ABSTRACT:
This is a catalytic warmer or heater which may be made in different sizes and shapes. A chimney section top has an opening through which a heatable material container is insertable, and which rests on an X-frame supported on punched-in tongues providing draft apertures for the chimney, while a lower spaced series of punched-in tongues rest on a catalyst containing cage which, in turn, rests on a flange of fuel cartridge section below having a wick extending up from the cartridge to be lighted temporarily to initiate the catalytic combustion process. The supporting X-frame has a depending cylinder providing a snuffer to snuff out the wick and permit the catalytic combustion to continue. The catalytic combustion is stopped when desired by merely turning the entire heater or warmer upside down and then removing the fuel cartridge containing section, now on top, from the chimney section, now on bottom, the catalyst cage remaining with the chimney section and thus separated from the cartridge fuel section.
