Improvements in Machines for Cleaning and Separating Oats and
other Grain.
I, HAMILTON MICHAEL BARRETT of Castle Mills Ballinasloe Ireland Gentleman
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to the cleansing and separating of oats and the like, and
to apparatus therefor, and has for its object, the construction of a machine for the
combined process of cleansing and separating oats, and the like, by once passing
them through the machine, thus saving both time and labour.
For the purpose of carrying my invention into practice I construct my apparatus
as follows:-
On a main driving shaft of the required dimensions, running in bearings, sup-
ported on suitable uprights or standards, bolted to a firm base, of any suitable
design; a drum is mounted at any required inclization from the horizontal.
This drum I form of steel wire or woven gauze, the meshes of which vary in
fineness at different portions of its lengths. The said drum may be either circular,
hexagonal, or of other suitable form in cross sections but preferably hexagonal.
The steel wire gauze is stretched over and affixed, by any suitable method, to a
framework constructed of any required number of sets of radial arms, affixed to
solid collars or bosses keyed at intervals upon the aforesaid shaft, said radial arms
being connected by horizontal stays extending the whole length of the drum.
Beneath the revolving drum a trough or other convenient receptacle is arranged,
having compartments to correspond with the different divisions of the aforesaid
drum, for receiving the grain and also the foreign matter separated therefrom.
That my invention may be more fully understood, I will now proceed to describe
the same in detail, having reference at the same time to the accompanying drawings
in which;
Fig. 1. is a side elevation of an approved form of my separating and cleansing
machine;
Fig. 2. a portion of the framework of the drum, on an enlarged scale:
Fig. 3. one of the sets of radial arms affixed to a collar which is keyed to the
main axle or shaft ;
Fig. 4. a plan view of one end of the revolving drum and
Fig. 5. a transverse section on a still further enlarged scale, of one of the
horizontal stay rods.
Like letters indicate corresponding parts in all the figures.
a. a. is the main shaft or axle, mounted at any requisite inclination from the
horizontal and running in bearings b. 6' on the standards or uprights c. c'
which standards or uprights with the bedplate D. form the main framing of
the inachine.
On the shaft a. a. is formed a framework consisting of the required number of
solid collars or bosses, in each of which, preferably six radial arms are screwed or
otherwise firmly affixed, as clearly shown in Fig. 3. f. is the collar or boss keyed
to the shaft a. g. g. the radial arms on which solid shoulders h. h. arc
formed; the ends of the radial arms extending beyond the shoulders h. h. are screw-
threaded to receive the nuts .. On the free ends of the radial arms horizontal
stay rods are firmly bolted, as shown in Fig. 2. such stay rods being of the length
required for the finished drum. The horizontal stay rods j. are formed preferably
of the section shown in Fig. 5. in which is a wooden or other rod or lath to
which the semi-circular plate of metal 7. is secured thus forming a protection

page_text: for the stay rod, such semi-circular face being presented on the inside of the
finished drum.
On the framework above described, which may be of any requisite dimensions,
gauze, preferably constructed of woven steel wire or other like material, of varying
degrees of fineness best adapted for the purpose required, is firmly affixed by nails,
or some other suitable method or means.
I prefer to divide the drum into four divisions or sections A. B. C. D. beneath
which is a receptacle or trough, divided as represented by the dotted lines mmm²
into a corresponding number of compartments A'B'C'D'. The said divisions
or sections of the drum range in the fineness of the meshes, from fine at A to
coarse at D.
The ends of the drum are formed of plates of the form shown in Fig. 4. which
plates are affixed by means of bolts or the like, at nnn to the ends of the
horizontal stay rods,
j.
The ction of my machine is as follows:-
The oats or other grain to be cleansed and separated, is introduced by any con-
venient method or means, through the orifice O. (Fig. 4) directly into section A. of
the reiving drum and while in this section all fine impurities i.e. dust &c. are
extraced the gauze covering being too fine to pass other matter through its meshes.
In section B. Blacks, seeds and other foreign matter of a coarser nature are dealt
with and extracted.
Section C. separates the smaller oats, and section D. the large clean oats from
all other impuri.ies such as nails, stones, bits of iron, wire, straw and the like,
which might possibly escape section B.
It is obvious of the above description I may make slight alterations, in the form
and construction of my machine without necessarily departing from the nature of
my said invention. The machine may be made of any suitable dimensions and
materials according to requirements.
I propose naming my separator "Die Reinigkeiter" for distinctive purposes.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
1. In a cleaner and separator for grain, a revolving drum rotatably mounted and
driven by any convenient power, said drum being divided into sections substantially
as and for the purposes herein specified.
2. In a machine as herein above described, the framework of the drum, con-
sisting of radial arms and horizontal stay rods covered with wire gauze or the
like all constructed substantially as herein set forth and illustrated and for the
purposes specified.
Dated this 15th day of December 1891.
