Abstract
The apparatus described and illustrated is a camping furnace used for cooking or warming food outdoors. The apparatus surrounds the burning fuel and directs smoke upward. Fuel and heat are used efficiently and the danger of the spread of fire is minimized. When it is safe to do so, the apparatus may be easily moved, leaving ash and spent fuel behind. Preferably, the enclosure wall of the furnace is made of separable and/or hinged sections, for adapting the furnace to a flatter, more compact shape for storage and transport.

A camping furnace for use with a camp fire or ashes on the ground, the furnace consisting of:
- (a) an enclosure having a generally vertical, generally cylindrical enclosure wall, the enclosure having a diameter, an open top, and an open bottom for placement on the ground, wherein the length of the cylindrical enclosure wall from the open top to the open bottom equals or exceeds the diameter of the enclosure;
- (b) said cylindrical enclosure wall defining an interior space for receiving the camp fire or ashes and having a bottom edge nears the open bottom and vertical louvre openings near the bottom edge for permitting air flow tangentially into interior space to swirl in the same direction and having a top edge near the open top, there being no openings near the top edge and no openings at or above the midway point of the enclosure wall;
- and
- (c) wherein, when the enclosure wall is lifted off the ground, the camp fire or ashes fall out of the furnace through the open bottom.
A camping furnace for use with a camp fire, the furnace consisting of:
- (a) an enclosure having a generally vertical, generally cylindrical enclosure wall with the enclosure having a diameter, an open top, and an open bottom, said cylindrical enclosure wall defining an interior space for receiving the camp fire and said wall having a plurality of separable semi-cylindrical sections, wherein the length of the cylindrical enclosure wall from the open top to the open bottom equals or exceeds the diameter of the enclosure;
- (b) connection means for connecting the plurality of sections together during use;
- (c) disconnection means for separating at least two of the sections from each other;
- and
- (d) the sections having a bottom edge near the open bottom and vertical louvre openings near the bottom edge for permitting air flow tangentially into said interior space to swirl in the same direction and having a top edge near the open top, there being no openings near the top edge and no openings at or above the midway point of the enclosure wall.
