STOVE.

Application filed. August28, 1922. Serial No. 584,676.

My invention relates to improvements in cook stoves and more particularly to that class known as combination coal and gas stoves.

The object of my invention is to provide an improved combination coal and gas stove equipped with an oven adapted to receive heat from either the coal burning portion of the stove or from the gasburners. A further object of my invention is to provide a stove as mentioned equipped with means for heating water in a boiler for domestic purposes, so arranged that the water will be heated either by the coal burning portion of the stove, by the oven heating burners, or both. A further object of my invention is to provide a stove as mentioned which, in cold weather, when coal is used, will serve as a heating stove for heating the room or a small suite of rooms. A further object of my invention is to provide a stove of the class mentioned whichshall be of neat and ornamental appearance. Other objects will appear hereinafter.

.With these objects in view my invention consists generally in a stove comprising. a coal burning portion of the general type known as base-burners., an ovenarranged at the side of the body portion thereof and receiving heat directly therefrom, and a gas burner for heating said oven. My invention further consists in a deviceas mentioned,-

in whichthe stove top comprises two vertically spaced rectangular members, the lower member consisting of a flatplate constituting the top of the oven and extending around the upper end of the body of the baseburn ing portion, and an upper m'emberconsti- 'tuting a grid to receive the ordinary stove lids over the coal burning portion, and the usual spiders over the oven portion, there being gas burners arranged beneath the latter, and a vertical partition between said members spacing the coal burning portion from the gas burning portion. My invention further consists in a device as mentioned in 'combinatlon with a water 0011 or acket surrounding the fire pot of the base-burner, a'

coil arranged within said oven, a burner .ar-

ranged beneath said coil, and circulating pipes connecting said coils and affording means for connecting the. same to the domestic water boiler. My invention further consists in various details of constructions-and arrangements of parts all as will be fully dei beside the body and attached to thewall 4t.

scribed hereinafter and out in the claims. a

My invention will be more readily under stood by reference to the accompanying drawings forming a part of this specification and in 'which Fig. lis a front elevation of a stove embodylng my invention in its preferred form, Fig. 2 is a horizontal section on the line 22 of Fig. 1, portions being broken away and one of the lids removed, Fig. 3 is a horizontal section on the line 33 of Fig. 1,

Fig. 4 is a detail line 4-4 of Fig. 2,

Fig. 5 is a detail rear elevation, and Fig. 6 is a detailsection on the line 6 6 of Fig. 2. i p I i Referring now to the drawings, the coal burning portion of the stove comprises a fire pot l resting upon'an ash box 2 supported by legs 3. These portions are preferably of cast iron. Resting upon the fire pot portion 1 is abody 4, preferably circular in crosssection. These. portions ofthe device are similar to the ordinary'base-burner stove. The ashbox 2 is provided with the usual draft and clean-out door 5 and the body is providedwith the usual door 6. Arranged vertical section on the coextensive in height with'said body portion and provided witha door 8 whichmay be supported in any preferredmanner, as by hinges 9. The walls of the body portion l are unlined and are preferably of sheet iron and the adjacent wall of the oven 7 is bent outwardly. as indicated at 10 (see Fig. 3) It will thus be seen that the portion of the wall 4 of the coal burning portion, between thewalls 10 forms a portion of the oven wall and the oven will receive heat radiated directly from this section of the wall of the coal burning section of the stove. 11, 11 indicate racks for adjustably supporting the oven slide or shelf 12. A gas burner 13 is arranged beneath the oven 7 and a burner 14 is arranged within the upper portion of theoven, affording meansfor heating the oven by gas. The side of theoven remote from the coal burning portion of the stove is supported bylegs 15.

The top of the stove comprises two rec-' tangular. horizontal members 16 and 17, the

latter being arranged above the former and 4.- is an oven 7 substantially .tiSSIG-IV'OIRI TO JAMES particularly pointed ofv the body portion spaced therefrom peripheral walls 18, 1 9 and 20. A vertical wall 21 extends from the front to the back of the top between the members 16 and 17 and spaces the portionv ordinary stove lids 26, over. the coal burning portion, and the spiders 27 over the oven, gas burners 28 being arranged beneath the latter between the members 16and 17. It is obvious that the arrangement may be such as to provide for any number plates ofspiders, this being dependent entirely upon the size and relative proportions of the several parts. p

The fire pot 1 is formed with a water coil or jacket 29 from which extend pipes 30 for connecting the same to a domestic water boiler. Arranged in. a housing31 preferably in the bottom of theoven and over the burner 13 is a water coil 32 which is connected by pipes 33 with the pipes leading from thecoil 29. It will thusbe seen that the coils. 29 and 32 are connected and are providedwith means for attaching the same to a domestic water boiler. By this arrangement, the; waterin the boiler will be heated whenever the oven is heated either 'by ,the coal fire or from the gas burner. It will be further noted that when the oven is heated from the coal burning portion, that both coils will be heated. Thisis of particular advantage as, in winter time, when the most hot water is usually needed, the water will be more rapidly heated, in that both coils will be heatedsimultaneously. 4 V y The stove is'provided with a back 34 extending upwardly frornthe rear portion and provided at the top with warming chambers 35 which may or may not be provided with doors. As illustrated in the drawings, I have illustrated one chamber provided with a door 36 and the other chamber without a door.. 37 indicates side brackets supporting the chambers which may be of any preferred orm.

Arranged beneath one of the openings which is normally closed one of thefront lids 26, I provide a coal chute for directing the coal througlrthe open ng 22 and to preventthe same from accumulatlng between the members 16 and 17. This preterably comprises an inclined, curved sheet metal memberQS supported at its lateral edges by brackets 39. The brackets 39 are provided with upwardly extending flanges -10 forming sides to the chute. This construction provides a simple device for directing the coal into the stove and preventing the same from accumulating between the members 16 and 17; and at the same time permits heat to circulate freely to uniformly heat. the top of the stove between the walls 19 and 21. This construction is clear- 1y shown in Figs. 2 and 6 ofthe drawings.

It is obvious that the stove as ziblovedescribed will be efiicient as a coal burning stove for use in winter or as a gas burningstove in warm weather. The construction of the coal burning portion is such that when the same is used in cold weather, it not only serves as cook stove but isextreinely efficient to heating the kitchen or a small suite of rooms. A large portion of the shell of this portion of the stove will radiate heat a into the rooms, while an ample p'ortio n-that between the walls 10 10, will afford sutii cient heat for heating the oven. Furthermore, the stove is of such a neat and ornamental .appearance that it will greatly add to the furnished appearance or; the room where used. In regard .tothe means forheatingthe water for the domestic boiler, it will be noted that in the summer time, when gas is used, the water may be heated by means of the burner 13. In winter, when more hot water is usually required, both coilswill be heated from the coal burning portion. It is 'obvious that the coils 29 will receive heat directly tronrthe fire in the fire pot; and as the oven is heated from the base-burner portion, andthe coil 32 is. arranged withinthe stove, this latter coil will also be heated from the coal burning portion. I claimv I v 1. In a stove,' a coal-burning portion of the base-burner type having a fire pot in which coal is burned and an unlined sheet metal body of the same cross-sectional shape as the firepotand rising from the walls thereof, a chambered top portion supported on the body portion, anda flue leading from said chamber, whereby the products of combustion from the coal pass up through the body portion and the chamber of the top portion directly to the fine, in combination with an oven arranged beside the unlined sheet metal body and at a higher levelthan the fire pot,j the walls of the oven joining said body on opposite. sides thereof and the portion of the unlined wall of the body between thepoints where the oven wall meets the body constituting a portion of the wall of the. oven,avh ereby when coal is being burned in the base burner the oven is heated solely by transference of heat through said portion of the unlined wall o'f the body, and gas burners arranged for heating said oven independently ofthe coalburning portion. I

2'. In a cook stove, a coal burning portion of the base burner type, an oven arranged beside the same and receiving heat directly therefrom, a gas burner for heating said oven independently of said coal burning aortion and a top for said. stove comprising a pair of horizontal rectangular members, spaced one above the other, the lowermost member comprising a flat plate constituting the top of the oven and having an opening above and substantially commensurate with the upper end of said coal burning portion, the upper member comprising a grid for the usual stove lids above the coal burning portion and with spiders above oven, and gas burners arranged beneath said spiders, substantially as described.

3. A device as set forth in claim 2 further characterized by walls connecting the upper and lower members of the top and dividing the space between the same over the coal burning portion from that over the oven, substantially as described.

4. In a stove, a coal-burning portion of the base-burner type having a fire pot which has a Water coil integral therewith, an unlined sheet metal body of the same crosssectional shape as the fire pot and rising from the walls thereof, a chambered top portion supported on said body and a flue communicating with the chamber of the top portion, whereby the products of combustion from the coal burning in the tire pot pass through the body and chamber of the top portion directly to the flue, in combination with an oven arranged beside the body and at a higher level than the fire pot, a portion of the unlined wall of the body forming a portion of the wall of the oven whereby when coal is being burned the oven will be heated thereby solely by heat transference through said portion of the unlined wall, a waterheating coil in the oven, pipes connecting the water coil in the oven to the water coil on the base-burner, and means for heating the oven and the Water coils therein independently of the coal-burning portion.

In testimony whereof I have signed my name to this specification. 1
