To all whom it may comer-n5 Be it known that I, RoYER a citizen of the United Colwyn, in the county of Delaware and State of Pennsylvania, have invented certain new and'useful Improvements in Apparatus for Pulverizing and Amalgamating Ores, of which thefollowing is a specifica- 'LUGKEN AGH, States, residing at My invention has relation to an automatic apparatus for pulverizing and amalgamating ores gold and silver, by causing mechanical ama gamation of their entrained values in their pulverized state with an amalgamating body by the direct active commingling of the mechanical means with the amalgama ing body and which act to free tailings or gangue from the ore matter, aided by induced air i currents, while themechanical means act upon the ore yalues economically and efliciently free the values as well as permit the impelled freed tailings be discharged without manual means employed to accomplish such results," in the series of operations progressively acti or gangue to ing upon said pulverized ore matter.

tion will be more following description taken in Figure 1, is a the combined In the drawings, referring to Figs. 1., t0 3, 5, is a combined pulverizer and amalgalnator, consisting of sectional castings 6 and'fl 7, supported upon each other and within: parts of the appaare confined 9, is a vertical bracket supported upon the; which is supported a hopper 10, f. shaft 11, carrying at I which the active Working ratus for the defined results,

a miter-gear 14, meshing This shaft carries a pulley 17 for the reception of-a belt, not shown. 18,

to separate their values, mainly j gam in transit, thereby to ceiving and 1 mg 6. The nature and scope of my said inven-: fully understood from the connection a with the accompanying drawings, in which I vertical section of an appa- 1 ratus embodying main features of my said; respectively,

amalgamator on the lines l; and Fig. 4, is a} into the chamber amalgamator cona' dry pulverized condition prior to its located within the-supported casting 7 and designated as an ore crushing or grinding chamber and within which a grinding or crushing device 19, is mounted to'be gyrated therein by means of shafts 20 and 20, projecting from both ends of the device.

GOLWYN, PENNSYLVANIA, AS SIGNOR T0 BORINDUM EXT BAG The device 19, is preferably in form that of two truncated cones or frustums of cones placed .base to base. The upper end of the shaft 20, preferably formed into a ball. 21, ens e rang crank-arm 12, and the opposite shaft 20*, extends through a cone-shape portion of a casting 22, as illustrated in Fig. 1, forming the dish-shaped bottom or race for an amalgamatln body 23, such as mercury or amalgam, a also is therein mounted a series of hardened steel balls 24, in action in said race, receiving a coating of the mercury or amalfrom the body 23. The casting 22, is provided centrally from the underside with a recess 25, offset at 26, for respectively, re-

su-pporting in said recess and ofl'set portion balls 27, in bearing contact with preferably a chilled casting surface 28, supported on the base-plate 29, of the cast Around the base of the casting 22, is provided a circular projection forming a rib 30, and contacting with a circular ring 31, supported in a fixed position in the baseplate 29, of the casting 6. By the rotation of the pulley 17, on the shaft 16, from any suitable source of power, not shown, a gymtory action of the .ore crushing and grinding device 19, within the chamber 18, is efl'ected, to thereby cause ore matter falling by gravity through the throat of the hopper 10, 18, and hence into direct device 19, to be reduced1 to 15 charge into the path of action of the device 19, in a deflected .course by the outlet 32, over the gyra-ted series of balls 24, which by hundiing together and rotating in opposite directions to each other, in .action, in the dish-shaped casting 22,\efl"ect a rapid reduction of the .ore matter with its entrained values to bringthe same into substantially =1- powdered condition and at the same. time to assist the amalgamating body 23, to concentrate the values and to separate the powdered gangue from the values retained. As th rulings or gangue have no-aflinity for streams of air issuing through tubes 33, connected with a supcontact with the a socket 13, of an eccentrically ar-.

forced draft directed 3 current and forc pipes 37, from the ply pipe 34, from a suitable source, not shown, liberate the same, as will be presently more fullyexplained. The supply pipe 34, is supported from a cone-shaped hollow casting 35, forming the outer wall for the discl arge of fallin crushed matter from the ore crushing chamber 18, and also a conduit 36, with WhlCll is connected 3. series of outlet pipes 37, for freeing by suction the gangue or tailings from the recovered values of the ground ore matter. Suction is induced in the series of outlet pipes 37, by means of a through the injector pipes 38, and extending into the series of pipes 37, and each of wh1ch is provided with a regulatin cock 39, to control the extent of forced dra therethrough. In each of the outlet pipes 37, beyond the air admission pipes 38, is preferably provided an inverted cone-shaped partition 40, with a central opening, whereby suction in the said pipes 37, is made effective to lift the powdered gangue or tailings freed of values thereand away from the recovered through, values confined to the amalgam body 23, during the automatic continuous mechanical actions of the series of balls 24, in said body 23, of the casting 22, The gangue or tailings being taken then by the mducedair or sucked through the or into a suitable receptacle.

- into the In the apparatus as illustrated in Fig. 4, the pulverized ore is deposited in the ho per 10, and falls by gravity into the path of the gyratory series of balls 24, in the race of the casting 22, containing an amalgamating body 23. The gyratory action ofthe casting 22, in this form of the apparatus, is effected by means of the shaft 20, secured to the casting 22, and having a ball bearing 20, contacting with a series of balls 27, mounted in "the recess 40, of a standard 41. The opposite end of the shaft 20 is formed into spherical-shaped extremity 42, so as to engage a socket 43, of the eccentric crankarm 12, mounted on one end of a vertical shaft 11, supported in a bearing 11", from the standard 41, and carrying a driving pulley 17. The standard 41, supports a ring 31, with which it contact periodically, in the gyratory movements of the casting 22, with the rib 30, on the bottom of the casting '22. The air jets or streams issuing through the tubes 33, from the supply pipe 34, are admitted at suitable distances apart over the gyrated series of balls24, to lift ore matter freed of values, aided by the balls in the body 23, and by the suction action of the air induced through the conical space 37:, connectedwith the outlet pipe 37, and in ector pipe 38, in an outward direction,

opper 45-, of a tailings separator 46. This separator is rovided with a longitudinal chamber-47, having near the outapparatus, onto a dump let end thereof an inclined plane 48, and a downwardly inclined discharge spout 49. Through the center of the separator chamber- 47, is arranged a conveyer shaft 50, the series of blades 51, of which occupy sta gered relationship to each other 111 thelr continuous connected position on the said shaft and are adapted by the gyratory actions of the same in the body 23, of mercury or amalgam within the race'or channel 52, of the chamber 47, to cause not only a thorou h amalgamation of all traces of entrainef values of the gangue matter in the separator, but also by the series of blades of the conveyer a lifting of matter foreign l thereto, which is conducted over the inclined plane 48, and discharged through the spout 49, onto a dump or into a suitable receptacle therefor. It may be here remarked that in exceptional essary to use the tailings separator 46, as described, because in practice it has been .found'that after the pulverized ore matter vention as carrie out by the different types e recovered, has unof apparatus as explained, the ore matter is 9 not only thoroughly ulverized containing entrained values, but by the automatic continuous. series of operations, which the ore matter undergoes, is effected a complete amalgamation of the values with the of the mechanical means and amalgamating body having decided affinity for such matter, and none for the foreign matter; and moreover, without havin to handle the foreign matter durin the reeing of the same from entrained val ues of said ore matter. Having thus described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is 1. In an apparatus of the character described, a standard, a dish-shaped casting supported from-the standard for containing an amalgamating body and balls, a hopper located above said casting and having an outlet arranged to discharge pulverized matter directly into said casting, means for conducting a fluid or liquid with the pulverized matter into saidcasting and while the balls" are in action, a casting provided with a crushing chamber interposed between said ard for containing amamalgamating liquid instances only is it nec- 6 e series of progressive actions as 9 y as and for the purposes (IO-1.25

body and series of balls, a hopper with an outlet located above said casting, a second casting interposed between said 110 per and dish-shaped casting and suppor ted by said standard having a grinding or crushing chamber, a device, consisting of two truncated cones united and arranged base to base with the stems thereof connected re-- spectively, with said dish-shaped casting 10 and with means for gyrating both said deirice and dish-shaped casting substantially as and for the purposes described.

In witness whereof, I have hereunto set my signature in the presence of two subscribing witnesses.
