Claims. (01. 21937) This invention relates to an improvement in portions thereof. Formed in each side wall 12 a collapsible electric stove, and has for its priare slots 30. mary object to provide a stove adapted for easy When the stove is set up the slots receive transportation when collapsed or knocked down, the tongues 17 formed in the flanges 16 of the 5 and adapted when set up to be used for cooking top plate 10. The side walls are thus held sewhether the heat be applied above or below the curely in place and the contact of the flanges food, as for example, for boiling, frying, bak- 29 with the top and bottom plates, see Figs. 1 ing, toasting, broiling, and the like. and 2, prevent any shifting or swaying of the Other objects of the invention will appear stove when in use. Preferably, as shown in Fig.

The stove is 15 tion ready for use; now connected to a source of current by means Fig. 2 is an enlarged sectional view along the not shown and is ready for use.

The side walls each terminate at a'bottom plate having flanges at opposite ends a; the ends in flanges 29 at right angles to the body thereof, and side walls having flanges at opposite ends thereof, said side wall flanges, when the stove is set up, bearing against the top and bottom plates and being confined by the flanges of such plates, the flanges of one of said plates having tongues projecting therefrom and the side walls having slots therein which receive such tongues to secure the side walls to the tongue carrying plate.

2. A collapsible electric stove comprising a top plate having a flange defined opening therein and flanges at the edges thereof, a heating unit in said opening, and side walls having flanges at opposite ends thereof, the flanges at the upper ends of the side walls resting against the top plate in the space between the opening flange and edge flanges thereof when the stove is set up.

3. A collapsible electric stove comprising a top plate having a flange defined opening therein and flanges at the edges thereof, a heating unit in said opening, and side walls having flanges at opposite ends thereof, the flanges at the upper ends of the side walls resting against the top plate in the space between the opening flange and edge flanges thereof when the stove is set up, and

4. A collapsible electric stove comprising a top plate having a flange defined opening therein and flanges at the edges thereof, a heating unit in said opening, and side walls having flanges at opposite ends thereof, the flanges at the upper ends of the side walls resting against the top plate in the space between the opening flange and edge flanges thereof when the stove is set up, and tongues projecting from the edge flanges of the top plate which enter slots. in the side walls for securing the sidewalls to the top plate in the set up condition.

5. A collapsible electric stove comprising a top plate having an opening therein and flanges at the edges thereof, a heating unit in said opening,

side walls and a bottom plate having flanges at opposite ends thereof, said side walls having slots therein, and the flanges of the top plate having tongues projecting therefrom, which tongues, when the stove is set up, engage the slots in the side walls to secure the walls to the top plate, and, when the stove is collapsed, engage the flanges of the bottom plate to secure that plate to the top plate.
