Abstract

200,542. Etna Lighting & Heating Co., Ltd., and Prosser, H. R. March 6, 1922. Globes, shades; globe and shade holders; mounting globes and shades on electric lamp bulbs.-A lamp globe or shade preferably formed of translucent glass or ceramic material, consists of two cones or flared formations converging towards one another and joined with a gradual curve, the cones or flared formations having no internal concave formations. In one form, as shown in Fig. 1, a globe or shade a is arranged with its part c of smallest diameter encircling the upper part of an incandescent mantle b. The globe may be held in position by a holder secured around a burner tube e and provided with a number of radial arms f having screws f<1> or spring devices at their ends for engaging the upper rim of the globe. In a second form, as shown in Fig. 3, a globe a<1> is mounted on the bulb of an electric incandescent lamp and the upper portion a<2> of the globe is smaller than the lower portion and terminates on the level of the lamp cap h.
