team Patent No. 92,505, dated .my 13, 1869.
IMPROVEMENT IN BLAST-FURBNACES.
The Schedule referred to in these Letters Patent andv'making part of the same.
. To all whom it fnuty 'concer-nk.-
Be it known that I, GEORGE Arxius, of Sharon, in the county ofy Mercer, and State of Pennsylvania, have invented a new and improved Blast-Furnace;
'and I do hereby declare that the following is a full,
clear, and exact description thereof, which will enable others skilled-in the art to make and use the same, reference being had to the accompanying drawing,
`forming part ot' this specification, in which- `Figure l represents a, vertical central section of my improved blast-furnace.
Figure 2 i's a horizontal section of the' same, the' plane of section being indicated by the line :z: x, fig. 1. Similar letters of reference indicate corresponding parts.
This invention has for its object, to so construct a blast-furnace' that the waste gases, escaping from the ore or fuel, may be utilized7 and carried back to the ore, together with steam, hot air, or superheated steam. y The invention consists in the arrangement of gaspipes, which lead from the upper part of the furnace down to the tuyeres, through. which the blast is injected. lThrough these pipes, the escaping gases are conducted downward into the lower partof the furnace, where their heat and carbon may be utilized, while they pass up through the ore.
A,' in the drawing, represents the chamber of the furnace.
'B B are gas-pipes, leading from the upper part of the chamber to tnyeres l1, a, that enter the lower part ofthe same, the pipes B being'onthe outside of the furnace, as shown. I C C are pipes, leading from a steam-boiler, or fanapparatns, into the tuyeres, and/carrying steam, su-
perheated steam, or hot air, into the furnace.
' The pipes C may be carried up in the pipes B, and
then down again, to superheat the gases that pass through the pipes B. v
The gases that escape from t-he ore will, when the upper damper D is more or less closed, enter the pipes B, and thence through the tnyeres into the lower part of the furnace. They become mixed with the blast in the tuyeres, and, as they are forced into the furnace, a suction is produced in the pipes B, whereby further gases are drawn into the same fromabove. Y'
lhe ashes carried into the pipes B, by the gases, are collected in the'lower ends of said pipes, whichproject below the 'tuyeres, as shown.
Having' thus described my invent-ion,
What I claim as new, and desire to secure by Letters Patent, is-
A blast-furnace, provided with gas-pipes B, which lead from its upper part into ,tuyeres a, at the lower part of the furnace, and,' with the blast-pipes C, all arranged substantially as described, to utilize the gases that escape from the ore or fuel, as set forth.
Y GEORGE ATKINS.
