wall, N, dividing the lower portions of the building, so that the structure now forms two distinct buildings from top to bottom, (the A portion only being here shown,) the purpose of the figure being to represent an ordinary long store, built on a lot eighty to one hundred feet deep, where the stories above the ground floor are set back in order to obtain light for the principal story, this being the style in in which such stores are commonly built.     Fig. 4 repeats Fig. 3 with modifications, for G, formerly a window or translucent screen in the side wall of A for shutting out the weather, is now a skylight or window in the roof; this change destroying the function of M as a roof with respect to the weather, but leaving it unimpaired as a daylight-reflector with reference to illuminating the interior of the building.     Fig. 5 repeats Fig. 4, except that the glass plate M, in place of being a large single sheet, is here divided into two plates, the improvement of an indented back, b', upon the glass being added to produce a luster upon the internal reflecting-face, b, of the plate, giving it the appearance of a corrugated silvered daylight-reflector.     Figs. 6, 7, 8, 9 illustrate illuminating-roof and roof-pavement constructions, made of iron gratings, set with squares of glass formed with a cluster of lenses upon its weather-face, the iron gratings being cast with parallel bars in one direction only, there being no cross-bars of iron. Instead thereof cross-bars of glass are made use of; some of which are cast with a projection below in the form of a bent glass plate, to serve the purpose of a translucent reflector. Fig. 6 shows the construction of the glasses and grating. Fig. 7 illustrates the cross-bar reflector; Fig. 8, application of the invention to basement-extension work; Fig. 9, application of the invention to rear-extension roofs of principal story or ground floors of buildings. O is the iron grating; P, cluster lens-glass square; c c, lenses on face of the square; B, glass cross-bars; S, reflector formed upon cross-bar.     When I make constructions of pressed glass, the translucent reflectors are most conveniently made of plates about eight by twelve inches, the thickness being from a quarter to half an inch. Plates of this size may then be readily cast with a lustered internal reflecting-face, produced by proper crimps or indents made upon the back of the plate in the process of molding, as represented at b, Fig. 5; but I do not confine my invention to making such reflecting glass plates always with the cross-bar portion B attached, for they may be quite

as conveniently made without the cross-bar attachment, and even more so; neither do I limit myself to any size, shape, or kind of translucent glass reflector, nor to any mode of using them that will accomplish the purpose of their functions when combined with light-transmitting roofs, for I have shown several ways of doing the work, and the invention admits of many modifications in construction.     In employing rolled glass I find ordinary rough plate to answer a good purpose when cut into strips or louvers of six inches width and lengths of about thirty inches. These louvers I arrange in frames, either of wood or iron, and place under the skylight or illuminating-roof; as represented in Fig. 5; but I prefer for cheapness to employ these reflectors in sheets or plates of largest practicable size, no shadow being cast by them; the object of using the glass in the form of louvers being merely for the sake of appearance, in order to give a better finish to the rear portion of the room or store requiring the construction.     What I claim as my invention, and desire to secure by Letters Patent, is--     1. A translucent daylight-reflector, made of glass in slat or louver, or in sheet or in plate form, the same being practically flat on both sides, the only reflecting-surfaces being an external face on: the outside face of the glass and the internal reflecting-face of the opposite side of the glass, substantially as and for the purposes herein set forth and illustrated.     2. Translucent daylight-reflectors, made with a crimped, corrugated, or indented back, substantially as and for the purposes herein set forth and illustrated.     3. Daylight-reflector roofs and roof-pavements, made by combining translucent daylight-reflectors with skylights, illuminating-grating roofs or roof-pavements, substantially as and for the purposes herein set forth and illustrated.     4. Daylight-reflector roofs and roof-pavements, made by combining translucent plates, slats, or louvers with skylights, illuminating-grating roofs or roof-pavements, substantially as and for the purposes herein set forth and illustrated.     5. Daylight-reflector roofs and roof-pavements, made by combining translucent reflector cross-bars with glass plates and metal-grating glass-holders, substantially as and for the purposes herein set forth and illustrated.
