Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 165 words
Apparatus for heating a specific area of a thermoplastic frame for glasses comprising: a. a housing having an air discharge passageway therein, b. a deflector baffle mounted at one end adjacent one side of said discharge passageway and inclined inwardly and laterally thereover with an intermediate portion of said baffle curved laterally over and in spaced relation to said discharge passageway with the other end of said deflector baffle directed toward and terminating beyond and in spaced relation to the other side of said discharge passageway leaving a space therebetween for receiving a specific area of the frame to be heated, and c. means delivering heated air to said discharge passageway so that heated air passes adjacent the inner surface of said deflector baffle and all the way around said specific area of the frame to be heated, said deflector baffle being substantially of a width to span the nose bridge of said frame so that the heated air passes substantially around said specific area.
Claim 2
Dependent Claim 165 words
Apparatus for heating a specific area of a thermoplastic frame for glasses comprising: a. a housing having an air discharge passageway therein, b. a deflector baffle mounted at one end adjacent one side of said discharge passageway and inclined inwardly and laterally thereover with an intermediate portion of said baffle curved laterally over and in spaced relation to said discharge passageway with the other end of said deflector baffle directed toward and terminating beyond and in spaced relation to the other side of said discharge passageway leaving a space therebetween for receiving a specific area of the frame to be heated, and c. means delivering heated air to said discharge passageway so that heated air passes adjacent the inner surface of said deflector baffle and all the way around said specific area of the frame to be heated, said deflector baffle being substantially of a width to span the nose bridge of said frame so that the heated air passes substantially around said specific area.
Claim 3
Dependent Claim 53 words
Apparatus for heating a specific area of a thermoplastic frame for glasses as defined in claim 1 in which a continuous inwardly extending flange is provided at each side of said deflector baffle in position to restrain lateral movement of the heated air as it passes adjacent the inner surface of said baffle.
Claim 4
Dependent Claim 33 words
Apparatus for heating a specific area of a thermoplastic frame for glasses as defined in claim 1 in which said housing is provided with a tapered portion which terminates in said discharge passageway.
Claim 5
Dependent Claim 45 words
Apparatus for heating a specific area of a thermoplastic frame for glasses as defined in claim 1 in which the means delivering heated air comprises: a. a blower mounted in said housing, and b. a heating element mounted between said blower and said discharge passageway.
Claim 6
Dependent Claim 33 words
Apparatus for heating a specific area of a thermoplastic frame as defined in claim 1 in which said deflector baffle is pivotally connected to said housing adjacent one side of said discharge passageway.
Claim 7
Dependent Claim 54 words
Apparatus for heating a specific area of a thermoplastic frame as defined in claim 5 in which an electrical switch element is operatively connected to said deflector baffle and to said means delivering heated air and is operable to interrupt the supply of heated air upon movement of said deflector baffle to inoperative position.
