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.

GEORGE K. CUMMINGS. Witnesses:     EDWIN SEGER,     SIDNEY MANN.
