ANNEALINc-FURNACE.
SPECIFICATION forming part of Letters Patent No. 494,597, dated April 4, 1893.
Application iiled August 29, 1892. Serial No. 444,442. (No model.) Patented in England June 2, 1891, No. 9,342.
To @ZZ whom it may concern,.-
B'e it known that I, JOHN HENRY Roenes, tin-plate manufacturer, a subject of the Queen of Great Britain, residing at Glyncoed, Llanelly, England, have invented certain new and useful Improvements in Annealing-Furnaces, (for which I have received Letters Patent in Great Britain, No. 9,342, dated June 2, 1891,) of which the following is a specification.
The object of my invention is to improve furnaces used for annealing more especially for annealing tin and terne plat-es. For annealing the plates I employ three or more but preferably three furnaces ranged in the arc of a ciicle-eachadapted to be heated by gas from a gas producer introduced together with air at one end while the products of combustion are led away by chimney outlets at the other end. During working, one furnace at a time is thus heated. The air for supporting combustion in this furnace is led through the furnace last heated so that the air is heated and the furnace and the pots containing` plates within it are cooled. The third furnace is opened and the boxes Within it which contain plates that have been annealed are removed and fresh boxes containing plates which are to be annealed are placed into it. The furnace is then closed and when closed may be heated by leading through it the products of combustion which are passing away from the furnace that is being fired. The furnaces are set end to end and occupy only part of a circle. In the remainder of the circle can be ranged two series of boxes, one series of boxes which have been removed from one of the furnaces can be cooling, while the other series can be emptied and refilled. The furnaces are formed with the openings in them through which they are to be filled and emptied all in the side which is toward the center of the circle. At the center of the circle I place a crane with horizontal radial arm which can be swiveled around a central post to bring its outer end to any point in the circle and can also be extended or contracted and its outer end raised or lowered to place boxes of plates into or take them from the furnaces.
Figure l is a plan View partly in section of the series of furnaces and central charging crane. Fig. 2 is a plan in section of one of the furnaces and a portion of the next adjoining furnace. Fig. 3 is a vertical section on the line A B Fig. 2. v
A A2 A3 are three furnaces ranged in the arc of a circle and constructed with openings AX on the inner side through which the boxes of plates can be charged into the furnace or withdrawn. These openings have doors which are closed while the furnace is being heated.
Each furnace at its end opens into acharnber B from which an outlet flue O passes to a chimney X.
C is a valve or damper between the end of the chamber and the outlet due.
At the other end of the furnace is a flue E kept supplied with gas from a gas producer at Z.
E are openings from the gas supply flue into the furnace.
E is a Valve by which ,the passage of gas to these openings can be controlled.
D is a chamber between the chamber B at DX is a valve by which air can be admitted to the chamber D and passage D.
. I is a flue from the exit end of the last of the assemblage of furnaces to the chamber C at the firing end of the first furnace.
When any one or other of the furnaces say the furnace A has been charged with boxes of plates that are to be annealed and the furnace has been closed, heated gases from the preceding furnace A3 which is at that time being fired are led to it through the passage I which connects them and pass off from the opposite end of the furnace by the chimney outlet C at that end. Afterward when the firing of the furnace A3 is discontinued and the valve EX in the passage E through which gas was being supplied to this furnace is closed the valve or damper B at the exit end of the furnace A2 is also closed and the cold air inlet Valve at the firing end of the furnace A3 is opened so that cold air can then pass into the furnace A3. In its passage through the furnace the air becomes heated and passes in its heated state into the furnace A. At
IOO
the same time gas is admitted to this furnace and the firing of the furnace is proceeded with. When the furnace A2 has been charged and closed the chimney outlet between the furnaces A2 and A3 is opened by opening the valve GX and the one between A and A2 is closed-the heated gases from the furnace A will then be led through the furnace A2 so as to heat its contents.
F F and G G represent boxes containing plates the boxes F may be boxes which have just been removed from one of the furnaces and set out to cool. The boxes G may be boxes which have been filled ready to be charged into a furnace.
H is a revolvingr crane the post of which is concentric with the are in which the furnaces are ranged.
1. The combination of three or more furnaces arranged in the arc of a circle end to end, each furnace having at one end a flueE connected with a gas producer and which delivers gas to the furnace, and at its opposite end a chamber B, connected with a chimne7 or exit, an air chamber interposed between the flue E, and the chamber B, an opening D for admitting cool air to said chamber, and valves for controlling the entrance and exit of gas and air, substantially as set forth.
2. The combination of three or more furnaces arranged in the arc of a circle end to end, each furnace having at one end a fine E connected with a gas producer and which delivers gas to the furnace, and at its opposite end a chamber B, connected with a chimney or exit, an air chamber interposed between the flue E and the chamber B, an opening DX for admit ting cool air to said chamber, valves for controlling the entrance and exit of gas and air, and a crane pivoted within the arc of furnaces and arranged to deliver blanks thereto, substantially as set forth.
3. The combination of three or more furnaces arranged end to end, each having at one end a flue E, connected with a gas producer, and a passage E', through which gas is projected downwardly into the furnace upon the blanks, an air chamber D, having a flue D', delivering air to the furnace above the passage E', a chamber B, at the opposite end of each furnace, and connected with a chimney, and a valve or gate BX, for opening and closing communication between the exit passage B and the air chamber D.
4. The combination of the furnaces A A2, arranged end to end, a gas chamber E, at the entrance end of each furnace connected with a gas producer, a chamber B, at the end of each furnace connected with a chimney, an air chamber D between the entranceEof one furnace and the exit chamber B, of the other furnace, a valve or gate BX between said chambers B and D,avalve for controlling the entrance of cool air to the chamber D, a passage D from the chamber D to the furnace A2, and a flueEfor the passage of gas to the furnace A2 from the gas chamber E.
5. The combination of two or more furnaces arranged in the arc of a circle, openings on the inner side of each furnace through which articles may be inserted into or withdrawn from the furnace, a chamber B, into which the exit end of each furnace opens, a chimney fine C, fitted with a valve CX leading from each chamber B, an opening fitted with a valve BX from each chamber B, into the firing end of the next furnace, a gas flue E, tted with a valve EX passing across the interior of each furnace at a short distance from the firing end, a passage D between the top of this fine and the top of the furnace, passages E for gas to pass into the furnace from the gas fine E and an opening fitted with a valve D for admitting cold air to the passage D.
