shown at the extreme left of Fig. 4 at G, to give additional strength. The ends of the plates rest upon the bearers at the outer side of the area or space, and the inner ends rest upon the projecting flanges II at the bottom of the risers, as shown in Figs. 2 and 3.     In cases where the tiles, either with or without glass, are made in one piece and are to be used at a distance from the place of manufacture, I use a grating of bars extending through or parallel with the corrugations, and having end cross-bars riveted to them, as shown in Figs. 5 and 6, the end bars being made of angle-iron, with the bottom horizontal flange extending beneath the corrugated plate, as shown. By this means the bottom outer edges of the plates are protected from injury and the joints or laps of the corrugated iron are protected by the bent inclosing-strips which fit over the corrugations, as before described, in Fig. 5 this construction is shown in longitudinal section, the filling-in bar resting in grooves of the corrugations, and the angle-iron strips M at each end being riveted to the bars and also to the corrugated sheet, which rests upon the flange of the angle-iron extending beneath the corrugations. Fig. 6 shows a plan view of the same device, and Fig. 7 shows a cross-section of the plate and corrugations looking toward the end, so as to show the flanged piece upon which the corrugated plates are supported, and also showing the strengthening- bars standing within the corrugations. By this construction I produce a support for the artificial stone or concrete filling which forms the surface of the sidewalk, this support having a resisting power much greater than will ever be brought upon it, and by extending the corrugations at right angles with the front of the building they make no obstruction to the light which passes through

the glass, and I am thus enabled to very much increase the amount of light which is available within the basement.     Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is--     1. In a sidewalk, area-covering, floor, or roof, the combination of corrugated metal plates having dovetailed corrugations extending lengthwise of the plate and supporting the sidewalk or surface composed of artificial stone or concrete, and bars, beavers, or strips of metal extending longitudinally within the corrugations, substantially as herein described.     2. In a sidewalk, area-covering, floor, or roof, corrugated metal plates with the corrugations extending lengthwise of the plate, so as to support the sidewalk or surface of cement, artificial stone, or concrete, in combination with strips of metal bent so as to fit the dovetailed corrugations either upon the exterior or interior, or both, substantially as herein described.     3. In a sidewalk, area covering, floor, or roof, corrugated metal plates with the corrugations extending lengthwise of the plate to support a sidewalk or surface composed of cement, artificial stone, or concrete, in combination with a metallic grating comprising the bars D, extending longitudinally within the corrugations, and angle-iron end bars, to which the bars D are riveted, extending across and beneath the ends of the plate, substantially as herein described.     In witness whereof I have hereunto set my hand.
