I, DAN RYLANDS of Barnsley in the County of York, Aerated Water Engineer,
do hereby declare the nature of my said invention 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. These improve-
ments overcome the difficulties heretofore experienced from having an excess of water
and gas in the condenser or cylinder from which the soda or aerated water is delivered
to the bottling machines and enables the soda or aerated water apparatus to work
successfully and economically under all conditions. Whonever the pressure in the
condenser or cylinder is in excess, gas or water, or both they are delivered back into
the feed-box, and whenever more gas is received back into the feed-box it passes from
the same back into the gas-holder to be again drawn from thence by the pump.
Fig. 1 is a front elevation of my improved generator and condensing cylinder with
the improvements herein set forth attached thereto. Fig. 2 is a sectional elevation
through line A'B' in Fig. 1 of my improved generator for manufacturing carbonic
acid gas, and Fig. 3 is a sectional elevation through line CD in Fig. 1 of my
improved condensing cylinder or vessel with the saturator enclosed therein used in the
manufacture of aerated waters.
Similar letters of reference indicate corresponding parts in all the figures where
they occur.
A is the generator; B the charging tap; the hopper for whiting in a creamy
state; D the charging pipe; E the discharge pipe; F acid feeder glass containing
acid valve; G the acid tap; H gas-holder; 1 purifier or washer; K gas inlet pipe

page_text: from generator; L pipe covering inlet pipe to convey gas to top of holder; M ontlet
gas-pipe to purifier I: N spring for casing pressure on acid valve; O acid valve
lever P wire attached to lever Ŏ to lift safety-valve; Q chain from regulator to lift
acid valve; R safety-valve; S acid pipe; T plug in hopper C; U agitator; V con-
densing cylinder or vessel mounted on the frame W supported on the standards X,
and is the oscillating pump mounted in the trunnions Z.
The condensing cylinder or vessel V is fitted internally with the saturator p composed
of pipes or tubes disposed on the plate 7. leaving cavities between each pipe or tube.
The pipes or tubes are provided top and bottom alternately with perforations to allow
of the water and gas passing from one tube to another, and up the centre tube to he
delivered above the perforated plate u, from whence they pass through the "glass-
wool or other substance and perforated plates into the lower portion of the
condensing cylinder or vessel V. The aerated water is conveyed from the condensing
cylinder or vessel V to the bottling machines by the pipe .
After carbonic acid gas has been formed in the generator A it passes through the
pipe K to the gas-holder H from whence it is conducted or drawn down the pipe M
and through the washer or purifier I and pipe a to the tap b. The tap bis of the
three-way construction or otherwise to allow of both gas and water being admitted at
once the latter being supplied from the closed feed-box or cistern c through the pipe d,
and delivering such gas and water into the condensing cylinder or vessel V by means
of the pipe e.
Water is supplied to the closed feed-box or sisterne through the pipe
controlled by a valve g operated by the float h. The fresh water is conducted by the
pipe from the tap g to the bottom of the closed feed-box or cistern c. The closed
feed-box or cistern c is provided with the cover wo firmly secured thereon to make a
tight joint to prevent the escape of gas in the space or cavity above the water level
other than to the gas-holder H. The water level in the closed feed-box or cistern c is
kept almost at one uniform height by the action of the float, and is in no way
interfered with by the changing water level in the condensing cylinder or vessel V.
The condensing cylinder or vessel V is furnished with the safety valve j, and when
through a temporary cessation of bottling or other causes the continued working of
the pump accumulates too-much water in the condensing cylinder or vessel V the
safety-valve j opens by the increased pressure and delivers the excess of water and any
surplus pressure of gns through the pipe & into the closed feud-box or cistern c, from
whence the water is drawn back again by the pump, and the gas passes into the gas-
holder to be drawn again by the pump through the washer or purifier I, and both
returned again into the condensing cylinder or vessel V without loss of either water
or gas. The pipe is connected to the closed feed-box or cistern c at a point above
the water level as shown in Fig. 1. The safety valvej is attached to the condensing
cylinder or vessel V, by which, in the case of a temporary cessation of bottling or
other causes, and by the continued working of the pump, both gas and water are
forced through the pipe & to the closed feed-box or cistern c.
k
Gas that is delivered
to the closed feed-box or cistern c passes through the lightly loaded safety-valve m
and the pipe o connected to the pipe M or any other pipe leading into the gas-holder H,
or where found desirable the safety-valve m may be dispensed with and the gas allowed
to pass freely back into the gas-holder H.
The safety valve ; is constructed in the usual manner with a flexible diaphragm
connected to the stem of the valve. The upper portion of the valve casing allows the
stem to move loosely and freely up and down with no attempt at tightness, being
simply guided thereby. The flexible diaphragm forms an impermeable barrier for the
water or gas, which are thus restrained and compelled to flow away through the pipe k
to the closed feed-box or cistern c. The valve is set at the desired water level in
the condensing cylinder or vessel V, which may be accomplished by itself or a pipe
connected to it. The safety-valve m is of similar construction to the valve j, and the
flexible diaphragm forms a barrier for the gas which is thus restrained and coupelled
to pass away through the pipe o to the gas-holder H.
It is important to keep a liberal quantity of gas in the condensing cylinder or
yessel Vas a means of maintaining the pressure and securing a perfect and equal

page_text: saturation of the water with gas which cannot be effected when an excess of water is
accumulated in the condensing cylinder or vessel V. The importance of this has been
so fully recognised that expensive apparatus has hitherto been employed operating by
the weight of the condensing cylinder or vessel when balanced in such a manner as to
cut off the water supply and increase the proportion of gas whenever the water level
tended to rise too-high.
In apparatus constructed in the ordinary manner it often happens that the water is
shut off and the pump then delivers gas alone, the effect of which is that the pump
becomes heated to such an extent as to ruin the leather packings. To obviate this the
pump is sometimes surrounded with a water jacket which reduces the risk from this
source. By means of this invention the necessity for such cumbrous, expensive, and
imperfect devices is entirely avoided, it being obvious that in this apparatus the proper
relative proportions of water and gas are always preserved no matter what variations
are made in the amount of aerated water taken by the bottling machines from the
condensing cylinder.
This invention is equally applicable for charging other liquids, such as Wine, Beer,
etc. with gas.
I wish it to be understood that I do not limit myself to the precise details or con-
figuration 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
Invention and in what manner the same is to be performed I declare that what I
claim is
In combination with a gas-holder 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 safety-valvej attached to the condensing
cylinder or vessel with the pipe & for leading excess of water and gas from the con-
densing cylinder or vessel back to the closed continuous feed-box c, from whence the
water is utilized for charging the condensing cylinder or vessel as required, also the
pipe o connected to the pipe M or any other pipe leading to the gas-holder, with or
without the safety-valve m, for returning gas from the closed feed-box c back to the
gas-holder H, substantially as described for the purpose of maintaining the water-level
and an uniform pressure in the condensing cylinder or vessel V without loss of either
water or gas.
