Abstract
Abstract A device capable of burning household vegetable oil and producing a candle-like flame is disclosed. It includes a heat-resistant upright glass tube within which a fibrous wick is positioned, extending a short distance out the top. For supporting the tube and wick in a generally flat-bottomed container, such as a small drinking glass, a foot or stand having horizontally-extending projections and an upright sleeve may be connected to the bottom of the tube by insertion of the tube end in the sleeve. When the assembled tube, wick and foot are placed in a container and vegetable oil is added, at least to the level of the bottom of the wick, the extending portion of the wick may be ignited to produce a candle-like flame. The container is preferably transparent so that light is radiated in all directions, and a special container may be provided for seating atop a light-transmitting rod, so that light from the flame illuminates the rod.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
179 words
An oil-burning illuminating device for producing a candle-like flame, comprising: a container having a closed bottom and an open top; a tubular, heat-resistant wick holder, open at both ends; a fibrous wick retained in the wick holder, extending outwardly from one end; and means associated with the other end of the wick holder and with the container bottom for retaining the wick holder upright in the container with said one end upward, said means comprising a flat portion of the container bottom and a foot connected to said other end of the wick holder, having horizontally-extending projections for seating flatly on said flat portion, said foot including an upwardly-extending sleeve sized to fit tightly over said other end of the wick holder for connecting the foot to the wick holder, said sleeve being open at its bottom to admit oil to the wick holder and the wick, whereby combustible oil may be placed in the container to a level at least above said other end of the wick holder and burned at the outwardly extending portion of the wick.
Claim 2
Dependent Claim
179 words
An oil-burning illuminating device for producing a candle-like flame, comprising: a container having a closed bottom and an open top; a tubular, heat-resistant wick holder, open at both ends; a fibrous wick retained in the wick holder, extending outwardly from one end; and means associated with the other end of the wick holder and with the container bottom for retaining the wick holder upright in the container with said one end upward, said means comprising a flat portion of the container bottom and a foot connected to said other end of the wick holder, having horizontally-extending projections for seating flatly on said flat portion, said foot including an upwardly-extending sleeve sized to fit tightly over said other end of the wick holder for connecting the foot to the wick holder, said sleeve being open at its bottom to admit oil to the wick holder and the wick, whereby combustible oil may be placed in the container to a level at least above said other end of the wick holder and burned at the outwardly extending portion of the wick.
Claim 3
Dependent Claim
165 words
An oil-burning illuminating device for producing a candle-like flame, comprising: a container having a closed bottom and an open top; a tubular, heat-resistant wick holder, open at both ends; a fibrous wick retained in the wick holder, extending outwardly from one end; means associated with the other end of the wick holder and with the container bottom for retaining the wick holder upright in the container with said one end upward; and a stand of clear, light-conducting material; the container being of transparent material and having an upwardly-extending recess in its bottom, shaped to receive the top of the stand, whereby combustible oil may be placed in the container to a level at least above said other end of the wick holder and burned at the outwardly extending portion of the wick and whereby light from the oil flame at the top of the wick passes through the container bottom and into the stand, and light from the flame is emitted in nearly all directions.
Claim 4
Dependent Claim
165 words
An oil-burning illuminating device for producing a candle-like flame, comprising: a container having a closed bottom and an open top; a tubular, heat-resistant wick holder, open at both ends; a fibrous wick retained in the wick holder, extending outwardly from one end; means associated with the other end of the wick holder and with the container bottom for retaining the wick holder upright in the container with said one end upward; and a stand of clear, light-conducting material; the container being of transparent material and having an upwardly-extending recess in its bottom, shaped to receive the top of the stand, whereby combustible oil may be placed in the container to a level at least above said other end of the wick holder and burned at the outwardly extending portion of the wick and whereby light from the oil flame at the top of the wick passes through the container bottom and into the stand, and light from the flame is emitted in nearly all directions.
Claim 5
Dependent Claim
140 words
An oil-burning illuminating device for producing a candle-like flame, comprising: a tubular, heat-resistant wick holder, open at both ends; fibrous wick retained in the wick holder, extending outwardly from one end; a foot removably retained to the other end of the wick holder, including a sleeve sized to fit tightly over said other end, said sleeve being open at its bottom to admit oil to the wick holder and the wick, and means connected to the sleeve for retaining the wick holder vertically on a flat surface with said one end upward; whereby the wick holder and attached foot may be positioned on the flat bottom of a container and combustible oil may be placed in the container to a level at least above said other end of the wick holder and burned at the outwardly-extending portion of the wick.
