SPECIFICATION forming part of Letters Patent No. 632,075, dated August 29, 1899.

Application filed- .Tune 6, 1898. Serial No. 682,711. (No model.)

To all whom it may concern.-

Be it known that we, JOHN G. lVATERs and RICHARD O. WATERs, of Romley, in the county of Ohaffee and State of Colorado, have invented a new and Improved Concentrator, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved concentrator more especially designed for treating the pulp from stamp-mills or the like, the concentrator being simple and durable in construction and arranged to insure a complete separation of the precious metals from the barren sand or gangue known as tailings.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improvement. Fig. 2 is a front elevation of the same with parts in section. Fig. 3 is a transverse section of the same on the line 3 3 of Fig. 1; and Fig. 4. is a side view of the means for driving the table, the view having some parts in elevation and also other parts in section, such other parts being sectioned slightly to one side of the line 4 at of Fig. l.

The improved concentrator is provided with a table A, covered with copper or other suitable covering and made segmental in shape, preferably semicircular, as illustrated in'Fig. l, the table being inclined from the outer peripheral end in a downward direction toward the inner end, as will be readily understood by reference to Fig. 3. The table A is supported at its outer end by legs B, having their upper rounded ends set in similarly-shaped sockets A, secured to or formed on the under side of the table A. The lower rounded ends of the legs B are set in similarly-shaped cups B, held on screw-rods B screwing in nuts B secured to the floor or other suitable foundation, the screw-rod being adapted to be locked in place after the desired adj ustment is made by a jam-nut 13*. Thus by the arrangement described the several legs B can be readily raised or lowered to give the desired inclination to the table, and at the same time the legs B permit an oscillation of the table, as hereinafter more fully described.

The inner end of the table A is provided on diametrically opposite sides with metallic arms A A engaging screw-rods O 0, respec tively, carried by a head D, mounted to turn on a pivot E, carried by a post F, secured to the floor or other foundation,the center of the pivot forming the center for the segmen tal table A. Nuts 0 screw on the screw-rods O C to hold the arms in place on the screwrods, the nuts permitting of adjusting the arms at different heights, if desired, and as indicated in Fig. 2that is, adjusting the arm A lower than the arm A so that the lefthand side of the table is less in height than the right-hand side of said table.

The head D rests on a shoulder E on the pivot E, and the latter is formed at its lower end with a threaded part E screwing in the post F to permit of raising or lowering the head D, and consequently the inner end of the table, to give the latter the desired inclination according to the material under treatment. The upper end E of the pivot E is made polygonal for the application of a wrench or other tool to permit of conveniently screwing the pivot up or down in the post F for the purpose above mentioned.

The head D is provided with a transverselyextending arm D, (see Fig. 3,) on which is bolted one end of a bar G, secured to the under side of the table A at the middle thereof, said bar being formed at its outer end with a slotted head G, engaged at opposite ends by nuts H screwing on the threaded ends of a rod H, forming part of the device H for imparting a jolting reciprocating movement to the table A, as hereinafter more fully described. The end of the rod H is provided with a frictionroller H in contact with the peripheral surface of a cam H, secured on a shaft H carrying fixed and loose pulleys H, connected by belt with other machinery for imparting On the coiled on the rod H and presses with one end against a collar H", held on the said rod, and

with the other end against a part of the frame 11 supporting the actuating device. The spring 11 serves to hold the friction-roller H at all times in frictional contact with the peripheral surface of the cam 11, so that when the shaft H is rotated the said cam H imparts a quick impulse forward and backward to the rod H, and consequently to the table A, without rest between the two movements, a rest then taking place between two impulses, as will be readily understood by reference to the shape of the cam H as shown in Fig. at.

The outer end of the table A is provided with an upwardly-extending flange A for preventing the Water and pulp discharged at this portion of the table from flowing over the upper edge thereof, the pulp and water being delivered to the table by a segmental pulp and water distributing trough I, hung on clips I, vertically adjustable in standards 1 secured to the floor or other foundation. The trough I is formed with spaced apertures, as is plainly indicated in Figs. 1 and 3, and one side of the trough is extended to discharge the pulp and water toward the flange A, as will be readily understood by reference to Fig. 3. In the middle of the trough I is held a partition I for keeping the pulp and the water separate, the pulp being discharged through a pipe J into the left-hand end of the trough while the water is passed through a supply-pipe K into the right-hand end of said trough. The pipe K is provided with a valve K for controlling the flow of the water through the pipe to the right-hand portion of the trough.

The right hand or concentrate discharge side of the table A is open, a gage L being held adjustably on this side of the table by a clip L for increasing or diminishing the discharge-opening for the con centrates at this side of the table.

The inner end of the table A is provided with a ridge or flange A over which the tailings pass into a discharge-trough N, provided with a downwardly-extending pipe N, open- 1 ing into the funnel O of the pipe 0 for carrying the tailings to one side of the machine.

The operation is as follows: WVhen the table is intermittently oscillated by the device H, as above described, and the pulp is fed onto the left-hand side of the table and the water on the opposite side thereof, then the quick forward and backward impulse given to the table causes the concentrates to travel over the table in the direction of the arrow at, (shown in Fig. 1,) and during the resting period of the table the concentrates have sufficient time to settle for the next thrust, as described, so that a rapid travel of the concentrates over the inclined table takes place, the concentrates finally passing from the table at the right-hand side thereof between the gage L and flange A. The tailings readily separate from the concentrates on the jolting motion of the table, it being understood that owing to the position of the distributor the heavier portion of the pulp passes onto the table at or near the left side, while the lighter part of the pulp passes onto the table toward the middle thereof, so that the lighter portion first comes in contact with the water and is readily washed downward over the head A into the trough N to be discharged into the pipe 0, leading the tailings from the machine. The concentrates on reaching the table commence to travel in the direction of the arrow at and are subjected to the action of the water as they pass on their journey over the table, so that all tailings, sand, (530., are effectively washed out of the concentrates and separated therefrom before theconcentrates reach the right-hand or discharge side of the table.

Having thus fully described our invention, we claim as new and desire to secure 'by Letters Patent- 1. In a concentrator, the combination of a table, a vertical post on which the table is mounted to swing, the table having a segmental form and having a flange at one end, the other end of the table being adapted to discharge the concentrates, a gage mounted at said other end of the table to regulate the discharge thereat, means for supporting the outer portions of the table so as to permit the movement thereof, and a curved trough extending around one edge of the table adjacent to the post, to receive the tailings.

2. In a concentrator, the combination of a post, a segmental table mounted to move on the post, the post being located at the inner edge of the table, means for supporting the outer edge of the table so as to permit the movement thereof, a trough extending around the inner edge of the table and adapted for the discharge of the tailings, a flange secured to one edge of the table at one side of the trough, the opposite edge of the table being adapted for the discharge of the concentrates, a gage mounted at said opposite edge to control the discharge thereat, a second and curved trough located above the outer edge of the table and discharging therefrom, and a partition situated in said trough, to divide the same.

3. In a concentrator, the combination of a post, a vertical pivot mounted thereon, a head mounted to turn on. the pivot, two arms attached to the head and extending in opposite directions therefrom and being provided with means for adjusting their relative height, a third arm also attached to the head and projecting between the two first-named arms, a segmental table supported on the three arms, means for supporting the outer edge of the table to permit the movement thereof,a curved trough located at the inner edge of the table adjacent to the post, a flange located at an edge of the table adjacent to the trough, the opposite edge of the table being adapted to discharge the concentrates, and a second curved trough located above the table at the outer edge thereof and. serving to discharge mit the movement thereof, a curved trough secured at the inner edge of the table adjacent to the pivot, and a flange at one edge of 15 the table adjacent to the trough, the opposite edge of the table being adapted to discharge the concentrates, and the curved trough being adapted to receive the railings.
