To all whom it may concern:     Be it known that I, HENRY F. BELCHER, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented and produced a certain new and useful Design for Prism-Lights, of which the following is a description.     My invention relates to a new design for prism-lights, and is illustrated in the accompanying drawings, wherein--     Figure 1 is a perspective view of a prism-light embodying my design. Fig. 2 is a sectional view of Fig. 1.     As illustrated in the drawings, the prism-light A is provided with a series of projecting prisms B B, extending across its face, and is

also provided with the three edges, the edge C being straight and the edges D D being curved and having a concave outline.     Certain dimensions and angles of the lights and prisms are shown; but the essential features of my design are found in a prism-light having a series of prisms extending across its face and provided with three edges-- one straight, the other two concave.     I claim--     The design for a prism-light as herein shown and described. HENRY F. BELCHER. Witnesses:     DONALD M. CARTER,     HOMER. L. KRAFT.
