I as

for automatically opening the valve when the radiator is inserted into the oven. The rear wall of the stove has a recess 39 for receiving this finger.

Mounted on the forward end of the radiator housing, is a plurality of horizontally disposed deflectors 40 which may be angularly adjustable if desired. The top and sides of the radiator housing have extensions 41 projecting beyond the deflectors.

Mounted on the sides of the radiator housably engage certain of the racks 121 for sup- The flanges 42 are preferably positioned so that the lower edges of the radiator walls 33 will slidably engage the oven bottom 11.

Mounted in the lower end of the radiator housing is a tube sheet 43 which is prefer-' ably of inverted cup shape to form a heater compartment 44 which is adapted to be placed directlyabove the burner, as shown in Figures l and 3.

The radiator also has a top header 45 which has an outlet pipe 46 projecting through the radiator top 32 for communication with the flue 19 through the opening 20. This header 45 is preferably spaced from the top 32 so as to permit the air stream to engage both faces of the header, thereby increasing the etlicieney of ther radiator.

Communication between the two headers is provided by a plurality of vertically disposed flues which are spaced apart to define air assages for the flow of air through the radlators. In the form shown in Figure 5, these fiues consist of pipes 47 which are "connected to the two headers.

In the preferred form shown in Figures 1, 2 and 3, the radiator has flues 48 of the same length and width as the side walls 33. These flues 48 are tapered rearwardly so as to define forwardly tapering air passages 49 between the flues. This type of core is highly efiicient.

In operation, when the stove is used for baking,'the radiator is removed from the oven, and the cover plate 15 is placed over the opening 14. Upon withdrawal of the radiator, the air valve 28 closes automatically.

When it is desired to use the stove as a heater, the plate 15 is removed and the radiator is inserted into the oven in the manner indicated. When the radiator is moved rearwardly, the cam 38 engages and lifts the valve arm 31. The burner is then ignited, and the fan is operated for forcing air forwardly.

through the radiator.

It will be understood that details of the constructions shown may be altered without de arting from the spirit of the invention as de ned by the following claims.

I claim:

1. A stove comprising an oven having a bottom plate provided with an opening, a burner compartment below said oven, a burner in said compartment below said opening, a flue above said oven, a removable radiator located in said oven above said opening and having flues providing communication between said burner compartment and said first mentioned flue, and a fan for causing a flow of air through said radiator.

2. A- bake oven having top, bottom, rear and side walls, a flue adjacent the top of said oven, said bottom wall having an opening, a burner adjacent said opening, a removable radiator located in said oven, said radiator comprising upper and lower headers and a plurality of intermediate flues, said lower header communicating with said opening, said upper header communicating with said oven flue, and means for causing a flow of air through said radiator.

3. A bake oven having top, bottom, rear and side walls, a flue adjacent the top of said oven, said bottom wall having an opening, a burner adjacent said opening, a removable radiator located in said oven, said radiator comprising upper and lower headers and a plurality of intermediate flues, said lower header communicating with said opening,

said u per header communicating with said oven ue, said radiator flues being spaced apart to define air passages, and a fan for causing a flow of air through said air passa es.

4. stove comprising an oven having a rear wall provided with an air port, a valve adapted to normally close said port, a portable radiator removably mounted in said oven, said radiator having a part adapted to engage and open said valve, and a fan mounted adjacent said port for forcing air through said radiator.

5. A stove comprising an oven having a rear Wall provided with an air port, a valve normally movable into position to close said port, a portable radiator removably mounted JESSE L. BRIGHT.
