Patented Jan. 11, 1910,

Application filed September 1, 1909. Serial No. 515,722.

To all whom it may concern;

Be it known that I, LABAN ELLswoR'rH JONES, a citizen of the United States, residing at Anaconda, in the county of Deerlod'ge and State of Montana, have invented certain new and useful Improvements in Centrifugal Separatore, of which the following is a` full, clear, and exact description, referdrawing? forming a part hereof.

y invention has relation to improve-y ments 41x1-centrifugal ore separators; and 1tv consists in the novel details of construction Vmore fully set forth in the specification' and pointed out in the claims.v

In the drawings, Figure 1 is a middle vertical 'section on the line 1-1 of Fig. 2 of the separator; Fig. 2 is a horizontal section on the line 2-2 of Fig. 1 with parts broken away; Fig. 3 is an elevation of the separator with parts broken away; and Fig. 4t is an elevation at right angles to Fig. 3, with parts broken away.

The. present apparatus while primarily designed for the treatment of ore pulp with a view of separating the concentrates omthe tailings as for example, in concentrating finely pulverized ore,sl1mes and the like, may be utilized for treating any kind of material mixed with water with a view of separating thereof which is as follows r-Referring to the drawings, S, represents a central vertical drive-shaft to which rotation may be imparted in any suitable mechanical manner, that here shown being a pulley P from which leads a drive-belt. B to any source of power (not shown). vCarried by the shaft is ra spider 1 to the arms of which is secured is to construct an the shape as shown, the said-container hav- A ing. peripheral converging or'sloping walls forming an outer circ ar V-shaped groove or pocket z,l for the heavier particles or concent-rates which separate out under the action of the centrifugal 'force with the .rotation of the shaft S and the container 2 coupled thereto. Loosely mounted on, and freely rotatable about the' shaft S is a quill or sleeve 3, to which is secured the upper end 'of a cone 4, the lower portion of the cone being rigidly connected to the, sleeve by the the containeror centrifuge 2 of substantially u arms of a spider 5, the cone being free to rotate in the container 2, the inner inclined wall`of the container projecting upward to a. point adjacent to the spider 5. Disposed along the upper surface of the cone' L1 Iwithin thecontainer or centrifuge 2 (and preferably riveted to the cone), are a series (two shown herein) of inclined plow-share shaped blades or wings 6 which are free to revolve within the container, fitting the latter neatlyv at all points except at the pocket z., said pocket being reserved for the-.projection and y accumulation ofthe concentrates as presently to be seen. To the upper edges of the blades is anchored (preferably riveted) the revolving top 7 said top being provided with a central charging flanged opening :0'

encompassing the shaft S and'sleeve 3, and with marginal openings 0 for the escape of the tailings as presently to be seen.

On the back ofeach blade 6 is secured, a

curved concentrate-discharge pipe 8, the y outer end of which opens into the pocketvh,

the inner open end of the pipe discharging l the material through the wall of the cone/5,4 at a point adjacent to the drive-shaft,'tlie material being caught in 4a receptacle 1R whence ittmay be conducted to any 'convenient point for subsequent treatment. The tailings discharged through the openings o and which run overA the outer walls 'of the container,'are caught in a' suitable troughT whence they-may be conducted to any suit- 3 is idingly feathere (though free to revolve with" the sleeve)V the movable clutch member 9 controlled by.A a suitable lever 10,

said member 9 'coperating with. thel relatively fixed clutch section or .member 9 able point.` To'the up er end of the sleeve keyed or otherwise secured to the shaft S.

0n the opposite or under side ofthe clutchsectiou-Q isaii arresting support or bearing ll which the member f) may engage when disengaged trom its complementary sectionvfl The operation of the separator is substantially as tollows2-t`he operator sets the rotating, thel liquid soon attaining its full' rcvolgging sneed. when the .wings and their sleeve are`-ciiiis coupled or clutched ,'to the shaft, the parts S, l, 2, 3,4, 5, 6, 7 and S (and the pulp) revolve as a unit about the axisot the shaft, the centrifugal torce undern the circumstances project-ing the heavier and',

coarser particles of the 'pulp outwardly into the pocket 7i; the finer particles oi tailings distributing themselves interiorlyto the circle defining the inner limits of the pocket. The depth (or width) of this pocket obviously, may be varied by varying the radial dimensions of the blades, the available pocket proper being the space between' the converging walls ot' the container measured from the vertex of the angle between said walls to the adjacent edge ofthe blade 6. In order to remove the concentrates thus sep arated under the action ot theJ centrifugal force, the operator disengages the clutch members, the member 9 settling down on the bearing 1l, such ,disengagement uneoupling the sleeve 3, cone 1L and blades 6 with their pipes 8 from the shaft S. The shaft S and container Q of course, continue at their original speed of rotation, but the blades (i and pipes 8 necessarily slow down. By reason ot this diifcrential in the speeds between the container and blades, the material concentrated in the pocket 7L, and whose inertia tends to carry it around at the speed ac.- quired bythe container, is constrained (since it can not pass the blades) to enter the pipes 8 Vthrough the ends -which open into the pocket, after which it flows through said pipes toward the cone t, being` discharged lfrom the pipes through the wall of the cone into the receptacle R. The momentum acquired by the lighter portions of the liquid carries the liquid out of the discharge opening o', the liquid being in a measure directed toward said openings by the formation of the blades. Once this liquid or tailings has pissed out of the openings 0 from which it is expelled by centrifugal force, it is collected in the trough -T whence it may be conducted to any suitable point. Thus the two eeefiafi t portions are separated and the machine is ready for another charge.r t l v'lfhe time to'r chargingl and discharging a tanl; or container of several hundred gallons oi? pulp need noty be'inore" than a tcw scconds; and the enti-re operation though intermittent, Amay be readily made automaticby scoop up, collect or gather the concentrates accumulated in. the'pocliet it, during; the periods rof diliorc-ntia'l.' speedsI between the coni 'tainer and -tllife blades, the cuiwa'ture'ot' the couijs e,`theV direction',of,l rotation Yofthe. in'a .chine Ais n'e'eessarilly"opposite tothe direction da cont-finer and :blades obviously th-c -outfrxeiids oi' the' present invent/ion it is ot' course immaterial shown here is but one methody of accomplishrelatively slower -speedintheblades, or`the bladesmight even be sta.tioi1alry for the time being', a conditioirivhich.- would. arise when would not be'outside of .the spii'it oi' the present invention were the 'differential to result from a rotation of the blades in 'one direction while the container was rotating` in an opposite direction, the diii'erential being a difference in speed between two bodies rotating positively, or one positively and the other negatively. In any oi' these eases the outer ends of the pipes 8 would scoop up the concentrates during their traverse of the pocket L. In effect, the'cone 4: may be considered as a section of the container, since the cone wall serves to hold the liquid fully as much as do the walls of container 2 proper. So that we may. consider the parts 2 and 4 as constituting a sectional container in which one of the sections serves to support the ineansfor conducting. away the concentratesI accumulating in the opposite section during the periods of the diiferential in speed between the sections.

Having described my invention, what I claim is l.
