2 A.D. 1887.—Nº 5723. Complete Specification Pitt's Manufacture of Building Materials from Glass and in the Application of the same.     At F, Figure 2, I have shown an iron cross which would be excellent for the purpose of giving rigidity in a vertical direction.     Figure 3 shows a section of a brick of another shape, blown at B. The blow holes may be closed under heat or stopped up in any other suitable way.     In Figures 4 and 5, I show other forms of bricks.     In these Figures, C represents the connections, and F, F¹, F², F³ are the iron ties.     The wires F³ F³ of Figure 5 form a double trellis; these wires may be fastened together at their crossing points, with half thickness. A single trellis alone might also be used, placed in the middle of the wall.     In F², Figure 4, I have shown the flat metallic pieces.     For these jointings, I may also use metallic pieces of any suitable shape, tubes, single or double T irons, strips of sheet metal etc. As regards isolated bricks, placed for instance on balustrades, I simply attach them with iron wire on the supporting metallic pieces.     Figure 6 shows, on a reduced scale, six-sided bricks fastened together by bolts T, which have a place reserved for them in the glass, and which maintain the connection by means of iron bands placed in the jointings.     Figure 7 shows bricks perforated with holes, to admit of the passage of a metal bar, serving as a bolt. The bricks are separated by washers. Figures 8 to 12 show, on a full size scale, the mode of joining together the six-sided bricks represented in Figure 6.     Figure 8 is a view of three bricks joined together. Figure 9 is a section from O to P; Figure 10, a section from G to H; Figure 11 a section from M to N; Figure 12 a section from I to K.     In the jointings C, I place a strip of flat or corrugated metal R, perforated with holes. These strips are fastened between the bricks by cramps of bent metal, which form an intertie and serve to hold the bricks when they are placed on the flat part, shown in section in Figure 12. A place would be reserved for these cramps in the glass, as shown at U, figure 8. I can, in certain cases, replace these cramps by metallic wires attached in any suitable manner. Figure 13 shows one of the cramps which I use; the parts V serve to hold the bricks.     In certain cases I cut the necks of the bricks, in order to give them a more graceful appearance.     I employ all the known means for securing the firmness of my panels on the frames and sashes which are to receive them. If the panels rest direct upon iron, I take care to interpose a substance which forms a soft connection, in order to avoid breakage.     My invention can lend itself to any combinations; the pieces of blown glass or bricks may be flat, bent, or in the form of a keystone to make vaults of all kinds; they may be colored at will, and the most varied effects may be obtained.     Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that what I claim is:—     1stly. The manufacture of bricks of blown glass, of any colour, in any shape and of any dimensions.     2ndly. The application of these bricks specially to building purposes and decoration.     3rdly. The ways of joining these bricks together, all substantially as described and shown in the accompanying drawings.         Dated this 19th day of April 1887. CARPMAEL & Co., Agents for the Applicant.
