Estimating the term…
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.
A lantern comprising:
In a lantern having:
In a liquid fuel lantern having a fuel tank and a burner assembly connected to the fuel tank, the improvement comprising an air pump for pressurizing the fuel tank, the air pump having an elongated barrel, a pump reciprocably mounted within the barrel, and a check valve mounted in an end of the barrel for allowing pressurized air to flow out of the barrel when the pump is moved toward the check valve and for sealing said end of the barrel when the pump is not moving toward the check valve.
In a liquid fuel lantern having a fuel tank and a burner assembly connected to the fuel tank, the improvement comprising an air pump for pressurizing the fuel tank, the air pump having an elongated barrel and an elongated pump shaft reciprocably mounted within the barrel, the pump shaft having an inner end and an outer end which extends out of the barrel, a knob mounted on the outer end of the shaft for axial movement relative to the shaft between first and second positions, the outer end of the shaft projecting from the knob when the knob is in the second position, and means for biasing the knob to its first position until the pressure in the fuel tank reaches a predetermined level.
In a liquid fuel lantern having a fuel tank and a burner assembly connected to the fuel tank, the fuel tank having a generally cylindrical side wall and a bottom wall, the improvement comprising a molded base having a generally cylindrical side wall which fits snugly around the generally cylindrical side wall of the fuel tank and a bottom flange which extends outwardly from the side wall of the base.
