'- GRAVITY GBAIN-SEPARATOR.

Specification tr Letters Patent. Patented Sept, 28, 1920.

r A'pplication filed August 2, 1919. Serial No. 314,994;

Toall whom it may concern Be it known that I, ANNA J. SOHLUNKE, a

citizen of the United States, residing at Fargo, in the county of Cass and State of North Dakota, have invented new and useful Improvements in Gravity Grain-Separators, of which the following is a specification.

The object of my present invention is the provision of a grain separator in which the operation is effected entirely by gravity, and which is therefore extremely simple and inexpensive in construction as well as durable,

I the latter being largely due to the fact that it is unnecessary to incorporate movable parts in the separator.

To the attainment of the foregoing, the invention consists in the peculiar and advantageous gravity grain separator hereinafter described and definitely claimed.

In the drawings, accompanying and forming part of this specification:

Figure 1 is a longitudinal, vertical section of the separator constituting the best practical embodiment of my invention that I have as yet devised.

Fig. 2 is a transverse section taken in the plane indicated by the line 22 of Fig. I, looking toward the'left.

Similar numerals of reference designate corresponding parts in both views of the I drawings.

' Among other elements my novel separator comprises spaced and inclined side frames 1. These side frames 1, together with a hopper 2 that is arranged to discharge in the space between the upper ends of the side frames, are supported by a framework 3. I

In furtherance of my invention I arrange in inclined position between the side frames 1, two

chutes

4 and 5, the contiguous ends of which are spaced apart, as indicated by 6. Also in furtherance of my invention I provide the chute 4 at its lower end with a lip 7 while at the upper end of the chute 5 I provide a flange 8, the latter being of greater depth than the lip 7 in about the proportion illustrated. It will also be observed that the contiguous ends of the straight portions of the

chutes

4 and 5 are arranged in substantially the same inclined plane.

By virtue of the described relative arrangement of the

chutes

4 and 5, it will be observed that when grain is fed into the hopper 2, the same will gravitate down the chute 4. The wheat units being smoother 'mental lower chute 5 King .scribed a supplemental chute 45 which is arranged with its upper portion opposite the space 6, and is provided at its lower end with an upturned lip 7 The scheme of my invention as elaborated is adapted to meet the condition that some of the wheat units will fail to jump across the space 6 and will fall with the oat units and the Kinghead units through the said space 6. Therefore I provide the supplemental chute 4 The wheat units together with the oat and Kinghead units will pass down the said chute 4 and then the operation before described will be repeatedi. 6., the wheat units will jump across to the chute 5, while the oat and Kinghead units will drop through the space between the lip 7 and the flange 8, and will be discharged from the separator on the chute 9 I u ould also have it understood that my separator may be used to advantage in the separation of mustard seed from flax, and water grass and other weed seeds from hay seeds.

It will be apparent from the foregoing that notwithstanding its simplicity and durability, my novel separator is expeditious and thorough in operation.

Having described my invention, what I claim and desire to secure by Letters-Patcut, is:

A grain separator comprising spaced frame sides, a hopper arranged to discharge grain between the upper portions of said frame sides, means supporting the frame sides and the, hopper, an upper inclined chute arranged to receive grain from the hopper and extending in inclined position downwardly between the frame sides and having an upwardly directed lip at its lower end, a lower chute arranged in inclined position between the frame sides and with its upper end below and spaced from the lip at the lower end of the upper chute, a flange reaching upwardly from the upper end of "lower end, a reverseIy-inelined chute in com- 10 the lower chute, 'said flange-being of greater munication with the Space between the lip depth than the lip of the upper chute, a of the fourth-named chute and the thirdchutezirranged between the frame sides 'in -named'chute,iand an upstanding flange arpesition to receive grain from the lower'ef fifnged between and commen to the thirdsaid chutes, 2L chute arranged between the- "named chute and the fifth-named chute. 15 frame sldes 1n positlonto recelve gram from In tQStlIIlOIllX/ whereof I affix Iny slgnature.
