Abstract
A generally cylindrical casing is hollow, and is supported by a base so that the axis of the casing axis is horizontal. A vertical partition divides the casing into a fire chamber and a smaller exhaust chamber. The smaller chamber is vented to the outside atmosphere by a chimney. The partition does not completely isolate the chambers, but enables them to be interconnected through a small gap at its bottom. Extending rearwardly along the curved portion of the casing are two oppositely disposed parallel elongated air intake slits at the level of the bottom of the partition. One of these slits is defined by the gap between a hinged lid allowing access to the fire chamber and the casing. The major portion of the section of the casing that surround the fire chamber is of glass, and the bottom of the fire chamber is lined with fire clay.
