IMPROVEMENT IN BRiCK-KILNS.
specification forming part of Letters Patent No. 187,217. dated February 13, 1877 application l'iled November 27, 1876.
' chamber which communicate with the arches ofthe kiln, by means of iiues and openings so arranged with relation to the fire-chamber that the heat can be controlled, directed, and distributed at the will of the operator, said furnace being constructed in and Within the walls of the kiln.
To enable others skilled in the art with which my invention is most nearly connected to construct and use it, I will proceed to describe its construction and operation.
In the accompanying drawings, which form part of my specification, Figure 1 is a front elevation of my improvement in fur-l naces for brick-kilns. Fig. 2 is atop view or plan of the same. Fig. 3 is a vertical seetion of the same, at line g/ of Fig. 1. Fig.4 is a horizontal section ot' the same, at line y of Fig. 3. Fig. 5 is a vertical section of The object oi' my present improvement in furnaces for brick-ki1ns is to provide a cheap and efficient means for burning brick constructed of clay which does not easily yield to the action of heat-that is to say, in the language of brick-burners, hard to burn.77 The unburned brick next to the front walls of the kiln, when constructed of clay which is hard to burn, requires a very great heat, having velocity, and it is of the utmost importance that the heat be applied in a very direct manner with the shortest travel, so that the interstices between the brick, and between them and the kiln-walls, will be illed with an active and penetrating heat. To this end I construct the furnace in and within the kilnwalls, and furnish the crown of the furnace or fire-chamber with openings and ilnes that will allow the heatirom the tire-chamber to travel directly up the inner face of the kilnwalls, and fill the interstices next to said wall with heat having velocity and penetrating power, which is greatly increased by commingling cold air with the gases ot' theiur.- nace in mannerjLand by the meansfwherelnaiter described.
[n the accompanying drawings, A represent the kiln-walls, which are of the ordinary construction. The fire-chamberA is provided with a grate, B', door C', susceptible oi' being raised by a pivoted lever, as indicated at x, for
the purpose of admitting a iiow of air under the lower edge oi' the door and over the surface of the fire on the grate. The bridgewall B is provided with an air-chamber, n, which communicates with the re-chamber A by means of openings o. Air is conducted into the chamber n by the flues m. Air is conveyed into the re-chamberby means of the lues n and openings j, which form a series of communications between the iues h and the chamber A. At the back end of the firechamber A, and above the bridge-wall B, are two curved and converging walls, l, in each of which is an air-chamber, r, which communicates with the rear part ofthe fire-chamber A by means of small openings k. Air is conducted into the chambers r through the medium of the dues t'. The crown D of' the rechamber A extends above the licor y ot' the kiln, and is provided with an opening, U, having a valve, e, operated by a rod, s. By means of this opening and valve the flow of heat can be regulated with relation to the brick next to kiln-walls, in conjunction with the opening U and valve e. ,The nre-chamber A is furnished with ues f,`h aving valve g, which ilues and valves are for like purpose as that of opening O and valve e. By making a series of openings instead of a single opening in the crown D, as indicated at D in Fig. 2, the valve e may be dispensed with 5 but as I propose making this arrangement the subject of another application for Letters Patent I will not here further describe it. By the arrangement of air-lines communicating with the fire-chamber, air is commingled with the gases of the furnace, which results in complete combustion, and generates an intense heat, which is distributed by means of the Opening C, iiues f, and controlled by valves e g, for the purpose herein specified.
Having thus described my improvement, what I claim as of my invention is- 1. In a furnace for brick-kilns, the firechamber A, bridge-wall B, crown D, extending above the floor of the kiln, and havin-g an opening, C, provided with a valve, e, the whole being constructed and arranged Wit-h relation to the interior of the kiln and its Walls, substantially as hereinbefore described, and for the purpose set forth.
2. In a furnace for brick-kilns, the rechamber A, hollow perforated bridge-Wall B, opening C in the crown D, furnished with a valve, e, and lines f, having valves g constructed and arranged with relation to the interior of the kiln and its Walls substantially as hereinbefore described, and for the purpose Set forth.
3. In a furnace for brick-kilns, the firechauiber A, hollow perforated bridge-Wall B,
opening C in the crown D, furnished with a valve, e, ues f having valves g, andl ues h land i communicating with the fire chamber A by means of perforationsj and k, constructed and arranged with relation to the interior of the kiln and its Walls substantially as hereinbefore described, and for the purpose set forth.
4. In a furnace for brick-kilns, the firechamber A, hollow perforated bridge-wall B, Opening C in the crown D, furnished with a valve, e, fines f, having valves g, fines h and 'i communicating with the fire-chamber A, and the converging walls l at the rear end of the fire-chamber, constructed and arranged with relation to the interior of the kiln and its Walls substantially as hereinbefore described, and for the purpose set forth.
