IMPROVEMENT IN SEPARATORS FOR IRON AND OTHER ORES. A

Specification forming part of Letters Patent No. 139.782, dated June 10, 1873; application filed November 14, 1872.

To all whom it 'ma-y concern:

Be it known that I, ALEXANDER GooD- HART, of Newville, in the county of Cumberland and State of Pennsylvania, have invented an Iron-Ore Separator, of which the following is a specication:

The invention consists in separating dirt from ore by drying them both together and then detaching the dirt by concussion. It also consists in a new mode of combining instrumentalities for drying the ore and dirt 'and for detaching the. latter.

The drawing represents a side elevation.

A in the drawing represents an oven, arranged for drying the ore as it is exhumed, and provided with a mouth or feed-hole, a. B is ayheavy sheet-iron pan, passing through the middle of oven and receiving the ore Vthrough hole a. C is the hopper into which the desired ore and dirt are discharged from pan B, which has the sliding gates b that regulate the quantity and time of discharge. D

lis the lire-place, and E the smoke-stack. F

represents a series of posts which form a frame, preferably about three feet square and four feet high, While B is the cyliudersbaft. H Hl are cast-iron heads, about twenty inches in diameter, and provided with the four flanges h on each one. I I are circular cribs, which 'may be made of cast-iron grat-es, of iron rods, or of heavy wire screens, and K K K are circular wooden rings or fellies, to which said cribs are attached. L is a shaking-screen, and M Ml are the frame and xtures for working it. N is a sheet-iron cylinder placed outside of the Wooden rims or fellies, for the purpose of stoppingall dirt that passes` through cribs andconveyiug it to the shakingthe ore passes to the shaking-screen L, 'which i eliminates the dirt. 1t will thus be perceived that the ore is .cleaned completely without` l n washing. y

Having thus described my invention. what I claim as new, and desire to secure by Letters Patent, is

1. A supply 'eedhopper, (l, rotary `heads H H', cribs l l and screen L,colnbined and arranged as and for the 'purpose described.

2. The combination.,` with feedhopper, of oven having pan B discharging thereinto, as and for the purpose described.

i 3. The described method of cleaning ore by drying it as it comes from the earth and then i separating the soil therefrom, thereby dispensing altogether with the washing operation. i
