JOSEPH CICOTTE, OF LOUISVILLE, KENTUCKY, ASSIGNOR OF ONE-HALF TO ANTOINE DUMESNIL, OF LOUISVILLE, KENTUCKY.

BRICK-KILN.

SPECIFICATION forming part of Letters Patent N 0. 694,316, dated February 25, 1902.

Application iled October 18, 1901. Serial No. 79,128. (No model.)

T0 all whom, it' may concern:

Be it known that I, JOSEPH Croorrn, a citizen of the United States, residing at Louis-l ville, in the county of Jefferson, State of Kentucky, have invented certain new and useful Improvements in Brick-Kilns; and I do declare the following to be a full, clear, and eX- aet description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Illy invention relates to brick-kilns, and has for its objects to construct the kiln so as to secure a uniform and expeditious distribution of heat throughout the kiln and to insure the integrity and durability of the permanent portion of the kiln by preventing its displacement from expansion under heat.

In carrying my invention into effect I have been able to burn akiln of brick in less time than was required under former systems,have saved practically all of the brick placed in the kiln to be burned, (a thing that was impossible under the old method,) and have left the base, retaining-Walls, and furnaces, constituting the permanent structure, in perfect condition.

Theinvention consists in the parts and combinations thereof hereinafter set forth and claimed.

In order to make the invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical eect, without limiting my improvements in their useful applications to the particular construction which, for the sake .of illustration, I have delineated.

In said drawings, Figure l is a vertical sectional view of the permanent portion of a brick-kiln embodying my invention. Fig. 2 is a horizontal section of a portion'of the same on line II, Fig. l. Fig. 3 is a vertical section on line III, Fig. l.

Referring to the drawings, B is the base of the kiln, made of tire-brick or any other suitable material, and upon which the brick to be burned are stacked in the usual or any preferred manner between retaining side walls A.

F indicates the furnaces, of which a suitable number are arranged along each of the side walls A in the usual manner for supplying heat to the kiln and burning the bricks.

The base B, side walls A, and furnaces F all belong to the permanent structure of the kiln and rest upon and are connected by a solid subbase X, which is the ground or any suitable substructure.

D is the door of the furnace, through which fuel is introduced.

P is the ash-pit.

The upper part of the furnace is provided with openings at f, through which the air necessary for combustion can pass.

The products of combustion and heat from the furnaces F pass inward into and more or less evenly throughout the mass of bricks stacked on the base B. One important feature of my invention relates to the control Ward the middle of the kiln for a distance equal to about half the length of the iiue a.

c is a third and short flue extending from the furnace at o2 inward through the Wall A to the outer portion of the stacked bricks.

The iiues a and c are a portion of the permanent structure of the kiln, and the fiue b is ordinarily constructed of the bricks to be burned in the process of stacking them. The iiue b may, however, be a permanent structure, if desired.

At their outer ends the flues a b c are or may be controlled by doors i, of iron or tirebrick or any other suitable material, so that the heat may be directed as required for different portions of the kiln by more or less opening or closing said doors. Such doors may be formed by bricks piled in the openings 0 o o2.

The great heat com municated to the base B in the process of burning a kiln of brick causes great expansion of the base and under ordinary construction of the kiln a destruc- IOO tive displacement of the Walls and furnaces. This I obviate by another important feature of my invention, which consists in isolating the base B from the walls and furnaces by forming around the base a space d. I find a Space of about four inches to be sufficient for the purpose of maintaining the integrity of the permanent structure under all conditions of expansion of the base.

The yfiues a, are shown as constructed within the body of the base B and below the Hoorline a; of said base.

The walls of the fiues a, b, and c need not necessarily be continued across the space d, as the natural draftof the kiln will carry all or sufficient of the products ofl combustion from the furnaces across said space. If the flue-Walls are built across the space CZ, it will be with loose bricks, the expansion of which will be taken up by the cracks between the bricks, so as not to be destructive.

1. In a brick-kiln the combination with the baseB and the furnaces, of a series of separate fines from each furnace extending inward above said base different distances toward the middle of the kiln, substantially as set forth.

2. In a brick-kiln, the combination with the baseB and the furnaces, of a series of separate iiues above said base extending from each furnace inward for different distances, and

means for controlling the passage of heat through said lines, substantially as set forth.

3. In a brick-kiln, the combination with the furnaces, of a base B having fiues a leading from ,each furnace and constructed Within said base, and shorter flues leading inward from the furnaces above said base, substantially as set forth.

4. In a brick-kiln, the combination with the furnaces, of a base isolated from said furnaces at its sides, all resting on a solid connecting subbase, substantially asset forth.

5. In a brickkiln,the combination ,with the furnaces, and side walls, of the intermediate base B having between it and said walls the space 0l, said space separating the furnaces from said intermediate base, substantially as set forth.

6. In a brick-kiln, the combination with the furnaces, of the intermediate base B having the surrounding space cl all resting on a solid connectingsubbase and flues extending from said furnaces across said space, substantially as set forth.

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

JOSEPH CICOTTE.
