SPECIFICATION forming part of Design No. 27,975, dated December 7, 1897.
Application filed November 1, 1897. Serial No. 657,102. Term of patent 14 years.
To all whom it may concern:
    Be it known that I, FRANK C. SOPER, 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 the prism-light; B, one side thereof; C C, a series of prisms on the opposite side, and D a series of lines crossing and interrupting the prisms and on the prism side arranged so as to form a figure or pattern.
    The essential features of my design are found in a prism-light comprising a substantially flat and thin body with a series of prisms on one side and a series of lines produced on the body of the prism-light on the prism side and crossing or interrupting the prisms, such lines arranged so as to form a figure or pattern.
    I claim--
    A design for a prism-light, substantially as shown and described.
FRANK C. SOPER.
