Abstract
An improved camp lantern comprising a spool fuel/air valve with OFF, START and RUN modes of operation is described. The spool valve is contained within a cylindrical valve chamber having fuel and air inlets and an outlet port leading to the lantern generator. The spool valve shaft also comprises a ramp contacting a cam follower for driving a rod and orifice cleaning needle. The needle enters and clears the generator orifice when the valve is in the OFF position. Thus, operating the valve in normal use also automatically clears the generator orifice. In addition to the operating convenience of this valve assembly, the parts count is low and the parts are easily machinable, making this lantern valve assembly reliable and economically producable in commercial quantities.
