-To all vwhom it may concern: t
Beit known that I, JOSEPH OONLEY, a citi-` zen of the United States of America, residing at St. Joseph, in the county of Buchanan and State of Missouri,have invented certain new and useful Improvements in Brick-Kilns; and I do hereby declare the following to be afull,
clear, and exact description of the invention,- vsuch as will enable others skilled in the arttok zontal sectional view of a kiln constructed in accordance with my invention. Fig. 2 is a vertical section taken on theline wof Fig. l.
The kiln illustrated is a rectangular kiln with an open top.
The end wall A of the kiln is provided with furnaces for starting the fires, and the side walls at intervals are provided with doorways a a which are above the ground level and provide access to the kiln in stacking and removing the bricks.
In constructing the kiln I provide a main longitudinal flue O which extends from the end wall A to a cross-flue E located near the end wall A. This main nue connects by means of an underground flue C Y with a chimney or stack D which is located beyond one of the side walls of the kiln so as not to be affected by the heat generated in the kiln.
E E designate underground cross-dues which lead to draft openings e c located just outside the side walls and walled in to prevent dbris from entering the flues. These crossfiues do not extend directly across the kiln but diagonally toward the mainflue and meeting thereat. The angle of the cross-lines is toward the exit line C', and by this arrangement the draft toward the chimney is facilitated and a more convenient manner of operating the dampers or cut-OES in the upper part of the flues is provided.
. Adjoining the end wall A of the kiln is a ,straight flue E2 which extends through the side walls of the kiln and connects at its central portion with the main flue C. This ilue communicates with the interior of the kiln by means of the openings t" which are provided with dampers the operating rods of which ex-` tend through the end wall.
It will be noted that all the llues are under'.
, the fuel or for cooling the bricks should they become overheated and after they are burned.
The longitudinal or main fiue is provided at its intersection with the cross-dues with openings which lead into the interior of the kiln, and said openings are provided with dampers ff operated by rods f which extend through the side walls. The cross-fines E E are also provided with openings which lead into the interior of the kiln and are provided with dampers g operated by damper rods g. It will be noted that by disposing the cross-fines diagonally as shown the damper rods extend directly to and'beyond the side walls and will be on a line with each other horizontally so that the position of said damper rods will readily indicate the location of the dampers connected thereto. The main due is intersected to one side of each of thecross-lues by dampers or cut-offs h the operating rods of which extend through one of the side walls into the recesses provided for the outer ends of therods f g.
By the construction hereinbefore described the fines are located below the floor level of Y the kiln and the side walls can'be built in a substantial manner so that they will not be affected by the heat. Consequentlyakiln constructed in accordance with my invention is y The flue C' has a suitable cut-off c, located between the side wall of the kiln and the stack.
lnpractice the kiln is burned in sections,
'the iirebeing started in the furnaces at one end, and after the center of the kiln is reached by the fires the draft and water smoke are drawn back under"` the burning brick to the stack. The green brick is stacked to provide small longitudinalfiues"which are about nine" inches or the length of' one brick apart"` and` are about four inches wide and twelve inches high.
The fuel used to feed the fire is slack coal which is fed in small quantities from the top,
\ slack coal being preferred as it is at once converted into gasand gi'vesan intense and* uniform heat. t
Having thus described my invention, what I claimjas new, and desire to secure by Letters Parenti@ 1. In a down-tlraft kiln, the combination, of acentr'al longitudinal underground flue C which" communicates with t a draft v Stack through an exitiiue C', cross-fines EE which extendfrom the central flue diagonally to and beyond' theside walls and are provided with openingshwhich lead into the interior of the kiln, dampers br cut-osfor said openingsv the operating rods of Whichextend directly to the side `v'allsand'through the same,substantliall as Shown, andfor the purpose set forth'.
"2l Inf'a dowlnd'raftf brick kiln, the combination, of` a central longitudinal flue C, crossflues E E extending from the central iue di agonally to the side walls and through the same, the central flue and cross-fines communicating with the interior of the kiln through openings in the floor of the same, cut-offs located in said openings, the operating rods of which are located beneath the floor of the kiln and'exte'nd directly to andbeyoud th'e side walls of the kiln,'s'a`id1`*ods beingon the same horizontal plane, substantially as shown, and
for the purpose set forth.
3L In a down-draft brick kiln comprising inclosing walls constructed substantially as `shovvnand` provided at one end with a plurality 'offurna'cesg a central longitudinal flue which coinmunicateswith an exit flue leading to a drat`t-stack, a series of underground iiues which extend from the centralue diagonally' Witnesses;
