Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
113 words
An apparatus for heating spectacle frames comprising a housing, a thermally insulated heating chamber enclosed by said housing and having an access opening in the wall of said housing, closing means normally closing said access opening, electrical heating means in said chamber for heating the interior thereof a spectacle frame supporting element mounted on said closing means, and electrically actuated means for moving said closing means between a first position wherein said element is positioned exteriorly of said chamber and a second position wherein said element is positioned within said chamber, said element being movable only in a horizontal plane whereby a spectacle frame will remain thereon during movement of said closing means.
Claim 2
Independent Claim
113 words
An apparatus for heating spectacle frames comprising a housing, a thermally insulated heating chamber enclosed by said housing and having an access opening in the wall of said housing, closing means normally closing said access opening, electrical heating means in said chamber for heating the interior thereof a spectacle frame supporting element mounted on said closing means, and electrically actuated means for moving said closing means between a first position wherein said element is positioned exteriorly of said chamber and a second position wherein said element is positioned within said chamber, said element being movable only in a horizontal plane whereby a spectacle frame will remain thereon during movement of said closing means.
