FEED CLEANER FOR GRAIN GRADER SAMPLE DIVIDERS Filed Aug. 12, 1940- Patented Jan. 6, 1942 UNITED STATES PATENT oFFlc E FEED CLEANER FOR GRAIN GRADER SAMPLE DIVIDERS Homer L. Brundage, Toledo, Ohio Application August 12, 1940, Serial No. 352,245

3 Claims. (Cl. 209-223) This invention relates to culling out magnetizable matter from grain tester samples.

This invention has utility when incorporated in a cone spill receiving electromagnetic device feed to the hopper of a sample divider.

Referring to the drawing:

Fig. 1 is a side elevation, with parts broken away, of an embodiment of the invention as adapted to a sample divider for grain graders;

Fig. 2 is a section on the line II-II, Fig. 1, showing the view looking down on the magnetizable cone or metal accumulator part; and

Fig. 3 is a section on the line III-III, Fig. 2, showing the relation of the supply feed section to this magnetizable cone and its chute therefrom to the hopper.

In practice, grain standards have to do with gathering samples of cereals, legumes, seeds,in say 5 or 6 pound bags or thereabouts. Such samples for the grain tester are poured into hopper I of grain divider device 2 in the usual course of working supply material 3 from bag or packages 4. These samples, Whether beans, seeds of the smaller type, or even wheat, oats, barley, or corn, in the harvesting or processes .as variously handled, especially by machinery, may at times ac cumulate foreign material which it is desirable to cull therefrom. A character of this foreign material which may be contributed by the containers or parts of the machines through which passing is of the magnetizable class and may be small nails, nuts, bolts, etc.

In the practice hereunder, electric supply 5 may have fixture 6 with conductor line I therefrom to switch 8 with conductor lines 9, I 0, therefrom. In the event this supply current be direct current these lines 9, I0, may be directly connected to terminals I I, I 2, at insulation bracket I3 on upright bracket I4 from chute l5. This chute I5 has additional brackets I6 therefrom, which with the bracket l4 mount supply or feed way tapered hopper or cone I! to receive the spill of granular material 3. In the event the electric current or power supply at fixture 5 be alternating, the lines 9, I0, may connect to lines I8, I9, of rectifier 20, say of the radio type, at which switch 2| may function through the action say of a transformer and six ohm resistor so that the volt supply current may be brought down to 6 to 8 volts as taken from terminals 22, 23, by conduit 24 to the terminals II, I2.

From the terminals II, I2, extends conduit 25 to coil 26 in cup 2'! carried by radiating arms 28 centrally of the chute or duct portion I5. This 5 cup 25 as carrying the coil 26 has top closure 29 upon which rests tapered insulation or wood ring 30. In the ascent of this ring 30, it is flush with core 3| of this electromagnet coil 26. This core 3| has tapered apex 32 located centrally of spill opening 33 fromthe supply way II. Accordingly, with this electromagnet energized, whether by a 110 volt direct current or by the lower voltage rectified current, spill of granular material into the way I! has such in its downward travel directed against this apex 32 as magnetized, whereupon this magnetic material adheres thereto as the regular seed or grain is free to flow in this angle of drop. say of approximately 30. Thus the supply of the granular material freely flows from this supply way I! past the magnetic collec- What is claimed and it is desired to secure by 7 United States Letters Patent is: I

1. For assembly with a sample divider of the grain grader type having an upwardly open circular hopper, a chute for delivery to and mounted on said hopper, a circular tapered portion centrally in the chute having a central magnetic and a surrounding non-magnetic face section, and

directing means providing a spill of granular m aterial to lodge directly on said central face to spill therefrom over the non-magnetic face and be then directed by said chute into the hopper with the magnetic face section effective to retain magnetizable material thereon as the non-magnetic granular material passes therefrom.

. 2. For assembly with a sample divider of the grain grader type having an upwardly open circular hopper, a chute for delivery to and mounted on said hopper, a cone centrally of the chute, said cone having a magnetic apex section flush with a non-magnetic frustrum section, .and directing means providing a spill of granular material to lodge directly on said magnetic apex section to spill therefrom over the non-magnetic frustrum section and be then directed by said chute into the hopper with the magnetic apex section effective to retain magnetizable material thereon as electromagnet having an apex filler for the ring as a continuation thereof in forming a cone, and

directing means providing a spill of granular material to lodge directly on said magnetic apex for the non-magnetic material to be directed therefrom by said chute into the hopper with the magnetic apex effective to retain magnetizable material thereon as the non-magnetic granular material passes therefrom.
