The Schedule referred to in these Letters Patent animaldngppart of the name.
To all whom lit may concern: y
Be it known that I, SILAS M. HAMILTON, of the city and county of Baltimore, and State of Maryland,
have invented certain Improvements in Brick-Kilns; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings making part of this specification, in which- Figure l is a side elevation.
Figure 2 is a horizontal section.
Figure 3 is avertical transverse section.
Figure 4 is a-.vertical section on an enlarged scale, showing the construction of the upper circulation fines in the green bricks.
The same letters are used in the several figures to indicate identical parts.
M-yimprovement relates to that class of kilns in which a seris of compartments are constructed in thebody of the kiln, which, wheniilled with green v brick, are
snccessivelyiired, the waste heat tiom one being drawn.
through the next compartment in ,the series, for the purpose-of carrying away the-water smoke and drying the bricks preparatory to'burning; and
My invention consists in a novel arrangement of the compartments and of the parts for carrying on the usual operations, to be hereinafter set forth. `In the annexed drawings-- I have shown at A the wall of a permanent rectanguiar kiln, said wall forming a single apartment; which,
however, Amay be divided into a series of compartments by sliding doors. 1 l
B B are the furnaces, and B' B' the tircgrates. The fires are builtin the furnacesin the ordinary manner, and the green bricks schuilt as to form arches, and
to leave interstitial spaces for the free cil'culation of the draftfthrough the 4mass. ot' green bricks.
Steam generators (J are built intoihe permanent walls of the kiln, or constructed separately therefrom with independent furnaces, as may be preferred. f
From .these boilers pipes Cl conduct jets of steam to be discharged intol the furnacesabovc the fires, to
force the draft through the body ofthe green bricks in i the kiln. r
Other pipes, C, are carried from the boilers' and made to discharge jets of steam into the chimneys D. In orderthat the cover of the kiln may be removed the st'ea-m-pipes'C2 are made to'turn upon swivel-joints,
'which permit the horizont-al section of the pipes Cz to be turned so as to pass the jets from the branch pipes into the chimneys, or swung out of thc way.-
The. chimneysl propose to make of fire-clay, like Y ordinary*chimney-pots, so that they may be removed from place to place as desired. 4'.lhey should be Aconstructed with slots in the sides, so as to permit the turn Hue F, which I prefer to branch jet-pipes'to be inserted when the holes may be filled withvet clay. 5
Vertical openings E are formed at intervals in A the walls A, through which sliding metaliicdoors may be passed-to cut olf entirely the connection between one part of the chamber and'another.
The chimneys will be placed on the top ofthe com- Y parturents, nearly above the sliding partitions, so that by inserting the 'steam-jets the draft may beearried out of the' compartment at that point.
; The two ends of the kiln are connected bythe recarry under ground. This due will be closed by valves or doors, so that, when desired, by opening the doors the draft may be drawn from the compartment at one end to that of the other; and by this means a continuous Voperation be conducted, the chambers being successively fired.
This return iiue passing under the floor of the kiln` ,will in its passage impart heat to the lowest stratum of bricks in the compartment.' y
Whe'nthe kilns vhave been filled they are to be covered with bricks and clay; piled upon them, to prevent the upward passage of the draft except through the chimneys.
In constructing the'covering care should be taken to form longitudinal flue openings along the pper surface of the br'icks-,as shown at G in fig. 3, for the purpose of inducing a free circulationV of heat over the entiredlpper portion f the kiln, and thus equalizing the heat in thev top thereof. l
The steam-pipes()1 are carried within the chamber of the -kiln into a super-heating pipe or coil, H, so that the jets of steam thrown into the furnace shall be jets of super-heated, not saturated steam.
In firing .the kiln I'propose to build the fires alternately in the furnaces at oppositesides of the kiln.
' In filling the kiln with green bricks fl propose to buildthem so as to leave spaces at,intervalsso as to divide the mass intoblocks of bricks, between, which there may be a free circulation of heat, and from these spaces the draft will'be carried in the ordinary mannen through the interstitial spaces between the bricks.
The .morabiechimneys may be inserted wherever it is desirable-to draw out thedraft. l What I claim, and desire to secure by Letters Pat nt is 1. A continuous kiln A, divisible into compartments bysliding doors, in combination with removable chimneys and steamdraft jets, substantially as set forth. y
2. `In combination with a continuous kiln and chimney D, the steam-pipe G2 arranged to swing on a joint, substantially-as set forth. i
3. In combination with a kiln vand steamget pipe,
removable slotted eliimneypots, 'substantially as and for the purpose set forth.
4. In combination wit-h the kiln A and steamdzaft jets, the upper circulation ues G built in the boi-ly of green bricks placed in the kiln, substantially as described.
5. In combination withthe kiln Aand its furnaces, .th jet-pipes C and super-heating pipes H, substan- 'tially ns set forth.
6. In combination with the kiln A, divisible into compartments, a. return ne F, carried Krom endl to gud under the lloor of the kilu, substantially as seb orth.
In testimony whereof, I have sig-nea my nnme to this specification in the presence of two subscribing witnesses.
S. M. HAMILTON.
