IMPROVEMENTS IN THE STRAW SHAKING
Year: 1873

page_text: LETTERS PATENT to James Marshall, Henry Dickenson Marshall,
and Charles Marshall, all of Gainsborough, in the County of
Lincoln, for the Invention of "IMPROVEMENTS IN THE STRAW SHAKING
Scaled the 20th June 1873, and dated the 18th February 1873.
PROVISIONAL SPECIFICATION left by the said James Marshall,
Henry Dickenson Marshall, and Charles Marshall at the Office of
the Commissioners of Patents, with their Petition, on the 18th
February 1873.
We, JAMES MARSHALL, HENRY DICKENSON MARSHALL, & CHARLES
MARSHALL, all of Gainsborough, in the County of Lincoln, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE STRAW
SHAKING APPARATUS OF THRASHING MACHINES," to be as follows :-
Our improvements in the straw shaking apparatus of thrashing
machines, relate first, to the introduction of a number of tips to shake
the straw, and pass it along from the thrashing drum in lieu of the longi-
tudinal boxes or other appliances now generally used for this purpose.
These tips are made either rectangular, circular, or of any other suitable

page_text: form on their upper surface, which may be found most convenient in
practice, they are lathed or otherwise covered with small spaces left
between, and are made of sufficient width to suit the inside of the
machine frame, being suspended upon a bar with bearings at each end,
working in brasses, wood blocks, or iron bushes attached to the frame
side. Motion is imparted to these tips by means of springs or other
mechanical appliances connected with the usual dressing shoes as used
in thrashing machines, one end of such springs or appliances being
connected to the tips, and the opposite end to the dressing shoes, the
reciprocating motion of the latter imparting an oscillating motion to the
tips. According to the position in which the springs or appliances are
attached to the tips, and the angle of same to the dressing shoes any
requisite amount of oscillation can be obtained for the tips. Boards aro
placed edgeway between the tips in order to prevent the straw from
falling between them.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Marshall, Henry Dickenson Marshall, and
Charles Marshall in the Great Seal Patent Office on the 18th August
1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, James
MARSHALL, HENRY D. MARSHALL, and CHARLES MARSHALL, all of
Gainsborough, in the County of Lincoln, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of February, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said James Marshall, Henry D. Marshall, and
Charles Marshall, Her special license that we, the said James Marshall,
Henry D. Marshall, and Charles Marshall, our exccutors, administrators,
and assigns, or such others as we, the said James Marshall, Henry D.
Marshall, and Charles Marshall, 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 expressed,
should and lawfully might make, usc, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,

page_text: and Isle of Man, an Invention for "IMPROVEMENTS IN THE STRAW SHAKING
APPARATUS OF THRASHING MACHINES," upon the condition (amongst others)
that we, the said James Marshall, Henry D. Marshall, and Charles
Marshall, our exécutors or administrators, by an instrument in writing
under our or their hands and seals, or under the hand and seal of one of
us or them, 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 James Marshall, Henry D.
Marshall, and Charles Marshall, 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 :-
Our improvements in the straw shaking apparatus of thrashing
machines relate, first, to the introduction of a number of tips a, a, a, as
represented in the Drawing hereunto annexed, to shake the straw and
pass it along from the thrashing drum b in lieu of the longitudinal boxes
or other appliances now generally used for this purpose. The tips a, a,
are made either rectangular, circular, or of any other suitable form on
their upper surface, as may be found most convenient in practice. They
are lathed with laths a¹, a¹, or otherwise covered small spaces being left
between the laths a¹, a¹, and the tips a, a, are made of sufficient width to
suit the inside of the machino frame, being suspended upon a bar with
axes and bearings c, c, at each end working in brasses, wood blocks, or
iron bushes, attached to the frame side. Motion is imparted to these tips
by means of springs d, d, or other suitable mechanical appliances con-
nected with the usual dressing shoes as used in thrashing machines, one
end of such springs d, d, or other appliances being connected to the tips,
and the opposite end to the dressing shoes c, e, the reciprocating motion
of the latter imparting an oscillating motion to the tips a, a. According
to the position in which the springs d, d, or other equivalent appliances
are attached to the tips, and the angle of same to the dressing shoes e, e;
any requisite amount of oscillation can be imparted to the tips a, a
Boards ffare placed edgeway between the tips a, a, in order to prevent
the straw from falling between them.
Having thus described the nature of our improvements, and the

page_text: it understood that we do. not. confine ourselves to the exact details horcin
described, as the same may be varied without departing from the spirit
or character of our Invention, but what we claim is the application of
the tips a, a, or their equivalents to tho straw shaking apparatus of
thrashing machines, substantially as and for the purpose herein-before
described and shewn in the Drawings hereunto annexed.
In witness whereof, we, the said James Marshall, Henry D.
Marshall, and Charlos Marshall, have hereunto set our hands and
seals, this Fifteenth day of August, in the year of our Lord One
thousand eight hundred and seventy-three.
