Brye, Minnewaukan, N. Dak. Application March 8, 1937, Serial No. 129,741 1 Claim. This invention relates to seed separators and has for the primary object the provision of a device of this character which may be success fully employed for separating different kinds of (Cl. 209-95) which the seeds collect during‘ the operation of 5 seeds, thereby eliminating the necessity of hav ing to employ a different machine or separator for each kind of seed, which is now the practice and which requires a large ?nancial outlay be sides requiring an excessive amount of space for H O the accommodation of such machines or sepa rators. Another object of the invention is the provision of a machine of the above stated character which is so constructed as to permit separator units 15 designed for different kinds of seeds to be easily and quickly adapted to or removed from the ma chine, so that one machine can be readily con verted for use in separating different kinds of 20 seeds. With these and other objects in view, this in vention 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 my invention, 25 reference is to be had to the following descrip tion and accompanying drawing, in which Figure 1 is an end View partly in section illus trating a seed separator constructed in accord 30 ance with my invention. Figure 2 is a vertical sectional View illustrat ing the means of removably mounting a sepa rator unit on the machine. Figure 3 is a fragmentary vertical sectional 35 view illustrating one means for removably se curing the separator unit on the machine. Figure 4 is a fragmentary vertical sectional view illustrating one of the ends of the separator unit. Referring in detail to the drawing, the nu meral 1 indicates a frame of a seed separator in cluding supporting rollers 2 on which is mounted for rotation a separator unit support 3 including a cylinder 4 equipped at its ends with bearing 45 sleeves 5 grooved to receive the rollers 2 and each includes a ?ange 6 provided with screw threaded apertures to receive stud bolts 1. During the use of the machine for the purpose of separating the seeds the cylinder 4 is rotated by the rollers 2, the latter being driven in any well known manner and forms no part of the present invention. Operating within the cylinder 4 is a separator the machine for delivery into a conveyor In. In order that this machine may successfully sepa rate different kinds of seeds it is the primary ob ject to provide separator units designed for the different kinds of seeds and in order that these different separator units may be employed in one machine a removable connecting means is pro vided between the cylinder 4 and the separator unit and consists of a pair of annular heads ll 10 arranged at each end of the sleeve and each equipped with apertured ears l2 to receive the stud bolts 1 whereby the heads are detachably connected to the cylinder 4. Eachhead also in cludes a bearing portion l3 in the form of a 15 sleeve, the end of which is beveled to form a seat 14. The ends of the separator units are also beveled to match the seats l4. Thus it will be seen that the heads II will ef?cientlysupport a separator unit within the cylinder 4 for rotation 20' therewith. By tightening the stud bolts 1 a fric tional drive is provided between the heads and the separator unit and as the heads rotate with the cylinder 4 the separator unit is consequently required to rotate with the cylinder 4. Whenever it is desired to change a separator unit it is only necessary to detach theheads from the cylinder 4 and withdraw the separator unit from the cyl inder and another separator unit designed for another kind of seed may be readily placed in 30 the cylinder 4 and connected thereto by the heads ll. - With reference to the foregoing and the ac companying drawing it will be seen that a sepa rator of this kind by having separator units for 35 every kind of seed can be at any time easily con verted for separating seeds of a selected kind, thereby eliminating the present practice of em ploying complete separating machines for each kind of seed which materially reduces the cost 40 ~ of seed separation. Having described the invention, I claim: , In a seed separator, a cylinder, bearing sleeves mounted on the cylinder at the ends thereof to contact a supporting means and including 45 ?anges having screw threaded openings, a sepa rator cylinder having beveled ends received in the ?rst named cylinder, annular heads having beveled ends to engage the beveled ends of said separator cylinder, ?anges formed on the heads 50 and arranged exteriorly of the ?rst named cyl inder and paralleling the ?anges of said sleeves, and stud bolts extending through the ?anges of unit 8 which may be of any well known con the heads and threaded in the screw threaded struction and in this instance is in the form of a cylinder having a plurality of sumps 9 in openings of the ?anges of said bearing sleeves.
