IMPROVEMENTS IN PORTABLE AND FIXED COMBINED THRASHING, SHAKING,
Year: 1854

page_text: LETTERS PATENT to Nathaniel Clayton and Joseph Shuttleworth, Agri-
cultural Engineers, of Stamp End Iron Works, Lincoln, for the Invention
of "IMPROVEMENTS IN PORTABLE AND FIXED COMBINED THRASHING, SHAKING,
PROVISIONAL SPECIFICATION left by the said Nathaniel Clayton and
Joseph Shuttleworth at the Office of the Commissioners of Patents, with
their Petition, on the 20th June 1854.
We, NATHANIEL CLAYTON and JOSEPH SHUTTLEWORTH, Agricultural Engi-
neers, of Stamp End Iron Works, Lincoln, do hereby declare the nature of
the Invention for "IMPROVEMENTS IN PORTABLE AND FIXED COMBINED THRASHING,
SHAKING, AND WINNOWING MACHINES," to be as follows:-
This Invention consists of a peculiar combination and construction of
mechanical parts of a combined thrashing, shaking, and winnowing machine.
For this purpose the blower is divided, so as to make two blowers on the
same spindle, and the lower riddle and hoppers are divided, and dress the
grain twice over without increasing the moving parts of the machine. The
blades of the beater of the thrashing drum are each made with grooved or
undulating edges, the grooves or undulations being inclined or diagonally across
the edges of the beaters.

by the said Nathaniel Clayton and Joseph Shuttleworth in the Great Scal
Patent Office on the 20th December 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, NATHANIEL
CLAYTON and JOSEPH SHUTTLEWORTH, Agricultural Engineers, of Stamp End
Iron Works, Lincoln, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of June, in the year of our Lord One
thousand cight hundred and fifty-four, in the eighteenth 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 exccutors, administra-
tors, 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
PORTABLE AND FIXED COMBINED THRASHING, SHAKING, AND WINNOWING MACHINES,'
upon the condition (amongst others) that we, the said Nathaniel Clayton and
Joseph Shuttleworth, by an instrument in writing under our hands and seals,
or under the hand and scal of one of us, should particularly describe and
ascertain the nature of the said Invention, and in what manner the samo
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 consists of a peculiar combination and construction of
mechanical parts of a combined thrashing, shaking, and winnowing machine.
For this purpose the blower is divided, so as to make two blowers on the same
spindle, and the lower riddle and hoppers are divided, and dress the grain twice
over without increasing the moving parts of the machine. The blades of the
beater of the thrashing drum are each made with grooved or undulating edges,
the grooves or undulations being inclined or diagonally across the edges of the
beaters.

page_text: DESCRIPTION OF THE DRAWING.
Figure 1 is a longitudinal section; Figure 2 is a plan, partly in section;
Figure 3 is an end view of the corn shaker; and Figure 4 is an end view of
blowers. These improvements consist in forming two blowers or fanners on
one spindle, and in dividing the hopper, formed under first riddle for conveying
the grain to the second riddle, in such a manner as to enable two riddles to be
formed upon one frame (side by side), as shewn in Figure 2. The position of
lower riddles are indicated by the red lines in Figure 2. The operation of twice
riddling and once blowing is performed in the usual manner; but instead of
being then put into the sack it is lifted into the horner, passing through that
part of the machine which is not shewn; is then passed into the aperture A,
shewn in Figure 2, and then riddled once more and blown; after which it is put
into sacks in the usual way, and is ready for the market.
The two lower riddles, though on the same frame, are divided from each
other, and are therefore in two different compartments, which do not com-
municate with each other; the corn from the upper riddle falls through the
opening on to one of the lower riddles, and then, having passed through the
horner, it passes down through the opening A on to the second lower riddle B,
and is there blown by the second blower, and is then received into sacks. In
constructing the beaters of thrashing machines, we prefer that the beaters
should be grooved or undulating in place of plain, but we make no claim
thereto, that having before be done; what we claim is, the applying two
blowing fans or blowers on the same axis, and dividing the lower riddle into
two separate compartments, in such manner that the corn may be a second
time dressed, as herein described.
In witness whereof, we, the said Nathaniel Clayton and Joseph Shuttleworth,
have hereunto set our hands and seals, this Nineteenth day of December,
in the year of our Lord One thousand eight hundred and fifty-four.
Witness,
