page_text: LETTERS PATENT to William Tasker, of Halifax, in the County of York, Patent
Agent, for the Invention of "A NEW OR IMPROVED MACHINE OR APPARATUS
FOR CLEANSING AND PURIFYING GRAIN." A communication from Charles
Antoine Duprez, of Reims, France.
Sealed the 27th February 1877, and dated the 2nd September 1876.
PROVISIONAL SPECIFICATION left by the said William Tasker at the Office
of the Commissioners of Patents on the 2nd September 1876.
WILLIAM TASKER, of Halifax, in the County of York, Patent Agent. "A NEW
OR IMPROVED MACHINE OR APPARATUS FOR CLEANSING AND PURIFYING GRAIN."
A communication from Charles Antoine Dupiez, of Reims, France.
This Invention relates to machinery or apparatus to be employed for decorticating
grain and is specially adapted for the use of brewers.
The apparatus consists of a suitable framework which supports two brushes,
placed. face to face, and having a reciprocatory motion imparted to them, the
motions being opposite cach other. The grain is fed to the brushes, by a hopper,
which is also provided with a breaker or crusher and a valve to regulate the supply.
Below the brushes is placed a double sieve, the first cloth of which allows the grain
to pass and retains the larger impurities The second retains the grain and allows
the smaller impurities and dust to pass through. The sieve is agitated by cam or
eccentric suitably arranged.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Tasker in the Great Seal Patent Office on the 2nd March
1877.
WILLIAM TASKER, of Halifax, in the County of York, Patent Agent "A NEW
OR IMPROVED MACHINE OR APPARATUS FOR CLEANSING AND PURIFYING GRAIN."
A communication from Charles Antoine Duprez, of Reims, France.
This Invention relates to machinery or apparatus to be employed for cleansing
and purifying grain, and is specially adapted for the use of brewers.

page_text: The apparatus consists of suitable framework which supports two or more
brushes placed face to face, and having a reciprocatory motion imparted to them
in opposite directions. The grain is fed to the brushes by a hopper, which may
contain a breaker or crusher and a valve to regulate the supply. Below the
brushes is placed a double sieve, the first cloth of which allows the grain to pass
and retains the larger impurities; the second retains the grain and allows the
smaller impurities and dust to pass through. The sieve is agitated by cam or
eccentric suitably arranged.
In order that my Invention may be more fully understood, I herein give reference
to the accompanying Sheet of Drawings, representing a machine of double con-
struction or with two pairs of brushes.
A is the framework; B are the brushes mounted in guides a in the enclosed
boxes or chambers C. These brushes are connected by rods D to eccentrics E,
actuated by shaft F in such manner that each pair of brushes reciprocate in
opposite directions. The grain is fed to the hoppers G and passes through the
conical part H to the centre of the brushes between which it gravitates and finally
falls into the sieve J, having been subjected to considerable fiiction in its passage
through the brushes by which it is perfectly freed from "spiouts" and other im-
purities. The sieve has a rapid oscillatory or jerking motion imparted to it by the
crank K which effects a thorough separation of the grain and refuse, the former
eventually passing out at the opening L which may be facilitated by inclining the
sieve.
This machine satisfies a want which has long been felt, as the apparatus hitherto
employed for this purpose has been very defective
It will be readily seen that the brushes may be disposed or arranged in various
ways, and may work either vertically or horizontally with equal success. The
brushes may also be circular and work in opposite directions at their points of
contact.
The bristles of the brushes may be of any of the substances commonly used, such
as logs' bristles, animal or vegetable fibres, broom, whalebone, or wire.
Having thus described the nature of my said Invention, and shewn by Drawings
how the same is to be or may be performed or carried into practice, I would have
it understood that I claim as my Invention, the employment of brushes working in
close contact or face to face, in manner and for the purpose herein shewn and
described or any mere modification thereof
In witness whereof, I, the said William Tasker, have hereunto set my hand
and seal, this Twenty-eighth day of February, in the year of our Lord
One thousand eight hundred and seventy-seven.
