' ness and simplioiy, and 'which will BE-NGENTRATR Application i The present invention relai/es to novel and useful improvements in ore .coi centrators, and has particular applicaiic-n lo a device of the class described adopted especially for the concentration and separation of dry ores.

En carrying out my inventioiiyii isl n3 purpose to provide a conceneracor Wliicli will embrace the desired features ci el c ually and conveniently separae the valuableore from the Waele or diriJ with which the ore is mixed.

tis also my purpose oprovide sructure in Wliicli che material 'lo be concentrated is introduced to the separator through a tube and acted upon by e. lolasiI from a particles of ore dropping into Various 'pockets according to ilieir specific graviy ivliilethe tailings or Weste are carried by a sec ond fan to a point of discharge.

With the above-recited oojecs and others of a similar nature in View, tlie invention consists in the construction, combination and arrangement of parte, set forth and 'falling .vitliin the scope of Lilie appended claims.

In the accompanying drawing-Figure l is a view in side elevaion of an orc separator embodying my invention. Fig. 2 is a lon.' gtudinal sectional View. Fig. 23 is e iop plan view. Fig. i is en end View,

Referring now to dieaccompan lig drawings in detail, *die numeral L indicates lie casing or body ci the conceniralor wliicli is provided preeiably adjacent io one end with a hopper Q through Wliieli -lie ore is into the body of the casing, the leerer being provided at its bottom with a series of poclreis 3 preieiably V-shaped in form which :nagv be higher 1t-the back end so as ro concentrate while sliding ouiJ oy '1 ranged ai one end 'of the trough is A ing 4, for the fan or blower 57- tiie lett being mounted upon the power elia-ift which is driven oy means of lic Jari speed pulley 7, the outlet lglie fan 8 (liscliarg'ing tlie blast into tl'ie chamber i directly beneath the liopger an against lic material passing from ille iopper to elle alien. ez

From the above descripion, aken in conlie consruccion and operation of my 1inroved ci'incentrator will be readily anvar- L The fan is started :it elle desired sneed nd 'the material is dumped. into the liopo i passing thence into the casing or cliamloe s the material falls in ehe casing, the ci air from the fen strikes lie seme ilie particles of material are driven long through the casing7 and drop 'into elle Links athebottom of the casing according 'eo their specific gravity. The sucion flan oiitop of the casing draws *elle lighter inaterial suoli as the tailings or Waele through the spiral conduit and ioreesA such tailings through the discharge ulae 13, any particles of ore'wliicli may be mixed with che ieilinggs dropping into lie pockets in said. discharge tube While the miste is discharged fblrougli said uloe.

iii)

ing, a feed hopper for the material leading into theupper side of the casing`near one end thereof, a pressure blower vcommunicating with the casing at one end thereof aidjacent the feed hopper and adapted to discharge a current of air against the material falling into the casing from the said hopper, a spiral conduit connected to the end of the casing opposite from the pressure blower and in avlineinent therewith, a suction fan mounted upon the upper surface of the oasing, a housing for said fan, connections betWeensaid housing and spiral conduit Whereby the vtailings from the mass of material',

are drawn through the spiral conduit to the housing by means of the fan, and a discharge conduit leading fronr said housing and provided with a, plurality 01"' pockets substantially as and Afor the purpose set forth.

In testimony whereof I ax my signature in presence of tWo Witnesses.
