ORE-CONCENTRATING TAB LE Specification ol Letters Patent.

Application filed November 5, 1907.

Patented Dec. 8, 1908.

Serial No. 400,876.

Ho all whom it may concern:

Be it known that l, CLAUDE Siinnwoon, a citizen of the United States, residing at Black lear, in the county of Shoshone and State of Idaho, have invented new and use- 'tul Improvements in Ore Concentrating Tables. of wh'ch the following is a specification.

This invention relates to ore concentrating tables. and particularly to an attachment to etlect in a` rapid and thorough manner proper grading or separation of metallic values without possibility of their subsequent accidental mixtures, waste, or the necessity of changing the adjustment or set of the table. ythe ataclnnent may be employed with advantage in connection with various types of tables. but is of especial utility when used in connection with an endwise reciprocatory. transversely inclined table.

in the drawings: Figure l is a perspective view of a concentrating table provided with an attachment en'ibodying my invention. Fig. Q is a top plan view oit' the attachment detached from the table. one of the valves, hereinafter particularly described, being separated from said attachment and in perspective. Fig. 3 is a view of the attachment as seen from the table, two of the troughs thereof being` in section. Figs. t and 5 are cross-sectional views on the lines tft and respectively, of Fig. 2.

Like characters refer to like parts throughout the several figures of the drawing.

ln Fig. l a table of known type is shown and generally designated by the numeral 2, and is transversely inclined and given an endwise or longitudinally vibratory or reciprocatory motion by any suitable means for the purpose of stratifying the pulp supplied thereto. rfhis table has on its upper side .longitudinally disposed ritiles with their t'orward ends arranged in step order or are upon a line extending diagonally of the table so as to leave a clear space, as ft. along which the lead separated from the pulp on the motion of the table is fed, the lead, when it leaves the table, falling into an inclined trough 5 secured to the head end of the table in any suitable manner. This t-rough is one feature of the improvement and directs the lead delivered thereinto into any suitable receptacle. The other feature of the .improvement is designated in a` general way by G and comprises several troughs, hereinafter more particularly described.

ln addition to troughs, the member G includes an inner row of connected pockets 7 of any desirable number and disposed along the lower side of the table Q connnencing at the head ond and extending toward the tail end of said table. lnto these pockets lead and zinc middlings and other constituents are delivered and disposed of by means within the control of an attendant, as will be hereinafter made clear. The pockets or compartments may be made in one piece of any desirable metal or other suitable material, and while they may be of any shape they are represented as being substantially square. llach pocket 7 is shown as having countersunk in the bottom thereof a disk valve S provided with a pivot t). 'lhe several valves S are operated by diaimtrcally opposite handles S connected thereto and are held in their adjusted positions preferably by friction. By countersinking the valves in the bottoms of the respective pockets or parti* tions 7, said bottoms will not present on their upper surfaces any projections or protrusions upon or against which mineral values or the like might lodge or catch. In the bottom of each pocket or compartment 7 are three holes l0, ll and l2. Each rotary disk valve S has through it a single hole or perforation 13 adapted to register with any one of the three holes or openings l0, 1l or 12 in the bottom of its respective pocket or compartment 7 for a purpose that will hereinafter appear.

In addition to the inner series of pockets 7 there is a second or outer series of pockets 7, and these pockets 7iL may be of any number; for instance, if thirteen of the pockets 7 are provided, four of the pockets 7a would be preferably used. The numbers of the two series of pockets are simply mentioned, however, by way ot' illustration and will depend somewhat upon the size of the table and dimensions of the pockets. The pockets 7L are constructed like the pockets 7 in all particulars, including the bottom openings, but to avoid confusion and facilitate an understanding of the apparatus, the openings in the pockets 7 are designated by the characters 7 7C and 7, respectively, the pockets TfL containing valves S each provided with a single opening` 8" and operating and constructed exactly like the valves 8. The pockets 7a are coincident with the lirst four of the pockets 7, by virtue of which the first four pockets 7 can discharge respectively into the pockets 7a. The primary purpose of the pockets 7"L is to provide for the proper disposal of the iron that passes over the lower side of the table near the front end thereof, although these pockets can be used to dispose of the Zinc or lead which may be therein by manipulating the valves 8. The valve 8 of each pocket 7 will be turned to register the opening 13 of the valve with the openings 10, 11 and 12 in accordance with the character of the material. owing into the several pockets, and if Zinc flows into the pockets the opening 18 of the valve 8 will be caused to register with the opening 10; if middlings of Zinc and lead are directed into the pockets the openings 13 of each valve will be placed in registration with the openings 11, and if tailings flow into the pockets the openings 13 of the valves will be caused to register with the openings 12. in other words, the several valves 8 will be positioned to relieve the pockets of their contents in relation to the several troughs in accordance with the particular character of the material flowing into the pockets from the table. The registration of the opening 13 with any one of the bottom openings 10, 11 and 12 will result in a closure of the remaining two openings. It is the custom to return the middlings back onto the table to be worked over, while the tailings can be deposited in a heap and also worked over at desired intervals.

Practically the same operation may be effected in the pockets 72l as above noted or when materials of different kinds solely occupy these latter pockets and under this condition of sole occupation of the pockets when the opening 8b of each valve 8a registers with the opening 7d, this is for the purpose of directing zinc through said opening 7d. Then the opening Sb in said valve 8a registers with the opening 7b, this is for the purpose of permitting lead to pass through said opening 7b, and when the opening in said valve 8a registers with the opening 7C, this is for the purpose of causing iron to pass through said opening 7C. By the manipulation, therefore, of the several valves or any one or more of them, the proper grading of the values and other materials that pass off the table can be obtained.

The member 6 is provided with four longitudinally extending troughs 14, 15, 16 and 17 the trough 14 being adapted to receive the pure Zinc, the trough 15 the zinc and lead middlings, the trough 16 the tailings, and the trough 17 the iron. The trough 14C discharges the mass within it forwardly or toward the head end of the table; the trough 16 discharges the tailings therein toward the rear or tail end of the table; the trough 15- discharges into the middlings elevator, not shown, and the rear end of said latter trough is represented as somewhat deflected or inwardly disposed for this purpose, and the trough 17 causes the delivery of the iron in a forward and slightly lateral direction. The four troughs and the trough 5 hereinbefore described are separated from each other in a watertight manner so as to prevent possibility of mixture of the materials therein, and the said troughs may be disposed in cooperative relation to the pockets 7 and 7 a of the attachment in any desirable manner.

From the under side of the openings 10 in all the pockets 7, except the first four of the latter, spouts 10a project for the delivery of zinc which may pass through said openings 10 into the Zinc trough 14. When the openings 13 of the several valves 8 register with the openings 11 of the pockets 7, lead middlings will be directed into the trough 15. Then the openings 13 of said valves S register with the openings 12, the tailings will be delivered into the trough 16. Vhen the openings 13 of the valves 8, except the first four thereof, register with the openings 10, zinc will be directed by way of the spouts 10il into the trough 14, and when the openings 13 of the first four valves S register with the openings 10, the contents of said first four pockets 7 will be directed into the companion or outer pockets 7 a. The materials delivered into the outer pockets 7 a will, therefore, be released and recovered in accordance with the positions of the valves 8a. Should the opening 8b in one or all. of the valves Sa register with a cooperating opening or openings 7d, zinc will be directed from the pocket or pockets 7 a into the trough 14. Should the opening Sb in any one of said valves 8a register with the cooperating opening 7 b, lead will be delivered from the first four pockets into the trough 5, said trough 5 having an angular extension 5a, as shown in Fig. 2, which extends under the several openings 7 b. Should the openings in the four valves 8"11 register respectively with the openings 7", this will be for the purpose of directing iron into the trough 17. Therefore, by the manipulation of the several valves the constituents discharged from the table may be separately recovered or properly graded. Should the valves St1 be set for effecting the discharge of iron into the trough 17, and should it be seen by an attendant that Zinc or lead is being delivered into the pockets 7 "L, such latter materialscan be directed into the proper troughs by a simple manipulation of the valves SZL without changing the adjustment or set of the table, witlrrespect to the pockets 7 and the valves S.

From the foregoing description relating to the discharge of the individual materials t or substances through the outlets et' the pockets 7 and 7a and into the several troughs mentioned, it is not to be understood that ditferent materials are simultaneously liberated from each pocket, but that when one kind ot material is flowing into each pocket, that material may be liberated into the proper trough Which has been devised for the purpose.
