G.I. pocket stove

During World War II, the U.S. government tasked Coleman to develop a compact stove for military use.

The stove had to be lightweight, be no larger than a quart-sized thermos bottle, burn any kind of fuel, and operate in weather from −60 to +125 °F (−51 to 52 °C).

An integrated hand-operated cleaning needle is used to remove soot or other impurities that can clog the burner tip.

Once the flame burns steadily for 2 to 3 minutes and the burner head is sufficiently heated up, the control valve is opened as far as possible.

[citation needed] The heat of the burner head is then sufficient to vaporize the pure fuel prior to combustion.

Mountain Gas Stove[citation needed] M-1942 (later, M-1942-MOD PW-1-45) was made by Coleman, Prentiss Wabers (a.k.a Preway) and Aladdin.

[citation needed] The inventor of the stove was Bestor Robinson, Vice President of the San Francisco Bay Chapter of the Sierra Club, a rock climber and skier.
