to the ordinary and common methods of applying plastic materials or in a molded and hardened state, the union of any number of such incased gratings producing roofs and surfaces with fire-proof junction-edges, and consequently complete fire-protection, because of the continuous fire-proof surface of the structure so formed.     In the drawings attached hereto, and making part of this specification, like parts are indicated by like letters in all the figures.     Figure 1 represents an illuminating-cell, A, a a being the top or weather face; b b, the sides; c c, the glasses. The cell is made of metal incased in fireproofing material, (represented by the dotted surface.) d d is a portion of the metal left exposed.     Fig. II represents a cell-quarry holding seven glasses.     Fig. III represents the union of a number of such cell-quarries as employed to form roofs and surfaces.     Fig. IV represents a cast-iron grating, B, made with square light-holes, incased, like the cells, with fireproofing material. The light-holes are represented as set some with square glasses c c and others with circular glasses set in square mounts.     Fig. V represents three of such incased gratings joined by abutting them together, the fire-proof incasement of one grating being in this way brought into contact with the adjoining one, thus forming one continuous surface of fireproofing material over the entire roof or structure, as well upon the under as the upper face thereof. C represents a circular ornamental mount inclosing a circular glass. D represents an octagon mount inclosing a circular glass. E represents a hexagon mount inclosing a circular glass, and F represents a mount made of ordinary brick material in brick form, containing three glasses, and designed for being laid with other bricks, either illuminating or otherwise, in wall, partition, roof, and floor constructions requiring light.     Fig. VI represents an illuminating-grating where the glasses are inclosed in ornamental circular mounts, like C. Fig. VII represents an illuminating-grating where the glasses are inclosed in octagon mounts, like E; and Fig. VIII represents an illuminating-grating where the glasses are inclosed in hexagon mounts, like E. I prefer to make the mounts of colored baked clays, such as tessellated or Minton pavements are made of. They may be combined in the manner of making such pavements, or according to the plan described, and illustrated by Fig. 19, in my American Patent No. 206,332, July 23, 1878, where concrete surfaces are made in ornamental and design form by means either of glasses (when light is an object) made in ornamental shapes, or (where no light is wanted) by means of colored bricks in ornamental shape, the contour of the glasses or bricks expressing the design in the concrete forming the surface between them, the difference between the

Minton pavement and mine being that in place of joining the colored bricks or tiles closely, with only room enough for the cementing material, I place them farther apart, so as to make the concrete cementing body itself form a portion of the design surface.     Figs. IV and V represent incased gratings where a portion of the glasses are shown as set nakedly in square shape, and others of circular shape are set in square mounts to fit the openings of the grating. The gratings here shown are meant to represent the invention as described in my English Patent No. 783, 1874, where the glasses are "set directly" (nakedly) "in the openings as left after the gratings have been incased; or they may be first set in brick mounts, and these mounts be then joined to the incased grating by hydraulic cement."     Fig. IX represents, in cross-section, such a grating where the incasement has been put about the metal in the condition of a plastic material or concrete and allowed to set and harden before joining the glasses to it, the glasses, whether naked, as represented in the figure, or set in brick mounts, as mentioned in the English patent, being then let into the apertures and there fixed by means of hydraulic cement.     Fig. X represents, in cross-section, the same thing as Fig. IX, except that the fireproofing material, instead of being put about the metal in plastic condition, is first molded and hardened, or, if made of baked clay, is then in the form of terra-cotta or brick sections e e, which embrace the bar of the grating d on either side.     Where the gratings are incased by the method represented by Fig. X, it is evident that the glasses, whether naked or in mounts, must be joined to them after the incasement has been put on. It is also evident that where the material is put about the grating in a plastic state and allowed to set and harden, as intended to be represented by Fig. IX, the glasses, whether naked or set in mounts, require to be united by hydraulic cement to the incased grating.     Figs. XI and XII illustrate a mode of incasing the grating, with the glasses, whether naked or in mounts, placed in the openings of the grating before the application of the incasing material, whether in a plastic state or in a molded and hardened one.     Fig. XI represents the plastic method of incasement, the process being interrupted when half finished.     Fig. XII represents the dry method of molded sections. It is seen that the incasement, whether plastic or hard, can be as easily applied with the glasses in position as not, and whether set in mounts or nakedly, the method of setting being the same in both cases.     Having thus fully described and illustrated my invention, what I claim, and desire to secure by Letters Patent, is--     1. Illuminating-gratings or perforated metal plates set with glasses, in combination with a
