Abstract
Abstract A candle includes a candle body formed of a quantity of candle wax. In one embodiment, a stationary wick is embedded within the candle body and a movable wick is supported within the candle body by a bimetallic coil spring. The heat produced by the burning of the movable and stationary wicks causes a relative motion between the movable wick and the stationary wick. In an alternate embodiment a pair of movable wicks are supported by a pair of bimetallic coil springs such that the heat produced by the burning wicks causes the coil springs to join the movable wicks to produce a combined flame. In a still further alternate embodiment, a pair of bimetallic coil springs and a central wick are supported within a candle body. A pair of upwardly extending arms are coupled to the bimetallic coil springs and support a corresponding pair of heart-shaped members. The heat produced by the central candle wick is operative upon the bimetallic coil springs to cause the heart-shaped members to be joined as the candle burns.
