SPECIFICATION forming part of Design No. 27,974, dated December 7, 1897. Application filed November 1, 1897. Serial No. 657,101. Term of patent 14 years.

To all whom it may concern:     Be it known that I, FRANK C. SOPER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and original Design for Prism-Lights, of which the following is a specification.     My invention relates to designs for prism-lights.     Figure 1 is a plan view of a prism-light embodying my design. Fig. 2 is a cross-section therethrough.     A is the body of the prism-light; B, one side thereof; C C, a series of prisms on the opposite side of a certain side or depth; D D, a series of other prisms of a less size or depth. These prisms of different sizes or depths are

arranged with reference to each other on the prism side of the plate so as to form a figure or pattern.     The essential features of my design are found in a prism-light comprising a substantially flat body with prisms thereon, the prisms on one side being of different sizes or depths and arranged so as to form figures or patterns.     I claim--     A design for a prism-light, substantially as shown and described. FRANK C. SOPER. Witnesses:     JEAN ELLIOTT,     HOMER L. KRAFT.
