SEPARATOR FOR SIZING ORE, 80C.

SPECIFICATION forming part of Letters Patent No. 325,557, dated September 1, 1335.

Application filed February 2-1, 1855. (No model.)

To aZZ whom it may concern:

' Be it known that I, WILLIAM A. Mines, of Copake Iron Vorks, in the county of Columbia and State of New York, have invented an Improvement in Separators for Sizing Ore and other Mineral Substances, of which the following is a specification.

This inventionis for the separation of ore and other mineral substances according to the size of the pieces, and it is especially useful after the ore has been washed in a revolving apparatus-such, for instance, as that shown in Letters Patent No. 108,962, granted Novemher 8, 1870, to H. Bradford. \Vhere my in1- provemcnt is applied to such an ore-washer it will form a cylindrical extension at the delivery end, and be revolved with and by such washer. It is, however, to be understood that I do not limit myself in this particular.

I make use of metal rings placed side by side to form a cylindrical range or ranges, and supported so that openings are left between one ring and the next of the desired width. These rings are wider upon their inner surfaces than upon their outer edges, and such rings are supported and kept at the proper distances apart bylongitudinal bars passing through lugs that project radially from the exterior portions of the rings. A cylinder formed of these rings is supported upon a shaft or bearing-wheelasuch as in the aforesaid patent, so as to be revolved, and the material to be screened passes in along the interior, and that which is suffioiently small to escape between the rings passes to one receptacle, while that which is retained within the cylinder passes to another receptacle, thus separating or sizing the ore or other mineral substances. \Vhere several different sizes are required in the separation, I place one cylinder of rings outside of another, the outer rings being wider, so as to lessen the spaces between one ring and the next.

In the drawings, Figure 1 is a longitudinal section of the separator having three ranges of ring-shaped bars, and Fig. 2 is a cross-section of the same at the lines at m, Fig. 1.

Each ring of this separator is trapezoidal in its sectional form, the broadest face being inwardly, so that the spaces between the rings diverge; hence material that passes through between one ring and the next will fall away and not become wedged. Each ring is provided with two, three, or more projections, a, standing radially from the outer edges, and these projections are perforated for the passage of tie-rods b, and tubular washers c are intro the proper distances apart.

A cylinder is made by placing side by side any desired number of these rings and connecting them together, as aforesaid; and to render this cylinder stronger, I prefer to cast the projections a with ribsiat their outer ends, and to make use of grooved bars 7;, extending longitudinally outside of the cylinder and receiving into their grooved surfaces the said ribs 13 1'. These bars are bolted to and supported by the flanged ringsllat their ends, forming heads to the cylinder. The ring Z at one end is made with arms extending to ahub, a, through which passes the shaft m, and this shaft is sustained in suitable bearings upon a frame and revolved by competent power." There are also arms 1) at suitable distances apart, extending from the inner faces of the separator-rings to a hub or hubs, q, around the shaft m, near the middle and other end thereof, so that this cylinder of separator-rings is supported and rotated by the shaft m,which will usually be at an inclination sufficient to cause the material that is being separated to run through the cylinder of rings; but the shaft m may be horizontal, as shown in the drawings, Fig. 1, in which case I make the arms 1) as inclines or diagonal plates similar to the section of a screw, the same acting as the cylinder of rings revolve to continually press the material forward toward the delivery end.

h ere this separator is intended for but one size of material, there will be but one cylinder of rings, the smaller pieces passing through between the rings and being received into a suitable receptacle.

IVhere the separator is intended for use with two or more sizes of material there willbe two or more ranges of concentric rings, forming separator-cylinders. I have shown three such ranges of rings, marked, respectively, R S T. The ring-shaped bars R are narrower than the bars S, so that the spaces between the bars R are. wider than those between the bars S. In like manner the bars T are wider than the bars S, and the spaces between them narrower. In consequence of this construction the mineral substances passing through the wider openings between the bars R will be screened by the bars S, the larger pieces being retained upon the surfaces of said bars S, while the smaller pieces pass through between them; and the bars T still further separate the mineral substances, the finest material passing through between said bars T. In this way T am able to obtain four different sizes.

In the delivery of the material from the re spective cylinders of circular bars suitable chutes may be made use of. I however prefer to make the cylinder R the longest and the cylinder S shorter, and the cylinder T the shortest, in order that the material passing off the 1 end of the cylinder B may be received into a which is broadest on the inner face and provided with external projections, bolts passing through such projections, and tubular washers around the bolts and between the projections, substantially as set forth.

2. The combination, in a separator formineral substances, of a range of rings, each of which is broadest on the inner face and provided with external projections, bolts passing through such projections, tubular washers surrounding the bolts, the supporting-bars k, and end heads connecting such bars k, substantially as set forth.

3. The combination, in a separator for mineral substances, of ranges of rings forming separatorcylinders, the inner rings being narrower than the next range of rings, projections connecting one ring with the next outer ring, bolts passing through the projections, and tubular washers surrounding the bolts and maintaining the proper distances between the respective rings, substantially as set forth.

4-. The combination, in a separator, of ranges of rings forming separator-cylinders, the inner rings being narrower than the next range of rings, projections connecting one ring with the next outside of it, connecting-bolts, and tubular washers, diagonal arms 19, hubs q, and shaft m, substantially as specified, whereby the diagonal arms cause the material to be moved along within the separator as it is revolved, substantially as set forth.

Signed by me this 9th day of February, A. D. 1885.

WILLIAM A. MILES.
