d indicates concrete.     e indicates the neck or shank portion of the glass.     f indicates the base of the glass and the interlocking cams thereof.     g indicates the bayonet-slots of the light-holes, i i interglass spaces.     m' n' o' in Figs. 2 and 3 indicate junction-lines between fractional gratings 1 2 3 4, composing the combination-tile.     I will now describe my improved mode of concrete-light manufacture. When the grating is a one-casting tile, as represented by Fig. 1, the light-holes will at the start be all open, as represented at A, Figs. 1, 2, 3, when glasses of the kind illustrated by Figs. 4, 5, 7 will be applied to the same, as shown at B, Figs. 1, 2, 3, 5, the cams f f of the glasses, Figs. 4, 5, and 7, entering and passing through the bayonet-slots g g, Fig. 6, and interlocking with the plate a a, Figs. 3, 5, 6, when the whole surface of the grating will appear as shown at B, Fig. 3, all the glasses being firmly set in position with the interglass spaces i i all open and ready to be filled with the plastic cement. The plastic material is now added, and being smoothly troweled and floated over the face of the work all the interglass spaces are filled with cement, as shown at C, Figs. 1, 2, 3, and made true, level, and flush with the tops of the glasses, as shown at C, Fig. 3, when the work is finished. As soon as the cement becomes set and perfectly hard the glasses are then virtually embedded in stone and remain immovable, so that the glasses not only hold the stone to the grating, but the stone holds the glasses, a sort of "mutual-benefit" arrangement between the "members" composing the partnership.     In describing the mode of manufacture with reference to the one-casting tile I equally describe it with reference to the combination-tile.     Fig. 2 represents a mode of construction where the fractional gratings that compose the combination-tile are supposed to be first placed within the panel-spaces of the structural framework before the glasses and plastic facing are added to the gratings; but, if desired, each one of the fractions 1 2 3 4 may be treated as a one-casting tile and concreted by itself, the interlocking glasses being applied as described, the fractions being afterward joined together in the panel-spaces of the foundation-frame.     One of the advantages connected with the employment of interlocking glasses for combination-tile construction and manufacture is shown in Figs. 2 and 3, where the half-light holes of the fractions at the junction-lines m n o on being closed by the glasses become by the simple act of entering and slightly turning the glasses as complete and virtually whole-light holes as any other in the gratings,

the mechanical action of the glasses uniting the fractions into a homogeneous plate equivalent for all practical purposes to a one-casting tile.     The advantage and effect of the milled or roughened sides of the head of the glass with reference to the concrete is shown in Fig. 5, where d, the concrete, is seen to bond with the rough side of the glass.     Having thus fully described and illustrated my invention, what I claim as novel therein, and desire to secure by Letters Patent, is--     1, In illuminating tiling or gratings, the combination, with a metal grating or perforated plate, and concrete overlying the same, of glasses embedded in the concrete and over the openings of the plate, formed with a foot or base having cams thereon to interlock through the openings with the plate, substantially as herein set forth.     2. In illuminating tiling or gratings, the combination, with the underlying grating and overlying concrete, of glasses formed with cams at the base to interlock through the openings with the plate, and with milled or roughened sides to bond with the concrete, substantially as herein set forth.     3. In illuminating tiling or gratings, the combination, with a metal grating or perforated plate, and concrete overlying the same, of flat top glasses embedded in the concrete, and over the openings of the plate, formed with a foot or base having cams thereon to interlock through the openings with the plate, substantially as herein set forth.     4. In illuminating tiling or gratings, the combination, with the underlying grating and overlying concrete, of flat top glasses formed with cams at the base to interlock through the openings with the plate, and with milled or roughened sides to bond with the concrete, substantially as herein set forth.     5. A perforated plate or grating made with bayonet-slotted light-holes, in combination with glasses formed with a foot or base to pass through the same and interlock with the under side of the grating when the grating is combined with a plastic face or overlayer of cement or concrete that on hardening permanently fixes the glasses in place, the sides, of the heads of the glasses above the face of the grating at the same time forming interglass spaces or retaining-cells for keying the plastic overlayer to the face of the grating.     6. A perforated plate or grating made with bayonet-slotted light-holes, in combination with glasses formed with a foot or base to pass through the same and interlock with the under side of the grating when the grating is combined with a plastic face or overlayer of cement or concrete that on hardening permanently fixes the glasses in place, the sides of the heads of the glasses above the face of the grating at the same time forming interglass spaces or retaining-cells for keying the plastic overlayer to the face of the grating, in combination with
