Torch and torch attachment

摘要

An attachment for a torch includes a combustion cone mounted on a fuel delivery tube. The combustion cone bounds a combustion chamber and has an inlet through which fuel from the tube enters the chamber to create a flame when the torch ignites the fuel. The cone diverges away from the inlet and to an outlet to enable the flame to diverge and spread within the chamber. The chamber substantially contains the flame therein. At least one apertured radiator, and preferably, a pair of apertured radiators, is mounted in the chamber in direct contact with the flame, and heated by the flame to a temperature sufficient to cause each radiator to radiate infrared radiation through and past the outlet. A tipping-resistant holder holds a fuel canister of the torch upright when placed on a support surface.

主权项

1. An attachment for a torch for igniting fuel and air to produce a flame in a burn tube, the attachment comprising:
a combustion cone mounted on the burn tube and bounding an internal chamber, the combustion cone having an inlet through which the flame enters the chamber, and an outlet spaced away from the inlet along a longitudinal direction, the outlet being larger in opening size than the inlet, the combustion cone diverging along the longitudinal direction away from the inlet and to the larger outlet to enable the flame entering the chamber to diverge and spread within the chamber along the longitudinal direction; and at least one apertured radiator mounted in the chamber and extending transversely of the longitudinal direction across the outlet, the radiator being positioned in direct contact with, and heated by, the spread flame to a temperature sufficient to cause the radiator to radiate thermal radiation through and past the outlet.
