Abstract

A system includes a torch top having a wick holder extending along a portion of a wick in contact therewith for retaining the wick to extend from a lower side of the torch top to a level above an upper side the torch top. The system includes an adjustment sleeve exterior and concentric to the wick holder and moveable to extend upwardly to such an elevation as to be at least partially above an uppermost portion of the wick holder.

First claim

What is claimed is:

1. A system comprising:
a torch top having a wick holder extending along a portion of a wick in contact therewith for retaining the wick to extend from a lower side of the torch top to a level above an upper side of the torch top;
an adjustment sleeve exterior and concentric to the wick holder and moveable to extend upwardly to such an elevation as to be at least partially above an uppermost portion of the wick holder; and
an enclosure that houses at least a portion of the adjustment sleeve when the sleeve is in a retracted position;
a fitting for a fuel reservoir in a fixed relationship with respect to the enclosure
wherein the enclosure encompasses at least a portion of the wick holder;
wherein the enclosure is partially above, and partially below, the fitting.

2. The system of claim 1 , further comprising an adjustment knob effective to raise and lower the adjustment sleeve.

3. The system of claim 2 , further comprising a pinion in a rigidly fixed relationship with the adjustment knob and a rack affixed to the adjustment sleeve, the rack and pinion operating in response to rotation of the adjustment knob to raise and lower the adjustment sleeve.

4. The system of claim 3 , further comprising a shaft interposing the adjustment knob and the pinion such that the adjustment knob is spaced apart from the adjustment sleeve.

5. The system of claim 1 , wherein the wick holder, the adjustment sleeve, and the fitting are all concentric with respect to one another.

6. The system of claim 1 , further comprising a bracket on the enclosure affixing a shaft having a pinion affixed thereto to the enclosure, the pinion engaging with the adjustment sleeve to raise and lower the adjustment sleeve by rotation of the shaft.

7. The system of claim 6 , further comprising a spring interposing the bracket and a fastener affixed to the shaft so as to impart friction when the shaft is rotated.

8. A system comprising:
a torch lid having a wick holder that grips a wick by contact forces along a length of the wick;
a flame adjustment sleeve concentric to the wick holder and extendible from a lowered position where at least a portion of the wick is exposed above the wick holder and a raised position wherein the wick is covered by the flame adjustment sleeve above the wick holder;
a pinion in contact with the flame adjustment sleeve that elevates and lowers the flame adjustment sleeve between the lowered and raised positions when rotated;
a knob for rotating and counter rotating the pinion to raise and lower the flame adjustment sleeve; and
an enclosure encompassing at least a portion of the wick holder and the flame adjustment sleeve;
wherein the enclosure further comprises an upright wall bounded at a top thereof by an enclosure top and on a bottom thereof by an enclosure base.

9. The system of claim 8 , further comprising a rack rigidly affixed to the flame adjustment sleeve in a vertical orientation to mesh with the pinion to drive the flame adjustment sleeve in response to rotation and counter rotation of the knob.

10. The system of claim 8 , wherein the enclosure top defines an opening sized to permit passage of the wick and elevation and lowering of the flame adjustment sleeve above the enclosure top.

11. The system of claim 10 , wherein the enclosure has a bracket affixed thereto that retains a shaft affixed to the pinion such that the pinion remains in contact with the rack.

12. The system of claim 11 , further comprising a cutout defined in the enclosure top and a portion of the upright wall that allows the pinion to remain in contact with the rack inside the enclosure, and allows the rack to extend beyond the enclosure top.

13. The system of claim 12 , further comprising a fuel reservoir fitting in a fixed relationship with respect to the enclosure.

14. The system of claim 13 , wherein the wick holder, the flame adjustment sleeve, and the fuel reservoir fitting are concentric with respect to one another.

15. The system of claim 14 , further comprising an upper platform interposing the fuel reservoir fitting and the enclosure, the upper platform bifurcating the enclosure such that the bracket is above the upper platform and a portion of the enclosure extends below the upper platform.
