IMPROVEMENTS IN THE MODE OF AND APPARATUS FOR, CLEANSING BEER
Year: 1884

page_text: I ANTHONY GAPPER SOUTHBY of St Aubin's Road, in the Island of Jersey,
Engineer do hereby declare the nature of my Invention for "IMPROVEMENTS IN
THE MODE OF AND APPARATUS FOR, CLEANSING BEER" to be as follows:-
My Improvements in the mode of, and apparatus for, cleansing Beer, are
applicable :-
First, to the process called Skimming, and consist in removing the yeast from
the top of the beer in the fermenting vat by means of a force pump, and forcing it
into filtre bags, or yeast presses, so that the frothy yeast removed from the top of
the beer in the fermenting vat is immediately separated into two parts, the more
or less solid yeast which remains in the filtre bags or yeast presses and the liquid
beer which drains away and which may be returned directly to the fermenting vat
or be otherwise utilised.
In carrying out my invention I employ several forms of apparatus; for instanco
I connect the suction pipe of the pump of any formn of apparatus for separating
yeast from beer in which the pressure is obtained by means of a force pump with
the pipe leading from a parachute.
Or, I lead such a suction pipe by flexible hose or otherwise into a vessel in the
fermenting vat adapted for collecting the yeast.
Or, I use a force pump either fixed or portable or on a wheel carriage and pump
out of such a vessel into filtre bags capable of sustaining some pressure the bags
being fixed to nozzles attached to the end of the delivery pipe which bags may
drain directly back into the fermenting vat or otherwise.
The filtre bags may be those ordinarily used for the purpose of filtering beer
from yeast consisting of a large bag of twilled calico inclosed in a smaller bag made
of string or in a smaller vessel of perforated metal as is well understood.
I sometimes use one of the forms of force pump called rotary, especially those
which act by means of two cog wheels gearing together and revolving in a tight
case and their numerous modifications.
If a parachute is not used, the vessel for collecting the yeast in the fermenting
vat may be of any convenient shape and be raised and lowered in any convenient
way, for instance a round or square vessel with sloping sides like a funnel
with the nozzle connected with the suction pipe or closed to form a well for
the suction pipe to draw from may be raised or lowered by a rack and pinion
D

page_text: or by a screw like a parachute or it may be weighted at the apex so that it
will sink in beer when empty and be raised or lowered by a cord passing
over a pulley and so that its position in the beer can be regulated and the yeast
swept into it as is well understood with parachutes or, in a round fermenting
vat a yeast collecting vessel with its bottom sloping down to form a well to be
connected with or for the suction pipe to draw from, may have its top shaped as a
radial segment of the surface of the beer, this vessel may be suspended by a rod
from each end from a beam acress the middle of the top of the vat held down by
cleats the two rods terminating in ratks worked by two pinions on one slinft
passing a plummer block along the beam for regulating the height of the vessel in
the beer and so that a radial skimmer may revolve on the centre one of the two
rods as an axis and sweep the yeast into the vessel the skimmer being passed round
in any convenient manner as for instance by a stick or cords.
Or, the top of the vessel may inside fit close to the side of a round fermenting
vat while the other side of the vessel forms a well to the arc formed by the other
side the bottom sloping down as before described.
Or, in a square ferimenting vat a similar shaped vessel may be used with its
straight side against the side of the vat and its curved side turned inwards.
Or, the top of the vessel may be triangular so as to fit the corner of the vat or
any shape that is most convenient for sweeping the yeast into it and to suit the
form of the vat.
Secondly My improvements are applicable to where the beer is cleansed in
casks or pontoons-In this case I make the yeast trough or shoot or stillion into
which the yeast falls from the cleansing casks with a bottom sloping sufficiently
for the yeast falling into it to run down to a well from which I pump it into filtre
bags or yeast presses and return the beer pressed out of the yeast to the cleansing
casks.

page_text: I ANTHONY GAPPER SOUTHBY of St Aubin's Road in the Island of Jersey,
Engineer do hereby declare the nature of my said Invention for IMPROVEMENTS
IN THE MODE OF AND APPARATUS FOR CLEANSING BEER, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My improvements in the mode of and apparatus for cleansing Beer are
applicable :-
:-
First to the process called Skimming and consist in removing the yeast from the
top of the beer in the fermenting vat by means of a force pump and forcing it
into filter bags or yeast presses, so that the frothy yeast removed from the top of
the beer in the fermenting vat is immediately separated into two parts, the more
or less solid yeast which remains in the filtre bags or yeast presses and the liquid
beer which drains away and which may be returned directly to the fermenting vat
or be otherwise utilized.
In carrying out my invention I employ several forms of apparatus; for instance,
I connect the suction pipe of the pump of any form of apparatus for separating
yeast from beer in which the pressure is obtained by means of a force pump with
the pipe leading from a parachute.
Or, I lead such a suction pipe by flexible hose or otherwise into a vessel in the
fermenting vat adapted for collecting the yeast.
Or, I use a force pump either fixed, portable, or on a wheel carriage, and pump
out of such a vessel into filter bags capable of sustaining some pressure the bags
being fixed to nozzles attached to the end of the delivery pipe which bags may
drain directly back into the fermenting vat or otherwise-The filter bags may be
those ordinarily used for the purpose of filtering beer from yeast consisting of a
large bag of twilled calico enclosed in a smaller bag made of string or in a smaller
vessel of perforated metal as is well understood.
I sometimes use one of the forms of force pump called rotary especially those
which act by means of two cog wheels gearing together and revolving in a tight
case and their numerous modifications.
If a parachute is not used the vessel for collecting the yeast in the fermenting
vat may be of any convenient shape and be raised and lowered in any convenient
way for instance, a round or square vessel with sloping sides like a funnel with
the nozzle connected with the suction pipe or closed to form a well for the suction
pipe to draw from may be raised or lowered by a rack and pinion or by a screw
like a parachute, or it may be weighted at the apex so that it will sink in beer
when empty and be raised or lowered by a cord passing over a pulley and so that
its position in the beer can be regulated and the yeast swept into it as is well
understood with parachute.
Or, in a round fermenting vat a yeast collecting vessel with its bottom sloping
down to form a well to be connected with or for the suction pipe to draw from
may have its top shaped as a radial segment of the surface of the beer as
shewn in drawing herewith-this vessel may be suspended by a rod from each
end from a beam across the middle of the top of the vat held down by cleats
the two rods terminating in racks worked by two pinions on one shaft passing
on plummer blocks along the beam for regulating the height of the vessel in
the beer, and so that a radial skimmer may revolve on the centre one of the
two rods as an axis and sweep the yeast into the vessel as shewn the skimmer
being passed round in any convenient manner, as for instance, by a stick or cords.

page_text: Or, the top of the vessel may inside fit close to the side of a round fermenting
vat while the other side of the vessel forms a cord to the arc formed by the other
side as shewn in Drawing herewith the bottom sloping down as before described.
Or, in a square fermenting vat a similar shaped vessel may be used with its
straight side against the side of the vat and its curved side turned inwards.
Or, the top of the vessel may be triangular so as to fit the corner of the vat or
any shape that is most convenient for sweeping the yeast into it and to suit the
form of the vat.
Secondly My improvements are applicable to where the beer is cleansed in
casks or pontoons.
In this case I make the yeast trough or shoot or stillion into which the yeast
falls from the cleansing casks with a bottom sloping sufficiently for the yeast falling
into it to run down to a well from which I pump it into filter bags or yeast presses
and return the beer pressed out of the yeast to the cleansing casks.
In the drawings hereto annexed the same letters represent corresponding parts
in all the Figures.
In Fig 1 A is the fermenting tun B the yeast collecting vessel, c the suction
pipe of the pump D of which E is the rising or exit main conducting the yeast
from the pump D to the bags G G attached to the nozzles F F.
Fig. 2 is a birdseye view of the same arrangement only that the exit main E is
shewn passing outside the fermenting vessel so as to conduct the yeast to bags not
shown which allow the beer as it filters from the yeast to drop into a separate
vessel instead of back into A. as shewn in Fig 1.
Fig: 3 shows A. fitted with a skimming board H revolving on the shaft J. and
a collecting vessel B the top of which is of the form of a radial segment of the
surface of the beer in A into which yeast is skimmed by means of H B is raised
and lowered by means of the racks K K and the pinions ii on the shaft I.
Fig 4 is a birdseye view of Fig 3.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is :-
1. The drawing yeast from a vessel adapted for collecting it off the beer in a
fermenting vat or from a trough into which it is falling from cleansing casks, by
means of a force pump and forcing it into filter bags or yeast presses for the
purpose herein described and shewn on the drawings.
2. The different forms of apparatus herein described for the purposes herein set
forth.
