erensed 0r magnified, vso 1e speak. As well known, and as I have ilemonstraled by experience, ilie specific gravity of the particles; may be practically increased or magnified by ihe action of centrifugal force sulliciently te make the difference between the heavier and the lighter particles appreciable, and I have found by experience that the particles, while being thus acted upon by centrifugal force and thus magnified or inert); .lull in their specific gravity, may be separated, the lighter from the heavier, by subjecting thnm 10 an opposing current nl water or other fluid of sufficient resistance to carry away the lighter particles, but; of insufficient resistance to :11- rest the heavier particles which, augmented by centrifugal force will pass through the nppesing current, so that 2i separation of extremely minute particles may be effected.

In the description of my impreved apnareins I do not wish to confine myself to the varieus deinils ef construction of the apparatus, as ihey can be modified in various wnyswilhout departing from the spirit of my invention.

- in myim proved apparatus, A is n revolubie ireuuncut-chamber intended in be mounted any convenient, motive I)()rl8l,2ll1(i in which great a speed of revoiuiion may be inrpnrted; is necessary to effect the denised object. I divide the trearinenwrinunher inie we ilnirizenial sections or re rlmentsi menus of a herizenlnl diyidin plute (l, whim n'my be arranged es;- snpperiied in bolts or rivers, as shown in the drawings in usher convenient way. This ilirilln plate is provided with epenings 9 m ably arranged at the outer edge m" the ehn oer, affording (20in illumination between i .l n 5? per and lower compartments of the tree Blight-- chamber. These epenings are preferably four in number, arriinged opposite eaeh ether, although ihdre may be any convenient numher, as the eonstrueter of the apparatus may desire, The treatment-chamber is eovere by a top or norm. l!l,that inintended to extend in an n rim er eeve'ing inelosing the top (if the .l.'1tiliiifih'Cilfi filbQl'i mi-n1 the enier edges inward as Far s In praelinn "Z page Lin fer to extend the cover in about ha f of the distance from the outer edge of the chamber .to the center, as shown in Fig. 2, although this is a matter of construction in which as much latitude may be indulged as suitable to he conditions under which the apparatus is intended to be operated, I arrange a central water-receiving aperture F, extending from the bottom of the treatment-chamber up a desired distance to receive the desired supply of water which is conducted into it through a pipe ffrom any convenient supply. This recciving chamber is provided with holes or openings f between the bottom of the treatment-chamber and the horizontal dividingplate C, through which the water from the pipe f may pass. These holes or openings are preferably four in number, arranged to correspond with the opening I), although there may be any desired number. I prefer to arrange between the bottom of the treatment-chamber and the dividing-plate vertical partitions G, forming passages or channels leading from the holes f to the openings D to conduct the water to such openings to permit it to pass through the dividing-plate into the upper compartment of the treatment-chamber.

.Similar vertical partitions H, arranged between the dividing-plate O and the cover E, form channels or passages from the openings D inwardly toward the center of the treatmentchamber. Around the water-receiving aperture F is arranged a material-receiving aperture I, that extends up from the dividingplate I) a desired distance to receive the material to be treated, which is flowed or delivered into the same through a pipe 2', leading from any convenient source or supply. From this material receivingaperture pipes J extend out into the channels or passages formed by the vertical partitions II and enter the same a desired distance, so that their outer or discharge ends will be under the cover E. Leading out from the passages or channels between the-vertical partitions II are discharge pipes or spouts K, through which the heavier portions of the material treated are discharged by the action of centrifugal ,force. These spouts discharge the material passing through them into an annular trough or receptacle L, while the material that is carried out over the top of the treatment-chamber is discharged into an annular trough or receptacle M. Appropriate spouts N and 0 lead from these troughs or receptacles, as shown in Fig. l, to carry away the water and waste particles and the portions of material, treated which it is desired to save and deliver them at any convenient point or desired vessel.

action of centrifugal force I use a pipe J, as

in the other case extending out from the ma terial-receiving aperture into the int urned end of the water-pipes I. In this case the spout K may be arranged in the pipe 1 cpposite the outer end of the pipe J, and the main .portion of the Water will escape around the end of the pipe J, which is small enough to pern it the water to so escape, as shown in Fig. 6. In this modification of the treatmentchamber it will be apparent that the same effects and results will be secured as in that described in detail with reference to the first three figures of the drawings.

In operation the treatment-chamber is revolved at sufficiently high speed to develop as great a degree of centrifugal force as may be necessary to separate the heavier from the lighter particles of the material to be treated. A stream of water is admitted into the central water-receiving aperture and carried by the action of centrifugal force out along the channels or passages between the vertical partitions G and up through the openings D into the channels or passages formed by the vertical partitions ll, whence the current or stream of water passes inward toward the center of the treatment-chamber to escape over the top or inner edge of the cover E. In the modified form of machine the water passes out along the pipe and turns inward along its inwardly-p o t g p rtion, instead of passing between mrtitions. A stream of material to be treater is now turned into the material-receiving aperture I to be carried by the action of centrifugal force out through the pipes J into the passagesor channels formed by the partitions II or to the inwardly-projecting ends of the pipes P, where the modified form of apparatus is used. As the material is projected or thrown by the action of centrifugal force, it passes out through the pipes J and comes into contact with an opposing current of water. The amount of water introduced to forin the opposing current is intended to be sufficient and 0 538 driven at a sufficient velocity to arrest and carry off the lighter portions of the material being treated,but not to carry off the heavier portions, which are projected through the current of water by the action of centrifugal force to escape through the spouts or pipes K. Of course a certain quantity of water will also escape through these spouts with the heavier particles of material being treated; but as they afford an exit much too small for the escape of the on tire quantity of water introduced a constant current will be forcedinward against the material being projected through the pipes J.

As I have in this specification only claimed the novel features of construction of the appa rains, I do not herein claim the process or mode of operation, but make that the subjectof another application filed contem poranecusly herewith, Serial No. 407,805.

1V hat I regard as new, and desire to secure by Letters Patent. is-

1. In an apparatus for treating and separating finely divided or powdered substances of dilferent degrees of specific gravity, a revoluble treatment-chamber provided with a Wa- (er-receiving aperture and a material-receiving aperture, and passages conducting the water inward and the material outward, substantially as described,

2. In an apparatus for treating and separating finely divided or powdered. substances of different degrees of specific gravity, a revoluble treatmentchamber provided with a water-receiving aperture and a materia1-receiving aperture, and passages conducting the water outward and then inward and the material outward, with an exit for the heavier particles of the material farther from the center of the treatment-chamber than the exit for the main portion of. the water and the lighter particles, substantially as described.

3. In an apparatus for treating and separating finely divided or powdered substances of different degrees of specific gravity, a revoluble treatment-chamber provided. with a water-receiving aperture and a material receiving aperture, in combination with pipes for carrying the water outward and then inward and pipes for carrying the material outward by the action of centrifugal force to meet an 40 opposing current of water,
