SPECIFICATION forming part of Design No. 29,810, dated December 13, 1898.
Application filed August 15, 1898. Serial No. 688,633. 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 on a line a little to the left of the middle of the window, as shown in Fig. 1.
    The design consists of a number of variously-shaped panes, plates, or lights of prism-glass grouped together so as to form a single window or design.
    The parallel cross-lines of the drawings represent the angular edges of the glass prisms which, with a body portion of glass, constitute the said panes, plates, or lights.
The heavier doubled lines of the drawings represent the framework.
    The design is described as follows: Three rows of arched prism-lights arranged side by side and breaking joints occupy the lower portion of a rectangular parallelogram, the upper portion of which is divided by vertical lines and thereby equally spaced into prism-lights which are substantially parallelograms, though pointed at their lower ends, as shown.
    The design as a whole presents the appearance of an ornamental grating provided with prism-lights.
    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.
