SPECIFICATION forming part of Design No. 29,809, dated December 13, 1898.
Application filed August 15, 1898. Serial No. 688,632. Term of patent 7 years.
To all whom it may concern:
    Be it known that I, GEORGE K. CUMMINGS, a citizen of the United States, residing at New York, in the county and State of New York, have invented and produced a new and useful Design for Prism-Windows, of which the following is a specification.
    My invention relates to a new design for prism-windows, and is illustrated in the accompanying drawings, in which—
    Figure 1 is an elevation or front view of a prism-window embodying my said design, and Fig. 2 is a vertical cross-section through the window of the window.
    The design consists of a window comprising a number of triangularly-shaped panes or
lights of prism-glass arranged as shown. The parallel cross-lines of Fig. 1 represent the angular edges of the glass prisms. The heavier doubled lines of the drawings represent the framework.
    I claim—
    The design for a prism-window as herein shown and described.
    In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
GEORGE K. CUMMINGS.
