BENJAMIN LONG, OF

BOULDER, COLORADO.

SEPARATOR.

To all whom it may concern:

Be it known that I, BENJAMIN LONG, a citizen of the United States of America, residing at Boulder, in the county of Boulder and State of Colorado, have invented certain new and useful Improvements in Separators, of which the following is a specification.

My invention relates to new and useful improvements in ore separators and its object resides in the provision of a mechanism of simple construction by which the value-bearing particles of pulverized ores or placer sand are speedily and cleanly separated from the non-metalliferous matter with which they are associated. I attain this object by the mechanism illustrated in the accompanying drawings in the various views of which like parts are similarly designated and in which Figure 1 represents a plan view of the apparatus, Fig. 2, a side elevation of the same, Fig. 3, an enlarged end view of the drum in which the ore is treated, Fig. 4, a vertical sect-ion through the drum taken along the line 44, Fig. 3, and Fig. 5, a fragmentary perspective view of the launder by which the wash water is introduced into the drum.

Referring to the drawings by numerical reference characters, 2 designates a rectangular frame upon which the various parts comprised in the improved separator, are supported. A hollow, cylindrical drum 3 disposed between the side-beams 4 of the frame, is, by means of two circular rails 5 which are secured upon its circumferential surface, revolubly supported upon four flanged wheels 6 which are mounted in pairs upon parallel axles 7. The axles 7 are rotatably supported in bearing boxes 8 on the side sills 9 of the frame 2 and they are connected to rotate in unison, by means of an endless chain 10 which engages with sprocket wheels 12 on the respective axles.

In the operation of the apparatus a rotatory movement is imparted to one of the axles 7 through the instrumentality of a cone pulley 13 which being secured upon said axle, connects by means of an endless belt 14 with a corresponding pulley 13*, which is reversely mounted upon a line shaft 15 supported in boxes 16 upon the side beams 4 0f theframe. A second shaft 17, which is mounted in boxes 18 on the up- Specification of Letters Patent.

carries two

pulleys

20 and 21, one bf which is connected by means of a belt 22 with a conveniently located motor while the other connects by means of a belt 23 with a. pulley 24 on the shaft 15.

The axle 7, opposite to the one which carries the cone pulley 13, is provided with a sprocket wheel 25 which connects by means of an endless chain 26, with a corresponding wheel 27 on a shaft 28, which is mounted in boxes on the beams 4. This shaft 28 carries near one of its extremities, a toothed wheel 29 for the operation of an inclined, endless conveyer 30 through a trough 31, which at its upper extremity, connects with an oppositely inclined chute 32. V

The material to be treated is elevated by the conveyor to the upper end of the chute 32 which, by means of an angularly directed spout 33 at its lower extremity, discharges it into the interior of the drum at a point in its bottom portion, rearward with relation to the direction in which the drum revolves.

The drum 3 is provided at its feed-end, with an inwardly extending circular flange 34 which prevents the material from spilling over its edge and it is lined with a sheet of rubber 35, secured upon a backing of wire netting 36 which is fastened upon the interior surface of the drum, between the end.

During the operation of the apparatus, wash-water is continuously introduced into the interior of the drum at is forward side, by means of a plurality of horizontally alined nozzles 38 on a launder 39 which extends transversely through the drum. The jets of water emitted through the nozzles 38 impinge upon the inner surface of the drum along a line somewhat above the horizontal plane flowing downwardly along said surface, meets the mass of ore which, during the movement of the drum in the direction of the arrow in Fig. 3, adheres to the rubber lining and moves upwardly toward the line along which the water impinges upon the same.

While the downwardly flowing water washes the light worthless matter contained in the ore toward the bottom of the drum, the heavier valuable constituents thereof, adhere to the rubber at the forward side flange 34 and a ring 37 at the discharge extending through its axis, and the water' the;axle:43 near its extremities, are,like=the of the same from where they are subsefluently removed through the instrumental- 1ty of an appliance which, at a predetermined point in the revolution of the drum,

intercepts the flow of water along a linev between the bottom of the drum where the ta lings are collected and the portion of its surface-to which the values adhere.

The appliance above referred to which after it has dammed the flow of water, re-

.ceives the values precipitated thereby, and conveys them to a point beyond the discharge .endof the ,drum, consists of a-V- shaped trough 40, articulately secured by meansof hinges 41, atthe lower end ofan inclined frame 42, which at its upper Iextremity .is pivotally mounted upon anaxle 43, .which is rigidly securedupon the side beamst4: ofthe supporting structure .2, above ..and ;in vertical 'alinement with the axis of 1.;hetrough'40 is resiliently held inits normal' po i on in whic i ss o ardedge .40 i 1 .naoedzf om t interior surface of the .d-mmahy mea s o .a. a p ng- 44, the up- ;perrend of :whiohis secured to one of-the cross-straps of the skeleton iframe 42, and the normal angle of inclination of 'the latterQi-s determined by means of a stop-.rod

' "The above described action is automatirespective levers 49 .and whose upper ends ese,5s1

extend loosel into the respective sleeves. Stops 56, a justably fastened upon the beams 4, serve to prevent excessive movement of the levers 49.

As the operation of my improved ore separator has been referred to at intervals in the course of the foregoing description, it will only be necessary to outline it briefly at this point.

lVhen the drum is rotated in the direction of the arrow in Fig. 3,.by themovement of the wheelsG upon whichit is supported thc water flowing downwardly along its interior SllIfiLCBlIlTthG opposite direction, se arates, ashereinbeforeexplained, the .valua le particlesfrom the worthless constituents of'the upwardly moving mass of material which was introduced into the drulnth'rough the spout at the end of the chute 32. Once during each revolution of .the 1 drum 2, .the levers -49 are moved about their fulcrum, by

the engagement of the tappets 50 with:thc rollers 51.at;-their upper ends, and t hesavings-trough, 40 isin consequence movedabout its hinges on the iframe 42,, until itsafonward edge 40* frictionally ,engagesqthe ;r,-ubberlining of thedrunitointereept the downward flow of the wash-water introduced into the drum throughzthe nozzles 38 ;of {the launder 39. During the continued moVemenbOf the drum, the-trough 40 is, by reason, of--i ts ifrictional engagement with ,the .r ubb er..lini,ng .andthe yielding connectionrbetweenithe rollers 51 .and :the respective levers 49, moved upwardly toward the line along which the jects of wash-water impinge upon the interior surface of the (drum, until ;'tl1e'- tappets .50 disengage the rollers, when the spring 44 returns the trough to its normal position. andthe frame .42 'deseendsby; force of gravity upon ithe stoprrod .45.

{Fhe waluable particles of the ore collected upon the surface of the drum above .the trough 4:0,;31'6 during vthe ;above described operation washed into the latter and {discharged into a receptacle placed below the end of ,thetrough which protrudes beyond the 'discharge'endof .the drum as shown in Fig. 1-of-the drawings.

It-will be understood that-by the proper adjustment of the .stop 45,;and the .applicationof more than ,one tappet at each end of the. drum, the position .ofthe (trough 40, the extentof its-movement, and the number of its operations duringeach revolution 'of the drum, may be ,varied in. accordance with the character of the materialtobetreated.

The upwardly moving conveyer 30,.separates the muddy :water from the material before it is fed into the drum, and the material is consequently treated. only with clear water which greatly facilitates the process of separating the values contained therein from the gangue.
