil forming the vaporizer is-carried downward as at 3 and terminates in a burner 4, this burner preferably having the form of a cylindrical chamber provided upon its upper face and surrounding the pipe 3 with a plurality of jetopenings 5, Preferably formed integral with the burner or chamber 4 is the priming cup 6 which is, of course, larger in diameter than the burner 4 and is of sufficient depth to contain a properamount of fuel for priming. The upper end of the coil 2 forming the vaporizer extends outward at a tangent as at 7 and passes through the walls of the stove orfurnace A. The pipe 7 is connected to a T 8, one branch of which is connected to a fuel supply pipe 9, 'while the other arm of the directly opposite to the pipe 7 is connected to a pipe '10 which passes to an elbow 11 from which a pipe 12 extends to a compressed air tank 13. The T 8is provided with a valve 14 whereby the admission of fuel from the pipe 9 to the pipe 7 may be regulated. The elbow 11 is alsov provided with a needle valve 15 whereby the passage of air from the pipe 12 to the pipe 7 may be controlled. The supply pipe 9 extends into an oil tank or other suitable fuel reservoir 16. Preferably, the pipe 9 extends to the bottom of the tank 16 as illustrated in Fig. 1; The tank '16 is connected to the compressed air tank 13 by means of a pipe 17 which extends from the upper end of the tank 16 and is provided with a valve 18 13 and 16 may be established or cut off. The tank is further provided with a filling opening 19. The compressed air tank 13 is connected, preferably at itsupper end, by means of a pipe 20 to any suitable air compressor, as for instance an-air pum not shown, and the pipe 20 is provided with a whereby communication between the tanks valve 21 whereby communication may be established between or cut -off between the air pump and the compressed air tank 13.

v about an inch space is left between the pcriphery of the deflecting plate 23 and the walls of the stove orfurnace. Eccentrically disposed in theplate 23 is an opening 24 normally closed by a lid or removable section 25, the margin of the plate 23 immediately around the opening 24 being deflected to form an annular flange upon which the lid 25 is supported. The lid 25, is provided with a recess 26 whereb an implement may be applied to raise t e lid. The

deflectin plate 23 is supported in any suitg of heat and for an increase in the heating able manner but preferably by means of supporting bolts or studs 27 extending upward from the uppermost eoil of the vaorizer 2. Nuts on these bolts hold the deecting plate in position but permit thef deflecting plate to be easilywemoved when' desired. In order to hold the deflecting; plate, the vaporizer and the burner in proper relative position within the stove or furnace, we preferably provide one or more hookshaped bolts 28 which pass through the walls of the furnace or heaterand'have upwardly extending terminal portions which: pass up through openings formed in fhe margin of the deflecting plate. These bolts 28 hold the deflecting plate in proper position so as to leave a space between the pe-'; riphery of the deflecting plate and the wali' of the stove or heater.

In practice, when it is desired to start our improved burner, the valves 14 and 15 are closed and the valves 18 and 21 opened: and the air in the compressed air tank13 and supply tank 16 compressed to any dew sired degree. After the desired pressure has been secured in the tanks, the valve 21 is closed. It will now be seen that there is pressure of air upon the upper surface of the oil contained within the tank 16. The

valve 14 is now opened and oil passes from the tank 16 through the pipe 9, the T 8 to 55 The liquid fuel passes down these coils of pipe and is forced out through the openings the coils of pipe forming the vaporizer.

5 in the chamber or burner 4. This. oil

so forced out accumulates in the priming cup 6. When the priming, cup is nearly full of oil, the valve 14 is'closed and the oil in the a cup 6 is lighted. When the oil is nearly burned out of the priming cup, the valve 14 is opened a slight amount and when the oil igmtes from the flames in the priming' cup then'the'valve 15 is o ened a slight amount. Gas is then forme izer 2 and escaping through the opening 6 is ignited and burns with a blueflame which is entirely smokeless and odorless.

When it is desired to ignite the oil in the priming cup, it is only necessany to remove the section 25 of the deflecting plate. A match may then be easily applied to the oil in the riming cup. The deflecting plate causes t e flames to pass up adjacent to the wall of the stove, furnace or other heater and thus provides for a better distribution power of the .stove or furnace. It will be seen that ,the flames proceeding fromthe orifices 6 willlay over, around and between the pipe ormingthe vaporizing coil 2 so that a particularly effective application of heat occurs for the proper vaporization of the fuel before it passes to the burning orifices. It is further to be noted that air is admixed with the fuel prior to its passage eat is produced. I

gas than where the air mixes with the fuel after the latter is vaporized. Further, it .is

to be noted that the air is forced into the 4 T 8 under pressureand tends to nebulize the oil as it passes into the vaporizer.

It will be observed that the vaporizer being in the form of an inverted conlcal volute, tends to deflect the flames arising from the burner 5 upward and outward to the circumference of the deflecting plate 23 and between the periphery of the deflecting plate and the walls of the heater A. At the same time some of the flames will play upward within the space inclosed by the tubular vaporizer and between the coils of the vaporizer so that the vaporizer will be thoroughly heated. It is further to be noted that when the air pressure has been entirely exhausted within the tank 13 the oil will no longer be forced into the burner and hence that the fire will go out.

By connecting the compressed air'tank '13, both with the 011 tank 16 and with the T 8,- we secure a positive feed of oil to the burner and also secure a positive feed of air thereto.- The amount of compressed air'within the tank 13 may be easily adjusted so as to cause the burner to operate for any desired length. oftime. By closing pfl the connec- 7a The burner as described will work to ex- While we haveshown what we believe tobe the best form of our device, and a form which we have found to be extremely eflective in practice, we do not wish to be limited thereto as it is obvious that many minor changes might .be made therein without departing from the spirit of the invention.
