SPECIFICATION forming part of Design No. 26,829, dated March 30, 1897.
Application filed February 9, 1897. Serial No. 622,673. Term of patent 14 years.
To all whom it may concern:
    Be it known that I, OLIN H. BASQUIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Design for Prismatic Window-Lights, of which the following is a specification.
    My invention relates to a new and improved design for window-glass, and is illustrated in the accompanying drawings, wherein--
    Figure 1 is a face view of a section of window-glass embodying my design. Fig. 2 is a cross-section through the same.
    My design consists of a sheet or section A, of glass for windows or the like, provided on one face with the projecting ribs B, separated by grooves or indentations C. The projecting ribs B are rounded at the edges, as shown,
the outer edge of each rib presenting a curved surface.
    I do not limit myself to any particular number of projections on a given plate, as the number may be varied at will.
    The essential feature of my design is the section or plate provided on one side with the projections separated by grooves or indentations, the outer edges of the projections being rounded, so as to present a curved surface.
    I claim--
    The design for a window-glass as herein shown and described.
OLIN H. BASQUIN.
