ABSTRACT:
In a liquid fuel combustion apparatus, the upper end of a wick is ready to be ignited when it projects upward from a pan portion, and is extinguished when it is withdrawn downward from the pan portion. The wick moves up and down as a first operating lever swings around an operating shaft. If the first operating lever is lowered, a retaining lever is raised by a bent strip. When the wick is in a position for high-temperature combustion, a retaining portion of the retaining lever engages a receiving portion of an interlocking plate. When the first operating lever is lowered, its engaging pin engages an engaging slit of an adjusting lever. If a knob of a thermal power control plate is moved up and down along a slot, the adjusting lever swings around a support pin, and the first operating lever swings slightly through the engaging pin and the engaging slit. Thus, the wick is moved up and down in a combustion region for adjustment of thermal power. If an extinction lever is operated or if a movement-sensitive pendulum is activated, the retaining portion is disengaged from the receiving portion to cause the operating shaft to rock at a stroke in an extinction direction. Thus, the wick is extinguished in an instant.
