d The Scheule refan'e to in these v'Letters Patent and making pan: ox me same To all whom it 'nuty conccrn:

. Be it known that I, Ronnnr Gnonen, of Denver Uity, in the county of Arapahoe'and Territoryof Uulorado, have invented a new and usefnl lMachine for Separatiug and Conoentrating Materials of Different Specific Gravity, metals,rocks, allurials, and any metalhn'gical `and organic fossil snbstances contained in an admixtnre or natural strat-a, or iu a chemical combination; and do hereby declare that the following is a fall, clear, and cxact description of the construction and operation of the same, reference being had to the annexedldiawings making a part of this speciiication, iu whichi Figure I, shect 1, is a plan. FigureII, sheet 2, is a front elevation.

i Figure III, sheet 3, is a side elcvat-ion.

a Figure IV, sheet 3, is a trans\'erse section on the line A B.`

Similar letters, in* blue ink, refer to 'similar parts The nature of my'im'ention consists in the construction of. a. machine possesing the following properties, and designed-' irst, .to sim'plify the process of concentrating and1 'K separating all kinils of useful andi'aluable ores and= i' mineral substances, during the process of dress'ing (sepV parating) from rocky matter-s, andl other injurious or extraneons substances, for the purpose of theirsubseqnent metallurgical treatment. .Secondly, to save, unaided by any other apparatus or appliance whatsoever, all of the preciou's meta-is o'r other useful and val'uable mineral snbstances undergoing the process of crushin g and separation in stam pthe great `loss accrning by the use .of the amalgamatheretofore used, to' save and concentrate the useful and valnable miuerals for their subse'quent met-allur- Thirdly, to 'save the preciousnietals contained in alluvials, orvso-called dry placers.

and'mincmls for paint-s, &c .,-f rom injurious'and'ex-'- traneous snbstances, as 'iron pyritfes, slate, sand, &c. To enable others skilled in'the alt to make and use my invention, I will proceed to dcscribe the constrnction and operation of .my machine.

a The machine consists of two maml parts, viz., the

outside frame-work K and the separating-chamher I.- l In order to charge ,the machinel with materials to bo according to their size; 'if'they consist of rocky matters m large lumps, they ought to be c'rnshed either through a series of seives, 'to render them fit for chargin g. When the materials to be separatcd are found in alluvials,'ns is frequently the case of the precious meta-is, in dry placers,*&c., it will sniiice to separate the larger rock or gravcl by merely screening it..

The material thus assorted' is charged into the hopper A, and spread evenly.

The damper al is then opened, by the screws a2 a", a suflicicnt' width to fill the ilutes of the roller B.

The motive power to work the machine may be applied either to the sbaft of the roiler B, or to the shaft G; in either case, the intermediate wheel F willtransmit 'the motion from B to G, or G toiB. W

To the shaft G are fastened and attached the` lifting-wheels (ll and'dz, the cam-Wheels c' and-eand the spur-wheel II.

The fraic-\\'oi'k of the separating-chamber I rest on its front part on Indiarnbber cushions or metalli'c spi'ingS, marked 'vI 1:20, which said cnshions or Springs are kept in position by boxes fat-ened to and supported 'by the front bar L, of the main frame-work K.

The rear partof the separating-chamberis suspended by the swivels i* iz, attached to the main frame-work When the machine is set in motion, the' ioller B, revolving, discharges' the contents at about the center of theraised back of the separating-chamber I, whereby the same are eyenly spread over the rear side of the sieve O', at the same time the separating-chamb'er I is lifted by the wheels d1 dz, which causes 'the charged materials to oscillate rertically on the sieves, while the cam-Wheels cl o* move the separating-chamher borizontally backu'ard, until the prolongations q1 g2 slide ofl' from the engaged tooth of the wheels c1 ez, at which moment the Springs f2 reverse the motion of the separating-chamber I, and force it to the front bar L,

producing thereby a horizontal .concussion of thecharged materials, which forces the same i'onisieve cI to sicve cz and c, iu 'order'to facilitate the forcing or sliding of the. charged materials, more speedily towar'd the front of the machine. The lseparating-chamher I may be raised iu' the rear by the swivels i' iz, 'in such a mann'er 'that the sieres cl cz c'i will be placed on an incline toward the front of themaclrlne.

The Velocity of the st'rokeof theprings l-24 is regulated by the screws h* hi. The separating-chamber I is connected with the .slotted pipe C by means of leather,rubber, or metallic paching x, snfliciently pli'able, so as not 'to interfere with the'oscillating and rising movements of the separating-chamber.

If the machine is chargcd with materials iii a dry state, air is forced in under sieves cl cio3 bya bellows fan, or other blowing apparatns, connected with the at the same time,

the troughs ml m2 111.",as

v pass, this will pipe O. The continuous oscillations of the materials on the sieres c' o c" will facilitnte the passing npward of the air through the ch'arged materials, wheiehy the pnrtioles of greater speeiiic giarity aecumnlate on the bottom of the sieres, while the lighter ones aremised to the surface of the agitated materials.

To separnte the heavier particles from the overlying iighter ones, in a continuous manner, the sieve o' 'is orerlapped byA the metallic stripj', which said strip, forms a rim over the edge of o* in like mam-ier c' is overlapped by j', and c1 b 'j The overlaps j' j'- j are 'secu'rcly fastened to the lnrslc'k'k1 which said bars k' k kl are fltstened and a.tl;.'\ohed to the separating-ohmnber-by'the screws Z' i, hy means of n'hieh seren's the said bars kl k' If can 'he' raised and lowered, therehy u'idening and narrowing the intelstlees formed hy the .etripsy'fj'ig'a and the sieres c' o' clfia's may be required for the admission. of the. partielesof greater specific gravity into the troughs of which said troughs, marked m' mam, are pmvided with a morable and detached hottom, suspended Scale-like, as scen by p', and which said hot-tom can ,be raised or depressed by means of theiegnlating-screws n' n, to such a degree as to form anl'joritice suflieient to allow the separated materials to ;make their exit att-he edge o; while, in this manuer,

the vnlahleorheavierpartieles make their exitt-hmugh above -described, the lighter orexhausted maten'als have to pass over the dalnper i'. -The latter is so eonstructed that it can he easily raised or lowered in a cnrrilinear' manner, as the na tnre of'materials ou the sieres cl c2 o' may require, fora perfect separaton. If the damper 'r is`.raisedv by'the rogulatilig-sere-r q' q, with which it is provided,-"so l'ar as to tbrm a small interstice between it and the overlapj, through which the partieles from the undermost ot' the materials sliding over the damperr can aifrd theoperatora criterion-to determine whether all useful 'and valuable materials are exhausl ed and sie ed or not; vlf there are any passing theletln'ough, the same will be saved by passing over the apron t, while the exhausted und extraneous materials are carried oil'over the apmn u.

Ifthe charge is in a wet state, as, for instance, the tailings from `stamp-mills, water may be iutroduced, instead of air, or;water and air together, in a. similar manner as that stated for the introduction ot' air alone, through the pipe O.

The Velocity of the flnted roller B'for chargingis calculated to he liteeu revolutious per minute, and, as-

four'flutes, with a depth of the roller is provided with an inch each, and being six feet long, the capacity for lcharging will be 333.84 cuhic inches per minute.

Snpposing that the charge consists of common goldbearingquaitz or alluriai, the machine will lsepal'ate eiglit tous and fourteen hundred pounds in one hour,

or in Yten hours, the gold coatained in eighty-seven tons of quarts or alluvial, a capacity aimost higher than practicable operation will reqnize in any of the afo'resaid mses. The appiimhility and utility of my machine 'are erident from the 'oregoing.

What I elaim as my inventon, and deslre to secure by Letters Patent, is- I 1. A maehinefor separating, ooncentmting, and saving the precions metals, and other valuabie-and useful minelnls or fossil substances, as the same exist and 'are found, either in a orude state or artiiicially produced by chemicalcombiuations or technical admixtures, armnged, eonstructed, and operated in the' mannerand for the purposes hereinbefore deserihed and set forth.

2. The sievesic' c'c'l, together with theirarrangements and connections to form the adjustahie intersiiees.
