The top of the burner is closed when in operation either by a cover or b y the cooking utensil or utensils placed thereon. As shown, the upper margins of said wall B are of the same size and shape as the hole a in the stove-top, so that covers and cooking utensils adapted to fit the stove may also be placed upon the burner when theV latter is upon the stove. The particular burner illustrated in these rfigures is made of elongated form to fit the single elongated hole comvtwo circular covers.

, brick, pumice-stone, or other porous material,

or of a refractory granular substance, such as sand.

At the middle of the burner, and extending longitudinallyfrom end to end thereof, is an air-chamber F, which communicates with the external air at the ends of the burner by means of suitable inlet-openings f' f', Fig.

Y2. YAt the middle of the top wall ofthe said air-chamber F is located a transverse oil-pas- 1 sage G, one end of which is bent or curved downwardly toward and extends to a point near the bottom of the trough D.

' G' is the oil-supply pipe,which extends into the air-chamber F of the burner from one end thereof and is connected with the upper part of the oil-passage G. y Over the oil-trough D, and Vbetween the air-chamber and the adjacent part of the wall B, is formed a combus- Jtion-chamber H, and between said air-chamber and wall B, at the opposite side of the burner, is a passage or opening H', through which the flames and heated products of combustion from the combustion-chamber may pass downwardly through the bottom of t-he burner into the stove.

` In the particular construction of the burner herein shown the-several parts of the burner are cast inone piece, the several walls composing the parts being disposed as follows: The -lower walls of the air-chamber F and of the oil-trough D are formed by a horizontal bottom plate B', cast integral with the vertical wall B of the burner and forming a contin'uation of the rear part of said wall, as clearly7V shown in Fig. l.

chamber F and also cast integral with the side wall B of the burner, said plate B2 being connected with the bottom plate B' by means of a vertical wall B3. Between said wall B3 and the adjacent part of the vertical wallB of the burner is formed the passage H',through which products of combustion from the combustion-chamber H may pass downwardly in to the stove. At its margin adjacent to the combustion-chamber H the horizontal wall B2 is provided with a depending flange b', between which flange and the ange b is formed longitudinal slot or opening f2, through which tion-chamber. At each end of the chamber F is a transverse wall B4, which extends en tirely across the end of the burner and forms the end wall of t-he said chamber F and also the end walls of the passage H', the combustionchamber H, and the trough D. In its part within the air-chamber the wall B4 terminates somewhat above the bottom plate B', so as to form the inlet-opening f', through which air enters the said chamber F. Said wall B* is connected at its upper margins with the horizontal top wall B2, which latter is extended at its ends at b2 b2 to the ends walls of the burner, said parts b2 b2 being preferably arranged in a plane above the main part of said wall B2. Outside of and parallel with the wall Btl is another .transverse wall B5, con- `nected at its lower margin with thebottom plate B' of the burner and extending upwardly to a point near the lower surface of the horizontal wall b2, so as to leave an air-inlet openf2 by the vertical passage f3 between said walls B4V and B5. The said wall B5 is desirably provided with a sliding valve plate or damper B6, adapted to control the openingf', and thereby enable the influx of air to the heating-chamber to be regulated as desired. The passage G isu preferably cast integral with the top wall B2 of the chamber F and extends transversely of the latter, and is provided with opens at the bottom of the trough D, preferably below the bottom of the porous bed E therein, as clearly shown in Figs. l and 3. To support the said porous bed E above the bottom of the trough D and thereby afford a space beneath said bed through which the oil may freely ilow from the passage G', I have herein shown open metal frames e eas placed in said trough under the porous bed; but studs or projections cast upon the bottom of the trough y IOO t ing f', which communicates with the opening l IIO Va downward extended tubular part G2, which 8o air'from the chamber F enters the combusducts of combustion from the combustionf` chamberH pass horizontally over the top of the airchamber F and then downwardly through the passage Il', from which t-hey pass to the smoke-exit passage of the stove, as indicated by the arrows in Fig. 3b. The burner is preferably placed in the stove with the first started and combustion is comparatively slow by reason of the parts being cold) will accumulate in the bottom of thechamber F,

, and will there remain until vaporized by the heat of the parts. Air entering the air-heating chamber F through the passages f f f3 at the ends of the latter, as indicated bythe arrows, passes to the combustion-chamber above the porous bed through the slot f2 The walls B B2 B3 of the chamber F are highly heated by the products of combustion passing over or around said chamber in the manner described, so that the air within the chamber beconies highly heated before its passage to the combustion-chamber with the result of greatly facilitating the rapid and complete combustion of the oil. The air-.entering the chamber is also heated to some extent by contact with the walls of the passages f3 f3.

, Another, and for some reasons a preferable,l

construction ina burner embodying the main features of my invention 1s illustrated in Figs. 3, 4, 5, 6, and 7. In this instance, the

burner consists of two separate parts-or castings I andJ, and is provided with an oiltrough D, a porous bed E, an airfchamber F, an oil-passage G, and 'amcombustion-chamber II, arranged and operating generally in the same manner as before setgforth. The oilpassage G in this case'ihs: formed by a passage` g, lextending longitudinally of the burner at the side of the latter adjacent to the opening lI and sloping fromV the `outer end of the burner downward to the .middle of the latter,

and a transverse passage g, sloping from the front towardtlierear of the burner and connecting such passage g with thetrough D. Two of said .passages g are preferably employed,extending from each end of the burner to the cross-passage g, so `that oil may be fed into the burner from either end thereof. The

.-cross-passage g in this instance `passes through the middle of the air-chamber F and divides the latter into two separate compart- The upper part or vcasting I of the,

ments. burner consists of a vertical wall of ring shape, and the top wall of the air-,heating `chamber F andthe passages g g g arefornied by aplate If, cast integral with the said upper part I and extending from end tovend of the latter. The bottoni part J of the burner consists, mainly, of a bottom plate J forming the lower walls of the passages g g and the bottom of the air-chamber F andthe trough D and having upon its side margins horizontal Hanges J2,which restupon thetop` "of the stove. The part I is fitted at its lower margins to the liange J2, the parts being secured together, as shown, by screws orbolts jj, passing through lugs t' upon the casting I and the ange J2. The bottom plate J is provided with parallel walls js js, which Ifare connected with the walls j2 j2, and which form,

together'with depending' ianges t" i upon the 4 top plate I', the cross-passage g. Vertical flanges l7"* jt, arranged longitudinally of the burner at either side ofl the `central passage g, form the inner walls of the trough D and separate the latter from the chamber Ff The end of the passage g adjacent to the troughQD is closed by av depending part Izof the plate I', which part reaches to a point near the bottom o f the trough, so as to leave a narrow slit or opening for the outfionr of oil from the passage g to the trough. Said part `I2 consists,ias shown, of vertical side walls i2,

forming eontinuations of the anges 'i'.and an end Wall t3, as .clearly illustrated in Figs. 4 and?. .At the endsof burner the castingI is provided with depending lianges I3 I3, ter.- minating somewhat above the bottom plate J', soas to form inlet-openings]L14 for the influxkof air to thechamber F. The passages g are closed at their ends by walls f, preferably cast upon the bottom plate J', and provided fwith holes j, through which an oilsupply pipe G maybe inserted. In a burner thus constructed it. is not necessary that atight joint. should be made between the oil-supplyipipeV and the oil-passage of the burner, and a pipe G' may be thrust loosely through the holes"`l7"` into either 4one of the passages g, and the oil dripping or iowing from the said pipe will run downward to the center of therburner and thence into the oil-trough- Dthrough the trans:

verse passage g. The passage Il for-the exit of4 the productsof `combustion frointhe burner downwardly into the stove is in this inst-ance formed between the flange jf., constituting the outer wall ofthe oil-passages` g g; and the adjacent portion of the,walll,gand

the heated products of combustion .pass over or against the vesselfor cover i1-pon: the. burner and the 4top of the lair-chamber., and .then

`downwardly through said passage Haz', So as to accomplish the heating A:of the walls of .the chamber and the air therein in the same manner as before described.

I have shown the castingliasprovided'witheV a mica-ecovered opening I4 in its.` part adjaj cent to the combustionchamber, whereby the condition of theiiame within the burnermay be observed without opening the,i latter.

' It maybe here remarked in connection with the form kof burners shown in. Figs. 1 to 7that said burners are more especially intended for burning lheavy oils or liquid hydrocarbons IOG IOS

IIO

having a relatively high flashing or Vaporizing point, and not for burning a light hydrocarbon, such as gasoline. It is not int-ended, therefore, in these burners that the oil shall become vaporized before reaching the point of combustion and thereafter burned in the form of vapor, but the oil supposed to flow in a heated state into the oil-trough and to be there consumed.

In Figs. S, 9, and lO is shown another form of burner, which is adapted for use in burning both oil and gas or vaporized hydrocarbons. This burner is generally similar to that illustrated in Figs. 1, 2, and 3, and embraces a 'casting M, provided with vertical side walls M', a bottom wall M2, a partial top wall M3, and a side wall M4, located inside of and parallel with the front outer wall of the burner, these several walls forming a combustionchamber Il, an air-heating chamber F, and an outlet-passage H for the downward passage' for theproducts of combustion to the smokeexit passage of the stove. At the side of the chamber F adjacent to the combustion-chamber is formed a longitudinal trough N, which trough is arranged over a longitudinal slot h, by which air from the chamber F passes into the combustion-chamher H. Anoil or gas supply pipe N is inserted through the end wallv of the burner and opens into the space of the air-chamber at aV point above the trough N. Upon the bottom wall M2 of the burner and extending beneath the trough N is an'oil-trough D, provided with a porous bed E, said trough D being used when oil is used as a fuel. A rib or flange m divides the trough D from the main part of the chamber F. Air is admitted to the air-chamber F at the ends of the burner through a tortuous passage f5, form ed in the casting M, as clearly shown in Figs. l, 2, and 3. In the use of this form of burner with oil, however, the oil delivered through the pipe 'N flows into the trough N and becomes distributed therein throughout the entire length thereof. When the trough has become lled, the oi-l overflows therefrom and drips into the trough D "and is burned at the top of the porous bed ftherein.

The trough N is preferably formed integral with the adjacent top wall'M3 of the chamber F, being connected with said top wall by a connecting part m', Fig. 8,Which forms one wall of the combustion-chamber, so

the burner is used for gas or vapor, the porous bed E is obviously not required.

Figs. 11, l2, and 13 show a burner embodying the mainfeatures of constructionpresent in the burners hereinbefore described, but differing therefrom in several particulars.` In

this instance the body of the burner consists of a single casting L, having side Walls and a partial bottom open at its top and made of the proper shape atits lower margin to fit the hole in the stove-top. The burner shown in Figs. l1 and l2 is made of oval form and adapted to fit over the large hole in a stovetop, while that shown in Fig. 13 is circular and adapted to be placed over one of the single round holes of a stove. The casting L is shown as provided with a rabbet 1 about the margins of its lower edge, fitting the rabbeted margins of the hole in the top plate, as clearly shown in the drawings. The open top of the casting L may be closed by the presence thereon of a vessel or cooking utensil, as indicated at K; but it may be provided with metal covers such as are commonly employed on stoves,and for this purpose its upper mar- 'gins are shown as made to correspond in size and shape with the hole in the stove to which the bottom of the burner is fitted, so that when the covers are removed from the stove they may be placed upon the top of the burner. In the bottom or lower part of the casting L, adjacent to one of its sides, isan oil-trough D, within which is a porous bed E. In the casting between the bottom of said trough D and the lower horizontal surface of the casting is formed a chamber or recess L', communicating with the said trough D by means of passages Z. An oil-supply pipe Gr communicates by passage Z2 with the interior of the said recess' L', whereby oil is fed to the said recess and to the trough D, which it enters by passing through the apertures Z Z. The recess L extends from end to end of the burner, is preferably arranged to occupy the entire space beneath the troughs D, and the oil is desirably fed to the central portion of said recess by extending the passage Z2 through a wall or partition Z3, reaching from the end of the casting to a point near the middle of the recess, as clearly shown in Fig. l2.

F indicates an air-heating chamber arranged longitudinallylof the burner near the middle of the latter and at one side of the trough D, said chamber being provided at one end with openingsff for the admission of air thereto, and having at its side adjacent to the trough D a longitudinal slot or opening Z4, by means of which air for supporting combustion passes from the airheating chamber to the combustion-chamber H, located over the oil-trough. The inlet air-openings ff to the chamber F are controlled by a damper, herein shown as consisting of a revolving plate O, apertured to correspond with the openingsfj', and provided with a handle 0, by which it may be turned. The opening Z4 may be, if desired, provided with a sliding plate Z5, whereby the size of the said opening may be increased or decreased, as found necessary or desirable for the proper working of the burner.

When the burner is placed upon thel stove and its top is closed by placing thereon avessel or suitable cover, the operation ofv the de- ICO IIO

vice is as follows: Oil supplied through the pipe G enters the chamber or passage L, the walls of which are kept at a high heat during the operation of the burner, so that saidy oil is heated before its passage into the trough D. Air for supporting combustion enters the chamber F, becomes heated therein,and then passes through the opening Z4 into the comupon the bottom surface of said casting, and

thereby greatly aid in the heating of said airchainber and of the part of the casting containing the said passage L.

The general construction described is the same either in the case of the long burner shown in Figs. l0 and 1l, or in that of the round burner illustrated in 4plan View, Fig. l2.

l I claim as my invention- 1. A burner consisting of a ring-shaped I casting or shell adapted to t at its lowerg utensils, a centrally-arranged air-heating chamber located within the said casting or shell, an oil-holding trough located between one side wall of the chamber and the shell, and the said chamber being provided with a'slot or opening for the admission of air from the chamber to the main trough, and the side Wall of the chamber opposite the said trough being constructed to constitute one side of an opening or passage leading downwardly through the shellor casting to the space between the stove upon which theburner is placed, substantially as described'.

2. A burner comprising a casting or shell provided at its top with a hole for cooking utensils, and with a bottom wall having an exit-opening at one side for products of combustion, a central air-chamber, ,an oil-holding trough located at the side of said airchamber opposite the exit-opening, and an oil-supply passage formed in and by the Walls ot said air -cha1nber, substantially as described.

In testimony that I claim the foregoing as my invention I aix my signature in presence of two Witnesses.
