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
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
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
For a complete understanding of my invention,
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
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
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.
