Outdoor lamp with adjustable wick

Abstract

The invention pertains to an outdoor lamp with an adjustable wick. The fluid fuel is contained within a canister that is positioned within a conventional lamp holder. Within the cover of the lamp holder is a grooved rotating wheel that is in contact with the wick. A support shaft is connected to the rotating wheel and extends outside of the cover. Rotation of the shaft causes rotation of the wheel, whereby the wick is moved up and down to change the amount of the wick that is within the reservoir of the fluid fuel.

I claim:  
     
         1 . An outdoor lamp containing a removable and replaceable canister of fluid fuel, a lamp holder in which said canister is removably contained, a cover for said lamp holder and a wick that extends through said cover and into said fluid fuel within said canister, wherein the improvement comprises said lamp cover including a stem extending downward from the top of said cover towards the interior of said cover and an elongate slot being defined along a longitudinal surface of said stem, support plates secured to said stem and extending in a direction that is perpendicular to the longitudinal axis of said stem and each supporting plate including a locating hole which are in alignment, a support shaft positioned within said locating holes of said supporting plates and having a first end extending out of said cover and including a gripping surface, and a grooved rotating wheel supported by said support shaft, wherein said grooved wheel rotates partially within said elongate slot and portions of said grooved wheel contact said wick, whereby rotation of said shaft causes rotation of said grooved wheel and up and downward movement of said wick.  
     
     
         2 . An outdoor lamp comprising a removable and replaceable canister of fluid fuel and a lamp cover that is removably affixed to said canister of fluid fuel, wherein the improvement comprises said lamp cover including a central stem extending internally along the length of said lamp cover and said stem having a central passageway in alignment with an opening in said canister; a wick orientated and positioned within said central stem with one end of said wick being suspended within an interior of said canister and a second end of said wick extending upward through said stem and out from the top of said lamp cover; a grooved, rotating wheel secured within said lamp cover and teeth of said rotating wheel extending into said stem and contacting said wick; and, a shaft secured to said rotating wheel and extending out from said lamp cover, whereby rotation of said shaft causes rotation of said rotating wheel and thereby causes vertical movement up and down of said wick.  
     
     
         3 . An outdoor lamp according to  claim 2 , further comprising a globe fitted over said lamp cover.
