Application led June 29, 1927. Serial No. 20-2,304.

My invention relates to improvements in oil burners, and it consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide an oil burner in which the same air is utilized for placing the fuel under pressure and also for mixing with the fuel to form a combustible mixture.

A further object of my invention is to provide a device of the type described, in which the air and the fuel are mixed together at the tip of the burner, the pressure of the air and the fuel being dependent upon each other so that a regulation of the flow of air will automatically regulate the flow of fuel, thereby forming a perfect mixture, whether a low flame is employed or a high flame.

Other objects and advantages will appear in the following specification, and the novel features of my invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawing, forming a part of this ap- Figure 1 is a vertical section through a storage tank showing the burner operatively connected thereto; and

Figure 2 is a longitudinal section through the burner, portions thereof being shown in elevation.

In carrying out my invention I provide a storage tank 1, which has a filler cap 2:, an air compressor 3, and an automatic exhaust valve 4. Oil is poured through the opening 5 andthis oil is placed under pressure by means of the compressor 3. An `oil pipe 6 and an air pipe 7 lead from the bottom and top of the tank, respectively, and are connected to a burner indicated generally at 8. Valves 9 and 10 control the flow of fuel and air into the burner 8. It will be noted from Figure 1 that a drain plug 11 is mounted in the pipe 6 for drainingthe content-s from the tank l, when the operator so desires.

In Figure 2 it will be noted that the fuel pipe 6 communicates with an inner pipe 12 of the burner 8 and that this pipe terminates a short distance from the nozzle 13. A second pipe 14 encloses the pipe l2and is in communication with the air pipe 7. A nozzle 13 forms a mixing chamber 15 and from this chamber the mixture is forced through openings 16, and then through a small opening 17. These series of openings eifectually break up the fuel into minute particles and thoroughly mix the particles with the air, so as to form a combustible mixture.

From the foregoing description of the various parts of the device, the operation thereof may readily be understood.

I have found from experience that a burner constructed along the lines set forth is adapted to burn fuel far more readily than can be accomplished with other burners. AThis is due to the fact that the fuel is under the saine pressure as the air and that these two elements unite at the top of the burner and then are forced through a pair of small openings 16, and then through a smaller single opening 17. The pressure behind the air and the fuel causes a thorough mixture of the two prior to their issuance from the mouth of the burner. I have diagrammatically shown the burner as being disposed in an oven 18, or other device, to be heated.

The pressure is maintained by means of the compressor 3 and this pressure is strong enough to break up the fuel into minute particles, so that the burner can be ignited when cold. A change in the volume of the air by means of regulating the valve 10 will automatically adjust the amount of fuel'lowing into the burner, so that the required amount l will be conveyed to the fuel to form a perfect combustible mixture. In this way the device is more or less automatic in operation.

lAlthough I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes and I reserve the right to employ such changes as may come within the scope of the appended claim.

I claim:

An oil burner having an oil passageway therein and an air passageway surrounding the oil passageway, the walls of said air passageway extending beyond the end of the oil pasageway for forming a mixing chamber having a greater cross-sectional area than the cross-sectional area of the two combined 'passaigewaysg e artition closing the outer 5 ing them and for mixing-them still rther v as the pass through the openings, a nozzlel l 'for said burner spaced lfrom `said partition `and beting a single opening therein, and

means for applying the same pressure to the oil and to the air and'manually controlled 10 means for regulatlng the flow of oil 'and air to said burner independently of'each other.
