HYDROOARBON-BURNER.

Specification of Letters Patent.

Patented Feb. 17, 1920.

Application filed .Tune 30, 1919. Serial No. 307,669.

To all whom it may concern:

Beit known that I, PAUL B'. BUDAI, a subject of the Emperor of Austria-Hungary, residing in the county of Montgomery, near the cityy of Dayton, State of Ohio, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention relates to. new and useful improvements in hydrocarbon burners.

One ofthe objects of my invention is to provide a cheaply constructed. and efficient burner that is adapted to be easily inserted in oil and gasolene stoves, for cooking and heating purposes.

Another obj ect of my invention is to eliminate the use of asbestos and other kinds of wicks that frequently need replacement and are apt to, clog up. the burner whenV in use. Instead of these wicks, I provide a steel wool lller or atomizer that does not need replacement, it does not clog upthe generating tube, and breaks up. and sets. in whirling motion, the oil prior to its issuance from the discharge oriiice.

Another obj ect of the invention is the provision of a discharge oriiicethat is not diflicult to drill, said orifice receiving a specially constructed pin thatl causesthe gas to issue around. it in tubular form, causing it to unite with more air afterV it. leaves the discharge opening. Another object of the invention is to` provide ak channel toY receive the oil which comesI out with the gas when too much oil is admitted to the generator tube. before it is properly started, said oil being directed by said channel to a. tube through which it is drawn off.`

Another object of the invention is the provision of a lid device that may be readily removed to aord instant and easy access to the discharge orifice to. loosen up the carbon around the pin: therein.

Another object ofthe invention is to provide a removable trough-shaped device` for priming or initially heating the generating tube, further means. being provided; to keep it continuously heated while in operation. Itis a furtherobject ofthe invention to provide. for this latter purpose, a manifold whichA is constructed in a single casting.

Other important and incidental objects n '.willlbe brought outin the following specification, and particularly set forth in the subjoined claims.

The preferred form or embodiment of my invention is illustrated in the accompanying drawings, of which Figure l is a top plan view of my improved hydrocarbon burner. Fig. 2 is a sectional view of said burner on the line A-A of Fig. l. Fig. 3 is a vertical sectional view of said burner on the line B-B of Fig. l. Fig. 4 is a sectional view of the mixing chamber taken on the line O O of Fig. l. Fig. 5 is an enlarged vertical sectional view of the outlet end of the generator tube. Fig. 6 is an end` view of the same. Fig. 7 is a horizontal sectional view thereof. Fig. 8 is a detail plan view of the priming device. And Fig..

9. is an end view of the same.

Throughout the specification and drawings, similar reference characters denote corresponding parts.

Referring to the accompanying drawings, the numeral 1 designates a conduit or manifold casting which at its outer end terminates in a portion 2 that is preferably hookshaped in cross section as shown in Fig. 3. Provided on the top middle portion of the casting l is a hollow ridge or rib 3 which extends from its enlarged forward end portion to a point a short distance from its other end, forming with the latter a shoulder 4 that receives the cross portion 5 of a removable priming trough 6 preferably shaped like a tuning fork whereby each leg thereof may rest on top of the horizontal portion of the. conduit l, on a respective side of the rib 3, for a purpose to be hereinafter described.

The inner wall 7 of the end portion 2 of the casting l, is preferably vertical, containing a short distance above the level of the ridge 3, an opening into which is tightly driven a flanged plug 8. The latter has provided in its end wall a discharge orifice 9 which communicates with a bore l0 in the plug thatv is adapted to receive the hydro- Icarbon mixture from a generating tube 11 projecting end 111 that receives a n eedle valve 15 by means of which the flow of liquid fuel to the generating tube 11 may be controlled. (See Fig. 1.)

The downwardly projecting end 13 of the needle valve housing 12 has an annular flange 16 which rests upon the horizontal end portion of a sheet metal plate 17 that inclines downwardly to a vertical portion which is firmly secured, by means of a screw 18, to the front end of the horizontal portion of the casting 1. The downwardly projecting portion 13 of the housing 12 has a reduced threaded portion 19 that passes through `a hole in the horizontal portion of they plate 17, a nut 20 being applied to said threaded reduced portion for the purpose of firmly clamping the outer end of the plate 17 against the anged portion 16 of the valve housing projection 13. By the means thus described, the needle valve housing 12 and inner end of the generating tube 11 are rmlyy supported by the inner end of the vconduit casting 1.

Provided in the generating tube 11 is a steel-wool ller 21 which does not deteriorate like asbestoswicking or like material. Furthermore, it does not clog up the orifice. 9. The liquid fuel in its course therethrough is thoroughly broken up or atomized prior to its entrance to the discharge orifice 9.

As before stated, there is provided for this orifice, a pin which is preferably round with the exception of its two ends,-and they are flat to act as flanges to hold said pin, which is designated by the numeral 22, in the orifice. The diameter of this pin is less than that of the orifice 9 to permit the atomized fuel a minute exit passage around the pin, which causes it to issue from the orifice as a spray which assumes a somewhat f tubular form. As it leaves the orifice, the fuel spray is mixed with air that is conducted to it as follows.

Referring to Figs. 2, 3 and 4, there is provided on each side of a horizontal channel member 23 projecting into the enlarged p0rtion 2 of the casting 1, an air inlet passage 241i which directs the air toward the orifice 9 as shown by the arrowsjn Fig. 4. The mixture resulting from the cominingled air and atomized fuel, passes around the outer end of the channel member 23 into the passage 25 as indicated by the arrows in Fig. 3, impinging against a rib 26, by which it is directed upwardly beneath a series of holes 27 provided in the top of the ridge 3 of the casting 1. As the gas, becoming ignited, passes inwardly beneath the apertured ridge 3 of the casting, it supplies continuous heat to the generating tube l1 above for the purpose of keeping it at a temperature which insures a thorough vaporization of the liquid fuel that passes' through the steel wool ller 21 therein. f

For the lpurpose of preheating said generating tube 11 when the burner is started, the trough 6 heretofore describedv is c mployed. By means of a handle 28 that 1nclines outwardly from the inner end of said trough'member, it may be readily placed in position on top of the horizontal portion of the casting 1, with the ridge 3 betweenits prong portions. The alcohol or other priming fluid which it may contain, is then ignited, with the result that the heat of combustion passes upwardly around the vaporizing tube 11 for the purpose of thoroughly preheating the liquid fuel therein, after which the heat produced from the ignited gas passing upwardly through the holes 27 in the ridge 3, will heat said tube suiiiciently for generating purposes as long as the burner is in operation.

If perchance any oil should pass through the orifice 9 during the starting of Vthe burner, said oil` will drop upon the concave top portion' of the channel member 23 from which it will fall into an outlet tube 28 screwed in the bottom of the casting l. On the bottom of the tube 28 is a petcock 29 for the purpose of draining out the oil at desired intervals. (See Fig. 3.)

Referring to Figs. 2, 3 and 1, there is provided in the topof theenlarged end portion 2 of the casting 1,- a hole 30 that is normally closed by a lid 31. By removing this lid, ready access may be had to the pin 22 for the purpose of removing any carbonwhich may collect thereon. v

After being thoroughly mixed with air in the mixing chamber before described, the vaporized fuel passes into a conduit or manifold 32 at righty angles to the conduit l.

This manifold 32'communicates with a hollow circular burner 33 supported by legs 34, said burner containing a series of raised portions or ridges 36 in its top portion, said ridges being disposed around a hole in the center of the burner and being spaced a sufficient distance apart and run at approximately right angles to one anotheryto permit air freely to circulate between them. They are 'near' enough together, however, that should one burner ridge become extinguished, it willy be immediately ignited by the surrounding ones. Provided in the ridges 36" are slots 36a through which the gas flame issues, said slots being disposed in the same direction to permit them to be readily formed by a cutter whose position neednot be changed for each slot, as is the case in cutting radial slots. j

Firmly securedby means of a screw 37 within the burner 33 is an inclined deiiector 38 for the purpose of insuring a Vthorough diffusionvof gas through the burner.

An additional burner 39 is provided on the rightghandside of the casting 1 for use when desired.L Communicating with the burner 39, which is supported by legs 40, is a conduit 41 that is preferably the integral part of a valve housing 42 which receives gas from the conduit 1 through a transmission tube 43. The latter terminates at its lower end in a seat for a puppet valve 44 carried by a stem 45 threaded into a bushing 46 which is screwed into the lower threaded end of the valve housing 42. When this valve is lowered, communication is established between the tube 43 and conduit 41 through the valve housing, whereby the burner 39 will receive gas from the conduit l as well as the burner 33. By means of the valve 44 it is easily possible to shut oil' the burner 39 when it is not needed. (See Figs. l and 2.)

There is also provided in the burner 39 a deflector 46 which is similar to the dellector 38 in the burner 33 and which performs a similar function.

Havingl described my invention, I claim:

l. In a device of the type described, the combination with a gas receiving conduit, of a vaporizing tube in communication therewith, a plug inserted in the end of said vaporzing tube that communicates with the conduit, said plug containing an easily drilled discharge orifice, and a round pin of less diameter than the orifice, provided in the latter to aord a minute passage for the gas around its periphery, the ends of said pin being attened to hold it in said orifice.

2. In a device of the type described, the combination with a gas receiving conduit having an upwardly extending enlarged end, a vaporizing tube in communication with said end, a horizontal channel member in the latter, below the outlet end of the vaporizing tube, adapted to receive unvaporized fuel from said vaporizing tube and discharge it from its outer end, and an outlet for said fuel in the bottom of the enlarged end of the conduit below the discharge end of the channel member.

3. In a device of the type described, the combination with a horizontally disposed gas receiving conduit, a rib on the top portion of the latter, a vaporizing tube horizontally disposed above said rib, and a priming trough shaped somewhat like a tuning fork, to straddle said rib below the Vaporizing tube.

4. In a device of the type described, the combination with a horizontally disposed gas-receiving conduit, a rib on the top portion of the latter, a shoulder formed between one end of said rib and the top portion of the conduit, a vaporizing tube horizontally disposed above said rib, and a priming trough shaped somewhat like a tuning fork, whose cross portion rests upon said shoulder and whose leg portions straddle the rib below said vaporizing tube,

5. In a device of the type described, the combination with a horizontally disposed gas-receiving conduit, a hollow rib on the top portion of the latter, containing gas issuing holes, a shoulder formed between one end of said rib and the top portion of the conduit, a vaporizing tube horizontally disposed above said rib, a priming trough shaped like a tuning fork whose cross portion rests, upon said shoulder and whose leg portions straddle the rib below the Vaporizing tube and a handle inclining outwardly from the inner end of said priming trough, for placing it in position on the top portion of said conduit.

In testimony whereof I have hereunto set my hand this 28th day of June, 1919.
