'Patent-ni Api-Q12, 1910.v`

Application led November 22, IBQB. Serial' No. 529,2()4.

To all Iwhom it may concern: l

' Be it known that I, Antnnn J. His-NunssEY, a citizen of the United States of America, residing` in the city of St. Louis and State of Missouri, have invented certain new and luseful In'iproveinents in Crude- Oil A Burners, of which the following is a full,

cle-ar, and exact description, reference being v'had to the accoxnpa n 'nying drawings, or1ning part ot' this specification. i

My invention relates to a crude oil burner more particularly intended for use in cook ing stoves, ranges, or heating stoves7 but which may also be used in connection with various other heating apparatuses.

Figure I a vertical longitudinal section taken through my burner, illustrated as it appears in use in a cooking stove. Fig. H a top or plan View o f the burner shown partlyl broken out. 'section of the top of the burner at the location of the detachable cap member. Fig. IV isa horizontal section taken on the line IV-IV, F ig. '1,' with a portion of the movable damper plate beneath said line broken out.

In the accompanying nates a pan that is adapted to be placed within the stove, or other device., to which heat is to be supplied in the use of my burner. The pan is intended to be only partially located within the iire box of the stove, and is surlnounted at'its outer end by an inner vertical housing member 2, preferably of 'cylindrical shape and `which has vcommunication with the pan at its lower end, duetto the= `:rresence oi anopening 3. At the location o t1 'is an oute, housing member 2 and preferably supported by vattachment to `said lhousing member through the medium of bolts (5. .The shell 5 is distanced from the inner housingmeniber to provide an annu-lar air passagcnay'be-v tween these members through which air may ascend, the separation of the members being preferably accomplished' by distancevsleeves surrounding the bolts G'and located between the inner housing and the surroumli ing shells-f v The" .grate 4 lat -the bottom of the innerg housing serves as a support for an oil receptacle which 'preferably comprises a main pot Fig. III is a vert-ical drawings z-l desi gthe opening 3 isa grate 4.. shell surrounding lthe inner "material than the 1n lnon-combiistible, the material l i l i i l 8 that may beof iron, or other suitable material, and a lining 9, or some less expensive ainpot, and which is used in making the lining being preferably clay. The lining '9 comin-isos a vessel portion that is seated within the u'1aiu` pot and extends across the top ot the main pot and then downwardly at its exterior, terminating ex terior of the pot. and at the bottom of the outer portion oit' the lining in a trap 10l which is adapted to serve as a receiver for the ovcriiowl otioil residue resu burning of the crude oil delivered to the pot of the burner.

The lprovision of the inex in an oil' receiver of acrude-oil burner, as herein contemplated, and the provision in connection with this inexpensive lining of a. trap by which the residue 'from the oil may be caught is an important item inl a crude oil burner, for the reason that such residue, which is not under ordinary conditions combustible, is contained in crude oil to such an -65 lting from pensive .lining 9 extent that the. eil receiver becomes very rapidly iilled with the residue so that there is, after short use of they burner, no adequate room. in the receiver for the combustible elements of the oil, unless the residue be removed from the oilrcceiver by a laborious process; and by reason of the further fact thatilin the absence otv a trap to catch the overllowing residue, it descends .in the burner and accumulates upon the burner parts beneath the oil receive-r to such extent as to cause early impedimentl to the How of hot air currents from the'oil'. receiver in which ycombustion'takes place tothe point at which heat from the products of combustion is to be utilized. By-providing my lining 9', which is removably. fitted to the main oil pot, Iprovide an oil tion v with the main oil catch. the overflowing residue of oil and which, being of an inexpensive nature, Inlay' be discarded and replaced by a new lining receptacle in' connecwhenever it' becomes unfit for service due to accumulation of oil residue therein, or caught in its trap.

.11 designates an oilconducting pipeleadsA ing te my burner and which terminates in a vertical position above the point at which the oil receiver in' the burner is located.

'95 pot which serves to" 2.0 therethrough into engagement with the concentral collar f sleeve 16 to hold the'ca provided at its a screw thread 14 located within the oil conducting pipe andterminating at its lower end in a conical valve 15. f'

16 is a regulatorsleeve surrounding the conducting pipe 11;.4 and provided with an internal screw thread that engages the external screw thread 12 of said pi e, in order that said sleeve may be adjuste verticallyT upon the conductin" pipeto regulate the degree of How. of oil rom the conducting pipe 11 through an orifice 17. in a 'closure member 18 carried b the regulator sleeve and which Iorifice is a apted to be controlled by the valve 15. The regulator sleeve 16 is adapted to be held in a fixed position by a set screw 19 mounted vin said sleeve and extending ductin pipe 11.

20 esignates a .cap of se mental'shape surmountlng the shell 5 and t e inner housing 2 and partially surrounding theV oil con ducting pipe 11 and the regulator sleeve 16. This cap is provided at its bottom and near its periphery with a flange 21 which is loosely seated within the outer shell 5, thereby permitting rotation ofV the cap for the performance of an oce as will herein- .a r appear. The cap is provided with a 22, of segmental shape, and which has screw threaded enga ement with the regulator sleeve 16, ,aroun cap is adapted to turn.

` 23 is a set and adapted to'bear against the regulator 'm movement after it" has been adjus toa position in which it is desired to `maintain it. i

24 is a liin er4 piece carried by the 'cap 20 and b whic rotationinay be readily impa to said cap.

25V is a nemovab e cap piece, provided with Va nger piece 2.6,

' the gap in the segment shapedjca 20. This cap plece'is detachably #Drin cap 20 at' the location seV support in part by theregulator sleeve 16,

part by a continuation 21*l of the flange of of the gap in slid cap, and said cap by beingdetachable permits ready access to the interior of the Inner shell 2, in order that oil present in the oil receiver may be ignited. 27designltes a perforated air admission per end of the inner late located at the up) ousing 2 and imi-nova y supported by said for said plate being housing. the supiport preferably provi4 ed by furnishin the plate with lips 28, (see Fig. IV), and notching e up ,end of the inner housing to reeeive t ese lips.

29 is an air regulator plate loosely seated on the air admission plate 27, and which is which the and which serves to close see Fig. III), and

13, the latter l the air admission plate.

this in view, the cap 20 is .ing `upwardl -will be readily provided with segmental shaped slots 30 adapted to register with the perforations in The air regulator plate is provided with a depending tubular leg 31, the passageway through which is lo cated beneath the oil conducting pipe 11 and above the oil receiver within the inner housing 2. The tubular. leg just referred to is ott'set from the center of the air regulator plate and extends throu h a central openin in the air admission p? axis of said air regulator plate `is eccentrically located relative to the center of the air regulator plate. As a consequence, when the air regulator plate is rotated above the air admission plate, the imperforate portions of the air regulator plate are so changed. in positions as to provide for the perforations in the air admission plate belng at one time mainly in an open condition, and at another time partially closed to a greater or less degree by the imperforate portions of the air regulator/[plate The quantity of air rising betwen the inner housing 2 and the outer shell/5, and which gains access to the interior of the inner housing within which they crude oil is there ore, provide for the adjustment of the 1 1 air regulator plate 28 through the medium of the cap 20, which is also adapted to actuate the regulator sleevel that controls the yflow of oil from the'I i'pe 11. With goed in engagement with the air regulatorI plate 29 by suitable means, such as that shown in the drawings, and which comprises a finger 20 extending downwardly from the cap 20 and arranged between a pair of lugs 32 projectfrom ,the air regulator.

understood that4 when the set screw 19 is retractedto a sufficient degree to permit .rotation of the regulator sleeve 16 on the oil conducting. pipe l1, While the set lscrew 23 is set to hold the cap 20 and the regulator sleeve l16 in firm engagement with each other, .the cap 2O will, upon being rotated, serve to actuate not onlyr the air regulator plate 29, but also the oil controlling` regulator sleeve 16 in such manner. that, 1f there is small amount of oil bein delivered to th; combustion chamber ofv t e burner, the passageways -through which air may enter into the combustion chamber will be restricted, commensurate with the quantity ofoil bein delivered to theicombustion chamber; Whi e, if the flow g ate 27, so that the stion chamber,

is supplied from the burner.

ing uncovered by the removal of said cap piece and through the tubular leg 17 ot the air regulator plate 29. as the oil burns, the air heated in the combustion chamber descends therefrom into the pan l to supply heat to the stove, or other heating apparatus with which the burner is associated.

It is highlyy desirable to prevent the hot i air and products of combustion entering into. the pan l from passing in rearward course Within the heating apparatus after they have entered the pan, in orderthat they may not esc'ape rapidly through the draft opening in, the heating apparatus, With consequent lessening of the supply of heat in the heating apparatus.v I, therefore, locate over the end of the pan'nearest the combustion chamber a hood la beneath 'which the hot air and prod ucts of combustion pass after entering into the pan, and provide a deiiector plate 33, which is supported by the side Walls of the pan and located back of said hood, this delector plate being provided with an upwardly extending rear portion that serves io retard the i'ioiv of the current of vhot air as it ,passes upwardly after flowing beneath the hoodia. A certain percentage ot' the hot a ir is therefore caused to ascend in the chamber of the heating apparatus at its end nearyest the combustion chamber of the burner,

while the remainder passes beneath the de- Hector plate 33; and, in so doing, ascends from the pan in the chamber to Which heat The defiector plate 32, is provided with a downwardly extending baille Se, which acts to restrict 'the passage or' currents ot hotair and products of combustion in a rearward course in the pan l. and cause them to be partially combined in :front of said battle in order that the oil that may descend into the end of the pan beneath the combustion chamber ot the burner may be consui'ned in this end of the pan, which is the one subject to the greatest degree or' heat, due to the proximity oi the combustion ch amber. As consequence, the oil descending into the pan is compietely consumed at the entrance-end of the chamber in the heating apparatus with which the burner used and th bene-tit ofthe heat derived ,from the combustion of oil at the point naiued is, therefore, received by the entire cliainbeiiin the heating apparatus. lvl/lith the object lin view of enhancing the combustion ot the oil in the pan l, at thev point to which reference has been made, I locatexin the bottom of the pan one or more transverse ribs 35, (see Fig. 1,) Which serve to restrain the low of oil in a rearward course, and retain it at the forward end of the ipan, where it will be subjected to sufficient heat for combustion thereot'll I Wish to direct attention to the fact that by surrounding the inner housing 2 of my burner by the outer shell 5, between which and the inner housing the air for the support of' combustion' in the combustion chamber passes, and the further act'that these members are .located above the outer end of the pan l, in which CombustionI also takes place, there is constantly a'hig'h degree of heat in the air passagewayleading to the combustion chamber and the air is highly heated in traversing this passageway and before itreaches the combustion chamber. It is vapparent that this highly heated air on entering the combustion chamber greatly enhances the'combustioi'i in said chamber, as compared with the admission of air that has not been subjected to a high degree of heat.
