Abstract
A liquid hydrocarbon burner of the type having a vertically adjustable wick, comprises an inner ring on which the wick is mounted, an intermediate ring outside the inner ring and an outer ring outside the intermediate ring. The rings are relatively rotatably and relatively vertically movable; and guide pins disposed in slots in the rings ensure that when the outer ring is rotated, the inner ring will move vertically. Gas supply is provided, with an electrical circuit for igniting the gas which in turn ignites the wick. The gas supply and the ignition of the gas supply are controlled by rotation of the outer ring, in such a way that the gas is supplied and ignited once when the wick is raised, and again when the wick is lowered, this latter ignition serving to burn the fumes from the liquid hydrocarbon which would otherwise cause odors after the wick is extinguished.
