and by any of the constructions of iron set forth in my patents for the same.     The paper-board material or artificial wood made use of in my new constructions is made according to one process or method of manufacture of paper-- pulp, glue, and bichromate of potash, with the addition in some cases of alum and soluble glass. The composition thus made is formed into sheets under pressure, thinner than the final thickness of board or manufacture required, the ultimate thickness being obtained by coating two or more of such sheets with a solution of glue and bichromate of potash placed with their faces together, and then passed between pressure-rollers, when the case admits of the application of such pressure, and in other cases placed in suitable molds from which the air can be withdrawn while pressure is applied, as when the board material is shaped into raised and sunken surfaces, or into curved or other shapes, as required in the manufacture of illuminating curved roofs, and in the manufacture of illuminating elevator-doors, and in the production of a button or knob surface upon the paper-board grating, the light-holes in the paper-boards being either punched out of the boards by dies, as in punching metal, or formed in the same by molding or molding and pressure. When the grating is made of two layers of paper-board the rabbeted seats for the glasses are formed by making holes of smaller diameter in the bottom board or layer than the ones made in the top layer or board, as will appear by the accompanying drawings illustrating my invention, in which--     Figure 1 represents a paper-board formed with light-holes in plan and cross-section for the bottom of the grating, with a portion of the same completed by the addition of the top layer of paper-board made with holes large enough to take in the glasses. Fig. 2 represents in plan and cross-section the top perforated paper-board. Fig. 3 represents in cross-section a completed paper-board grating partly set with glasses. Figs. 4 to 10 represent some of the shapes in which I propose to employ the artificial wood in patent light work. Fig. 4 represents a curved illuminating grating-tile made of artificial wood or paper-board material of the character designed to make rear-extension roofs. Figs. 5, 6, and 7 represent glasses inclosed in mounts made of artificial wood or paper-board material, a single glass in each mount. Figs. 8, 9, and 10 represent clusters of glasses set in mounts, such mounts being called "quarries" or "hand-size" illuminating grating-tiles. Fig. 9 represents the illuminating grating-tile or quarry made of marbleized paper-board. Fig. 11 represents a pair of illuminating elevator-doors made of artificial wood or paper-board material; Fig. 12, a cross-section of Fig. 11 on the line x x. Fig. 13 represents an illuminating corrugated grating-tile, made of artificial wood or paper-board material, designed for making curved and

other forms of illuminating rear-extension roofs; Fig. 14, a cross-section of Fig. 13 on the line y y.     A represents the bottom perforated paper-board of an illuminating paper-board grating-tile or vault-cover. B represents the top perforated paper-board; a a, light holes or perforations in the bottom board; b b, light holes or perforations in the top board; c c, buttons on the surface of the top board; C, illuminating-glasses; D, hexagonal-shaped mount made of artificial wood or paper-board; E, lozenge-shaped mount made of same; F, circular shaped, made of same; G, lozenge-shaped quarry or hand-size illuminating-grating made of artificial wood or paper-board; H, hexagonal-shaped quarry or hand-size illuminating-grating made of artificial wood or paper-board; I, hexagonal-shaped quarry or hand-size illuminating-grating made of marbleized artificial wood or paper-board; J, frame of illuminating elevator-doors; K K, illuminating elevator-doors made of artificial wood or paper-board; L M, corrugations of illuminating grating-tile made of artificial wood or paper-board.     I have represented the elevator-doors and the grating-tiles for roofing and roof-paving purposes as manufactured from layers of paper-boards. The corrugated illuminating-tile and the mounts and quarries are represented as made of paper-pulp material made according to the Bodine or the Carmichael methods or processes, or equivalent methods of employing fibers of straw, jute, or other suitable fiber. The glasses may be fixed in these paper-board or artificial-wood tiles, quarries, and mounts by means of coal-tar-sulphur cement or otherwise; and the illuminating-shingles may be flat, instead of corrugated.     The knobs or buttons upon the surface of the pavement-tiles I prefer to make of the same material as the body of the tile or vault-cover itself is composed of; the buttons being molded with the molding of the artificial wood or paper-board; but metal buttons may be also employed.     The elevator-doors are made thick enough for strength; or a metal frame of wrought-iron may be combined with the construction, if found desirable.     What I claim as my invention, and desire to secure by Letters Patent, is--     1. Illuminating vault-covers or grating-tiles and surfaces made of them when the same are made by combining glasses with artificial wood or fibered material consolidated or brought into the form of paper-board material, and shaped into grating-tiles, shingles, mounts, and quarries, substantially as and for the purposes herein set forth and illustrated.     2. Illuminating vault-covers or grating-tiles, shingles, mounts, and quarries, and surfaces made of them when the same are made by combining glasses with marbleized paper-boards,
