SPECIFICATION forming part of Letters Patent N0. 472,697, dated April 12, 1892. Application filed Novemberv14, 1891. Seal No. 411,917. (No model.)
To @ZZ whom t may concern:
Be it known that I, SIMEON BUNN, a citizen make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention relates to improvements in furnaces for heating metals, such as iron and steel; and it consists in certain novel features hereinafter described and claimed.
The object of my invention is to provide a furnace which will permit the rapid handling of a large quantity of metal and in which one lot of bars may be removed from the furnace or inserted thereinto while a different lot is being heated.
A further object is to provide means for controlling the circulation of the heated currents through thefurnace.
These objects I accomplish by the use of the mechanism illustrated in the accompanying drawings, in which- Figure l is a sectional view of a furnace constructed in accordance with my invention. Fig. 2 is a detail side view of the valve or damper, and Fig. 3 is a detail perspective View of the ring which supports the end of the damper. Fig. 4 is a detail vertical section through one end of the damper, showing the operating mechanism and the supportingrollers.
The body of the furnace A is constructed of bricks or other suitable material in the usual manner, and is provided with a central fire-chamber B, from which extend the lateral beds C to support the metallic bars. The fire-chamber is provided with the usual gratebars D and the ash-pit E, as shown, and below the iioor of the furnace I form a tlueF, which extends across the entire width of the furnace and communicates at its ends with the vertical iiues G, which extend up to the beds C, as clearly shown. In the end walls of the furnace I provide the air openings or checkers H, which admit sufficient air to the flues F and Gto maintain a perfect combustion.
The chimney rises centrally fromthe roof of the furnace, and is constructed of any suitable, material, being reinforced at its lower end by the columns I. Between the chimney and the dre-chamber and i-n the plane of the lateral beds 0,1 arrange the damper or valve J, by which the heated currents are caused to pass over one or theother bed, as may be desired and as will be fully set forth hereinafter. This damper is composed of two circlilar plates or disks K, arranged at the ends of the furnace and provided on their inner faces with the! substantially V-shaped anges or ribs L, to which I secure the ends ofthe iirebrick partitions M, said partitions extending the entire length of the furnace and being provided with theV longitudinal passages M', which register with the `openings N in the 'plates or disks K and through which and the said openings I pass the pipes Oto receive and hold water, and thereby prevent the damper and pipes from being overheated. The ends of these pipes are threaded to receive securing-nuts, so that the end disks may be forced together, and the damper thus secured in position, and they join attheir ends the branch pipes P, which communicate with the water-supply. The disks K are provided on their outer sides with the annular anges Q,
on which I form the racks R, which are engaged by the pinion S, mounted in suitable bearings on the end walls of the furnace, so that lthe damper may be readily turned into the proper position. Small rollers T are mounted in the end wallsy of the furnace to support the damper and enable it to turn readily and easily, when desired.
The operation of the furnace will be readily understood. The bars of iron or steel are placed on the lateral beds and a iire is kindled in the ire-charnberin the usualmanner. The damper is turned so as to bring one edge down to the plane kofthe upper edge of the bridge- Wall on one side, and the hot air and products of combustion will be thus directed over the bed on the opposite side. They will pass over this bed and then down the iiue G into the bottom horizontal return-fine. Thence they will pass up the vertical flue at the opposite side of the furnace and'then over the IOO of metal is to be treated, as both beds can be n filled and the iire started. The metal on the' bed over which the heat first passes Will be raised to'a high temperature, and at the same time the temperature of the other lot of metal will be raised,but to a lesser degree. When the first lot of metal has been sufficiently heated, the damper is turned so as to cause the heat to pass through the furnace in the contrary direction,thus permitting the second lot of metal to be thoroughly heated While the irstlot is being removed from the furnace and a fresh supply placed therein.
From the foregoing it Will be seen that no time is lost in changing the supply of metal to the furnace, and aJarge quantity of metal can be treated in a comparatively short time.
My furnace is very siihple in its construction and its advantages are thought to be obvious from the foregoing description, taken in connection with the annexed drawings.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
l. Afurnace for treating iron and steel, having a central fire-chamber, lateral metal-supporting beds extending therefrom, flues leading from the ends of said beds, and a rotary damper above the fire-chamber and between the said beds, adapted to divert the products of combustion from either bed.
2. A furnace for treating iron and steel, having a central fire-chamber, lateral metal-supporting beds extending therefrom, vertical vflues at the ends of the 'said beds, communicating with the spaces above the same, a bottom return-flue passing below thebeds and connecting the said vertical ues, an escape flue or chimney, anda damper arranged between the beds and adapted to divert the products of combustion from either bed.
3. The combination, with the furnace having the central lire-chamber, the lateral beds, and tlues to carry the products of combustion from said beds, of the rollers mounted in the end Walls of the furnace and the rotary damper resting upon the said rollers and extending over the lire-chamber and adapted to divert the products of combustion from either bed.
4. The combination, With the furnace having a central {ire-chamber, lateral beds extending therefrom, and flues leading from the said beds, of the rotary damper arranged above the fire-chamber and adapted to divert the products of combustion from either bed and consisting of end disks mounted in the end walls of the furnace and a substantially V- shaped partition secured to and extending between the said disks.
parts together.
In testimony whereof Iaflix my signature in presence of two witnesses.
