BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 375,838, dated January' 3, 1888.

Application filed April 16,18%?. Serial No. 235,085. (No model.)

To LZZ whom, t may concern..-

Be it known that I, EDMUND STATE, a citizen of the United States, residing at Harrisonville, in the county of Cass and State of Missouri, have invented a new and useful Improvement in Furnaces for Brick-Kilns, of

Vwhich the following is a specification.

My invention relates to an improvement in furnaces for brick-kilns; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure lis a perspective View of a brick-kiln and furnace embodying my improvements. tudinal view ofthe same. Fig. 3is avert-ical transverse sectional view of the saine-,taken on the line m :v of Fig. 2.

A represents a furnace, which is built of brick, and is provided with a longitudinal vertical central compartment, B, having an arched roof, C. At a suitable distance from the ground transverse bars D are placed across the ends of the compartment B, and on these bars are supported the ends of longitudinal grate-bars E, the latter being trussed on their lower sides, as shown in Fig. v2, and provided with vertical longitudinal openings F,as shown in Fig. 3. The front end of the compartment Bis opened and the rear end thereof is closed. The space below the gratebars forms the ashpit G, and the space above the grate-bars and below the arch C forms the combustion-chamber H.

In the side walls ofthe combustion-chamber, and on opposite sides of the latter, are formed fuel-chambers I, which are open on their inner sides and communicate with the combustionchamber, the upper sides of the said fuelchambers being arched, as shown in Fig. 2. From the said fuel-chambers I extend vertical longitudinal openings K, which communicate with the outer sides of the fuel-chambers and pass through the roof of the furnace. The roof L is provided on its sides and front with outwardly-inclined or fiared flanges M, and thereby the roof of the furnace forms a receptacle on which coals may be piled. N rep Fig. 2 is a vertical longiresents longitudinal slides, which cover the upper ends of the openings K and fit on the top of the roof. The front ends of these slides extend slightly beyond the front side of the furnace, and the said slides are guided in hori` zontal openings, with which the front iange, M, is provided.

O represents horizontal longitudinal inlet air-dues, which are formed in the side walls of the furnace on the outer sides of the fuelchambers I, and transeverse slits or openings P are made in the said outer sides of the fuelchambers,and communicate with the air-fines O, whereby the fuel-chambers may be supplied with a constant accession of fresh air.

The operation of myinvention is as follows: The coal is heaped on the roof, as before described,and the fire is started inthe combustion-- chamber. By opening the slidesNthe upper ends oftheopeningsKareuncovered,andapor tion of the coal on the roof of the furnace falls downwardly through-the openings K into the fuel-chambers, and from thence inwardly onto the grate in the combustion-chamber. By this means the fuel-chambers may be always kept filled with coal, and the fire will be constantly supplied with fuel.

Openings R are madethrough the frontwalls of the fuel-chambers, and are adapted for the insertion of pokers to agitate the fuel in the fuel-chambers and prevent it from becoming clogged therein.

From the foregoing description it will be' claiml. The brick-kiln furnace having the longitudinal combustion-chamber I-I open at one end, the ash-pit G under the same, the charnbers I, for the storage of fuel, arranged alongside the combustion-chamber and having their upper sides arched and opening into the combustion chamber nearly the entire length thereof, the air-lines O, arranged on the outer sides of the combustion chamber, and the openings P, communicating with the air-iiues and with the fuel-chambers, substantially as described.

2. The brick-kiln furnace having the longitudinal combustion-chamber H, the fuel-cha1n bers y I, arranged alongside the combustionchalnber and having their upper sides arched and opening into the same throughoutnearly the entire length thereof, the air-fines O, communicating with the fuel-chambers, the verticalV longitudinal openings K, extending from the fuel-chambers to the roof of the furnace,

and the slides N, arranged on the upper ends of the openings K, substantially as described. 3. The furnace ior brick-kilns having the central combustionchamber, the Hue chambers on opposite sides thereof and communieating therewith, the air-fines O and P, eX- 2o tending from the outer air to the outer sides of the fueieharnbers, for the purpose set forth, the vertical openings K, extending from the upper sides ot' the fuelchambers to the roof of the furnace, the latter having the side flanges, M, and the slides N, adapted to cover the upper ends of the openings K, for the'purpose set forth, substantially as described.

In testimony that I claim the foregoing as my ownI have hereunto affixed my signature in 3o presence of two witnesses.
