  "claims": [
    "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.",
    "5. The device of claim 1, further comprising a snuffer cap sized to substantially cover the first shroud.",
    "6. The device of claim 5, further comprising a retainer hook affixed to the shell for retaining the snuffer cap when not in use.",
    "7. A device comprising: 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."

  "description_excerpt": "This disclosure relates to liquid fueled torches in general and, more particularly, to a liquid fueled torch that isolates heated components from a user.\n\nLiquid fueled torches are utilized for a number of purposes such as lighting, decoration, and pest repellence. Some fuel and torch combinations operate at extremely high temperatures. This is particularly so where a large flame presence is desired, or where high temperatures are utilized to disperse repellants or other useful substances. For safety reasons, torches are rarely left unattended; and some users will want to place torches into storage as soon as possible after use. Sometimes it may also be desirable to relocate a torch that is operating, or has recently been operating.\n\nWhat is needed is a system and method for addressing the above, and related, issues.\n\nThe invention of the present disclosure, in one aspect thereof, comprises 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.\n\nIn some embodiments, the support is perforated. An interior of the shell may have a lip providing a resting place for the support. In some embodiments the device has a slot defined in the lip, and 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.",
