Patents: 474 of 530	UNITED STATES PATENT OFFICE GEORGE K. CUMMINGS, NEW YORK, N. Y. DESIGN FOR A PRISM-WINDOW.	George K. Cummings 6 of 8
SPECIFICATION forming part of Design No. 29,808, dated December 13, 1898. Application filed August 15, 1898. Serial No. 688,630. 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 transverse cross-section through the window of the window.     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: Within a rectangular parallelogram appears a row of oval or elliptical figures, each overlapping upon its neighbor on either hand and inclosing a diamond-shaped prism-light whose sides curve inwardly, four elongated elliptical prism-lights and four that are somewhat shield-shaped. At the top, bottom, and sides of the design appear prism-lights of triangular and diamond-like shape.     The design presents the general appearance of a row of overlapping ovals with central diamonds.     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. Witnesses:     EDWIN SEGER,     SIDNEY MANN.
