Abstract
A lantern includes an elongated tubular mantle which is attached to a burner assembly by a spring clip and an electronic ignitor for igniting fuel which flows into the mantle. The mantle is surrounded by a globe, and a wire guard surrounds the globe. A ventilator cap is removably attached to the burner assembly and to the wire guard so that the cap, wire guard, and globe can be removed as a unit from the burner assembly. A nut is rotatably captured on the ventilator cap for attaching the ventilator cap to the burner assembly. The fuel tank includes a wide, molded base which provides stable support. An air pump for the fuel tank includes a check valve which automatically opens and closes as air is pumped and a pressure indicator to indicate when the fuel tank reaches operating pressure. The pump is automatically lubricated on each stroke.
