I, HERBERT JOHN HADDAN, of the firm of Herbert and Company Patent Agents,.
of 67, Strand, in the City of Westminster, Civil Engineer, do hereby declare the
nature of said Invention for "IMPROVEMENTS IN OR CONNECTED WITH BREWING
APPARATUS," a communication to me from abroad by Benjamin Gervais, of
Montmorillon, France, to be as follows:-
This invention relates to brewing apparatus or plant.
It comprises a grinding apparatus provided with a hopper for receiving the malt
and consisting chiefly of two grooved cylinders operated by means of a driving
shaft set in motion either by means of a crank or an endless belt.
This grinding apparatus is connected below with a vertical pipe provided at the
lower end with a spout serving to discharge the ground malt into the mash-tun
situated below. This discharge pipe is composed of two parts the lower part (with
the spout) being connected with the upper part in such manner that it may turn
round its vertical axis; a suitable appliance serving to fix the lower part with the
spout in any desired position.
Near the lower end and above the spout, the discharge pipe is provided with a
valve serving to arrest the passage of the malt when the spout is displaced for the
purpose of removing the cover of the mash-tun.
Above the mash-tun is situated a cold water reservoir made of cast-iron and fed
in any suitable manner.
This reservoir is provided with a cock serving to discharge the water into a
boiler made of enamelled cast-iron having a cover of the same material and which
is connected with a counter weight.
This boiler is suspended in the centre of a furnace and held in position by means
of hinges so as to permit the heat generated in the furnace to circulate round the
boiler.
The mash-tun comprises a cylindrical outer vessel made of tin plato and
containing a second vessel of the same material the bottom of which is perforated
and situated about four centimetres above the bottom of the first vessel.
Through the centre of the cover of the second vessel passes a vertical rod, having
a radial arm made of hoop iron Under this arm is mounted another arm slightly
longer than the first and carrying 8 small metallic branches placed vertically and
De

page_text: to the lower end of which is rivetted a tinned iron band extending to the bottom
of the vessel. This band acts as a "rack" or "oar" for stirring the malt which
arrives in this vessel from the grinding apparatus situated above.
The stirring appliance is set in motion by a vertical shaft and a crank.
This shaft is held in bushes and carries above a pinion gearing into a toothed
wheel forming one piece with the rod of the stirring appliance.
This rod is connected at the upper end, below the toothed wheel, with a bracket
fixed to the cover of the vessel and serves at the same time as a support for the
rotary shaft operating the stirring appliance and which is held at its lower end
in a socket passing through the bottom of the exterior vessel and rivetted to
the same.
This socket is provided with a screw acting in vertical direction and serving to
control the motion of the rack.
The mash-tun with the stirring appliance is suitably arranged to permit the
cleaning of the same.
The mash-tun works as follows:
The malt coming from above is introduced into the inner vessel of the mash-tun
through a hopper, while the hot water is introduced from the boiler into the outer
vessel of the mash tun thro gh a pipe controlled by a cock. The pressure forces
the water from the outer essel into the inner vessel through the perforated
bottom of the same, after which the rack is set in motion, and after the wort
has been sufficiently agit ed it is conducted into the wort reservoir. This
reservoir consists of a cindrical vessel of tin plate the bottom of which is
slightly inclined towards the wort boiler so as to assist the discharge of the pulpy
mass of wort into the wort boiler. The cover of the wort-reservoir is also
connected with a counterweight. The wort boiler is of the same construction
as the hot water heater above described and provided with suitable means for
discharging the wort into the cooling trough after it has been boiled.
The cooling trough is provided with a movable bottom and cocks for discharging
the liquid into the fermenting vessels situated under the cooling trough.
The fermenting vessels are made of enamelled cast iron and adapted to be closed
hermetically. In the centre of the cover which is made of the same material, there
is an aperture for the escape of the gases produced by the fermentation. From
the fermenting vessels the liquid passes into the clarification vessels of similar
construction and material as the fermenting vessels and situated under the same.
The chamber containing the fermenting and clarification vessels is connected
with a ventilation shaft leading outside the building.

page_text: I, HERBERT JOHN HADDAN, of the firm of Herbert and Company, Patent
Agents, 67, Strand, Westminster, Civil Engineer, for "IMPROVEMENTS IN OR
CONNECTED WITH BREWING APPARATUS," a communication to me from abroad by
Benjamin Gervais, Montmorillon, France, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to brewing apparatus or plant.
It comprises a grinding mill A surmounted by a hopper a for receiving the malt;
the grinding apparatus b is formed of two grooved cylinders set in motion by
means of a fly-wheel a³ provided with a handle or adapted to receive an endless
belt.
The discharge pipe is divided at c, the lower part being made movable around
its vertical axis, so that it can be turned in all directions with the spout & forming
the lower end and serving to discharge the malt into the mash-tun.
The position of the lower or movable part of the discharge pipe with the spout is
controlled by a key c, and a valve placed inside the discharge pipe, above the spout,
permits to arrest the discharge of the crushed malt.
B is a boiler made of enamelled cast iron and provided with a cover made of the
same material and adapted to be lifted by means of the counterweight b¹.
This boiler is suspended by means of hinges in the centro of a furnace D, so that
the heat generated in the fire place d' will circulate round the boiler B. c¹ is the
cock serving to feed the mash-tun with the necessary quantity of hot water.
The mash tun comprises a cylindrical vessel F made of tin plate and containing
a vessel E having a perforated bottom situated 4 centimetres above the bottom of
the vessel F.
Through the centre of the cover of the vessel E passes a vertical shaft g carrying
a radial arm h made of tinned flat iron.
Under this first arm is mounted another arm h¹ slightly longer than h and
carrying 8 metallic branches i placed vertically.
To the lower ends of these branches i is rivetted a band ¹ which extends to the
bottom of the vessel E and acts as a rake or agitator so as to stir the malt
(introduced into the mash tun), when the stirring appliance is set in motion by
the shaft j operated by the fly-wheel K, which is provided with a handle.
At the other end the shaft j terminates with a pinion m which gears into a tooth
wheel mounted on the shaft g.
This shaft g passes at its upper end, below the tooth-wheel, through a guide or
bracket fixed to the cover and serving at the same time as a support for the shaft j;
the lower end of g turns in a step bearing rivetted to the bottom of the vessel F;
this step-bearing or socket piece is made vertically adjustable by a screw which
serves to control the play of the stirrer it. The counter weight P serves to remove
the whole system for the purpose of cleaning.
ris the hopper for introducing the malt into the vessel E.
From the vessel F the mass passes through cock f¹ into the boiler I, the
construction of which is the same as that of the boiler B.
After boiling, the mass is discharged through the cock into the cooling
vessel R.
In the vessel I and in front of the cock there is a filter. The trough R is
covered with a movable platform and provided with cocks t, through which the
liquid passes into the fermenting vessels o. The vessels o are made of enamelled

page_text: cast iron and closed by a hollow cover l, the bottom of which is slightly conical
the top of this cone is perforated with the aperture n; so that in proportion to
the fermentation the leaven leaves the vessel and accumulates in the hollow cover l
from which it can easily be removed; the cover floating on the liquid, descends
by its own weight in proportion as the liquid diminishes owing to fermentation.
V are clarifying vessels of the same construction as the vessols o.
These vessels are placed on a metallic platform and adapted to slide on the same
according to requirements.
The cooling trough, as well as the vessels o and V, are placed underground, while
the other parts of the apparatus may be arranged in the open and covered by a roof
of sheet iron.
The browing plant described simplifies the manipulation and requires no special
skill for the same; it is therefore specially suitable for operations on a small
scale, although the same system may also be adapted for brewing large quantities
of beer.
6 Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declaro that what
