ABSTRACT:
A portable, flambeau torch utilizing liquid propane gas, butane, or the like fuel in contrast to the fluid kerosene or "white gas" of traditional flambeau devices. A backpack support (1) for the user or operator holds the gas containment tank (6) and first regulator stage (10). A torch frame (18-19/20-22) carrying a multiple number of burners (23a-d) is connected to the tank by means of a quick disconnect (12) hose (11) and an internal passageway formed by the hollow, closed ended, tubular members making up the torch frame. A hand manipulated, quick release, kill switch (14) is held down by the operator to allow the gas to continuously flow to the burners during use (see FIG. 3). Concentric cylindrical members (23 and 25 ) form combustion chambers (32) for the burners.
