SPECIFICATION forming part of Letters Patent No. 339,425, dated April 6, 1886.
Application filed February 16, 1884. Serial No. 120,084. (No model.)
To all whom it may concern:
    Be it known that I, JACOB JACOBS, of New York city, in the county of New York, and in the State of New York, have invented certain new and useful Improvements in Illuminating-Tiles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which--
    Figure 1 is a perspective view of the upper side of my tile separated from its supporting frame. Fig. 2 is a like view of the lower side of the same. Figs. 3 and 4 are respectively perspective views of the upper and lower sides of my illuminating-lens, and Fig. 5 is a section of said tile upon line x x of Figs. 1 and 2.
    Letters of like name and kind refer to like parts in each of the figures.
    Heretofore illuminating-tiles have been constructed with recessed cast-metal frames, upon and within which were placed illuminating-lenses, and the space around said lenses and within the recessed upper side of said frames then filled with cement or other like material made plastic; but for such construction a special pattern is required for each size and shape of opening, and it is frequently the case that much trouble and expense are caused by the delay necessary while procuring a casting, more especially when a new pattern must be made.
    The design of my invention is to enable illuminating-tiles to be easily, quickly, and cheaply constructed at any point where an ordinary blacksmith can be had or where working in wire is done; and to this end said invention consists, principally, in an illuminating-tile composed of a metal bottom web constructed from interwoven wire or rods with openings for the reception of the lower ends of glass lenses, in combination with lenses which fit into said openings, and are each provided with a horizontal flange that extends over and tests upon the upper side of said web, and with cement, which fills the space between and around said lenses, substantially as and for the purpose hereinafter specified.
    It consists, further, in a vault or area cover composed of a supporting-frame and one or more tiles, winch are fitted into or rest upon the same, and are each composed of an interwoven
web of wire or rods having light-openings of predetermined size and relative arrangement, glass lenses which are adapted to fit into and extend through said openings, and are each provided with a radial flange that extends-over and rests upon the upper side of said web, and cement which fits the space between and around the upper portions of said lenses, substantially as and for the purpose hereinafter specified.
    In the construction of my tiles, I first form a metal web, A, from wire or small rods which are woven together so as to form meshes or openings a, that have any predetermined size and shape, and have such relative arrangement as will best adapt the tile to the intended location and use. Said openings are preferably square, but may have any form which can be produced by weaving together wires.
    The webbing A may be constructed in place within a supporting-frame, B, in which event the wires or rods would be secured to or pass around some suitable portion of said frame, or it may be constructed separately and its edge be formed of a bar of iron, A', but into the desired form, and having each wire or rod passed around or otherwise secured to the same. The bottom web, A, is now placed horizontally upon a suitable support, and into each light-opening a is inserted the lower end, c, of a glass lens, C, which end is adapted to loosely fill said opening. At a suitable point each of said lenses is provided with a radial flange, c', which extends over and rests upon the upper side of said web. In case of the use of square lenses, as preferred, said flanges c' would meet, and thus cover the entire upper surface of said web. After the lenses C are in place the space between and around their upper portions is filled with plastic cement and the same permitted to harden thoroughly before the tile is used. Said tile thus constructed possesses all required strength and durability, and can be constructed for a much less cost than is necessary for the production of illuminating-tiles of usual construction.
    Having thus fully set forth the nature and merits of my invention, what I claim as new is--
    1. An illuminating-tile composed of a metal bottom web constructed from interwoven wire or rods with openings for the reception of the
