page_text: LETTERS PATENT to Nathaniel Clayton and Joseph Shuttleworth,
of Lincoln, in the County of Lincoln, Engineers, for the Invention
' of "IMPROVEMENTS IN THE FRAMES OF PORTABLE COMBINED THRASHING AND
WINNOWING MACHINES."
.
Sealed the 28th March 1871, and dated the 21st January 1871..
PROVISIONAL SPECIFICATION left by the said Nathaniel Clayton and
Joseph Shuttleworth at the Office of the Commissioners of Patents, .
with their Petition, on the 21st January 1871.
We, NATHANIEL CLAYTON and JOSEPH SHUTTLEWORTH, of Lincoln,
in the County of Lincoln, Engineers, do hereby declare the nature of
our said Invention for "IMPROVEMENTS IN THE FRAMES OF PORTABLE COMBINED
THRASHING AND WINNOWING MACHINES," to be as follows :-
This Invention consists in the mode of construction of the frames of
portable combined thrashing and winnowing machines, whereby such
frames are converted into trusses on the same principle as the trussed
frames of roofs and bridges. By this construction the whole strain or
weight is thrown by means of diagonal struts upon the bearing points
or travelling wheels, thereby bringing the bottom sill into the condition

page_text: of a tie beam, the strain produced from the weight of the machine being
only in the direction of its length.
It will further be seen that by reducing the length of the upright
frame and diagonal strut and screwing up the bottom sill thereto by
bolts, an arched form of frame may be produced, thus preventing
deflection, which is an inherent evil in all frames of this class hitherto
constructed.
This mode of construction ensures greater strength and is much less
liable to injury from travelling on bad and uneven roads, consequently
the efficient working of the machines is less liable to be affected.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Nathaniel Clayton and Josephi Shuttleworth in the
Great Seal Patent Office on the 20th July 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, NATHANIEL
CLAYTON and JOSEPH SHUTTLEWORTH, of Lincoln, in the County of
Lincoln, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of January, in the
year of our Lord One thousand eight hundred and seventy-one, in
the 34th year of Her reign, did, for Herself, Her heirs and successors,
give and grant.unto us, the said Nathaniel Clayton and Joseph Shuttle-
worth, Her special license that we, the said Nathaniel Clayton and
Joseph Shuttleworth, our executors, administrators, and assigns, or such
others as we, the said Nathaniel Clayton and Joseph Shuttleworth, our
executors, administrators, or 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 THE FRAMES OF PORTABLE COMBINED THRASHING AND WINNOWING MACHINES,"
upon the condition (amongst others) that we, the said Nathaniel Clayton
and Joseph Shuttleworth, by an instrument in writing under our hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed,

page_text: 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 Nathaniel Clayton and Joseph
Shuttleworth, do hereby declare the nature of our said Invention, and
in what manner the same is to be performed; to be particularly described
.and ascertained in and by the following statement, reference being had
to the Drawings hereunto annexed, and to the letters and figures marked
thereon (that is to say):
Our said Invention consists in the mode of construction of the frames
of portable combined thrashing and winnowing machines, whereby such
frames are converted into trusses on the same principle as the trussed
frames of roofs and bridges.
The accompanying Drawing, represents a thrashing machine frame.
constructed according to our Invention.
By this construction of frame the whole strain or weight is thrown
by means of the diagonal struts A upon the bearing points or travelling
wheels, thereby bringing the bottom sill B into the condition of a tic
beam, the strain produced from the weight of the machine being only
in the direction of its length.
It will further be seen that by reducing the length of the upright
frame C and strut D, and screwing up the bottom sill B thereto by the
bolts E, a slightly arched form or frame may be produced, the dotted
line in the Drawing indicating the horizontal, thus preventing deflec-
tion, which is an inherent evil in all frames of this class hitherto
constructed.
This mode of construction ensures greater strength and is much less
liable to injury from travelling on bad and uneven roads, consequently
the efficient working of the machines is less liable to be affected..
We would here observe that we prefer English oak as the material to
be employed for the construction of the frames, but iron or a combination
of wood and iron may be employed for that purpose.
Having now described and particularly ascertained the nature of our
said Invention, and the manner in which the same is or may be used or
carried into effect, we would observe in conclusion that what we consider
to be novel and original, and therefore claim as the Invention secured
to us by the hercin-before in part recited Letters Patent is, the

page_text: constructing of the frames of portable, combined thrashing and winnow-
ing machines, in such a manner that they shall form trussed frames and
shall throw the entire strain or weight of the machine on to the two
bearing points, substantially as herein-before described.

In witness, whereof, we, the said Nathaniel Clayton, and Joseph
Shuttleworth, have to this our Specification set our hands and
seals, the Seventeenth day of July One thousand eight hundred
and seventy-one.
