AMALGAMATOR.

To all whom it may concern:

\ Be it known that I, HARRY LOEVEN, a citizen of the United States, and a resident of Douglas, in the county of Cochise and State of Arizona, have invented certain new and useful Improvements in Amalgamators, of which the following is a specification.

My invention relates generally to amalgamators which are particularly adapted for the recovery of gold from ore pulp although it is to be understood that I am not necessarily restricted to this particular adaptation.

The purpose of my invention is the provision of an amalgamator in which the ore pulp is treated'within a rotated vessel which is disposed on an incline, and is provided the pulp is successively fed to effect a complete recovery of the gold. .f

I will describe one form of amalgamator embodying my invention and will then point out the novel features in claims. In the accompanying drawings: Figure 1 is a view showing in front elevation one form of amalgamator embodying my invention, and one form of supporting and driving means therefor;

Figure 2 is a view showing in side elevation of the amalgamator and driving means shown in Figure 1;

Figure 3 is a detail perspective view of the amalgamator shown f in the preceding views; r s

Figure 4 is a central longitudinal sectional view of Figure 8; and

Figures 5 and 6 are transverse sectional views taken on the lines 5.5 ,and 66, respectively, of Figure 4.

Similar reference characters refer to similar parts in each of the several views.

Referring specifically to the drawings, and particularly to Figures 1 and 2, 15 designates a base to which is fixed supporting standards 16 and 16 in which is journaled the opposite ends of a shaft 17. As shown in Figure 1, the standards 16 and 16 are of different lengths and the right-hand end of Specification of Letters Patent. Patented 30, 1922. Application filed August 4, 1920. Serial 401,096. i i

nism in the present instance comprises a shaft 19 journaledin standards 20 and disposed above the shaft 17 as clearly shown. The lower end of the shaft 19, is provided with a pulley 21 which is fixed to the shaft and a second pulley 22 which is loosely mounted on'th e shaft and constitutes an idler. The shaft 19 also carries a driving pulley 23 to which any suitable power may be applied for rotating the same, as will be. understood. The shaft 19 is operatively con,

nected to the shaft 17 by means of an end- 1 less belt 24: which is'trained about the pulleys 18 and 21. When it is desired to dis connect the drivingshaft 19 from the shaft nected to other side plates'25i. The ends of;

the vessel are partly closed by end plates 26 and 26 which are secured to the plates 25 and 25 and'are formed with relatively large Openings 27 and 27 'res,pectively. As illustrated'to advantage in Figure 3, the shaft 17 extendsv axially through the vessel and the latter is secured to the same forrotation therewith by means of intersecting cross bars 28 which are secured within thevessel and are disposed 'within suitable recesses formedfin the shaft. The cross bars 128' are secured within the recessed. portions of the shaft 17 by means of bolts 29 so that a rigid connection is formed .between the" vessel and the shaft to cause the former torotate with thelatter. It will be noted that the cross bars 28 are disposed adjacentthe opposite ends of the vessel so that ready access may be had t the bolts 29 to connect or disconnect the vessel from the shaft.

7 To effect a. complete recovery of the gold or other precious ore from ore pulp the amalgamator is provided interiorly of the vessel with a plurality of rifiles or partitions 30 and 30. As shown in Figures 4, 5 and 6, the rifiles 30 are arranged in pairs, with the rifiies of each pair spaced apart and connecting the plates 25 of the vessel. The riflength of the vessel thus providing a plu-' rality of compartments K any two of which are in communication through the openin s31. v.

n the operation of the amalgamator,. the several compartments K are partially filled with quicksilver, whereupon the belt 2 L which is normally trained about the idle pulley 22 is shifted to the pulley 21 so that the shaftl7 is caused to slowly rotate. By virtue of the riflles 30 and 30 the quicksilver in any one of the compartments is maintained therein during rotation of the vessel, it being understood that the quantity. of the quicksilver in each compartment is suffi cient to perform the recovering operation without spilling and passing to the next compartment. The ore pulp is introduced intothe vessel at its upper end through the opening 27, a suitable trough T being provided "for this purpose. \Vith the amalgamator slowly rotating the ore pulp is successively fed through the several compartments and finally exits through theopening 27 During the passage of the ore pulp, the quicksilver is thrown from one s de of the vessel to the other thereby cau'singthe same to collect the. particles of gold, the tailings being left to pass through theseveral openings 31 i and outwardly out of the opening 27. Be-

cause of' the several compartments Kand the recoverlng material contained therein, it is obvious that the ore pulp is: successively subjected to a. plurality of recovering processesso that during the passage of the same through the amalgamator a complete recoveryof the gold is effected.

4 As shown in. Figure 5, one of the walls 25 is formed with a longitudinally extending slot S which is cut in the wall at a tangent ofacircle with the axis of the shaft 17 I as a center. Since the amalgamator rotates in the direction of the arrow in Figure 5,. the

' material contained. within the vessel will not be discharged through the slot S because the transverseinclination of the latteris such that the material, although entering the slot when the corresponding side plate is inverted will be immediately returned to. the vessel when such plate moves to a'vertica l position. When, however, it isv desired to extract the gold and quicksilver. from the vessel the rotation'of the latter is discontinued and then turned slowly in the opposite direction" by hand. This causes the gold and '-quicksilver to be discharged through the slot S as the inclination of the latter is now such that the material enteringthe slot when the corresponding side plate is inverted gravitates from the slot and exte riorly of the vessel-when the side plate moves to a vertical position.

Although I have herein shown and de scribed only one form of amalgamator embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.
