Abstract
Abstract A lighted beverage glass having a stem with a central bore extending therethrough. A cup-shaped glass mounting portion is provided at the top of the stem and has a glass shell member removably mounted therein. A plurality of horizontally extending gripping ribs are provided on the mounting portion to securely retain the glass therein. An annular shoulder is formed at the top portion of the central bore. A light assembly is mounted in the central bore of the stem for directing light through the bottom of the glass. The light assembly includes an electric bulb, a dry cell battery and a spring member mounted between the bulb and the battery. The annular shoulder serves as a seat for the electric bulb.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
254 words
A lighted beverage glass comprising: a stem means having a base portion and a stem portion fastened to the base portion, said stem means having a central bore extending therethrough, said stem portion having a cup-shaped glass mounting portion at the upper end thereof, said cupshaped glass mounting portion including a planar bottom wall, an upstanding, annular side wall made of a flexible material and extending substantially perpendicularly from said bottom wall, and a plurality of gripping ribs projecting laterally inwardly from the inner face of said side wall closely adjacent the top edge thereof, said ribs adapted to make tight contact with the outer surface of a glass adjacent the bottom thereof and thereby securely retain the glass in said cup-shaped glass mounting portion; a glass removably mounted in said cup-shaped glass mounting portion; a light assembly mounted in said central bore of said stem means for directing light through the bottom of said glass, said light assembly including an electric incandescent bulb, a dry cell battery, a spring mounted between said bulb and said battery, and means for selectively establishing electrical contact between said bulb and said battery to thereby establish an electrical current path for energizing said bulb; and an annular shoulder formed in said stem means at the top portion of said central bore to serve as a seat for said bulb with the top portion of said bulb projecting slightly past said shoulder, said spring biasing said bulb against said seat to thereby reduce the possibility of bulb breakage.

Claim 3
Dependent Claim
111 words
A lighted beverage glass according to claim 1 wherein said light assembly includes a metallic cradle member for holding said battery located inside said central bore, said cradle member having a body portion and a pair of contact flanges which are located on the opposite ends of said body and between which said battery is held, said spring bearing against the upper one of said cradle member flanges, and a switch knob threaded into a threaded portion formed in said base for supporting the lower one of said cradle member flanges and adapted for manual rotation to move said battery into contact with said bulb against the bias of said spring.
