its marginal openings with reinforcing flanges C², such as are shown in Figs. 9 and 10, and connect the same with strengthening ribs C³. The tile-work is thereby made stronger and will stand rougher usage. For the same purpose, the meeting edges of the plates may be rabbeted as at a' and lapped, if desired.     Having described my invention, what I claim and desire to secure by Letters Patent of the United States, is--     1. A tile-plate having light-openings surrounded by an upwardly-projecting flange upon the upper inner edge of which lenses of various shapes may be squarely seated, the upper outer edge of the flange forming a raised border or annular shoulder inclosing the lenses, substantially as set forth.     2. An illuminating-tile comprising light-openings, inwardly-rabbeted flanges around said openings, lugs upwardly-projecting from the inner upper edges of said rabbeted flanges, and lenses having recesses corresponding to said lugs, substantially as set forth.     3. The combination, in an illuminating-tile, of a perforated plate, screws cast therein or otherwise secured thereto, and concrete or cement filling, substantially as set forth.     4. The combination, in an illuminating-tile, of a plate having light-openings, upwardly-projecting flanges surrounding each of these openings, and ligaments connecting and projecting above said flanges, substantially as set forth.     5. The combination, in an illuminating-tile, of a perforated plate, screws projecting therefrom, flanges around the openings in said plate, ligaments projecting above said flanges, and filling, substantially as set forth.

6. The herein-described illuminating-tile construction comprising plates having light-openings, lenses in said openings, a bearer having parallel flanges between which the sides of said plates may be inserted and top and bottom ribs at right angles thereto, the said top rib lying below the top surface of said lenses, and cement or concrete filling wholly covering the upper side of said bearer and plates between and around the lenses whereby an even walking surface is produced, substantially as set forth.     7. The herein-described illuminating-tile construction comprising a bearer having parallel flanges and plates provided with downwardly-extending offsets at each end whereby the sides of said plates are raised so that they may be inserted between said flanges and the ends thereof be in line with the supporting parts of said bearer on the under side, substantially as set forth.     8. The herein-described illuminating-tile construction comprising a tile-plate having whole light-openings projecting outwardly and entirely overlapping similar openings in an adjoining tile-plate, substantially as set forth.     9. The combination of a tile-plate having outwardly-projecting rings or light-openings, a corresponding plate having similar reinforced openings entirely lapped over by said rings, and strengthening ribs between said reinforced openings, substantially as set forth.     In testimony whereof I have hereunto set my hand and seal. HENRY HAUSTEIN. [L. S.] In presence of--     H. P. TRICOU,     A. H. STE. MARIE.
