gain in light-transmitting area, and reduction in the weight of the tile
A is effected.
Where the tile is used for a footwalk or floor, I prefer to fill the spaces between the upper, projecting portions of the lenses with a cement D that is adapted to furnish a firm foothold, in which event the upper surface of the tile is composed entirely of glass and cement.
The omission from around each light opening of the second curb shown in my herein-before named patent materially lessens the cost of the tile by reducing its weight and enabling it to be more easily molded and cast, and renders practicable the employment of a concrete filling for the spaces between the lenses.
Having thus described my invention, what I claim is--
As an improvement in illuminating tiles, a tile
having light openings which are each surrounded by an upwardly projecting
curb, lenses fitted to said openings and having flanges overlapping and
engaging such curbs, and from which project horizontal, supplemental
flanges or ledges and cement to hold said lenses in place whose level
between adjoining lenses is gaged by the supplemental flanges or ledges
thereon, substantially as and for the purpose specified.|
In testimony that I claim the foregoing I have hereunto set my hand this 16th day of September, A.D. 1890.
