26,309. West, T., and Lewis, W. I. G. Nov. 13. Brick, pottery, and like kilns.-In kilns or ovens for firing bricks, tiles, pipes, china, and such like ceramic ware, the flues are so arranged that a portion of the fire-hole gases may be admitted to the interior of the kiln at a high position and may be regulated, while another portion is introduced through the floor. According to the arrangement shown in Figs. 1 and 2, one portion of the gases passes from the fire-holes A over partitions b1 into radial flues 2 and an annular flue 1 communicating with a combustion chamber beneath the kiln floor. The top gases pass through damper controlled openings in a partition into extensions of the pockets B, which are covered by perforated plates f, and may be provided with perforations b2. The gases escape from the kiln through a vertical flue N, and may pass to another kiln for drying green goods. The gases may pass from the flue N through apertures n1 into a chimney O. In the modification shown in Figs. 3 and 4, part of the gases from the fire-holes A pass through dampercontrolled openings in a partition h into an annular chamber between inner and outer walls g1, G and through a perforated partition h1 into the upper part of the kiln. The remainder of the gases pass over vertical partitions into flues l1 leading to radial flues l2, which communicate with an annular flue L in the floor of the combustion chamber M. The annular flue may be provided with fixed or detachable perforated covers m1, through which the gases issue into the combustion chamber.
