Lincoln, Machine Maker, for the Invention of "IMPROVEMENTS IN
STRAW SHAKERS OF THRASHING MACHINES," bearing date the Twenty-
eighth day of September One thousand eight hundred and fifty-five,
and which said Letters Patent, and all interest therein, have been
duly assigned to and are now vested in Nathaniel Clayton, Joseph
Shuttleworth, and Charles Seely, trading under the style or firm of
Clayton, Shuttleworth, and Company," of the City of Lincoln,
Ironfounders and Agricultural Implement Makers and Machine
Manufacturers.
SCLAIMER proposed to be entered by the said Nathaniel Clayton, Joseph
Shuttleworth, and Charles Seely, as such Assignees as aforesaid, pursuant
to the Statutes in that case made and provided.
WHEREAS doubts have been raised whether that part of the Invention
ich was claimed in the words following:-"And, third, giving such a motion
to the shaker bars or shaker boxes forming the straw shaker, that the said
shaker bars or shaker boxes are made to cross one another in working, or
hat the plane of the faces of such parts, if prolonged from the direction of
he centre of vibration, would cross one another during its work," is new,

the said Specification.
In witness whereof, we, the said Nathaniel Clayton, Joseph Shuttle-
worth, and Charles Seely, have hereunto set our hands and seals, this
Sixth day of June, in the year of our Lord One thousand eight
and sixty one
I hereby grant my fiat, giving leave to the aforesaid Nathaniel Clayton,

for the Invention of "IMPROVEMENTS IN STRAW SHAKERS OF THRASHING
MACHINES."
Sealed the 8th January 1856, and dated the 28th September 1855.
PROVISIONAL SPECIFICATION left by the said James Good at the Office of
the Commissioners of Patents, with his Petition, on the 28th September
1855.
I, JAMES GOOD, of the City of Lincoln, Machine Maker, do hereby declare
the nature of the Invention for "IMPROVEMENTS IN STRAW SHAKERS OF THRASHING
MACHINES" to be as follows:-
This Invention consists in suspending or supporting the shaker bars or
shaker boxes, forming the straw shaker, by radial links, applied either alter-
nately or otherwise, at opposite ends of the shaker bars or boxes, and in giving
motion to the said shaker bars or boxes by a cranked axle or cranked axles,
applied to the shaker bars or boxes at points intermediate of their points of
support or suspension.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Good in the Great Seal Patent Office on the 20th
March 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
GOOD, of the City of Lincoln, Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of September, in the year of our
Lord One thousand eight hundred and fifty-five, in the nineteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said James Good, Her special licence that I, the said James Good,
my executors, administrators, and assigns, or such others as I, the said James
Good, 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 "IMPROVEMENTS IN STRAW
SHAKERS OF THRASHING MACHINES," upon the condition (amongst others) that
I, the said James Good, my executors or administrators, by an instrument in
writing under my, or their, or one of 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 I, the said James Good, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention consists in suspending or supporting the shaker bars or
shaker boxes, forming the straw shaker, either alternately or otherwise at
opposite ends of the shaker bars or boxes, and in giving motion to the said
shaker bars or boxes by a cranked axle or cranked axles, applied to the shaker
bars or boxes at points intermediate of their points of support or suspension.
Having thus stated the nature of my Invention, I will proceed to describe
more fully the manner of performing the same.
The Drawing hereunto annexed represents a longitudinal section and end
elevation of so much of a thrashing machine as will enable me readily to
describe the improvement applied to the straw shaker of a thrashing machine
according to my present Invention.

page_text: The shaker boxes A, A, B, B, are alternate, and are suspended at opposite
ends; those marked A, A, being suspended at the end by the radius rods C, C,
and those marked B, B being carried at the opposite ends by the links marked
D, D. The cranked shaft or axis F, by which motion is given to the shaker
boxes, is placed between the centres of suspension, and consequently, in this
arrangement between the extreme points of vibration. It will be seen, that
when the shaft F is put in motion, the straw is shaken and tossed throughout
the whole length of the shaker, instead of, as in the old plan, for only a portion
of the length. Thus, as in the Drawing, if the cranked shaft F be put in
motion the shaker boxes A, A, rise and receive the straw, shaking it with
more than the full throw of the crank, until it arrives in the middle, or at the
point immediately over the crank, when it is taken on by the boxes B, B,
and the throw is again increased until the straw is thrown from the machine.
During the revolution of the crank axle, the inclination of the face of the
shaker boxes is continually changing, both as due to the radial movement
in respect to a horizontal position, but also with respect to one another, the
boxes A, A, crossing the boxes B, B.
Having now described the nature of my Invention, and in what manner
the same is to be performed, I would have it understood that I claim,--
First, suspending the shaker bars or shaker boxes forming the straw shaker
either alternately or otherwise at opposite ends.
Second, communicating motion to the shaker bars or shaker boxes forming
the straw shaker at a point between the said centres of suspension, or between
the extreme points of vibration.
And, third, giving such a motion to the shaker bars or shaker boxes
forming the straw shaker, that the said shaker bars or shaker boxes are
made to cross one another in working, or that the plane of the faces of
such parts, if prolonged from the direction of the centre of vibration, would
cross one another during its work.
In witness whereof, I, the said James Good, have hereunto set my hand
and seal, this Seventh day of March, One thousand eight hundred
Witness,
WILLIAM WALLER, of Lincoln.
JAMES GOOD. (L.S.)
