ABSTRACT:
A fuel control system for burners such as gasoline lanterns provides automatic tip cleaning and adjustable light output. The fuel system includes a burner, a fuel tank, and a fuel conduit for supplying fuel to the burner. A valve is interposed in the fuel conduit for opening and closing fuel flow. The conduit has a fuel outlet orifice, and a tip cleaning needle is reciprocable within the conduit for cleaning the orifice. The valve and the tip cleaning needle are controlled by a rotatable control shaft which extends perpendicularly to the conduit and which includes an eccentric pin. The eccentric pin extends above a valve block into a slot in an eccentric follower. The control shaft is rotatable between an off position in which the valve is closed and the end of the tip cleaning needle is positioned in the orifice, a dim position in which the valve is on and the tip cleaning needle is positioned in the orifice, and a full on position in which the valve is open and the tip cleaning needle is withdrawn from the orifice.
