IMPROVEMENTS IN OR APPLICABLE TO PROVISIONAL SPECIFICATION
Year: 1874

page_text: LETTERS PATENT to Henry Tasker, of Waterloo Iron Works, near
Andover, in the County of Hants, Agricultural Implement Manu-
facturer, and Henry Shackler, of the same Place, Commercial
Traveller, for the Invention of "IMPROVEMENTS IN OR APPLICABLE TO
PROVISIONAL SPECIFICATION left by the said Henry Tasker and
Henry Shackler at the Office of the Commissioners of Patents,
with their Petition, on the 17th June 1874.
WC, HENRY TASKER, of Waterloo Iron Works, near Andover, in the
County of Hants, Agricultural Implement Manufacturer, and HENRY
SHACKLER, of the same Place, Commercial Traveller, do hereby declare
the nature of our said Invention for "IMPROVEMENTS IN OR APPLICABLE TO
THRASHING MACHINES, AND IN THE APPARATUS CONNECTED THEREWITH," to be as
follows:-
This Invention relating to improvements in thrashing machines is
designed for the prevention of the accidents which frequently occur in

page_text: connection with the feeding the produce to be thrashed into the drum of
the machine. The Invention is also intended to prevent the loss of
grain which frequently takes place in feeding the grain to the drum.
Our Invention consists of a series of square or other rolls placed in
such a position with relation to the drum of the thrashing machine
as that when the produce to be thrashed is placed upon them, and the
rolls are rotated, the produce will be carried into the drum, so preventing
all risk of accident to the attendants feeding the machines, and at the
same time preventing loss of grain which frequently occurs, when the
produce is fed directly into the drum by the attendant. The same
objects may be effected by an arrangement of endless bands or chains
carrying boards or sheets.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Tasker and Henry Shackler in the Great
Scal Patent Office on the 16th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
TASKER, of Waterloo Iron Works, near Andover, in the County of
Hants, Agricultural Implement Manufacturer, and HENRY SHACKLER,
of the same Place, Commercial Traveller, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of June, in the year
of our Lord One thousand eight hundred and seventy-four, in the 37th
year of Her reign, did for Herself, Her heirs, and successors, give and
grant unto us, the said Henry Tasker and Henry Shackler, Her
special license that we, the said Henry Tasker and Henry Shackler, our
executors, administrators, and assigns, or such others as we, the said
Henry Tasker and Henry Shackler, our exccutors, administrators, or
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 OR APPLICABLE TO THRESHING
MACHINES, AND IN THE APPARATUS CONNECTED THEREWITH," upon the condition
(amongst others) that we, the said Henry Tasker and Henry Shackler,

page_text: our executors and administrators, by an instrument in writing under our
hands and scals, or under the hand and seal of one of us, should par-
ticularly 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 Henry Tasker and Henry
Shackler, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, reference being had
to the accompanying Drawings and to the letters and figures marked
thereon, that is to say :-
Our said Invention relating to improvements in threshing machines
is designed for the prevention of the accidents which frequently occur in
connection with the feeding the produce to be threshed into the drum of
the machine. The Invention is also intended to prevent the loss of
grain which frequently takes place in feeding the grain to the drum.
Our Invention consists of a series of square or other shaped rolls placed
in such a position with relation to the drum the of threshing machine, as
that when the produce to be threshed is placed upon them and the rolls
are rotated the produce will be carried into the drum, so preventing all
risk of accident to the attendants feeding the machines, and at the
same time preventing loss of grain which frequently occurs when the
produce is fed directly into the drum by the attendant.
And in order that our said Invention may be fully understood we
shall now proceed more particularly to describe the same and for that
purpose shall refer to the several Figures ou the annexed Sheet of
Drawings, the same letters of reference indicating corresponding parts
in both the Figures.
Figure 1 represents a side elevation of a portion of a threshing machine,
shewing one mode of carrying out our Invention, and Figure 2 is a longi-
tudinal section of same..
A is the drum of the machine between which and the breastwork B
the produce is to be introduced; C, C, are a series of rolls shewn square
in the Drawing, but which may be of any other suitable form, which
rolls are mounted on spindles a supported in bearings in the frame of
the machine and are connected together by spur wheels D, shewn in red

page_text: lines in Figure 1, so as to be capable of rotating conjointly when
actuated from the driving shaft of the machine or by other suitable
means; E is a hinged cover for guarding against accidents by persons
falling on to the drum or on to the feeder, and also for preventing the
loss of grain by its flying from the drum. In supplying the produce to
the drum the attendant who is stationed in a box F places the produce
over the first of the series of rolls C, C, which by its rotation conveys the
same on to the next roll, whence it is conducted in succession by their
rotation along the whole series of rolls until it finally falls on to the
drum A. An inclined plane G is provided for the purpose of conducting
on to the drum any grain which may accidentally fall between the rolls.
In some cases it may be desirable in order to further separate the
produce to employ an additional roll H, provided or not with teeth or
projections, such roll being caused to rotate in the opposite direction 'to
the rolls C, C, and made capable of adjustment nearer to or further
from the latter so as to suit the crops.
Having now described and particularly ascertained the nature of
our said Invention and the manner in which the same is or may be used
or carried into effect, we would observe in conclusion that what we
consider to be novel and original and therefore claim as the Invention
secured to us by the herein-before in part recited Letters Patent is,
the application and use to and with threshing machines of a series of
rotatory rolls for the purpose of feeding the produce on to the drum of
the machine, substantially as herein-before described and illustrated by
our Drawings.
In witness whereof, we, the said Henry Tasker and Henry
Shackler, have to this our Specification set our hands and seals,
this Fourteenth day of December, One thousand eight hundred
