Abstract

441,288. Lamp shades. COLLIER, W. H., 71, Morris Road, Washwood Heath, Birmingham. July 20, 1934, No. 21256. [Class 75 (ii)] In a lampshade, radial ribs 6 which support the fabric or other material of the shade, or plates of the material itself when it is rigid, are pivoted on horizontal axes 5 at or near to their inner ends to a supporting ring 4 or bracket mounted above the light source 1, and upward or downward extensions 7 of the ribs engage with spiral slots in the face of a disc 11, which is rotatable with respect to the supporting ring 4 to vary the angle between the ribs and the centre axis of the lamp. The disc is adjustably connected to the ring 4 by a member 9 and the upper part of the frame 3. The extensions 7 may pass through radial slots in a second disc secured to the top of the frame 3.
