Nottingham, Engineer, for the Invention of "IMPROVEMENTS
BEATERS AND BEATER PLATES FOR THRESHING MACHINES."
IN
Scaled the 11th December 1874, and dated the 12th August 1874.
:
PROVISIONAL SPECIFICATION left by the said John Goucher at the
Office of the Commissioners of Patents, with his Petition, on the
12th August 1874.
i
I, JOHN GOUCHER, of Worksop, in the County of Nottingham, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
BEATERS AND BEATER PLATES FOR THRESHING MACHINES," to be as follows:-
In the Specifications of Letters Patent granted to me, dated 1848, and
numbered 12,348, and 1860, numbered 1856, I describe beaters or beater
plates for threshing machines, formed with grooves or channels in their
working surfaces, the working side of the groove or channel being.
vertical or nearly so, and the other side inclined and rounded, or of a
convex.curved form, or as shewn in the Drawing partly in a straight
line and partly curved at the top and bottom in such a manner that the

page_text: working side or edge of cach of the beating projections is squarc, and
the other side or edge rounded off.
The beaters or beater plates formed with surfaces in this manner are
not perfect, and my present improvements consist in an improved method
of forming the non-working sides of the beating projections, that is, tho
surfaces provided for the passage of the grain to secure a freer passage of
the grain and render the beaters and beater plates more perfect.
I adopt the vertical or working side of the raised surface, running
obliquely across the beaters or beater plates for pressing or rubbing out the
grain, as described in the Specification of the secondly above-mentioned
Patent, and I find that the grain can pass out more freely and a more
perfect beater or beater plate is obtained when the opposite side of the
raised surface or working projection is made in one concave curve or in
one inclined straight line throughout, and my present improvements
consist in making the opposite side of the raised surface or working
projection in one concave curve, or one inclined straight line through-
out, that is, from the top of the surface projection to the bottom, so that
by my present improvements I do away with the rounded parts at the
top and bottom of the side, and make the side terminate at a point at
each end.
By means of these improvements the surface projections of the
beaters or beater plates can be made at a less distance apart, whereby
the grain is more thoroughly rubbed and pressed out, and whatever may
be the kind or size of the grain to be threshed, it cannot get fixed or
jambed between the raised surfaces, and more space is afforded for its
passago after it has left the car than has been hitherto afforded in other
beaters or beater plates.

page_text: 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-four, in the thirty-
eighth 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, executors, adminis-
trators, 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 "INPROVEMENTS IN BEATERS
AND BEATER PLATES FOR THRESHING MACHINES," 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 așcer-
tain 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 I, the said John Goucher, do hereby declaro.
the nature of my 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, reference being had to the Drawings here-
unto annexed, that is to say:-
In the Specifications of Letters Patent granted to me, dated 1848, and
numbered 12,343, and my Provisional Specification by crror numbered
12,348, and in 1860, numbered 1856, I described beaters or beater plates
for threshing machines formed with grooves or channels in their working
surfaces, the working side of the groovo or channel being vertical, or
nearly so, and the other side inclined and rounded, or of a convex
curved form, or as shown in the Drawings partly in a straight line and
partly curved at the top and bottom, in such a manner that the working
side or edge of each of the beating projections is square or nearly so,
and the other side or edge rounded off.
4
The beaters or beater plates formed with surfaces in this manner are
not perfect, and my present Invention consists in an improved method

page_text: of forming the non-working side of the beating projections, that is, the
surfaces of the channels provided for the passage of the grain, to secure
a freer passage of the grain, and thus to render the action of the beaters
and beater plates more perfect.
I adopt the vertical or working side of the raised surface running a
obliquely across the beaters or beater plates for pressing or rubbing out
the grain as described in the Specification of the secondly above-
mentioned Patent, and I find that the grain can pass out more freely,
and a more perfect beater or beater plato is obtained, when the opposite
side of the raised surface or non-working projection is made in one
concave curve, or in one inclined straight line throughout, and my
present improvements consist in making the opposite sides of the raised
surface or non-working projection in one cavcave curve, or in ono
inclined straight line throughout, that is, from the top of the surface
projection to the bottom, so that by my present improvements I do
away with the rounded parts at the top and bottom of the side, and
make the side terminate at a point at each end or nearly so.
By means of theso improvements the surface projections of the
beaters or beater plates can be made at a less distanco apart, whereby
the grain is more thoroughly rubbed and pressed out, and whatever may
be the kind or size of the grain to be threshed it cannot get fixed or
jammed between the raised surfaces and more space is afforded for its
passage after it has left the ear than has been hitherto afforded in other

running to the right.
Figure 7 is a transverse section of the beater plate showing the pro-
jections rounded on the front side as it moves in the direction of the
arrow.
In all these Figures a represents the vertical or working side of the
projections, or that side which serves to press or rub out the grain;
and b, the non-working sido or that side along which the corn or grain
passes.:
Having now described the nature of my Invention, and in what
manner the same is to be performed, I hereby declare that I do not
claim the use of grooved beaters or beater plates generally; I claim the
construction of the back or non-working side of the raised projections of
beaters or beater plates for threshing corn, with surfaces concavely
curved, or in an inclined straight line, substantially in the manner and
for the purposes as herein described.
In witness whereof, I, the said John Goucher, have hereunto
set my hand and seal, this Eleventh day of February, in the
year of our Lord One thousand eight hundred and seventy-
five
Signed and sealed by the within-
named John Goucher in the
