IMPROVEMENTS IN THRASHING MACHINES
Year: 1863

page_text: LETTERS PATENT to Nathaniel Clayton and Joseph Shuttleworth, of Stamp
End Works, Lincoln, for the Invention of "IMPROVEMENTS IN THRASHING
MACHINES."
Sealed the 21st April 1863, and dated the 29th January 1863.
PROVISIONAL SPECIFICATION left by the said Nathaniel Clayton and
Joseph Shuttleworth at the Office of the Commissioners of Patents, with
his Petition, on the 29th January 1863.
We, NATHANIEL CLAYTON and JOSEPH SHUTTLEWORTH, of Stamp End
Works, Lincoln, do hereby declare the nature of the Invention for "IMPROVE-
MENTS IN THRASHING MACHINES," to be as follows:-
This Invention has for its object "Improvements in Thrashing Machines."
Heretofore various forms of grooved or channeled beaters have been applied*
to the drums of thrashing machines. In some the parallel grooves or channels
have been transversely across the width of the beaters, but inclined to the
edges thereof; in others the parallel grooves or channels have been made:
longitudinally from end to end of the beater. These forms of beaters, so far
as we are informed, have not been capable of completely thrashing out all the

page_text: grains from the ears without injury to the grains, nor has the drum of a
thrashing machine having a set of such beaters affixed thereto been well suited
for thrashing all kinds of grain.
Now, according to our Invention, the grooves or channels are formed
parallel to each other, and longitudinally along the face of each beater, not,
however, in straight lines, as heretofore, but in serpentine lines. It is
preferred that each beater of the drum of a thrashing machine should be
formed with three serpentine grooves; this number is not, however, essential,
às the number of grooves or channels in the face of a beater may be varied.
The whole of the grooves or channels, although they are parallel to each other,
and formed in a longitudinal direction along a beater, do not in consequence
of having parallel sides all pass from end to end of a beater, but only some of
them, whilst others only extend along a comparatively short length of a
beater. The drum of a thrashing machine fitted with beaters such as are
herein described is found not only capable of more effectually removing all
the grains from the ears without injury to the grains, but also of more
advantageously thrashing all kinds of grain.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Nathaniel Clayton and Joseph Shuttleworth in. the Great
Seal Patent Office on the 29th July 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, NATHANIEL
CLAYTON and JOSEPH SHUTTLEWORTH, of Stamp End Works, Lincoln, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of January, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,, the
said Nathaniel Clayton and Joseph Shuttleworth; Her special licence; that we,
the said Nathaniel Clayton and Joseph Shuttleworth, our executors, adminis-
trators, and assigns, or such others as we, the said Nathaniel Clayton and Joseph
Shuttleworth,, 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, 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
.

page_text: THRASHING MACHINES," upon the condition (amongst others) that we, the said
Nathaniel Clayton and Joseph Shuttleworth, our executors 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 Nathaniel Clayton and Joseph Shuttle-
worth, 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 has for its object improvements in thrashing machines.
Heretofore various forms of grooved or channelled beaters have been applied
to the drums of thrashing machines. In some the parallel grooves or channels
have been transversely across the width of the beaters, but inclined to the
edges thereof; in others the parallel grooves or channels have been made
longitudinally from end to end of the beater. These forms of beaters, so far
as we are informed, have not been capable of completely thrashing out all the
grains from the ears without injury to the grains, nor has the drum of a
thrashing machine having a set of such beaters affixed thereto been well
suited for thrashing all kinds of grain.
Now, according to our Invention, the grooves or channels are formed
parallel to each other longitudinally along the face of each beater, not,
however, in straight lines, as heretofore, but in serpentine lines. It is
preferred that each beater of the drum of a thrashing machine should be
formed with three serpentine grooves; this number is not, however, essential,
as the number of grooves or channels in the face of a beater may be varied.
The whole of the grooves or channels, although they are parallel to each other,
and formed in a longitudinal direction along a beater, do not in consequence
of a beater having parallel sides all pass from end to end of a beater, but only
some of them, whilst others only extend along a comparatively short length of
a beater. The drum of a thrashing machine fitted with beaters such as are
herein described is found not only capable of more effectually removing all
the grains from the ears without injury to the grains, but also of more
advantageously thrashing all kinds of grain.
Having thus stated the nature of our Invention, we will proceed more fully
to describe the manner of performing the same.

page_text: DESCRIPTION OF THE DRAWING.
The Drawing represents a plan of a beater of a thrashing machine in which:
there are serpentine grooves or channels running longitudinally along the
beater; these grooves or channels are bounded on either side by ridges, which
divide the grooves or channels one from the other, as shown.
In witness whereof, we, the said Nathaniel Clayton and Joseph Shuttle-
worth, have hereunto set our hands and seals, this Twenty-eighth day
of July, in the year of our Lord One thousand eight hundred and
sixty-three.
