the surface of said plate will prevent water from passing over the same.     Having thus fully set forth the nature and merits of my invention, what I claim as new is--     1. An illuminating-tile provided around its light-opening with an annular groove, in combination with a lens which has an annular flange around its edge, that is adapted to fit downward into said groove when said lens is in place, substantially as and for the purpose specified.     2. An illuminating-tile having a light-opening that is surrounded by two concentric curbs, in combination with a lens which is adapted to fit within said opening, and is provided with a flange that extends over the inner curb and into the space between the same and the outer curb, substantially as and for the purpose shown.     3. An illuminating-tile having a light-opening that is surrounded by two concentric curbs, the innermost of which curbs is higher than

the outer curb, in combination with a lens which is adapted to fill said opening, and to project over said inner flange into the space between the same and said outer flange, substantially as and for the purpose set forth.     4. The combination of an illuminating-tile having a light-opening that is surrounded by two concentric curbs that are separated by an annular space or groove, a lens adapted to fill said opening and to extend over the inner curb and into said annular groove, and cement or other material which is adapted for use within the latter in sealing the space between the projecting flange of said lens and said flanges, substantially as and for the purpose shown and described.     In testimony that I claim the foregoing I have hereunto set my hand this 17th day of October, 1882. DAVID G. BEECHING. Witnesses:     JAMES M. LA COSTE,     CHARLES O'CONNOR.
