Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
106 words
A method of manufacturing a sealed beam lamp which comprises: providing an outer envelope including a reflector, providing a transparent front glass, providing a quartz halogen lamp disposed within said envelope, providing an elongated member for supporting the halogen lamp relative to the envelope, positioning said elongated member relative to said reflector, passing current through the elongated member sufficient to raise the temperature, thereof and facilitate permanent deformation; align deforming the elongated member to the said halogen lamp relative to said reflector thereafter moving said elongated member relative to said reflector to a second position for joining and then joining said reflector to said elongated member.
Claim 2
Independent Claim
106 words

Claim 3
Dependent Claim
13 words
The method as described in claim 1 wherein said elongated member is crank-shaped.
Claim 4
Dependent Claim
37 words
The method as described in claim 2 wherein said reflector has a center line and said method includes the step after said deforming step of moving said reflector in a direction parallel to the center line thereof.
