10,707. Mygatt, O. A. May 16. Globes; shades. -Glass lamp globes or shades are covered partly with double reflecting- prisms 1 on the outside, and partly with light directing or concentrating prisms 2 on the inside, these two kinds of prisms being grouped in bands or sections, as shown, in order to throw the light laterally in definite directions. The prisms are arranged approximately vertical, so that if produced they would meet at a common centre.
