PROVISIONAL SPECIFICATION.
Improvements in Rousing Beer and Mixing or Blending Wort or
Gyle, and in Apparatus employed therein.
I, JOSEPH FREDERICK LITTLETON of 22 Eden Street, Kingston-on-Thames in the
County of Surrey, Brewer, do hereby declare the nature of this invention to be as
follows:
My invention has reference primarily to the process of rousing beer and it con-
sists in lifting the beer by means of a vessel having an up and down movement,, or
otherwise, from the bottom of the vat or tun and then discharging the liquor in
numerous fine streams or showers upon the surface of the main body of the liquor
whereby the "head" is washed in and the beer is well aërated. This process has the
advantage of retaining in the beer the finest flavor of the hop which is always
thrown up the first day after brewing. The invention comprises the apparatus
hereinafter described for effecting the process.
For the purpose of carrying out the process 1 employ a vessel of any suitable shape
and capable of containing a quantity of liquid from a few gallons upwards.
This vessel, which should be suitably weighted, is fitted with a lifting valve at
bottom and is formed all round the sides with numerous holes and provided with any
suitable or convenient arrangement whereby it can be alternately lowered to the
bottom of the vat or tun and lifted from the same to a level above the surface of the
liquor. Consequently as the vessel is being lowered into the liquid it sinks readily
owing to the lifting valve at bottom and becomes filled with the liquor. When it has
again been raised above the surface of the liquor this flows out through the numerous
holes in the form of a shower or fine streams upon all sides and therefore not only
aërates the liquor but washes in the head, and it materially assists the fermentation
by the introduction of the young yeast which is thrown to the surface.
Instead of employing a vessel which has the alternate downward and upward
movements as above described I can employ a vessel fitted. above the surface
of the liquor in the vat or tun and formed all round with numerous holes as
already described, and in connection with this vessel I can use a pump to raise the
liquor from the bottom of the vat and deliver it into this vessel; or the delivery pipe
or portion of the pump may itself consist of a chamber or vessel formed with numerous
holes through which the liquor pumped up will pass in a fine shower so as to fall
upon the top of the liquor in the vat."
My invention is also applicable to the mixing or blending of wort or gyle the
apparatus being applied to any fermenting vessel, the result being that the wort is
perfectly aërated and becomes of good flavor and of brilliant condition.

COMPLETE SPECIFICATION.
Improvements in Rousing Beer and Mixing or Blending Wort or
Gyle, and in Apparatus employed therein.
I, JOSEPH FREDERICK LITTLETON of 22 Eden Street, Kingston-on-Thames in the
County of Surrey Brewer, 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: --
-
My invention has reference primarily to the process of rousing beer, and it con-
sists in lifting the beer by means of a vessel having an up and down-movement,
or otherwise, from the bottom of the vat or tun and then discharging the liquor in
D077

page_text: numerous fine streams or showers upon the surface of the main body of the liquor,
whereby the "head" is washed in and the beer is well aerated. This process has
the advantage of retaining in the beer the finest flavor of the hop which is always
thrown up the first day after brewing. The invention comprises the apparatus herein-
after described for effecting the process.
For the purpose of carrying out the process I employ a vessel of any suitable shape.
and capable of containing a quantity of liquid from a few gallons upwards. This
vessel, which should be suitably weighted is fitted with a lifting valve at bottom and
is formed all round the sides with numerous holes and provided with any suitable or
convenient arrangement whereby it can be alternately lowered to the bottom of the
vat or tun and lifted from the same to a level above the surface of the liquor. Conse-
quently as the vessel is being lowered into the liquor it sinks readily owing to the
lifting valve at bottom and becomes filled with the liquor. When it has again been
raised above the surface of the liquor its contents flow out through the numerous
holes in the form of a shower or fine streams upon all sides and therefore not only
aërates the liquor but washes in the head, and it materially assists the fermentation by
the introduction of the young yeast which is thrown to the surface.
Figure 1 of the annexed drawings represents an apparatus constructed as above
described a represents the vat or tun in section. b is the vessel which is alternately
lowered to the bottom of the vat a and lifted from the same to a level above the
surface of the liquor therein; any suitable or convenient arrangement for lowering
and raising the vessel can be adopted. e is a lifting valve at the bottom of the vessel b
and d d are holes formed all around the vessel. It will readily be understood that
as the vessel b is being lowered into the liquid in the vat a it sinks readily owing to
the lifting or opening of the valve at bottom and becomes filled with the liquor, and
that when it has again been raised above the surface of the liquor its contents flow
out through the numerous holes d d in the form of a fine shower or streams upon all
sides, producing the effect already hereinbefore explained.
Instead of employing a vessel which has the alternate downward and upward
movement as above described 1 can employ a vessel fitted above the surface of the
liquor in the vat or tun and formed all round with numerous holes as already described,
and in connection with this vessel I can use a pump to raise the liquor from the
bottom of the vat and deliver it into this vessel; or the delivery pipe or portion of the
pump may itself be formed with numerous holes through which the liquor pumped up
will pass in a fine shower so as to fall upon the top of the liquor in the vat; or the
delivery pipe may be fitted with a nozzle so as to discharge the liquor in the form of
a jet.
This modification is represented in Figure 2 in which e represents the pump hooked
or attached to the vat or tun a its suction pipe f being connected to a cock g com-
municating with the lower part of the vat. The delivery pipe h which may con-
veniently be formed of an india rubber tube is fitted at the end either with a nozzle i
so as to discharge the liquor in the form of a jet or with a rose j or spray producer k
(see the detached views) so as to discharge the liquor in a shower or state of fine
division. Instead of the jet, rose or spray producer on the end of the delivery pipe h
this pipe may extend across the vat and be formed all over its lower part with fine
holes; or the delivery pipe may consist of or comprise a chamber or vessel formed
with numerous holes, or it may deliver into a separate vessel above the vat a, this
vessel being formed with numerous holes.
My invention is also applicable to the mixing or blending of wort or gyle, the
apparatus being applied to any fermenting vessel, the result being that the wort is
perfectly aërated and becomes of good flavor and of brilliant condition. The apparatus
shown in Figure 2 is preferred for this purpose.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1 In the rousing of beer, the lifting of the liquor from the bottom of the vat, tun

page_text: or vessel in which it is contained to a point above the level of the main body of liquor
and then discharging the liquor thus litted in streams or showers upon the surface of
the main body substantially as and for the purpose hereinbefore described.
2. In the mixing or blending of wort or gyle, the lifting of the wort or gyle from
the bottom of the tun or vessel in which it is contained to a point above the level of the
main body of liquor, and then discharging the liquor thus lifted in streams or showers
upon the surface of the main body, substantially as and for the purpose hereinbefore
described.
3. The apparatus hereinbefore described with reference to the annexed drawings to
be employed in the rousing of beer or in the mixing or blending of wort or gyle in
the manuer set forth.
