Abstract

303,620. Dunand, E. L. Nov. 23, 1927. Shade galleries and holders; mounting shades directly on rods or tubes. - The helical spring which engages an electric lamp bulb in order to secure the shade on the lamp holder is permanently secured to the shade, is of parallel form and is also formed with an adjustable mouth to suit bulbs of different sizes. The spring 5 may be soldered or otherwise secured to the base ring or to an auxiliary base ring of the shade, or, as shown, may be formed integral with the base ring 1. Fig. 3 shows a two-part adjustable mouth formed by separate elements 6, 8. The mouth elements may however be integral with the spring and there may be more than two of them.
