Abstract
683,746. Lampshades. BARBER, G. March 9, 1951, No. 5762/51. Class 75(ii) A lampshade comprises one or more panels of pliable non-inflammable thermoplastic material such as polyvinyl chloride welded together at their edges to produce an open ended sleeve which is applied to a rigid frame composed of upper and lower rings connected by stays. The ends of the sleeve may be stitched to the rings. The sleeve material may be processed to simulate plain or patterned silk.
