page_text: LETTERS PATENT to Henry Bradley, of Hull, in the County of York,
Merchant, and Elmit Wray, of the same Place, Machino Maker, for tho
Invention of "IMPROVEMENTS IN BEATERS USED IN THRASHING MACHINES."
Sealed the 3rd September 1857, and dated the 14th March 1857.
PROVISIONAL SPECIFICATION left by the said Henry Bradley and Elmit
Wray at the Office of the Commissioners of Patents, with their Petition,
on the 14th March 1857.
We, HENRY BRADLEY, of Hull, in the County of York, Merchant, and
ELMIT WRAY, of the same Place, Machine Maker, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN BEATERS USED IN THRASHING
MACHINES," to be as follows:-
We take any number of strips of iron or other metal with channels crossing
diagonally on their face, so as to form an irregular diamond-shaped surface,
and we fix these on the ordinary wooden beaters, or arrange the iron strips so
as to form the beater complete, and fix them directly on drum centres without
wood. Or we take wire and wrap it round (or fix it on) the ordinary wooden
beater, so as to form a similar irregular diamond-shaped surface, as above.

Office on the 14th September 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
BRADLEY, of Hull, in the County of York, Merchant, and ELMIT WRAY, of the
same Place, Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of March, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Henry Bradley and Elmit Wray, Her special licence that we, the said
Henry Bradley and Elmit Wray, our executors, administrators, and assigns,
or such others as we, the said Henry Bradley and Elmit Wray, our 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 USED IN THRASHING
MACHINES," upon the condition (amongst others) that we, the said Henry
Bradley and Elmit Wray, or one of us, our executors or administrators, by
an instrument in writing under our, or their, or one of our or their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, 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 Bradley and Elmit Wray, 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 thereof, reference being had to the Drawings
hereunto annexed, that is to say:-
We take any number of strips of iron or other metal with channels crossing
diagonally on their face, so as to form an irregular diamond-shaped surface,
and we fix these on the ordinary wooden beaters, or arrange the iron strips so
as to form the beater complete, and fix them directly on drum centres without
wood. Or we take wire and wrap it round (or fix it on) the ordinary wooden
beater, so as to form a similar irregular diamond-shaped surface, as above.
Figure 1 of the Drawings annexed is an end view of a drum fitted with our

page_text: beaters; Figure 2 is a plan thereof; Figure 3 is a view, in plan, of part of a
beater; and Figure 4 is a cross section of the beater plate.
A is a strip of iron or other suitable metal, which is made of a size to fix on
to the drum B, or to the ordinary wooden beaters. We form a series of
channels on the beater plate A, crossing each other at any desired angle, thus
leaving irregular diamond-shaped tapered projections C, D, E, between the
points of intersection. These rows of projections can be of various sizes, as
shewn in the Drawing, or they may be all formed of the same size. The pro-
jections C, D, E, may be forged or cast on to the beater plate, or may be fixed
in any other suitable manner. F, F, are holes, through which screws are
passed to secure the plate to the drum.
.And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim the forming of
beaters used in thrashing machines with raised diamond-shaped projections on
the surface thereof, as herein-before described.
In witness whereof, we, the said Henry Bradley and Elmit Wray, have
hereunto set our hands and seals, this Twelfth day of September, One
thousand eight hundred and fifty-seven.

ELMIT WRAY.
