(Cl. 209-42) The present invention relates to amalgamators riage I3 is mounted for rotation. The upper sur~ for separating precious metals from ore and com prises essentially a vessel holding a body of mer cury and means for passing mixed pulverized ore face of the carriage is provided with a ring gear M' operatively engaged by a pinion l5 driven by a shaft [6 extending from the frame and operated and water through and in close contact with the by a suitable source of power. body of mercury in the vessel. Braces l1 extending upwardly from the carrier i3 and have their upper ends extended inwardly ‘ An object of the present invention is to provide an amalgamator of this character embodyinga , for ?xedly attaching to a mercury bowl or vessel horizontal plate mounted for rotation with the l8, said vessel being suspended from the bracket 10 vessel and upon which the pulp from the vessel within an opening 19 formed in the center of the carrier as will be apparent from an inspection is discharged, said plate being silver-coated and‘ having skimmers associated therewith for smoothing the pulp over the surface of the plate as the same is rotated to cause any of the precious ll metal laden mercury which might be discharged with the pulp to adhere to the plate for reclaim ing the same. A further object is to provide an apparatus of‘ this character of simple and practical construc tion, relatively inexpensive to manufacture and maintained in operation, efficient and reliable in performance and otherwise well adapted for the‘ purposes for which the same is intended. Other objects and advantages reside in the de 215* tails of construction and operation as more fully hereinafter described and claimed, reference be» ing had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout and in which:— 30 Figure 1 is a vertical sectional View through the apparatus. ' Figure 2 is a top plan view with the upper portion of the feed pipe shown in section. _ Figure 3 is a horizontal sectional view taken 35 substantially on a line 3—3 of Figure 1. Figure 4 is a bottom plan view. Figure 5 is a fragmentary sectional view taken substantially on a line 5—5 of Figure 2 and show Figure 6 is a plan view of the bottom of the bowl or vessel. Referring now to the drawings in detail, where ing for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a frame which includes bottom frame members 6 of substantially square shape, said bottom frame having an inner an~ nular frame ‘I connected to the bottom 6 by braces or arms 8. 2e: the plate. The outer edge of the trough termi nates on a plane below the surface of the plate to permit pulp to spill from the trough into an annual launder 28. A plurality of rif?es 30, formed of copper strips 30 are secured within the bottom of the launder 28, said launder also being provided with a. discharge chute 3| at one side thereof. A plurality of socket‘members 32 are formed on the upper surface of the bottom 20 of the ves 35 sel within which legs 33 are inserted formed on the bottom of a feed pipe 34 extending vertically in spaced relation from the walls of the pipe 22 into the vessel "3, said legs serving to support ingone of the riii‘les. 40 of Figure 1 of the drawings. A removable bottom 20 is threaded in the lower walls of the vessel, said walls tapering upwardly and terminating in an internally threaded neck A tubular discharge pipe 22 has its lower end extended within the neck 2| of the vessel, said pipe being externally threaded as at 23 in termediate its ends'for threaded engagement with the neck. The tubular member is secured in threadedly adjusted position by set screws 213. Adjacent the upper end of the tubular pipe 22 is ?xedly secured a horizontal annular plate 25 having a down-turned outer edge 26 formed into a trough 21 extending entirely around the edge of The frame also includes up in O standing frame members 9 connected by top frame members Ill. The annular bottom frame member ‘I is formed with an inwardly extending flange II, the upper surface of which is grooved for receiving a set 55 of ball bearings I2 upon which an annular car the bottom of the pipe above the bottom of the 40 vessel. The upper portion of the pipe is sup ported in vertical position within a ring member 35 connected to the upper frame members ll], said ring member also forming a raceway for a set of ball bearings 36 to facilitate rotation of the 45 feed pipe. To the upper end of the feed pipe is telescopically fitted a funnel or hopper 31 se cured in position by set screws 38. The frame members Ill extend radially from the ring member 35 and are provided with hinge members 39 from which arms 4|] are suspended, the lower ends of said arms having skimmers 4| attached thereto by a pin and slot connection 42 to permit vertical adjustment of said skimmers. The lower edge of the skimmers are positioned 55 2 2,127,418 in cooperating relation with the upper surface the carrier, a feed pipe having its lower end po of the plate 25 for a purpose as will presently be explained. The outer ends of the skimmers over sitioned in the vessel and extending upwardly in spaced relation from the wall of the discharge pipe, legs on the lower end of the pipe support ing the same on said bottom and maintaining the lower end of the pipe in concentrically spaced lie the trough 21 and are provided with depend— ing spaced apart agitator pins 43 which enter the trough to agitate the pulp therein. In the operation of the device the Vessel or bowl I8 is supplied with a quantity of quick silver or mercury and the ore is fed into the funnel or 10 hopper 3‘! and mixed with the mercury where the precious metal is extracted. By reason of the rotation of the carrier I 3 and vessel l8 the pulp is forced upwardly between the pipe 22 and pipe relation in said neck, and a horizontal rotatable plate secured to said discharge pipe below its upper edge and arranged for receiving pulp dis charged from the vessel. 10 3. In an amalgamator, a rotatable carrier, a It is believed the details of construction and op eration of the apparatus will be readily under vessel adapted to contain mercury and having a discharge upstanding neck, an upstanding dis charge pipe adjustably mounted on the neck, a removable bottom for the vessel, means support 15 ing the vesselv in a suspended position from the carrier, a feed pipe having its lower end posi tioned in the vessel and extending upwardly in spaced relation from the wall of the discharge pipe, legs on the lower end of the pipe support 20 ing the same on said bottom and maintaining the lower end of the pipe in concentrically spaced relation in said neck, and a horizontal rotatable plate secured to said discharge pipe below its up per edge and arranged for receiving pulp dis 25 charged from the vessel, a trough at the outer edge of the plate having a relatively low outer wall, and a launder positioned outwardly of the stood from the foregoing without further detail trough for receiving the pulp therefrom. 34 where it is discharged over the upper edge 15 of the last-named pipe onto the silver-plated cop per plate 25. The Skimmers 4| cause the dis— charged pulp to come into close contact with the surface of the plate to cause the adherence there to of any particles of precious laden mercury whichmight be discharged with the pulp. The pulp is then discharged into the trough or laun der 28 and discharged from the machine through the chute 3|. The ore which amalgamates with the mercury may be removed by removing the bottom 20 of the vessel and the supply of mer cury replenished. explanation.
