To rr/Z/ whom, it may con/came:

113e it known that l, `l I Iiiuir P10-Ordin TAY- Lon, a citizen of the linited States, residing at Alfloward, in the county of Crook and State of Oregon, have inventml certain new and useful 11n rovenicnts in {vh'e-Concentrators, of which t ie following is a speeiiication.

My invention relates to improvements in eon'centratiiig-tahhs whereupon ores are separated from the refuse tailings and from. each other according to their speciiic grav-ities.

It consists, essentially, of a longitiulinallyinclincd-sup1'iort, a traiisversely-inelined bed upon this support, means by which these inelines may be varied, a shaking-table upon this bed, means by which a movement is given to this table oblique to the longitudinal line of' the support, n'ieans by which the length of this movement or stroke may be regulated, and of details incre fully explained by reference to the following' specihcation and accompanying drawings.

Figure 1 is a plan of my invention. Fig. 2 isa longitudinal elevation. Fig. 3 is a part soctionand elevation on the line 9c` fu of'Fig. 1. Fig. 4 is a rear elevation. Fig. 5. is an end view. Figs. 6 and are detail views of the driving mechanism.

The object of my invention is to provide a device in which I get the widest range of position and movement possible for the concentrating-.table may be best adapted to the' Varying'kinds and grades of ores under treatment. It is capable of being given a longitudinal, a transverse, and a diagonal tilt at one and the saine time., or it may be given any of these tilts singly, or it may remain horizontal, and in-anyY ol these positions the movement or length of stroke of the table is capable. of variation at will.

Having reference to the drawings, A is a suitable foundation or baseonwhich the A frame B, c0mpose-d of longitudinal timbers suitably connected, is pivote-d at one end, as at 2, to the base A, so as to be capable of being given a longitudinal tilt. rThis tilting is eileeted by an inclined-plane lifting mechanism secured upon the parts of the base and the. frame, near the opposite end from thepivot 2, as follows: On each of the longitudinal pieces of the base A are similar sliding wedges 3, hav ing projecting ilanges by which their position on these pieces is maintained. One of theseilanges of each wedge is notched to form a rack-bar 4. A pinion 5, having an axle Journaled in the base, engages with the rack and by suitable means, as a lever 6, is operated to move the wedge. Secured upon .the frame B are rollers 7, which are adapted to engage the inclined faces of the wedges 3. A' simultaneous movement of the levers moves the wedges forward' or backward and corre spondingly raises or lowers the end of the franie. A bed portion O vis hinged at 8 to the traine B. By nieans of these hinges the bed C is transversely tilted by la mechanism somewhat'sirnilar to that used in giving the irarn' its longitudinal tilt. Upon the opposite side of the bedirorn the hinges are the wedge portions 9, fitted so as to slide upon the inclines 10,. carried upon a rod 11, which latter is secured to thelongitudinal ortion of the frame B. The under side of this aris provided With a rack 12, and a pinion 13, journaled in the frame, engages this rack and is actuated as by means of a lever 14. Thus by means of the lever 14 the wedges 10 are simultaneously inoved and the lateral tilt of the bed and the table varied. The shaking or concentratingr table-I) is supported above the bed in such nia-nner that it may be given a rocking or sliding movement in a direction oblique to the length of the machine. Such mounting I have shown by the standards 15 upon the bed, having their ends adapted to lit the cleats 16 on the bottom of the table and form sliding bearing-surfaces The table is of irregular shape, having its head 'end narrowed. The pulp is fed in, as at 17.

Parallel with the longer and outer edgeof the table are the riilles 18. which may be either rectangular or otherwise formed in any wellknown manner. lfVat-er 4is fed along the side and end of the. table from the trough or perforated pipo 19. The object of inaking 4this table with its eut-er edge longer is to com ensatc in a. manner for the longitudinal ti ting of the table and lo raise that edge of the concentrate end which would naturally be lo\ver, so that 'the water may tend to flow toward the head and be equally distributed over the table. soon to be shown, the valuable particles or the `"coneentrates will be carried uphill toward the concentrate or broad end of the table by means et' the riflles and the shaking of the table, While the slime will How oil on Furthermore, for reasons` shaft is a coneshapedcam 2l.

the lower or tailings side d.v A dilerential reciprocating movementin the direction of the rxles is given to-this table in the followingmanner: At the head end of the nia-I chine a horizontal shaft is Iiournaled in a framework E and has suitable driving oonnecti'ons with al source of power.

A s eeve 22 u on the shaft has one end -abutting against 't e base of the cam and the other end is threaded, on which the stroke-adjuster 23 is tfurnable. This adjuster is held between the guides-2401i theframework E. The sleeve 22 is prevented from turning on the shaft by means of a longitudinal groove 25 inv the sleevev in which a ro'eetion or lug 25 on theframe-engages. o t e head of the tableis attached an arm 26. The outer-end of this arm has lawheel'27 running ori the face o f the cam... This wheel is kept against the cam by reason-v of a spring 28. The tension of this spring is'regulated by aflanged sleeve 29= .u on. tlii'eadedand'is turnable in a threaded pro- .jection-BUofthe-framework E and is operc atedby'means of the spokes 31'. By-means of'the' movable sleeve-22 upon the`shaft'2() 'against the cam to move the latter, so

f thew `ee1=27 runs upon a greater orless-circumference of the cam, I ain-able to give any desiied lengthvof: stroke or "shake tothe table; This ability to change the shake-ol the table is of. great value in many instances.

. The cam is given such a peri hery that a difcomes to a quick stop on-the concentrate end of its stroke and' to a gradual sto ferentialmovement is gaine e., the table `end of the table and effects a cleaner and closer savi than is usual in concentratingtables', thily reasonthat the slime is carried in lanother direction-fi. e., toward the lower side dand the particles have more freedom to separate according to their relative specific gravities. found that by the use of this machine the finely-ground ore may be concentrated in a drystate-a feature that is of immense value in dry and arid localities where conservation of water is of first importance in all operations.
