IMPROVEMENT IN BRICK-KILNS.
Specification forming part of Letters Patent No. 138,905, dated May 13,1873; application filed January7 11, 1873.
To all whom it may concern:
Be it known that I, ALBERT WILLIAM MAX' MAAss, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Perpetual-Burning Brick- Kiln; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which- Figure 1 is a cross-section of myimproved kiln, and Fig. 2 is a sectional plan of the same. Like letters refer to like parts in each gure. The nature of this invention relates to certain improvements in the construction and method of operating perpetual-burning circular brick-kilns, and is more especiallyT designed as an improvement on the kilns forlwhich Letters Patent were issued to Frederick E. Hoffman on June 13,1865; and it consists in a circular arch divided into a number of compartments by radial partitions, and the peculiar arrangement, with relation thereto, of the smoke-channels, which connect said compartments or chambers alternately at opposite ends, and of the doors for opening or closing communication between them; also, in the arrangement of the fuel-doors, air-registers, and stop-valves with relation to a circular smokechamber, radia-l flues, and a central smokestack, as more fully hereinafter set forth.
Inthe drawing, AB C D E F Gr H I K L M N O represent the chambers or compartments formed by partitions radiating from the inner circular Wall of the kiln to the outer one. These chambers are connected with each other through the smoke-channels a b c d e f g It t' k l m n c cut through the radial partitions alternately at the inner and outer ends of said partitions. R is a smokestack rising from the center of the kiln, and is divided in the lower part into four iiues by cross-diaphragms, into which empty four iiues, Q, from a circular smoke-arch, P, which surrounds the base of the stack. AThe smoke-channels a b c, &c., all empty into the bottom of the smoke-arch, and their mouths may be closed at will by valves 0r covers o worked by rods o passing up through the top of said smoke-arch. X and X are iron sliding doors for disconnecting the compartments by closing the alternating openings, being inserted from the top of the kiln and slid down at such openings on the partitions as I may desire to close. Tis an opening through the outer wall into each compartment, provided with a suitable door for giving access to its interior for the purpose of iilling in the green and removing the burned brick. q are connecting-channels between the compartments, which can be opened or closed by gates t to regulate the draft and heat. s are channels for admitting air to the compartments, which channels can be closed by covers s at the top. a are fuel-holes in the arch-top, through which fuel can be introduced to the compartments, and are closed by iron covers. r are draft-channels in the bottom of the kiln. The plan shows a kiln of fourteen compartments, which can be operated in the following manner as two separate kilns: The compartments from A to G, inclusive, represent or constitute one kiln and the compartmentsfrom H to O, inclusive, constituting the other, the two kilns being separated by the sliding doors X and X but by changing the doors in the order indicated by the letters the operation of burning can be carried from one compartment to the next, and so on around the circle. To make it clearer I will suppose that the re is in the compartments D and L, and the com-- partments E F and M 'N are filled with green brick, which can be heated by the waste-gases from D and L to drive off the water-smoke, the gases finding exit through the channels f and a into the smoke-chamber l?, and thence through the iiues into the smoke-stack, the channels o, a, b, c, d, e, and g of the one kiln and g, h, i, la, l, and m of the other kiln being closed. The compartments A and H are being emptied of their burned and cooled bricks while the compartments B C and I K are iilled with burned bricks cooling ofi", through which the air coming from the compartments A and H and going to the fired compartments passes, which cools off the brick, and saving otherwise wasted heat by heating the air going to the burning kilns. The compartments G and C are being iilled with green brick, and when this is done the slide-door X is moved to o and the door X to q. The covers o in the provided with the movable slides X X', as!
and for the purpose set forth.
2. The arrangement, with relation to the stack R, smoke-chamber P, and compartments A, B, C, &c., of the smoke-channels a, b, o, &c., valves r, openings T, channels g, gates t, airchannels s, covers s', fuel-holes u, and draft-channels r, substantially as and for the purpose set forth. i
