Abstract

394,854. Lamp brackets and stands. GRAHAM, R. H., 52, Warren Street, and HORSLEY, W. N., 16, Shakespeare Road, both in Fleetwood, Lancashire. Oct. 11, 1932, No. 28294. [Class 52 (v).] In an adjustable support for an electric lamp, ball-ended arms 2 are inserted between a base 7, having a ballended projection 8, and a ball-ended arm 1 screwed into the lampholder with an interposed washer 11, each pair of adjacent ball ends being adjustably connected by clamping plates 4. A clip or a wall plate having a ball end may be used instead of the base 7.
