coNcEnTeA-rine APPARATUS.

SPECFlUAlON forming part of Letters Patent No. 669,043, dated February 26, -1901.

Application led August 20, 1900. Serial No.27y363. (No model.)

To all whom, it may concern:

Be it known that I, ADOLPH K. CROSS, a citizen of Germany, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvementsin Ooncentrating Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in apparatus for saving` the metallic values of pulverized ore or placer material by concentration; and to this end theinvention consists of the features, arrangements, and combinations hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure lis a vertical longitudinal section taken on the line as Fig. 2. Fig. 2 is an end elevation of the apparatus viewed from a position at the left of Fig. l. Fig. 3 is a perspective view of myimproved concentrating-screen.

The same reference characters indicate the same parts in all the views.

Let the n umeral 5 designate a suitable frame upon which is swung a trough or sluice 6. To the sides GfL of this trough .are connected the lower extremities of depending rods or hangers 7, whose upper extremities are movably connected with the frame. The arrangement of the rods '7 is such as to permit a lateral oscillation of the trough through the instrumentality of suitable mechanism. As shown in the drawings, a crank-shaft 8 is journaled to one side of the frame, and rods 9 lead from cranks of this shaft to the trough, the arrangement being such that as the crankshaft is rotated an oscillating movement is imparted to the trough in a direction at right angles to its length. The trough is so hung as to give it a suitable inclination, its head or right-hand extremity (see Fig. l) being highest. Near the lower extremity or tail of the trough an opening 6C is formed in its bottom. In the rear of this opening is placed a part 6, which is oppositely inclined from the upper portion of the troughs bottom. Suitably supported in this trough is a screen l0, composed of flat longitudinal strips 10a, interwoven with transverse strips, wires, or rods 10c. The strips lOa are placed in contact with each other, while the transverse strips or wires l()c are placed some distance apart. In forming the screen any two adjacent strips l0 are passed the one above and the other below the same transverse wire, while each strip 10 is passed alternately above and below the transverse wires. Hence cells or depressions l0d are formed in the alternate strips 10iL on the line of any wire 10c. These cells have side openings, but no vertical outlet, since the strips l0 are close together. As shown in the drawings, the cross-wires l()c are fastened by bending their eXtremities to form hooks 10g, which engage the outer edges of the outer strips 10a. This screen, as shown in the drawings, forms a concentrating-table which is supported by cleats 6g, attached to the opposite sides of the table. Only one of these cleats is shown in the drawings.

Vhen the apparatus is in use, the material to be treated is fed in the form of pulp upon the upper extremity of the screen-table from a hopper l2 (see dotted lines, Fig. l) or in any other suitable manner, while a lateral oscillation or vibrator-y movement is imparted to the trough or sluice at right angles to the direction of the strips l0 ot' the table. Under the influence of this movement the metallic values are caused to settle in the cells 10d of the table, while the gangue is carried downwardly by the water and discharged at the tail of the table. The finer concentrates pass through the side openings of the cells l0d and thence into the bottom of the trough or sluice, from which they are discharged IOO jacent side edges in Contact, and separated In testimony whereof I affix my signature -transverse Wires or rods with which the said in presence of tWo Witnesses. strips are interwoven to form cells having side openings, but no vertical outlet, and means for imparting a Vibratory movement Witnesses: to the table at right angles to the length of DORA C.
