OIL BURNER.

Application filed May 27,

This invention appertains generally to new and useful improvements in burners and has more specific reference to a novel and simplified oil burner.

The primary object of the present invention is to provide such a burner of the nature stated including an inverted burner nozzle and a super-heater or generator whereby to insure a steadier and stronger flow of gas from the burner nozzle7 thereby eliminating the danger of blow backs.

A further object of thepresent invention is the provision of a new and novel type of burner nozzle.

Another object of the present invention is to provide such an improved burner of the nature stated having associated therewith safety means for automatically cutting off the supply of oil should the burner become flooded due to the going out of the burner4 nozzle.

A still further object of the present invention is to provide such a burner ofthe nature stated which while simple in construction, is nevertheless strong, sturdy and durable, one which is effective and efiicient in its operation7 one which can be manufactured and placed on the market at a reasonable figure and one which is well designed for the purposes for which it is intended.

lVith these and numerous other objects in view, the invention resides in the novel construction, combination and arrangement of parts to be more fully hereinafter' described, illustrated in the accompanying drawings and particularly pointed out in the appended claims.

In the drawings forming a part of this application and wherein like characters of reference denote corresponding parts throughout the several views:

Figure 1 is a side view, partially in section, 'f an oil burner constructed in accordance with the present invention.

Figure 2 is a top plan view thereof.

Figure 3 is a Sectional view taken on line 8 3 of Figure 1 looking in the direction of the arrows.

Figure l is a sectional view taken on line 4 4 of Figure 1 looking in the direction of the arrows.

Figure 5 is an enlarged detail sectional view of the burner nozzle.

Reference now being had more particu-- 1 larly 'the accompanying drawings wherein 1926. Serial No. 112,105.

vfor the purpose of illustration has been disclosed a preferred embodiment of the present invention, the letter A generally indicates the present improved oil burner and B the safety moans associated therewith for automatically cutting olf the supply of oil thereto.

`rlhe burner A comprises in its construction a suitable base 10 from which rises the supporting standard 11 carrying intermediate its ends, a burner generally indicated by the numeral 12 and which may be of any conventional or preferred construction. The burner disclosed herein is of the Bunsen type and comprises a circular bottom wall 13 and the annular flared side wall 14. Fitted within the burner 12 and spaced from the bottom wall 13 thereof to provide an oil chamber 15 is a block or plate 16 provided with the plurality of burner openings 17. Secured within the bottom wall 13 of theburner and communicating with the gas chamber 15 therein is one end of a gas pipe 18, said pipe being provided with a plurality of alined lighting openings 19 and having its opposite ends communicating with a suitable source of gas supply.

rlhat portion of the standard 11 above the burner 12 is provided with a plurality of vertically disposed flutes 2O which provide flues for the gas emitting from the burner l2. Mounted upon the upper end of the standard 11 is a hollow frusto-conical gas generator 21 adapted to. be heated by means ofthe burner 12. Leading into one side of the generator 21 and communicating therewith is an oil supply pipe 22, the opposite end thereof communicating with a suitable oil containing tank or the like 23. Installed within the length of the oil supply pipe 22 is a suitable needle valve 2d, the purpose of which will be setv forth'more fully hereinafter.

rllhe generator 21 is provided at a point diametrically opposite the oil supply pipe 22 with the substantially vertically disposed gas outlet pipe 26 which constitutes al super heater, the upper end of said pipe being curvedy inwardly and downwardly with the terminal 27 thereof positioned directly above the flues 2O and carrying the burner nozzle 28.'

rlhe burner nozzle 28 is of a novel construction and as disclosed to advantage in Figure 5, comprises a head 29 having a reduced nipple 30 which is threaded within the terminal 27 of the pipe 26. said nipple ined l yscale can then be readily removed by simply removing the burner nozzle. Thus, it will be seen that the burner nozzle will be eec-V tively prevented from clogging and that the terminal lof the gas outlet pipe 26 can be quickly and easily cleaned.

In order to operate the present improved oil burner the valve 2l is first opened to per- Vmit a small amount of oil to flow into the generator 21 after which the gas is turned hito the gas pipe 18 and lighted at the small hole 19. The flame will follow along the series of openings lQAuntil it reaches the burner 12 and lights the same. The heat from the burner 12 will heat the generator 21 converting the oil contained therein into a gas, this gas filling up the generator and finally passing upwardly through the gas outlet pipe 26. Vhen the gas pressure is sulficient to emit at the burner nozzle 18, the flame from `the burner 12 coming up through the flues 2O will ignite the gas coming from said burner nozzle and the burner 12 should then be turned off. The flame from the burner nozzle 2,8 willbe directed against the generator 21 which will cause the rapid generation of the gas therein. The flame after striking the generator 21 is deflected and this heat contacting with the gas outlet pipe 26 superheats the gas before it leaves the burner nozzle 28 thereby increasing the efficiency of the said burner. Y

lt will of course be understood that alcohol may be used instead of gas for starting the burner and `Wlien"such alcohol is used, a sufficient-L amount of it is permitted to flow through the pipe 18 until it reaches a predetermined level in the burner 12. The alcohol is then lighted and the subsequent operation is the same as has been out-lined above.

The present invention also contemplates the provision of the `novel means B for automatically stopping the iiow of oil to the generator 21 should the same become flooded due to` the momentary interruption in the roil supply and thegoing out of the burner nozzle. Such means embodies a solenoid 33 mounted upon the oil supply pipe 22 through the medium `of a suitable bracket 34. The solenoid is provided with a slidable plunger'l pivotally connected as at 36 to the needle valve operating arm 37. Leading from the solenoid 33 are the wires 38 and 39, the former being suitably secured within the burner plate 16 in the burner 12 while the wire 39 runs to and is connected with a battery 40. Lead- Formed concentrically goes out due to a momentary interruption in the oil supply and the oil supply is again resumed, the said oil will lill the generator 21 and will pass upwardly through the gas outlet pipe 26 and through the burner nozzle 28.

The oil from the burner nozzle will then run through the flues 20 filling up the burner 12 and as soon as the level of oil reachesthe Wires 38 and 41, an electric circuit will be completed through the solenoid 33 and battery 40. The solenoid will then be energized whereby to cause the .moving of the plunger and the .closing .of the needle valve 24.

From the foregoing, it will be appreciated that there has been provided a novel and simplifiedoil burner which will accomplish all of the objects and perform all ofthe functions enumerated as being desirable in the statement of the invention set forth hereinabove and it is to be further understood that. changes in the details ofthe presentinvention may be resorted to without departing from or sacrificing the Vspirit ofthe invention sol long as such changes `fall within the scope ofthe appended claims.
