Steam, or Gas and Air YBI ast-Pipe for Furnaces STATES FFI@ GEORGE H. GOODSELL, OF VLEEGHBURG, PENNSYLVANIA.

y IMPROVEMENT IN STEAM OR4 GAS AND AIR BLAST PIPES FOR FURNACES.

Specification forming part of Letters Patent No. 165,56 l, dated July 13, 1875; application filed May 17, 1875.

To all whom it may concern Be it known that I, GEoRGE H. GooDsELL, of Leechburg, in the county of Armstrong and State of Pennsylvania, have invented a new and useful Improvement in Combined Gas or Steam and Air Blasts for Furnaces for nietallurgie and other purposes; and I do hereby declare that the following is a full, clear, and exact description oi' the same, reference being had to the accompanying' drawing, forming part of this specitication.

This invention is applicable to blastiurnaces of different kinds, includingfurnaces for the reduction ot ore, iron-refineries, puddlingvi'urnaces, and, in fact, any furnaces in which a blast is used and an intense heat is required, as in the manufacture ot' iron, for which purpose the invention will here be described as applied to.

rlhe invention consists in the combination,

- with the air-blast pipe, of one or more steam 0r gas pipes arranged to conduct a current or currents of steam or gas, or both, in front of the air-blast as it issues from its pipe, whereby a more intense beat-is produced, also a more perfect combination eii'ected andthe product ofthe iurnace improved.

Figure l is a side view ot' a furuacetuyere, with air-blast pipe and steam or gas pipe combined, Fig.2, a longitudinal vertical section of the same, and Fig. 3 ahorizontal section thereof.

A is the tuyere, which may be of the ordinary construction, the improvement being capable of application to tuyeres now 1u use Without altering the saine. B is the air-blast pipe inserted in the tuyere. C C are tubes arranged to enter the tuyere on either side of the air-blast pipe, and with their delivery ends made to project in front of said blrs! pipe Within the tuyere. These tubes serve.

to conduct steam or gas, or both, in advance of the air-blast, and so that the steam or gas is caused to mingle with the air of the blast at the most efficient point to bring them and the air in contact with the iire. Said tubes U (l may be connected outside of the tuyere with a valve, D, common to both, for regulating the supplyl ot' steam or gas, or for shutting' ofi' the same when the air-blast alone is required to be used; or the steam or gas may be used alone, or in combination with the air, as circumstances require. The valve D is connected at b with the gas-supply pipe, or, by removing the latter, with a steam-supply pipe ofthe same size, by means ofa union coupling. Goal or any other suitable gas may be used. The tubes C O, instead of being arranged outside of the blast-pipe B, as represented, may pass through the interior of said pipe. 'Ihe gas or steam being conducted through or Vinside of the tuyere to a point in front of the blastpipe nearest to the furnace, the force ot' the blast will drive the steam or gas to its proper point oi' contact with the fire. By this mode ot introducing the steam or gas, or both, in common with the air of the blast, a more intense heat may be obtained, and more peri'ect combustion, also a much superior quality of iron be produced.

I claim- The combination of the tuyere A, air-blast pipe B, arranged therein, and -steam-tubes c c on the exterior of', and projecting in front ot', the air-blast pipes, substantially as shown and described.
