SPECIFICATION forming part of Letterslatent No. 456,323, dated July 21, 1891. Application filed January 77,1891 Serial No. 377,029. (No model.)

Similar letters refer to similar parts through- To aZZ whom it may concern: v

Be it known that I, PIERRE L. GIBBS, a citizen of the United States, residing at Clinton, in the county of Clinton and State of Iowa, have invented. certain new and useful I'mprovements in Ore-Leaching Machines; andI do declare the following to be a full, clear, and

exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

I My invention has reference to ore-leaching machines in which a rotating annular series of ore-receptacles pass successively under an ore-vat containing the crushed ore in a solution to receive their respective contents or to be otherwise filled and todischarge the filtrate during their transit into a suitablyplaced discharging conduit or launder and at a predetermined point in their orbital movement and automatically discharge the resid uum. 1

The objects of my improvement are, first, to provide a suitably-suspended vat to receive the ore in a solution or dry or roasted ore and adapted by suitable openings in the bottom thereof to optionally discharge said contents; second, to provide a series of leaching-vats to pass successively under said primary vat and respectively receive from the latter a proper quantity of its contents; third, to provide suitable mechanism for supporting and progressing said secondary vats; fourth,

to provide a conduit or launder to receive and carry off the filtrate from said leaching or secondary vats, and, fifth, to afford facilities to automatically discharge the residuum from said leaching-vats preparatory to their refilling. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 is a plan of my invention. Fig. 2 is an elevation thereof, partly in section. Fig. 3 is a partial cross vertical section in the line was of Fig. 1. Fig. 4. is a detail of the automatic trip for discharging the residuum aforesaid.

out the several views.

B is the primary vat, suitably suspended from an upper floor or its equivalent and adapted to receive the ore in a solution,which can be delivered into its upper end in any suitable mode. The bottom. of the vatB has a converging bottom, and at its lower extremity is provided with a transverse series of openings 1, adapted to be optionally opened or closed by a transverse slide d, having a corresponding series of openings 2, adapted to register with the openings 1 and operated .by a lever c or other suitable means.

A A are an annular series of leaching-vats supported cen trally respectively upon a transverse hinge E, seated upon a circular plate 0,

which latter is provided on its lower surface I with a sufficient number of peripherallygrooved carrying-wheels G, adapted to be supported upon and traverse a circular track H.

Near the bottom of each vat A is placed the leaching-cloth 3, of any suitable quality,supported a proper distance above the bottom of said vat by transverse strips 4, provided with transverse openings, thus permitting the fil-' trate to collect between the leaching-surface 3 and the permanent bottom 5 of the vat A and escape from the latter through the exit a.

A suitable stationary discharging-launder I, of a curved formation, extends entirely around under the vats A, having itshighest elevation at one central locality and descending therefrom in opposite directions to' its point of discharge.

b" are attached to the inner end of each vat A, near the bottom thereof, and extend inwardly horizontally to inclose between them the outer edge of a circular plate F, suitably .85 An upper engaging plate I) and lower one supported horizontally to afford in the rotation of the vats A means for retaining said vats in their normal position. In one portion of the plate F is located a rock-shaft'G, provided with the outwardly-extendingnormal guide-surface F and an inwardly and outwa'rdly extendingbow 7. The purpose of this provision is to optionally rock the segment F into the same plane as the plate F, so as to make the latter contiguous, or to rock said too segment below the plane of said plate and substitute in said interval the how '7, which by engaging and raising the projections l) I) will tilt the vat A outward when it is desired to discharge the residuum therefrom, as shown in Fig. 3.

To assist in holding the strainer 3 in position, there-is suitably fastened over the upper surface thereof the longitudinal slats 8.

The plate 0 is provided peripherally with the external gear D, adapted to be engaged and actuated by the pinion P, the latter being driven in any suitable mode.

L and M are liquid-dischargers suspended at suitable intervals above the line of transit of the vats A, and are intended to afford means of discharging liquid of any character into the contents of the vats A during the process of leaching, and N is a similarliquid- (lischarger suspended over the point of discharge of the residuum to assist in washing out the latter when the vat A is in the tilted position shown in Fig. 3.

K is a discharge-trough suitably placed under the point of said discharge and adapted to receive and carry off the residuum aforesaid.

A joint-cover O is suitably hinged on the side of each vat A in position to extend over the adjacent side of the next succeeding vat, and thus preclude a dropping of the material from the vat B between the vats A or on the edges thereof in the passage of the vats A under the vat B. The cover 0 is preferably placed on that side of the vats A which is last to approach the vat B, so that the tilting vat may raise and hold edgewise the cover 0 on the preceding vat and carry upward its own cover.

The operation of my invention is as follows: After the ore is crushed and put in the solution, either originally in the vat B or transferred thereto from other vessels, the power is applied to the gear D through the medium of the pinion I, and the vats A thereby rotated in succession under the vat B, receiving in transit from the latter such amount of its contents as may be desired, and during the cycle of rotation of each vat the filtrate is permitted to escape into and through the conduits or launder 1. Sometimes it is advantageous to introduce some peculiar solution during the process of leaching into the mass within the vats A, and this can be delivered through the inlets L or M, .or said inlets may be utilized to furnish additional water. The vats A may be constructed to contain such quantity as maybe desired, and the rapidity of movement of said vats may be varied at will. If one cycle of rotation of the vats A shall sutliciently exhaust the filtrate, the bow 7 can be adjusted to engage the projections Z) and l) at each revolution of the vats A, and thereby automatically discharge the residuum therefrom in succession, or if more than one revolution be desired the movable segment F can be thrown intothe interval otherwise occupied by the how 7, and thus complete the continuity of the plate F until such time as it may be desired to discharge the residuum as aforesaid, egress of the contents of the vat B being meanwhile suspended by closing the openings 1 therein. As the launder I extends entirely around the circular vats A, the leaching may proceed even while said vats are stationary. As the hinge E is under the center of gravity of the vats A, but one track is required, and the automatic tilting of the vats made feasible without intermitting their support on said track.

Any number of vats A may be used, and my invention may be applied to any operation in which leaching or filtering is involved. The vats A may be loaded by hand and the vat B be dispensed with.
