Abstract
Abstract A burner is formed from a metal can having a removable cover with at least three wires joined together at the center of the can near the top and extending outwardly therefrom in substantially uniformly spaced relationship to the side wall of the can where they are integrally connected to the upper ends of vertical portions extending downwardly to the bottom of the can. A metal plate resting on the wires is provided with a central opening, and a metal heat conductor is mounted on the wires at their junction and extends up through the plate opening. Wicks means extend from the bottom of the can up through the plate opening beside the heat conductor, and a body of wax beneath the said plate fills the can around the wick means, whereby when the burner is burning, the wires will conduct heat from the central heat conductor.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
A burner comprising a metal can having a removable cover, at least three wires joined together at the center of the can near the top and extending outwardly therefrom in substantially uniformly spaced relation to the side wall of the can where they are integrally connected to the upper ends of vertical portions extending downwardly to the bottom of the can, a metal plate resting on said wires and provided with a central opening, a metal heat conductor mounted on the wires at the junction thereof and extending up through said plate opening, wick means extending from the bottom of the can up through said plate opening beside said heat conductor, and a body of wax beneath said plate and filling the can around said wick means, whereby when the burner is burning, said wires will conduct heat from said heat conductor down into the wax to help melt it.
Claim 2
Dependent Claim
150 words
A burner comprising a metal can having a removable cover, at least three wires joined together at the center of the can near the top and extending outwardly therefrom in substantially uniformly spaced relation to the side wall of the can where they are integrally connected to the upper ends of vertical portions extending downwardly to the bottom of the can, a metal plate resting on said wires and provided with a central opening, a metal heat conductor mounted on the wires at the junction thereof and extending up through said plate opening, wick means extending from the bottom of the can up through said plate opening beside said heat conductor, and a body of wax beneath said plate and filling the can around said wick means, whereby when the burner is burning, said wires will conduct heat from said heat conductor down into the wax to help melt it.
Claim 3
Dependent Claim
21 words
A burner according to claim 1, in which said wick means include a tubular with a wire extending lengthwise through it.
Claim 4
Dependent Claim
35 words
A burner according to claim 1, in which said wick means include a fiber glass core, wicks against the side of the core, and a binder surrounding the core and pressing the wicks against it.
Claim 5
Dependent Claim
40 words
A burner according to claim 3, in which said wicks are lengths of a single tubular member with a wire extending lengthwise through it, said member being provided with vertical loops extending up through said plate opening between said wires.
Claim 6
Dependent Claim
22 words
A burner according to claim 4, in which there are only three of said first mentioned wires and three of said loops.
Claim 7
Dependent Claim
31 words
A burner according to claim 1, in which said heat conductor has a hollow stem receiving the upper ends of said wires, and a flange surrounds the top of the stem.
Claim 8
Dependent Claim
49 words
A burner according to claim 1, in which said plate is spaced downwardly from the top of the can to provide a receptacle above the plate for cakes of wax to melt and run down beneath the plate, whereby the supply of wax in the burner can be replenished.
Claim 9
Dependent Claim
57 words
A burner according to claim 1, in which the bottom of the can is provided with a central hole, and a screw plug normally extends up through said hole to seal it, the screw plug being removable to permit the upper end of a vertical handle to be screwed up into said hole to support the can.
