IMPROVEMENTS IN THRASHING MACHINES
Year: 1874

page_text: LETTERS PATENT to John Day, Engineer to the Reading Iron Works,
Limited, of Reading, in the County of Berks, for the Invention of
"IMPROVEMENTS IN THRASHING MACHINES."
Scaled the 2nd October 1874, and dated the 8th April 1874.
PROVISIONAL SPECIFICATION left by the said John Day at the
Office of the Commissioners of Patents, with his Petition, on the
8th April 1874.
I, JOHN DAY, Engineer to the Reading Iron Works, Limited, of
Reading, in the County of Berks do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THRASHING MACHINES," to be as
follows:-
This Invention relates to improvements in thrashing machines worked
by animals or other motive power, being especially applicable to the type
of iron thrashing machines for which a Patent was granted to W. Exall,
dated 8th March 1848, No. 12,080, and manufactured by Barrett, Exall,
& Andrews, of Reading, whether such machines be worked by animal or
other motive power, whereby the corn is separated from the straw and

page_text: cavings" without the use of a straw shaker, and is also partially
cleaned. These objects are attained by means of a blower attached to
and worked from the machine which separates the "cavings," and an
open platform formed of bars of wood or other material by which the
straw is conveyed away separately.
The blower is attached to the thrashing machine by means of an iron
strap fixed to the blower by screws, and to the machine by screws and
nuts, and it is worked by two pulleys and a bolt, the driving pulley
being fixed on the drum spindle and the driven pulley on the spindle of
the blower. By these means I effect,―
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Day in the Great Seal Patent Office on the
7th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
DAY, Engineer to the Reading Iron Works, Limited, of Reading, in the
County of Berks, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of April, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Day, Her spécial license
that I, the said John Day, my executors, administrators, and assigns,
or such others as I, the said John Day, 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 THRASHING
.

page_text: MACHINES," upon the condition (amongst others) that I, the said John
Day, 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 imme
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Day, 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 relates to improvements in thrashing machines worked
by. animals or other motive power, being especially applicable to the type
of iron thrashing machines for which a Patent was granted to W: Exall;
dated 8th March 1848, No. 12,080, and manufactured by Barrett, Exall,
and Andrews, of Reading, whether such machines be worked by animal
or other motive power, whereby the corn is separated from the straw-and
cavings" without the use of a straw shaker, and whereby the corn is
also partially cleaned. These objects are attained by means of a blower
attached to and worked from the machine which separates the "cavings"
and an open platform formed of bars of wood or other material by which
the straw is conveyed away separately.
"
The blower is attached to the thrashing machine by means of an iron
strap fixed to the blower by screws, and to the machine by screws and
nuts, and it is worked by two pulleys and a belt, the driving pulley
being fixed on the drum spindle, and the driven pulley on the spindle of
the blower. By these means I effect,―.
1st. The separation of straw from the cavings..
2nd. The separation of corn from the straw.
3rd. The partial cleaning of the corn.
These improvements may be worked cither separately or in combina-
tion, so as to attain either or all of the objects above specified.
These improvements may be worked either separately or in combina-
tion, so as to attain either or all of the objects above specified.
· And in order that my Invention may be clearly understood and
readily carried into practice I will proceed to describe the Drawings
hereunto annexed.

page_text: DESCRIPTION OF THE DRAWINGS.
.
Figure 1 is a longitudinal elevation of a thrashing machine with
blower and straw rack combined therewith in accordance with my
improvements; Figure 2 is a sectional clevation; Figure 3 is a plan;
and Figure 4 is a plan in section. The letters on the Drawing refer to
corresponding parts in all the Figures.
a is an iron thrashing machine such as is ordinarily manufactured by
the Reading Iron Works, Limited; 6 is the ordinary feeding board used
for feeding the unthrashed corn into such machines; c is the blower
arranged and attached in accordance with my Invention to the thrashing :
machine a, and worked by means of pulleys and belting, as clearly shown
in the Drawing; d and e are the pulleys, and fis the belt for working
the blower; 9 is the rack for carrying away the straw separate from the
corn and cavings.
:
Having thus described the nature of my improvements in thrashing
machines, and the manner of performing or carrying the same into
practice, what I claim is, the improved construction of thrashing
machines arranged to act in combination with a blower c and straw
rack 9, substantially in the manner and for the purposes herein-before
described and represented in the Drawings hereunto annexed.
In witness whereof, I, the said John Day, have hereunto set my
hand and scal, this 3rd day of October, in the year of our Lord
One thousand eight hundred and seventy-four.
