Abstract
Abstract A candle structure for burning a fuel which is liquid at room temperature includes a hollow enclosure which alternatively may contain the fuel being consumed or may float upon the fuel, and rigid wick means, preferably in the form of one or more charcoal rods, supported with the upper end above the enclosure. The wick means extends into the enclosure, with its lower end either inside the enclosure, when the latter contains the flammable liquid, or extending through a lower wall of the enclosure when floating upon the liquid. Additional features include construction of the enclosure and/or the container in various decorative forms, and cooperative structure on a floating enclosure and on the fuel container for rotating the enclosure as it moves downwardly as the fuel is consumed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
209 words
A candle construction for use with fuel which is in liquid form at room temperature, wherein the fuel is either internal or external with respect to the candle construction, comprising: (a) a hollow enclosure having spaced upper and lower walls adapted alternatively to contain a liquid fuel within at least a lower portion thereof, and to float upon a liquid fuel within a container larger than said enclosure; (b) wick means which said liquid fuel will enter and travel upwardly by capillary action for combustion in an upper area of said wick means; (c) support means for engaging said wick means and supporting the latter with said upper area thereof above said enclosure and a portion thereof within said enclosure; and (d) said lower wall of said enclosure including an opening through which said wick means may selectively be passed, whereby substantially all the lower end of said wick means may be positioned within said enclosure when said liquid fuel is contained therein, or outside and below said enclosure when the latter is floating upon said liquid fuel, and further including a resilient member having an internal cross section corresponding to the external cross section of said wick means, whereby the latter substantially seals said opening when extending therethrough.

A candle construction for use with fuel which is in liquid form at room temperature, wherein the fuel is either internal or external with respect to the candle construction, comprising: (a) a hollow enclosure having spaced upper and lower walls adapted alternatively to contain a liquid fuel within at least a lower portion thereof, and to float upon a liquid fuel within a container larger than said enclosure; (b) wick means which said liquid fuel will enter and travel upwardly by capillary action for combustion in an upper area of said wick means; (c) support means for engaging said wick means and supporting the latter with said upper area thereof above said enclosure and a portion thereof within said enclosure; and (d) said lower wall of said enclosure including an opening through which said wick means may selectively be passed, whereby substantially all the lower end of said wick means may be positioned within said enclosure when said liquid fuel is contained therein, or outside and below said enclosure when the latter is floating upon said liquid fuel, and further including a resilient member having an internal cross section corresponding to the external cross section of said wick means, whereby the latter substantially seals said opening when extending therethrough.
Claim 3
Dependent Claim
20 words
The invention according to claim 1 wherein said lower wall means forms at least a portion of said support means.
Claim 4
Dependent Claim
38 words
The invention according to claim 1 and further including a container larger than said enclosure at least partially filled with a liquid fuel, said wick means extending through said opening into said fuel with said enclosure floating thereon.
Claim 5
Dependent Claim
52 words
The invention according to claim 3 and further including internal, first guide means on said container, and external, second guide means on said enclosure in mating engagement with said first guide means, whereby said enclosure descends as liquid fuel within said container is consumed in a path established by said guide means.
Claim 6
Dependent Claim
26 words
The invention according to claim 4 wherein said path is spiral, whereby said enclosure is rotated by said guide means as it descends within said container.
