BRICK-KILN.

SPECIFICATION forming part of l 'ietterslPatent No. 660,880, dated October 30, 1900.

Application filed April'20, 1900- To all whom it may concern:

Be it known that I, EDGAR ABER, a citizen of the United States, and a resident of Jacksonville, in the county of Cherokee and State of Texas, have invented new and useful Improvements in Brick-Kilns, of which the following is a full, clear, and exact description. My invention relates to brick-kilns, and has for its o bjects'to provide means for burning bricksin a much shorter time and more effectively than is possible with usual construcs tions, and, further, to protect the kiln-walls against the injurious effects of heat.

To these ends my invention consists of'cer tain features of construction'and'arrangement of parts, as will be fully described hereinafter and particularly pointed out in't-he claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in the direction of the arrow in Fig. 2.

in which similar characters of i'eferenceindicate corresponding parts in all the figures.

Figure 1 is a front elevation of a kiln embodying my invention, the view being taken Fig. 2 is a plan thereof. Fig. 3 is a sectional plan on line 3 3 of Fig. 1. Figs. 4 and 5 are cross sectional elevations on lines 4 4 and 5 5, respectively, of Fig. 1; and Fig. 6 is a longitudinal sectional elevation on line 6 Got Fig. 3.

The improved kiln comprises a suitable casing consisting of a front wall A. a rear wall B, and side walls C, which may all be constructed of common bricks, no fire-brick being required in my kiln. The walls preferably have upright ribs'or pilasters D, upon which are applied posts E, fastened to the walls by bolts F and extending upward beyond the top of the furnace. The projecting upper ends of the posts E are connected by truss-rods G, passing through them loosely and having coiled springs H interposed be tween the posts and the outer ends of the truss-rods. This construction allows for an expansion and contraction of the kiln walls. To the lower ends of the posts on the front wall A are secured by bolts F plates I, which extend downwardly over said wall in line with the partitions A, which form the firechambers J and ash-pits J' of the kiln.

X X indicate the ground-line of the kiln.

K designates the grates, which may be of any suitable construction.

arches L.

Serial No. 13,607. (No model.)

The gases from the fire-chambers J pass into the central space of the kiln (between the four walls thereof) through throats or Into this central space I place the green or unburned brickin the following manner: First I line the walls A B C of the kiln with vertical layers of brick M, so that the heat can not reach the kiln-walls directly,

thus protecting the latter. Then I place upon the floor or ground a course of bricks N, running from front to rear and spaced from each other transversely, as shown at N. At intervals I leave spaces 0 to form eyes or cha nnels running from the front wall A toward the rear wall B and communicating at their rear ends with a chamberor channel P, ex-" tending upwardly the whole length of the rear Wall E, or, rather, of the lining M ofsaid:

wall. 'Ihe'upper end ofthis channel maybe closed bya suitable cap Q, Fig. Upon the course of bricks N, I lay another course R, the

bricks of this course abutting against each i other from one side of the kiln'to the other,

but being spaced from each other'frorn front to rear,- as shown at R. It will thusbe seen I that the bricks of the course N are spaced tov form channels N, extending at a right angle to the channels R, formed between the bricks R.' The latter of course are omitted where the eyes 0 pass from front to rear, as shown -"in Fig. 3. vAbove said eyes I place green bricks in alternate layers N and R,.and on top of these I place a layer of bricks without interstices, preferablyin two superposed courses S, with broken joints, which layer extends from the liningof the front wall A to a point within a distance from the rear channel P. At the rear end of the solid or imperforate layer S, I place an uptakeT, and in the rear of said uptake the brickwork consists of alternate coursesN and R with in: terstices, as above described. At the front end of the solid or impert'orate layer S is lo cated another uptake T and between the two uptakes the brickwork consists of open courses R, of the character described, alternating with solid courses S Ontop, between the rear channel P and the front uptake T, I place another solid. layer of brick S In operation, the green brick having been stacked within the kiln, as described, thecap or plate Q is first removed, and the heat passing from the fire chambers J through the throats L will reach the eyes and frbnl thence travel to the upward channel P at the rear, and will also pass through the interstices N and R in the courses of bricks N and R, passing out finally through the upper ends of the rear channel P and of the front uptake T. The heat will first drive out the moisture or water-smoke the bricks, as it is termed in the art. When this has been accomplished and the burning of the bricks is to be completed, the cap Q will be put on top of the structure to close the upper end of the rear channel P, and all the heat will then be compelled to travel as indicated in Fig. L-that is, it will pass through the interstices N and R of the upper courses (above the level of the solid layer S) to the rear uptake T, and from the latter through the interstices R. to the front uptake T, whence it will escape to the chimney.

' It will be observed that with the above-described construction the kiln proper is extremely simple and requires no flues or channels beyond the throats or arches L. All the other channels for distributing the heat are formed by the green bricks themselves. The heat is uniformly distributed throughout the entire body to be burned, and as a result the operation is conducted expeditiously and effectively. The linings M protect the kilnwalls against the injurious effect of excessive heat. The cap Q, as described, permits of changing the path of the heatedgases, so that they will first thoroughly dry the green bricks and then burn them. The entire construction is strong, simple, inexpensive, and very efficient.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. Akiln having inclosing walls, a filling or charge of green bricks located between said walls and consisting of superposed layers or courses having circulating-channels, the channels of adjacent layers extending at an angle to eachother, eyes extending in the lower portion of the filling from front to rear, a channel ext-ending upwardly at the rear wall of the filling and communicating with said 'eyes, a solid or imperforate layer of bricks located in the upper part of the kiln and extending from the front wall thereof to Within a distance from the rear wall, and up takes rising from the front and rear ends of said solid layer.

2. A kiln having iuclosing walls, a filling or charge of green bricks located .between said walls and consisting of superposed layers or courses having circulating-channels, the channels of adjacent layers extending at an angle to each other, eyes extending in the lower portion of the filling from front to rear, a channel extending upwardly at the rear wall of the filling and communicating with said eyes, a solid or imperforate layer of bricks located in the upper part of the kiln and extending from the front wall thereof to within adistance from the rear wall, the filling above said solid layer consisting of alternatingppen and imperforate layers, uptakes rising from the front and rear ends of said solid. layer, and an imperforate top layer extending from the front uptake to the upper rear channel.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. H

, EDGAR ABER.
