Claims
- 1. A radiant type heater for heating an opthalmic frame having a frontal lens holding portion and a temple portion comprising a housing, electrical heating means and heat transfer means for transferring heat to first and second opposed heat radiating surfaces on said housing for receiving said frontal lens holding portion therebetween, said first heat radiating surface having opposite extreme outer ends with at least one extreme outer end being of a configuration to extend radiation beyond said one extreme outer end to meet radiation from said second heat radiating surface, said first heat radiating surface being of a dimension to permit said temple portions to be placed outside of said extreme outer ends of said first heat radiating surface and to also permit a portion of said frontal lens holding portion to be placed outside of said one extreme outer end of said first heat radiating surface, whereby said one extreme outer end will heat said portion of said frontal lens holding portion which extends beyond said one extreme outer end of said first radiating surface.
- 2. A radiant type heater as set forth in claim 1 wherein said first radiating surface is shorter than said second radiating surface.
- 3. A radiant type heater as set forth in claim 1 wherein said first and second radiating surface are of equal length, each having at least one extreme outer end portion formed to extend radiation beyond said extreme outer end portions, said radiation from each meeting and crossing in an oblique manner.
- 4. A radiant type heater as set forth in claim 1 wherein said second radiating surface has a concave radiating surface and said first radiating surface has a convex radiating surface, with said convex and concave surfaces facing each other to compliment the radiation of each other on said article.
