To all whom it may commet:

'Be it known tlmtl, JAMES W. Rumen, of Louis, in tho'county of St. Louis, and of Missouri, have invented a new and*improvcdMLrushing and Grinding-Micahine;1 and I do hereby declare that the following is a full, cleer, and exact description oi the same, reference being had to the accompanying which- 'Figure l'represents a sectional elevation of a crushing and grinding-machine, constructed according to my improvement, and

Figure represents a horizontal section of the same,

'-drs'wingforlning s part of this specification, end in taken through the line :n z in figfl.

Similar letteisjoifreference indicate corresponding parte iu both figures vThe invention relates to that clase oi crushing' and grinding machines in which aconicul gainderor ernsher,

.- with concentric und eccentric bearings,is upenotedwitin *in s' stationary upright cylinder or chamber, or in which.

` the erusbiugchambr made conical., ond the erzieher straight; and

The-invention consists in s.' universal or bollentisocket support above the cylinder, from which the crushing-cone is` suspended on en oscillating arbor, rigidly-connected with a rotating eccentric box carrylng its lower extremity, an'dwhieh is fitted in the hub cf a horizontal geor-wheel, so .as to rotate, in en annular conical orbit, within said gear-wheel, but having no rotation on its own axis, whereby a grinding er ribbing-action, as weil as a crushing effect, is pri duced, instead of n crushingwotion only, as in similar,

machines, wherein the cone rotates around its own Axis; also, in the combination with auch ornoner and its cylinder or chamber, of. s gaugeqing, of novel charscter, whereby ore, or other xiiaterial to he crushed or ground, when placed within the cylinder, is' checked, in its descent, and prevented from passing out until has b een sutlciently reduced by the action of the orusher; and furthermore, .iu the combination with .Ilich gauge-ring and cylinder', of a stripperor clearer, to remove any adhering substance from seid cylinder.

In order that others may nndelntand the construction l nd operation of my invention, I willl proceed t0 describe, with reference to the drawing.

A is a hollow cylinder, constructed of cast-iron, or

other metal, with enlarged upper and lower extremities, and arranged in a vertical position, resting upon a. horizontal base, la.

B is 'a Crusher and grinder, of conical or tapering form, and secured to an oscillating arbor, D, suspended from the cap of the cylinderl byneans of a universal holland-socket joint, E, and is' made to Swingin a.

conical orbit around the exis of the cylinder,- by the rotating of an eccentric-box, 0,' carrying the lowercxtremity of the nrlmrD'and fitted in the hub cfa horizonralgeenwbeei, G, arranged under tbc bose-plate t, and driven by s pinion. 7t of a suitobly-armnged countersiinft, H. i

C is o: gauge-ring, constructed of iron, or other metal, and, preferably, of'a form as represented in tbedrawing, but may' be of any suitable formforeffecting the purpose for whichiit is designed Sai gauge-ring O is carried upon the upper ex- 'tremit cf the hub of the said gear-wheel G, withv its upper vsurface fitting against the under surisce of the grinder B, and serves to preventlthe downward escape of the material before it has been sulloientiy reduced, but permits the ready escape of said mateal alter it has been sufficiently reduced, by means of an annular space, c, leit between its outer edge and the inner-'surface of the cylinder, and, its lit tunis with thc hub, it also serves, to sorne extent, as e flistributer, changing the position. andlooality of the, lumps orpilrticles'. of i the mziterini at the bottoni, und'tbus vpresenting newsnriaces 'thereof to the fiction ofthe orusher.

Said gauge-ring G is, or may be, provided with a clearer or stripper, j. Said clearer or stripper j is 'constrncted of steel, or other rsuini-ble metal,`nnd is so u rranged as, by the rotating of said gauge-ring 0, to

scrapeagninst the innersuriitce oi'the lower p :utof

the cylinder A, immediately behindthe point where to prevent the adhering vof the material to the surface. This stripper or clearer lsnnnecessary, exceptin grinding such materiales is liable to adhere to the* cyindcr when in a. crushed or powdered state Suitable openings, a a, are made in the cap, for im sertion of the material to be crushed or ground; and, also, similar openings, o o, are mode through the baseplate b and gearing-wheel G, for the downwardpassage ofthe said material, alter it has been crushed or round. g Motion is imparted to the shaft H any ysuitable application of power, and the matcrialfsdin at the top, gradually works its way downward by action of- .graviim es in otherlvertical crushers cr grinding-msreduced, according to the locality it occupies in the A cylinder. 1f near the top, as: at'K', it will be brokenV into two or more laces; but if it be small enough to Ile y nesr'tlxo bottom,

f vn, n will be reduced w. ver

or to powder, itsiino ess dir pending upon or mzufhixrc; also, additional griiiding-lurfxwesorplatea, if necessary, may be arranged below tho crn'sher, for

. giunugl material.

In this alrangeiucnt, the crusher B does not rotate on its axis. '.llle orc, or other material descends, ns its lnlul's or particles me reduced, until it reaches the tace of `he gauge-ring (E, where it is checked in'its downwaml motion, and moved round with the .aid gingen-ing, by the friction'of its surface, until said lumps orpzuticlcs, by boing subjected to tho repeated crushing and grinding-action ot' the erusher, become sulicientl'y reduced todi-op through the annular space e. The erushing-clnnubcr A need not necessarily be of cylindrilxtirin'iu ou its inside, but of polygonal or va-V ried configuration, and may be made tapering or conical, instead of the ernsher B, which may be made straight. l,

Different constmet-ions, also, may be adopted for feed and delivery oftlm material to und from tho mill lich the eccentric-b0x c and gauge-ring@ further inducing or fino and desire to have seemed by Letters Patent, is

l. The cone B un the arbor I), when sustained and operated in such manner as 'to swing in a conical orbit around the, axis of its surmuuding cylinder, Withont rotating alunni] said arbor, substantially as set forth.

2. Thu gauge-ringl (j, arranged and operating in combination with t-he cylinder A,'and crnsher or grinder 1l, substantially as and for thel purposes herei in set forth.
