SPECIFICATION forming part of Design No. 27,988, dated December 7, 1897.
Application filed October 23, 1897. Serial No. 656,231. 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 description.
    My invention relates to a design for prism-lights.
    Figure 1 is a plan view of a light embodying my design. Fig. 2 is a section therethrough.
    A is the body of the prism-light; B B, a series of prisms on one side thereof; C C, a series of dots, lines, or portions of lines on the other side. These dots and portions of lines
are arranged and related so as to produce a design on the prism-light, formed as it were, of broken, fragmentary, or interrupted lines.
    The essential features of my design are found in a prism-light having a substantially flat body with a series of prisms on one side and on the other a series of broken, interrupted, or fragmentary lines or forms arranged so as to produce a unitary pattern.
    I claim--
    A design for a prism-light, substantially as shown and described.
FRANK L. WRIGHT.
