SPECIFICATION forming part of Design No. 27,981, dated December 7, 1897.
Application filed October 4, 1897. Serial No. 654,091. Term of patent 14 years.
To all whom it may concern:
    Be it known that I, FRANK L. WRIGHT, 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 where they consist substantially of a flat body with prisms on one side and an ornamental design on the other.
    My invention is illustrated in the accompanying drawings, wherein--
    Figure 1 is a plan view of the ornamental side of the prism-light. Fig. 2 is a cross-section therethrough on line 2 2.
    A is the body of the prism-light; B, a series
of lines formed on the surface and associated together so as to make a pattern, such pattern serving as a border to a central field. The shape of the raised line is shown in cross-section.
    The essential features of my design are found in a prism-light having an ornamental border on the back of the body provided with prisms on the other side.
    I claim--
    A design for a prism-light, substantially as shown and described.
FRANK L. WRIGHT.
