Application filed August 23, 1922. Serial No. 583,783. it

To all whom it may concern:

Be it known that I, 'JosnrH S. HELTON, a citizen of the United b'tates, residing at Perry, in the county of Noble, State of Oklahoma, haveinvented certain new and useful Improvements in Cookstoves, of which the following is a description, reference'being had to the accompanying drawing, and to the figures of reference marked thereon.

My invention relates to new and useful improvements in cook stoves.

The object of my invention is to provide a stove of this character, in which there are two spaced ovens, one above the other, with passages for the products of combustion leading from the fire box to the smoke flue, so arrangedthat said products of combustion may be caused to travel over the upper oven and under the lower oven or partially over and under the upper oven, or under the upper ove'n'and over the top and under the bottom of the lower oven, so that the desired heat at the proper point may be obi opposite to' which is attached the smoke pipe tained in either one of the ovens. Anotherobject of my invention is to pro videa' stove of this character, in'which a water-back is arranged and a tank, said tank serving as a warming shelf, and at the same time provides a compact stove in which all of the heat from the products of combustion is utilized for heating'the water and the ovens before it passes to the smoke flue.

Another object of my invention is to provide a simple, cheap and effective stove, which may be made either of cast or sheet metal, and having certain details of structure and combination of parts hereinafter morefully pointed out and described.

In the accompanying drawings Figure lis a front elevation of my improved stove;

Fig. 2 is a top plan view of Fig. 1;

Fig. 3 is a longitudinal vertical sectional view taken on the line 3.3 Fig. 2;

tion of the arrow Fig. 1; and

Fig. 5. is a sectional view of one doorshowing the door supporting arm for'hold ing thedoor'in a horizontal position when open.

Referring now to the drawings, 1 represents a rectangular casingeither of sheet metal riveted together, or cast: and secured together in any desired manner, and supported by feet or legs 2. The upper face or serves as one wall of the same.

top 3 of the stove is made solid with the exception of the single opening i, closed by a lid 5, and by means of which the fuel is fed to the fuel box or fire box. Supported in the left hand side of the casing or stove is a water-back 6, which may be made as a separate tank or receptacle, or may be made by a partition extending from the top 3 ofthe stoveto the partition 7 in which event the end of the stove casing As this particular way of forming the water-back does not form the essential feature of my invention, its'detail construction will not be further' described.

Asheretofore stated, the stove, adjacent the bottom 9, is provided withthe partition which extends'fromthe left handend of the stove to a-ypoint a short distance from the right-hand end '10, 'and said partition like Wise extendsfrom t-he'front wall 11 to the rear wall '12 of the stove, having therebelow a horizontal flue 13"whichcommunicates-at the left of the stove with an openi'ng 14:,

15, which. leads upwardly along side the end of the stove and serves as an' additional means ofsupplying'heat to the water back 6, as clearly shown in Fig. 30f the drawings. The smoke pipe is provided with a damper 15 for regulatingjthe draft. In Fig. 3, the top of the smoke pipe 15 is illustrated as provided with an extension for carrying oii' the smoke and other products of combustion.

Arranged vertically along side the water back 6 is a thickened plate which may be of cast metal, orfire brick, and is adapted to protect the thin wall of the water-back from the direct heat of the fire box, as" shown in Fig. 3 of the drawings. A vertical partition' 17 extends from the longitudinal partition 7 to a point 18, below'the top 3 of the stove, leaving the horizontal passage 19 from the firebox 2 0, to allow the products I of combustion to pass therefrom; The fire Fig. 4 is an end View looklng 1n the d recbox 20 has'a grate 21 of any desired form therein and opposite this fire box is a door 22, which opens atthe front of the stoveso that access may be had to'the fire box. Below the door 22 is a door 23 which gives the proper draft to the fire box below the grate. Below the door 23is the ash door-24E; which is of a size to allow the ash'pan 25 to be removed therefrom, all of which is readily understood and needs no further description.

Thepartition forms the bottom of the lower oven 26 and does not extend to theend 10 of the stove, but leaves the vertical passage 27 at the right, as shown in Fig. 3, and communicates with the horizontal flue 28 and extends from the end 10 to the partition 17. The oven 26 extends from the rear wall 12 of the stove through the front wall and is closed by the door 29. Arranged above the oven 26 is an oven 30, having a flue 31 at one end adjacent the partition 17, the flue 28 below, the flue 32 at the other end and a flue above. The said flue 33, as shown in Fig. 3 of the drawings, communicates at the left with the opening 19, in the upper end of the fire box 20. Arranged in the flue 33 is a damper 34, so constructed that the products of combustion passing from the opening 19 in the fire box may be diverted into the vertical passage 31 or the horizontal passage 33, or arranged in a horizontal position so that part of the products of combustion will pass into the passage 33 and some into the passage 31, as will be hereinafter more fully described.

The end 12 of the stove casing is provided with openings 35, 36 and 37 arranged opposite the horizontal flues 13, 28 and 33, whereby access may be had for cleaning out soot therefrom. These openings are closed by caps or plates 38, 39 and 40, all of which is fully shown in Fig. 3 of the drawings. The damper 34 is provided with a crank 41 which extends out through the front of the stove, so that it may be turned, as shown in Fig. 4 of the drawings.

The top 3 of the stove has a plate 42 arranged above the fire box 20 to protect the thin top late 3 of the stove against the direct heat fiom the products of combustion, and this plate may be ofcast metal or fire clay. The oven 30 extends from the rear wall 12 of the casing through the front wall and is closed by the door 43. The doors 29 and 43 are hinged at their lower ends by means of the hinges 44, and are provided with the plates 45 adapted to engage the outer face of the front of the stove and support the doors in a longitudinal position when open, as shown in Fig. 5 of the drawings.

Carried by the rear wall 12 of the casing are brackets 46, supporting a rectangular tank 47 which extends the entire length of the stove and some distance above the top 3. The upper end of the tank, at the rear, is provided with a plate 48, whereby the tank forms a warming shelf at the rear of the stove.

Extending through the end of the stove is a pipe 49 which communicates with the upper end of the water-back 6 and extends upwardly and communicates with the upper end of the water tank 47. "A pipe 50 ex tends through the end of the stove and communicates with the lower end of the water-back and is connected to the tank adjacent the lower end. By this arrangement, it will be seen that a circulation of the water from the water-back 6 into the tank 47 and back is caused, thus heating the water in the tank. A water supply pipe 51 is connected to the water-back through the rear wall of the stove and a water discharge pipe 52 connected to the tank47 adjacent its upper end.

From the foregoing description, it will be seen that, by providing the two ovens and the arrangement of the flues for the products of combustion, the heat may be directed to the ovens at the desired points. By arranging the damper 34, as shown in full lines in Fig. 3, the upper oven does not receive any direct heat at the top, but the products of combustion will pass through the flue 31 along the flue 28, heating the bottom of the oven 30 and the top of the oven 26, and down the flue 27 into the fine 13, so that the end and bottom of the oven 26 is heated and gives the oven-26 a uniform heat on three sides. If the damper 34 is turned as in full lines of Fig. the products of combustion pass to the flue 31, down the flue 31, and through flue 28 and flue 27 and out the flue 13, so that only the top and bottom of the oven 26 is heated. If the damper 34 is arranged horizontally, as shown in dotted lines in Fig. 3, a portion of the products of combustion will pass into the flue 33 and a portion into the flue 31, and both ovens are heated above and below. This arrangement has been found essential in baking different kinds of foods as some require heat above and others below, and some re quire the same heat above and below.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is:

1. A stove comprising a casing, a waterback at one end, a fire-box adjoining said water-back to heat the same, an oven in said casing having flues surrounding the same and receiving the products of combustion from the fire box and discharging them below and along the opposite side of the water back.

2. A stove comprising a rectangular cascasing and extending from the top to a point adjacent the bottom, a fire box adjoining said water back and having its lower end in a plane with the lower end of the water back, two ovens in said casing and spaced apart and having flues therearound adapted to allow the products of combustion to pass from the fire box around the ovens and discharge from the casing below the water back and fire box.

4. A. stove comprising a rectangular casing, a water-back in one end of the casing, a fire box beside the water back, an oven in the casing having flues on four sides, a second oven spaced from the first oven and having fiues on three sides, and a damper controlling the passage of the products of combination in the flues and discharging them from the casing below the fire box and the water-back. ,7

5. A stove comprising a rectangular casing, a water-back in one end of the casing and extending to a point a short distance above the bottom of the casing, a fire box having its lower end in a plane with the lower end of the water-back, an ovenlin the casing and having fines above and below and at each end, a door closing the front end of the oven, a second oven spaced from the first oven and extending from the fire box to a point adjacent the end of the casing and from the bottom of the casing, a door closing the front of the oven, said casing having openings opposite the three horizontal fiues above, between and below the ovens, a damper adapted to control the products of combustion to direct it above or below the upper oven or partially above and below, and said products of combustion discharged from the casing below the fire box and water back, and a smoke fiue extending up the sbidekof the casing and abutting the water- In testimony whereof, I afiix my signature. 7
