SPECIFICATION forming part of Letters-Patent No. 761,259, dated May 31, 1904.

Application filed September 5, 1903. $erial No; 172,168. (No model.) V

To all whom it may concern:

Be it known that I, PHILIP H. SHUE, a citizen of the United States, residing in the city and county of Denver and State of Colorado,

that they 'will remain in suspension for a brief time in the water composing the pulp. I The Object of the invention is to produce an improved device for the purpose stated char- 1 acterized particularly by the combination of a shaking-table in which the stratification of the pulp is effected under water and by gentle agitation, so that the particles'settle in water according to their specific gravity, and from which the heavier particles are conveyed by a belt to a stationary bath in which said particles are Washed from the belt and deposited. Improvement is also claimed with respect to the means for hanging and shaking thetable I and for driving the belt.

The invention further embodies the use of an aimalgamating-plate carried by the shakingtab e. r

The table embodied in the invention reciprocates sidewise, and the belt travels lengthwisearound the same, which has the effect of stratifying the pulp and also throwing the heavier pulp near the sides of the table, where it may be more readily removed, and the higher gravity particles composing the pulp may be permitted to set or adhere to the belt and be removed by its motion. Provision is made to draw off the tailings from. the table and also to draw oif intermediate values, if desired.

Further advantages of construction and operation will, it is believed, be apparent from the following description and the drawings.

In the drawings, Figure 1 is a side elevation of the apparatus. Fig. '2 is an end elevation thereof. Fig. 3 is avertical longitudinal section. Fig. 4 is a vertical cross-section. Fig. 5 is a detail in elevation of one of the hangers or beams from which the table is suspended, and Fig. 6 is an elevation of the table alone.

Referring specifically to the drawings, the main frame of the apparatus is formed of sills 6, uprights 7, and cross-pieces 8 at the top thereof; suitablyv braced, as by tie-rods 9, to stand the vibration. The table proper comprises sides 10 and an inclined or troughshaped floor 11, and at one end the sides are extended upwardly to support an amalgamating-plate P, which descends in a series of steps from the end of the table to a point at the water-level a: just above the lowest part of the floor of the table. The floor of the table forms a trough into which, the pulp is discharged from the amalgamating-plate. At A, A, and A are indicated rollers, over which the belt B passes around the floor of the table. One of said rollers is located at each end of the floor, and the other roller depends below the sides of the table to carry the belt into the bath or wash-water contained in the trough 0, supported on the sills of the frame. The upper run of the belt passes over the floor of the table, around the rollers at the ends thereof, and under a roller D, positioned just above and close to the lowest point of the floor, causing the belt to travel through the pulp and water and adjacent to the lowest point of the floor, traveling in general direction contrary to the flow of water, which is toward the tailings-discharge opening d in the side of the table. The table is hung by hangers H and rods 12 from a shaft E, supported in bearing-boxes upon the cross-pieces 8 of. the frame. The hangers rock or swing on the shaft, the rods being of suflicient length to' make the variation of the table from the horizontal during the vibration thereof negligible.

The table is vibrated by means of a shaft F,

having at the end thereof an eccentric O, connected by a rod to a beam h, extending between the sides of the table under the floor thereof. a The shaftF finds its bearings in suitable boxes on the main frame. I

The belt B is driven by the roller A, one end of the shaft of which carries the sprocket S, connected to sprocket S by chain 8. The shaft 8' of the sprocket S is carried in bearings formed in arms y, projecting from one of the hangers H, and said shaft carries on its inner end the gear W, in mesh with the worm WV on the shaft E. By this arrangement the gearing for driving the belt-roller is carried by the same hanger as the table and remains concentric therewith during its vibration, so that the chain and other parts of the gearing are retained in proper relation and alinement.

The bearing-pieces 12 for the shafts of the rollers A, A, A and D are adjustable by a slot-and-bolt construction to tighten and adjust the belt and to vary the distance of the roller D, and consequently the belt, from the bottom or lowest point of the floor of the table.

At a an opening is indicated to draw off intermediate values, and the flowtherefrom may be regulated by cock Z.

At 13 are indicated wooden spring-pieces,

which are attached at each end to the upright 7 of the frame and bear at or near the middle against the sides 10, to which they are securely fastened by bolt 5, extending through both springs and the beam h, thereby producing a spring-cushion to secure a steady vibration without jar or violence, thus preventing undue strain on the parts, as well as economizing power necessary to vibrate the table. The springs are in equilibrium,-so that when the table is at the center of vibration neither is in tension; but any movement either way puts both in tension, producing a smooth vibration without the jar incident to bumping tables.

In operation the table is shaken by the shaft F and its connections, and in practice I have found about one hundred and forty-five to one hundred and sixty revolutions per minute about right for the usual pulp. By rotating the shaft Emotion is given to the belt B. This motion is preferably imparted from a suitable pulley f on shaft F by means of a belt to a corresponding pulley on the shaft E. These pulleys are preferably cone or changespeed, so that shaftE andbelt B may be adjusted to any required rate of speed. The pulp is fed to the upper end of amalgamating-plate P, and it is to be-noted that this is made with successive shallow steps, so as to secure an inequality of rate of flow over this plate. The pouring from one step to the other will carry the heavy particles of the pulp near to the crest of the next step, thereby preventing any stratification or setting upon the plate and leaving its surface free to come in contact with every part of the pulp passing over it. Some of the metal is thus got by the amalgamating-plate. The lower end of this plate is turned up, forming a trough p, into which any quicksilver or amalgam loosened from the plate while in operation. is deposited. This trough may be kept free from being filled with the deposit of the heavier gravity particles by the use of a stationary brush 9', contained within this trough and attached to the frame 7, whereby the vibration of the table will serve to prevent any setting within it, thereby affording asafe lodgment for any quicksilver or amalgam unintentionally escaping. From the lower end of the plate the pulp flows into the water on the table, and by the oscillation thereof all but the heaviest particles are kept in agitation, and finally flow out either through the discharge 0! for the'tailings or the spout a for the intermediate values. The heaviest particles settle and set on the canvas belt B and by the continuous motion thereof are carried around the rollers A A into the water in the trough C. .This trough is stationary, and inasmuch as the belt vibrates laterally with the table the particles are washed off the belt by the movement thereof in the water and settle in said trough, whence they may be removed inany suitable manner.

It will be noticed that the movement and vibration of the pulp over the amalgamatingplate insures that all the particles of free metal will come in contact with and be gathered thereby. Also thepulp is held in suspension and agitation in a considerable depth of water on the table, permitting the stratification' thereof, so that at least three gravities may be separated, and finally the continuous belt vibrating with the table and passing through the heaviest particles at the bottom of the floor thereof and afterward through a stationary bath provides a. convenient and successful means for removing and collecting the greater values.

What I claim as new, and desire to secure by Letters Patent, is i 1.'The combination With a trough-shaped table vibrating laterally and adapted to contain Water, of a traveling belt passing over and around the table lengthwise and at an angle into and out of the water therein, and a wash-trough under the table, through which the belt passes.

2. Thecombination with a trough-shaped table vibrating laterally and adapted to -contain water, of a traveling belt which vibrates with the table and travels over and under the same and at inclines through the Water therein, and means to Wash the belt.

3. The combination with a trough-shaped table vibrating laterally, the inclines of the bottom of which extend lengthwise, of a traveling collecting belt passing lengthwise around the table and adjacent the bottom thereof at the lowest part, and means to remove ore particles from the belt.

4. In a shaking-separator, in combination, a vibrating trough-shaped'table, adapted to contain Water and having a submerged roller in the lower part thereof, a traveling belt passing around the table and under said roller, adjacent the bottom of the trough, and means to remove particles from the belt, outside the trough.

5; In a separator, the combination with a shaft, of a table hung therefrom and vibrating laterally, and a belt traveling around the table and having driving connections with the shaft.

6. In a separator, the combination with a shaft, of a table hung therefrom and oscillating concentrically therewith, a roller carried by the table and having driving connections with the shaft, and a belt passing around the roller and over the table.

7. In a shaking-separator, in combination, a table vibrating laterally and having a separating-trough adapted to contain liquid, a

submerged roller within the trough at the deepest part thereof, a belt carried by the table and passing under the roller, in proximity to the bottom of the trough, and a sta tionary wash-trough under the table, through which the belt passes.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
