A COMBINED THRESHING AND STacking MACHINE
Year: 1872

page_text: LETTERS PATENT to Stephen Lewin, of Poolé, in the County of
Dorset, for the Invention of "A COMBINED THRESHING AND STacking
MACHINE."
Sealed the 11th March 1873, and dated the 27th September 1872.
PROVISIONAL SPECIFICATION left by the said Stephen Lewin at the
Office of the Commissioners of Patents, with his Petition, on the
27th September 1872.
I, STEPHEN LEWIN, of Poole, in the County of Dorset, do hereby
declare the nature of the said Invention for "A COMBINED THRESHING AND
STACKING MACHINE," to be as follows :—
"
When corn is threshed and the straw is stacked on the field, it is
usual to place near together a threshing machine and an elevator or
stacking machine, and to work both by engine or other power, so that
the straw as it is delivered from the threshing machine is raised to the
stack by the elevator, but as the threshing machine and the elevator are
separate machines it is often inconvenient to draw them and place them

page_text: in position, as well as to connect them with the prime mover, and each
necessarily has its own carriage and travelling wheels on which it is
moved from place to place.
Now the object of my Invention is the construction and arrangement
of a combined threshing and stacking machine on one framing and one
set of travelling wheels, both driven by one belt or other mechanical
connection from the prime mover, so that when the threshing machine
is drawn to the field and placed in position and connected to the prime
mover, the clevator or stacking machine is at the same time brought
with it and made ready for use, and when the threshing machine is put
to work the straw delivered from its shakers is at once raised by the
elevator to the stack. For this purpose, at the delivery end of the
threshing machine I mount on a horizontal axis the framing of the
elevator, so that it can be made to project therefrom in an inclined
position like the jib of a crane, the inclination being adjustable so as
to suit varying heights of the stack, and I connect a wheel or pulley
on the driving shaft of the elevator by gearing or a band to a wheel
or pulley on one of the revolving shafts of the threshing machine,
speeding the elevator suitably to the discharge of straw from the
threshing machine.
I make the framing of the elevator jib with a folding joint, in such a
manner that when the apparatus is not in use the framing can be folded
over the top of the threshing machine, and the whole can then be
conveniently moved from place to place.
It is obvious that an elevator may be attached in the manner and for
the purpose above described to any threshing machine of known con-
struction. A convenient form of elevator for being so attached is onc
constructed in a manner somewhat similar to that described in the
Specification of a Patent granted to me on the 27th of January 1870,
No. 242, the carriage and wheels of such elevator being dispensed with,
and the framing of its jib being made with a joint so that it can be
folded over the threshing machine, thereby rendering the combined
apparatus conveniently portable as described above.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Stephen Lewin in the Great Seal Patent Office on
the 25th March 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, STEPHEN
LEWIN, of Poole, in the County of Dorset, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of September, in
the year of our Lord One thousand eight hundred and seventy-two, in
the thirty-sixth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Stephen Lewin, Her special
license, that I, the said Stephen Lewin, my executors, administrators,
and assigns, or such others as I, the said Stephen Lewin, 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 "A COMBINED
THRESHING AND STACKING MACHINE," upon the condition (amongst others)
that I, the said Stephen Lewin, 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 Stephen Lewin, 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, reference being had to the accompanying
Sheet of Drawings, and to the figures and letters marked thereon, that
is to say:
When corn is threshed and the straw is stacked on the field, it is
usual to place near together a threshing machine and an elevator or
stacking machine, and to work both by engine or other power, so that

page_text: the straw as it is delivered from the threshing machine is raised to the
stack by the elevator, but as the threshing machine and the elevator are
separate machines it is often inconvenient to draw them and place them
in position, as well as to connect them with the prime mover, and cach
necessarily has its own carriage and travelling wheels on which it is
moved from place to place.
Now the object of my Invention is the construction and arrangement
of a combined threshing and stacking machine on one framing and one
set of travelling wheels, both driven by one belt or other mechanical
connection from the prime mover, so that when the threshing machine
is drawn to the field and placed in position and connected to the prime
mover, the elevator or stacking machine is at the same time brought
with it and made ready for use, and when the threshing machine is put
to work the straw delivered from its shakers is at once raised by the
elevator to the stack. For this purpose, at the delivery end of the
threshing machine I mount on a horizontal axis the framing of the
elevator, so that it can be made to project therefrom in an inclined
position like the jib of a crane, the inclination being adjustable so as
to suit varying heights of the stack, and I connect a wheel or pulley
on the driving shaft of the clevator by gearing, or a band to a wheel
or pulley on one of the revolving shafts of the threshing machine,
speeding the clevator suitably to the discharge of straw from the
threshing machine.
I make the framing of the elevator jib with a folding joint, in such a
manner that when the apparatus is not in use the framing can be folded
over the top of the threshing machine, and the whole can then be
conveniently moved from place to place.
It is obvious that an elevator may be attached in the manner and
for the purpose above described to any threshing machine of known
construction. A convenient form of elevator for being so attached is
one constructed in a manner somewhat similar to that described in the
Specification of a Patent granted to me on the 27th of January 1870,
No. 242, the carriage and wheels of such elevator being dispensed with,
and the framing of its jib being made with a joint so that it can be
folded over the threshing machine, thereby rendering the combined
apparatus conveniently portable, as described above.

page_text: DESCRIPTION OF THE DRAWING.
The Figure on the accompanying Sheet of Drawing represents a side
view of part of a threshing machine of any known construction with a
straw elevator combined with it according to my Invention.
A is part of the threshing machine to which is fixed a step B forming
a support for the lower end of the clevator which is mounted thereon,
with a joint C permitting it to swing in a vertical plane to any required
inclination. The elevator is supported near its upper end from a jib D
mounted on the top of the threshing machine, and provided with
gearing D', so that it can be raised or lowered by means of a winch
handle. Such gearing may be like that of an ordinary crab, the pinion
of which works a toothed arc fixed to the jib, or such a toothed arc may
be geared directly with a worm worked by hand. By the action of this
gearing the jib D may be raised or lowered so as to bring the upper end
of the elevator to a convenient position for delivering the straw upon
the stack S. As the jib D and the elevator work on different centres,
the suspending hook D of the jib is arranged to run along guides on the
clevator frame to allow for the eccentricity of motion.
The frame of the elevator is made with a joint at E, so that when
it is not in use it can be folded over the threshing machine, and thus
it can be more conveniently moved therewith from place to place and
accommodated under cover. The moving parts of the elevator may be
constructed in any known manner. They are put in motion from the
shaft F at the lower end of the clevator, this shaft being driven either
by gearing or a strap from any suitable revolving part of the threshing
machine, so that when the latter is in operation the elevator is also put
to work.
The straw delivered from the shakers or other discharging part of the
threshing machine at G falls into a hopper H provided at the lower
end of the elevator, whence it is carried upwards by the elevator and
delivered at top on to the stack.
Having thus described the nature of my Invention, and in what
manner the same is to be performed, I would have it understood that
I make no claim to any special construction of threshing machine, nor
5 to any special construction or use of clevator for raising straw to a

page_text: stack, when taken separately, nor do I claim generally the combination
of a threshing machine with a straw elevator; but I claim, the com-
bination, substantially as herein described, of a straw clevator with a
threshing machine, the elevator being supported on and extending as a
jib from the threshing machine, and jointed so that the two apparatus
can be moved and placed and made to operate together.
In witness whereof, I, the said Stephen Lewin, have hereunto
set my hand and seal, this Twenty-first day of March, in the
year of our Lord One thousand eight hundred and seventy-
three.
