SPECIFICATION forming part of Design No. 26,864, dated April 6, 1897. Application filed February 9, 1897. Serial No. 622,675. Term of patent 14 years.

To all whom it may concern:     Be it known that I, WILLIAM H. WINSLOW, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Design for Ornamental Prism-Plates for Windows, of which the following is a description.     My invention relates to a new design for ornamental prism-plates for windows and is illustrated in the accompanying drawings, wherein--     Figure 1 is a face view of a portion of a prism-plate embodying my design. Fig. 2 is a section.     Like letters refer to like parts throughout both figures.     The design consists of a series of prismatic light A A, provided each with the substantially parallel projecting prisms B B, separated by grooves or indentations C C. A number of these prism-lights are placed near

together, being separated by thin strips D D' or opaque material. The opaque strips D', which are placed substantially at right angles to the projecting prisms, by thin strips are provided with the enlargements D², sad enlargements being located at the intervals along their lengths and in the grooves or indentations between the prisms.     The essential feature of my design is the series of prism-lights provided with substantially parallel projecting prisms separated by thin strips of opaque material, as shown.     I claim--     The design for ornamental prism-plates for windows, substantially as shown and described.     In testimony whereof I affix my signature, in the presence of two witnesses, this 22d day of April, 1896. WILLIAM H. WINSLOW. Witnesses:     FRANCIS W. PARKER,     DONALD M. CARTER.
