FU RNACE-TAP.
SPECIFICATION forming part of Letters Patent No. 501,351, dated July 11, 1893. Application filed November 10. 1892. Serial No. 451,512. (No model.)
T0 a/ZZ whom t may concern:
Be it known that I, EDWARD PAYsoN MATH- EWSON, of Pueblo, in the county of Pueblo and State of Colorado, have invented a new and Improved Furnace-Tap, of which the following is a full, clear, and exact description.
The invention relates to furnace taps such as shown and described in the Letters Patent of the United States No. 483,936, granted to me October 4, 1892. v
The object of the present invention is to provide a new and improved furnace tap, which is simple and durable in construction, can be readily applied on any furnace now in use, and is arranged in such a 'manner as to prevent any undue chilling of the matte.
The invention consists of certain parts and details, and combinations of the same, as will be hereinafter described and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 isV a front View of the improvement. Fig. 2 is a transverse section of the same on the line 2-2 of Fig. l. Fig. 3 is a sectional plan view of the same on the line 3 3 of Fig. 2. Fig. 4 is an enlarged sectional front view of amodied form of slag spout on the line 4-4 of Fig. 5. Fig. 5 is a transverse section of the same. Fig. 6 is an enlarged front view of a modified form of casing; and Fig. 7 is a sectional side elevation of the same on the line 7-7 of Fig. 6.
The furnace on which the improvement is applied isrof the usual construction and is provided with the hearth or crucible A, on which is mounted the bosh B, formed of a series of water cooled sections C, and with the tuyere openings D, as plainly illustrated in On the front of the furnace is arranged a casing E, formed with front and side walls and connected at its inner open end with an opening F, leading tothe interior of the furnace A at the hearth A', as plain-ly shown in Fig. 2. The front of the casing E is formed at the bottom with an inwardlyprojecting extension E', formed with a matte hole E2, arranged directly below the lower end of the bosh B and extending into the opening F near the inner end thereof, so as to bring the said matte hole as near into the furnace as possible to prevent chilling of the matte, as it Hows from the furnace through the said matte hole E2 into the matte trough G, extending outward to carry or guide the matte to a suitable receptacle or channel.
yOn the front of the casing E directly above the extension E is formed acleaning hole E3, through which a rod may be thrust to the inside of the furnace to bar away congealed stuff around the tuyeres, or in the Crucible. A water cooled partition H, extends in the opening F in front of the upper part of the casing E, the bottom of the said partition being about in alignment with the top of the cleaning hole E3. This partition may be a separate piece as shown in Fig. 2, or it may be a part of the front section of the water cooled bosh B.
In one side of the casing E and near the top of the same is formed a slag outlet opening E4, through which the slag passes to a chute I, for carrying off the slag to one side of the furnace. As illustrated in Figs. 4 and 5, this chute I may be made adjustable and for this purpose is fitted to vslide vertically in guideways J, formed on the side of the casing E. The slag hole E4 is for this purpose made elongated as plainly shown in Fig. 4, so that for a variation of blast pressure, the slag outlet can be made higher or lower by adjusting the spout vertically as required. Thus,if the pressure increases, the chute I can be raised and if the pressure decreases, is correspondingly lowered. The casing E is Water jacketed and preferably made of cast iron and is adapted toV be readily applied to any furnace now in use.
As shown in Figs. 6 and 7, the front wall of the casing can be provided with a door K for facilitating the cleaning of the casing and to have access to the interior of the furnace in case of serious derangement therein.
It will be seen that by forming the extension E containing the matte hole, the molten mass can readily pass through the openingF to the matte hole E2 without danger of chilling the molten matte.
IOO
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A furnace tap provided with a casing in communication at its rear open end with the interior of the furnace, the front of the said casing being provided with an inward eXtenson containing the matte hole, said matte hole being arranged below the bottom edge of the Water -cooled bosh, substantially as Shown and described.
2. A furnace tap provided with a casing in communication at its rear open end with the interior of the furnace, the front of the said casing being formed with a rearward eXtension containing a matte hole, the front being also formed with a cleaning hole located above the extension, and one side of the said casing being formed with a slag hole to permit the escape of the slag, substantially as shown and described.
3. In a furnace tap, the combination With a casing formed in its front with a rearward extension containing the [natte hole, of a chute into which discharges the said mat-te hole, and a trough arranged on the side of the said casing and into which opens the slag hole, substantially as shown and described.
