SPECIFICATION forming part of Letters'Patent No. 324,783, dated August 18, 1885.

Application led June 12, 1885. (No model.)

To all whom it may concern:

Beit known that I, LEONARD S. OsGooD, a citizen of the United States, and a resident of Stockton, Tooele county, Utah Territory, have invented certain Improvements in Ore-Concentrating Tables, of which the following is a specication.

My invention relates to that class of con. centrating-tables used for saving gold, silver, lead, and othernietals and minerals; and the object is to provide a concentrator that will save the very iine flour gold, silver, lead, or other mineral that is usually lost by the ordinary machines and methods employed and in common use at this time.

In the drawings which serve to illustrate my invention, Figure l is a side elevation of my improved concentrating-table. Fig. 2 is a plan of the same, the central portion being broken away. Fig. 3 is a transverse section taken on line 3 3 in Fig. l.

A is a suitable stout frame, in which is hinged at a a stout frame, B, which has a vertical swinging movement on its hinges at a. The free swinging end of frame B is supported on a screw, C, which is coupled to the frame B by a hingebolt, b, and fits `at its lower end in a socket in a plate, c, on the main frame. On the screw C is a wheel-nut, D, whereby the l'free end of the frame B may be raised and lowered and adjusted with the greatest nicety. On the frame B are mounted rollers d d, the axes of which rest in open bearings in pillowblocks e e on frame B. These rollers have circumferential grooves in theirperipheries in the manner of sheaves.

E is the concentrating-table proper, which is mounted on the rollers d, and is made capa# ble of receiving an endwise reciprocating movement. On the bottom of this table are Vshaped tracks gg, the edges of which engage the grooves in the rollers d. This ilange construction is designed to prevent any lateral movement of the table on the rollers. The table E has its upper surface covered with a metal plate, x, the kind of metal being that best suited to the ore treated. At the sides of the table are raised rails or anges ML, and there is also a raised rail or flange, h', at the receiving end.

The mechanism for imparting a reciprocat ing movement to the table comprises a rotatively-mounted shaft, F, and its pulley G, an eccentric, t', on this shaft, and an eccentric-rod, j, leading from the eccentric strap t" to the end of the bed and connected thereto with ahingecoupling. Rotation of shaft F will produce reciprocation of the bed, and the extent of this reciprocatory movement may be varied by making the throw of the eccentric adj ust able in any of the well-known ways.

The ore,in pulpy orliquid form,is fed onto the table at the end opposite to the hinge a through a cross-pipe, 7a, provided with perforations or short jet-pipesZZ. Any other equivalent means may be employed for delivering the ore on the table. I-I is an apron secured at its upper end to that end of the table opposite the feed. The refuse ilows down this apron.

In using my machine the table is given the proper vertical adjustment. The [ine ore, sand, or slums77 is fed onto the table, as described, and the table reciprocated, in order to cause all the iine particles to settle to the bottom. The refuse is caused to ow off at the apron H, and the valuable product left adhering to the surface is shoveled off into any suitable receptacle for future reduction. Another charge of slums, &c., may then be run onto the table and the process repeated.

The motion of the table is suoli that the refuse matter is carried off by the water and the heavier valuable product retained on the table. In treating gold-bearing material the plate .fr on the table should be of copper,which would permit of its being amalgamated, whereby it would catch all the gold, silver, or amalgam, (as in the case of slums.) When a sufficient amount had been collected, the plate would have to be cleaned off and the process repeated.

Having thus described my invention, I claim* A l. The combination, with the concentratingtable and the means, substantially as described, of imparting to it a reciprocating motion, of the hinged supporting-frame I3, provided with a nut and screw for adjusting vertically its free end, the grooved bearingrollers d, and the tracks g, substantially as set forth.
