This invention relates to improvements in` concentrating machines 'of that `type which are especially adapted toy theseparation of inely divided and wet pulps, and whichem- )lov a traveling endless belton which isA` effected the separation of the worthless gangue from the valuable mineral contents.

The primary `object of the invention is to provide a'concentratingA machine of the above `kind which is extremely simple in construction and` adapted. to most eliiciently effect separation of the mineral from the gangue.l Y Another object is to provide an improved concentrating machine of the above kind havl ing simple andelicient means for readilyadjusting thev lateral inclination of theendless belt, whereby to secure most eiicient operation under various conditions of use.

Other objects will appear as the `nature of the 4invention is better understood, and

l ythe same consists in the novel form, combi-V` broken'away and in section.-

nation and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed. Y In the drawings: n

Figure l is atop plan View of a'concentrating machine embodying the present invention. Y

Figure 2 is an elevationalrview thereof, partly broken away and in section.

Figure 3 is an Venlarged end elevation looking toward'the right of Figurel, witliparts Figure 4t is an enlargedfragmentary devtail elevation Vlooking toward the right of Figure 3. Y j 1 x j VFigure 5 1s a iragmcntary sectional view or the belt; and Y Figure' is a fragmentary perspective view illustrating a manner of mounting the lower ends of the cross timbers ou the base iframe.

Referring more in detailto the drawings, I the present concentrating machine embodiesv a suitable open substantially rectangular base frame 5 upon which is adjustably mounted a supplemental frame 6` having a head'roller 7 and a tail roller 8 journaled therein around which passes an endless traveling belt 9, the rollers 7 and 8 being respectively mounted at opposite ends of the frame 6 asl shownA 192s. 1 semi No. 281,937;

clearly in Figures l and 2.1 The rollers 'Tand i 8 haveashafts suitablyv journaled in: l'zearings lO/fcarried` by the longitudinal rails-'of' the iame, andthe bearings yfor the shaft ofther tail .roller S. are preferably 'adj ustable longi- .tudinally' of lthe machine inorder to adjust Vthe. tension of thebelt p v9 Vin anlobvious andl well'lznown manner.. f V' ,lhc franie has corneruprights orlegsv ll securedfat their lower .ends upon cross tiingr hers or bars-12 whoseends, adjacentjone side ofthe machine are loosely mounted upon the adjacent longitudinaly yrail ofthe basefirame 5 so as to be capable' ofl vertical swingingmovement for adjustment, althoughV restrained from longitudinal oli-.lateral shifting ,1 n

`This fniayrbe accomplished inanyfsuitable way but is'vshown as veffected. byproviding the adjacent.longitudinal rail of the base frame 5 with pairs 'of upwardly projecting pins 15S-'loosely extending through in apertures in crosspieces 14 provided on the adj acentends of the cross bars A12j asfshowii inyFigureslillld' 6.' The'other ends of the rcross bars l2 atthe opposite side of the inachineare c provided on their undersides :Wit-h wedge V.blocks l5 having inclined lower edges,aiid y shdably mounted in bearings 16v upon the n outerside of the adjacent longitudinal grail n of therbase frame '5 for movement loiigitu#I '.dinally ofthe machinefis a rod 17w-hich'car- .ries furtherwedge blocks 18 having ii'iclinek'l y i upper edges andv cooperating with the-respeci tive wedge blocks '15 whereby to adjust the .lateral inclination o'lilthe frame 6 and the belt 9 upon longitudinal adjustment of the rodV 17 and its wedge blocks .18. This construction is more particularly shown in'Figures 3 and. 4l, and'iu order tofacilitate manual. longitudinal sliding adjustment of the rod 17, a rack bar 19 is fixed to the latter intermediate Vits ends for actuation by a pinion segment 20 which meshes therewith andV is carried by a hand lever 2l` pivoted` as aty 22 to the-basev frame 5 vabove the rack bar 19,. `As indicated i rin'Figure 3V andclearly shown in Figure 5,l

kthe edge of thelceltv 9 atthe higher side of the machine is provided with an Vinwardly projecting continuous iang'eQB'` adaptedV to engage theedges orf; the rollersf? and 8 at the higher side of the machine whereby the belt is prevented from slipping sidewise toward the lower side Aof the frame 6.

At the receiving end of the belt is prov ided a supply launder 24 which discharges into the feed box 25 arrangedalong the upper edge or side portion of thepbelt 9 and provided with discharge openingslQ.`V The feed bei; 25 preferably forms a partitioned continuation of a c ear water box 27 extending along the upper side edge portionrof the belt and provided withdischarge openings 9.8. The wash water is'suppliedtothe clear water box 27 from any suitable source by the water supply pipe 29.

Beneath the belt 9 at the tail end of the machine is arranged a transverse water pipe 30 Ahaving suitable perforations through which the water discharges in jets upon the belt `9 atthe underside of the tail'roller 8,

Y to thereby wash the concentrates from the 1 belt into a concentrate box 3l suitably; placed and supported at the tail end of the` belt. Suitable means is provided for 'actuating the belt from the tail roller S, and asshown said roller is provided with a drive wheel or gear 32 adapted to be suitably connected to any suitable source of power.

The operation of the machine is as fellows:

Thev belt travels in the direction yof the arrow d of Figure l from the head roller tov the ltail roller, and the pulp or material to be concentrated is discharged from the openings 26 in the feed bex 25 ontothe belt '9. The forward travel of the belt causes `the pulp to take a diagonalV course across the belt in the direction indicated by the arrow lines b in Figure l, toward the catch laundei 33. The heavier matter at once settles on the belt, while the balance flows off intothe tailing` or catch launder 33. rlhe forward travel 'elt carriesthe material opposite the fresh water .box 27 from which the fresh water washes ot" the materials of lighterspeciiic gravity into the catch launder 33, leaving the valuable and heavier material attached and clinging to the belt 9. The travel of the belt 9 continues to carryforward the clingingand adhering` mineral onto and over the'A tail roller S'where it eventually is washed from the belt into the concentrate bof; 31 by the jets of water from 'the pipe 30; The

above operation is uniform and continuous,V

and the amount oit'- worthless `gangue rejected can be increased by varyingthe inclination at which the belt lies, by varying the amount of fresh water supplied for washing, or by varying the speed at which the belt is caused to travel. i

Minor changes may be made without de-` parting from the spirit and scope of the in vention as claimed. t
