To all whom t may concern Be it known that ll, FREDERICK A. WiswnLL, a citizen' of the United States, residing at Oakland, in the county of Alameda and State of California, have invented cercharacter, so constructed that the grinding or pulverizing of. the ore containingthe precious metal, and the amalgamating of the metal, may be simultaneously performed.
A further object of the invention is to" provide a machine of theabove mentioned charactemthe elements of which are arranged in a highly conipactand convenient manner.
Other objects and advantagesof the invention will be apparent during the course of the following description.v v
lin the accompanying drawings forming a part of this speciiication and in which like numerals are employed to designate like parts throughout the same, Figure 1 is an end elevation of the apparatuaFig. 2 is a transverse sectional view takenon line 2-2` of Fig. 3, and, Fig. 3 -is a vertical longitudinal sectional view taken on line 3-3 of l`ig-1. 1-
lln the drawings, wherein' for the purpose of illustration is shown a preferred embodiment of my invention, the` numeral 10 -designates preferably horizontally arrangedrails or castings, constituting the foundation of the machine. These rails or castings are connected at their ends, vby preferably diagonally arranged braces 10', as shown. -Disposed between these rails or castings is` a `horizontal trough 11, having its upper end open to receiveA the lower portionof a re' volving drum, to be described. This troughv receives the pulp and water from the drum.
Journaled within these bearings are ',trans verse shafts 17 and 18, having flanged supporting -rolls 19 and 20, rigidly mounted thereon, respectively; The shaft 17 extends 'at one end outwardly beyond its bearing for te a substantial distance, ,and has a pulley 21 rigidly-mounted thereon, which'is adapted to receive rotation from a belt or the like. A pinion or gear 2l is also rigidly mounted upon this shaft. 4 Y
The numeral 22 designates a cylindrical casing or drum as a whole, which is'rotatably supported by the rolls 19and 20, in a manner to'oe described. This drum, as more 'clearlv shown inligs. 1 and 2, comprises an outer annular casing or ring 23, upon one end of which is formed an annular gear 24,' having an annular groove 25, disposed upon its inner side. This annular gear 2li meshes with the gear 2-1, as shown. vThe gear 24 carriesI an inwardly extending annular overliow flange 26, and a corresponding annular overflow flange 27 is arranged upon the opposite side of the outer casing 23, and secured thereto by means of bolts 28 or the like. DisposedV within the outer casing 23 is an inner protecting casing or lining 29, formed of hard steel or the like and held in place between shoulders 30, as shown. This protecting lining is rigidly secured to the `outer casing 23 for rotation therewith. As
As shown' in Fig..3, each of the annular- 'i a section Arranged within the drum v2.2, Ais a pulver-v izing or grinding roll 40 of'suitahlediameter to pass through either of" the rings 31. fi- This grinding roll has its periphery'protected by a hard steel annular.. casing or covering, 941, as shown: .The .casingr 141 is `vadapted to neo' contact 'with the" oreonthe-llikefedl between it and the.inner"lii`iing29 of the 'outer drum. The roll 40 is carriedl'by aftransverse' shaft .42, extending through?openings'. 43, 4formed in vertically vi'riovable v bearings on'- slides '214.
l-Tliese l openingsfft have "their lower ends open, y,as.;shown?:The bearings orl slides i/l .are verticallymovably' In0iinted'-"within-vertical guide's' .45., preferably formed integral ,wit-h" the horizontal-bars 12. Rigidly attached' "to thev upper'v endsi of the vertical' l guides-"l5 aretransver'se horizontal heads 46, having `screwthreaded.V openings to receive vertical adjusting screws A7, the lowerlends ioo of which have swiveled connection with the bearings or slides il. These adjusting screws t7 ai'e turned by hand wheels` 4S, rigidly attached to their upper ends, as shown. '.l`he bearings il ai'e normally .spaced a slight distance above the shaft 452, the weight of the grinding roll l0 being normali)v sullieieiit to crush or pulverize the ore. When the weight of this roll is not suflicieiit for this purpose, its crushing action inav be increased b v turning the hand wheels 4S in the proper direction, which turn the adjusting screws and through the medium of the hearingsl i force the roll el() to a -lower position in contact with the ore. v
' rlhe numeral 50 designates horizontal rails' which are bolted or rigidlyv secured to the heads le. Secured to corresponding ends of the rails 5t), are upstanding rodspl, to the upper ends of which are attached a hopper 52, l'for receiving suitably treated orel containing precious metal. Attached to the lower end of the. hopper 52 is a spoilt 53, the lower end of which is arranged to dischai'ge the material between the contacting faces of the inner roll and drum, as more clearly shown in Fig. 2l.
The numeral 5J; designates a water supply pipe. discharging the water upon the opposite side of the roll, las shown.
The operation of the apparatus is as follows: The drum Q2 is preferably driven clocliwise, asindicatedby the arrow in Fig. 3, such rotation being imparted thereto from the gear 2l. The ore containing the precious metal after suitable treatment, is fed into the hopper 52, and gravitates therefrom, in suitable amounts, through the spout 53, to be fed between the contacting faces of the grinding or crushing roll and drinn. Simultaneously with this 'supply of ore, a suitable amount of water is fed through the pipe 5l, to the opposite side of the roll. The pulp and water rise above the overfiow Hanges or members 2G and 27,and pass through the foraminous sections 3G. into the trough The large particles of the ore which have not been properly ground or pulverized, cannot pass through this foraininous material and are retained. within the drinn, until properly ground or pulverized. The small particles of precious metal, such as gold or the like, gravitate to the lower portion of the drinn and are retained therein by the overflow flanges or members. Should any of these tine particles of precious iuelal. pass with the, pulp and water to the trough ll, the)v will settle therein and ina)v he suhseiiuenllv removed and collected. llI do sii'ed, inercui-,v ina)v he ted into the drinn during the pulveriz'ii'ig operation, whereinv the ainalganuiting process will be practised substantiall)v simultaneously with the pul- \'eri'/,ing ol the ore. 'l`he niercur v having ay high specilic gravity' will he retained williiii the drum by the overllow flanges. 'l`lie lncrcur)v and ainalganiated precious metals ma)Y be removed lroin the driiiii bv any suitablel means, such as opening one ol the doors '35 and removing the saine by a suitable receptacle. lf desired, one of the overllow ilanges may be provided with an opening normally covered by a valve or the lilie, not shown.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the sinne, and that various changes in the shape, size, and arrangement of parts ma)v be resorted to without departing from the spirit of the invention or the scope of the subjoined claim. l
Having thus described the invention, I claim:
In a machine of the character i'lescribed; a supporting structure; supporting rolls carried thereby; a drinn arranged above and contacting with the supporting rolls, said drum comprising an annular outer casing having an annular gear formed upon one. end thereof and an inner annular overllow iiange formed upon the annular gear, said annular casing being provided near the, annular gear with an interior shoulder; a second annular ovcrllow tlange connected with the opposite end of the annular casing and arranged interiorly thereof to forni with the first named flange an annular recess; an annular protecting lining arranged within the annular recess and contacting with the shoulders of the recess; a grinding roll arranged within the drinn to eoperate with the annular protecting lining; and means to drive the, drum, embodying a gear engaging the anular gear.
