I, JOHN THOMPSON, of Abbot Street, Wrexham, in the County of
Denbigh, Brewer, do hereby declare the nature of the said Invention
for "AN IMPROVED METHOD OF MASHING MALT OR GRAIN," to be as follows:-
This Invention consists of a cylinder with a perforated casing con-
nected underneath the malt or grain hopper with perforated horizontal
and perpendicular tubes, the said tubes being so constructed that the
malt or grain cannot escape without being thoroughly wet before
meeting with the paddles underneath, the paddles being so constructed

page_text: and fixed in a chamber below connected to the cylinder above that the
malt or grain is thoroughly mashed before it leaves the paddles.
The paddles are fixed upon two horizontal spindles, the arms of each
paddle working up to the opposite spindle with a beater which carries
the malt or grain and water forward to the conductor below, and thence a
to mash tub.
The paddles are regulated by two wheels, which are kept in rapid
motion by the malt or grain and water passing between the paddles.
In place of the horizontal and perpendicular perforated tubes there
may be used a perforated cone or worm, and this cone or worm may be 1
used as a fixture or revolving. Perforated pipes may also be used in the
paddle chamber or conductor.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Thompson in the Great Seal Patent Office
on the 14th June 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN

|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 immediately after the date of the said Letters
Patent
NOW KNOW YE, that I, the said John Thompson, 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: -
A cylinder with a perforated casing connected underneath the malt or
grain hopper with perforated horizontal and perpendicular tubes, the
said tubes being so constructed that the malt or grain cannot escape
without being thoroughly wet by water passing through the perforations
in the cylinder and tubes before meeting with the paddles underneath,
the paddles being so constructed and fixed in a chamber below connected
to the cylinder above that the malt or grain is thoroughly mashed before
it leaves the paddles.
The paddles are fixed upon two horizontal spindles, the arms of each
paddle working up to the opposite spindle, with a beater at the end of
each arm of the paddle, which carries the malt or grain and water forward
to the conductor below, and thence to mash tun.
The paddles are regulated by two wheels, which are kept in rapid
motion by the malt or grain and water passing between the paddles.
In place of the horizontal and perpendicular perforated tubes there
may be used a perforated cone or worm, and this cone or worm may be
used as a fixture or revolving. Perforated pipes may also be used in the
paddle chamber or conductor.
And in order that my said Invention may be properly understood and
readily carried into effect I will proceed to describe the same with
reference to the annexed Drawings, wherein Figure 1 represents the
side elevation, showing two regulating wheels; Figure 2 represents
section showing chamber and perforations, through which perforations
water comes to thoroughly wet the grain or malt, and also showing the
mode of the malt or grain passing on to the paddles or beaters below;
Figure 3 represents the end elevation; Figure 4, the paddles with beaters

page_text: at the end of each arm, such beaters being constructed of sheet metal.
These are the paddles referred to in the description of Figure 2.
In witness whereof, I, the said John Thompson, have hereunto
set my hand and seal, this Twelfth day of June, in the year of
our Lord One thousand eight hundred and seventy-six.
Witness,
W* PARRY,
