IMPROVEMENT IN BRICK-KILN FURNACES.
Specification forming part of Letters Patent No. 205,851, datcd July 9, 1879; application filed J une 21, 1877.
To all whom 'it may concern Be it known that we, JACOB FRANZ and JOHN C. STEVENS, of Allegheny, Pennsylvania, have invented a new and useful Improvement in Brick-Kiln Furnaces, which improvement is fully set forth in the following specication, reference being had to the accompanying drawings.
Similar letters of reference indicate correspondin g parts.
In the accompanying drawings, which form a part of this specification, Figure l is a front elevation of our furnace, showing in the lefthand division the outer or face wall and doors, and in the right-hand division of the figure a vertical section of the furnace as cut on the lines x fc m :c in Fig. 2. Fig. 2 is a horizontal section of the furnace, showing the chambers as cut along the lines y y in Fig. 3; and Fig. 3 is a longitudinal section of one of the furnaces as cut on the lines y y in Fig. 1.
A represents the back walls of the furnaces. a. a a are posts for maintaining the roof of a kiln. B shows the front or face of the furnace. b b are doors in the walls B. b b are draft-openings under the doors b. O O are liuc-openings into the walls of the combustionchambers. c c are air-passages for draft. c c are openings of the ilues cinto the mouth of the flues D. B B are ash-pits. D D are converging lines of the furnaces. D1 is the combustion-chamber. D2 D2 are the lines D continued. el l are grate-bars. E is the base of the furnaces.
Our furnace is constructed mainly of firebrick on the interior and ordinary buildingbrick on the outside. The doors and gratebars should be metallic. Beneath the doors b are draft-openings b'. rEhe combustion-chamloer D1 is properly arched over from the front backward about the distance of the grate-bars, where the wall A is commenced. These doors b, side walls of chamber D1, grate-bars, &c., are of ordinary construction. Beneath the grates are the ash-pits B B.
Our furnace has a series of combustion-chambers, D1, and in the main are constructed alike. ln the walls along the outside of these chambers are single flue-openings C for air. These iiues extend along the centerof the outer walls till they reach theback end ofthe chamber D 1 at which point the iiues cease to run in ahorizontal line and rise vertically over the chamber D1 to the dome, and there connect with a similar flue from the other side of the arch. This latter is a llue along near the center of the bridgewall between two of the chambers D1, as seen in Fig. l. It will be seen that the iiues in the walls between two of the furnaces separate after entering the wall, and form two distinct flues between these chambers D. At the top and along each of the sides of the arch of the flue D, the air passing along these several flues c, nds egress into the lines D through the openings c c. In this way each of the arches of these chambers D1 has its lue c and due-opening c in the iues D. These flues D are so constructed as to converge from the sides and dome till a small square iiue, D2, is formed, and this leads the ame oft' into the kiln proper.
Ourfurnaces are constructed on aplane with the floor of the kiln, so that the llame passing through the flue D2 has no descent or ascent to make, but goes to the desired place in the flues of the kiln on a straight line.
When thus constructed, and the brick properly placed in the kiln and ready for burning, the operation of our furnace will be as follows: rlhe proper fuel will be put in the combustionchamber D1 and lire set thereto. The doors will be closed, and, after the fire has fairly started, the lines C O will be opened. Air will then pass into the same and along through the walls on the outside and between the furnaces, traversing the distance back to where the flue begins to ascend. The air passes up the sides of the walls of the chambers and on up to the dome, and nds exit into the iame at about the divergiug point of the iiue D. Here the air will meet the flame of the combustion-chamber D1, and will aid in producing heat.
We make the iiue D diverging, as seen in Figs. l and 2,in order to concentrate the ame, thus making the heat more intense before it passes into the kiln.
We make the double ilues between the furnaces or chamber D1 for the reason that by this means an equal proportion of air will be given the flue to the right and the one to the left, thus atl'ording a more equal distribution of air into the mouth of the tlues l).
We notice that the tine-openings in similar furnaces to ours are so placed that the ashes and cinders in the combustion-chambers are likely to, and do in fact, often close them up, thus impedingdraft. For this reason we have our Hue-openings in the comhustion-chamber at the top, where they will not be stopped up by any substance, but will always be clean and ready for action.
Having thus described our invention, what we claim, and desire to secure by Letters latent, is-
1. In a brick-kiln furnace, the double titles in the Walls between the several furnaces, for
the purpose of conveying an equal quantity of' air into the furnace-chambers in aid of combustion, substantially as described.
2. In a furnace for brick-kilns, the double tlues between the several furnaces terminating in the dome of the combustion-chambers in the openings c c', in combination with said conlbustion-chamber DI and tluc 1)7 substantially as described and shown.
In testimony that we claim the foregoing we hereto set our hands.
JACOB FRANZ. JOHN C. STEVFNS.
