IMPROVEMENTS IN MACHINERY FOR SHAKING STRAW
Year: 1869

page_text: LETTERS PATENT to John Wilson, of Poppleton, in the County of
York, for the Invention of "IMPROVEMENTS IN MACHINERY FOR SHAKING
STRAW"
Sealed the 23rd July 1869, and dated the 26th January 1869.
PROVISIONAL SPECIFICATION left by the said John Wilson at the
Office of the Commissioners of Patents, with his Petition, on the
26th January 1869.
I, JOHN WILSON, of Poppleton, in the County of York, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
FOR SHAKING STRAW," to be as follows:-
This Invention relates to certain improvements in machinery for
shaking straw, and consists of novel arrangements for agitating the sifter
or riddle and giving it a reciprocating or rocking motion necessary for
the falling of the grain on to the delivering board.
The shaker consists of a series of leather bands (with spaces between
each) and cross bands attached to bars at each end of the machine, and
extending from the feeding hopper and drum to the delivering board; it

page_text: is actuated by two hangers or rods suspended vertically within each side
of the machine by means of pivots. These hangers are attached to shoes
formed of iron and containing grooves in which a shaft works provided
with an excentric at each end. The shoes being attached to the
delivering board it is evident that the revolution of the excentrics will
give an oscillating motion to the shoes, hangers, and board, and also to
the leather shaker, alternately slackening and tightening each end, the
shaker being supported midway from the board by uprights, leaving two
divisions of the shaker in a slack position while the machine is at rest..
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Wilson in the Great Seal Patent Office on
the 26th July 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WILSON, of Poppleton, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of January, in the year of our
Lord One thousand eight hundred and sixty-nine, in the thirty-second
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Wilson, Her special licence that I, the
said John Wilson, my executors, administrators, and assigns, or such
others as I, the said John Wilson, 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 MACHINERY FOR SHAKING STRAW,"
upon the condition (amongst others) that I, the said John Wilson, 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 im-
mediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Wilson, do hereby declare
the nature of my said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the
following statement :-
My Invention relates to certain improvements in machinery for
shaking straw, and consists of novel arrangements for agitating the sifter
or riddle and giving it a reciprocating or rocking motion necessary for
the falling of the grain on to the delivering board.
The shaker consists of a series of leather bands (with spaces between
each) and cross bands attached to bars at each end of the machine, and
extending from the feeding hopper and drum to the delivering board; it
is actuated by two hangers or rods suspended vertically within each side
of the machine by means of pivots. These hangers are attached to shoes
formed of iron and containing grooves in which a shaft works provided
with an excentric at each end. The shoes being attached to the
delivering board it is evident that the revolution of the excentrics will
give an oscillating motion to the shoes, hangers, and board, and also to
the leather shaker, alternately slackening and tightening each end, the
shaker being supported midway from the board by uprights, leaving two
divisions of the shaker in a slack position while the machine is at rest.
In order that my said Invention may be completely understood I
annex the accompanying Drawings, in which Fig. 1 shews an internal
side view of the shaker; and Fig. 2 a longitudinal view of the spindle
and excentric bosses which actuate the shaker a, a, Fig. 1, which is
formed of a series of leather bands placed side by side having cross
bands at a', a. The ends of the shaker are attached to bars b, b. c is
one of the hangers, of which there are two, one on each side of the
machine or interior of the thrasher; each of them is fastened to shoes, one
of which is shewn at d, in which a socket e is formed to receive the
excentric boss f on the spindle or working shaft g, Fig. 2. The re-
volution of the spindle causes an oscillating or rocking motion of the
shaker at the centre, alternately tightening and slackening each side or
semi-surface, and thereby effectually shaking the straw. h is the drum,
and i the hopper into which the straw is fed; k, k, are the wooden
hangers, and part of the framework.
Having now described the nature of my said Invention, and the
manner in which the same is to be performed, I would remark that I do
not limit myself to the precise details and configuration of parts which
I have expressed and shewn, as the same may obviously be varied or
modified without departing from the object of the Invention, neither do

page_text: I claim the application to the shaker of the bars b, b, the shoe d, and the
shaft and excentric bosses fand 9, 9, together with the drum h and the
hopper i; but what I claim and desire to be secured to me by the herein
in part recited Letters Patent is, the leather shaker a, a, and the socket e
in the shoe whereby motion is given to the shoes and shakers from the
spindle and excentrics, constituting my improvements in machinery for
shaking straw, substantially as herein specified and shewn.
In witness whereof, I, the said John Wilson, have hereunto set
my hand and seal, this Twenty-sixth day of June, in the year
of our Lord One thousand eight hundred and sixty-nine.
Witness,
FREDERIC THOMPSON,
Poppleton Hall,
