Other objects and'advantages not specifi-.

cally mentioned will become apparent during the course of the following detailed description when read inconjunction with the accompanying drawings which form a part of this specification and in. which:

Figure 1 is a vertical sectional view of an apparatus embodying my invention;

Fig. 2 is a top plan viewthereof and Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 1.

Referring now to the drawings in detail, wherein like numerals refer to like parts throughout the same, 5 indicates a liquid tank of any desired shape or capacity from which liquid is delivered under pressure to a circular classifying tank 6. The liquid is O drawn from the tank 5 through the intake conduit 7 of a motor driven centrifugal pump 8. The pump 8 is shown as being driven from an electric motor 9 through a shaft 10 although any other available source of power may be used.

The liquid is delivered from the pump 8 through a feedpipe 11 into a drum shaped header 12 carried on the bottom'wall- 13 of the tank 6. The header 12 is provided with a plurality of radially extending conduits 14 which extend horizontally from the side of the head 12. The conduits may be of varying length and number to suit different conditions in the operation of the device and each terminates in a circumferentially directed discharge nozzle or jet 15. The nozzles15 are all directed in the same circumferential direction so as to set up a whirling or rotary motion of the liquid mass in the tank 6.

PATENT oer-ice The mixture of material to be classified is fed'from a feed chute 16 into an upright tubular feed well 17 from-the lower end of which it is discharged onto a distributing cone 18, the apex of which'is centrally located with respect to the. lower end of the. well 17 As the material is evenly distributed into the liquid current from the. circular edge 19 of the cone, 18 it is-efliciently divided, the lighter portions being carried around and upwardly and the heavier sludge mate} rial beingprecipitated to the'bottoni 13 from which it is discharged through bottom refuse discharge valves20 or side discharge valves As the material of less specific gravity is carried upwardlylby the liquid current, it is discharged over the top edge 22'of the tank 6 onto anannular overflow launder or spout 23. The launder is disposed at an angle (so as to dischargethe overflow from the spout 24 thereof onto a dewatering shaker screen 25. The screen 25 is providedwith the prop er sized mesh to separate the cleaned material from the overflowing liquid mixture and is suitably supported preferably above the tank 5 by appropriate upright members 26.

.The mixture'of fluid and material which passes through the shaking screen 25 is caught bya funnel shaped hopper 27 and discharged throughthe spout 28 into the tank 5. It will be'noted that-the shaking .scre'enj25 is inclined from the spout 24:;to-

ward a suitable delivery chute 29 uponwhich the washed product shaking screen. k

material to be operated upon, the number; size and angularity of the nozzles 15 may be v I V is delivered from the z It will be understood that dependingonthe v I ing through which'the agitating liquid must flow in passing upwardly from the nozzles 15, may be varied to'regulate; the velocity" of liquid passing throughfthe opening beico tween said edge and the sides of the tank 6. The results of the separation may also be controlled through regulation of the speed of the motor 9 or throttling of the pump 8. Inthe operation of the device and in carrying out my process, the tank 5 being filled with water or other suitable liquid, the pump 8 is placed in operation to draw the water from the tank and discharge the same through the pipe 11 into the header 12 from whence it is discharged under pressure through the nozzles 15. When the classifying tank 6 fills to overflowing, the material to be operated upon is fed into the well 17. Under the action of the pressure discharge from the nozzles 15, the water in the tank assumes a whirling or rotary motion, the current passing upwardly in a spiralpath. The ma- 1 terial falls from the well 17 onto the cone 18 g, and as it rides off of the distributing edge 19 thereof is caught up by the rising current, the material of less specific gravity being whirled to the top and over the edge 22 of the tank. The sludge and heavy matter falling to the bottom will be slowly swept around due to the rotary motion of the fluid massand may be readily removed through the discharge valves. 1 r

As the overflow from the tank '6 carrying the separated materialis discharged by the launder 23 onto the shaking'screen 25, another separation takes place, the Water and smaller particles being discharged back to the tank whilethe wanted washed product is delivered to a point of deposit.

While apreferred embodiment of the inventionhas been shown and described, it will be understood that various changes in the details of construction may be made without 4-) departing from the spirit of the invention as defined by the appended claims. 1
