The joint thus produced possesses great strength and durability, and is not liable to leak under any ordinary usage.     Having thus fully set forth the nature and merits of my invention, what I claim as new is--     1. The lens for illuminating-tiles, having its lower portion elongated diametrically and provided with a circumferential groove, substantially as and for the purpose specified.     2. In combination with the lens-supporting portion of an illuminating-tile provided with an elongated lens opening, the lens having its lower portion correspondingly shaped and adapted to be passed through the lens-opening, and having a circumferential groove adapted to allow the lens to be turned after its lower portion has been passed through the opening, all substantially as and for the purpose shown.     3. In combination with a lens-support of an illuminating-tile provided with one or more elongated openings, one or more lenses having their lower portions shaped to correspond with such openings and provided with circumferential grooves adapted to allow the lenses to be turned in the openings to bring their longest diameters at right angles to the longest diameters of the openings, and a body of cement surrounding the lenses, substantially as and for the purpose described.     4. In combination with the lens-supporting

portion of the tile provided with elongated openings, the lenses correspondingly shaped and grooved to receive the edges of the openings, turned to bring their longest diameters at right angles to the longest diameters of the openings, and cement in the grooves in the lenses, substantially as and for the purpose specified.     5. In combination with the lens-support of an illuminating-tile provided with an elongated lens-opening, the lens correspondingly shaped and having the cylindrical neck adapted to allow the lens to be rotated in the opening to bring the longer diameter of the lens across the opening, substantially as and for the purpose described.     6. In combination with a supporting-frame, an illuminating-tile having in its edge a groove and an illuminating-tile having in its edge a rib entering the groove in the other tile, cement placed between the engaging edges of the tiles, and bolts passing through the lower portions of the tiles and portions of the supporting-frame, substantially as and for the purpose described.     In testimony that I claim the foregoing I have hereunto set my hand this 8th day of November, A. D. 1883. JACOB JACOBS. Witnesses:     WILLIAM J. FINIGIN,     ROBERT J. COWAN.
