,TUYERE SPECIFICATION lforming part of Letters Patent N o. 261,782, dated July 25, 1882.

I Application filed October 24, 1881. (No model.)

To all whom it may concern:

Be it known that I, JACOB STOLL, of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented a new and useful Improvement in Tuyeres, ot' which the following is a. full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming partof this specification, in

' which similar letters ot reference indicate corresponding parts in all the tgures.

Figure l is a plan view of my improved tuyere. Fig. 2 is a sectional elevation of the same, taken on the line x a: of Fig. l; and Fig. 3, an end view ofthe tuyere.

My invention consists of a removable perforated and chambered face-plate or head, and ofjacketing the pipe leading from the blower, the face-plate or head being so perforated that aportion ot' the blast will be permitted to escape into the chamber formed by the jacket, thus preventing all danger of gases or dust from the forge entering the blower and all danger of the tuyere becoming stopped by melted slag or injured from heat.

A represents the pipe which leads from the blower. B represents the jacket, and C the face-plate or head. The pipe A is curved, as shown, and the end ofitis externally threaded, as shown at a, and projects a short distance beyond the end of the jacket B, so that the face-plate or head C may be screwed upon the to rest upon and form a good pipe A, so as joint with the end of the jacket, as shown in Fig. 2. 'Ihe face-plate or head is formed with the cham ber d, and its upper conical orrounded surface is perforated with numerous holes, c c, and its under or dat surface is perforated with the holes e e, which lead from the chamber d back into the chamber b, formed by the jacket around the pipe A. By this construction a portion ofthe blast from the pipe Ais deected from the chamber d back through the perforations e e into the chamber b, thus conducting oit' any gas or ashes which mightA enter the chamber from the forge through the chamber b, and thereby preventing its entrance to the pipe A, through which it might iind its way to the blower and interfere with its action or cause explosion. This withdrawing of the gases also prevents the gases from burning in the chamber or in close contact with the end of the tuyere, thus protecting the tuyere from injury from excessive heat and from becoming V stopped up with slag.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In combination with the tube A and the jacket B, the head C, formed with the chamber d, and the perforations c and e, substantially as and for the purposes set forth.
