To all whom it may concern:

zcnyof the Unitcd State-s. rcsiiling at (lukliind, in thov county of Almuedu and State of California, have invented corn n now and useful Improvements in Coflro-(Jhstl' llxtioulsi-rtionzil view of the same. Figs. 8 and which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to separators for grinding machines and has particularly in View a device of the character specified in which chnii and other light, foreign material mav be separated from the ground material and conveyed to a receptacle.

In carrying out the generally stated objectof the invention it is contemplated cm ploying a suction device which may be opof. Fig. 5 a view in front elevation of the ports of said figure hcin broken away. Fig. *2 is a detail elevation 0 tbs hopper curried or tho suction pipe. Fig. 7 is-a broken ver- 11 arc detailhorizontal and vertical sectional views of the suction pipe showing a draft regulator curried thereby.

Referring to the accompanying drawings by numerals 1 designntcs a suction pipe, one r-nd of which is in communication with a F suction device .3 which may be a fan which operated by a gear 3 held in mesh with a large gear 4 which in turn is operated by 8. small gear 5 mounted upon a motor shaft 6.

- The large gear '1 and small gear 5 are inerated by the grinding machine and pro- Z vided wit. a suction pipe having one and provided with :1 hoppcr through which tln' pro'ectiiw from. the fan casin 9.

gmundinntcrial passes from the grinding machine so that the force of tho suction do- 5 vice is exerted dusctly thereon to cpnruto the forcign material thaw-(from and convey l engages with o lulu (XivHSlOn P2 of on open the same through said pipcand o din-burg:

closed in a housing or gear (using 7, and the gear 3 is'houscd in on outstanding casing Said fun cusingumy he supported by a bracket 10 carried by the base of a grinding inailllle. The said suction pipe 1 has its inlet end provided with n pipe coupling 11 whioh iznliublc fusionor 14. Said hopper '13 is In will be h'lilfirsluml. of course that the essential featurs of the invention necessary in the practical application of the sopurntor are susceptible of a wide range of details j brought into nhnemcnt. \viin the opening 17 and structural orrangomr-ms. but one profcrr'e i and practical cmhodinwnt of the snow provided with an upstanding lip 15- which it is provided with an opening 17 which may no rovcrcd or uncovercd by means of a rota- :nblo sleeve. 1-? surrounding said pipe and provided with an opening 19 WlllCh when The slide vulva 16 serves to oui-ofi' the force in the suction device from the hoppcr 13 top plan view of thr receptacle into which I lhc separated materiul is (lQilvQYWl, showing E the manor-r of connecting the some with the v winding mill and also showing an uir dc l cling sci-con n'nmntcd thzrein. Fig. l i

that whr-i: material is being pulverized by tho grinding machine, the some will not be acted upon by said suction.

The pipe 1 enters the. central portion of he fun casing 9 and delivers the material heroin whcreit is acted upon by the force oi'suid fun and forced out through a. discharge pipe. 20 and into a hopper-shim d fine mosh screen 21 fitted over the siren s! open end of a glass receptacle 22. Soul receptacle .22 has a circular scre .33 suspended therein by means of hol ing clips 24. The screen .223 is provided with a plurality of semi-spherical lugs 25 which are scattered about its upper surface and serve to divide the air current and therehy hrcalc its force and also to deflect the said air to and through the hopper-shaped screen 511 tac e and thus agitate the material therein.

The rcccptacie '22 ma be held in cngagement with the base of tie grinding machine by means of the holding clips 26 which are formed of spring metal and embrace its base. as is clearly shown in Figs. 1 and 3.

The 0 eration of the separator is as foll0ws:- he suction fan being operated by the motor throu h the described gearing, a

strong suction will be created in the pipe 1 which acts upon the material falling from the discharge outlet of the grinding machine into the hopper of the said'pipe, thereby separating the light foreign particles therefrom and conveying; the same through said pipe and into the hopper-shaped screen 21, the mesh of which is fine enough to prevent any of the. material escaping therefrom, but ermits considerable of the air to escape. mm the hopper-shaped screen, the material falls upon the. screen 23 and falls through the same and into the receptacle 2). the air which has not escaped thron h the hopper-shaped screen being deflected y the lugs of said screen 23, as has been previously ex lained.

As he been stated before, the rope tacle is of glass so that the contents thereo may be visible to permit. the attendant. to see when it. is necessary to empty the same and. also to ins ect the contents.

It, will as seen from the foregoing that the described separator ma be readily applied to the discharge en of a grinding machine so that its force of suction may be a plied directly to the material being disciarged, and thus effectively separate the forei 'n material therefrom. And it will also he seen that through the interposed cut-01f 'Jalve in the suction pipe, the separator may be prevented from acting on the material being discharged, so thatwhcn material is being pulverized it will not be drawn through the suction pipe, and through the medium of the described draft regulator thejcree of suc ion mav"be increased or diminished.
