Application filed April 2, 1881. NA model.)
To all whom tt may concern.-
Be it known that we, AMBROSE BLATGHLY and GUIDO KUSTEL, of the city and county reference being had to the accompanying draw- Ourinvention relates to an improved machine for separating the heavy and valuable particles from the light and worthless portion of ore-pulp, sand, and anriferous earth, and at the same time concentrating the heavy particles in a body, so that they can be treated by any of the known gold-saving methods without handling the barren and worthless material.
The objects of the invention are to provide a machine of the above-mentionedcharacter that will perfectly and effectually separate the particles passing over the surface of the tables, and providing the latter with means for separating the pulp or other anriferous' material intothree or more grades, and, further, sepa rating and'concentratin g the middlin gs or seeond-grade particles. These objects we attain by the construction substantially as shown in the drawings and hereinafter described.
Referring to the accompanying drawings, Figure 1 showsan elevation and longitudinal section. Fig. 2 shows a plan view with the, upper set of tables. Fig. 3 shows an end view with a pair of tables. Figs. 4 and 5 are detail views of the hanger from which the tables are suspended. Figs. 6 and 7 are longitudinal sections, showing details of the tables. A represents any suitable frame-work, having oross-timbersb b, from which the inclined .tables (J O are suspended. The frame is wide Each table is suspended by rods 0r hangers d atieach corner, so that the suspension of each table is independent of the other. We have represented three pairs of inclined tables sus-- pended one above the other; but a single pair could be used. The construction of each ta- 5o ble and the arrangement of the pairsare the of the construction;
same, so that we will only describe a single palr.
To provide a bed or table that will not warp or become distorted, we construct each one inthe following manner: We make the bottom of each table of a number of narrow and separate strips of wood laid'closely together, and arranged in two layers, one layer running longitudinally and the other transversely, so that the grain of one layer crosses that of the other. A wooden pin or metallic nail or screw-is then inserted through the center of each cross-layer to secure and bind the strips firmly-together. Oross-stripsjj on the bottom and along the sides and ends serve to give the required stiltness, and a ledge or rim along the sides and ends of the bed completes the table. Upon this bed, or floor we place a sheet or layer of india-rubber, J, a portion of, the upper surface of which is provided with numerousparallel grooves running transversely across the bed. A quality of india-rubber which is well adapted for this purpose is that which is com monly used for covering the steps of stairs, and which is known'as stair-rubber. The corrugated portion of this rubber surface only extends from the outer rim of the table to the middle, or perhaps a little farther toward the opposite side or rim, leaving a plain smooth surface next to the inner rim.
A slotted plate, 72., is secured upon thc cross-. beam-b of the frame above each corner of the table 0, and thehanger-rod d passes up through the slot. Each hanger-rod has-a block, e,jsecured on its upper end by a nut, f. This bloc]; has a V-shaped projection, 9, extending, down ward from its lower end. The plate hon one side of the slot has parallel grooves or notches i made on its upper side, in either of which notches the V-shapcd projection 9 will enter and ride as the tables swing back and forth.
By adjusting these rods or hangers in the notches the tables can be made to strike a harder or lighter blow when they come to gether, while the nut serves to give vertical adjustment. Bumper-bars G G are secured to the inner edges of the tables 0 G, oppositeeach other, so that the bumper-bars ofthe two tables meet half-way between. them. I
Two vertical shafts, H H, extendupbetween the pairs of tables, one near each end, and on each shaft, directly between each two tables, is a double cam, I, which forces the two tables apart laterally as the shafts rotate, and then releases them, so that they drop back against each other with a concussion orjar. The shafts H H are driven in a reverse direction by bevelgears K K from a driving-shaft, L, above the frame-work, so that their cams act upon the two tables of each pair simultaneously, and the friction or thrust of one is counteracted by that of the other.
In the upper outside corner of each table we secure a pan,M, thebottom of which is a screen, and the pulp is fed to the screen-pan of each pair of tables by divergent spouts N N, which lead from a hopper, 0, into which the pulp is shoveied or otherwise deposited. The bottom of this hopper is made inclining from its middle in each direction, so that the pulp is equally divided and distributed to the two tables. The pan-screens are secured to the tables, so that they receive the same motion and jar that the tables receive, and this sifts the pulp through upon the upper outside corners of the concentrating-surfaces. A perforated water-pipe, 1), passes across the upper ends of the tables, through the perforations of which jets of clear water are ejected upon the upper end of the tables. The pulp, when thus sifted upon the upper outside corner of the concentrating-sun face, will begin to flow down toward its lower end but the constant motion and concussion or jar will cause the heavier particles to separate and settle to the bottoms of the corrugations and be carried by the concussion directly across the table to the smooth surface,'0ver which they will move in a diagonal direction to the lower corner of the table. The angle which the particles will take on moving across the smooth inclined surface will be greater or less according to their specific gravity, because the heavier the particles the more sensitive will theybe to the concussion orjar, while thelighter particles, being less sensitive, will move down the incline in a more nearly direct line.
At the lower end of each table we secure two adjustable dividers, q q, the outer ends of which can be adjusted toward either side of the-table, so as to divide the moving stratum 0, directly to a receptacle where the concentrations are collected, while the worthless portions in the opposite corner are run to waste. This leaves only the middlin gs which are contained between the two dividers to be disposed of. These middlings consist of small particles of sulphurets and the large and heavy particles of worthless matter that do not become separated in passing over the sur face. The very coarse particles contained in this grade will be worthless, because, if they were valuable, their weight would have carried them into the inner compartment. Hence we mount a screen, Q, over an opening, a", in the table between the dividers, so that the fine particles will pass through the screen and down through the table, and fall upon the table below, while the large particles that pass over the screen enter an opening behind the screen and are carried to waste.
If we use two or more series of parallel inclined tables, the middlings of the upper ta bles will fall into the middlings-departments of the tables below successively, and, finally, the middlings of all the parallel series will fall upon the upper end of an oppositely-inclined pair of tables, U, below the upper series. On these tables the middlings are again subjected to the concentrating action of the lateral vibration and jar, and they fall from the lower ends of these tables upon another oppositelyinclined pair of tables, V, so that by the time they pass over both these lower tables the concentration will be complete.
The principal feature of ourinvention is the new mode of operation, consisting in sorting and grading the particles upon the concentrating-surface, and then conducting only the mixed grade to other tables for further separation, so that clean sulphurets are obtained from the first tables, and the remaining series of tables only separate and concentrate the unseparated and unconcentrated particles. This method insures a complete separation and concentration of the particles without any additional handling, the particles being automatically collected and directed to, upon, and over the successive tables.
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
1. In an ore-concentrating machine, the two suspended tables 0 (J, mounted in the same plane and provided with bumpers GG,in combination with one or more upright shafts, H, arranged between said tables and provided with cams I, substantially as and for the purpose specified.
