Specification forming part of Design No. 27,977, dated December 7, 1897.
Application filed October 4, 1897. Serial No. 654,088. 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.
    Figure 1 is a plan view. Fig. 2 is a cross-section on line 2 2.
    A is the body of a prism-light; B B, the prisms on one side thereof.
    B', B², B³, and B4 are lines of ornamentation produced upon the prism-light by variations in the surface-levels. These ornamental lines take the form of circles, arcs of circles,
squares, and the like, arranged concentrically about the center C and interlacing or overlapping each other. The whole forms a grid-like sort of ornament.
    The essential features of my design are found in a prism-light comprising a body with prisms on one side and on the other a series of concentrically-arranged ornamental lines which interlace or overlap each other, so as to produce a grid-like appearance.
    I claim--
    A design for a prism-light, substantially as shown and described.
FRANK L. WRIGHT.
