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.

First claim

What is claimed is:

1. A device comprising:
an outer shell forming a outer shroud on an upper end thereof;
an inner shroud affixed to a flame bowl at a seam between the inner shroud and flame bowl;
a support having a first, predetermined height and engaging the outer shell at a second, predetermined height inside the outer shell, and engaging the inner shroud and the flame bowl at the seam to support the inner shroud and flame bowl at a height that is elevated within the outer shell relative to second, predetermined height inside the outer shell;
wherein the flame bowl is supported at a height that is at least partially below an upper rim of the outer shroud and the inner shroud is supported at a height that is at least partially above and upper rim of the outer shroud; and
wherein the flame bowl defines a wick holder; and
wherein the support defines a plurality of perforations providing fluid communication of air therethrough to below the flame bowl.

2. The device of claim 1 , wherein the flame bowl is supported at a height that is partially above the upper rim of the outer shroud.

3. The device of claim 1 , wherein the flame bowl is affixed to a liquid fuel reservoir and supports the reservoir at a predetermined height within the outer shell.

4. A device comprising:
a flame bowl defining a wick holder and surrounded by a first, inner shroud;
a shell having a second, outer shroud on an upper portion thereof, the second, outer shroud circumscribing at least a portion of the first, inner shroud; and
a support having a predetermined height and engaging the shell to support the flame bowl and the first, inner shroud in a fixed relationship with respect to the second, outer shroud such that the flame bowl and first, inner shroud are elevated within the shell relative to a height at which the support engages the shell;
wherein the supports joins the flame bowl and shroud proximate a seam between the flame bowl and first, inner shroud and defines a plurality of perforations that allow for fluid communication of air below the flame bowl.

5. The device of claim 4 , wherein the support is perforated.

6. The device of claim 4 , wherein the flame bowl further comprises a textured surface surrounding the wick holder.

7. The device of claim 4 , 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.

8. The device of claim 4 , further comprising a snuffer cap sized to substantially cover the first shroud.

9. The device of claim 8 , further comprising a retainer hook affixed to the shell for retaining the snuffer cap when not in use.

10. The device of claim 4 , wherein the predetermined height of the support is at least 1.25 inches.

11. The device of claim 4 , wherein the flame bowl is supported at a level at least partially below an adjacent upper rim of the outer shroud.

12. A device comprising:
a flame bowl defining a wick holder 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 heat dissipating support; and
a second shroud at least partially surrounding the first shroud and supported by the torch body;
wherein the heart dissipating support has a predetermined height and elevates the flame bowl from a height within the torch body at which the support engages the torch body; and
wherein the heat dissipating supports proceeds laterally away from the flame bowl and defines a plurality of perforations that allow for fluid communication of air through the heat dissipating support below the flame bowl.

13. The device of claim 12 , 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.

14. The device of claim 13 , 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.

15. The device of claim 12 , further comprising a fuel canister containing the fuel supply and attached to the flame bowl suspended at least partially within the torch body.

16. The device of claim 15 , wherein the fuel canister is connected to the flame bowl by a threaded fitting.

17. The device of claim 12 , wherein the support comprises a heated dissipating perforated metal support.

18. The device of claim 12 , wherein the support comprises a heat isolating bridge.

19. The device of claim 12 , wherein the flame bowl is supported entirely below any portion of the second shroud on the torch body.

20. The device of claim 12 , wherein the flame bowl is supported at least partially above the second shroud on the torch body.
