page_text: LETTERS PATENT. to William Wilkinson and Henry Thompson Wright, of
Boston, in the County of Lincoln, Ironfounders, for the Invention of
"IMPROVEMENTS IN APPARATUS USED WHEN STACKING STRAW AND OTHER
AGRICULTURAL PRODUCE,"
Sealed the 5th March 1861, and dated the 10th September 1860.
PROVISIONAL SPECIFICATION left by the said William Wilkinson and
Henry Thompson Wright at the Office of the Commissioners of Patents,
with their Petition, on the 10th September 1860.
We, WILLIAM WILKINSON and HENRY THOMPSON WRIGHT, of Boston, in the
County of Lincoln, Ironfounders, do hereby declare the nature of the Inven-
tion for "IMPROVEMENTS IN APPARATUS' USED WHEN STACKING STRAW AND OTHER.
AGRICULTURAL PRODUCE," to be as follows:-
This Invention has for its object improvements in apparatus used when.
stacking straw and other agricultural produce. For these purposes endless
chains or ropes are employed, and they are kept, distended between two rollers,.
the necks or axes of the lower one of which rollers turn in suitable bearings
carried by the framing of a thrashing machine when straw is to be raised
therefrom, or such lower roller may have. the bearings of its necks. or axes
carried by any suitable stand or framing. It is preferred, that, the bearings for
the necks or axes of the other or upper roller should be carried by two poles,

page_text: each having a wheel at its lower end, so that by placing a wedge under each
of the wheels the poles may be readily retained at any elevation to which they
may be brought, but other arrangements may be resorted to for supporting the
upper roller. Motion is communicated to the endless chains or ropes by
actuating the lower roller by the same power which drives the thrashing
machine when the elevating machinery is used in combination with a thrashing
machine; or motion may be communicated to the elevating machinery by any
suitable means. It should be understood that no claim is made to the use of
endless chains or ropes for elevating straw and other agricultural produce, in
order to the same being stacked, the peculiar character of our Invention con-
sisting in the combining with such chains or ropes a series or continuous
succession of flexible pockets or concave receivers, into which the straw or
other agricultural produce is received, and by them elevated. These flexible
pockets or concave receivers may be made of strong netting, or other suitable
fabric or material. By thus using a continuous chain or succession of flexible
pockets or receivers as they in successions come up to the upper roller and pass
over it, they become flattened on the roller, by which the pockets or receivers
are turned inside out, and the contents of the flexible pockets or receivers are
emptied in succession, and they then pass down to be again filled.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Wilkinson and Henry Thompson Wright in the
Great Seal Patent Office on the 9th March 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
WILKINSON and HENRY THOMPSON WRIGHT, of Boston, in the County of
Lincoln, Ironfounders, send greeting.
WHEREAS Her most. Excellent Majesty Queen Victoria, by Her. Letters
Patent, bearing date the Tenth day of September, in the year of our Lord,
One thousand eight hundred and sixty; in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
William Wilkinson and Henry Thompson Wright, Her special licence that
we, the said William Wilkinson and Henry Thompson Wright, our executors,
administrators, and assigns, or such others as we, the said William Wilkinson
and Henry Thompson Wright, 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

page_text: and Ireland, the Channel Islands, and Isle of Man, an Invention for "Im-
PROVEMENTS IN APPARATUS USED WHEN STACKING STRAW AND OTHER AGRICULTURAL
PRODUCE," upon the condition (amongst others) that we, the said William
Wilkinson and Henry Thompson Wright, 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 William Wilkinson and Henry
Thompson Wright, 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 apparatus used when
stacking straw and other agricultural produce. For these purposes endless
chains or ropes are employed, and they are kept distended between two
rollers, the necks or axes of the lower one of which rollers turns in suitable
bearings carried by the framing of a thrashing machine when straw is to be
raised therefrom; or such lower roller may have the bearings of its necks or
axes carried by any suitable stand or framing. It is preferred that the
bearings for the necks or axes of the other or upper roller should be carried
by two poles, each having a wheel at its lower end, so that by placing a wedge
under each of the wheels the poles may be readily retained at any elevation to
which they may be brought, but other arrangements may be resorted to for
supporting the upper roller! Motion is communicated to the endless chains
or ropes by actuating the lower roller by the same power which drives the
thrashing machine when the elevating machinery is used in combination with
a thrashing machine; or motion may be communicated to the elevating
machinery by any suitable means. It should be understood that no claim is
made to the use of endless chains or ropes for elevating straw and other
agricultural produce, in order to the same being stacked, the peculiar character
of our. Invention consisting in the combining with such chains or ropes a series
or continuous succession of flexible pockets or concave receivers, into which
the straw or other agricultural produce is received, and by them elevated.
These flexible pockets or concave receivers may be made of strong netting, or
other suitable fabric or material. By thus using a continuous chain or
succession of flexible pockets or receivers as they in succession come up to the
upper roller and pass over it, they become flattened on the roller, by which

page_text: the pockets or receivers are turned inside out, and the contents of the flexible
pockets or receivers are emptied in succession, and they then pass down to be
again-filled.
"
Having thus stated the nature of our Invention, we will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a side view of apparatus constructed according to our
Invention when at work'; Figure 2, part of a plan thereof; and Figure 3, a
side elevation when the apparatus is in a condition to be moved from place
to place.
a, a, is an endless band, which may be so constructed as to admit of being
shortened or lengthened by having moveable sections, to be removed or added,
as the case may be. This endless band is composed of two endless wire. or
other ropes, or it may be chains of any suitable material. These endless ropes
or chains carry a series of flexible pockets or concave receivers b, b, which it is
preferred should be of strong netting, though other flexible fabric or material
may be used in place thereof. This endless band of flexible concave carriers
is kept extended when in use by means of two rollers c and d. The axes of
the lower roller are carried by bearings in a frame e, e, or by a frame attached
to a thrashing machine. The other rollers d are carried by and turn on the
bar which connects the poles f, f, together, the lower ends of such poles being
carried by two wheels g, g. It is preferred that the two poles should each
consist of two or more parts, so as to admit of their being contracted and
extended in length. The parts f', f', of each pole are combined by straps f², f,
which are fixed to the bar f³, and the upper part f' is caused to slide by means
of a wire, rope, cord, or strap i, which at one end is fixed to the lower end of
the part f', and its other end is fixed to the roller g', which receives motion by
a worm on the axis h, which takes into the worm wheel on the axis of the
roller. g. The rope i passes over the pulley j. The parts f', f', of a pole are
retained from sliding by a screw k, which passes through the bar f. The
wheels which carry the poles may be retained in any desired positions by
chocks or wedges placed behind-them, or they may be held to the ground by
a cord or chain l, as is shewn in the Drawing. The endless band is put in
motion by means of the axle m, by means of a band driven from a threshing
machine or other source. This axle, by means of a bevel wheel, gives motion
to the bevil wheel on the axis of the roller or drum c.
Having thus described the nature of our Invention, and the manner of
performing the same, we would have it understood that we make no claim to

page_text: any of the parts separately, and we would state that the peculiarity of our
Invention consists in the use of a series of flexible concave receivers in com-
bination with apparatus for carrying and giving motion thereto, as herein
described.
In witness whereof, we, the said William Wilkinson and Henry Thompson
Wright, have hereunto set our hands and seals, this Fifth day of
March, in the year of our Lord One thousand eight hundred and
sixty-one.
