SMELTlNG-FURNACE.
SPECIFICATION fcrming part of'Letters Patent No. 286,777, dated October 16, 1883.
, Application filed June 30,1883. (N model.)
To all whom it may concern:
Be'it known that I, EDWARD OARTWRIGHT, a citizen of the United States, residing at Wilber, in the county of Saline and State of Nebraska, have invented certain new and useful Improvements in Smelting-Furnaces; and I do declare the following to be a full, clear, and
naces for gold and silver; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described,
and particularly pointed out in the claims appended.
The expense attending erection of blast-furnaces for smelting gold and silver ores is so great that it is not practical to build them at all mines, owing, in some instances, to the refractory and low-grade ores mined, and the low grade that will not pay sufficiently, in other instances, to transport them to furnaces already erected at a distance. Besides, large quantities of the ores in the mining regions are refractory and cannot be treated at all in the blast-furnaces. In order to surmount these and other difliculties, I have constructed a furnace for smelting the low-grade, refractory, and other ores without a blast and from material nearly all of which may be found at any mine, whereby but little cost of transportation of material is incurred, and whereby I am enabled to erect a smelting -furnace at any mine.
To enable others skilled in the art to which my invention appertains, I will now, describe it, referring to the accompanying drawings, and the letters of reference marked thereon.
a designates an elongated arched furnace, which connects at its narrower end with a second furnace, b, which has vertical front and end walls and a convex or arched top and back, as shown in the drawings. f designates the the lower corner of the extension;
' fire-box for the furnace a;f, the grate for the same; the ash-pit, and f the door to the fire-box. The top and bottom of the furnace a curve downward from a point at about a to the point of junction of the furnaces a and b, and the furnace at narrows gradually in its ap proach to the furnace b, as shown in the drawings. v v
c is the door which closes the openingleading to the embed a, which lies between the point a and the fire-box f. The ore or quartz is to be placed on thisore-bed c to be melted. I preferably place ribs (0 a of the outline shown in dotted lines in Figs. 1 and 2, on the bottom of the furnace a, at its sides, tov retard the flow of the melted ore or quartz and pre vent it from entering the furnace b too rapidly. The reflector-furnace b is provided with a firebox, I), through the door 1* of which the charcoal or other fuel is fed. 8 is the exit from this furnace to the smoke-stack s, which is provided with a hinged cover having an arm and a rod, by which the cover may be manipulated to regulate the draft. The base of the furnace 72 extends in front of the front wall of said furnace b, and this projection is open at the top, as shown. The front wall, W, of this extension is termed the dam. The lowest point of the bottom of the extension is at the front left hand corner, and the lowest point of the top of the dam is at the front and gases pass at the flue 3 into the smokestack. After the metal passes into the reflector-furnace b, it there liquefies and separates. The metal, sinking to the floor, runs to The cinder or slag, being lighter, floats on the top and passes off atthe point a at the top of the dam.
By this construction I am enabled to smelt I usually coat the interior walls of IOC quartz, low-grade and refractory ores of all kinds, and the expense attending the erection of such a furnace is such that it may be put up and made to pay at all mines, no blast being necessary, the draft and reflection doingthe' dam b", substantially as specified.
2. The combination, with the reflector-furnace b, having the bottom and top concave interiorly, and the front base-extension with depression m, and the low portion '22 in the top of "thedai'n if, of the arched elongated furnace a,
narrowing gradually from the fire-box f to the point of connection with the refiector-furnace I), substantially as specified.
In testimony whereof 1 Mb); my signature in presence of two witnesses.
