SPECIFICATION forming part of Letters Patent No. 619,575, dated February 14, 1899.
Application filed June 11, 1898. Serial No. 683,208. (No model.)
To all whom it may concern:
    Be it known that I, JACOB JACOBS, of New York city, in the county of New York, and in the State of New York, have invented certain new and useful Improvements in Lights for Sidewalks, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which—
    Figure 1 is a perspective view of a pavement-light embodying my invention. Fig. 2 is a vertical longitudinal section showing two forms of tiles. Fig. 3 is a perspective view of the frame alone, and Fig. 4 is a like view of a tile for use with a frame of different construction.
    Letters of like name and kind refer to like parts in each of the figures.
    The object of my invention is to provide a light for sidewalks and other places which will be water-tight and to this end said invention consists in the light having the features of construction substantially as hereinafter specified.
    In the carrying of my invention into practice for the construction of a sidewalk-light I employ a frame A, rectangular in outline, that is constructed to hold several illuminating-tiles B and B, two of the latter being used in the embodiment of the invention herein illustrated. Each of the tiles B, provided with lenses or glasses C and D, rests upon inwardly-projecting flanges D and D on the frame that lie in such a plane below the top surface of the frame that the upper sides of the tiles will be flush or substantially flush with such top surface. In the under side of each tile B, close to and parallel with each side thereof, is a groove or channel b, that fits over a rib or curb d, which rises from the flanges D and D around the frame-opening, over which the tile is placed, said rib or curb d being away from the edge of the flange, so that there is a bearing for the tile on the flange on both sides of the rib or curb. Between the under side of the tiles and the flanges D and D, between the sides of the tiles and the sides of the frame A and also between the abutting sides of the tiles, a suitable cement is placed.
    It is apparent that the presence of the rib or curb d and the groove or channel b most
effectually bars the passage of water, even should it find its way between the frame and tiles, and thus the structure is rendered water-tight. The ribs also serve to strengthen the frame.
    The curb or rib d for one tile may be distinct from that of the other; but, if desired, the ribs at the sides that aline may, as shown by dotted lines in Fig. 3, be connected together or be continuous, in which event a tile having the construction shown in Fig. 4 will be used which has notches b' and b', that respectively fit over the two extra intervening portions of ribs.
    The tiles B and B may be simply metal plates perforated for the reception of the lenses or glasses, having lugs or protuberances on the upper side to give a foothold, or they may be plates having cavities in their upper sides for the reception of a filling of cement around and between the upper parts of the lenses. Both forms of tiles are shown in the drawings. The tiles are fastened to the frame by bolts or screws.
    Having thus described my invention, what I claim is—
    1. The combination of the frame, provided with inwardly-projecting flanges from which rise ribs or curbs located away from the inner edges of the flanges, and a tile or tiles fitting the frame, and having bearings on said flanges on both sides of the curbs, and having grooves in their under sides that receive the curbs, substantially as and for the purpose described.
    2. The combination of the frame provided with inwardly-projecting flanges from which rise ribs or curbs, located away from the inner edges of the flanges, and a tile or tiles fitting the frame and supported on said flanges on both sides of the curbs, and having grooves in their under sides that receive the curbs, and cement between the adjacent portions of the frame and tiles, substantially as and for the purpose described.
    In testimony that I claim the foregoing I have hereunto set my hand this 10th day of June, A. D. 1898.
JACOB JACOBS.
