HYDnocAnB'oN-OIL BURNER.

Application led January 1G, 1922. Serial No. 529,635.

To all w/zom t may concern:

Be it known that l, EVAN P. KILROY, a citizen of the United States, residing at Joplin, in the county of Libertyy and State of Montana, 'have invented certain new and useful improvements in Hydrocarbon-0il Burners 5 and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable those skilled in the art to which it-rappertainsVr to make and use the same.

The present inventiony relates toghydrocarbon burners. y

An object of the presentinvention is to provide a burner which is adapted to feed a quantity of air to the centralportion' of a flame for insuring complete and satisfactory combustion of thelbody of gas/issuing `from the burner opening from center to' circum-r ference y and to ,thus produce a burner which is not only more efficient, butwhich is capable of radiating more heat. y

it is well known that in prior oilburners at present in use,'-the centerk of the' iiame is usually of a' dull blue color while the outer portion of the flame is of a bright red nor yellow color, and isfar hotter than theinside or blue portion...y j i lt is therefore another object of this invention to do away with this dull bluecentral portion of the ame and to render the flame of an even glowing white color and of n correspondingly increased heat intensity resulting in the more thorough andcoinplete combustion of the gas or vaporfand conse-p quently a more efficient burner from the standpoint of fuel consumption `and from the standpointof production of heat energy.y

The present invention further aims at the provision of a ynovel device for,feedingylairto the 'central portion of the llamek for prometing combustion thereat. p

A still further object of the invention is to provide a novel combination of fuel and air feeding pipes for automatically yaporiz` ing or gasifying the liquid fuel and for heating the air prior to delivery to the middle of the` burner and also for protecting such vaporizingandair heating pipes from the intensity of the flame at such portions of the pipes which pass through the flamef The invention further aims at theprovi# sion of a burner of this type, whichpossesses the above enumerated characteristics, and which may be used in the fire box of a stove and which may be supported upon the grate n perforationv 16.

. out the several views,

F ig. 1 is a side elevation partly in section,

mofa burner constructed according to the present invention and shown as resting upon grate bars of conventional form; and,

Fig. 2 is a top plan viewthereof. Referring to the drawing, the burner comprises a base platelOwhichz is of any suitable construction and/which preferably has a marginal,'dependingfiange 11 arranged for spacing the body portion of the plate 10 above a support toperinit free access and circulation of air atvthetunder side of the plate. Thel plate 10 vmayA be of elongated rectangular construction as shown, and is adapted to be fitted in the fire box of astove or the like andy to be ysupported upon 4grate bars 12.

ing pyramidal projection 13 forming an air feeding mouth and the end walls of which are slotted or recessed as at 14 to receive u The plate 10 is provided with an upstandi therethrough the horizontal portion 15 of vaporizing pipe, the portion 15 having a jet or outlet perforation 16 in its upper side and at the central portion of .the rpyraniidal mouth 13. The projection ,13 has a relatively large upper open end y17 `providing ample'air space beneath and about the pipe ,portion 15, soy that airis permitted to freely co-n'ii'ngle with the gas escaping through the The vaporizing` pipe 15 has one end turned downwardly through a slot 18 formed in one end of the plate 10 and extending from the vbase of the mouth 13 to the adjacent extremity of the plate, the lower end of the pipe 15 being closed by a cap 19 for inaintaining vapor or gesunder 'pressure in the pipe. The other end of the pipe 15 is curved upwardly or returned in spaced relation above the portion 15, as at 20, and such re- .turn portion 20 extends beyond the closed end of the pipe 15 and is carried downwardly through such slot 18 in the plate 10. This latter end of theV pipe is the inlet end and is externally threaded as at 21 to receive thereon adjusting and supporting nuts 22 which are clamped against opposite sides of the plate 10, the upper nut preferably having an interposed bracket plate 23 beneath the same and which is adapted to project beyond opposite sides of the slot 18. rlhe lower extremity of the threaded portion 21 of the vaporizing pipe carries a reduction coupling 24 to which is connected a relatively small fuel feeding pipe 25 adapted to conduct kerosene or other suitable hydrocarbon to the vaporizing pipe. 1f desired, the threaded end 21 of the pipe may have metal filings or other suitable thread-like substance 26 therein for breaking up the fuel and for insuring the heating and filtering of the same as it passes into the vaporizing pipe.

rl`he other end portion of the plate 10 carries an air feeding pipe 27. The pipe 27 has a substantially vertical or shank portion, the lower extremity of which is threaded, as at 28, and is adjustably secured through a perforation in the plate 10 by clamping nuts 29 which bind against the opposite sides of the plate 10. The air pipe 27 may therefore be secured in various vertically adjusted positions through the plate 10 and may also be swung upon its longitudinal axis into various angular positions with respect thereto. The lower end of the pipe 27 is closed by a threaded cap 30 and the latter carries upon its upper end a yieldable washer or gasket 31 against which is adapted to seat the lower end of a sleeve valve 32 mounted on the threads 28 and adapted to be turned for movement lengthwise upon the pipe 27, toward and from the yieldable seat 31. The pipe 27 has one or more perforations 33 in its side immediately upon the seat or gasket 31, and such openings 33 are adapted to be more or less uncovered by raising the sleeve valve 32 upon the threads 28.

The upper end of the pipe 27 is curved or bent laterallyto form an over-hanging portion 34, the free extremity of which is curved downwardly with its axis substantially co-axial with the axis of the mouth 13, when the air pipe is adjusted as shown in Figs. 1 and 2. The over-hanging portion 34 is threaded at its lower end andk supports a combined spreader and air feeder. The spreader and air feeder is composed of a pair of disks 35 and 36 which are secured together by rivets 37 and spaced apart by washers 38 carried upon the rivets 37 and interposed between the disks 35 and 36. The disk 35, shown as the upper disk, has an internally threaded sleeve portion 39 which is threaded on the pipe 34 and the sleeve 39 opens through the disk 35 so as to convey air from the pipes 37 and 34 to the space between the disks 35 and 36. |The lower disk 33 has a central depending projection 40 of conical configuration providing a deflector adapted to spread the flame or gas which rises from the perforation 16 to not only enlarge thev frame for the purpose of insuring complete combustion, but also for protecting the over-hanging portion 34 ofthe air pipe and the return portion 20 of the vaporizing pipe, which latter is adapted to extend across 4the top of the combined spreader and air feeder.

In operation, fuel is admitted through the pipe 25 to the vaporizing pipe 26, 15. The combustion of the gas issuing from the jet opening 16 heats the over-hanging portion 2O of the vaporizing pipe and vaporizes the hydro-carbon and places the vapor or gas thus formed under considerable pressure in the pipe portion 15. The gas under pressure issues from the opening 16 and rises with considerable force against the spreader which deflects the gas or fiame outwardly about the marginal edges of the disks 35 and 36. The heat of the flame as well as the suction produced at the middle portion of the flame creates a suction in the pipe 27 with the result. that air is drawn in through the openings 3.3 and is caused to rise in the pipe 27, be heated in the overhanging portion 34, and finally distributed uniformly from the spreader and deflector to supply air to the middle portion of the flame. The quantity of airdelivered to the middle portion of the flame may be regulated by raising and lowering the sleeve valve 32'for more or less covering the openings It is apparent that the base plate 10 may be seated in the fire box of a stove withthe flange 11 of the base plate resting upon the grate bars 12. 1n this position, the ends of the vaporizing and air feeding pipes project downwardly between the grate bars so that the fuel pipe connection 25 may be made in the ash pit and the burner may receive air upwardly through the mouth 13 from the ash pit as well as through the pipe 27 from the ash pit. This permits the desired regulation of the burning of the flame by regulating the usual air checks or registers in the doors of the ash pit and fire box compartments.

It will also be apparent that the air pipe 27 may be adjusted as above explained, and the vaporizing pipe may also4 be adjusted not only axially upon the nuts 22, but lengthwise in the slot 18, the slot 18 facilitating the assemblage, knocking down and regulating of the parts of the burner.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
