If deday of July, 1875. v I 1 Now, therefore, being desirous of reissuing between said cross-bars a and a to the bottom said Letters Patent, herewith surrendered, I of the tile, in which event such extended perhave prepared and do hereby declare that the tion would be reduced in horizontal dimenfollowing isa full, clear, and exact description ,sions, as seen in Fig. 5. The vertical portion, of the said invention, reference being had to or web, of each cross-bar forms aseries of in the accomoanyins drawings, making a part of verted ar hes. the abutment-s a" of which exthlsspeciucatio n'in whichi tend upward to and ar Figure 1 is a perspective view of the upper surface of the tile. sideof'myimproved tile. Fig. 2 is alike view The metallic portion of the tile being thus [of the lower side of the same. Fig. 3 is a constructed, the lenses are placed in position, cross-section of said tile, and Figs. 4 and 5 lenses is cylindrical from its upperend downward nearly to its lower end, at which latter e nus with t e upper the same and the cross-bars are filled with -a tached from its frame.

'' Letters of like name and hind refer to like ..p'arts ineach'of the figures. Thedesign of my 'invention' is to improve hesive, material, which composition is applied fore the tile used.

It is intended that the uppersuriaces of the lenses, the side and cross bars, and the filling; composition, shall have the same plane, so that the feet of a person standing upon the tile shall be supported: equally. by each rnaterial I named, in which eventall liability to slipping is avoided and a firm foothold afforded by the? gritty surface of the filling. The principal object sought by the cutting away of portions of the cross-bars between the lens-openings is to-enable the plastic filling within each opening to be combined with and formpart of such filling ,within the other openings, andthcreby form upon the upper surface of the tile a continuous surface of non,- slipping material, while at the same time the abutmcn ts a oifer suflicient resistance to wear to prevent either the glass or the filling-composition from becoming abraded with undue purpose hereinafter set forth. rapidity, said con'iposition furnishing a firm In the annexed drawings, A represents a foothold that could notbe obtained by the use or glass, and the union of said matewalking-surface; and it consists principally bars that have the. forms of inverted arches, and in which the abutments of said arches are flush with the uppcr-= surface of said tiie, sub stantially as and for the purpose hereinafter specified. It consists, further, in an illuminating-tile provided with cross-bars, each of with the upper surface of said tile, while another'fiortiohis removed to permit the plastic .flllin'g to pass from one lens-opening to ansame, substantially as and for the purpose hereinafter shown. It consists, finally, in an illuminating-tile having a portionlof its upper surface composed of emery combined with adare supported, each of'which sired, said lens maybe extended downward and the spaces between the upper portions of composition. formed of emery and suitable adin a plastic state and allowed to harden berials enabling an illuminating-tile to beconstructed that is as easy to the foot and as safe from slipping as is an ordinary wooden floor.

The inverted-arch form of the cross-bars gives to them unusual strength, and enables the tile to be constructed with less weight of metal than would otherwise be necessary, while,.'from the peculiar form of the lens, no liability exists to their displacement, and an increase is effected in their light-transmitting qualities.

As a walking-surface the emery composition possesses important advantages, as it not only furnishes a firm, sure foothold, but is so hard as to have great durability without being liable to become glazed by use.

. Having thus fully set forth the nature and merits of my invention what I claim as new 1s Ir 1. An illuminating-tile, A, provided with cross-bars a. and a, that have theforrn of inverted arches, the abntments a of which arches are flush with the upper surface of said mit the plastic filling to passfroin one lensopening to anothenand form an interlocked mass of the same, substantially as and for the purpose shown.

3. An illuininatiugtile, having a portion of its upper surface composed of emery combined with adhesive material, substantially as and for the purpose set forth.

In testimony whereofll have hereunto set my hand, this 18th day of August, 1875.
