Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed March 1, 1906. Serial No. 303,586.

To all 'whom it may concern:

Bc it known that I, EMIL DEIs'rEu, citizen of theUnited States of America, and resi ent of Fort Wayne, inthe county of Allen "nd State of Indiana, have invented certain new and useful Improvements in Ore-Concentrating Tables, of which the following is a specification.

This invention relates to improvements in ore concentrating tables, and the object provide a table so proportioneil thereof is to Y and shaped, with means in connectlon therewith Which will direct the discharge of mineral therefrom as the same becomes clean;

and also to elect the movement of overlying gangue at a broad angle from that in which the underlying mineral moves.

My object 1s accomplished by the construction illustrated in the accompanying drawings in which .l

Figure i is a perspective view showing my improved concentrating table and the particular arrangement of iifiies thereon; Fig. 2

breast-board 3 sides. v lble is of suitable material, such as lmoleum,

is a plan view showing the rhomboidal form of the table, the relation of the driving mechanism in connection-therewith, and the arrangement of the'riiles; and Fig. 3 is a sectional view ofthe table in a vertical plane adjacentto aiijd parallel with the breast board, showing the` relative heights of the riifles.

Similar numerals of reference indicate corresponding parts in both views, and referring now to the same: 1' is a concentrating table of rilomhoidal form,`the length of which is approximately double that of its width, and which has a head-board 2 at one end and a. projecting along one of its 'lhe concentrating surface ofithe taand ranges in a fiat plane throughout, except at the outer edge of the table at a point immediatelyadjacent the head-board where the linoleuincover 4 is heldin a raised lposition by means of a wedge 5 which is inserted thereunder. A feed hox' is secured tothe head-board 2 and overhangs the surface of the table adj nt thereto.

It is the inte tion that the tableshall have differential recF .rocating movement in a line parallel with its ends, and suitable. driving mechanism fi is arranged in connection there.- with to impart thereto the desired lateral motion.

The table is suitably mounted by any well known means, and. when in proper position' M' In the operi for use ranges upon a decline from its endaat the head-board to its. opposite or tailings discharge end, and also upon lateral incline from the breastdioard side to its opposite or mineral discharge side. At the lower end of the table are arranged a tailings launder 8 `and middlings launder 9, and along the mine eral discharge side of the table, beneath the corresponding edge thereof, is arranged a mineral lauudcr l() to receive the discharged concentrates therefrom.

A particular feature ol' this invention is the form and arrangement of the table in connection with the )articular arrangement and character ofriflfcs ll thereon: The rifilcs are all relatively parallel and are arranged later- ,ally upon'thc table or parallel with theends thereof.

Each rilile tapers from its inner end at the breast-board to a thin edge at its outer end, but .the successive rillles, from vthe head-board to the tailings discharge end of the table, gradually decrease in height and project accordingly less from the correspomling surface of the table along the breast side thereof It will therefore appear that the projection of the rililcs at the u )pereud ofthe table is greater than those at t 1e tailings discharge' end thereof, except that the rillles taper to a uniform height at their outer ends. These riflles are arranged in succcssivefparallel series 12, 13, 14, and l5 respectively, the

end riflle 16 of cach series being of greater length than the other rllllesandextending to the mineral discharge edge" '17 of the table. The other riiilcs ofthe several series terminate u on the surface of the table at points suita )ly distant from the mineral dischuge'edge 17 and thereby are provided vlong unril'lied washing surfaces 18, each ofwhich is separated from the adjacent washing surface hy thc outer extensions of thel respective long rili'les 16. y,

tionof this invention the table is set in rapid'di'll'crential oscillating motion laterally, andlorc pulp fed intofthc feed box from whence 'it passes onto the 'ad jacent surface of theftahlc. Because ofthe longitudinal der-.line of the table, the pulp will move lengthwise thereon-to the lower end thereof,

and because of thev dilferential:motion and lateral-:incline of the table, together with the riliies'', the mineralq'qortion of the pulpfwill be direeted from beneath the pulp out upon the washing surfaces where it may be treated to the action of dressing 1lwater supplied in any suitable manner. The extending long riiiles directthe cleaned mineral from the correspending Washing surfaces to the mineral dis body of pulp as is commonly the case.

A feature of this invention is that the table is made rhomboidal and is actuated in a line parallel with its ends, and it shouldv appear that the lower en d of the table extends 'farther out in the direction of its motion than the upper' end thereof, so that the surface of the table ranges more or less in lin'e with the. tendency of movement of the body of pulp, viz: rl`lle pulp has a tendency to move at right angles to the line of motion be `anse of the longitudinal decline oi the table, and

to a more or less extent in liney with the motion of the table because of the differential action, and hence the movement ol pulp is somewhat diagonal tothe line. oi motion of the table. Another feature of this invention is the gradual decrease in the height of the successiveriiiles toward thel lower end of the table. The riiiles thus arranged.' have the effect of relieving the overlying gansrue so that the latter tends to move at a broad angle. toward the lower end of the table away from the washing surfaces. This eli'ects more perfect separation of the underlying mineral from the overlying ganguc than where the angle of movement between the urulerlying mineral and overlying gangue is less.

'lhe form and arrangement of the table proper herein set forth is similar to that shown in a previous application liled by me. lfeb. 19, 1906, Sr. No. 301,728, but is distinguished therefrom particularly by the arrangement of rifi'les. rihe table in the present instance is provided with riti'ies arH ranged especially for grades of pulp coarser than slimes.

Having described my invention, what l claim as new and desire to secure by Letters Patent is:

l. In a device of the class described, a reciprocatmg table having a projecting Thus scarse breast-beard at its reanside; and parallel riii'les upon thetable arranged in similar successive groi'ips, the end rilie of each group being of greater length than the other rililes and extending from the breast-board to the mineral discharge edge of the table," the other ritfiesbeing substantially of uni form lengtl'i, all of which commence their course at the breast-board and terminate at points suitably distant from the mineral discharge edge of the table, there being a washing surface along the mineral discharge edge adjacent cach group o'f rifiles, said 'ashing surfaces being separated -from one another b v the respective end rililes, all of said rillles being tapered toward their outer ends, there being a uniform decrease in the height of the respective riii'les at corresponding points successively toward the tailings discharge end of the table. 75

2. .ln a device of the class described, a recipro Iating table having a projecting ln'east-bmu'd along its rear sidej` and a series of parallel rililes arranged upon the table in similar kgroups7 the end rifle of each group 80 being of greater length than the other riffles and extending from the breast-board to the mineral discharge edge ol the table, the other rillles extending from the breast-board and terminating at ioints suitably distant from the mineral disdharge edge, there being a washing surface along the mineral discharge edge adjacent eaci group of ritiies, the washing.surfaces being separated from one another by the respective end riiiles.

Chin a device of the class described, a reciprocating table having a projecting ln'eastdioard along its rear side, and having also parallel riilles arranged in similar groups, the end rilile of each group extending from the ln'east-lmard to the mineral discharge edge of the table, and the other riilles extending vfrom the breast-board to points suitably distant from the mineral discharge ed e, there being a uniform decrease in the heig t of the respective riiiies at corresponding points successively toward the low end of the table. j

in testimony whereof I ailiX iny signature, in presence, of two witnesses.
