SCHNEIDER AND CO.’S WORKS. elevator for the lifting and distributing, on the first floor, of the clay prepared in the pug mills ; an automatic bridge with trucks to carry down the goods manufacturée! on the first floor ; three large crushing machines fitted with auto- matic feed and central screening arrangement. Fig. 39 Plate VIII., gives an excellent idea of the crushing mill plant. Each of the crushing machines is fitted with a bucket elevator, which distributes the erushed, mixed, and sifted products into separate bins. The plant also includes a crushing machine with revolving trough ; a complété The circular kilns are used foi- baking the bricks of special form ; the other kilns are used foi’ preliminary roasting of the raw material. The total area occupied by the works is 35,000 square yards. Circular Kiln.—The circular kiln (Figs. 40 to 42) is 65 ft. in diameter. The chimney is in the centre, and is 98 ft. high. The compartments are fourteen in number ; they are 9 i’t. 6 in. deep, 8 ft. 6 in. high, and their average width is 8 ft. 3 in. They communicate with each other by means of three openings in the walls, and at the bottom FwM Sedicrv AB.

Kilns.—There are two circular continuons gas kilns, illustrated by Figs. 40 to 42, each clivided into fourteen compartiments ; there are also two ordinary kilns, one burning coal, the other gas ; one reverberatory kiln and a series of eiglit Perret kilns in three stories, which burn coke clust. These last serve, with numerous other kilns, to heat the drying rooms and closed shops, thus enabling tlie work to be carried on in the winter. the gases arrive below the floor through three vertical openings. Combustion begins near the separating walls, and spreads through the flues, which are arranged by placing the bricks in the compartments. The baked bricks in course of cooling serve to heat the air necessary for the combustion of the gases. The air passes through five or six compartments, each hottet than the other, before arriving in contact with the gases, in the compartment where the kilning is in progress. The products of combustion (gases and smoke) flow through the compartments following the one in which the kilning goes on, and heat them before escaping through
