ORE-SEPARATOR.

. Speccation of Letters Patent.

Fatented J an. 27, 1914.

Application led July 29, 1913. Serial No. 781,788.

1/ 0 all 'whom it may concern Be itknown that we, FRANCIS J. HoBsoN, a citizen of the United States, and CHARLES E. BEYER, a subject of the King of Great Britain, both now residing at Nogales, in the county of Santa Cruz and State of Ari zona, have invented certain new and useful improvements in Ore-Separators, of which the 'following isa specification.

Our invention relates principally to that class of separating means utilized in metallurgical processes in which the materials to be separated are crushed With Water or mill solutions, and Where it is advisable or necessary to separate the coarser from the-finer particles, or Where it. is advisable tomake a number of classiications of `finely divided material for subsequent metallurgical operations such as concentration, amalgamation, lixiviation, cyanidizat-ion, etc., but it may be used for anyr purpose Where separation or classification of nely divided material is advisable or necessary. y

The object of our invention is to provide an improved construction of an efficient mechanical separator, which can be used, one

by' itself, or in series, Where more than two' classifications are necessary and in the sev eral parts are compactly arranged and which require a relatively small space and but a little loss in head from that ordinarily used for conveying gravimetrically finely divided material With Water and solution.

With other objects in view that will hereinafter appear', our invention consists of a mechanical separator of the rotary type, that embodies the peculiar construction and novel arrangement of the partshereinafter fully explained, specifically pointed out in 'the appended claims and illustrated in the accompanying drawings, in Whichz- Figure 1 1s a plan View, parts being broken away of our improved rotary sepy. arator. Fi 2 is a vertical longitudinal section thereof, taken on the line 2 2 on Fig. 1. Fig. 3 is' a detail cross section of the same taken on the line 3--8 on Fig. l. Fig. 4

is a detail'perspective view of one end of the drum, the adjustable bearing at that end of the drum and the brake devices that cooperate therewith. Fig. 5 is a transverse section of our separator and showing an alternative method of driving the separator. Fig. 6 is a detail view of one of the vane holding disks hereinafter described, With one vane attached. Fig-7 is a detail perspective view of one of the said vanes. Fig. 8 is a detail perspective view of the shiftable divider and its supporting casing or flanges. Fig. 9, is a diagrammatic view showing a plurality ot' separators in series.

In its practical arrangement, our rotary separator comprises a drum composed of end disks 1-1 and a series of transversely disposed vanes 2-Q, all .of like construction. The several vanes, in the preferred construction are of flexible sheet iron and may be curved or straight, they being shown curved. Each end disk has a series of grooves 3 on the inner face which are curved to the cross sectional shape ot the blades or venes, and these intting up the parts are slid edgewise into the said grooves. The drum also includes a plain cast hollow cylinder 4, the ends 5 of which have apertures or bearings 6 for a central shaft 7 and the said cylinder ends 5 are iixedly attached to the shaft 7 to rotate therewith. To the cylinder ends 5 are screwed the end disks 1 that carry the vanes 2, as clearly shown in Fig. 3 of the drawing.

S designates a trough or cast iron box that is open at the top at one end, and at -the bottom, it having inside flanges 9 at the bottom (see Figs. 5 and 8) the purpose of which will presently appear. For cooperating with the drum and to provide, as it were, a casing in which the upper end of the drum rotates, we provide an ironl cover 10 formed at the top With a rectangular hopper or feed box 11. Cover 10 is fitted to the upper horizontal lianges 12 of the trough 8, it having lugs 13, that receive the clamp bolts 14 that pass through elongated slots 15 in the said anges 12, to permit of tral shaft 7 and they are adjustably secured on the trough flanges 12 by the bolts 18 that pass through the slots 17 in .the said flange 12.

The entire apparatus can be supported on timbers 19 bolted to iianges 20-20 on the trough 8, as shown in Figrl, or in any other suitable and convenient manner.

21 designates what we term the divider, and the same consists `of a bottom member vin the nature of' a plain angular casting which rests of its own weight on the inside anges 9 of the trough (see Fig. 8).` The divider, by reason of its being loosely supported so it may be moved forward or backward, can be readily set to adjust the discharge of the machine.

In the preferred construction shown, the drum is arranged for being driven by power generated by the material and water that passes through the separating machine. In practice, We have found that more thansuiiicient. power is so generated that it is necessary to usey a brake or retarding means. We have shown a brake composed of a friction block 22, having a concaved seat 23 for engaging the langedcollar 24 keyed on the extended end of the shaft 7. Block 22 is controlled by a lever 25 pivotally mounted on a bracket 26 adjustably connected to the trough flange 12; said'le'ver seat-s in a groove 27 on the top of the block 22 and is held down by the adjustable Weight 28, all clearly shown in Fig. at of the drawings. In Fig. 5 we have shown a pulley 29 on the'shaft 7, which may be driven by a belt, worm gear or any other practical power transmission means.

In operation, the'crushed o1' finely divided material with water or solution is delivered into the hopper 11 from where it drops into the several pockets or spaces formed between the vanes 2 which in practice are caused to revolve in; the direction indicated by the arrow 30 in Fig. 2). When operating for the' separation of ore, sands and slimes, the slimes are held in suspension in the water or solution, until the vanes arriving at a position low enough in the path of rotation, at which time, most of the solution is discharged or Hows olf onto the forward side Y of the divider 21, and with it the slimes,

which are in suspension. After passing the apex of the divider the heavier articles, the sands, and the remainder of e water or solution, gravitate to the other side of the sand divider 21. At this point it should be mentioned that at the inner or back each 'the sands over the inner cylinder.

vane has small apertures 32 for the admission of air for overcoming a suction forming which would have a `tendency to carrlrly e amount of s limes or tine material separated is adjusted by the setting of the divider 21, changing the position of the drum and its cover in relation to the trough and the divider 21, and by adjusting the speed with .which the drum revolves.

.eisl before stated, whenmore than two classes of material are necessary or advisable, two (or more) machines can be run in series, (see for example Fig. 9) and the desired number of separations be thereby made, the feed for the second or series separators .being taken from either discharge of the preceding separator, governed by the character of the material used.

From the foregoing taken in connection with the drawings, the complete construction, the operation andthe advantages of our invention will be readily apparent to those skilled in the art to which our invention relates.

What we claim is:

1. A rotary separator composed of end disks, a hub and a series of transverse vanes that divide the drum into a series of radial pockets, the vanes having apertures for the circulation of air in the hub ends of the pockets, and means for dividing the material discharged from the separator.
