ABSTRACT:
A glass globe for the purpose of preventing insects from blocking out the source of light in a portable lantern has two prearranged doors. The doors cover approximately 30 to 40% of the surface area of the globe and are made of a fire resistant material with a light reflective surface. The doors open back to back from the same hinge area and are biased by springs circumscribing their hinge rod assemblies. The doors, when open, prevent the wind from blowing out the lantern flame and yet permit bugs and insects to enter to the inside area of the glass globe whereby they become burned and liquidated. The doors are mounted within a fire proof frame and made of a polished metal material so as to give light reflection and reduce the light loss from the light source. The glass globe is made of various sizes to replace the various size globes in the conventional commercial portable lanterns. The doors are mounted on a hinge rod and biased by helical springs circumscribing the rod. The rods are anchored in flanges on the door frames and pass through sleeves on the face of the doors. There are latches on each door that connect to a pin in the frame for enabling the doors to be closed against the tension of the springs. The door frame engages the glass globe by means of recesses in the frame.
