; 0 all whom concern- V vBe it known that I, MERL of Colorado Springs, the conntyfotEl Paso and State of Coloradofliaye invented certain new and useful Improye nents: in p Separators, OfWhlCh the following is a'specification. p 1 t This invention relatestoa separatorfl The invention more. particularly relates to an apparatus for separatinga conglomerate of solids consisting in materials having dif ,ferent specific gravities such; as fOLlD Qlj ll'l niining operations for redeeming precious metals from sand and grayelbeds or from tailings of a nilne or the like.

The invention has fr ltsobjec't to provide an apparatus whereby the different materlals having different specific gra'vities nay- :ugal force, and'the specific" gravities of the inaterials being separatedi Pr'eferablT a 7 upon fcog wheel ltislikewise mounted upon the shaft above the. cog wheel 13 and is adapted to support the supporting member 10, I i e J The pans and P are supp orted'bythe members 10 and 11. a Each pan is helical pair of helical pans or tables are employed, said pans being concentric toi'each other and 'turnable froina common means. Also each pan is inclined transversely viz, fromgits' inner periphery upwardly and toward its outer periphery. The pans, in each instance,

are alsoiadj ustable so that'the end theret into which the material is deposited may be brought closer to the axis of rotation than the discharge end of saidpah. Each'pan separately operates for, separation of materials. The pans are rotated and the nia' terial in workingits way toward thedischarge end of each ,pan will be separatedinto diiierent strata. or Zones; the outermost zone represei'iting the material having the greatest specificgravitfl the Zone adjacent thereto representing the material having the next greatest specific gravity, and so on, to the inner periphery ofthef pan. 1

"The invention] is illustrated by ,w'ayofi I example in 1 the: accompanying drawings; in

Figure l 're'presents a lLQPHPlt-LILVIQW the p p M. NEWTON, a citizen of theUnited States, and: a resident present invention.

Figure-4 is a top plan viewof a i nodified form of apparatus. Referring to fthedrawings niore larly,in Figures 1 to 8 inclusive, P andl indicates generallythe'two helical pans; S

fgenerally indicates a shaft which is suitably 1 supported'a'tits" lower end for rotation gand is a Vertical, sectional iew of the particuatB is generally indicated a receivingbin into which theniaterials afterbein gdivide'd or separated may ybe deposited; .Upon the ,shaitthere is turnably mountediagpairof supporting .ni'embers 10 andll, the supporting member 10 being positioned above the member 11; Immediately below" the supporting member 11 there is positioneda colhr 12 adapted tohold the member-11' against downward, movement, and above the supi portin inernber there is loosely mounted the shaft S arogwheel 13. A similar "or spiral information and its innersurface further formed with a projection or arm 'ie by which the same; is pivota'lly connected to the associated outer end of the lower up,

port 11 by a bolt 19. Intermediate the s iipportingnieinber ll'and the bottom of each span there is interposed a bar 2-0 whichis setoured to the pan by a rivet 21: and tli'ebolt '19 in the manner illustratedin" Figure 3.

The inner end of each bar 20 terminates in I a rack bar 21 which is arcuate"inshapeand, j-in'constant'ineshwith the cog wheelfli lf There is also provided a bar 22 for each pan which corresponds to theba-r 20 h {formed upon its inner end, in each instan I an arcuate shaped rack bar which is adapted to mesh with the cog wheel 14. The

. bar 22 is secured to the retaining flange 16 The upper supporting member is formeil upon its one side with an arm or lug 26 in which there is mounted a crank 2?,sa1d

crank carrying a pinion 28 adapted to mesh with the cog wheel l l. As is obvious by this arrangement with the rotation of the pinion 28, the pans P and P may be swung upon their pivotal connections with the frame openings 30 in the pinion 28 for locking the pinion in adjusted position.

As seen in Figure 1, the ends of the pan P overlap the ends of the pan P Above the pans in any suitable position there'may be arranged a hopper H. This hopper may be supported in any suitable manner, not shown, and have a spout F extending there from to each of the pans P and P The spout F in eachinstance should be distensible so that the same may be adjusted with the pans, that is, with relation to the shaft S. The spout F'for the, pan P is adapted to discharge material into the pan at a point adjacent its highest end and against its upper peripheral edge, that is, at a point directly beneath the retaining flange 16. The

spout F or pan P discharges material into said pan at asimilarpoint.

The bin B- should consists in a plurality of annular compartments as indicated at C, Figure 3. The outermost compartment is of such width that upon adjusting the pans with respect to the shaft S, the material discharged from a point adjacent the ipper edgeofeach pan will be at all times deposited in this compartment. The outermost compartment C will therefore receive the A -material having the greatest specific gravity. The compartmentadjacent thereto will receive the material having the next to the greatest specific gravity and the innermost compartment will receive the lightest ma terial.

pletecircle and its receiving end 30 being innermost and adapted to receive materials from the spout F which communicates with the hopper H. The discharging end 31 of the pan is disposed over a bin B which is divided into different compartments C, each compartment representing a complete circle and adaptedto receive a certain material separated in the pan P In operating the present apparatus, the. shaft S may be manually rotated with a crank C or with other power" means.

The operation of the present apparatus is as follows: The material to be separated is dumped into the hopper H and from thence will proceed into the upper ends of the pans P and P The shaft S is preferably rotated in'clockwise direction. As the materials proceed to move downwardly in each pan, so carried by gravity, the centrifugal force will urge the materials having the greatest spe cific: gravity toward the outer edge of the pan. The retaining flange 16 prevents the escape of this material.

The heaviest material which will occur adjacent the outer edge of each pan will cling to the bottom of the pan and move longitudinally of the pan. The materials will separate themselves into different zones, the lighter materials moving toward the A shaft S and previous to the time of said materials reaching the discharge end of the pans they will be entirely separated in a uniform manner. The outermost zone as before stated will be composed of material having the greatest specific gravity and the innermost Zone of material being of the least specific gravity. The different materials will sepaof the material begins immediately after the same has been deposited in the pans, that is, the heavier materials remain adjacent the outer edge of the pans and move longitudinally and downwardly while the lighter particles move longitudinally of the pans and also move inwardly toward the axis of rotation of the pans. i

Furthermore by the pans rotating in a direction similar to the movement of the material a greater amount of work is performed that is, due to the pans moving at a higher rate of speed than the flow of the material the surface of the pans oppose the movement of the material and thus to cause a slower and more thorough stratification of the material. I

From that heretoforerecited it is believed it obvious that if the pans would be rotated in an anti-clockwise direction and material deposited in'the lower ends thereof, the said material would move upwardly and in a discharged from the upper end of the pans.

I similar manner; the materialthen would be By an arrangement of this nature, a device of this character could be utilized for lifting material, that is, by rotating the pans in an anti-clockwise direction and permitting material to ener the lower ends thereof.
