In- PROVEMENTS IN BEATERS, BEATER BARS, OR PLATES FOR THRESHING CORN AND OTHER GRAIN
Year: 1873

page_text: LETTERS PATENT to John Goucher, of Worksop, in the County of
Nottingham, Engineer and Ironfounder, for the Invention of "In-
PROVEMENTS IN BEATERS, BEATER BARS, OR PLATES FOR THRESHING CORN
AND OTHER GRAIN."
Sealed the 80th January 1874, and dated the 12th August 1878.
PROVISIONAL SPECIFICATION left by the said John Goucher at the
Office of the Commissioners of Patents, with his Petition, on the
12th August 1878.
I, JOHN GOUCHER, of Worksop, in the County of Nottingham
Engineer and Ironfounder, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN BEATERS, BEATER BARS, OR PLATES FOR
THRESHING CORN AND OTHER GRAIN," to be as follows:-.
In the year 1848 I obtained Letters Patent, No. 12,843, for improve-
ments in threshing machines for threshing corn and other grain. The
improvements consisted in forming grooves or channels running
diagonally across the working surface of the beater of the revolving
drum or cylinder of the threshing machine as therein described.

page_text: In the year 1860 I obtained other Letters Patent, No. 1856, for
further improvements in the working surface of the beater or beater bar,
which consisted in forming the diagonal grooves or channels one side
vertical or nearly so, and the other side inclined or rounded.
To avoid repetition of descriptions I refer to the Specifications duly
filed in the proper office of these improvements.
My present improvements consist in making the raised ridges or walls
which form the grooves or channels in the working surface of the beater,
beater bar, or plate in part at right angles or nearly so, and in part
diagonally across the working surface of the beater, beater bar, or plate,
of similar dimensions as heretofore used by me described in the Specifi-
cations of my said former Patents.
•
I form my present grooves or channels with both sides of the raised
ridges or walls thereof vertical or nearly so, and I form the ends of the
walls of these grooves for a short distance, that is, where the grain enters
the groove, and where it passes out at right angles or nearly so with the
edge of the longitudinal bar or beater, or one side of the wall only may
be formed at right angles at one end of the groove, and the other side of
the wall at the other end of the groove, also at right angles, thus bringing
the walls of the grooves at each end to a point or wedge shape.
These beaters or beater bars can be placed upon the revolving
cylinder or drum in the usual manner, the grooves running diagonally,
one bar having the grooves inclining to the right and one to the left
alternately.
I prefer to form both sides of the wall of the groove vertical or nearly
so, and both ends at right angles alike, as thereby both sides of the wall
of the groove are capable with equal effect of beating or pressing out the
grain. Being thus formed when one side of the wall of the groove
becomes worn, the beater or beater bar or the entire revolving drum or
cylinder can be reversed, and the other side of the wall, of the groove
brought to operate. -

filed by the said John Goucher in the Great Seal Patent Office on

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GOUCHER, of Worksop, in the County of Nottingham, Engineer and
Ironfounder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of August, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Goucher, Her special licence
that I, the said John Goucher, my executors, administrators, and
assigns, or such others as I, the said John Goucher, 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
BEATERS, BEATER BARS, OR PLATES, FOR THRESHING CORN AND OTHER GRAIN,"
upon the condition (amongst others) that I, the said John Goucher,
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
5 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 John Goucher, do hereby declare
the nature of my said Invention,-and--in what manner the same is
to be performed, to be particularly described and ascertained in and
O by the following statement, reference being had to the caccompanying
Sheet of Drawings, and to the figures and letters marked thereon :-
In the year One thousand eight hundred and forty-eight, I obtained
Letters Patent, No. 12,848, for "Improvements in Threshing Machines
for Threshing Corn and other grain." The improvements consisted in
5 forming grooves or channels running diagonally across the working.
-

machine, as therein described.
In the year One thousand eight hundred and sixty, I obtained other
Letters Patent, No. 1856, for further improvements in the working
surface of the beater or beater bar, which consisted in forming the
diagonal grooves or channels one side vertical or nearly so, and the other
side inclined or rounded.
To avoid repetition of description, I refer to the Specifications of the
above-mentioned improvements duly filed in the proper office.
My present improvements consist in making the raised ridges or walls 1
which form the grooves or channels in the working surface of the
beater, beater bar, or plate, in part at right angles or nearly so, and in
part diagonally across the working surface of the beater, beater bar, or
plate, of similar dimensions as heretofore used by me, and described in
the Specifications above referred to.
1
I form my present grooves or channels with both sides of the raised
ridges or walls thereof vertical or nearly so, and I form the ends of the
walls of the grooves for a short distance running inwards from the edge
of the boater, that is, where the grain enters the groove, and where it
passes out at right angles to the edge of the longitudinal bar or beater, 2
or one side of the wall only may be formed at right angles at one end of
the groove, and the other side of the wall at the other end of the groove,
also at right angles, thus bringing the walls of the grooves at each end
to a point or wedge shape.
°

page_text: Figure 1 is a side view, and Figure 2 a plan of part of a beater or
beater bar or plate constructed according to my Invention, with that
part of the groove which is diagonal running to the right, and Figure 3
is a transverse section thereof cut through a ridge at the dotted line Z, Z,
in Figure 2. It will be seen that at each edge of the beater bar the
walls or ridges which form the grooves or channels A. are at right angles
to the length of the bar, but that in the middle of the bar they are
oblique or diagonal thereto. The ends of the walls or ridges are rounded
off, as shewn in Figure 8 at a, a, or they may be bevilled to facilitate the
entrance of the material operated on between the beater and the concave
part of the threshing machine within which the drum revolves.
Figure 4 is a plan of part of a beater of modified construction with
that part of the grooves which is diagonal, also running to the right. The
walls or ridges in this case being diagonal or oblique with their opposite
extremities bevilled off to a wedge shape so as to present on one side at
each end a surface at right angles to the length of the bar.
In all the 4 Figures & represents the raised walls or ridges; and A. the
grooves or channels.
Having thus described the nature of my said Invention, and in what
manner the same is to be performed, I wish it to be understood that I do
not claim beater bars or plates generally with grooves or channels for the
purposes of threshing, but what I claim is the construction of beaters,
beater bars, or plates with grooves or channels, substantially in the
manner and for the purposes herein-before described.
In witness whereof, I, the said John Goucher, have hereunto set
'my hand and seal, this Twelfth day of February, in the year
of our Lord One thousand eight hundred and seventy-four.
