SPECIFICATION forming part of Letters Patent No. 276,100, dated April 17, 1883.
Application filed November 16, 1882. (No model.)
To all whom it may concern:
    Be it known that I, ELIHU VEDDER, of the city, county, and State of New York, have invented certain Improvements in Decorative Structures, of which the following is a specification.
    My invention relates to that class of ornamental structures composed of blocks or studs of vitreous or other ornamental material and supported in one plate to form a curtain sheet or panel; and it consists in the modes of forming tile supporting-frame, of forming the blocks to fit and be supported by the latter, and of making the blocks so as to secure a brilliant illuminating or decorative effect.
    In the drawings, Figure 1 is a view illustrating one construction of the frame of flat strips. Fig. 2 is a view showing the frame as made of straight wires. Fig. 3 shows tile frame of crossed and twisted wires supporting transparent, translucent, or opaque blocks. Fig. 4 is a detail view, showing a mode of uniting the crossed strips. Fig. 5 is a face view of a decorative screen or panel. Fig. 6 is a perspective view of one of the blocks. Fig. 7 is a face view of a panel with the blocks concealing the frame. Figs. 8 and 9 illustrate the manner of combining blocks of different forms. Figs. 10, 11, and 12 are views illustrating a mode of making the blocks. Fig. 13 shows a mode of applying my invention.
    My invention relates, first, to the frame-work or foundation; second, to the construction of the studs or blocks for attachment to the foundation; and, third, to the construction of studs with the view of securing a brilliant illuminating effect.
    In place of making the foundation of a sheet of material perforated for the insertion of the studs, I construct it of separate wires or strips in the form of a lattice, as shown in Fig. 1, in which flat strips a, of metal or other material, are plaited together to leave openings x, or wires may be so arranged, as in Fig. 2, or wires may be twisted together, as shown in Fig. 3, and the wires or strips may be united to form openings x at regular intervals, of uniform sizes and shapes, or at irregular intervals, and of varying sizes and shapes, according to the character of the structure to be produced. When flat strips are used they may be connected at crossing points by slitting one to
form a lip, e, Fig. 4, to fit into an opening, C, in the other, and the end strips of the lattice or frame may be held in place by bending the ends w of the cross-pieces around such end strips, as shown in Fig. 5. The strips may be of different cross-sectional forms-- round, as in Fig. 2, flat, as in Fig. 5, or otherwise-- and, being separate, the structure can be built up to any required extent by combining the strips and studs.
    The blocks or studs B may be of any desired shapes and dimensions, and with grooves i, Fig. 6, at two or more of the sides, to receive the strips or cross-pieces of the frame, such grooves being so shallow as to expose part of the frame between adjacent blocks, as shown in Fig. 5, or so deep as to wholly cover the cross-pieces, as shown in Fig. 7. In some cases, when the lattice is made of wires, blocks B' may be perforated transversely in one or both directions, to receive connecting-wires. The blocks may be of any desired ornamental configuration, solid, as in Fig. 8, or open, as at B² in Fig. 9, and may be combined with rings or smaller blocks or forms.
    It is well known that a much more brilliant effect is produced when the surface of a block through which light is transmitted is irregular, presenting different angles. For this reason such blocks have been molded and ground with irregular faces. I have found that a much more brilliant effect is produced by having a surface resulting from an irregular fracture of the glass. To secure this surface I form bars capable of being separated into sections constituting the blocks; or I mold the blocks with projections, which may be broken off without danger of fracturing the main body of the block. Thus a bar, D, Fig. 10, of glass or other frangible material, may be molded so that sections, Fig. 11, broken off, will constitute blocks of the desired shape with fractured surfaces; or blocks may be molded with projections d, full and dotted lines, Fig. 12, which are easily broken off, forming irregular faces y, which produce an intense and brilliant effect that can not be obtained by any artificial surface.
    I claim--
    1. The combination, in a decorative structure, of a lattice or frame consisting of separate strips or bars combined to form openings x, and studs of ornamental material inserted in such
