Abstract

A device having a flame bowl surrounded by a first, inner shroud. The device includes a shell having a second, outer shroud on an upper portion thereof, the outer shroud circumscribing at least a portion of the first shroud, and a support supporting the flame bowl and the first shroud in a fixed relationship with respect to the outer shroud.

Claims (27)

1. A device comprising:

a flame bowl surrounded by a first. inner shroud:

a shell having a second, outer shroud on an upper portion thereof, the outer shroud circumscribing at least a portion of the first shroud;

a support supporting the flame bowl and the first shroud in a fixed relationship with respect to the outer shroud;

a lip on an interior of the shell. the lip providing a resting place for the support;

a slot defined in the lip;

a tab protruding from the support that interfits with the lip to retain the inner shroud in a fixed rotational relationship with respect to the outer shroud; and

wherein the first and second shrouds are each cut at an angle relative to the flame bowl such that each shroud has a high side and a low side, the high sides and the low sides being in substantially the same radial location with respect to the flame bowl.

2. The device of claim 1 , wherein the support is perforated.

3. The device of claim 1 , wherein the flame bowl further comprises a wick holder surrounded by a textured surface.

4. The device of claim 1 , wherein the flame bowl further comprises a threaded connection that interfits with a threaded neck of a fuel canister that is suspended from the flame bowl at least partially within the shell.

a flame bowl containing a wick in fluid communication with a fuel supply;

a support attached to the flame bowl;

a torch body at least partially surrounding a heat dissipating support;

a first shroud in relative close proximity to the flame bowl and supported relative to the torch body by the support; and

a second shroud at least partially surrounding the first shroud and supported by the torch body;

wherein each of the shrouds provides a relative high side and a relative low side and the high sides and low sides are fixed in the same rotational position relative to the flame bowl; and

wherein the torch body provides a slotted lip on an interior thereof, the slotted lip fitting with a tab on the support for maintaining the rotational positions of the shrouds.

8. The device of claim 7 , further comprising a fuel canister containing the fuel supply and attached to the flame bowl suspended at least partially within the torch body.

9. The device of claim 8 , wherein the fuel canister is connected to the flame bowl by a threaded fitting.

10. The device of claim 7 , wherein the support comprises a heated dissipating perforated metal support.

11. The device of claim 7 , wherein the support comprises a heat isolating bridge.

12. The device of claim 7 , wherein the flame bowl is supported entirely below a level of the second shroud on the torch body.

13. The device of claim 7 , wherein the flame bowl is supported at least partially above a level of the second shroud on the torch body.
