Abstract

A new type of portable, collapsible wood burning stove that can be easily disassembled and assembled for use with very small pieces of wood or coal and when so used is environmently efficient comprising relatively small front and back metal plates having along both sides a cut out slot extending from the bottom edge, two other plates having along both sides a cut out slot extending from the top edge, the front and back plates being removably joined to the side plates to form a box structure by having the cut out slots of the front and back plates inserted down into the slots of the other plates, the height of the front and back plates being adjust so that their top edges are above the edges of the other plates and air space remains below the bottom edge of the of such plates, a metal grate and ash pan being inserted inside the box structure and held in place by protruding elements from the side plates, and method for using the same.

Claims

1. A portable, collapsible wood burning stove comprising in the assembled condition:

a. a front and back metal plate both having a top and bottom edge and two side edges and having an elongated cut out slot extending from the bottom edge part way up the plate paralleling the side edges,

b. two side metal plates both having a top and bottom edge and two side edges and having an elongated cut out slot extending from the top edge part way down the plate paralleling the side edges,

c. the front and back metal plates being removably joined to the side plates to form a box type structure by having the elongated cut out slots of said front and back plates inserted into the cut out slots of the side plates,

d. the height of the front and back plates being adjusted so that the top edge of the said front and back plates are above the top edge of the side plates and air space is provided below the bottom edge of the front and back plates,

e. a metal grate fitting between the two side plates,

f. a solid metal ash pan fitting between the two side plates and below the said grate but above the bottom edge of the side plates,

g. and means protruding through the side plates to provide support for the above noted grate and ash pan.

2. A stove as in claim 1 wherein the four plates have a size varying from 3 to 10 inches and each side has a plurality of vent holes in the middle section thereof.

3. A stove as in claim 1 wherein the four plates have a size varying from about 10.1 to 15 inches and there are a plurality of vent holes in at least the two side plates.

4. A wood burning stove as in claim 1 wherein the metal plates are prepared from aluminum sheeting.

5. A wood burning stove as in claim 1 wherein vent holes are contained in at least one of the four metal plates.

6. A wood burning stove as in claim 1 wherein the protruding means to support the grate and ash pan comprise screw means introduced through the outside of the two side plates.

7. A wood burning stove as in claim 1 wherein a grill plate is placed on top of the top edges of the front and back plates.

8. A modified wood burning stove as in claim 1 wherein the front metal plate is removed and attached by means of the cut out grooves to the top of the side plates in front of the top edges of the back plate, and a metal bar is placed in the grooves of the side plates in place of the front metal plate.

9. A process for using the stove as defined in claim 1 which comprises placing a fuel source on the grate, igniting the fuel source and then placing the cooking utensil on the top edges of the plates and allowing the generated heat to effect the desired cooking.
