Patent ID: 6848901

Claim:
An apparatus for controlling the height of a flame comprising: a reservoir for containing a flame-fueling liquid; a wick having a first end disposed within the reservoir and a second, flame-bearing end substantially located above the first end, whereby, when the flame-fueling liquid is supplied to the reservoir, the flame-fueling liquid is communicated up the wick to fuel a flame emanating from the flame-bearing end of the wick; a collar surrounding the wick, the collar having a top portion, a bottom portion and a central portion, the central portion having one or more perforations, the collar slidable along a vertical axis between a first position and a second position, wherein in the first position a top portion of the collar is located above the flame-bearing end of the wick, wherein in the second position the top portion of the collar is located below the flame-bearing end of the wick, so that in the first position the collar substantially blocks the flow of atmospheric air from reaching the flame-bearing end of the wick while allowing atmospheric air to reach the flame-bearing end of the wick through the perforations, and in the second position the collar does not substantially block the flow of atmospheric air from reaching the wick.
