AN IMPROVED ARRANGEMENT OF MACHINERY FOR DRESSING GRAIN
Year: 1857

page_text: LETTERS PATENT to Joseph Ruston and James Toyne Proctor, of
Lincoln, Engineers, for the Invention of "AN IMPROVED ARRANGEMENT
OF MACHINERY FOR DRESSING GRAIN."
Sealed the 25th May 1858, and dated the 26th November 1857.
PROVISIONAL SPECIFICATION left by the said Joseph Ruston and James
Toyne Proctor at the Office of the Commissioners of Patents, with their
Petition, on the 26th November 1857.
We, JOSEPH RUSTON and JAMES TOYNE PROCTOR, of Lincoln, Engineers, do
hereby declare the nature of the said Invention for "AN IMPROVED ARRANGE-
MENT OF MACHINERY POR DRESSING GRAIN," to be as follows:-
In dressing grain where a humeller or horner is used, the humeller blades,
the screen brushes, and the blades of the fan are mounted upon separate
spindles, each of which requires driving gear.
Now, our improved arrangement of machinery for dressing grain consists in
mounting the bumeller blades, the brushes which work inside the screen, and.
the fan blades, on one and the same shaft, the shaft being carried through the
humeller case, the screen, and the case in which the fan revolves. The grain
enters the humeller case, is carried forward therein, and delivered into the
screen to be acted upon by the brushes; the grain falls from the screen into
riddles, and the blast from the fan is brought to bear thereon.

by the said Joseph Ruston and James Toyne Proctor in the Great
Soal Patent Office on the 26th May 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPII
RUSTON and JAMES TOYNE PROCTOR, of Lincoln, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of November, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Joseph Ruston and James Toyne Proctor, Her special licence,
that we, the said Joseph Ruston and James Toyne Proctor, our executors,
administrators, and assigns, or such others as we, the said Joseph Ruston and
James Toyne Proctor, our executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein oxpressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, au Invention for "AN IMPROVED
ARRANGEMENT OF MACHINERY FOR DRESSING GRAIN," upon the condition (amongst
others) that we, the said Joseph Ruston and James Toyne Proctor, or one of
us, our executors or administrators, by an instrument in writing under our, or
their, or one of our or their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that we, the said Joseph Ruston and James Toyne
Proctor, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement thereof, reference being had to the
Drawing hereunto annexed, that is to say :—
In dressing grain where a humeller or horner, and a screen with brushes
working inside, as well as a fan, are used, the humeller blades, the screen
brushes, and the blades of the fan are mounted upon separate spindles, each of
which requires separate driving gear.
Now, our improved arrangement of machinery for dressing grain consists in
mounting the humeller blades, the brushes which work inside the screen, and
the fan blades on one and the same shaft, the shaft being carried through the
humeller case, the screen, and the case in which the fan revolves. The grain

page_text: enters the humeller case, is carried forward therein, and delivered into the
screen to be acted upon by the brushes; the grain then falls from the screen,
and the blast from the fan is brought to bear thereon.
In the Drawing hereunto annexed we illustrate in section the manner in
which our improved arrangement of machinery is constructed.
A is the shaft passing through the humeller or horner B, the screen C, and
the fan box D; E, E, are the humeller blades; F is a frame carrying the
brushes a, a; and G are the fan blades, all of which are mounted on the
shaft A; H is a pulley on the same shaft round which a strap I passes to
communicate motion thereto. Grain enters the humeller mouth B', passes
into the screen C, where it is subjected to the action of the brushes a, a, from
whence it falls and is acted on by the blast from the fan G. The blast from
this fan G will be turned at right angles or otherwise, as may be required.
Although we show the screen cylindrical, we do not limit ourselves to that
form, as it may be formed with tapering sides.
And having now described the nature of our said Invention, and in what
nanner the same is to be performed, we declare that we claim, as our improved
arrangement of machinery for dressing grain, the mounting of the humeller
blades, the brushes which work inside the screen, and the fan blades, on one
and the same shaft, the said shaft being carried through the humeller case,
the screen, and the case in which the fan revolves.
In witness whereof, we, the said Joseph Ruston and James Toyne
Proctor, have hereunto set our hands and seals, this Twenty-fifth day
of May, One thousand eight hundred and fifty-eight.
