My invention has for its object to provide a separator that may be used for separating magnetic substances from nely divided materials as they are passed through a chute or container of 5 any form. Thus the invention may be used for the removal of magnetic material or articles from a mobile material. Particles of foreign material, such as nuts, small nails and tacks, which occasionally nd their way into grain 1o While being handled between the harvesting of the grain and taking to an elevator, invariably does damage to machinery used for grinding or pulverizng the grain, or to cattle if used for feed. Also, in pulverizing the grain a risk of `fire exists if such articles are present by reason of the heat emitted by the breaking or striking oi the iron particles in the atmosphere of dust created by the grinding or pulverizing operation. The invention may be used in connection with 20.apparatus of different kinds and may be em bodied in structures that vary in their details. To illustrate a practical application of the invention, I have selected a structure containing the invention as an example oi the various em- -bodiments of the invention and shall describe the structure selected hereinafter. The particular structure referred to is shown in the accompanying drawing.
Fig. 1 is a perspective view of the separator se- 30.lected for purposes of illustration. Fig. 2 is a top view of the separator. Fig. 3 is a View of a section taken on the plane of the line 3 3 indicated in Fig. 2. Fig. 4 is a view of a section taken on the plane of the line 4-4 indicated in Fig. 2. Fig. 5 illustrates a counterbalancing Weight for counterbalancing the separator.
A chute 1 is located at the desired angle to enable nely divided material to move along the chute by its own Weight. The bottom of the chute is provided with an opening 2 which may be closed by means of the separator 3. The separator is contained in the sheet metal box 4 that is hingedly connected by means of the hinge 5 to the upper edge of the opening 2. The hinge 45.5 is connected to one side of the box 4 and to the under side of the bottom of the chute 1.
The box 4 is formed, preferably, of sheet iron and an electro magnet l0 is located within the box 4. The core 11 of the magnet 10 is formed of a plurality of sheet iron strips which form laminations when placed together to form the core 11. The core its between the sides of the sheet iron box 4. The laminations or sheets that form the core are provided with slots so that when they are placed together they form the channels 12 in which the electric coil 13 is inserted. Bars 14 are secured to the protruding parts of the core 11, each bar extending over a portion of the coil and lengthwise of the box. The bars 14 are formed, preferably, of soft iron 60 and form the poles of the separator. When the separator is connected to the chute 1,l the bars 14 extend across the bottom of the chute to produce two elds extending across the bottom of the chute and between the poles, whereby all of the material that passes through the chute will pass through the elds produced by the coil and the poles. The coil 13 is connected to the source of supply of electric current, such as to the mains 17-17, through a switch 16, whereby the 70 circuit of the coil may be opened and quickly closed. This operates to open and close the door and to discharge the iron particles when opened and reclose the chute to allow the grain to pass over the door.
In order that there may a free flow of the non-magnetic material over the separator, a plate 20 of diamagnetic, such as copper or brass, is secured to the box by means of the screws 21 which pass through the ends of the outer bars 14. The plate 20 ts the opening 2 and when the separator is located in position to close the @Dening 2, the plate 20 is located ilush with the inner surfaces of the bottom of the chute in order to permit free movement of the non-magnetic material over the separator.
An iron bar 25 extends lengthwise the chute and across the opening 2. The bar 25 is, preferably, triangular in cross section and terminates intermediate the upper and lower edges of the opening 2. It is brazed or secured to brass blocks 22 that overhang the edges of the sheet metal chute 1, and which are brazed to the bottom of the sheet metal chute to locate the inner ends of the bar 25 well within the edges of the opening 2.
The Weight of the box is counterbalanced by means of the weight of the metal block 27 which is located on the arm 28 that protrudes from the corner of the box located below the hinge 5. 100 When, therefore, a. current is passed through the coil 13, the attraction created by the poles of the magnet for the bar 25 will lift the box to close the opening 2. The grain, or pulverent material, is then allowed to pass along the Vchute 105 over the plate 20 and the magnetic material, passing through the chute, will be magnetically held on the plate 20 by the eld of force of the electromagnet. When the movement of the finely divided material discontinues through the 110 chute, the circuit through the coil 13 is opened and, owing to de-magnetization of the poles of the magnet and the weight of the box, the box immediately swings on the hinge 5 and opens the bottom of the chute. 'Ihe magnetic material that has been caught on the surface of the plate 20, immediately slides down the surface of the eld but does not have opportunity to continue down the chute on account of the opening of the chute by the movement of the box. The plate being formed of diamagnetic material, the magnetic particles caught by the electromagnetic eld will be immediately released and fall outside of the chute where they may be collected, if desired, and removed.
I claim:

In a separator for separating magnetic material from mobile material, a sheet metal guide for the materials, the bottom of the guide having an opening, a sheet metal box hingedly connected to the Lipper edge of the opening, a coil having a core of magnetic material, the core having a pair of channels for receiving the coils, bars of magnetic material secured to the core and extending over the coil and parallel to the upper edge of the opening, a plate of diamagnetic material covering the top of the box and the said bars, the outer surfaceoi the plate located substantially flush with the bottom of the chute when the opening is closed by the plate, and means for closing the opening by movement of the box on its hinged connection with the chute.
