Description

R. P. WILSON. Apparatus for D'esulphurizing Ores. No. 226,692. Patented April 20,1880.

RILEY P. WILSON, OF NEW YORK, N. Y.
APPARATUS FOR DESULPHURIZING ORES.
SPECIFIGATION forming part of Letters Patent No. 226,692, dated April 20, 1880,
Application filed June 12, 1879.
To all whom it may concern Be it known that I, RILEY P. WILsoN, ofv
which is accomplished by graduated flues growing narrower from center outward.
It is found by actual operation where the lines are of even width and size from center outward that the heat drives the moisture centrally and has a tendency to cake up the ore, so that a perfect desulphurization cannot be effected; but where the fines are wider at the center this caking does not take place, as the ore being roasted is more gradually heated. This arrangement and construction of the lines, although apparently very simple, still in operation are of great value.
In the accompanying drawings, Figure 1 represents a sectional view of the entire apparatus.
A indicates the hopper; B, the feeder; F, the oven; E, the feed-pipe; G G, hollow arms or pipes for stirring the ore, carrying it at the same time gradually outward and distributing the air into the ore through vertical teeth at the practical point and time.
L is the hollow shaft by which the arms G G are revolved, and through which the air is conducted.
J J J, 850., are flues gradually narrowing from center outward, through which the heat and draft are conducted from the furnaces P P P, as seen in Fig. II, these flues being immediately beiieath the floor of the oven F.
h is a mufiier, arch, or cover of the oven F. E is the inlet of the ore, passing into muffler h. l) is the shaft driving feeder B. M is shaft driving shaft L. N is ore-outlet after being desulphurized.
The operation is as follows: The crushed ore is put into hopper A and conveyed gradually by feeder B into oven F, and then is conveyed gradually from center to circumference, being thoroughly and rapidly roasted in passing. The ore then passes out through spout N into a receiver to be amalgamated or otherwise treated.
I am aware that there are other muffle-furnacesconstructed so that the heat is distributed in an even manner. .I disclaim such apparatus, and-claim only graduated fines in combination with a muffled furnace.
VVha-t I claim, and desire to secure by Letters Patent, is-
The graduated flues J J, in combination with the muffle-oven F, for the purposes set forth.
