Abstract
A gas operated lantern includes a regulator having a simple mechanism allowing a user to start or stop the flow of gas through the regulator. The regulator preferably exhausts an air/gas mixture in the same direction as which gas enters the regulator. The regulator includes a diaphragm assembly which presses down on a valve assembly to open the valve assembly. A stem enters the regulator and is turnable by the user to raise the diaphragm assembly and thus cause the valve assembly to close. The lantern also includes an automatic choke. The choke is preferably a strip of metal located in the burner tube of the lantern which acts to close off a portion of the burner tube when the lantern is cold, causing the air/fuel mixture to become richer and thus easier to light. As the lantern heats up, the choke straightens to open the burner tube, allowing a greater flow of air through the lantern and causing the air/fuel mixture to become leaner and thus raising the efficiency of the lantern.
