Specification forming part of Design No. 27,968, dated December 7, 1897.
Application filed October 21, 1897. Serial No. 656,583. 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 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 a prism-light, which is comparatively thin and substantially flat. B B are prisms on one side thereof.
     C are lines formed on one side of the prism-light and covering a portion of its surface.
    The essential features of my design are found in a prism-light having a substantially flat and relatively thin body with prisms parallel to each other and extending across one side and on the other side a series of ornamental line or ridges with flat tops formed on the surface, so as to project above the same and divide such surface into a series of small surface areas.
    I claim--
    A design for a prism-light, substantially as shown and described.
JOHN MEIGGS EWEN.
