srncrrrcnrron forming part o'f Letters Patent No. 681,271, dated August 27, 1901.

Appncttion flied July 11, 1to0.

Lof theUnited States, residing at Ouray, in the `county ofOuray and State of Colorado, have invented certain new and useful Improve-l scription of the invention, such as will enable `others skilledin the art to which it appertains s IS to make and use thesame, reference being had l, `mentsin Ore-Concentrators; and I do declare the following to be a full, clear, and exact detothe accompanying drawings, and to the leta part of this specification.

"ters of reference marked thereon, which form This invention Vrelates to improvements in l `ore-,concentrators of that class wherein a rotary member fashioned to constitute a receptacle for the material to be treated is ein-l isc ;ployed,y whereby centrifugal force may be utilized to a large extent in effecting the sepag ration of themetals from the ores.' Briefly g stated,the invention may be classed as a cen- `trifugal ore-separator. Thepresent invention is designed more par- 1 ticularly as an improvement on the appa-f ratus shown and described in United States Letters `Patent No. 648,088, dated April 24:, i 1900, issued toV myself.` While in generali i principles `the machine is related to that type of and is an improvement on the said pat-4 ented machine, yet the construction in manyl `particularsdifters materially therefrom and embodies features whi'chconstitute material improvements, resulting in adding great stability, easeof operation, more eifective separation, andpermitting of the control of the material, Aso that the separation may. be governed readily, according to the character and state of the material being treated The objects of the invention are to provide a suitable supporting-frame for the separator, a clear-water-feeding device which will .have an independent source, means for adjusting the delivery and collecting tubes so i that their receiving-openings may be varied tosuit the character-of the material being treated, amechanism for effecting the adjustment which can be operated during the operation of the machine, improved collectingpans, and in general features and constructions presently to be described.

In the accompanying drawings I have shown Serin No. 23,214. (No man.)

` an embodiment of the invention, but desire it understood that various changes and modications can be made without departing from the nature and principle of the invention.

Figure l is a longitudinal vertical section showing parts in elevation. Fig. 2 is a side elevation. Fig. 3 is a section on the line a: ee of Fig. 1. Fig. 4 is a section on the line y y of Fig. 1. Fig. 5 is a section on the linee ,eef 6o Fig. l. Fig. 6 isa detail planof the rotary sleeve, its link connections, and Atube-adjusting means. Figs. 7 and 7a are detail sections ,l of the respective tube-adjusting and clamping mechanisms, and Fig. 8 is a detail per- 65 spective view of one of the tubes.

A designates a base which is conveniently constructed of four radial arms having a central hub or step-box A. The base A carries at theend of its arms flanges a, and each 7o arm is perforated to receive an anchor-bolt a'. Secured to the flanges a are uprights B,

" which are obliquely arranged at a point a distance above their lower ends and extend up- `ward and inward, terminating in vertical sections b, which are boltedto yokes B B2, as shown in Fig. tt. i O designates the separator, which is conveniently of conical formation, having the `bottom C formed with its outer portion in- 8o clinin-g downward and thence directly outi ward, as at c, forming thereby an annular .collecting-channel, the side walls of which are inclined, as shown inFig. 1. On the outside of the separator near its upper end is formed 85 an integral pulley or belting surface C2, forming in addition a shoulder at the top, from the inner portion of which extends the vertical cylindrical bearin g c2, embraced by the yokes B and B2.

is enlarged s and formed into a hopper O3, the upper edges c3 of which project inward a short distance and constitute lips to prevent the material Into this 95 `from splashing out over the edge. hopper the material to be treated will presently be described.

D designates the supporting shaft or spindle, passing through the bottom C and supis fed, as

porting the separator by any suitable means 10o conveniently, such as a jam-nut d, located below the bottom and threaded on the shaft The upper end of the separator 9o above the cylindrical portion c2 or spindle. The lower end of the spindle carries a detachable bearing D', having sloping sides and a depending center. This bearing is clamped to the spindle by having an up- Wardly-extending marginal flange engaging a groove in the end of the spindle, the flange being engaged by the clamping-band d, the tightening of which firmly presses and holds the bearing to the spindle. Other securing means for the bearing may be employed. In the step box or hub A/ is placed a steel bearing-block E, having a ball-raceway formed in its upper face and between which and the bearing D are a series of balls e, thereby forming a ball-bearing for the spindle for the separator'. The upper end of the spindle has cast integral therewith a flange or platform D2, having inclined upper faces. Below the platform are a series of radial fins d2, while above the platform are a series of obliquelyarranged wings cl3, extending to the sides of the casing, as shown in my former patent, hereinbefore referred to. The extreme upper end of the spindle is reduced in size, tapered, and formed hollow, as at d4, the same terminating at a point below the upper end of the interior of the separator. From the -hollow or tubular portion of the spindle extend channels d5 outwardly to the sides of the casing, where they communicate with pipes or channels F, formed in the sides of the separator and extending downward to a point near the bottom thereof. To securely unite the spindle with the walls of the separator, screw-bolts c4 are employed, passing through the walls of the separator into the platform formed on the spindle. These bolts act in conjunction with the nut d, and by the in- -clination of the separator and the outer edges of the platform the wings and tins serve as a wedge, firmly binding or impinging against the walls of the separator. With this construction a very rigid connection is formed.

G designates a water-s-upply tube entering centrally through the upper end of the separator and having threaded engagement with the upper end of the spindle. centered and held in place by any suitable means, conveniently by set-bolts g, passing through the hopper portion of the separator at different points and radially.

g designates the funnel or receiver for the supply-tube G, the same being provided with an annularly-extending ring or flange g2 to prevent the contents of the funnel or receiver from being thrown out centrifugally during.

the operation.

By the construction thus far described it will be observed that the machine is provided with means whereby a fresh and independent supply of water can be supplied to the interior of the separator and delivered at the proper points, also that the machine is rigidly supported by the independent frame and that the .driving-pulley is made a part of the separator. However, other means fordriving the separator may be employed.

This tube is Located in the outer walls of the separator at or near the lower edge are the collecting and discharge tubes H, their ends being projected a distance above the bottom of the separator. These tubes have longitudinal apertures h therein, and the tubes are seated in suitable cavities or seinicircular grooves formed in the sides of the separator. The upper ends of the tubes are opened and communicate with the lower ends of the water-supply tubes F, so that the discharge of water is directly into the tubes H. To secure the tubes Hin their properadj usted positions,a conicalshaped split nipple J is employed, the same fitting in a screw-threaded aperture formed in the base O. Through this nipple the tubes H pass and are clamped in position by a nut H', fashioned to engage the outer threaded surface of the split nipple .I and force the latter closely against the tube. The nut H' is formed with an annular flange h at its outer end for purposes presently to be described.

K designates the discharge-tubes for the lighter materials. These tubes are secured by suitable nuts and split nipples, as heretofore described, passing through the bottom C at points inward or between the center and the walls of the separator. The tubes K extend a considerable distance downward, as shown in Fig. 1.

In such machines it is usually found necessary to vary the size ofthe receiving-openings of the concentrator or discharge-tubes H, and itis desirable to effect this adjustment orvariation without stopping the machine. To yprovide for such, I have inserted in the tubes H the interior or supplemental tubes L,which extend conveniently the entire length of the tubes H and project a considerable distance below the machine.- These tubes L have registering receivingopenings Z of a size corresponding with the openings h in the tubes H, so that as the tubes L are set to have the openings register the machine .will be set at its full capacity, but by turning the tubes L the size of the openings will be correspondingly diminished. To effect this turning duringthe operation of the machine, I secure to the tubes a split nipple M, which embraces the projecting end of the tube L and is clamped thereon by the set-nut fm, fitting over the nipple. The end of the nipple M has a circular flange m', from which extends a semicircular flange fm2, from the edge of which extends inwardly a fiange m3, thereby forming a semicircular channel or receivinggroove, which when properly arranged engages the flange 7i of the nipple H', and thus serving as a means for retaining the tube L in position, but permitting its rotation, the se micircular formation of the retainin g-ilan ge being for the purpose of readily applying the retainer to the nipple H and permitting its removal. From the iiange m' of the nipple M extends an arm N, to the outer end of which is attached a link O, which extends inwardly tangentially or at an angle to and IOG IIO

-IZO

\ is connected loosely with a collar P, sleeved s on the lower end of the spindle D. `This collar has an inwardly-extending pin p,which takes into an oblique channel formed in the spindle, while PIO ` opposite sides, as shown. The yoke S is pivoted to a stud T on the base A and has an upwardly-extending arm S', 'forming a bells. crank/to which the actuating-bar U is pivoted, the latter extending outward to and passing through a suitable slot in one of the g standardsor frames B, the end being threaded and having receiving-nuts u on opposite sides of the bar B,so that its position may be "adj usted. By this means; it will be seen that by drawing the bar U outward it will raise the inner end of the yoke'S, thus elevating i the ring R, which in turn elevates the collar iP, carrying the same upward on the spindle l" YD, and by virtue of the inclined slot P' and `the pin entering therein the collar P will be turned slightly, thus drawing in on the links IO, and thereby turning the clamping-nipple M slightly, according to the degree of movement, and rotating the inner tubes L, thus carrying their openings transverselyand de- `creasing the inlet-openings to the tubes. By this means the variation of the discharge- `iopening may be easily adjusted during the ,operation of the machine. The tubes K Vand L discharge into receiving-pans V and V', i each of which are inclined gradually and are arranged in a circle. At the lower end of these receiving-pans are any suitable dis` charge outlets or tubes, (not shown through whichthe material is drawn and conveyed to any suitable place." Any desirable type of `valve or gate may be employed for this pur- 1 pose. It frequently occurs that the position of the receiving-pans relative to the end of the` discharge-tubes needs to be adjusted. Toelfect this,l c onvenientlysupport the pans by having suitable lugs c formed thereon, Qwhichfrest on blocks 1:2, held in position by bolts and nuts passing through vertical slots i v3, formed in the supports B.

Ihave described one discharge-tube, but4 it is to be understood thatfour will ordinarily be employed, arranged an equidistance apart; but any desirable number may be employed.

` In operation the material is deposited in `the hopper C3 and descends into the separator, ,at which point it is caught bythe wings d3 iand by the centrifugal force is carried out- `ward, the material discharged at the outer edges of the table D2, which table is cut away, I :leaving the passages `d6 between its edge and spindle, the collar being susceptible of in` same and pivotally connected therewith on the sides of the casing, asshown in Fig. 5. The material being forced to thesidesof the casing escapes into the separator below the table, and by the rapid rotation of the separator the heavier particles hug the sides, and. owing to the inclination of the sides of the separator, the discharges being at or near the angle of juncture of the bottom and sides, the natural tendency of the particles is to sink downward; but owing to the increasing size and consequent peripheral speed (or belt-motion) kof the casing the particles will not move on a meridian line, but constantly lag back from such meridian line with each successive point of movement downward, and thus pass spicasing, pai-taking somewhat of this increasing motion by reason ofthe friction` on the sides, the result of such action being that the heavier spective specific gravities hugging the sides of the casing and made to passtransversely across the openings in the discharge-tubes H, through which such portion as may be desired is made to pass. As theyenter the disbythe incoming water received from the supply-pipe G and through the pipes F, the water serving also to keep the discharge-tubes clear. Such particles and material as are not permitted to be discharged through the slot in the discharge-tube H contiuuein the downward direction and are carried into the discharge-tubes K. The inclination of the bottom C serves to force all the material below the slot in the tube4 H to be discharged, `per mitting no inert or neutral matter to remain, and thus causes a regular continiioualiow and movement of the particlesand material (pulp) in accordance with the capacity of the machine or amount fed into it. rious tubes "the material is deposited into the receiving-pans V V.

The adjustment of the tubes having been described, their operation it is deemed `un,-

Vthat the openings c' and h in the tubes may be set to register in such length asidesired less than the full capacity by inserting thetube L farther into the tube H, thus reducing the length ofthe slot. The size of such opening may then be diminished, as before described. Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is s 1.
