UNITED STATESA PATENT OFFICE.
GUSTAVE A. GELIEN, OF SAN FRANCISCO, CALIFORNIA.
ORE-GRINDER.
SPECIFICATION forming part of Letters Patent No. 508,008, dated November '7, 1893.
` Application filed November 1, 189,2. Serial No. 450169.2- (NO DlUdBl- T all whom it may concern.-
Beit known that I, GUsTAvE A. GELIEN, a
` citizen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Ore-Grinders, of which the following is a specication.
My invention consists in certain improvements in ore grinders which will first be fully described with reference to the accompanying drawings, and then pointed out in the claims.
In said drawingsz-Figure l is a view'in vertical section of my ore grinder. Fig. 2 is a plan or top view of the same. Fig. 3 is a View in detail of the device for raising and lowering the grinding shoes. Fig. 4 is a plan or top View of the ore-feeder or hopper.
A represents a tub or tank composed of wooden staves setlnon end as shown and suitably bound together by hoops and bolts and resting upon frame-work or timbers B, B. The staves composing the tub are made of considerable thickness at the base and inoline downwardly and inwardly as at BX, so as to impart strength to the tub and give lateral support to the outward pitch or inclination of the rim B? of the pan. By thus constructing the periphery or rim of the pan, the stone mullers can be more easily lifted and will not stick or adhere so closely to the rim as when made in a true perpendicular line.
On the bottom of the tub are placed the l metal-plates or dies C, C, which constitute the grinding surface of the machine. They are laid in sections so that they can be removed from time to time when worn and are Lcontained within the area of the two rim-plates D, D by which an annular grinding-trough is formed and sufficient annular space in the center of the machine is had for the operat ing mechanism. By this construction of pan the ore under treatment is confined in the narrow` annular trough around the axis of revolution and consequently a more rapid reductionfis had with less expenditure of power than where the ore isallowed to spread over a greater area or reducing surface. The inner rim-plate D is flanged as at D2 and bolted to the iloor or bottom of the tub and the outer rim plate D is made to fitclosely against the side of the tub while the edge will rest vupon the iioor and afford aclean space between the two rims for laying the plates or dies and forming the annular grinding floor or trough which is laid in sections meeting as at DSDS.
These rim-plates may be cast Whole or in sections properly supported and sustained when laid. v
The grinders or mullers E F.X F FX are composed of stone, and any rock of a sufficient hardness and that will not Wear away too rapidly will answer for the purpose. Four of these mullers or grinders are employed and thereby engage with the ore in the pan and reduce it to the desired degree of neness for amalgamation in the presence of quioksilver in the usual Way. The grinders E E are of irregular shape and their outer edges are made rounding to engage with the circular rim of the pan as well as with the bottom oor or dies, and are located diametrically opposite each other. The grinders represented at F F are quadrilateral in form and move around the inner rim of the pan also diametricallyopposite each other.
Both series connect with the four arms G, G, GX GrX of a turn table or plateH by means the grinders E F. and 3, 3, and 4, 4, of the .grinders AF F the two latter grinders or mullers being pivoted to turn table H by the straps I, I, by which they are held in a diagonal-position to the axial line of the machine, and their inwardly beveled front ends f will tend to draw` the pulp away from the periphery of the pan toward the inner rim and to the grinding faces of these inner mullers.
As a further means of directing the pulp away from the face of the inner rim of vthe pan and cause it to pass more completely under the grinders two diagonal wings or scrapers J, J, are connected to the arms G G of the turn-table the beveled points j of which follow in the rear of the grinders or mullers F, F and in close proximity with the innerrim of the pan. They are raised or lowered by the levers I', I', pivoted at I* IX connecting with the scrapers by links l2 I2 and by rods I3 I3 which in turn connect with the collars I4 I4 upon the driving shaft of the machine. From the collars extend the operating hand levers I5 I5 pivoted at I6 I6 having forked ends 17 17 which engage with collars I4 I4 and by raised or depressed, the collars moving up or down on a feather of the shaft and the position of the scrapers is maintained by the hand levers engaging the teeth on the rack J x. Each of the four arms of the turn-table carrying the mullers or grinders is provided with a stay rod K, K, K, K, which rods connect with a collar K through which the driving shaft of the machine passes and to which it is keyed.
In order to raise up the forward ends of the mullers or grinders E EX a sufficient distance from the dies so that the pulp will pass under and come in contact with the grinding faces I have provided levers or gates L LX which are pivoted between their ends to ears l rising from supplemental arms g of the turntable and extend outward in a diagonal manner and connect with the mullers by the eye bolts and links L2 L2. These levers are opf erated in the same manner as the levers which connect with the Scrapers, that is to say by the rods L3 L3, collars L4 L4, levers Ls L8, and to the'ends of the levers and rods is connected a cord or Wire cable L6 working in a sheave or grooved pulley L and by operating the levers Ls Ls of the series the ends of the mullers or grinders are raised or lowered at will. By this construction and arrangement of grinders or mullers and wings or scrapers there will be little if any vortex of the pulp contained in the pan even though the pan be revolved at a rapid rate.
An ore feeding device consisting of a double funnel shaped hopper M is keyed to the driving shaft above the operating gate or lever. The bottom of this hopper is made inclining from diametrically opposite points M MX to diametrically opposite discharge openings M2 M2 so that the ore will gravitate to- Ward the lowest depressions in the bottomthe discharging points, and from thence `fall to the grinding pan; and for this purpose a` hose pipe may be connected to the discharge openings for conducting the ore without splashing to the pan beneath. It will thus be seen that all the supporting and working parts of the machine are geared or keyed to the shaft the lower end of which passes through the bottom of the tub and is stepped on a cross timber of the supporting frame. The shaft is driven by the miter gears N, N, from a pulley N X at the end of a horizontal shaft N2 at a speed of about forty revolutions per minute. The oreis first crushed to about the size of peas and is fed along with water to the machine by a spout connecting with the hopper (not shown) and the reduction of the ore is known as wet reduction. As amalgamation takes place in a separate machine the reduced ore is taken from my grinding pan through a suitable discharge opening O.
Having thus described my invention, what Iclaim, and desire to secure by Letters Patent, is-,
1. The combination in a grinding machine of the character described, with an annular pan, an upright shaft in the center of said pan, radial arms carried by said shaft, and supplemental arms also carried thereby; of mullers within the pan, links connecting them with said arms, levers pivoted between their ends to ears on said supplemental arms and connected at their outer ends to said mullers, and means for depressing the inner ends of said levers at will, as and for the purpose set forth.
