I, GODFREY SAMUEL Down of Brusna Cottage Roserea in the county of Tipperary
Ireland, Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in machinery for bearding scouring
and polishing grain, and has for its object to provide a machine for breaking the
rootlets off dried malt, and for scouring cleaning and polishing malt, grain, and
similar substances.
According to my invention the grain is fed down a shoot and delivered upon or
between a pair of horizontal cylindrical brushes, adapted to rotate in opposing
directions towards each other. The brushes are enclosed in a casing, and their axes
are mounted in bearings conveniently situated outside the casing. One or more pairs
of such brushes may be similarly mounted vertically below the first pair. The brushes
are placed horizontally at such distance apart that the surfaces of each pair are in
contact, and one of each pair is made adjustable horizontally in the usual manner so
that the required pressure may always be secured. The surfaces may be formed of
strong bristles, flexible wire, or other suitable substance.
Each pair may be of the same or different diameters and is caused to revolve at the
same or different speeds as required by suitable driving pulleys, and belts, gearing,
or otherwise. The brushes are entirely enclosed by the casing and suitable guard
plates are provided to direct the grain and prevent it scattering beyond them.
The grain is delivered along the full length of the brushes between the guard
plates and after passing between the brushes falls into a hopper forming part of the
machine, from which it passes to the screen or separator (not forming any part of my
machine), and any known means for separating, grading, sampling, may be employed.
Dated this Sixth day of June 1887.

page_text: I, GODFREY SAMUEL DOWD of Brusna Cottage Roscrea in the County of Tipperary,
Ireland, Manager, 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 certain improvements in machinery for bearding scouring
and polishing grain, and has for its object to provide a machine for breaking the
rootlets off dried malt, and for scouring cleaning and polishing malt, grain, and
similar substances.
My invention is illustrated in the accompanying drawings in which Figure 1 is a
sectional plan of a machine with a single pair of brushes, and Figure 2 is a half end
elevation and half cross section thereof. Figure 3 is an end elevation of a machine
with 2 pairs of brushes, and Figure 4 is a longitudinal section thereof. Like letters
refer to like parts in the figures.
According to my invention the grain to be treated is fed down a shoot of any
convenient form into the hopper h and delivered upon or between a pair of horizontal
cylindrical brushes a a¹ adapted to rotate in opposing directions towards each other.
The brushes a a' are enclosed in a casing c, which may be of wood or metal or partly
of wood and partly of metal, and their axes are mounted in suitable bearings e e¹
conveniently situated outside the casing c. One or more pairs of such brushes may
be similarly mounted below the first pair, a second such pair bb is illustrated in
figures 3 and 4.
The brushes are placed horizontally in pairs at such distances apart that the
surfaces of each pair are in contact, and one of each pair a' in the figures is
preferably made adjustable horizontally by means of sliding bearings ef and
operating screws s's which may be of usual construction, but I prefer to employ solid
brasses in one peice bored out for the axles of the brushes as illustrated and with a.
feather on upper and lower sides of the adjustable brass and adapted to slide in a
groove of corresponding shape in the metal guide frame, the upper and lower parts
of which are made of suitable length and are bolted together at the ends.
A spring of suitable strength may be interposed between the sliding brasses and
screws so that any hard substance passing into the brushes will cause the moveable
brush to recede automatically from the other and thus avoid liability of breakage of
any of the parts of the machine or driving gear; thus the required pressure of the
brushes upon each other may always be secured. The surfaces of the brushes may be
formed of strong bristles, a mixture of whalebone and cane, flexible wire, or other
suitable substance or substances. Each pair may be of the same or different
diameters and each may be driven but it is advantageous to drive the fixed or non-
adjustable one only by a suitable driving pulley p upon its axle through belting or by
other suitable means.

page_text: In the single machine illustrated in figures 1 and 2 one brush a only is supposed to
be driven its fellow brush a' may be caused to rotate at the same speed simply by
the friction of their surfaces in contact, but the fellow brush may be driven either by
crossed belting or by simple spur gearing of same diameter and pitch as indicated
by the broken line figure 2 and illustrated at g g' in figure 3. The teeth of these
wheels g g are made long and of suitable pattern so as to allow of the adjustment of
the moveable brush a¹ and the smooth working of the pair. Such crossed belting or
gearing may be provided at one or both ends of the brushes as required. Different
velocities may be obtained when desired by suitably proportioning such gear wheels
or other medium employed. In a double pair machine such as illustrated in figures 3
and 4 the gear may be arranged as shown the lower pair of brushes bb being driven
by one of the upper pair a through an intermediate pinion. When a greater amount
of travel is desired for the adjustable brush than is obtainable efficiently by simple
spur gearing the brush wheels may be arranged out of gear with each other and a
pair of pinions introduced gearing with each other and with the brush wheels: in
this case when 2 pairs of brushes are employed to avoid complication the lower pair
may be driven on intermediate pinion arranged at the other end of the machine as
illustrated in figure 3.
The brushes whether there be one two or more pairs are entirely enclosed by the
wood or metal casing c and suitable guard plates d d forming the base of hopper h at
either side and at the ends if desired are provided to direct the grain and prevent it
scattering beyond the brushes. A sliding plate and hand wheel may be provided to
adjust the opening at base of hopper / as required as illustrated at d¹ figure 2. The
grain is delivered along the whole length of the brushes between the guard plates d d
and after passing between the brushes falls into a hopper a from which it passes to
the screen or separator (not forming any part of my machine) and any known means
for separating grading, sampling may be employed.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
1. In machinery for bearding, scouring, and polishing grain, the arrangement of
one or more pairs of horizontal cylindrical brushes beneath a feed hopper cach such
pair being caused to rotate in opposing directions towards each other with their
surfaces in contact and capable of horizontal adjustment the brushes being enclosed
in a casing and arranged substantially as and for the purposes set forth.
2. The use in combination of the improved arrangement of brushes in pairs and
gear for driving and adjusting same substantially as and for the purposes hereinbefore
described and illustrated by the drawings.
