ABSTRACT:
A device for supporting a plastic spectacle frame in a plastic spectacle frame warmer of the type that, in use, retains a primary amount of a solid granular material such as glass beads, in a heating pan and that uses the glass beads as a heat transfer medium, is disclosed. The device comprises a base portion for maintaining the device in a substantially upright relation within the heating pan of the frame warmer. An intermediate portion is supported by the base portion and extends upwardly therefrom. A receptacle portion is supported by the intermediate portion and extends upwardly from the base portion, and is adapted to receive and retain a secondary amount of the glass beads therein above the level of primary amount of the glass beads in the heating pan. There is provided a bridge area receiving means, preferably a pair of opposed vertically displaced slots in the receptacle portion, which slots are adapted to hold the bridge area of the spectacles in supported contacting relation with the secondary amount of glass beads. The secondary amount of glass beads is poured into the interior of the receptacle portion after the plastic frame spectacles have been placed in the slots.
