JACB H. BEIDLER, OF MOUNT P'ULASKI, ILLINOIS;

BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 278,080, dated May a2, 1883.

Application liled February 1,A 1883. (No model.)

- To all whom it may concern:

Beit known that I, JACOB H. BEIDLEma citizen of the United States, residing at Mount Pulaski, in the county of Logan and State of Illinois, have invented certain new and useful Improvements in `Brick-Kilns,` of which the following is a specification, reference being had therein to the accompanying drawings.4

This invention relatesto certain new and useful improvements in brick-kilns, and has for its objects to provide, rst, for introducing to the tire-arches atmosphericair in regulated quantities, whereby the proper amount of oxygen may be supplied in order to effect a thorough and perfect combustion of the fuel secondly, to provide for maintaining an equal amount ofheat throughouttheentirekiln and, thirdly, in supplying combustible material or fuel to the load 77'or mass of brick being burned. These objects are accomplished by thc means illustrated, the same consisting of forin-` ing the bed or foundation for the kiln of clay or cement, and in building up in the same a number oflongitudinal and transverse air passages or conduits communicating with each other and with the lire-arches, and supplied with suitable devices for regulating the influx,

and the direction of the air. It further consists of a suitable crate or cage constructed of incombustible or lire-proof material and adapted to contain a quantity of coal and to' be placed at any convenient point of the kiln, the load being built up around it. l y

In'the accompanying drawings, forming a part of this specification, and on which like letters of reference indicate corresponding features, Figure 1 represents a longitudinal vertical section of my improved kiln; Fig. 2, a transverse vertical sectional view of the same. In the drawings, the letter A indicates the basisor foundation of my improved kiln, the same being constructed of clay or cement, and the letter B indicates a series of longitudinal conduits or air-passages constructed ot' tubular tiles placed in the body of the base. Running transversely through the foundation A of the kiln is a series of air-conduits, G, formed of the same material and constructed in the same manner as that above described. This series of conduits is located below thelevel or plane of the bed of the kiln, and is so situated adapted to tit snugly' within the conduits, and

provided at any suitable point with acrossrod, g, the latter serving to engage with a suitable rod, H, by means of which the said valve is moved along the conduit in such manner as to entirely or partially close the communication between the longitudinal and transverse conduits, the object of which is also to provide for regulating the influx of air.

The letter I indicates the walls of the kiln, the same being of theordinary or any approved construction and built upon the foundation A, the latter being properly leveled off at a suitable distance below its surface for this purpose. Within these walls is built or arranged the load of bricks to be burned, the same being placed within the kiln in the ordinary manner.

In some instances, as will hereinafter appear, it is desirable to provide the kiln with fuel at one or .more points in the load, and for this purpose I construct a cage or crate, preferably of iron, in the form of grating or cross bars, within which is placed a quantity of fuel. The tire-arches are provided with doors L, by which they may be partiallyor wholly closed, according as circumstances may require.

I have ascertained that when the wind is blowing somewhat high the kiln on that side opposite to the point of the compass from which the wind is coming becomes relatively cooler than the diametrical side of the kiln. This frequently results in producing an inferior quality of brick, as those which occupy the portion of the kiln which becomes cooled by the wind, as above stated, do not receive sufficient burning, while-those on the opposite side are apt to be overburned. To prevent this difliculty I have arranged conduits in such a manner that, no matter in "what direction the wind is blowing, an increased amount of draft may be supplied tothe fire-arches, and agreater degree of heat maintained for the purpose of making the fire hottest near the side ofthe kiln which is sub- Q eeaoso jected to the cooling action of thewind. The sliding valves G are arranged so as to cut oi' the draft and direct it to the desired end of the fire-arches.

In some sections of the country the wind is known to blow from one point for aconsiderable length of time, and when this is the case the kiln being loaded has placed Within the load one or more of the fuel-crates K. This fuel becomes ignited by reason ot' the accumulated heat, and the blaze penetrates the mass when the bricks have become somewhat contracted, and thus serves to keep up the additional amount of heat required to counteract the cooling effects oi' the wind, this latter device being used only in extreme cases when the valve mechanism and conduits above alluded to are insufficient for this purpose.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In abrick-kiln, the foundation,constructed of clay or cement and provided with firearches having suitable doors, and a series of longitudinal and transverse conduits arranged at right angles with each other and communieating with the fire-arches, in combination with suitable valves whereby the draft may be *wholly or partially cut off at one or more sides, so that the air maybe fed from any quarter ot the compass, substantially as and for the pur-v pose specified.

2. In a brick-kiln, the combinationof the foundation, provided with tire-arches, and the series of air-conduits and regulating-valves with the removable fuel-crates, substantially as shown and described.

3. The combination. with a brick-kiln, of one or more removable fuel-crates adapted t0 be placed in the load or between the bricks being burned, whereby additional fuel and its resulting heat are supplied, as and in the manner set forth.

In testimony whereof Iafxmy signature in presence of two witnesses.

JACOB H. BEIDLER.
