Southampton Buildings, London, "IMPROVED APPARATUS FOR FACILITATING THE
DISPENSING OR DRAWING OF EFFERVESCENT OR GASEOUS LIQUIDS [A commu-
nication to him from abroad by Louis Bergen of the City and State of New
York, United States of America.]
The object of these improvements is to provide for relieving effervescent liquids,
such for instance as ale, beer, porter and stout, of a portion of the gas with which
they are impregnated before dispensing the same so as to facilitate and expedite
the dispensing thereof.
According to the said improvements I combine in an apparatus for dispensing
effervescent or foaming liquids, two compartiments, a pipe leading to one compart-
ment from the receptable containing the liquid, a pipe or passage connecting this
compartment and the other compartment directly together, and provided with a
valve whereby the gas may be allowed to escape from the former compartment to
the latter compartment, and an escape from the compartiment last named to the
atmosphere. When liquid is to be dispensed without relieving it of any gas the
dispensing faucet is opened and the liquid runs off as usual, but when it is
desirable to relieve the liquid of gas it is allowed to flow into the first compart-
ment, then the communication between this compartment and the receptacle is cut

the other compartment is opened so that the gas can escape into the latter and
subsequently the escape is opened to permit the gas to pass off into the
atmosphere.
The said improvements also comprise the combination in an apparatus for
dispensing effervescent or foaming liquids, of two compartments arranged one
above the other, a pipe leading to the lower from the receptacle containing the
liquid, a pipe or passage connecting the two compartments directly together and
provided with a valve whereby gas may be allowed to escape from the lower com-
partment into the upper compartment, and an escape cock arranged on the upper
compartment.
The said improvements also comprise the combination in an apparatus for
dispensing effervescent or foaming liquids, of two compartments, a partition between
the same capable of movement by inflowing liquid, a pipe leading to one compart-
ment from the receptacle containing the liquid, a valve controlling communication
between this compartment and the other compartment, and an escape from the
compartment last named.

WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, & C° Patent Agents,
Southampton Buildings, London. "IMPROVED APPARATUS FOR FACILITATING THE
DISPENSING OR DRAWING OF EFFERVESCENT OR GASEOUS LIQUIDS."-A commu-
nication to me from abroad by Louis Bergen, of the City and State of New
York, United States of America.
The object of this invention is to provide for relieving effervescent liquids, such
for instance as ale, beer, porter and stout, of a portion of the gas with which they
are impregnated, before dispensing the same, so as to facilitate and expedite the
dispensing thereof.
The said invention partly consists in the combination of two compartments, a
pipe leading to one compartment from the receptacle containing the liquid, a pipe
or passage connecting this compartment and the other compartment directly
together, and provided with a valve whereby the gas may be allowed to escape
from the former compartment to the latter compartment, and an escape from the
compartment last named to the atmosphere. When the liquid is to be dispensed
without relieving it of any gas, the dispensing faucet is opened and the liquid runs
off as usual, but when it is desirable to relieve the liquid of gas, it is allowed to
flow into the first compartment, then the communication between this compartment
and the receptacle is cut off, next the valve controlling communication between the
said compartment and the other compartment is opened, so that gas can escape into
the latter, and subsequently the escape is opened to permit the gas to pass off into
the atmosphere.
It further partly consists in the combination of two compartments arranged one
above the other, a pipe leading to the lower from the receptacle containing the
liquid, a pipe or passage connecting the two compartments directly together and
provided with a valve whereby gas may be allowed to escape from the lower com-
partment into the upper compartment, and an escape cock arranged on the upper
compartment.
It further partly consists in the combination of two compartments, & partition
between the same capable of being moved by inflowing liquid, a pipe leading to one
compartment from the receptacle containing the liquid, a valve controlling com-
munication between this compartment and the other compartment, and an escape
from the compartment last named.
In the accompanying drawing.
Figure 1 is a central vertical section of apparatus embodying the said invention
Figure 2 is a central vertical section of apparatus of modified form; and
Figure 3 is a central vertical section illustrating another modification. Similar
letters of reference indicate corresponding parts in all the figures.
Referring first to Figure 1, A and B indicate two compartments, with the lower
of which communicates a pipe C leading from the receptacle containing the beer or
other liquid to be drawn. Communication between this pipe C and the compart-
ment B is controlled by a cock D. E indicates a faucet with which the compartment B
is furnished. It affords provision for dispensing or drawing off the liquid from the
compartment B. Communication between the two compartments is afforded by a
pipe or passage F controlled by a cock or valve F with which it is provided. The
upper compartment A is provided with an. escape G which, as here shown, is made
in the form of a cock, so that it may be opened and closed at pleasure.

page_text: If it is desired to draw the liquid without relieving it of any gas, the cock D
and faucet E are opened and the liquid is allowed to flow directly from the pipe C
through the compartment B and thence to the faucet E. If, however, it is desirable
to relieve the liquid of any gas, the cock D is opened to allow the liquid to flow
into the compartment B and then closed. The valve F¹ is then opened and gas
rises from the liquid into the compartment A. Subsequently the cock G is opened,
and the gas escapes from the compartment A to the atmosphere. The faucet E is
now opened and the liquid can be drawn off quietly.
In the apparatus shown in Figure 2 the compartments A and B are separated by
a movable piston or partition H. When the liquid flows from the pipe C into the
compartment B it raises the piston or partition H into contact with a flange I
forming a stop to limit its motion. When that occurs a valve F¹ controlling a
passage F in the piston or partition is opened, and gas rises into the upper com-
partment A. The gas may be allowed to pass from the upper compartment by
opening the escape or cock G. The valve FI as here shown is operated by rotating
its stem F2 within a screw-threaded socket J. This stem F2 is swivelled to the
valve F so that it may be turned without imparting a rotary movement to the
said valve. The stem of the valve extends upwards through a hollow rod H' with
which the piston or partition H is provided. This rod H¹ passes through a stuffing-
box a with which the top of the compartment A is furnished. The screw-threaded
socket J is affixed to the interior of the rod H¹ near the upper end;
it may
secured in place by screw threads as shown, or by other suitable means. The stem
of the valve F¹ may be turned by means of a key fitted into an angular cavity b
in the stem. A sleeve K of india-rubber fitting over the adjacent ends of the
valve F and the socket J precludes leakage around the valve F' through the piston
or partition H.
be
In Figure 3 I have shown two compartments A and B similar to those shown in
Figure 1, and connected by a pipe or passage F controlled by a valve F¹. The
compartiment A has an escape G. This apparatus also comprises a compartment L
which is connected with the compartment A, by a pipe or passage F controlled by a
valve F¹. The compartment L is closed and has no escape. When it is desired
to relieve the liquid to be drawn from any gas, the valve F' of the pipe or passage F
which leads to the compartment L is opened and gas is thereby permitted to escape
into the compartment L. If it is desired to allow still more gas to escape, the
valve F of the pipe or passage F which leads to the compartment A is opened to
allow gas to enter this compartment. Subsequently the valve F' controlling the
passage of gas to this compartment will be closed, and its escape G will be opened
to let the gas pass from the compartment to the atmosphere. After, the desired
amount of liquid is drawn from the compartment B the gas admitted to the com-
partment L may be allowed to pass back to the compartment B by opening the
valve F¹ which controls communication between these compartments. This will be
advantageous because the gas will freshen and keep fresh the liquid remaining in
the compartment B. Obviously the compartments A and B of this apparatus may
be used like the apparatus shown in Figure and the compartment L may be left
unused when desirable. In the use of the forms of apparatus shown in Figures 1
and 2 the gas admitted to the compartment A may, whenever desirable, be returned
to the liquid remaining in the compartment B, instead of being allowed to escape into
the atmosphere. As gas may be allowed to escape from liquid quietly by means
of my improvements the liquid when dispensed will contain more gas than
ordinarily.
.
In all the forms of apparatus shown I prefer to arrange the faucet E considerably
above the bottom of the compartment B. Apparatus having any desired number
of compartments may be made.
The compartments of the various forms of apparatus may be made of sheet metal
and in the manner ordinarily pursued in making articles of such material. The
other parts may also be made of metal.
It is obvious that the apparatus may be considerably modified without departing

page_text: from the nature of this invention, and that it may be made of various ornamental
shapes and materials. I may so combine the cocks and valves as to reduce the
number of manipulations necessary to operate the apparatus, and arrange them
where they can be most conveniently reached. In the apparates shown in Figure 2
I preferably provide the under side of the flange I, with a washer of packing
material and the under side of the partition H with a cup-packing of leather, india-
rubber or like material
Having thus fully described the said invention as communicated to me by my
foreign Correspondent, and the manner of performing the same, I wish it understood
that I claim in apparatus for facilitating the dispensing or drawing of effervescent
or gaseous liquids.
First. The combination of two compartments, a pipe leading to one compartment
from the receptacle containing the liquid, a pipe or passage connecting this com-
partment and the other compartment directly together and provided with a valve
whereby the gas may be allowed to escape from the former compartment to the
latter compartment, and an escape from the compartment last named to the
atmosphere, substantially as specified.
Second. The combination of two compartments arranged one above the other, a
pipe leading to the lower from the receptacle containing the liquid, a pipe or passage
connecting the two compartments directly together and provided with a valve
whereby gas may be allowed to escape from the lower compartment into the upper
compartment, and an escape cock arranged on the upper compartment, substantially
as specified.
.
Third. The combination of two compartments, a partition between the same
capable of being moved by the inflowing liquid, a pipe leading to one compartment
from the receptacle containing the liquid, a valve controlling communication between
this compartment and the other compartment, and an escape from the compartment
last named, substantially as specified.
In Witness whereof I the said William Robert Lake have hereunto set my
hand and seal this Ninth day of March in the year of Our Lord one
thousand eight hundred and eighty three.
