Improvements in or relating to Apparatus for Manufacturing Aerated
Water Beverages.
1, JAMES MCEWEN of 11 Rushton Street, Hulme, Manchester in the County of
Lancaster, Aerated Water Engineer, do hereby declare the nature of my said inven-
tion and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to apparatus for manufacturing soda-water and other aerated
beverages of the class known as "continuous" in which the carbonic acid gas is
manufactured at ordinary pressure and compressed by a pump, and has for its object
that of efficiently saturating water with gas and supplying the mixture of gas and
water in proper relative proportions under all variations in the amount of aerated
water taken by the bottling machines from the condensing cylinder, at the same time
reserving or utilizing the surplus gas and water for charging the condensing cylinder
as required.
Fig. 1 is a front elevation of my improved generator and condensing cylinder with
my present improvements applied.
A is the generator; B gasometer; C purifier or washer ; D gas inlet pipe from
generator; E gas pipe from the purifier or washer to the tap F of the pump G;
H condensing cylindor or vessel mounted on the frame I supported by the
standards J.
The condensing cylinder or vessel HL is fitted internally with a saturator com-
posed of pipes or tubes disposed on a plate, with cavities between each pipe or
tube, the whole being arranged as indicated and shown in my Specification No. 1140
of 1887 or otherwise as desired.
As carbonic acid gas is generated in the generator A it passes through the pipo D
into the gasometer B, from whence it passes through the purifier or washer (and
pipe E to the tap F. The tap F is of the three-way construction or otherwise to
allow of both gas and water being admitted to the pump G at once.
The water is
supplied from the closed cistern K through the pipe L to the tap F from whence it is
pumped through the pipe M to the condensing cylinder or vessel H. Fresh .water
is supplied to the closed cistern K through the pipe N controlled by the valve O
operated by the float P. Water is conducted from the valve O by the pipe Q and
is delivered at a point considerably below the working water level to prevent
splashing. The closed cistern K is provided with the cover R firmly secured thereon
to make a tight joint to prevent the escape of gas from the space or cavity above
the water level other than to the gasometer B. The water level in the closed cistern K
is kept almost at one uniform height by the action of the float P, and is in no
way interfered with by the changing water level in the condensing cylinder or
vessel H. The closed cistern K is fitted with one or more perforated inverted
dishes S as shown, which fit on the pipe T employed for conveying surplus water
and gas from the condensing cylinder or vessel H. The pipe T is fitted with the
hand regulating screw valve V to allow gas and water to escape from the condensing
cylinder or vessel H when the pump is delivering too-much or in excess of the
requirements of the bottling machines. The outlet pipe W of the blow-back valve U
mounted on the condensing cylinder or vessel H is coupled to the pipe T to allow gas
to escape from the said blow-back valve in case it is lifted by the action of the pump
or pumps. When the pump G is delivering aerated water in excess of the require-
ments of the bottling inachines the screw valve V is regulated by hand to allow the
surplus aerated water to flow back through the pipe T and deliver it under the bottom
inverted dish S, from whence it passes through the perforations which divides or splits
up the same to more effectually saturate the supply water in the closed cistern K; the

page_text: surplus gas rising through the water into the spaco or cavity above the water
line. The surplus gas in the space or cavity above the water level in the closed
cistern K is conveyed by the pipe X into the gasometer B.
By this invention a considerable saving of aerated water and gas is effected, and
by its action or aid the fresh water in the closed cistern K is saturated ; the
surplus gas escaping back to the gasometer, thus saving waste and preventing loss of
gas and aerated water, also assisting to maintain the working water level in the
condensing cylinder or vessel H while the pump is working.
In case of a temporary cessation of bottling or other causes and by the continued
working of the pump, the hand regulating screw valve V is opened by the attendant
to allow both gas and water to escape through the pipe T to the closed cistern K. If
the hand regulating screw valve V is only part open when a temporary cessation of
bottling takes place gas or gas and water will be forced through the blow-back valve U
and pipe Winto the pipe T until such times as the said hand regulating screw valve
is regulated.
Fig. 2 is a part elevation of a horizontal condensing chamber showing how the
hand regulating screw valve V, pipe T, and the pipe W from the blow-back valve U
are attached. In this arrangement the pipe T is coupled to the underside of the
condensing cylinder or vessel H.
I wish it to be understood that I do not limit myself to the precise details or
configuration of the parts I have shown and described as the same may be varied or
modified in adapting it to the various kinds of aerated water machinery without
departing from the principle and object of my said invention.
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 1
claim is :-
:-
1. In combination with a gasometer and condensing cylinder or vessel and their
adjuncts employed in the manufacture of aerated waters the use construction and
arrangement of the hand regulating screw valve V and pipe T for leading excess
of water and gas from the condensing cylinder or vessel H to the closed cistern K,
substantially as described and as illustrated.
2. In combination with a gasometer and condensing cylinder or vessel and their
adjuncts employed in the manufacture of aerated waters the use construction and
arrangement of apparatus consisting of the hand regulating screw valve V, pipe T,
and the outlet pipe W from the blow-back valve U attached to the pipe T, for leading
or conveying excess of water and gas from the condensing cylinder or vessel H to
a point below the inverted perforated dish or dishes S disposed in the closed cistern
or continuous feed-box K, through the perforations of which water and gas pass
so as to thoroughly saturato the water in the closed cistern, from whence the
saturated water is utilized for charging the condensing cylinder or vessel as required,
substantially as described for utilizing surplus water and gas and for maintaining the
water level and an uniform pressure in the condensing cylinder or vessel H without
loss of either water or gas.
3. In combination with the closed cistern or continuous feed-box K the use of the
perforated dish or dishes S for the purpose specified.
