Year: 1857

page_text: LETTERS PATENT to William Wood Pilcher, of St. Margaret's, at Cliffe;
Dover, for the Invention of "IMPROVEMENTS IN STRAW SHAKERS OF THRASHING
MACHINES."
Sealed the 21st July 1857, and dated the 10th February 1857.
PROVISIONAL SPECIFICATION left by the said William Wood Pilcher
at the Office of the Commissioners of Patents, with his Petition, on the
10th February 1857.
I, WILLIAM WOOD PILCHER, of St. Margaret's, at Cliffe, Dover, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN STRAW SHAKERS
OF THRASHING MACHINES," to be as follows:-
This Invention has for its object improvements in straw shakers of thrashing
machines. For these purposes a series of endless bands or cords are used.
parallel to each other from end to end of the shaker. The endless cords or
bands are kept distended on a series of pullies on axes parallel to each other.
The pullies are fixed excentrically to their respective axes, and the several,
pullies on the same axis are arranged in different directions, so as to bring the
endless ropes or cords successively into action, whilst all the endless ropes or
cords are moved continuously from end to end of the shaker.

....
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WOOD PILCHER, of St. Margarett's, at Cliffe, Dover, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of February, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
"William Wood Pilcher, Her special licence that I, the said William
Wood Pilcher, my executors, administrators, and assigns, or such others
as I, the said William Wood Pilcher, 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 William Wood Pilcher,
my executors or administrators, by an instrument in writing under my, or their,
or one of their hands and scals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, 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 William Wood Pilcher, 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 straw shakers of thrashing
machines. For these purposes à series of endless bands or cords are used
parallel to each other from end to end of the shaker. The endless cords or
Lands are kept distended on a series of pulleys on axes parallel to each other.
The pulleys are fixed excentrically to their respective axes, and the several
pulleys on the same axis are arranged in different directions, so as to bring
the endless ropes or cords successively into action, whilst all the endless ropes
or cords are moved continuously from end to end of the shaker.
Having thus stated the nature of my Invention, and the manner of per-
forming the same, I will now proceed to describe the accompanying Drawing,

page_text: which represents so much of a thrashing machine, having my Invention applied,
as will with the description thereof render the same perfectly intelligible..
Figure 1 is a side elevation, and Figure 2 is a plan. a, a, is a series of
endless bands or cords, or chains may be employed in lieu thereof, parallel
from end to end of the shaker. These bands a, a, are kept distended on series
of pulleys b, b, and c, c, fixed excentrically on axes e and f, in opposite directions
in such manner as to bring the bands a, a, successively into action. The axis e
receives motion from a band g, which passes around the pulley h
of the drum or beater, and around a pulley fixed upon the axis c. The axes e
and fare connected together, and communicate motion the one to the other by
means of the connecting link i attached to arms e', f¹, on the axes e and f, or
the axes e and f may be made to communicate motion to each other only by
the series of bands a, a.
on the axis
In order to allow of the bands a, a, being tightened up after being placed, the
axes e and fare arranged to work in slots provided with suitable tightening
screws, and the connecting link i will also be made in two parts, such parts
being connected with screws working in slots, so as to admit of its length being
adjusted.
Having described the nature of my Invention, and the manner of carrying
the same into practise, I desire it to be understood that I do not confine
myself to the precise details shown; but what I claim, is, the employment of
endless bands arranged on pullies to form straw shakers of thrashing machines,
&c., as herein shown and described.
In witness whereof, I, the said William Wood Pilcher, have hereunto set
my hand and seal, this Tenth day of August, in the year of our Lord
One thousand eight hundred and fifty-seven.
Witness,
FRED HARRIS.
W WOOD PILCHER. (L.S.)
