Abstract
713,378. Lamp brackets. CORDWELL, F. J., and PEPPER, B. June 22, 1953 [June 25, 1952], No. 15949/52. Class 52(5) An adjustable lamp standard comprises U-shaped pivotally connected members F<SP>1</SP> and F<SP>2</SP> pivotally connected to a base B and lampshade H respectively. The two U-shaped members F' and F<SP>2</SP> are pivotally mounted on a bolt C<SP>2</SP> passing between the two limbs of the U, the members being clamped in their adjusted position by means of curved plates D<SP>2</SP> tightened into clamping position by a wing nut on the end of the bolt. When the clamping means is loosened the members may be adjusted relative to each other or the members may be twisted helically, the limbs so twisted turning on their axis beneath the clamping plates D<SP>2</SP> so that when the bolt is tightened the members are retained in their twisted position. The shade H is formed from a blank and bent into frusto-conical form, the two .ends being secured in overlapping relation. The blank is formed with lugs R spaced sufficiently to admit the bent part of the member F<SP>2</SP> mounted on a bolt S. A stop U prevents the member F<SP>2</SP> damaging the lamp.
