portion of the shaft being provided with a number of hollow twisted
blade-like arms having slots formed therein.
The action of the apparatus is as follows:-The ground malt or
material to be operated upon having been admitted into the cylindrical
casing through the opening provided for that purpose, as already
mentioned, is carried along the same by the action of the helical blade
or screw formed upon the rotating hollow shaft until it comes in
contact with the hollow twisted blade-like arms before referred to, by
which latter it is thoroughly mashed in its passage along the casing
towards the mash tun, water or liquor of the requisite temperature
being simultaneously admitted to the material under treatment through
the perforations formed in the hollow lid shaft and slotted arms.
temperature of the water or liquor admitted may be regulated by means
of a thermometer, as frequently practised heretofore.

Patent..
NOW KNOW YE, that we, the said Alexander McGlashan and John.
Hendry, do hereby declare the nature of the 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 :-
This Invention has for its object improved machinery or apparatus
for mashing substances employed in the making of fermented liquors..
We make use of a cylindrical casing placed horizontally, such casing.
being provided at one end with an inlet for the material to be mashed,
and having at its opposite end an exit passage for the substances treated.
The upper part of this casing is made in the form of a hollow lid,.
which is-hinged to the remaining or under portion of the same, the outer
side of the lid being provided with an opening for the admission of water
or liquor, and its interior or concave side perforated with holes for the-
purpose herein-after mentioned. Within the cylindrical casing we place.
a perforated hollow shaft supported in bearings formed in the respective
ends of the casing, and which receives motion by hand or otherwise.

page_text: through suitable riggers or pullies attached to its outer end. Around
this shaft at the end nearest to the inlet for the substances to be mashed
is arranged a helical blade or screw, the remaining part or portion of
the shaft being provided with a number of hollow twisted blade-like
arms having slots formed therein.
The apparatus is shewn in the accompanying Drawings, whereof
Fig. 1 represents a longitudinal vertical section, and Fig. 2 a cross
section through the line A, B, of Fig. 1.
a is the cylindrical casing, made by preference of tinned copper, and
placed horizontally; 6 is the inlet opening for the material to be mashed,
which may be fed through a hopper in the usual manner; c is the exit
passage by which substances leave the apparatus after having been
treated therein; d is the upper part of the casing, made in the form
of a hollow lid, which is hinged as shewn at x to the remaining or
under portion of the casing a, and kept closed by pins x¹; e is the
opening provided in the outer side of the lid for the admission of water
or liquor; d is the interior or concave side of the lid, and f are the
holes with which it is perforated; g is the perforated hollow shaft,
into which water or liquor enters at g'; or the shaft may be arranged
for water or liquor to enter at its other end; h, h', are the bearings
in which the shaft is supported; i is a pulley fixed on to the hollow
shaft g, and which receives motion from a strap, as well understood;
is a loose pulley capable of rotating upon the shaft g, the strap being
slipped on to this pulley when it is desired to discontinue the rotation
of the shaft; kis the helical blade or screw arranged around the shaft
at the end nearest to the inlet opening b. It is made hollow, so that
its interior communicates, as shewn, with the interior of the shaft g,
and it is formed or provided with holes or apertures 7 for the passage
of water or liquor from its interior to mix with the substances under
treatment, as herein-after mentioned; m are the hollow blade-like arms
screwed into the shaft g, and twisted or set at an angle, as shewn, and
having slots n formed therein; o is the bracket by which the apparatus is
secured to the mash tun p; and q is a suspended bracket for supporting
the other end of the apparatus.
The action of the apparatus is as follows:-The ground malt or
material to be operated upon having been admitted into the cylindrical
casing through the opening provided for that purpose, as already
mentioned, is carried along the same by the action of the helical blade

page_text: or screw formed upon the rotating hollow shaft until it comes in contact
with the hollow blade-like arms before referred to, by which latter it
is thoroughly mashed in its passage along the casing towards the mash
tun, water or liquor of the requisite temperature being simultaneously
admitted to the material under treatment through the perforations formed
in the hollow lid, shaft, screw, and slotted arms. The temperature of the
water or liquor admitted may be regulated by means of a thermometer,
as frequently practised heretofore.
By the combination and arrangement on a horizontal shaft of the
screw blade for impelling the malt with a series of hollow perforated
blade-like arms in a casing provided with a hollow perforated lid for
mashing and simultaneously moistening and carrying forward the malt
as described, it is more thoroughly and more rapidly mashed than in
machines of the constructions hitherto proposed.
Having thus described the nature of our said Invention, and in
what manner the same is to be or may be carried into effect, we desire
to distinctly point out that we do not lay any claim whatever to any of
the mechanical parts separately, as it will be seen that the machine
described is in many respects similar to what has been previously used
or proposed for mashing; but we claim as our Invention the peculiar
combination of machinery or apparatus arranged and operating as
described for the purpose specified.
In witness whereof, we, the said Alexander McGlashan and John
Hendry, have hereunto set our hands and seals, this Twenty-
second day of September, in the year of our Lord One thousand
eight hundred and sixty-eight.
