Improvements in Malt Mashing and Extracting Machines.
THOMAS CLEMINSON Engineer 20 Breakfield Road South Liverpool, England,
do hereby declare the nature of this invention to be as follows:-
This invention is illustrated by the accompanying drawings which shew a malt
mashing or extracting machine provided with my improvements in combination,
Figure being a longitudinal sectional elevation, Figure 2 a plan, and Figure 3
transverse sectional elevation.
In the machine shewn, a is a chamber having a jacket a' into which the mashing
liquid is introduced. This jacket has a perforated inner case a through which
the water is injected, the grain to be treated being introduced through said
chamber, and the water sprayed onto same as it passes through. Within this
chamber there is used a second perforated chamber b, that shewn being conical;
from which water is sprayed at the central part from within, and onto which the
malt falls, and is directed in an annular stream in passing through the said
chamber, the water being discharged from said chamber b through holes therein,.
and sprayed outwards towards the inner casing a². c is a vessel below 6 having a
valve c¹, and a rose e², the supply of liquor from which is governed by said:
valve. The supply of liquid to the chambers b and c is effected by conduits d
from the jacket a'; and the valve c¹ is operated from outside by the rod c³ (see
Figure 3).
e is a base carried by the inlet or mouth of the upper part of the horizontal
cylindrical part below, upon which the chamber a is supported, such chamber being
adapted to slide onto and off said base, whereby it can be readily taken off,
inspected, cleaned, etcetera.
The lower cylindrical part is designated f, and has an external jacket f'in which
water is introduced, and in some cases the internal casing f2 thereof is provided with
apertures at the top side through which water is sprayed onto material being
treated therein. g is a revolving shaft in the cylinder having blades, and arms.
thereon, as shewn. These blades and arms consist of a blade portion h, and a
rod on the end of same, which passes through the shaft g, and is held therein
by a nut g, the function of the blades and rods being to stir, mix, and feed' forward
the grain along the vessel.
The action of the apparatus shewn is, that water is injected from the jacket a¹
of the vessel a towards the axis thereof (and slightly upwards due to, the form of
the inner lining a²), and water is also sprayed outwards from the chamber b,
whilst the malt to be operated upon is charged into the upper endi of the vessell a,
and formed into an annular or distributed stream by the inner vessel b; and as it
falls through a, it is sprayed or showered upon from both sides. From the vessel a,
it falls into the vessel f, at the entrance of which, when required, it is further
subjected to a shower of water discharged from the rose c². As it falls into the
vesself, the shaft of which is being rotated, it is mixed-and carried along-it
towards the opposite end, being discharged from the spout i; and, when desired,
further water is showered upon it from the apertures in the inner casing f
By the combined action or operation upon the malt in the vessel a,, and
subsequently in the vessel f, it cannot fail throughout to be thoroughly and
homogeneously moistened or steeped by the time it arrives at the outlet is in every
part; that portion, if any, which fails to be properly wetted in passing through a,

page_text: receiving the desired wetting in the vessel fin being stirred, mixed, broken up and
fed forward therein, thus securing the thorough mashing of, or extraction from,
every particle of the malt.
Besides affording a means of supplying water to the apertures in the inner casing f²,
the jacket f' serves to keep the vesself warm.

Improvements in Malt Mashing and Extracting Machines.
I, THOMAS CLEMINSON, of 20 Breckfield Road South, Liverpool, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention has reference to malt mashing or extracting machines, and its
construction and node of use and action, and the combination of parts of which it
is composed, are fully described with reference to the drawings (left with my
Provisional Specification), the novel features and improvements which it is desired
to claim and cover by Letters Patent being specified or pointed out in the
claiming clauses concluding the Specification.
The drawings shew a malt mashing or extracting machine provided with my
improvements in combination, Figure 1 being a longitudinal sectional elevation,
Figure 2 a plan, and Figure 3 a transverse sectional elevation.
In the machine shewn, a is a chamber having a jacket a', into which the mashing
liquid is introduced. The jacket has a perforated inner case a through which
the water is injected, the grain to be treated being introduced through said
chamber, and the water sprayed onto same as it passes through. Within this
chamber there is used a second perforated chamber b, that shewn being conical,
from which water is sprayed at the central part from within, and onto which the
malt falls, and is directed in an annular stream in passing through the said
chamber, the water being discharged from said chamber through holes therein,
and sprayed outwards towards the inner casing a². c is a vessel below 6 having a
valve c', and a rose c², the supply of water from which is governed by said
valve. The supply of water to the chambers b and c is effected by conduits d
from the jackets a¹; and the valve c' is operated from outside by the rod c³ (see
Figure 3).
e is a base carried by the inlet or mouth of the upper part of the horizontal
cylindrical part below, upon which the chamber a is supported, such chamber
being adapted to slide onto and off said base, whereby it can be readily taken off,
inspected, cleaned, etcetera.
The lower cylindrical part is designated f, and has an external jacket f'in which
water is introduced; and in some cases the internal casing thereof is provided with
apertures at the top side, through which water is sprayed onto material being
treated therein. 9 is a revolving shaft in the cylinder having blades and arms
thereon, as shewn. These blades and arms consist of a blade portion h, and a
rod h¹ on the end of same, which passes through the shaft g, and is held therein
by a nut g', the function of the blades and rods being to stir, mix, and feed forward,
the grain along the vessel.
The action of the apparatus shewn is, that water is injected from the jacket a¹
of the vessel a towards the axis thereof (and slightly upwards due to the form of
the inner lining a²), and water is also sprayed outwards from the chamber b, whilst
the malt to be operated upon is charged into the upper end of the vessel a, and

page_text: a,
formed into an annular or distributed stream by the inner vessel b; and as it falls
through a, it is sprayed or showered upon from both sides. From the vessel it
falls into the vessel f, at the entrance of which, when required, it is further
subjected to a shower of water discharged from the rose c. As it falls into the
vessel f, the shaft g of which is being rotated, it is mixed and carried along it
towards the opposite end, being discharged from the spout i; and, when desired,
further water is showered upon it from the apertures in the inner casing f2.
a,
By the combined action or operation upon the malt in the vessel and
subsequently in the vessel f, it cannot fail, throughout, to be thoroughly and
homogeneously moistened or steeped by the time it arrives at the outlet i, in every
part; that portion, if any, which fails to be properly wetted in passing through a,
receiving the desired wetting in the vessel fin being stirred, mixed, broken up and
fed forward therein, thus securing the thorough mashing of, or extraction from,
every particle of the malt.
Besides affording a means of supplying water to the apertures in the inner casing ƒ³,
the jacket f' serves to keep the vessel f warm.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvement herein described in malt mashing and extracting machines;
namely, a machine comprising a chamber through which the grain is passed, and
wherein the mashing water is sprayed onto the grain; and a chamber below into
which the grain and water pass from the above specified chamber, and wherein they
are stirred and mixed by suitable stirring devices; operating substantially as and
for the purposes specified.
2. In a malt mashing and extracting machine comprising an upper and lower
chamber as specified, adapting and arranging the upper vessel on the lower by a
sliding joint; substantially as set forth for the purposes specified.
3. The upper and lower chambers having their parts combined, constructed, and
adapted to operate particularly as set forth with reference to and as shewn in the
drawings.
