ABSTRACT:
A positive oil candle wick advancing and retracting mechanism including a candle cap having formed therethrough an elongated bore for passage of the wick, at least three elongated tubular elements mounted in the cap immediately below the bore for rotational movement in close equiangular arrangement about a central axis passing upward through the bore, a series of spiral threads formed along the greater length of the outside surface of the elements to engage the wick uniformly thereabout, a series of outwardly facing gear teeth formed circumferentially about a shorter length of the outside surface of the elements spaced apart from the spiral threads, and a candle cap support base including a first mechanism for retaining the candle cap in aligned rotational position thereon, a second mechanism for attaching the base to a candle oil receptacle, and a series of inwardly facing gear teeth formed in a circumferential ring about the interior of the base and arranged for engagement with the outwardly facing gear teeth of the tubular elements so that rotational movement of the candle cap with respect to the base causes the tubular elements to rotate in unison against the wick causing the spiral threads to advance the wick upward and retract it downward through the bore.
