1 Claim.

This invention relates to grain separators, and has for the primary object the provision of a device of this character which is in the form of an attachment easily adaptable to an elevator of a grain thresher or similar device for receiving therefrom grains of different kinds and which will efficiently and economically separate the different grains from each other and deliver the separated grains for bagging and other modes v of collection and which is driven by power derived from the elevator and may be manufactured and sold at a low cost.

With these and other objects in view, the invention consists in certain novel features of con- 'struction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of our invention, reference is to be had to the following description and accompanying drawings, in

which I Figure l is a bottom plan view partly in section illustrating a grain separator constructed in accordance with our invention and showing the application thereof to an elevator.

Figure 2 is a vertical sectional View illustrating the device.

Figure 3 is a sectional view taken on the line 3--3 of Figure 2.

Figure 4 is a transverse sectional view taken on the line 4-4 of Figure 2.

Figure 5 is a fragmentary plan View illustrating a riddle cleaner.

Figure 6 is a fragmentary end elevation illustrating a portion of one end of the riddle and a portion of one end of a pan.

Referring in detail to the drawings, the numeral 5 indicates a housing of elongated formation and gradually increasing in size toward one end and the largest end thereof is provided with a grain receiving opening 6 adjacent the top wall. The grain receiving opening is arranged in communication with a discharge opening of a grain elevator l which may form a part of a threshing machine or similar device (not shown). The elevator 1 includes the usual endless conveyor 8 having buckets a thereon which empty as they reach the upper end of the elevator and deposit the grain for passing into the housing 5 or into an inclined platform ill provided in the housing and projecting slightly into the elevator.

Extending from the top wall of the housing adjacent the opening 6 and above the platform is a deflector plate II to deflect grain on the platform as it is discharged by the buckets of the elevator and also acts to distribute the grain over said platform so that on leaving the latter it will fall onto riddle t2 arranged in the easing 5 for reciprocation and disposed at a slight 5 inclination. The riddle inclines downwardly from the receiving end of the housing and is pivotally supported by links it pivoted on walls of the housing and to the riddle. Carried by and underlying the riddle is a pan M to receive grain 10 which passes through the riddle and inclines in a direction opposite to the inclination of said riddle and discharges into a hopper I5 located at one end of the housing. The hopper is equipped with diverging discharge spouts l6. 15

At the opposite end of the housing is a hopper H to receive grain which passes from the lower end of the riddle and is provided with diverging discharge spouts [8.

The riddle 12 consists of a frame i9 closed by 20 a screen 20, the mesh of which may be of any desired gauge depending on the character of seeds that are to be separated. The uppermost end of the frame 19 has connecting links 2! piv-- oted thereto which extend through slots 23 in 25 the end wall of the housing 5 and are journaled on cranks 24 of a crank shaft 25 supported by journals 26 at one end of said housing 5. The crank shaft has secured thereto a sprocket gear 27 over which is trained an endless sprocket 30 chain 28 which in turn passes about a sprocket gear 29 secured on the uppermost shaft 3i) of the conveyor 8 of the elevator i, so that when the conveyor of the elevator is in operation the ridle 12 will receive a reciprocal motion. 35

A clearer frame 3! is arranged directly under the riddle frame 59 and spaced therefrom and carries relatively spaced transversely arranged supporting bars 32 on which are secured strips of fibre such as belting, felt or any other suit- 40 able material. The strips are indicated by the character 33 and the upper edges thereof rub against the screen 2i] for the purpose of maintaining the screen clean during the use of the device. The screen 259 rubs over the cleaning ele- 4 ments 33 during the reciprocation of the riddle and as the cleaning construction of the device is of skeleton formation seeds passing through the screen 26 may readily pass through the cleaner onto the bottom Wall of the casing for 50 gravitation into the hopper if.

It is preferable that one of the side walls of the housing 5 be equipped with'a door at which may be readily opened to give inspection to the riddle while in operation or to permit the easy removal of the riddle of the housing when desiring to change for another wherein the screen will be of a different gauge mesh.

In operation, the different kinds of grain discharged from the elevator 1 are received on the platform Ill and gravitate therefrom onto the riddle, the larger seeds passing off the lower end of the riddle into the hopper I 1 while the smaller grain or seeds pass through the screen onto the pan l4 and gravitate therefrom into the hopper l5, thereby bringing about a quick and efficient separation of grain or seeds of different kinds.

It is a common practice to grow within a field difierent kinds of seeds or grain such as oats and peas and to thresh them simultaneously. When this threshing operation is carried on the present invention or separator as heretofore described and shown in the drawings .Wlill efficiently separate the peas from the oats, the peas passing into the hopper I1 while the oats pass into the hopper l5. The different kinds of grains or seeds from their respective hoppers can be easily bagged or otherwise collected from the chutes of said hoppers.

It is believed that the foregoing description, when taken in connection with the drawings will fully set forth the construction and advane tages of this invention to those skilled in the art to which such a device relates so that further detailed description will not be required.

What we claim is:

In a grain separator, a housing having the bottom thereof open and provided with a grain receiving opening in one end thereof and adjacent the top Wall of said housing to admit grain from a thresher, an inclined platform supported by said housing and extending inwardly thereof from the grain receiving opening, hoppers mounted in the open portion of the housing and each including discharge means, a pan slidably supported by the hoppers and inclined toward one of said hoppers at one end thereof the pan and secured on the housing.
