SPECIFICATION forming part of Letters Patent No. 294,684, dated March 4, 1884.

Application filed December 1, 1883.

To a/ZZ whontit may concern,

Beit known that I, HERMANN SCHULZE- BERGE, of Rochester, in the county of BeaverA thereof.

My invention relates, particularly, to that class of Bessemer converters known as fixed or Swedisln and it consists in an improved apparatus for regulating and4 controlling the blast through the tuyeres, and of preventing the passage of the molten metal therethrough.

To enable others skilled in the art to make and use my invention, I will now describe it by reference to the accompanying drawings, in which- Figure l is a vertical section of a converter. Fic'. 2 is a longitudinal view ofthe tuyere and stopper, also in vertical section. Fig. 3 is a view of a detail of construction.

Like letters of reference indicate like partsv in each.

. The converter a is provided with a wind box or trunk, b, blast-pipes c, feed-spout with cover d, tapping-hole c, einder-notch f, and throat g, all of the usual construction. The tuyeres h are each provided with an external chamber or pipe, t', secured to the outside of the shell of the converter, and having a suitable opening, i', to which the blastpipes c are connected. The inner ends of the tuyeres h are of flaring or other form, as at h', to form a seat for the stopper k. The stopper k is of proper form to close tightly against the seat h', and is provided with a stem, k', which extends through to the pipe or chamber z', and through a stuffing-box, i2, situated at its outer end. The outer end of the stem 7c is pivotally connected to the lever Z by means of the link Z, the lever being pivoted to a bracket, l2, or other suitable support. As shown, the stopper 7c is constructed with a cast-iron part, k2, to which is attached a facing, 7c3, of refractory material. The facing is a brick formedv with a metallic core, k, and a nut, 765, molded in. The end of the stem k is threaded, so that it can be screwed into the nut, and is provided with a collar,

la, against which the metallic part k2 is tightly.

drawn when the stem is properly screwed into the nut.

I do not limit myself to the formand construction of stopper shown and described, be cause, if desired, it may be made entirely of refractory material and of other fornts, and the stem It" secured thereto in other ways, as is obvious to one skilled in the art.

By the use of this improvement the size of the tuyere-openings can be regulated as required, and the tuyere may be tightly closed when desired, so as to prevent the passage of the molten metal therethrough. The tuyeres may be placed in the bottom of the converter, if desired.

To facilitate the insertion and removal of the stoppers, the tuyere is composed of or surrounded bya taper-shaped brick, m, which is preferably made longer than the recess in which it is placed, so that it may be forced and held tightly to' place by its retaining` llange or plate m and bolts m, or other suitable fastening devices.

Other means of securing the sections m in place may be adopted, as will be evident to those skilled in the art, which will enable the removal of the internal stoppers.

, The blast-pipes c are provided with a union, c', or other joint, so as to permit the detachment and removal of the blast-chambers i when it is desired to take out the tuyeres and valves.

The retaining ange or plate m can be provided with an inward shoulder or projection,

to bear against the end of the tuyere-section m, in which case the end of the latter need not project beyond the side of the converter, but would be forced tightly to its seat by the inward projection when the bolts m2 were IOO sent or unseat l'hem :it will during the opern- In testimony whereof.'
