Specification forming part of Design No. 28,909, dated June 21, 1898. Application filed May 6, 1898. Serial No. 679,962. Term of patent 3½ years.

To all whom it may concern:     Be it known that I, LOUIS J. MILLET, residing at Chicago, in the county of Cook and State of Illinois, have invented and produced a new and original Design for a Prism-Light, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof, wherein like reference-letters indicate the same or corresponding parts.     Figure 1 is a plan view of a prism-light, showing my new design. Fig. 2 is an end view of Fig. 1. Fig. 3 is a sectional view taken on line x x of Fig. 1 and viewed in the direction indicated by the arrows at the side of said figure.     As shown in the drawings, the leading and material features of my design consist of a prism-plate provided with a series of parallel

prisms A, disposed or arranged as shown in Fig. 1, and a series of prisms B, crossing the prisms A at right angles. The prisms A at their apex form an acute angle. The prisms form at their apex an obtuse angle, said prisms B being five in number and arranged or disposed two at one side of the prism-plate, two at the opposite side, and one in the center of the plate, all substantially as shown in Fig. 1.     Having described my invention, what I claim as new, and desire to secure by Letters Patent, is—     The design for a prism light as herein shown and described. LOUIS J. MILLET. Witnesses:     CHARLES S. HILL,     L. A. GARDINER.
