Apparatus for Carbonating and Dispensing Liquids.
I, HENRY BIRKBECK, of the Firm of Tongue & Birkbeck, of 31, Southampton
Buildings, Chancery Lane, London, W.C., Fellow of the Chartered Institute of
Patent Agents, do hereby declare the nature of this invention (a communication
to me from abroad by The Diamond Soda Water Manufacturing Company, of
the City, County, and State of New York, United States of America), to be as
follows:-
This invention relates primarily to improved means for carbonating water or
other liquid or in other words of mixing water with gas such as carbonic acid
gas; and the invention also relates to improvements in an apparatus whereby the
liquid and gas can be properly commingled and a supply kept constantly on hand
with very little trouble.
This invention has for its object to do away with the employment of a number
of gas holders for supplying fountains where carbonized liquids are dispensed
and to provide an apparatus for the carrying out of the process of carbonizing
which will be an adjunct of the dispensing fountain and with which the water
or other liquid can be carbonized at will and as wanted.
Briefly according to this invention the gas in starting the carbonating operation
is allowed to pass from the gas tank under a regulated pressure into a suitable
chamber from whence it is allowed to pass to a force pump where the gas and
water from a suitable source of supply are allowed to commingle the gas passing
from the carbonating chamber into the pump under a pressure advantageously
about equal to the pressure of the head of water. The gas and water are then
forced by the pump back into the carbonizing chamber where the water is sprayed
or split up in fine particles settling at the bottom of the chamber, the gas free-

ing itself from the water and settling at the top of the said chamber.
completes the first or initial step in the carbonizing process at which time there
may or may not be enough carbonized water in the chamber for use but to
more thoroughly charge the water and to provide a supply sufficiently large pro-
ceed as follows:
-
The force pump is again operated the free gas in the carbonizing chamber
again passing or being drawn into the pump there commingling with a fresh
supply of water and is again forced by the pump back into the said chamber
being again split up and by repeating this operation the primary charge or
residue of the charge of gas in the chamber may be repeatedly drawn off and
commingled with a fresh supply of water thoroughly carbonizing the water and
avoiding the necessity of using a fresh supply of gas for a fresh supply of
water. The practising of this part of this invention has many other advantages in
part hereinafter referred to.
The apparatus by means of which this invention may be practised consists in
a mixing or storage chamber or cylinder adapted to be connected with a gas
holder a pump connected with said chamber or cylinder by two pipes one of
which is adapted to convey gas to a chamber in the pump the other of which

page_text: pipes is adapted to convey a mixture of gas and liquid to the main chamber or
cylinder from said pump and means for supplying the chamber of said pump with
water and suitable valves are provided for regulating the passage of gas and liquid
to the pump and its passage therefrom to the main cylinder. Suitable valves
and a gas pressure indicator are arranged between the gas holder and the main
cylinder whereby the supply and pressure of the gas to the latter can be
regulated; and like devices are also provided whereby the pressure under which
the gas passes to the pump cylinder may be regulated.
The invention further consists in the novel details of improvement and the
combination of parts that will be more fully hereinafter set forth.
The said cylinder or carbonating chamber which I will term the cylinder No. 1
is of any suitable construction and may be supported in any suitable manner;
the gas holder or cylinder No. 2 being connected with the cylinder 1 by a pipe
that opens into the upper part of the cylinder 1; a suitable gas pressure indicator
and regulator being interposed in said pipe between the holder and cylinder 1;
a valve No. 1 being, provided in said pipe between the holder and the indicator
and a No. 2 valve in said pipe between said indicator and the cylinder 1. With
this arrangement when No. 1 valve is opened and valve No. 2 closed the indicator
will show the gas pressure in the holder and when valve No. I is closed and
No. 2 valve opened the indicator will show the gas pressure in cylinder 1 When
both of said valves are opened gas may pass from the holder into cylinder 1.
A valve No. 3 is connected with cylinder 1 and with said pipe whereby the
latter can be disconnected from cylinder 1 if desired without permitting the
escape of gas from cylinder 1.
Another pipe leads from cylinder 1 to an ice box or cooler a coil of pipe being
preferably located in said box and connecting this pipe No. 2 with a dispensing
faucet.
A valve No. 4 in this pipe regulates the passage of the carbonated water from
cylinder 1. A No. 3 pipe or tube within cylinder 1 leads from pipe No. 2 to the
lower part of cylinder 1 to conduct the carbonated liquid to pipe No. 2.
A pipe No. 4 connects the upper area of cylinder 1 with a pump of suitable
construction a valve No. being placed in this pipe to regulate the passage of
gas from cylinder 1 to said pump; this valve being advantageously an automatic
regulator valve arranged to permit the passage of gas after the latter has reached
a certain pressure. A suitable safety valve may be provided in cylinder 1.
The pump advantageously has a chamber to which the pipe No. 4 leads; dupli-
cate valves being arranged to permit gas to pass from the pipe No. 4 into said
pump chamber but to prevent it from passing back into said pipe
A pipe No. 5 leads from the cylinder 1 to the said pump chamber duplicate
valves being arranged in the said chamber to prevent gas from passing into said
chamber through pipe No. 5 but arranged to permit liquid and gas to be forced
through said pipe from said pump chamber to cylinder 1.
A valve No. 5 in pipe No. 6 regulates the flow of gas and liquid into or from
cylinder 1 and the chamber of the pump is connected by a pipe No. 7 with a
water main or other source of supply advantageously provided with a water meter
and a filter and a valve all connected with pipe No. 7. As before stated the
pump may be of suitable construction but advantageously so arranged that when
its piston is operated by a lever or otherwise in either direction a charge of gas
from cylinder and a charge of water from pipe No. 7 will be drawn into the
said pump chamber and will be mixed therein and forced by the pump through
pipe No. 5 into cylinder 1 as hereinafter described.
To accomplish this result the pump is advantageously constructed as follows:-
A piston works in the usual cylinder the piston rod passing through a packing
in the usual way the rod having a ring which engages with a stud on the afore-
said pump lever.
The pump cylinder opens into the pump chamber at one end which chamber is
divided by a septum into two compartments the top of the chamber having an

page_text: integral roof provided with apertures which opens into the compartments above
which lie the duplicate valves formed from a sheet of rubber fabric and weighted
in the usual manner.
A by-pass is formed with the pump cylinder which connects at one end with
the pump cylinder and at the other end with one of the said compartments in the
pump chamber so that by one stroke of the piston in either direction the gas and
water in either of the compartments will be forced through the respective valve
into the pipe No. 5 and thence into cylinder 1.
In order to make a good construction and to properly connect each of the said
compartments with the source of supply and exit two clamps are provided having
an apertured roof the apertures of which lead into the said compartments and
over which valves are seated which apertures also lead into or from a commingling
chamber formed in the clamp from which latter chamber leads a threaded nipple
which connects with the water supply pipe No. 7 and a further nipple which leads
to the gas supply pipe No. 4.
The upper clamp is also provided with a chamber from which extends a nipple
which connects with the pipe No. 5 and in which its valves lie-the aforesaid
compartments opening into this chamber.
Both of the clamps are provided with ears through which pass bolts for securing
the clamps down on the pump chamber each of the clamps having recessed seats
in which the rubber fabric of the valves is held.
A stand having nipples supports the pump cylinder which is also provided with
nipples through both of which nipples bolts pass to hold the pump on the stand.
The double acting force pump thus formed enables the commingled gas and
water to be forced back into the cylinder 1 very rapidly; and thereby is secured
this advantage as well as the employment of the said commingling chamber dis-
tinct from the pump chamber but it is apparent that other forms of force pumps
can be employed without altering the nature of this invention the only essentials
in this regard being a receiving or commingling chamber suitable check valves
and a force pump.
In order to enable the liquid that passes into cylinder 1 through the pipe No. 5
to be distributed in one or more thin sheets and be more readily mingled with
the gas in the upper area of the cylinder 1 there is provided an inlet nozzle or
tube which is located within the cylinder 1 and connected with pipe No. 5. The
said inlet nozzle is in the form of a tube having its lower end closed and one
side wall provided with one or more narrow slits.
One slit may be horizontally arranged and the other slits are segmental and
respectively upwardly and downwardly inclined. This arrangement of the slits
causes the liquid to issue from the said inlet nozzle or tube in one or more
thin sheets or the slits may be otherwise arranged so that the sheets of liquid
issuing therefrom will be broken up and cause the liquid and gas in cylinder 1
to intimately commingle.
A suitable water gauge is connected with cylinder 1.
The operation of the apparatus may be described as follows:-
The parts being connected together the valves are opened so as to allow gas
from the holder to pass into cylinder under the desired pressure and to the
desired volume; and when the desired volume of gas is in the cylinder 1 the
No. 3 valve is closed and kept closed during the carbonating process.
Valves Nos. 4 and 5 are then opened whereby gas from cylinder 1 may pass to
said pump chamber the valves preventing the gas from passing to said chamber
through No. 5 pipe.
The valve is also opened to allow water to pass to said pump chamber where
the gas and water commingle in a measure.
The pump is now operated and when the piston is moving in one direction
draws the gas and water into said pump chamber where they will mix; and when
the piston moves in the opposite direction the gas and air in said pump chamber
is caused to commingle by the pressure applied by the piston and the mixture

page_text: of gas and liquid are forced from the pump through pipe No. 5 into cylinder 1.
The carbonated liquid passes from said inlet nozzle in thin sheets which by the
inclination given the slits will be broken up into fine particles and passing
through the upper area of the cylinder absorbs more gas and finally falls to the
bottom thereof. There should be an excess of gas in cylinder 1 over the liquid
therein so that the gas can continually be drawn from cylinder 1 into the pump
during the operation. After a sufficient quantity of liquid has been commingled
with gas and passed into cylinder 1 the pump can be stopped and the necessary
valves closed to retain the carbonated liquid in cylinder 1. The draw-off valve
can then be opened and the carbonated liquid drawn off as desired which valve
may be kept open during the carbonating process to allow of a quantity of the
carbonated liquid to be cooled in the coil
This operation by being repeated that is by continually using the same volume
of gas in the cylinder over and over to carbonate a fresh supply of water
thoroughly carbonates the water in the cylinder 1 the volume of which can be
determined by the gauge and the safety valve prevents too great a pressure being
generated in the cylinder.
It is evident that if it is desired to produce the carbonated liquid in quantity
for storage the necessary valves can be kept open as much as desired and the pump
kept working so that the carbonated liquid can be drawn off from the cylinder 1
as fast as it is produced.

The invention further consists in the novel details of improvement and the

and then pointed out in the claims.

In the accompanying drawings in which similar letters and numerals of refer-
ence indicate corresponding parts in the several views the number 1 indicates a
cylinder or carbonating chamber of suitable construction which may be sup-
ported in any suitable manner.
2 is a gas-holder or cylinder connected with the cylinder 1 by a pipe 3 that.
opens into the upper part of cylinder 1.

page_text: 4 is a suitable gas-pressure indicator and regulator interposed in pipe 3 between
the holder 2 and cylinder 1.
At 5 is a valve in pipe 3 between the holder 2 and indicator 4, and 6 is a valve
in pipe 3 between said indicator and the cylinder 1. With this arrangement
when valve 5 is opened and valve 6 closed the indicator 4 will show the gas pres-
sure in holder 2 and when valve 5 is closed and valve 6 opened the indicator will
show the gas-pressure in cylinder 1. When both of said valves are opened gas
may pass from holder 2 into cylinder 1.
At 7 is a valve connected with cylinder 1 and with pipe 3 whereby pipe 3 can
be disconnected from cylinder 1 if desired without permitting the escape of gas
from cylinder 1.
At 8 is a pipe which leads from cylinder 1 to an ice-box or cooler 9, a coil of
pipe 8 being advantageously located in said box and connecting the pipe 8 with
a dispensing faucet 10.
At 11 is a valve in pipe 8 to regulate the passage of the carbonated water from
cylinder 1.
At 12 is a pipe or tube within cylinder 1 and which leads from pipe 8 to the
lower part of cylinder 1 to conduct the carbonated liquid to pipe S.
At 13 is a pipe which connects the upper area of cylinder 1 with a pump 14
of suitable construction a valve 15 being placed in the pipe 13 to regulate the
passage of gas from cylinder 1 to the pump 14, the valve 15 being advantageously
an automatic regulator-valve arranged to permit the passage of gas after the
latter has reached a certain pressure.
At 16 is a suitable safety-valve in cylinder 1.
The pump 14 which is advantageously constructed as shown has a chamber 17
to which the pipe 13 leads duplicate valves 17ª being arranged to permit gas to
pass from the pipe 13 into said chamber but to prevent it from passing back into
said pipe.
At 18 is a pipe that leads from the cylinder 1 to the chamber 17 of pump 14
duplicate valves 19 being arranged in the chamber 17 to prevent gas from passing
into chamber 17 through pipe 18 but arranged to permit liquid and gas to be
forced through said pipe from chamber 17 to cylinder 1.
At 20 is a valve in pipe 18 to regulate the flow of gas and liquid into or from
cylinder 1 and the chamber 17 of pump 14 is connected by a pipe 21 with a water
main or other source of supply, 22 being a water meter, 23 a filter and 24 a valve
all connected with pipe 21.
As before stated the pump 14 may be of suitable construction; but advantage-
ously so arranged that when its piston a is operated by the lever 14" or other-
wise in either direction a charge of gas from cylinder 1 and a charge of water from
pipe 21 will be drawn into chamber 17 and will be mixed therein and forced by
the pump through pipe 18 into cylinder 1 as hereinafter described. To accom-
plish this result the pump is advantageously constructed as follows:.
At b is the usual cylinder in which works the piston a the piston rod c passing
through the packing d in the usual way, the rod having the ring e which engages
with a stud f on the lever 14. The cylinder b opens into the chamber 17 at
one end which chamber is divided by a septum g into two compartments hi the
top of the chamber having an integral roof j provided with apertures k¹ which
open into the compartments hi above which lie the duplicate valves 19 formed
from a sheet of rubber fabric and weighted in the usual manner.
At m is a by-pass formed with the cylinder b which connects at one end with
the cylinder by means of the port n and at the other end with the compart-
ment in the chamber 17 so that by one stroke of the piston a in either direction
the gas and water in either of the compartments hi will be forced through the
respective valve 19 into the pipe 18 thence into cylinder 1.
In order to make a good construction and to properly connect each of the
compartments hi with the source of supply and exit two clamps are pro-
vided, clamp p¹ having an apertured roof p³ the apertures 17b of which lead into

page_text: the compartments hi and over which the valves 17 are seated, which aper-
tures 176 also lead into or from a commingling chamber a formed in the clamp
from which latter chamber leads a threaded nipple g¹ which connects with the
water supply pipe 21 and a further nipple q which leads to the gas supply
pipe 13. The upper clamp p is also provided with a chamber from which extends
a nipple which connects with the pipe 18 and in which the valves 19 lie, the
compartments hi opening into the chamber.
Both of the clamps pp are provided with ears s through which pass bolts t for
securing the clamps down on the chamber 17 each of the clamps having recessed
seats in which the rubber fabric j' & 1 of the valves is held.
A stand A having nipples B supports the cylinder b which is also provided
with nipples C through both of which nipples bolts D pass to hold the pump on
the stand.
The double-acting force pump thus formed enables the commingled gas and
water to be forced back into the cylinder 1 very rapidly and the construction
shown secures this advantage as well as the employment of the commingling
chamber distinct from the chamber 17; but it is apparent that other forms of
force pumps can be employed without altering the nature of my process the only
essentials in this regard being a receiving or commingling chamber, suitable
check-valves, and a force pump.
In order to enable the liquid that passes into cylinder 1 through pipe 18 to be
distributed in one or more thin sheets and be more readily mingled with the
gas in the upper area of the cylinder 1, I have provided an inlet nozzle or tube 25,
which is located within the cylinder 1 and connected with pipe 18. (See Fios. 2
to 7). The nozzle 25 is in the form of a tube having its lower end closed and
one side wall provided with one or more narrow slits 26 20. The slit 26 is shown
horizontally arranged and the slits 26 are segmental and respectively upwardly
and downwardly inclined. This arrangement of the slits causes the liquid to issue
from the tube 25 in one or more thin sheets and when the slits 26 26 are arranged
as shown in Figs. 2 to 7 inclusive the sheets of liquid issuing therefrom will be
broken up and cause the liquid and gas in cylinder 1 to intimately commingle.
At 27 is a suitable water gauge connected with cylinder 1.
The operation of the apparatus may be described as follows:-
The parts being connected together as shown in Fig. 1, valves 5, 6 and 7 are
opened so as to allow gas from holder 2 to pass into cylinder 1 under the desired
pressure and to the desired volume and when the desired volume of gas is in the
cylinder 1 the valve 7 is closed and kept closed during the carbonating process.
Valves 15 and 20 are then opened whereby gas from cylinder 1 may pass to
chamber 17 (or q) of pump 14, the valves 19 preventing the gas from passing to
chamber 17 (or hi) through pipe 18.
The valve 24 is also opened to allow water to pass to chamber 17 (or q) of
pump 14 where the gas and water commingle in a measure. Pump 14 is now
operated and when the piston is moving in one direction draws the gas and water
into chamber 17 (or hi) where they will mix and when the piston moves in the
opposite direction the gas and air in chamber 17 (or hi) are caused to commingle
by the pressure applied by the piston and the mixture of gas and liquid is forced
from the pump through pipe 18 into cylinder 1. The carbonated liquid passes
from nozzle 25 in thin sheets which by the inclination given the slits will be
broken up into fine particles and passing through the upper area of the cylinder
absorbs more gas and finally falls to the bottom thereof. There should be an
excess of gas in cylinder 1 over the liquid therein so that the gas can continually
be drawn from the cylinder 1 into pump 14 during the operation.
After a sufficient quantity of liquid has been commingled with gas and passed
into cylinder 1 the pump can be stopped and valves 15, 20, and 24 closed to retain
the carbonated liquid in cylinder 1. Valve 11 can then be opened and the car-
bonated liquid drawn off as desired which valve may be kept open during the
carbonating process to allow of a quantity of the carbonated liquid to be cooled

page_text: in the coil. This operation by being repeated—that is by continually using the
same volume of gas in the cylinder 1 over and over again to carbonate a fresh
supply of water-thoroughly carbonates the water in the cylinder 1 the volume
of which can be determined by the gauge 27 and the valve 10 prevents too great
a pressure being generated in the cylinder.
It is evident that if it is desired to produce the carbonated liquid in quantity
for storage the valves 5, 6, 7, 15, 20, and 24 can be kept open as much as desired
and the pump kept working so that the carbonated liquid can be drawn off from
the cylinder 1 as fast as it is produced.
