TE STATES FFIQEQ- PATENT ORE-CONCENTRATOR.
SPECIFICATION forming part of Letters Patent No. 352,578, dated November 16, 1886.
Application filed February 23, 1886. Serial No. 192,924.
To all whom it may concern:
Be it known that I, STEPHEN W. SHAW, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a. new and useful Ore-Concentrator, of which the following is a specification.
The object of my invention is to provide a machine whereby the precious and valuable metals contained in ores are separated from the gangue or debris and concentrated or gathered upon the center of a shaking disk and caused to pass through a screen into a receptacle beneath the disk ortable, while the gangue or debris is carried outward or backward in a reverse direction over the periphery of the disk ortable into a trough to be conducted away. I accomplish this object by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a crosssection of my ore-concentrator,taken through the middle of the disk or pan. Fig. 2 is a plan or top View of the same with a portion of the disk broken away. Fig. 3 is a view in detail of a section of the pan or disk. Fig. 4 is a horizontal section through the line mm, Fig. 1, showing the eccentric bearings for the pan.
In my machine for concentrating the precious metals or separating substances containing two or more elements, the one being heavier than the other, there is adisk, plate, or pan, A, say four feet in diameter, the upper side or face of which is preferably made slightly concave toward the center from the circumference or periphery thereofl To the edge of the disk is connected a downwardly-projecting lip or flange, B, to prevent the water from dripping off underneath the disk upon the gearing. A hole or opening is made in the center of the pan or disk, over which is placed a screen, C, of such a gage as to permit the concentrated .ore to pass through it as the particles accumulate at that point. Around the outside or periphery of the disk is placed a stationary annular trough, D, inclining to a certain point or depression, as at E, and over this trough the lip B, hereinbefore mentioned, projects. This trough receives all of the debris and water that is carried backward and over the edge (No model.)
or periphery of thepan or disk and conducts it off and out at the lowest depression.
- The feeding device of my machine consists of a screen and an annular shield, the one within the other, and bolted to the disk or pan.
At the center'of the screen is a plane surface,
as at F, while that portion surrounding the plane surface is perforated, as at Beneath this screen or receiver, and connected to it, is a shield, G, the center of which has an opening leading onto the top of the disk or pan of the same size or diameter as the plane surface F of the screen F so that as the pulp passes throughthe screen or meshes of the receiver it will fall down and strike upon the annular shield, and from thence pass from the edge of the opening onto the shaking disk beneath, and not fall directly upon the dischargescreen C.
This feeding device is bolted to the top of the disk through the medium of the standards or feet H and operates with it.
To the upper end of the driving-spindle I, which is provided with the 1niter-gear J, is secured a pin, K, eccentric to the vertical line -or axis of the spindle, which enters a seat or hole cast in the lug L, which carries the ore discharging spout M. From the sleeve or hearing which incloses the spindle I there extend four radial arms, N, which connect with the fourvertical posts, 0, bolted to the frame-work of the machine, and the upper ends of these posts are provided with shallow cups P, within which four pins connected to the bottom of the pan operate, and this gives play to the pan when it is set in motion, and thus it is always kept in a horizontal plane when motion is imparted to it. The miter-wheel J connects with the miter-wheel I and from the latter extends the horizontal shaft R, carrying the fast and loose pulleys S 8*.
The operation is as follows: The machine being set in motion by a belt-connection with the fast pulley on the shaft It, which imparts to the pan, through the intermediate mechanism above described, a vibratory or rotary re- 'ciprocating motion within and over the anshield. From thence it passes 0E the edge of the opening thereof upon the face of the pan, where the lighter or worthless portions-such as the sand and gangue-are carried over its peripheryinto the inclined stationary annular trough, while the heavier and valuable ore or sulphurets, by their greater specific gravity and the percussive and concussive force imparted to the pan, will sink through the agitated and lighter particles of pulp, come in contact with the surface of the pan, work their way centerward to the small screen 0, and pass through it into the inclined trough beneath and onto a proper receptacle.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
1. Inan ore-concentrator, the combination of a disk or pan having a slightly concave surface,and a central discharge-opening provided with a suitable screen,through which the heavier particles of ore pass, and means for imparting a vibratory or rotary reciprocating motion to said pan, substantially as shown and described.
2. In an ore-concentrator, the combination of a disk or pan having a slightly-concave su rface, and a central discharge-opening adapted to receive the heavier particles of ore which gravitate to the center thereof, and means for imparting a vibratory or rotary reciprocating motion to the pan, substantially as shown and described.
3. In an ore-concentrator, the combination, with the pan and means, as described, for operating the same, of a feeding device secured thereto, and consisting of a screen having a central plane surface, and a perforated outer surface and a shield below the screen, provided with a central opening, substantially as shown and described.
4. In an ore-concentrator, the combination of the disk or pan provided with a central lug having a seat or hole, and with four pins, with the spindle I, provided with a pin eccentric to its axial line, and the standards or posts provided with basins, in which the lugs or pins upon the bottom of the pan operate, as specified and shown.
In testimony that I claim the foregoing I have hereunto set my hand and seal.
