Abstract
Abstract A wick-burning candle is provided which includes a body of conventional, moldable, combustible material and which is characterized by the fact that it further includes a multiplicity of light transmitting fibers whose introductory ends are directly exposed to the candle flame and whose light emitting ends are located at distributed points in the periphery of the candle, so that the lighting of the candle causes the points of light emission in the candle body to glow.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
A novel candle which includes, in combination, a body composed of moldable and combustible material, a wick which serves in the conventional way as a light producing source when ignited, and a multiplicity of optical fibers each having a generally vertically disposed light-receiving upper end which extends through the upper end of the candle body and a generally horizontally disposed light emitting lower end which extends through the lateral wall of the candle body, each optical fiber having the capability of picking up light from the burning wick at its upper end, transmitting it through the candle body and radiating it through its lower end, so that numerous spots of illumination originating at the flame appear in the lateral walls of the candle.
Claim 2
Dependent Claim
123 words
A novel candle which includes, in combination, a body composed of moldable and combustible material, a wick which serves in the conventional way as a light producing source when ignited, and a multiplicity of optical fibers each having a generally vertically disposed light-receiving upper end which extends through the upper end of the candle body and a generally horizontally disposed light emitting lower end which extends through the lateral wall of the candle body, each optical fiber having the capability of picking up light from the burning wick at its upper end, transmitting it through the candle body and radiating it through its lower end, so that numerous spots of illumination originating at the flame appear in the lateral walls of the candle.
Claim 3
Dependent Claim
24 words
A novel candle as set forth in claim 1 in which each optical fiber includes a light conducting core and a light reflecting clad.
Claim 4
Dependent Claim
35 words
A novel candle as set forth in claim 2 in which the core and clad of each optical fiber are both transparent and the core has a substantially higher index of refraction than the clad.
Claim 5
Dependent Claim
48 words
A novel candle as set forth in claim 1 in which each optical fiber is responsive to the heat of the candle flame, being caused thereby to recede as the candle is consumed, and to maintain at the upper end of each fiber a globular, light condensing formation.
Claim 6
Dependent Claim
30 words
A novel candle as set forth in claim 1 in which each optical fiber includes at its exposed lower end a globular structure through which the received light is radiated.
