JAMES C. ANDERSON, OF HIGHLAND PARK, ILLINOIS'.

BRICK-klm.

SPECIFICATION forming part of Letters Patent No. 424,248, dated March 95, 1890.

Application filed November 7, 1889. Serial No. 329,580. (No model.)

` T all whom, t may concern.-

Be it known that I, JAMES C. ANDERSON, a citizen of the United States, residing at llighland Park, in the county of Lake and State of Illinois, have invented new and useful Improvements in Brick-Kilns; and I do hereby declare the following to be'a full, clear, and exact description of said invention, reference beinghad to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in kilns and devices for burning brick, tiles, and

other clay bodies with oil as fuel.

The obj ect of my invention is to burn bricks, tiles, and other clay bodies with oil by completely surrounding the same with the heat, and at the same time protect the bodies to be burned from the direct contact with the flame.

The devices which I have found well adapted for carrying' out my invention are illustrated in the accompanying drawings, in which- Figure l is a vertical transverse sectional view taken on the line X. X of Fig. 2. Fig. 2 is a horizontal sectional view taken on the line y y of Fig. l. Fig. 3 is a longitudinal sectional view.

and are supported by the partitionewall D and the outer walls B and C.

G are hollow tiles made of iireclay or other fire-resisting material, having their ends open and placed at stated intervals crosswise of the car on top of the ire-bricks II, which form a layer to prevent the bottoms of the cars from being injured by the heat.

I are a series of openings or iiues in the outer walls of the tunnels, in which are lo cated the nozzles or burners K, for supplying and distributing the oil, an equal number of ues L being formed inthe partition-Wall D directly opposite and on aline with theflues I, The arch of the tunnel opposite the burner is double-walled, so as to form a j acketed space M, through which the products of combustion pass to heat up the inner Wall of the arch and burn the brick on top of the car in this tunnel.

The openings or flues I and L are placed the same distance apart as the hollow tiles G on the cars, so that when the cars are placed in their proper position the tiles of the car will register with the aforementioned openings or flues, and thus form combustionchambers underneath the pile of brick which has been stacked on the cars over the hollow tiles.

It will be noticed that each tunnel farthest from and opposite the burners is doublewalled, so as to form the jacketed space M, above referred to, and that after the products of combustion giveoff the ercest and most destructive portion `to the tiles G, the heat is transmitted through said tiles to the bottom of the pile of bricks on the cars first, and that the trail of the flame or the milder portions of the heat are carried over the other tunnel through the iiue or space M to burn the brick by transmission through the fire-clay arch O, which spans this tunnel, and it will be seen that after the cars have passed both points where the oil is burned the bricks on both cars, or on the cars in both tunnels, will have been subjected to the same degree of heat, and that a uniform burning Will have been effected without having the bricks come in direct contact with the fiame.

rlhe products of combustion, after having passed through the tiles G and through the jacketed space M, pass to the flues P over the burners to heat up that portion over the burners and aid in the combustion of the water-smoke, and then pass along said flues to the stacks R, heating up the outside walls of the respective tunnels and heating and water-smoking the brick adjacent to the outside walls at the en trance end of each tunnel.

The partitionavall D is provided with numerous openings S, through which the heat IOO escaping from the burned bricks on the outgoing cars is transmitted to the green brick on the incoming cars to Water-smoke and heat the same, as is fully described and `claimed in the patent above referred to.

The devices just described are well adapted for burning clay for ballast for railroad-beds and for the construction of other roads and for burning limestone and cement. It has heretofore been found difficult to burn clay for ballast &c., for the reason that when piled in any considerable body the heat cannot penetrate the mass unless spaces or int-erstices are formed therein7 the clay itself being a poor conductor of heat, and in burning clay for the purpose named in accordance with my invention the cars, with the lire-proof floor and the tiles G in position, are run to the clay-bank and the clay loaded thereon as mined without the necessity of drying the same. The cars are then run into the tunnels, as already described. The water-smoke is eliminated in the initial stages of burning and carried forward through the liues C and mingled with the products of combustion in the iue or jacketed spaces M of the kiln, where it comes in contact with the flame from the tiles G and is consumed.

What I claim, and desire to secure by Letters Patent, is-

l. In devices for burning brick on cars, the tiles G, located thereon as described and adapted to register with openings in the outer Wall of the kiln in which the furnaces or burners are located, and with openings L in the partition-Wall, which communicate with the jacketed spaces M, whereby the hottest part of the flame is utilized to burn the bottom of the pile and then the top of the uppery portion of the brick on the cars in the adjacent tunnel, as set forth.

2. In a double-tunneled kiln of the character described, the` two trains of cars adapted to pass through the tunnels in opposite directions, said cars being provided with openended tiles, on which the articles or material to be burned is piled, in combination with the iues I, burners K, Iiues L, and jacketed space M, as set forth.

In testimony whereof I afliX my signature in the presence of two subscribing witnesses.
