these beams and extending in a transverse direction are the beams or angle-irons m, n, and o. (Represented on plan view 3 and sectional views 4, 5, and 6.) These are shown attached to the front of a building, or may be attached to any other part. Fig. 7 shows the inner end of beam h' resting on a beam-riser and the outer end resting on a T-beam, which may form the curb to the gutter. These various figures represent the frame-work to support the corrugated metal plates, as described, either with or without glass lenses and concrete, artificial-stone, or like filling, with its top forming the top surface.     Figures 8 and 9 represent sections of a curved-roof light or skylight, part with and part without glass, sustained on arched beams or bearers on the sides. The bottom glass and filling is the same as described for the others. By reason of the corrugations extending transversely they are easily bent on any circle or angle while retaining their full strength to resist strain. In this case the groove may be of any form, requiring no patterns for different curves or angles and no expense to make them conform to the shape of the roof. In other constructions of this kind or for this purpose expensive patterns have to be made for every different curve required, it being usual to make patterns of a mixture of block-tin and lead and bend them to the curve or angle and then chase and finish up the soft metal and then cast from that the iron patterns and finish them.     The expense of patterns in a small skylight is so much that in some cases the expense prohibits its use.     Figure 1 of my patent of August 7, 1883,

No. 282,641, shows an iron skylight of the kind where the illuminating-tile is all of iron and glass, of which special patterns have to be made for every different curve. The present construction is also of less expense for flat skylights than others.     Having described my invention,what I claim as new, and desire to secure by Letters Patent, is--     1. In an area covering, floor, or sidewalk, metallic supporting-beams and transverse corrugated metal plates with grooves or channels made widest at the bottom, the elevated horizontal or curved parts between the grooves perforated and fitted with glass, in combination with a filling between the glass of artificial stone or concrete, which is supported in the plates and fixed to the floor or surface, substantially as herein described.     2. In a roof, curved metallic supporting beams or bearers with transverse corrugated metal plates, in combination with a filling of artificial stone or concrete, which forms the top surface, substantially as herein described.     3. In a roof, curved metallic supporting-beams with transverse corrugated metal plates, the elevated horizontal or curved parts between the grooves perforated and fitted with glass, in combination with a filling between the glass of artificial stone or concrete, which is supported by the plates and fixed to the floor or surface, substantially as herein described.
