ToV all 'whom t may concern.'

Be it known that I, MiToHnLL R. MANN, citizen of the United States, residing` at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvementsl in Separator-s, of which the following is a speciiication.V

This invention relates to an improved sep- 'aiator and has as one of its principal objects to provide a simple, compact and emcient device of this character for separating metal particles from grain. Y

The invention has as a further object to provide a device that will not choke and which will be adapted to handle heavy feeds aswell as light and feathery feeds'with equal efhciency.

And. the invention has as a still further object to provide a device whereinthe metal particles separated from the grainwill'be collected and retained and wherein provision will be made whereby the device may be readily cleaned of the collected particles.

@ther and incidental objects will appear hereinafter. Y 'Y Inthe drawings:

Referring now more particularly to the drawings, I have shown my improved separator -in connectionywith an ordinary mill 10 having' an intake'spout 11 and provided with a. drive shaft 12 with which are coupled motors 13, all of this structure' beingwell known. In carrying the invention into effect, I employ a preferably rectangular casing 14 which is secured upon the spout 11 to communicate at itslower end therewith,

and leading into the upper end of the casingvr is a chute 15. "The casing may be formed of wood or other approved material and',` secured to the bottom wall of the casing are hinge brackets 16 depending atitheir-foi`` vside by appropriate cat-ches 19.

Mounted toswing upon the depend*- ing forward end portions 'of saidf brackets is appreferably metallic frame 17 andi-:suitablyvsecured to said frame 'is the front side wall 18 of the casing. Thisfront side wall is formed of,coinpositionboard' or other zipproved insulating material land mounted thereon is the magnet asseinblyemployed, the wall being, as shown in Figure 1, nor` mally held to close the ca singat its 'forward Formed in' thevfall 18 of the casingiare.l

Fixed `upon the arms to overlieV are closure plates'` V25 `and rmounted upon 21 are angle ishaped clamping plates 26. These latter plates are secured tothe wall 18l by bolts 27 which" are ,preferably equip! ped with wing nuts. n y

` Mounted upon each pair of varms23 at the inner side of. thewall 18 is, particularly shown in Figuie2, 'a pair of pole plates 28, the several plates'being staggered with re- ,spe'ctto each otherin vertical relation. As best shown in Figure 5, the pole plates are substantially triangular in general 'contour and are 'eachpreferably forinedfroin a piece V'of'suitable resilient sheet metal bent to de- A tine a base flange fromfwhich rises'arear uside flange' and extending from the rear side iiange isan elongated front-flange inclining 'downwardly below the base flangeto define a baffle 29. The base `flanges-are, asshown in `Figure 2, rivetedvv or'otherwise securedto the arms 23,' the bafflesv 29 of one pair of arms co'nfronting,fof course, the baffles of the other pair Vof arms and, aswill be observed,

v saidl baliies are. bent rearwardly fat theirl lower marginslto define channel shaped coli ning,

angle plates 32 through which y are engaerator l approvedtype and mounted upon the drive lecting lips 30. As best shown in Figure 2, the pairs of pole plates are arranged at opposite sides of the inlet opening through the top wall of the casing and secured against the inner face of said wall is a guard member 31 for directing the grainbetween the battles. Fitting in they frame 17 to rest against the outer side of the wall 1S is' a cover' 32 enclosing the lmagnet windings 22 Y and associated parts, the cover carrying o'ed 's suitable bolts detachably 'connecting the cover with the frame. 1

The magnet windingsf22 may be connected' in series and mounted upon the casing is, as shown 1n Figure 1, an appropriate switch 34 for'y controlling the iiow of current through said windings.

In 'any instance where current of suitable voltage is availableas, for instance,'a 110 volt lighting circuit, the magnets may be connected with said circuit. However, where a-'proper current supply is not available, l employ agen- This generator may be of any ticles in the grain will thus beseparated Ves therefrom, the metal particles clinging to the` battles. These metal particles will, due to theaction of thegrain in passing there,- over, be caused to slide down the baffles and under the lower ends thereof to becollected uponthe lips out of the path of the grain stream. Accordingly, theY metal particles. will, after having been `once separated from the grain, be prevented from being dislodged from the bafiles'to becomeagain mixed with the grain and at suitable intervals the collected particles upon the lips 30 may be removed by simply releasing the catches 19 fand swinging the front wall 18 of the casing outwardly when access may be conveniently had to the pole plates. In this connection,

.Y it is to be observed that by providing the depending `hinge brackets 16 the wall 18 and magnet lassembly will swing in a-- wide arc, necessitating correspondingly less clearjance'at the upper end of the casing while feed and other particles will be prevented Vfrom collecting between'the wall 18 and the casing to hamper the closing of said wallv -V against the casing, it being possible to move `the wall to' a position spaced from the easing so that feed in the casing may be brushed -is claimed as new is:

out at the bottom thereof between the casing and said wall.

'I accordingly provide a particularly e'liicient device for the purpose set forth and attention is now directed tothe fact that by removing the cover 32 and loosening` the bolts 2? of the clamping plates 26, the arms 23 of the core bars 21 may be shifted within the slots 2O ofthe wall 1S for adjusting the pairs of poler plates either toward or away from each other. These poleA plates may thus be conveniently positioned for the passage of a heavy grain therebetween orr the passage of light and feathery feed. therebetween. The device is accordingly adapted for a wide rapge of use.
