AN IMPROVEMENT IN BEATERS FOR THRASHING MACHINES
Year: 1860

page_text: LETTERS PATENT to John Goucher, of Worksop, in the County of Not-
tingham, Ironfounder, Engineer, and Machinist, for the Invention of
"AN IMPROVEMENT IN BEATERS FOR THRASHING MACHINES."
Sealed the 25th January 1861, and dated the 31st July 1860.
PROVISIONAL SPECIFICATION left by the said John Goucher, at the
Office of the Commissioners of Patents, with his Petition, on the 31st-
July 1860.
I, JOHN GOUCHER, of Worksop, in the County of Nottingham, Ironfounder,
Engineer, and Machinist, do hereby declare the nature of the said Invention for
"AN IMPROVEMENT IN BEATERS FOR THRASHING MACHINES," to be as follows:-
This Invention relates to beaters of the description for which I obtained
Letters Patent, dated 25th November 1848, No. 12,348, which beaters are
formed with grooves or channels in their working surfaces, and my present
improvement consists in giving to these grooves or channels a form unlike that.
described in the Specification of the aforesaid Patent, in which the opposite
sides of each individual groove or channel were shown formed alike; I now.
form the groove or channel with the working side vertical or nearly so, and
the other side inclined and rounded or of a convex curved form in such manner.
that the working side or edge of each of the beating projections shall be square
and the other side or edge shall be rounded off whereby the passage of the
grain is more effectually secured, and the action of the beater is materially
improved.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GOUCHER, of Worksop, in the County of Nottingham, Ironfounder, Engineer,
and Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of July in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth 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 "AN IMPROVEMENT IN
BEATERS FOR THRASHING 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,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 imme-
diately 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 by the following.
statement thereof, reference being had to the Drawings hereunto annexed,
that is to say:
•
This Invention relates to beaters of the description for which I obtained
Letters Patent, dated the Twenty-fifth November, One. thousand eight hundred
and forty-eight, No. 12,343, which beaters are formed with grooves or channels.
in their working surfaces, and my present improvement consists in giving to
these grooves or channels a form unlike 'that described in the Specification of
the aforesaid Patent in which the opposite sides of each individual groove or
channel were shown formed alike; I now form the groove or channel with
the working side vertical or nearly so, and the other side inclined and.rounded
or of a convex curved form in such manner that the working side or edge of

page_text: each of the beating. projections shall be square, and the other side or edge
shall be rounded off, whereby the passage of the grain is more effectually
secured and the action of the beaters is materially improved.
Figure 1 of the accompanying Drawings is a plan; Figure 2, a side elevation
and Figure 3, a longitudinal section through the line x, y, of Figure 1 of a
beater constructed according to my Invention.
a is the vertical side of the working part of the beater or bar; it is made at
right angles or nearly so, as shown, to the bar b, the other side of the beater,
videlicit, that marked c is made at an angle with the bar, as shown.
Figure 4 shows in plan, Figure 5 in side elevation, and Figure 6 in longi-
tudinal section, through the line v;, w, of Figure 4, a beater with the rib made
of a somewhat different form, but still maintaining the side marked a at a
right angle, or nearly so, with the bar b.
Figure 7 shews in longitudinal section, part of a beater or bar in which the
working side a is slightly inclined in the direction from e to f; the other side c is
shown made of a different form to that of the bars or beaters before shown. In any
case the ribs may extend across the bar or only partially across, or they may be
otherwise arranged as found most convenient for the work to be performed.
The bars or beaters may be made of malleable or wrought iron or of any other
suitable material.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I do not limit myself to
any particular shape or form for that side of the beater marked in the Drawings
c, or to the distance at which the ribs are placed from one another, or to the
depth thereof, for the same may be varied without departing from my Invention;
but what I claim as my improvement in beaters for thrashing machines is
forming the working side of the groove or channel vertical with or at right
angles or nearly so to the beaters or bars as herein-before described and illus-
trated in the accompanying Drawings.
In witness whereof, I, the said John Goucher, have hereunto set my
hand and seal, this Thirty-first day of January, in the year of our Lord
One thousand eight hundred and sixty-one.
JOHN GOUCHER. (L.S.)
