Improvements in Machines known as Oat or Barley Clippers for
Treating Oats and similar Grain.
.
I, HENRY PLEWMAN HANNON, of Ardreigh House, Athy, Ireland, Corn Miller,
do hereby declare the nature of this invention to be as follows:-
The object of the invention is an improvement in machines for performing
what is known as the operation of clipping outs and similar grain, this is,
removing a portion of the beard and improving the appearance of the grain by
polishing.
The invention consists mainly of a machine on the principle of an under run
shelling stone, in which the oats are first passed through between a pair of
concave & convex specially prepared surfaces and afterwards scoured against
a cylindrical wire case by adjustable beaters.
In
The horizontal fixed & running surfaces which operate on the oats and other
corn are provided with a large number of minute conical excrescences.
passing between these surfaces the beard of the oats is removed or loosened and
the operation completed in the lower portion of the machine into which the outs
fall immediately after passing through the conical surfaces. This machine can
also be combined in the ordinary manner with a dusting sieve applied to the oats
before coming into the special machine, and followed by another sieve and an
aspiration so as to thoroughly cleanse the oats and separate from them the endings
or removed particles of beard.

Improvements in Machines known as Oat or Barley Clippers for
Treating Oats and similar Grain,
1, HENRY PLEWMAN HANNON, of Ardreigh House, Athy, Ireland, Corn Miller,
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 machines for clipping or removing part of the beard
of oats or similar grain and for improving the appearance of the grain by
polishing and cleaning it.
A machine constructed according to these improvements is provided with an
upper fixed concave surface and a lower rotary convex surface, and each of these
surfaces is formed with a large number of inwardly projecting minute points or
protuberances. The grain first passes between the surfaces and has its beard
removed or loosened. It then falls into a lower cylindrical wire casing or cylin-

page_text: drical sieve in contact with which it is cleansed or scoured by rotary beaters, or
blades and brushes.
In order that my invention may be more readily understood I have hereto
appended a sheet of drawings to which I will refer hereinafter.
Figure 1 illustrates the improved machine in vertical section.
Figure 2 is a representation of part of the machine in sectional plan.
At the upper part of the machine is fixed a plate A which is concave or
hollowed on its lower face. Beneath this and secured to the shaft B is a second
plate C which is correspondingly convex or conical on its upper face. The inner
or opposing faces of the plates are furnished with a great number of minute
protuberances or projections. The plates may conveniently be formed of thin
sheet metal punched from the back, as in a nutmeg.grater, and secured to a
timber framing or backing by screws or the like.
The grain, to be treated is fed into a hopper 1) and passes into the space
between the two plates A and C. Upon the rotation of the latter plate the grain
has its beard removed or loosened by the action of the protuberances or points
and passes through the conical space, finally escaping and falling over and around
the edge of the plate C.
The falling grain is then cleansed or scoured against a cylindrical cage or
sieve E by means of beaters or blades, and brushes or the like, which are also
secured to the shaft B and rotate with it.
Either beaters or brushes alone may be used, but a combination of the two,
as illustrated, will be found generally convenient. Blades F are secured to the
leading ends of the arms of the spiders or spokes G. They may be fastened in
place by bolts, set screws or the like H, which pass through slots in the blades so
that the latter may be set at any required distance from the sieve E' Brushes J
are secured to the following ends of the arms, and may be carried by angle
plates K which are also fastened by bolts passing through slots so that the
brushes may be adjusted relatively to the sieve. If desired the leading edge
of the brush may be further away from the sieve than the following edge."
The treated grain is led to one side of the apparatus by means of a sweep,
blade, or the like secured to the shaft B and falls into a shoot L whence it is
discharged.
A casing M may surround the cylindrical sieve E so as to form a chamber
for the reception of the removed beards and the like, and may be exhausted in
any suitable manner:
The lower end of the shaft B rests upon a screw N by means of which the
distance between the plates A and C may be regulated.
The grain, before being treated in the described machine may be dusted in a
dusting sieve, and may pass after treatment into another sieve where it may be
aspirated, and these different sieves may be combined so as to work in con-
junction with each other.
The shaft B instead of being driven by the pulley P' near its upper end, may
be otherwise rotated, as for example by means of a similar pulley near its lower
end, by toothed gearing or otherwise.
In substitution for the punched sheet metal herein before described the inner
opposing, faces of the plates A and C may be covered with woven wire cloth made.
from wire having a square or other suitable section.
Either or both of the plates A and C or those parts carrying the abrading
surfaces may be secured in place by set screws or the like, so that perfect adjust-
ment may be effected and parallelism ensured between the opposed surfaces:"
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
1 claim is:-
1. In a machine for clipping oats and similar grain, concave and convex or
conoidal plates the inner faces of which are provided with a number of minute

page_text: points or protuberances, constructed and arranged substantially as herein before
described and as illustrated by the accompanying drawings.
2. A machine for clipping oats and similar grain, constructed and arranged
substantially as herein before described and as illustrated by the accompanying
drawings.
