SPECIFICATION forming part of Design No. 27,328, dated July 13, 1897. Application filed June 15, 1897. Serial No. 640,943. Term of patent 14 years.

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 through the prism-light shown in Fig. 1.     As illustrated in the drawings, the prism-light A is provided with the edges B and C, formed of compound curves, which unite so as to form the projections or points D and E.

The light has a series of projecting ribs or prisms F extending across its face. Certain angles and dimensions of the prisms and curvatures of the edges are shown; but the essential features of my design are found in a prism-light provided with the edges B and C, formed of compound curves and having a series of prisms extended across its face.     I claim--     The design for a prism-light herein shown and described. HENRY F. BELCHER. Witnesses:     DONALD M. CARTER,     HOMER. L. KRAFT.
