The present "invention provides an improved stove that -is "arranged for cookingand baking and-wlth the embodiment ofcertain fea- -tures and arrangement "oi constructiom-the room or enclosure in 'w-hich the-' stovelslocated is effectively illuminated.

The fuelfor the stove maybe a" suitable oil, manufactured or natural. gas, or electricity.

"The outstanding advantage *of the invention .is the fact that due to. the scientifically-arranged combination of three sources *of ut1lity;-namely heating, cookingand lighting,- the invention pre- "sents a new era and transformation from an economical viewpoint-,jnthis particular field of industry.

. Further readily apparent during coming detailed description,

advantages "of the invention will. be

the course of the forththroughout-the acis located directly under the respective burners An oil drip pan I6 is employed for each -of said burners and is secured thereto as shown in Figure 9. A door I1 is arranged for each of said fuel chambers and each door being mounted on hinges, and having a suitable door handle I9;

said doors being adapted to close the openings in the'respective chambers in a substantially tight "manner. A plurality of elongated windows .are provided in each of doors H and are closed with heat-proof transparent material.

' Referring more particularly to Figures 8 and 9 it is observed that a double baffle member 2| is provided with its underside forming the ceiling of fuel chambers I; said member being preferably a suitable hollow casting, provided with openings within the top portion thereof which are adapted toreceive stove lids 22 where indicated. There 'companying illustrative drawings, and'more particularly pointed-out'in the {appended claims.

Figure 9 is a-longitudinal section takenupon line 9+9 of Figure 3.

Figure 10 is acompletefiviewof the bottom of the device and showing the underai-r draught control.

The invention comprises a metal casing :or :enclosure having front panel 'side panels 2, rear panel- 3, top" 4 and bottom 5, and with-legs formed as at 6.

Fuel chambers l arerormed by a=bottomwall 5, rear wall 8, side walls 9 and a common partition Ill, forming thereby two independent chambers. Within said chambers suitable burners II are positioned as shown in Figures 8 and 9, with fuel supply lines |2 for the respective burners, being provided.

Within bottom 5 openings l3 are provided so as to accommodate under air draught levers I4, said levers being pivotally secured to bottom 5 as at l5, and it is seen that said under draught is an opening 23 in the underside of baffie member 2| directly over the burner in each of the --fuel chambers I, and in axial alignment with -the cor-responding lid opening, so that the heat from the burners will directly contact said lids.

A spacious oven 24 is provided with a suitable -door25, having pulls 26 therefor as shown. The door being pivotally connected to members 21,

which are adapted to slide upon rails 28 within "the top portion of the device when said door is --opened, as indicated by the dotted lines in Figure 8.

An opening 29 is arranged in door and is closed by a suitable transparent heat-proof -material. The oven is provided with a curved --metal back 30, which extends to a point ad- --jacentthe bottom of the casing with its lower portion formed as shown at 3|. The inner surface back 30 and the portion 3| thereof are pro- -vided with a high polish and mirror finish from reflecting surfaces.

Refiectors'32 and 33 are also provided in vertically spaced cooperative relationship on each of the side walls of the casing; the reflectors 33 --'the fuel chambers and the reflectors 32 being opposite the windows 4|] in the upper side walls of the casing which have their inner surfaces being opposite the windows in the side walls of v Referring to Figures 5, 8 and 9, a screened grate 35 is provided and is removably positioned within oven 24 as indicated; Said grate may be readily removed for cleaning purposes. The oven chamber is formed by the back Wall 30, the top of the bafiie member 2| and side walls 36.

The fumes and objectionable gases are discharged from the interior of double baiile member 2| by means of pipe 31, which leads to the house chimney A, as indicated in Figure 8. In Figure 4 pipe 37 is shown as having a funnel shaped end as at 33 communicating with both divisions of the interior of double baiile member 2! so that combustion gases are simultaneously discharged from such compartments.

In Figure 10 it is seen that bottom 5 of the device is substantially braced to side panels 2 and rear panel 3 by means of braces 33 as indicated.

An opening 43 is provided in each of the side panels 2 at points directly above the reflectors 33. Openings 41 are provided in the rear and side walls of the fuel chambers 7 directly opposite the reflectors 3i and 33 and are covered with heat-proof transparent material.

For baking purposes door is pivotally elevated by means of knobs 26 thereon and is slidably moved inwardly upon rails 28, as clearly shown by the dotted lines in Figure 8, the utensils with the baking material are then placed upon removable grate 35, and the oven door accordingly closed. In Figure 9 it is clearly indicated by the arrows, how the intensified heat from burners II is baflied by reason of the lower portion of bafile member 2| and said member having upper and lower walls provide a bailiing chamber for each of fuel chambers I through openings 23 within the lower walls of said member. An opening or window 29 within door 25 affords adequate facility for viewing the baking within oven 24 admitting of the proper attention required.

While oven 24 is entirely enclosed there will be suflicient heat within the upper portion of the stove to provide for ordinary cooking, and for this purpose the elongated openings 42 are arranged within top 4, as clearly indicated in Figure 3.

It is understood that the design and exterior finish of the stove is very attractive, and may be placed within the parlor, or in fact within any suitable location of the dwelling, and by virtue of door 25 being adapted to open as previously explained, and when in an opened position as shown by the dotted lines in Figure 8, and by reason of the curved back 328 of the oven, the stove becomes an attractive radiant heater.

Referring to Figure 9, the heat from burners I I will radiate through flue passages 43 and out through opening 45 within each of side panels 2, as shown by the arrows in this view, consequently it is understood that the device provides a very effective heating unit that is capable of heating an entire dwelling consistent with space to be heated and the proportional size of the stove used. The heat is greatly intensified by virtue of reflectors 32 and 33 and back 33.

An additional advantage and a novel feature of the invention is the illuminating qualities it reflected into the room.

possesses. This is accomplished by means of windows 4| that are located within the respective walls of fuel chambers 1, and again referring to Figure 9 the arrows therein indicate how the light from burners ll passes through said windows and simultaneously upon reflectors 3| and 33, and the reflection of said light upon reflector 3! will in turn be reflected to back as indicated by the arrows in Figure 8, and when door 25 of oven 24 is closed the last-named light rays will pass out into the room through window 29 within said door. When door 25 is opened then the entire benefit of reflector back 30 is obtained for light into the room.

The light rays through windows 4| from bumers I I upon reflectors 33 will in turn be reflected 'upon'reflectors 32 by virtue of uninterrupted flue passages 43, thence outwardly through openings 48 within side panels 2 and into the room. Thus it is understood that the same elements and arrangement thereof effect a combination for the scientific result of both heating and lighting for the intended purpose. It is to be finally understood that the lighting effect of the invention would be confined to the room in which it is to: form therebetween air heating passages; a win-r dow in the rear wall and in one of the side walls of each of said fuel burning chambers; a window in each side wall and in the front wall of said casing and vertically spaced above said firstnamed windows; and a reflector positioned oppo-' site each window; the reflectors opposite the casing windows cooperating with those opposite the fuel burning chambers to reflect the light rays therefrom into the room.

2. In a combined cooking and heating stove, an outer casing; means within the lower portion of said casing forming a fuel burning chamber spaced from the rear and side walls of said casing to form therebetween air heating passages; means within the upper portion of said chamber forming an oven spaced from the rear and side walls of said casing to form therewith continuous of said air passages and including a curved back wall which extends downwardly below and in spaced relation to the rear wall of said fuel cham-' ber and having a reflecting surface in the oven and opposite the fuel chamber whereby light rays from the latter will be reflected toward the front of said oven; a window in the rear wall of said fuel chamber opposite the reflector in said back wall and in each sidewall, a window in each side wall of the casing and cooperating reflectors positioned opposite the windows in said side walls whereby light rays from the fuel chamber will be J GEN H.
