Essex, Brewer. IMPROVEMENTS CONNECTED WITH APPARATUS FOR 'ROUSING'
BEER."
"
This Invention relates to injecting air and carbonic acid gas into beers during
the process of rousing or agitating, to enable the air and gases to mix with the
whole of the beer fermenting in place of pumping in as heretofore.
It consists of four arrangements,
:
First. The application to the ordinary rouser of wood or metal of a plunger
working in a cylinder, which by the attendant pulling a cord in the usual way
gives reciprocating motion, draws the air, aroma, and gases from the top of ferment
and injects them to the bottom of beer, fermenting, agitating the beer at the same
time.
The second arrangement consists of a piece of metal or wood attached to a long
stem or handle, to which is attached a plunger working in a cylinder, so that each
time it is drawn backwards and forwards it injects the air and gases from the top
of ferment to the bottom of beers.
The third arrangement, which is for larger quantities where motive power is
required, consists of a cylinder with a pipe attached reaching to the bottom, on
which is fixed a metal or wood blade. On the top of cylinder is fixed a toothed
wheel, for the purpose of giving motion to the blade below, causing it to revolve for
agitating the beer and distributing the air or gases. At the top of cylinder is a
ΓΗ

page_text: crank and bevil pinion for the purpose of working the plunger and giving motion
to rousers by hand or other motive power.
The fourth arrangement is the ordinary rouser with a tube attached to handle,
for conveying air or gases into beer fermenting by attaching a union hose connected
to a reservoir the gases have been previously put into.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Henry Sorrell in the Great Seal Patent Office on the 10th
May 1879.

This Invention relates to injecting air and carbonic acid gas into beers during
the process of rousing or agitating, to enable the air and gases to mix with the
whole of the beer fermenting in place of pumping in as heretofore.
It consists of four arrangements,-
First. The application to the ordinary rouser of wood or metal of a plunger
working in a cylinder, which by the attendant pulling a cord in the usual way
gives reciprocating motion, draws the air, aroma, and gases from the top of ferment
and injects them to the bottom of beer fermenting, agitating the beer at the same
time.
The second arrangement consists of a piece of metal or wood attached to a long
stem or handle, to which is attached a plunger working in a cylinder, so that each
time it is drawn backwards and forwards it injects the air and gases from the top of
ferment to the bottom of beers.
The third arrangement, which is for larger quantities where motive power is
required, consists of a cylinder with a pipe attached, reaching to the bottom, on
which is fixed a metal or wood blade. On the top of cylinder is fixed a toothed
wheel for the purpose of giving motion to the blade below, causing it to revolve,
for agitating the beer and distributing the air or gases.
At the top of cylinder is a crank and bevil pinion for the purpose of working the
plunger and giving motion to rousers by hand or other motive power.
The fourth arrangement is the ordinary rouser with a tube attached to handle,
for conveying air or gases into beer fermenting by attaching a union hose connected
to a reservoir the gases have been previously put into.
In describing the way my Invention is to be carried out it is necessary to show
four different arrangements, so as to suit large and small quantities, variations in
construction of plant, also as shewn in the fourth arrangement, the necessity of
being able to measure the quantities of air and gas injected, the quantity required
being two cubic feet of gas and two cubic feet of air for every hundred pounds
gravity by Dring and Fages' saccharometer; it is therefore necessary to have an
indicator on piston rod of pump, or the attendant to count the strokes made, or as
shewn in the fourth arrangement, where the pressure guage will indicate the number

page_text: of atmospheres compressed in it, and thus measure the quantity injected, although
a practical brewer, after using the system for some time, will be able to judge by
appearance of head when to leave off; the apparatus should be used as soon as the
fermentation has arrived, and continued according to the quantity and strength of
beers fermenting.
Having described the mode of using, I will now explain the various Drawings.
The first arrangement is shewn in Figure 1, where the iron bowl usually used.
for rousing beers has a tube fixed to it connected to a pump for pumping gas and
air. A pump is shewn in detailed Drawing, Figure 8, the cord to work the same
being pulled over a sheave in the usual manner.
In the second arrangement the barrel of pump is placed on a universal joint that
can be readily attached to a fermenting square or round, the rousing board being.
connected to a hollow stem through which the gases are injected when the handle
is pulled up and down, as shewn in Figure 2.
The third arrangement is for large vessels, where it would not be practicable by.
the first and second arrangements to agitate the bulk sufficiently to aerate the whole
without getting it agitated too much in one place. This arrangement shows a
revolving blade with a perforated tube along it, through which the air and gas is
forced, the pump forcing said gas being worked and moved round, as shewn in
Figure 3.
Fourth is the arrangement where a fixed reservoir is used, the air and carbonic
gas being pumped into it to a pressure shewn by gauge to suit the quantity to be
aerated, the india rubber tube being connected to any of the three arrangements
shewn.
.
A single acting pump is shewn in Figures 1, 2, and 3, and the detailed Drawing,
Figure 8, shews the pump to be used for the several arrangements in double action
form.
Figure 1 represents a square of about 100 barrels, and shows the iron bowl
connected to a hollow piston rod or tube B. This tube is attached to the piston C,
as shown in the detailed Drawing of pump, Figure 8.
At the opposite side or end of the piston is a solid rod D, with a hand line made
fast to it, passing over a sheave E. The piston working in cylinder F draws air in
the downward stroke through the suction pipe G; this pipe is trumpet mouthed,
and is filled with sponge for filtering the air going in. The lower suction pipe H
has also a trumpet mouth, and is brought down close to the head of the ferment;
the upward stroke of the pump draws in carbonic gas and injects the air through
the tube B into the beers, the carbonic gas and aroma of the hop being injected
through the same tube by the downward stroke.
Figure 2 represents a square of about 50 barrels, and shows the land rouser A, a
piece of wood (flat) connected to the hollow stem B, attached to the piston C, with
a solid piston rod D and handle E; the barrel F is on a universal joint, so that when
being used it may be turned from one side to the other. G is the air suction pipe,
and H the suction pipe for carbonic gas.
Figure 3 represents a working round of 150 barrels, and shows the arrangement
for large quantities where power other than manual labour is required.
A is a blade secured to a hollow tube B, B; this tube is attached to the plunger C,
and the latter being connected to the revolving crank D gives reciprocating motion
to plunger and blade. On the shaft E is placed a bevil pinion F working into a
wheel F, fixed to or formed on pump barrel K. Revolving the shaft E gives rotary
motion and reciprocating motion to both plunger and blade, and the pump draws
air in at S, and carbonic gas at H, and injects them at B into the fermenting
worts.
Sheet 2 represents modes of using a reservoir that has had carbonic gas and air
pumped into it. The Figures on this Sheet are drawn on a scale of inch to the
foot; the fermenting vessels, Figures 5, 6, and 7, hold 50, 100, and 150 barrels
respectively, by compressing air and gases into a pressure of 2 atmospheres for 50

page_text: barrels, 4 atmospheres for 100 barrels, and 6 for 150 barrels; it will always insure
the proper quantity being used.
Figure 4 shows a reservoir; A is the pressure gauge; A', the safety valve; C, a
valve with screw for connecting to it any of the hose required to be used, and D is
a tap or valve to which the pump is connected for filling the reservoir.
In Figure 5 E is an iron bowl; B, a hollow stem, with outlet F branched out to
connect hose by the union O; H is the sheave with hand line passing over.
In Figure 6, A is the wood rouser; B, the hollow stem with union O for connect-
ing hose to valve C.
In Figure 7 A is a revolving blade attached to the hollow stem B; C, a stuffing
box for the stem of union D to revolve in when connected to the hose;
E repre-
sents a pair of bevil wheels, which are driven by turning the handle shown on
shaft F.
Figure 8 is a detail Drawing of pump; A is the barrel; D, the piston rod; C,
the plunger, which is double cupped to allow of valve D¹ working between; B, the
hollow piston rod. The air and gases are passed through the passages S, S, S, S, the
valve D¹ covering the lower passages in the upward stroke of the plunger. H is the
valve through which air is drawn, and J the valve through which the carbonic gas
is drawn by the action of the plunger C.
And having now described the nature of my said Invention, and in what manner
the same is to be performed, I declare that I claim,-
Firstly. The construction and employment as herein-before described, and as
shown, of agitators attached to rousers for injecting air and carbonic gas into worts
during fermentation.
Secondly. The formation of double acting pump for injecting contents through
hollow piston rod, as herein-before described, and as shown in Figure 8.
Thirdly. I claim reservoirs used as herein-before described for measuring air and
carbonic gas into worts during fermentation, for mixing carbonic gas and filtered
oxygen to inject into worts during fermentation; also the use of sponge for filtering
the oxygen.
In witness whereof, I, the said William Henry Sorrell, have hereunto set my
hand and seal, this Eighth day of May, One thousand eight hundred and
seventy nine.
