GEORGE HATTON, OF HAGLElQilOUNTY OF YVOROESTER, ENGLAND.

CONVERTER FOR THE MANUFACTURE -OF IRON AND STEEL.

SPECIFICATION forming part of Letters Patent No. 308,963, dated December 9, 1884.

Application filed September 15, 1884. (No model.) Patented in England June 27, 1884, X0. 9,500.

.1 0 ail whom, it may concern:

Beit known that I, Gnonen Hn'r'ron, a subject of the Queen of Great Britain, residing at Hagley, in the county of lVorcester, Eng- 1 land, have invented certain new and useful Improvements in Converters Employed in the Manufacture of Iron and Steel, (for which I have applied for Letters Patent in Great Britain, my application bearing date the 27th day of June, 1884:, and being numbered 9,500, but have not yet obtained the grant of such Letters Patent,) of which the iollowing is a specification.

In converters employed in the manufacture of iron and steel as usually constructed and arranged, considerable injury is frequently done to the blast boxes and valves through which blast is supplied to the tuyeres on account of the leakage of the metal through the converter-lining; and the object of this invention is to provide against such inj ury, and also to simplify the lower part of the convertor, (that is, the part containing the tuyeres and the part of the lining liable to be most readily burned out,) which is in this case re movabl.e,by omitting from such lower part the usual blast chamber or boxes. I attain this object by making the lower part of the con verter, containing the tuyeres and that part of the lining which is liable to be most rapidly burned out, removable from the upper part of the converter, substantially as has been sometimes heretofore adopted; but the blast receiver or boxes, with any necessary blastvalves, are carried around the upper part of the converter, so as to dispense enti rel y with a blast chamber or boxes around the lower part thereof, and the blast is conveyed there from by means of a separate supply-pipe to each tuyere. These supply-pipes are constructed so that they may be easily disconnected at any convenient point in their length, in order that the lower part of the converter may be readily removed for replace ment with a duplicate.

My invention will. be clearly understood by reference to the accompanying drawing, which of a fixed converter carried by columns, so as to admit of the ready removal and replacement of the bottom.

A A are the columns supporting the upper part, B B, of the converter. The lower part, 0, of the converter is held by means of a flange or angle ring, D, and bolts therethrough to a flange or angle ring, E, at the bottom of the upper part of the converter, so that the lower part, (1, may be readily removed from the upper part and replaced with a duplicate. The lower part, G, contains the tuy'eros, of ganister or other refractory material, one of which is shown in section at F, and also that part of the furnace-lining which islialole to be most quickly burned out.

G G are air chambers or boxes carried with the upper part of the converter, and therefore remaining fixed, while the lower part is removed for relining.

H is a plain ball'ler -valve for regulating the passage of blast to a tuyere, and J J, &c., are blastpipes. A separate pipe, J, passes down from each blast chamber or box G to each of the tuycrcs. Each pipe J forms a ball-andsocket or universal joint with the 5 short pipe K, containing thevalve, and this j joint is tightened up by means of a bridle or strap, I1, and setscrcw ll]: thereunder, as shown. llach pipe .l' is connected, also, by

means of a flangejoint, N, with a mounting,

0, on the casing of the lower part, 0,01 the converter. The holes a a through the flanges at a joint, N, are elongated in vertical direc-' tiou, and are open to the edges of the flanges, as shown, so as to allow, respectively, for one of the flanges not being exactly vertically opposite to the other, and to facilitate the removal of the bolts. K is the usual tappinghole.

When it is desired to remove the lower part, 0, ol' the converter, each flange-joint N is disconnected, and each setscrew M at the bottom of a bridle, L, is slackened, and the pipes lettered J are then pulled back at their lower ends to be as clear from the mounting O as may be desired, and are held in such position by tightening up the set-screws M. \Vhen a converter-botton1, G, has been re moved and replaced, the pipes J are of course again connected up.

I) Z) are sight and cleaning holes forthe tuyeres. The joint between the upper and lower parts of the converter is made perfectly sound by ramming ganister in around the annular wedgeshaped space 0, formed between the bottom of the upper lining and the top of the lower lining.

P P are rails upon which a trolley is run for bringing in and removing converter-bottoms, and such trolley may, if desired, be raised and lowered by means of a hydraulic ram or any convenient means, to facilitate fixing and unfixing the bottoms. The columns A A are shown broken in their length for convenience of illustration. Sufficient room is allowed, preferably below the converter, to admit of the bottom being lowered clear of all obstructions to its removal. It will now be seen that the blast chambers or boxes remain in position upon the removal of the lower part of the converter, and that, if during the working of the converter any metal escapes through the lining of the lower part thereof, such metal cannot find access to the blast chambers or boxes or to the valves immediately thereunder. The removable bot tom is also much simpler and less expensive than when an air chamber or boxes are attached thereto.

My invention has been described and illus trated specially with reference to a fixed converter; but it will be readily understood to be applicable also in the case of a Bessemer or tipping converter, in which (as is sometimes done) the tuyeres are arranged in the side of the converter for the purpose of blowing with a low-pressure blast, instead of in the bottom,

as is usual when a high-pressure blast is em- 35 ployed.

Having thus stated the nature of my said invention and particularly described the manner of performing the same, I declare'that what I claim is 0 1. In a converter employed in the manufacture of iron and steel, the combination, with the removable bottom ofthe converter, containing the-tuyeres, of the upper part of the converter, carrying the blast-chamber, and 45 means, substantially as described, for carrying the blast from the blast-chamber to the tuyeres, substantially as and for the purposes set forth.

2. In a converter employed in the manufacture of iron and steel, the combination of the blast-boxes G with the blast-pipes J and the removable bottom 0, all constructed and arranged substantially as and for the purpose herein described and shown.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
