This Invention has for its object the construction or arrangement of new or
improved apparatus for cleansing barley or grain, and separating broken barley,
grain or dross therefrom in such a manner that such operation is performed more
conveniently speedily and effectually than is possible at the present time.
In carrying out the Invention according to one modification of the new or
improved apparatus there are two cylinders of a suitable length placed side by
side, at an inclination, that is having one end lower than the other. The cylinders
may be geared together so as to turn in opposite directions and they may be hollow
but their peripheries are formed preferably principally of wood. These wooden
cylinders are covered with perforated zinc or other suitable material and holes are
made in the outsides of the wooden cylinders to correspond with the perforations
in the zinc. The holes are of a depth about equal to the diameter of the perforations
in the zinc and the perforations are of such a size that when barley or grain is
passed over the surface of the cylinders the whole or unbroken grain does not enter
and remain in the holes but gradually falls as the cylinders revolve towards the
lowermost ends of the cylinders whilst the broken grain fine seeds dust or dross,
fall into the holes and are retained therein until by the continued revolution of the
cylinders the broken grain and dross is discharged at the sides of the machine.
By the continued action of the machine the whole and cleaned grain will be
discharged at the lower most end of the machine and the broken grain and dross
will be discharged at the sides of the apparatus. In some cases only one cylinder
may be found necessary, and if found preferable the zinc may be dispensed with
and the cylinder (or cylinders) be formed of iron having suitable holes formed in
its surface.
In another modification of the new or improved apparatus instead of the
perforated zinc being put over cylinders it may be placed over flat wooden or
other suitable surfaces (or iron plates having suitable holes may be used.) Tue

I, WILLIAM BONE of 3 Fern Terrace, New Somerby, Grantham, Lincolnshire,
Agricultural Machinist, do hereby declare the nature of my said Invention for
A NEW OR IMPROVED APPARATUS FOR CLEANSING BARLEY OR ORAIN, AND
SEPARATING BROKEN GRAIN OR DROSS THEREFROM," and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement that is to say :—
My Bnid Invention has for its object the construction or arrangement of new or
improved apparatus for cleansing barley or grain and separating broken barley,
grain or dross therefrom in such a manner that such operation is performed. moro
conveniently, speedily and effectually than is possible at the present time.
In carrying out my said Invention according to ono modification of the new or
improved apparatus there are two cylindors of a suitable length placed side by side
at an inclination, that is, having one and lower than the other. The cylinders are
geared together so as to turn in opposite directions, and they may bo hollow but
their peripheries are formed preferably principally of wood. Those wooden cylinders
are covered with perforated zine or other suitable metal and cavities are made in
the outsides of the wooden or other cylinders to correspond to the perforations in
the metal cover. These cavities are of a depth about equal to the diamotor of tho
perforations in the metal cover which perforations are of such a size that when the
barley or grain is passed over the surface of the cylinders the whole or. unbroken
grain onters the cavities but does not remain thero. The perfect grain being too
large to remain in the cavities falls by its weight towards the lower ends of the
cylinders as they revolve whilst the imperfect or broken grain, dirt, heraph, fiue

page_text: seeds or dross, fall into the cavities and remain therein until by the revolution of
the cylinders the cavities are brought underneath and the broken grain and dross
is discharged at the sides of the machine. The whole and cleaned grain will by
the action of the machine be discharged into suitable-receptacles at the lower ends
of the cylinders, whilst the dross and dirt will be discharged on to the ground or
into a receptacle. In some cases only one cylinder may be found necessary and the
zine may be dispensed with, the cylinder or cylinders being formed of iron or other
suitable metal with suitable boles or cavities formed in the surface.
In another modification of the new or improved apparatus instead of using
cylinders the perforated zine may be placed over flat wooden or other suitable
surfaces having suitable cavities in them, or iron or other metal plates having the
cavities in them may be used. These plates may be connected together so as to
form an endless band which is arranged at a suitable angle so that the perfect or
unbroken corn will fall off whilst the dross and broken grain will be retained in
the cavities until discharged by the turning of the plates round end rollers, when
the dross falls to the ground or into suitable-receptacles.
In another modification perforations are made through a wooden board, or metal
plate which is caused to revolve horizontally on a vertical shaft over a plane surface
so that the grain cannot fall through the perforations. A strike is arranged to
knock off the unbroken grain as the plate revolves, just before the grain reaches
part in the plane surface beneath where there is a narrow alit or opening through
which slit the dross and broken grain falls into any suitable receptacle.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to and representing the preferable modification of my new or
improved apparatus. In these drawings the same reference numerals are used. to
mark the saine or like parts wherever they are repeated.
Figure 1 on the accompanying sheet of drawings is a sectional side elevation of
any improved apparatus, and Figure 2 is a plan whilst Figure 3 is a cross section
showing certain parts of the apparatus to be hereinafter described and Figure 4 is
a plan of the parts shown in Figure 3. In the new or improved apparatus there
are arranged side by side two cylinders 1, 2 of a suitable length to suit the size of
the machine required. These cylinders are formed principally of wood (but may
be of metal) and have small cavities 3 or holes formed close together all over in
their surfaces, which will be best seen on referring to Figures 3 and 4. These
cylinders 1, 2 are covered with perforated zinc, the perforations in which are of a
size sufficient to allow of fine seed and broken grain to pass through but are not
large enough to admit a whole or unbroken grain to pass lengthwise, and the
cavities in the wooden cylinders are of a depth about equal to the diameter of
the perforations in the zinc which perforations coincide with the cavities in
the cylinders. These parallel cylinders 1, 2 have trunnions at their ends which are
carried in suitable bearings formed for them at each end of a rectangular frame 4.
This frame is fitted at an incline within a casing or framing 5 of the machine,
with its lower end at a short distance from the ground thus carrying and
supporting the two cylinders in an inclined position. This frame 4, also carries
two metal troughs or channels 6 one at each side and between the cylinders above
them there is fixed to the frame 4 a bar 7 square or nearly so.in section. This
bar 7 is placed with one of its angles projecting downwards between the cylinders,
so that its two lower sides are only just clear of the cylinders thus preventing any
grain passing between. The troughs or channels 6, are also placed so that their
inner sides, at each side are inclined towards the cylinders which their upper edges
just clear, being close enough to prevent any whole grain passing between them
when the cylinders revolve. The sides of the channels 6 nearest the cylinders form
approximately a tangent to the circle of the cylinders and the perfect or unbroken
grain falls into these channels at each side, when the cylinders revolve whilst, the
dirt, broken grain and fine seeds or dross contained in the cavities can pass the
upper edges of the channels 0 and fall from the cylinder as the cavities are brought

page_text: underneath by the revolution of the cylinders on to the ground or into a receptacle.
The grain to be operated on is placed in a hopper 8, carried by the framing 5, at
the higher end of the inclined cylinders 1, 2, and on opening a small sliding door 9,
the grain falls on to the cylinders. To ensure the passage of the grain through the
machine the frame 4, has a jigging motion imparted to it and consequently to the
cylinders and parts it carries. To produce this jigging motion there is arranged
near the middle of the machine underneath the frame 4 a short shaft 10, having a
pulley 11, for a driving belt (or chain gearing) 12 on its outer end, the pulley 11,
being outside the framing 5, and has motion given to it from a pulley 13, titted
above near the higher end of the framing 5. The inner end of the shaft 10, has a
crank which is connected by a rod 14, to the upper end of the frame 4 at its middle.
By this means a jigging motion is given to the frame 4 and the parts it carries tho
frame being fitted to slide in the framing 5, and this motion assists the grain in
passing downwards over the cylindors and down the channels 6 until it is. dis-
charged by an opening 15, having a shute at each side. This pulley 13 is carried
by a short shaft having on it a second and smaller pulley 10, and an crank handle 17
for turning by hand (or it may be otherwise turned). A driving belt 18, (or it may
be a chain) is passed over this pulley 16, and over guide pulleys 19, fixed on a
vertical shaft 20, carried in bearings at the corner of the framing 5, thence the
belt 18, is passed round a pulley 21, on the upper end of the cylinder 1. By
turning the handle 17, a jigging motion is given to the frame 4, and at the same
time the cylinder 1, is turned whilst by means of a twisted driving belt passed
round a small pulley 22, on the end of the cylinder 1, and round a similar pulloy 23,
on the end of the cylinder 2, the cylinder 2, is caused to revolve in an opposite
direction to the other cylinder. It is obvious that instead of the belt the cylinders
may be geared together by toothed wheels fitted at their ends.
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) The combination and arrangement of apparatus for cleansing grain substan-
tially as herein before described with reference to the accompanying drawings.
(2) The employment of plane or cylindrical surfaces having a number of suitable
small cavities formed in them close together, substantially as and for the purposes
herein before described.
