SPECIFICATION forming part of Design No. 27,335, dated July 13, 1897. Application filed June 15, 1897. Serial No. 640,932. Term of patent 14 years.

To all whom it may concern:     Be it known that I, JOHN M. 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 a new design for prism-lights and is illustrated in the accompanying drawings, wherein--     Figure 1 is a perspective view, and Fig. 2 a section through a prism-light containing my design.     Like parts are indicated by the same letter in each figure.     A is the elliptical or oval body; B B, the prisms thereon.

I have shown a certain thickness of the prism-light, and certain inclination of the angles of the prisms, and proportions of the diameters of the ellipse; but the essential features of my invention are found in a prism-light having a body of a substantially elliptical or oval shape with prisms thereon substantiality parallel with the long axis of the ellipse.     I claim--     The design for a prism-light substantially as shown and described. JOHN M. EWEN. Witnesses:     DONALD M. CARTER,     HOMER L. KRAFT
