Abstract
Abstract A fluorescent lantern supports a pair of fluorescent tubes for vertical sliding movement so that the tubes can be replaced simply by removing the cover of the lantern and withdrawing the tubes. Each of the fluorescent tubes is supported in a socket in the base of the lantern and extends upwardly through an opening in the top of the lantern. The cover is removably attached to the top by tabs so that the cover can be removed by rotating and lifting the cover. When the cover is removed, the fluorescent tubes can be withdrawn upwardly through the openings in the top. The base includes a battery compartment for a battery power source, and the battery compartment is closed by a battery cover which is removably attached to the base by tabs so that the cover can be removed by rotating and withdrawing the cover.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
142 words
A fluorescent lantern comprising: a base for supporting the lantern, a globe above the base, a top above the globe, a cover removably attached to the top, a fluorescent tube extending through the globe between the base and the top, the fluorescent tube having a lower end supported by the base and an upper end which extends through an opening in the top, electrical contact means in the base for connecting an electric circuit to the lower end of the fluorescent tube, electrical contact means in the cover for connecting an electric circuit to the upper end of the fluorescent tube, the fluorescent tube being slidably mounted within the opening in the top whereby the fluorescent tube can be removed from the lantern by removing the cover from the top and withdrawing the fluorescent tube upwardly through the opening in the top.
Claim 2
Dependent Claim
142 words
A fluorescent lantern comprising: a base for supporting the lantern, a globe above the base, a top above the globe, a cover removably attached to the top, a fluorescent tube extending through the globe between the base and the top, the fluorescent tube having a lower end supported by the base and an upper end which extends through an opening in the top, electrical contact means in the base for connecting an electric circuit to the lower end of the fluorescent tube, electrical contact means in the cover for connecting an electric circuit to the upper end of the fluorescent tube, the fluorescent tube being slidably mounted within the opening in the top whereby the fluorescent tube can be removed from the lantern by removing the cover from the top and withdrawing the fluorescent tube upwardly through the opening in the top.
