mount. The sides of the glass are preferably fluted or roughened, and before the melted brimstone is put around the glass I prefer to paint the sides of the glasses with coal-tar to make the bond between the glass and brimstone complete. Glasses thus treated are capable of withstanding the destructive effects of plastic concrete during its process of induration, notwithstanding the fact that such mounts are hard, unyielding, and inelastic, the cause of the breakage of the glasses of concrete lights not being for the want of some soft, yielding, and elastic substance "interposed between glass and concrete," as some erroneously imagine.     What I claim as my invention, and desire to secure by Letters Patent, is--     1. Illuminating-surfaces made of vault-covers or grating-tiles, in which the distance between the rows of glasses at the junction edges of the tiles is the same as the distance between any two rows of glasses in the body of the tile, when such tiles are combined with supports formed with lightways produced by fluting the sides of the supports, or by means of lugs upon the sides of the supports, substantially as and for the purposes herein set forth and illustrated.     2. Illuminating-surfaces made of vault-covers or grating-tiles of lozenge and sections of lozenge shape, in which the distance between the rows of glasses at the junction edges of the tiles is the same as the distance between any two rows of glasses in the body of the tile, when such tiles are combined with supports formed with lightways produced by fluting the sides of the supports, or by means of lugs upon the sides of the supports, substantially as and for the purposes herein set forth and illustrated.     3. Foundation-frames made with X or duplex cross-bars for supporting illuminating-tiles in combination with the same, substantially as and for the purposes herein set forth and illustrated.     4. Cast-iron X or duplex rafters or supports for the construction of roofs and roof-pavements, in combination with illuminating vault-covers or grating-tiles, substantially as and for the purposes herein set forth and illustrated.     5. Foundation-frames with recessed borders inlaid with tesseræ or "geometrical tiles," or with concrete, in either plain or ornamental design shapes, in combination with illuminating monomorphous surfaces, substantially as and for the purposes herein set forth and illustrated.     6. Illuminating monomorphous surfaces combined with tessellated or ornamental border, substantially as and for the purposes herein set forth and illustrated.

7. Illuminating concrete surfaces formed of sunk-surface vault-covers or grating-tiles combined in loco-- that is to say, at the building or place of permanency where the construction is to be a fixture-- and there completed and rendered monomorphous by a continuous concrete surface, substantially as and for the purposes herein set forth and illustrated.     8. Molded and hardened concrete or stone gratings and metal gratings or plates, made with a facing of molded and hardened concrete, formed with rabbeted seats, in part or entirely concrete, for the reception of glasses, and setting the glasses therein by means of coal-tar-sulphur cement, substantially as and for the purposes herein set forth and illustrated.     9. Illuminating concrete and concreted vault-covers or grating-tiles in which the glasses as to their lower sections are fixed by means of coal-tar-sulphur cement, and as to their upper sections are surrounded by a band or ring of brimstone, substantially as and for the purposes herein set forth and illustrated.     10. The mode or process of making concrete lights illustrated by Figs. 10, 10a, l0b, and 10c, as herein set forth and described.     11. Durable glass illuminating vault-covers and grating-tiles in which the glasses are fixed by means of concrete or Portland cement on the covered-joint method, substantially as and for the purposes herein set forth and illustrated.      12. Concrete lights made by combining glasses with concrete in either its plastic state or in a molded and hardened state, the glasses having previously been inclosed in mounts composed of coal-tar-sulphur cement, substantially as and for the purposes herein set forth and illustrated.     13. Concrete lights made by combining glasses with concrete in either its plastic state or in a molded and hardened state, the glasses having been previously inclosed in mounts made by pouring the brimstone in melted state around the glasses, (as in lead-belting glasses,) substantially as and for the purposes herein set forth and illustrated.     14. Stone or concrete lights made with a strengthening-core of metal cast in the form of rings for seating the glasses, the rings being held to each other by connecting bands or bars, that leave open spaces for the concrete to pass through, and thus form the whole or a portion of the under face of the grating or plate, as represented at T T, Figs. 10c and 11, substantially as and for the purposes herein set forth and illustrated.
