Seriallim299fl65a This invention relatesto a-combined incinerator and waterheaterand is acontinuation vide a combinedincineratorzand water heater ofsuch a character-that insubstantial-portion of the. Water heating surfaces will be so arranged that the products of combustion" of "II the'material being consumedfiwill'notcome in contact therewith and consequently such .surfaces wilt not: become :coated with; grease '01 other matter given. oil by! the material which is being consumed: v

A' further object'of the invention is: toprovide such an apparatus with a receptacle for the material to be consumed of such-a character that. the lower portion thereof, which "is subjected tothe greatest heat, maybe renewed when Worn out Without discarding the receptacle as a Whole.

A further object ofthe invention is to provide a combined incinerator'and waterheater having amain burner provided with; inner and outer gas outlets to direct the flame against the bottomofthevreceptaele for-the material to be consumediand against'the-tank and having associated" therewith a pilot burner of such acharacter that it will simultaneously ignite the gas' at both the inner and outer outlets ofthe main burner.

In these drawings I have illustrated one embodiment. of my, invention together with a slightly modified form ,thereof but it will be understood .thatthese embodiments have been chosen for thezpurposesof. illustration only andE that the apparatus may takevarious forms-without;departing from the, spirit of the invention.

In that form illustrated inF-igs 1 and 2, the apparatus?comprises aztank lwhieh is annular in form and has; an inner circumferential wall Zand an outer circumferential Wall. 3, the inner and :outer Walls beingconnectedat their; upper and lower ends respectively. by a top Wall 4 and a bottom Wall 5. The outer circumferentialliwall (proj ects some distance below-thebot'tom walla and ,isprovided with an inwardlybextending annular. flange or subbottom 6 having; acentral :openingto receive at burner 7. The tank is preferably supported-0n legs :8 or similar supports so that the burnerissome distanceabovethe floor. Depending; from the sub-bottom 6, about the opening therein, is a housing 9 having inwardlyfextending brackets 10 on which the burneri 7 is supported. This housing also has a flange 11 which cooperates with a;latch(12 toremovably support anash pan 13.

Means are providedgfor supporting the material to, be consumed Within the central opening. to the tanln This means may, take various forms, and may be wholly separate fromw the tank or it may utilize a portion of the tank in the supportingfunction. As here shown; asupporting structure is mounted on the upper end ofuthe tank and consists of a ring or annular casting 14 secured tothe tank: aboutthe upper end of the opening and Comprising an inwardly extending portion 1-5-spaced frointhe top Wall 4 of the tankand provided with an upwardly extendingflange 16; Supported upon the inwardly extending portion 15 of the casting 14 and about the-flange 16 is a housing 17, preferably cylindrical in form and having at its upper end an inwardly extending flange 18. Arrangedwithin the opening inithe tank is a; hopper 19 Which is preferably supported wholly at its upper end upon the supporting structure consisting of the casting let and the housing 17. To this end a ring. 20 is rigidly secured to the upper end of the hopper and has an outwardly extending portion which overlaps and issupported by the flange 18 of the housing, the two parts having contacting surfaces arranged to form a tight JOlIlt. Thus the hopper is supported wholly upon the housing and can be removed from the tank by merely lifting the same there from. A cover 21 ishinged to the ringr20 V of the hopper to close the upper end thereof and prevent the escape of fumes; The hopper is, in the present instance, of a diameter 'somewhatless than the diameter of the opening through the tank, thereby providing between thehopper and the tank a passageway 22. The lower portion of the hopper is perforated and, in the present instance, the circumferential wallthereof is provided with slots 23 and the bottom wall 24: is slotted. As here shown,ithis bottom wall is in the form of a grate, the inner portion 25 of which is movable to facilitate the removal of ashes from the hopper. In'the present construc-v "tion, the bottom wall is flanged to embrace the lower end of the cylindrical wall of the hopper and is detachably secured thereto by boltsor screws 26, thus enabling the bottom wall to be removed and renewed if necessary. e

I also prefer to so construct the hopper that thelower portion thereof, which is subjected to the greatest heat, may be removed and renewed independently of the'upper portion.

:To this end the hopper is formed in two parts, the upper portion being removably supported on the tank and the'low'er portion,

shown at 27, having lugs 28 overlapping the lower end of the upper portion and secured theretoby boltsi29. Preferably the upper endof the hopper is flared, as shown at 30, to facilitate the introduction of the garbage or-other material into the same and the upper end of the inner wall of the tank is flared, as shown at 31, to maintain the proper spacing between the same-and the flared por- .tion of the hopper. The space or passageway 22' opens into the interior of thesupporting 'structure,which constitutes an outlet passageway or chamber for the products of combust-ion and: is provided with an outlet 32 adapted to. be connected with a flue. The upper end of the hopper, which extends into i this outlet chamber, is slotted, as shown at 33,

to permit the fumes and'gases to pass from the hopper to the outlet 32. As here shown, the flared upper'end of the hopper is flat on that side adjacent to the outlet 32, as shown at 34, to avoid restricting the capacity of the outlet.

f. The productsof combustion both from the burner7 and from the material'which is being consumed will act upon the inner through the body of water in the'tank. As

here shown, these other passageways consist of conduits ortubes 35 mounted in the upper and lower walls of the tank a short distance from the inner wall 2 and spaced apart about that inner wall. Thus the lower ends ofthe tubes or passageways are so arranged that they will receive the products of combustion from the burner 7 but, being in the bottom wall of the tank, they will not receive any of the greasy gases or other prodf nets of combustion from the material which is being consumed within the hopper and consequently they will" not become coated with such greases or other materials, whlch coating would tend to restrict the passage of heat through the same to the water. These passageways 35 open into the annuflar portion of the outlet chamber, formed between the portion 15 of the casing 14 and the top wall of the tank, so that all prod-' nets of combustion are delivered to the outlet chamber. The portion 15 overlaps the upper ends of the passageways 35 and being spaced but a short distance therefrom tends to retardthe flow of'the products'of combustion through these passageways and thus maintain the same fora longer time in contact with the walls ofthe passageways, causing more of the heat thereof to be'taken up v by the water. 7

The burner 7 which is shown in detail in Figs. 3 and 4c is preferably annular .in form and ;is provided with inner and'outer gas outlets so arranged that the flame from the inner outlet will be directed against the bottom of the hopper and the flame of the outer outlet will be directed against the bottom of the tank andcthro'ugh the passageways 22 and35. As here shown, theburner comprises a lower portion 36 and an upper portion 37 spaced from the lower portion to provide slots 38 and 39 atthe inner and outer edges, respectively, of the burner. The upper portion also has inwardly and outwardly projecting portions 40 and 41 overhanging the slots to prevent the entrance of foreign matter to the burner. The burner 7 ispreferably automatically controlled by means of a thermostat in "the tank or elsewhere. This method of control being well known and forming no part of the present invention is nothereshown. .Because. of the character of the burner, it is necessary that the pilot burnershall'be of such a character as'toinstantly ignite-the gas at both new? th'e'inner and-outer" outletsof' the burner and for this purpose Ilhave provided a': special pilot burner. Preferably this pilot burner is arranged above the annular burner' and hasgasoutlets directed respectively toward the inner and outer sides of the annular burner, it being understood that the gas from these outlets burns continuously. In the present construction the pilot burner is in the form of a housing 42 mounted on the top wall 37 of the burner 7 and connected thereto by a supply pipe 43 which extends through the two parts of the burner 7. At the upper end of the supply pipe the housing 42 is provided with oppositely directed gas outlets or jets 44 directed respectively toward the inner and outer sides of the annular burner, the housing 42 having lateral openings 45 to permit the passage of the gas. Thus it will be apparent that when the pilot burner is ignited it will project a jet of flame above both the inner and outer gas outlets of the annular burner and when the gas valve is opened the gas will be ignited instantly on both sides of the burner.

That form of the apparatus shown in Figs. 5 and 6 is substantially similar to the form above deseribwl with the exception that it employs a slightly ditterent means for supporting the material to be consumed and has the passageways through the tank arranged in a slightly dilterent manner. As

here shown, it comprises a tank 46 having an outer wall 47 and an inner wall consisting of an upper portion 48 and a lower portion 49, the lower portion being of a diameter substantially greater than the upper portion.

.Thus the inner wall provides an opening through the tank which is of less diameter at its upper end than it is at its lower end. The smaller upper portion 48 of the inner wall utilized in part to supportthe material to be consumed and, as here shown, it extends slightly below the upper end of the laro'er part 49 of the inner we. 1, as shown at 00, and has detachably secured thereto a receptacle or basket 51 which is apertured in its bottom and circumferential walls and is arranged directly above the burner 52,

a which is arran ged below the opening through the tank. A supporting structure or top casting 53 is supported on the upper end of the tank and a short ho per 54 is supported on this casting and extends into the upper portion of the opening through the tank to guide the material into the receptacle. This supporting structure is hollow and of a greater diameter than the hopper 54 and constitutes an outlet chamber for the products of combustion, the hopper 54 being slotted, as shown at 55, to permit the products of combustion to pass through. the outlet chamber to an outlet 56. Passageways are provided to carry the products of combustion understood that I do. not. dcsire-to-be limited to-t-he details-theme various modifications may occur to" a. person skilled in I the art.
