WILLIAM C. MCKESSON, on CHICAGO, ILmNoIs OIL BURNER Application filed May 27,

V ation "ofothe burner is greatly affected by 14 the presence of carbon or other like foreign matter which results from the burned 011. Allowing any deposits of carbon upon the burner or any other elementof the oil burner which is within heating range of theflame,

will tend to lower the efficiency of the appa-' ratus; It is, therefore, one of themany 0bje'cts of this invention to provide an oil burner with a simple arrangement of parts for efl'ecting the removal of carbon deposits or t-helike.

Astill further object of this inventionisto provide an oil burner which adapted to be usedin connection with a gravity fuel feed 7 arrangement. Toaccomplishthis and to obtain the best results it is advantageous that the oil be vaporized prior to its introduction to the flame. It is, therefore, one of the objects of this invention to provide an oil burnor which will accomplish this purpose.

' Otherobjects will appear hereinafter;

The invention consists in-ithe novel combination and arrangement of parts to-be here in'a'fter described and claimed. a

The invention will be best understood by reference tosthe accompanying drawing showing the preferred form of construction, and in which:

1930." se'riain asez is. p A p t Referring particularlytofFigl -1,illu strating a conventional heating apparatusj with which my oil burner may beassociatedpthis apparatus includes a body 10, definingaconibustion chamber 11 anda'pit 12, the 'pit .12 being separated from the combustionjcham} ber by the usual-grates 13. Communicating with the pit 12 is a, draft and clean-out door With an apparatusof this character or of similar character my improved oiljburner is adaptedto be associated.

My improved oil burner in the present instancepreferably includes apipe member 15 1 having its lower end. portion provided with screw threads '16. Threaded upon this pipe 15 is apan or dish element 17 v which includes anupstanding. annularfiange-18. Abovethe pan or dish-like element 17 is a distributor head 19. This distributor j head 19 inftheg'fl'i present instance includes a nipple 2O thread-1 1 ed upon the pipe 16, and threaded upon this nipple is a cup 21. This cup 21 includes at spaced intervals upstanding lugs or finger s 22, and the inner edges 23'ot these fingers terminate into tapered projections 24 forrea-j sons hereinafter set forth. I I

Thecup 21 is preferably filled with a suitable fire clay 25 or the like or other, refractory ,is'ub'stance for'heat intensifying purposes, 89 Surrounding the upper end portionofthefl V pipe 15 is an outer pipe 26. This outerpipev 26 isof a diameter suflicient to afl'ord 'pos'i tioning of the pipe .26 between the lugs or fingers 22, and the lower edge of the pipe26 35 is beveled upwardly and inwardly as at 27 thislower edge 27 being adapted to seat upon the projections 24. V I a Threaded upon the end portion-of the pipe 26 is a body 28 havingla hollow interior 29 to provide a vaporizing chamber. This body 28 is threaded as at 30-to the" pipe 26. As shown, the upper end portion of the pipe 15 extends through the pipe 26- with its end into 7 the chamber 29, and threaded upon this end is a bafile head 31. This bafile head 31 ineludes oppositely disposed parallel grooves I 32 which merge [at their cornersin'to outlet grooves .33.

The end 34 6f thepipe 26 is preferably 9- 7 tapered upwardly and inwardly to provide knife shaped edges which engage in the ports or notches 49 as shown, for reasons hereinafter set forth. v

The body 28 is provided with a central opening 35, and threaded in this opening is a nipple 36. Threaded into thisnipple 36 is a plug 37 This plughas threaded therein a set screw 38, and formed preferably as an integral part of this set screw is a depending scraper bar 39 which -extends downwardly substantially through the pipe 15 to a point adjacent its lower end portion. Fixed z-to the pipe 15 adjacent the pipe 26 there is also 'vide on the under surface of the body 28 concentrically arranged ribs '46 which will resist the cracking ofthe'body 28 reason of the intensityv of the heat.

" Associateclwith the pan or dish like I i ber 17 isan .overflowpipe47 which is directed to deliver excessive -oil fuelt oa bucket or other basin (not. shown) controlling a suitable valve structure such as described in my co=pending application Ser. No. 456,245 jliled byfme on even date in the United States iPat entOfiiceg Also associatedwith' this -basin or dish like member is an air delivery pipe 48 which has its end portion confined inthe draft pit12 of the stove. I v

*ln-usetthe several parts are assembled in the mannerillustrated.inFig.v,2 with the basin or'dish' like 17' threaded up against the nipple 20 whichlhas the effect of alock nut locking the several, parts in their respectivepositions, Theoil burner is then ns di h at a para by P j ectingthe pipes 47 and '48 through the grates with the basinor dishlike member supported upon the grate. Ifthe grate be ofva-duplex type the mountingofthe burner in the heating'apparatus'may be greatly facilitated by pen n t te ,P r iti her r s 4 and 48 to be projected therethrough. LHowever,

ifthe grates are ,not of'this type suitable open- V ings may be formedin-the grates .fOI'jlillG PI'Qfi j ection of these pipes.

Ofil or other suitable :fuel isadmitted into thepipe15. By'gravity it isforced upwardly through this pipeiintoithe vaporizing chamber 29. The oil finds its entrance into this chamber through the outlet grooves 33. It

willibe noted that theend 34 of'the pipe 26 pro ects a predetermined distance "into this chamber so that consequently a certain amount of oil will find lodgement in this chamber. From the chamber the oil passes after it reaches a certain level, through the notches or ports 49 formed in the underside of the baffle head 21, into the pipe 26' and downwardly through the pipe 26 into the distributing cup 19 and fromawhence into the basin or dish like member 17. Any excessive amount of oil at this stage of operation will be drai-ne clthrough the pipe 47. At

this stage ofthe operation the valve controlling the supply of oil through the pipe 15 is closed The oil in the basin or dish like pan 17 is ignited; This can be accomplished by; suitablelight or ,by means of .an: inflammablepiece of material such as paper or the like which. is ignited and projected intodthe basin. or dish like member 17. The-cheat thus generated will heat the vaporizing chamber and consequently the oil therein willlbe come vaporized and move through notches 49 and downwardly through the pipe 26 ,into con tact with the Iflame of the oil inithe member 17 and thereby become ignited The valve is now openedto admit the .oilthrough the pipe 15 and asthe" oil enters the chamber 29 it becomes vaporized rand emerges .,.'froin the pipe 26in a vaporized condition tobe ignited andjburned. v

It is a known fact'that'lall oil will dispose carbon on ;theheat ed parts and asv indicatedit is one of themany objects ofnthis'linven tion to provide asimple meansff'or removing this carbon without disassembling theburnen.

Any carbon disposedon the pipe 15 is-re moved by thecarbonremoving bar T39 YThis is. accomplished by rotatingthe vaporizing chamber .28, which in turn 'willrotate the bar 39, rubbing the'longitudinal edges there of against the interior surface of the pipe 15'.v Carbon is removed from the endv34 which constitutesa seat for the baliiehead 31 and this is likewise accomplished byfrotatin'gthe' vaporizing chamber which ,will cause the notched portions 49 of the bafiiehead'to rub over the knife like edges of the end'134 and thereby to cut the carbon fromthe balfle seat.-

Carbon is likewiseremoved from thelower end portion of the pipe '26 upon rotation'of the vaporizing chamber 29 Upon rotation of this chamber 29 the pipe 26 will be ro-s tated therewith and they projections :24 will scrape the beveled edge27 of thepipe. 26 and consequently remove the carbon deposits therefrom. 7 g As shown the body 28 is provided with a plurality of radially extending fins 28 for conductive purposes and in rotating -.thishody and its several parts for removing the carbon the user may .apply'the end of a; poker or other instrument to these ends to facilitate this rotation g Q a 4 Any carbon deposits within the'pipe 26 are removed bythe bar 41whichis accomthat the user of an oil burner such as herein.

described can readily remove the carbon deposits which diminish the efliciency of the burner by simply rotating the oil'burner i the manner herein described. r

The present invention constitutes an improvement over that disclosed in my United States patent granted December 31, 1929, Patent No. 1,741,868. r

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification, without departing from the spirit of the invention.
