FRAME FOR ILLUMINATING-TILES. SPECIFICATION forming part of Letter Patent No. 501,008, dated July 4, 1893. Application filed March 13, 1893. Serial No. 465,821. (No model.)

To all whom it may concern:     Be it known that I, HENRY HAUSTEIN, a citizen of the United States, and a resident of the city and county of San Francisco, State of California, have invented new and useful Improvements in Frames for Illuminating-Tiles, of which the following is a specification.     My invention relates to vault-lights, that is to say that class of glazed covers used in sidewalks, roofs, floors, partitions, &c., for the purpose of admitting light into places situated below or near the same.     The object of my said invention is to provide an improved mode of construction for the class of devices above referred to that will make them simpler and less costly to build, lighter in bulk and yet possessed of more strength, and neater in appearance than any similar structure heretofore devised. I gain in simplicity and cheapness by doing away with some useless pieces that are wrongly considered as essential features of the frame in which the lenses are set, and which in fact tend to weaken rather than strengthen it; also by combining the reduced number of parts so they may be brought together with less work, greater ease, and dispatch. Strength and lightness are secured by the judicious assemblage of bearers or beams, bars, and rods forming a frame of a thickness varying in proportion to the strain it has to bear and within which are lodged lenses of corresponding design laid out in adjacent rows and united by cement or concrete that fills the intervening spaces. As to elegance of outline and detail, it is produced by having the glasses formed and the cement or concrete filling applied in such a manner that the supporting frame is practically hidden from view, thereby giving the tile-work a smooth and trim appearance not to be found where the frame and the unsightly cross-bars commonly employed are visible at the surface.     Referring to the accompanying drawings, in two sheets, for a detailed description of my invention,-- Figure 1 is a broken top view of my improved tile, the filling removed, and the border shown in section. Fig. 2 is a side elevation of one of the bars of increased thickness that are used at the ends of the tile-frame. Fig. 3 is an end view of the tile-frame, partly glazed as shown in Fig. 1, looking from

the lower line of the latter figure. Fig. 4 is a vertical section taken from the line x x, Fig. 1. Fig. 5 is a similar view taken from the line x y, Fig. 6. Fig. 6 is a broken top view of two tiles connected with a bearer or beam covered with filling material, showing also a border of cement or concrete. Fig. 7 is an elevation of the tiles and bearer on the line y z, Fig. 6, the border being removed, as also the flange from under the bearer. Fig. 8 is a partly-broken side elevation of the bearer and of one of the tiles supported thereby. Fig. 9 is a section of a tile of modified form, the lenses of which are tongued and grooved and self-supporting within a frame having neither longitudinal nor transversal inner bars. Fig. 10 is a plan of one of said tongued and grooved lenses. Fig. 11 is a side elevation, on a reduced scale, of the bearer or beam that forms part of my improved construction.     The same parts are indicated by the same letters of reference throughout all the views.     A represents metallic bars that are laid edgewise parallel with one another and are designed as supports for the lenses entering into the composition of my improved illuminating-tile. These bars are formed with plain rectangular sides and may vary in thickness according to how close or how far it is desired to have the various rows of glasses stand with relation to the adjoining ones. The end-bars A' are of increased thickness, usually double the size of the others, so the tile may be stronger and the inclosed material may not press out.     B designates screw-threaded rods which fit within openings or holes b in the ends of the bars A A' and are provided with a nut b' at each end. These rods serve to screw the bars and lenses together after the tile has been glazed. By preference, the rods B are threaded their full length, as shown on the right of Fig. 1, although plain rods may be used. Being fully threaded they may be sawed off at any point and will tend to make the tile-work more solid by forming a thread within the concrete or cement that covers them and which hardening when set holds the bars firmly in place.     The bars and rods above described constitute the frame of the tile, which, it will be
