socket bearing 42 is located' within the said box and is engaged by the -set screws 43, 44

vwhichare respectively in en agement with the ' walls 36 and 37, and the a justin screws 145, 46 vwhich areA respectively in t readed 'engagement with the walls 38 and 39.

- The bearing 42 engages the ball l50, which has'an axial opening for the pin 51",' that supports the boss 52 of. the oscillating and 'undulating frame 58 with the lugs'54 and arms 55.

In the lugs 54 are formed vthe cavlties 56 and 57. A secondary boss 58A eX-l tendsfrom the boss 52 andsupports the'discharge pipe 59. IVibratoxy stanchionsO with thelcollars G1 and threaded ends A'(52 with the nutsI 63, are each in a pair of accompanying'openings in the arnis 2O of the said' plate and feet 29 of the pyramidal frame. The cavities 56, 57 allow the stan-v chions in their normal positions to incline toward or from the axial'center of the machine.

'The frame 53, supports the main trough',Y

G6 with the pan 67, the trough 68 With the pan G9 and the trough 70.with the 'pan 71. The latter has fastened thereto the threaded fiange 72.

A valve 74 with the longitudinal port 75 has a threaded boss 76 which engages .the Y vflange 72 and a threaded boss 77 which en gages the boss .52. 'A cross port 78' joins Vwith the longitudinalport 7 5A and has at one `end the threaded boss 79- for the coupling 80,

and-at the otherend is formed a stuffing box l 8]. the packing 82 andthe screw Cap 83.

` It valve rod enters the cross port 78andv extends through a guide 8G that is supported in the walls of the troughs GG, G8 and 70. pivot bi'acket`87, to which is pivotcd the-link 8S, and to the latter is piv-oted the valve op l A pjn 9() connects the said handle `with the valve rod S5, and a'.;

erating handle 89.

From the trough (i6 extends a.

guide 91 extends from the said trough (Sii for' the-handle S9, and to which said handle can he' pinned. An inlet pipe J2 is connected up. with the cross port 78 hy means of the conf4 pling 8U. Feedingr and stirring balls 93v are located in the pan 7l. 'lhc pan (i9 of the -rongh (58 has extending from its lower suraXial opening 98 and the openings 99. Feeding and stirring balls 100 are supported on the pan 69. To the lower face ofthe pan 67 is fastened the flange 101 with the port 102.

I nipple 108 with the coupling 109 and flexible discharge tubing 110 extends from the piping 107. A

In the bottom of the trough 66 are formed openings 115 for the nipples 116 and the latter areconnected to the inclined piping 117: A; nipple 118 with the coupling 119 and flexible tubing 120 extends from the piping 117 A tailings trough 124 with the inclined bottom125 extends around and is supported on the trough 66 and has extending therefrom the outletconduit 126'. A coupling 127 connects flexible tubing 128 to said conduit 126. A re-inforcing ring 130 is fastened to the outer edge of the trough 124, and to the inner upper edge of said trough is fastened a ring frame with the ring 131,

.arms 132 having the flanges 11,.) with the depressed portions 134 and tue lugs 135. An axial threaded sleeve 140 is formed with the arms 132, and a screen 142 is supported on said arms and held in place by means of i the standingr bolts 143, extending from the .lugs 135, and the wing nuts 144. A'dellector 150 is fastened to the lower edges of the arms 132 and hasthe large opening 151.v A'

charging sleeve' 155 is supported on the arms 132.

The axial sleeve 140 has in threaded engagement therewith on the inside thereof' the feed sleeve 156, and on theoutside thereof the protecting sleeve 157. On the sleeve 156 is clamped the ring 158 with thel adjusting handle 159. A. head nut 165 is supported on the sleeve 156 and carries the threaded bushing 106 on the upper surface thereof. A lock nut 167 clamps the bushing '106 on the head .nut 165. A ring 168 with the handle 169 `is fastened to the bushing 166. A screw valve 170 with the axial port' 171, isY in threaded engagement with the bushing 166. lt has formed at it-sl lower end the valve tace172 and the guide pin 173 which engages the opening 98, of the cage 97. The valve face 172 registers with the4 a nipple 183 which carries a coupling 184 for the flexible tube or hose 185.

A water hose. 190 is coupled by' means of the.eoupling 191 to the piping 192- which has fitted thereto the valve 193. Branch piping 194`With the valve 195 extends from the piping 192 andv leads to the screw valve' 170. The piping 192 passes through the troughs 124, 66 and has connected thereto the perforated outlet ring 196 which encirclcs the screw valve 170.

To operate the invention the driving shaft 23 is rotated by means of the pulley 34 and belt not shown. This gives a vibratory and undulating movement 4to the frame 53 and the appurtenances, connected thereto. The inclined vibratory stanchions 60 in their positions as shown on the drawings.

allow the frame 53 to descend from its normal horizontal position while moving. Should it be desired to allow said frame during its movements to risefrom its normal position, the stanchions are located with their upper ends in the cavities 57 to incline them outwardly. The material, metal bearing sand and the like is charged v into the charging sleeve 155 with water, and

from which it drops upon the screen 142.v

The 'screen separates the coaiser por-tions of the charge .like gravel, which are deposited into the gravel trough 180, and the material that enters said trough is dischargedl therefrom through the nipple,182 and the flexible hose 185. The bulk of the material finds its way to the screen adjacent the depressed portions 134 of the arms 132. Thev small particles of the material pass through the mesh of the screen at said portions 134 and lill the pan 67. The floating metal or slimes of the charge in the pan 67 becomes attached to the deflector 150 during the movements of the. apparatus, and as the charge tends to overflow from said pan 67 to enter the tailings trough 124, and the said slimes are subsequently removed from the deflcctor. The said deflector directs the particles of material toward the central portion of the pan 67 andv prevents the major portion of the shines overflowing from said pan. The material in the trough 124 is disexible tubing 128.

The feeding and stirring balls 103 in the pan 67, stir the cencentrate therein and the material that drops from the Vdetiector,a1id feeds the-charge in said pan 67 through the .port 102- by reason of the oscillating andl unv dulating movement imparted tofthe pan.

. The protecting sleeve 157 around which said The concentrate next drops into the o-au 39,

Where it is acted upon by the fe; stirring balls 190 in a manner sim-.iai functions of the balls 103. Sprays' of water are discharged from the outlet lring 196,

concentrate in tlye pan 69"and force. the saine into the trenghtt, from which they are discharged throughV the openings 115 on their way through the nipples 116, inclined piping 117 and flexible tubing 120. The heavy concentrates and metals in the pan 69 are discharged therefrom through the port 96,

the openii'ig;r et which is regulated by the location of the valve face 172 of the screw 'lhe location of the latter` is eentrolled by the handle 16%). The metals and heavy concentrates now drop into the pan 7l, passing through the openings 9S) o f the cage 9T, and where theyar'e acted upon by the balls 93 as recited .tor the balls already described. "vlhe light portions of the material in the pan 71 are-discharged into'the trough GS, t'roin which the are led b v nie-ans of the nipples 10G into the .inclined piping 10T, and lr'iun the. latter they are led away by the tubingl'lO. rlhe metals in the pan 7l. remain therein until the valve rod 85 is pulled out by means ot the handle S9, when com# muuiration is made between theports'i' and 7S oI' the. valve Tit. A stream ot water is then led by the piping llet-iuto the axial port llot the screw valve 170, to wash any adhei-ingr roneentrate from the metals land which is led away by the tubing 110, and the metals are discharged through the discharge piping 5S), Ail'ter the metal has been discharged from the pan'Tl, the valve Ti is cleaned by forcing water.tliercthrough by means of the piping 92. The said water is discharged through the piping,T 5t).

The invention may be modified by only using; the delleetor 150 with any one olf the pans (i7, G9, 7l, or the detlector may be omitted and any two4 of the. pans may be Having described my invention what l. desire to secure by Letters Patent and claim is:
