Year: 1854

page_text: LETTERS PATENT to Richard Hornsby, of Spittlegate Iron Works,
Grantham, in the County of Lincoln, for the Invention of "AN IMPROVE-
MENT IN THE STRAW SHAKING APPARATUS OF THRASHING MACHINES."
Sealed the 12th September 1854, and dated the 18th July 1854.
PROVISIONAL SPECIFICATION left by the said Richard Hornsby at tho
Office of the Commissioners of Patents, with his Petition, on the 18th
July 1854.
I, RICHARD HORNSBY, of Spittlegate Iron Works, Grantham, in the County
of Lincoln, do hereby declare the nature of the Invention for "AN IMPROVE-
MENT IN THE STRAW SHAKING APPARATUS OF THRASHING MACHINES" to be as
follows:-
This Invention consists of applying, at intervals, on straw shakers, boards
or surfaces (by preference inclined), rising above the general level of the
shakers; by which, as the straw proceeds towards the back end of the shakers,
it is thrown up and opened out more effectually than if the level of the upper
parts of the shakers was uniform or similar from end to end, and at the same
time grains of corn are prevented flying off.

by the said Richard Hornsby in the Great Seal Patent Office on the
16th January 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
HORNSBY, of Spittlegate Iron Works, Grantham, in the County of Lincoln,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of July, in the year of our Lord One
thousand eight hundred and fifty-four, in the eighteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Richard Hornsby, Her special licence that I, the said Richard Hornsby, my
executors, administrators, and assigns, or such others as I, the said Richard
Hornsby, my 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 expressed, 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, an Invention for "AN IMPROVEMENT IN THE STRAW
SHARING APPARATUS OF THRASHING MACHINES," upon the condition (amongst
others) that I, the said Richard Hornsby, by an instrument in writing under
my hand and seal, 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 I, the said Richard Hornsby, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof.(that is to say) :-
This Invention consists of applying, at intervals, on straw shakers, boards
or surfaces (by preference inclined), rising above the general level of the
shakers; by which, as the straw proceeds towards the back end of the shakers
it is thrown up and opened out more effectually than if the level of the upper
parts of the shakers was uniform or similar from end to end, and at the same
time grains of corn are prevented flying off.
Having thus stated the nature of my said Invention, I will proceed to
describe the manner of performing the same.

page_text: DESCRIPTION OF THE DRAWING.
The Drawing represents a longitudinal section of so much of a thrashing
machine as will enable me readily to describe the improvement applied to the
shaker of a thrashing machine according to my present Invention. The
shaker, shown by the Drawing is arranged to work by being suspended on
links near the ends where the parts of the shaker first receive the straw from
the thrashing drum, and the other ends of the shaker are actuated by cranks,
as was described in the Specification of a former Patent, granted to me on the
Sixteenth day of June, One thousand eight hundred and fifty-four. a, b, show
two parts of the shaker; c is the cranked axis, by which the back ends of
the parts a, b, of a shaker are actuated; e, e, are inclined boards, rising con-
siderably above the ordinary surface of the shaker, so that the straw, in passing
along from the front to the back end of the shaker, has to be thrown over these
boards, and thus receives a greater amount of shaking; these boards at the
same time also tend to stop the grain being thrown off.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that what I claim is tho
application of boards or surfaces e, e, at intervals rising above the general
surface of the shaker of a thrashing machine, as herein described.
In witness whereof, I, the said Richard Hornsby, have hereunto set my
hand and seal, this 15th day of January, in the year of our Lord One
thousand eight hundred and fifty-five.
RICHARD HORNSBY. (L.S.)

RICHARD HORNSBY, jn'.
