IMPROVEMENT IN CONCENTRATlNG-TABLES FOR ORES'.
Specification forming part of Letters Patent N 0. 177,1 74, dated May 9, 1.876 application filed January 22, 1876.
To all whom it may coiwcrn: 4
Be it known that I, J. UITOLLES, of Virginia .(Jity, in the county of Storey and State of Nehinged leaf arranged at the lower edge of the table; and ina rotating perforated pipe located above the table to deliver a sheet of water thereon, for the purpose of driving the collected particles into the receiving-box, as hereinafter described.
Figure 1 represents a perspective view of my machine; Fig. 2, a top plan view of the same; Fig. 3, a vertical cross-section of the same.
A represents a flat inclined table, provided with a surfacing, a, of cloth of any suitable kind,and with ledges b, to prevent the material t'rom passing over the ends. B represents a feed-box extending along the upper edge of the table, and provided in its front side with a row of discharge-openings, c, of the form shown, each narrowing down to a point at its lower end. 0 represents a receiving trou'gh or box extending along below the lower edge of the table. D represents a leaf or. board hinged to the rear side of the trough or box 0, in such manner that it may be turned under the edge of the table, to conduct the material therefrom into the box, as shown inFig. 2, or
turned back, as shown in Fig. l and in dotted lines in Fig. 2, so that the material passing over the edge of the table will bedischarged outside of the box. E represents a rotating tube suspended lengthwise above the upper edge of the table by endless belts d passing over pulleys 0, supported in the rigid frame The tube is provided from end to end with a row of perforations, g, and with a handlever, h, at one end, and is connected by a pipe, t, with a reservoir or pump deliveringlwater at a pressure corresponding to a head of from eight or twelve feet. 7
In operatingthe machine the feed-box B is partly filled with rough stones to insure an 'I can effect a rapid and th even distribution and a-steady flow of the material. to be treated, a steady and copious supply of water maintained in the box, and
the ore, sand, or tailin'gs introduced.therein.'
surfaceof the table, while the light refuse particles are carried over the lower edge and discharged outside of the box 0.
After the collection of a suitable amount of metal upon the table, the supply of water to the feed-box is stopped, the leaf D turned under the edge of the table and water supplied to the pipe or tube E, by which it is delivered through the perforations upon the table in a row of fine jets forming an almost continuous sheet or film.
By means of the leverh the pipe or tube E is rotated, and the sheet of water swept over the table from top to bottom, soas to drive all adhering particles therefrom and Wash them down into the collecting-box C. After this operation the jets are stopped, the leaf, turned out, and the feed-water again started. By employing the cloth surface, giving the table the proper inclination, andproperly regulating the flow of water, I find that ough separation without agitating the table, and without the employment of manual labor foran y other purpose than that of feeding the material; and by the employment of the fixed table with its cloth surfacel can separate particles which cannot be retained-in machines which vibrate." By the use of the feed-openings 0 of the form shown, I render the discharge of the sand ore or other fine material very steady and gradual,
as it will be carried through the narrow portion of the openings while the lighter water will pass over the same, through the upper large end of'the openings, taking up the material gradually and distributing it evenly upon the table.\ It is obvious that the rotating tube may be sustained in any other suitable manner, and that it may be connected in any suitable manner with the source of watersupply.
The object in arranging the perforated pipe Free.
so that it can rotate is to permit a gradual change in the direction of the jets, so that.
their point of impact upon the table can be advanced from its upper to its lower edge, and thereby every portion" of the surface subjected in turn to the direct impact of the jets, in order to effectually loosen and drive forward the particles therefrom;
Having described my invention, what I claim is-- 1. In a concentrator, the combination of a stationary inclined flat table, A, provided with a olothfacing and a stationary feed-box, provided with pertbrations,,and arranged to deliver the ore and water upon the table, as shown and described.
2. The feed-box B, pro 'ided with the discharge openings 0, of decreasing width toward their lower ends, as shown.
3. In combination with the inclined concentrator-table A, the collecting-box O and hinged leaf D, as and for the purpose described.
4. In combination with the concentratortable A, the rotating perforated tube E, substantially as and for the purpose described.
' a 5. The feed-box B, providedwith the openstones, as and for the purpose described. 6. The combination of the inclined clothtating perforated pipe E. 1
