SPECIFICATION forming part of Design No. 27,338, dated July 13, 1897.
Application filed June 15, 1897. Serial No. 640,938. Term of patent 14 years.
To all whom it may concern:
    Be it known that I, JOHN M. EWEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented and produced a new and original Ornamental Design for Prism-Lights, of which the following is a specification.
    My invention relates to a new design for prism-lights and is illustrated in the accompanying drawings, wherein--
    Figure 1 is a plan view, and Fig. 2 a section through the same.
    Like parts are indicated by the same letter in each figure.
    A is the body, and B one of the prisms thereon.
The body is substantially pentagonal in form, and the prisms are placed on one side thereof parallel to one edge and run substantially across the same.
    The essential features of my invention are found in a prism-light comprising a body of substantially pentagonal form with a series of prisms running across one side thereof parallel with one edge.
    I claim--
    The design for a prism-light substantially as shown and described.
JOHN M. EWEN.
