BRICK-KILN.

Specification of Letters Patent.

Patented, Nov. 14, 1905.

Application filed June 30. 1904:. Serial No. 214,801.

To all whom, it may concern:

Be it known that I, EDWIN DAVIS YOUNG, a citizen of the United States, residing at Oklahoma, in the county of Oklahoma and Territory of Oklahoma, have invented a new and useful Brick-Kiln, of which the following is a specification.

This invention relates to brick-kilns.

The object of the invention is in apositive, practical, and inexpensive manner to insure application of heat to bricks in a kiln in such manner as to secure thorough burning, obviate danger of bulging or crazing, and generally to improve and simplify the arrangement of brick-kilns.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists, generally stated, in a brick-kiln having its arch walls so constructed as, while permitting passage of heat to the benches, to retard its progress, thus to insure even heating of the superposed green brick and the exclusion of air thereto.

Theinvention consists, further, in the various novel details of construction of a brickkiln as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a view in elevation of two of the arches of the kiln. Fig. 2 is a vertical sectional view taken on the line 2 2 of Fig. 1. Fig. 3 is a vertical sectional view taken on the line 3 3 of Fig. 1. Fig. 4 is a horizontal sectional view taken on the line 4 4, Fig. 1, and looking in the direction of the arrow thereon.

Referring to the drawings, 1 and Qdesignate two arches, it being understood that no matter how many arches there may be employed in the construction of the kiln each will be a counterpart of the other, so that a description of one will serve for all. It is to be noted at this point that as the walls in closing the kiln may be of any preferred construction and as they form no part of the present invention illustration thereof is deemed unnecessary. The same may also be said with relation to furnaces.

The springs of each arch are built of bricks 8, the ends of which oppose each other, and the filling between the arch-springs is composed of bricks't, arranged with their sides toward the springs or at right angles to the bricks 3. The lower or base row of bricks i on each side of the arch are separated by spaces 5, through which the heated air from the furnace (not shown) passes, also through lateral flues 6 in the opposed faces of the archsprings', as shown in Fig. 4, thence into vertical fines 7, which intersect the fines 6, as shown in Fig. 4E, and thence upward to the bench. The flues 6 are in this instance shown as extending through but two tiers of bricks; but it will be obvious that they may extend through a greater number of tiers, if found necessary or desirable, and still be within the scope of the invention. The fiues 6 extend in broken order throughout the entire height of the arches, while the fines 7 extend continuously from the base to the bench. In order to deflect the currents of heated air and cause them to traverse a tortuous route, thus to insure even heating of the whole kiln, each two tiers of bricks 9 containing the fines 7 are spaced apart by a solid tier of bricks 10, this order being maintained throughoutthe entire height of the kiln, the upper tiers of fineforming bricks 9 having their flues partly closed by the benches 8.

The arrangement ofthe fiues 7 between the arches, as shown in section in Fig. 3, is straight from the base to the bench, as shown in Fig. 3, and in order to deflect the heated air passing through these flues the bricks 12 forming the benches are arranged in pairs, the solid portion being disposed over the fines 7 and the pairs being spaced to form flues 13, arranged intermediate of the ends of the bricks 10. By the arrangement of the fiues shown the heated air is caused to permeate and traverse every portion of the kiln and to escape to the green bricks, (not shown,) which are disposed upon the benches in an even sheet, thereby causing perfect drying and burning of the green bricks and the prevention of any warping, breaking, or crazing of the bricks. Furthermore, by retarding the escape of the heat, fuel is conserved thereby not only cheapening the procedure, but in a measurable degree reducing the labor necessary to fire the kiln..

While the rows of bricks 4 are shown as disposed at right angles to the rows of bricks 3, it is to be understood that, if preferred, they may be disposed in the same direction as the bricks 3, or the latter bricks may be disposed in the same direction as the bricks 4:.

While the improvements of this invention are of simple character, they will be found IO and having supports spaced apart to present heat-inlets, the filling between the arches being provided With continuous straight vertical fines, and benches having flues breaking joint With those of the arch-springs and filling.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

EDWIN DAVIS YOUNG.
