Specification forming part of Design No. 27,678, dated September 21, 1897. Application filed August 5, 1897. Serial No. 647,266. Term of patent 14 years.

To all whom it may concern:     Be it known that I, JOHN MEIGGS EWEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented and produced a new and original ornamental Design for Prism-Lights, of which the following is a specification.     My invention relates to designs 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 section therethrough.     Like letters indicate like parts in the two figures.     The prism-light A consists of a body of glass or the like bounded by the straight edge B and two curved edges C in the form of compound curves. One surface of the prism-light

is substantially smooth or plain, the other side being provided with a series of prisms extending across the light.     I have shown certain angles, arrangements, and numbers of the prisms, but the essential feature of my invention is a body of glass having one straight edge and two curved edges, the curved edges being in the form of compound curves, the glass being provided on one side with a series of prisms extending thereacross.     I claim--     A design for a prism-light as herein shown and described.
