Improvements in Machinery and Appliances for or connected with
the Dispensing of Aerated Water.
I, JOHN PERKINS JACKSON of 63 Duke Street Liverpool, Engineer, do hereby
declare the nature of this Invention to be as follows:--
My improved apparatus consists of a counter fountain or pillar for the dispensing
of aerated water, in which the mechanism for lifting up a bottle or glass may be
dispensed with, and I fix instead a cylindrical glass or measure to the apparatus itself.
I also have an arrangement to register the number of glasses supplied by the apparatus.
In the front of it
The fountain consists of a pillar er standard to fix on the counter.
about half way up on a suitable bracket attached to or forming part of the pillar is
the glass cylinder or measure which I preferably make of about the size of a half pint
glass. This glass is supported at its top and bottom open ends by dises of metal
between which it is firmly held. These discs are held together either by outside
stays or supports or by one internal stay.
On the bottom base plate or disc is the outlet valve which allows the aerated water
in the measure to flow out into a glass beneath when the projecting end of the valve
spindle (kept in position by a strong internal spiral spring) is pressed. Above this
outlet valve on the top disc is the connection for the aerated water from the cylinder
and also the inlet valve the spindle of which has similarly a projecting end, which
on being pressed allows the aerated water from the cylinder to pass to the interior
of the glass measure.
On the other side, usually, of the top plate is the snift valve consisting of a spring
valve placed preferably in a vertical position and usually screwed into the top plate
of the measure. The end of the valve spindle projects outside its casing and when
the handle operating the valve is pressed downwards the valve is opened and the air
confined inside the measuring chamber is allowed to pass out, the lower part of the
valve spindle being made hollow or with a groove in it for that purpose.
Below the lower end of the snift valve spindle on a level or higher than the top
of the fluid when the measure is full, is another valve seating which forms the
top of a valve cage. Inside this cage which. bas an open bottom is a hollow rubber
ball or other floating valve and as the liquid in the measuring chamber rises and has
at last filled the chamber it closes this valve also and so cannot pass out to soil the
machine or be wasted. When the valve spindle is ordinarily pressed down and
descends only a little it does not touch this lower valve but when pressed down to
its fullest extent it pushes the lower valve off its seating and so opens communication
to the outer air.
The inlet and outlet valves are opened and shut alternately in the following way.
On the counter pillar or on a bracket attached to it is pivotted a disc. This disc is
hung between and against the upper and. lower aerated water valves and in such a
manner as to be able to operate them both. For this purpose on the inner side of the
disc are fixed two cams or the surface of the disc is itself so shaped as to form two
cams. As the handle attached to the disc is pulled forward, the disc also turns, the
upper cam comes into play and opens the top aerated water valve.
The bandle is then pushed back again, the top valve is released and directly after-
wards the lower cam begins to act and the lower valve is opened. The disc has on
the same side as the cams a projecting rim or edge so as to prevent anything being'
pushed between the valves and the disc cams and the valves being so irregularly
opened.
At or about the top of the pillar is an apparatus to register the number of times
that a customer is served. It is operated by the disc already described which carries

page_text: on its outer edge or periphery nearest the pillar a set of teeth or cogs.
into a rack which slides up and down inside the pillar.
These gear
The registering apparatus consists of a small oblong box or case. In this, running
from back to front are three horizontal parallel spindles which counting from right to
left we will call C B and A. All these spindles turn freely in their bearings or
sockets and each carries at its front end a dial plate, the C dial being for units, the B
for tens, and the A for hundreds, or the apparatus can if desired be made to register
pounds shillings and pence and the dial plates then be marked accordingly. The
front of the casing is so cut away that only one figure on each of the dial plates can
be seen at a time and the dial plates being properly set to start work the number of
glasses registered can then at any time be read off.
The C spindle carries for a portion of its length towards its back or far side a loose
collar or outer spindle and this collar has fixed to it a cog wheel (No. 1) actuated by
the rising and falling rack already mentioned. Close alongside this No. 1 cog wheel
but fixed on the spindle C itself is a ratchet wheel. The No. 1 cog wheel has
projecting from its front side a stud or bracket carrying a pawl which gears into the
ratchet wheel alongside of the No. i cog wheel. It will thus be seen that when the
rack rises it turns the No. 1 cog wheel which itself as it turns operates the ratchet
wheel and makes that and the dial plate turn and register !. It does this by moving
the dial so that the figure 0 shewing through the cut away part in the front of the
box gives place to the figure 1, the dial being marked from 0 to 9 and each rise of
the rack being sufficient to make it turn one tenth of its radius. As the rack descends
again it moves the No. 1 cog wheel backwards and the pawl attached then glides over
the teeth of the ratchet wheel and does not operate the rest of the mechanism. If
desired an extra pawl can also be fitted say to the bottom of the box to prevent the
possibility of the ratchet wheel being moved back but there should then be a lever or
other arrangement to allow the controller of the apparatus to throw this second pawl
out of gear when he wishes to set the apparatus anew.
In
The details so far given relate to the spindle C and the registration of units.
order to carry forward the registration to tens and hundreds I place on spindle C
between the ratchet wheel and the dial plate a disc (No. 2) secured to the spindle and
carrying a single tooth on its outer periphery. On spindle B and secured to it I fix a
disc No. 3 also with a similar single tooth. This disc carries on its rear side a circle
of 10 projecting pins or studs equi-distant from one another and forming a complete
circle. The disc No. 3 is set a little in front of disc No. 2 so that the tooth of No. 2
may gear into and operate the teeth of No. 3. Thus for every complete revolution
that No. 2 makes it moves No. 3 disc one degree or one tenth of a revolution, by
which means while dial plate C registers all the units, dial plate B registers all
the tens.
On spindle A is a disc No. 4 without a tooth but with pins or studs like No. 3 and
it is set relatively to and operated by No. 3, the same as No. 3 is set and operated
by No. 2.
No. 4 moves one tenth of a revolution for every complete revolution of
No. 3 and so correctly registers the hundreds. In order to entirely prevent No. 3
and No. 4 disc moving backwards when out of gear I either pivot their spindles rather
tightly or I fix to each spindle a ratchet wheel or I cut ratchets on the discs themselves
and cause a pawl to gear into each ratchet wheel to prevent backward movement.
The action of the apparatus is as follows:-
I place the glass to be filled under the outlet of the measuring chamber and I pull
forward the handle attached to the disc. As I do so the registering apparatus above
marks 1, the top aerated water valve is opened and the aerated water from the
cylinder streams into the glass measure. When about half full the snift valve is
slightly depressed, the confined air and gas are let out and the measure then fills up
rapidly with aerated water. The snift valve can again if required be depressed so as
to allow the measure to quite fill with water, it cannot overflow for as soon as full
the floating valve rises and shuts off the exit or overflow outlet. The handle of the
disc is now pushed back again, the rack descends into its original position, the top
aerated water valve closes and the lower or outlet valve opens. It should be gently

page_text: opened, the water will then flow out easily either directly below through a straight
outlet pipe or through a curved pipe so as to flow gently against the side of the
glass. In the older kind of fountain apparatus it has been usual to hold a bottle by
means of a treadle tightly up against a rubber mouth piece on the aerated water
discharge pipe and so fill the bottle under pressure and then empty the bottle into a
glass or eise to hold the glass itself against a rubber disc or plate and fill direct into
the glass. The first plan was circuitous and gave needless trouble and with the glass
there was constant breakage unless a thick and unsightly glass was used.
By my system however the glass measure takes the place of the bottle and the
aerated water is quietly discharged from it as if from an open bottle.
Should however the lifting up arrangement, be really required it can be adapted to
the measuring vessel or be used without it. It may in that case be advisable to adapt
it either for filling a bottle or a glass. This is done by having two rubber discs or
mouthpieces the smaller or bottle mouthpiece centred within the larger or tumbler
mouthpiece or the disc of rubber may be suitably shaped and then be in one piece.
The carrying block or plate is also similarly adapted to hold either the curved or
pointed end of a bottle or the flat bottom of a glass. In any case I prefer to save
cutting the counter in order to fit up a treadle lifting arrangement by having one to
work by hand. To effect this I cause the bottle or glass support to work up and
down between two side pieces or pillars and the under portion of the support is of
metal and cut away diagonally or tapered, so that should a wedge be pushed under it
it will regularly rise and fall as the wedge is introduced or withdrawn. I then have
a semi-circular disc and of its plane at a fixed distance from its outer circumference I
cut away a portion so as to make it gradually taper from almost nothing to its full
thickness. This disc or plate I pivot in such a manner that as I turn it by means of
the handle attached the thin end of the wedge-like circumference introduces itself
under the bottle or glass support and gradually lifts it.
When this hand lifting arrangement is used I generally attach to it a wirework or
plate glass guard which revolves with it and secures the operator from harm should
the glass or bottle burst. I make the handle or lever which draws forward the wedge
plate to operate to some extent separately from the plate itself. Thus when it has
drawn the plate forward by a horizontal movememt I give the handle a vertical or
downward movement by pressing upon it. The lever being pivotted its far end rises,
strikes the lower part of the rack already mentioned, operates the registering
apparatus and by means of the toothed dise and its cams opens and closes the
aerated water valves. When the glass measuring vessel is dispensed with I let the
water outlet on the pillar terminate in a rubber mouth piece for the bottle neck and
(or) the glass but instead of and sometimes in addition to a simple cock as now used
I have a valve which on being pressed down lets the water into the glass &c. Alter-
natively I have a valve box with two valves one for letting the water into the glass
and one for snifting. The handle is pivotted between the valves and has a spur or
continuation to operate the back valve. Then by pressing on the handle the aerated
water is let in and by slightly lifting the handle the glass is snifted. In the case of
the water being let into the glass direct it is best to cause the revolution of the wedge
plate to inove the rack and register on the dial. This can be done by weighting the
rack and fixing a roller to its lower end and by so lengthening and shaping the far
side of the wedge plate that it forms an inclined plane up which the roller travels and
so lifts the rack.
I sometimes use on the pipe bringing the aerated water from the cylinder to the
counter pillar a pressure regulator. I prefer to fix this on or alongside the pillar
itself and to use a pressure guage in connection with it so that the operator can see
the pressure at which he is filling the glasses or the glass measure &c. Its chief
advantage is this that the aerated water in the cylinder is madė at about 120 lbs.
pressure but it is quite sufficient I think if it is sold at 40 lbs. pressure. There is
therefore a great economy of gas in reducing the pressure of the gas and water from
the higher to the lower pressure..
The action of the regulator which I employ for this purpose depends upon the play

page_text: of a valve (which may be either a flat valve with rubber washer or a conical valve)
which opens and closes communication between the gas inlet and the regulator
chamber according to whether the power of a certain spring exceeds or not the
pressure of the gas in the chamber on an elastic diaphragm made of rubber or
leather.
By screwing up or down a nut the spring is tightened more or less and the pressure
desired in the chamber can thus be altered at will. This pressure is independent of
the tension of the gas on its arrival, because it acts equally and in the inverse
direction on the valve and on the elastic diaphragm which rests on a seat of exactly
the same diameter as that of the valve.
On the horizontal pipe leading from the regulator chamber I affix a pipe leading
upwards at right angles and carrying a pressure guage or indicator.
The general form of the pressure regulator is that of an upright hollow cylinder
with rounded ends. Passing down the centre of the cylinder is the vertical valve
spindle. Horizontally dividing the cylinder at about its centre is the diaphragm of
leather or rubber which is securely held all round where it reaches to the sides of the
cylinder and is also tightly held between two nuts where the valve spindle passes
through it. Above the diaphragm the valve spindle carries a spiral spring and round
the upper part of the spindle, turning freely on it and travelling through a threaded
bush is a screwed flynut which by being turned so as to travel downwards upon the
spindle and so compress the spring causes the spindle to slightly descend or puts a
tension on the valve spindle and the diaphragm. At the lower end of the cylinder is
an opening for the spindle to pass through and at the lower or under side of this
opening is the valve seating. At this point the spindle is enlarged to form the valve
head which is thus inside a lower valve chamber and forms a tight joint or seating on
the under side of the outlet from the cylinder that is on the upper or top side of the
valve chamber.
Right across the valve chamber is another horizontal diaphragmn of rubber or
leather which is firmly held in position by means of a packing gland underneath. The
valve spindle has been continued downwards and it also passes through this diaphragm
and by means of nuts a gastight joint is made. There is also at the lower part of the
valve chamber a guide for the end of the valve spindle. The aerated water comes
from the cylinder and enters the valve box and only when the nett tension of the
spring (that is the full tension of the spring less the tension of the gas upon the
diaphragm in the upper chamber of the regulator) permits it, the aerated water can
flow through into the upper chamber and away at a side exit to the outlet tap.
All the foregoing improvements I combine together or use separately as I may
find most suitable and convenient.

Improvements in Machinery and Appliances for or connected with
the Dispensing of Aerated Water.
I JOHN PERKINS JACKSON of 63 Duke Street Liverpool Engineer do hereby
declare the nature of this Invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
My Invention has for its object to provide improved apparatus for the dispensing
of aerated liquors.
The apparatus for the manufacture and storing of aerated liquor may consist of a
high pressure gas generator of usual construction, and of a cylindrical vessel or
reservoir closed at the ends and made of any suitable material such as copper well
tinned internally and provided with openings for the introduction of water and gas
and for the withdrawal of the aërated water. A tube on the gasogene or syphon

page_text: principle may also be provided so that the aërated liquor may be drawn off from near
the bottom of this cylinder or vessel. The cylinder may be stationary and provided
in the interior with an agitator or it may be mounted on pivots in a suitable frame so
as to be capable of being rocked freely to effect the incorporation of the gas and
liquor one or more stationary grids or perforated screens being fitted inside the
vessel to effect the more thorough mixing of the particles of
and liquid.
gas
In the gas generator I place materials for generating carbonic acid gas sufficient
to produce a pressure of, say 120 lbs. on the square inch which will be indicated on a
pressure guage which may be situated on the generator itself or on the cylinder or
on a pipe leading therefrom to the fountain or dispensing apparatus. Gas from the
generator is admitted into the cylinder, until the water contained therein is sufficiently
charged, the said vessel receiving a rocking motion or the water being stirred or
agitated during the admission of the gas, so as to cause the gas to be absorbed by the
water, more gas being admitted as required until the pressure in the vessel stands at
about 120 lbs. In the case of employing liquified carbonic acid gas I admit the
liquid gas into the cylinder until the required pressure is obtained.
When the water is sufficiently charged with gas the supply is cut off and the
cylinder is disconnected and may be coupled up to the pipe leading to the dispensing
fountain, on which pipe there is provided a reducing or pressure regulating valve for
regulating the pressure of the liquor entering the fountain.
My improved fountain or apparatus for dispensing the aërated liquor is illustrated
by Figures 1 and 2 of the accompanying drawings. Figure 1 being a side elevation
partly in section and Figure 2 a front elevation; the remaining figures are details
hereinafter referred to. A is a standard or pillar which may be fixed to a counter or
other suitable support. Attached to or forming part of this standard or pillar is a
bracket B preferably of metal constituting a table or support for a vessel C which
consists of a cylinder (preferably of glass). The lower end of this cylinder is placed
in a recess in the bracket or table B and the upper end is closed by a disc D the whole
being securely held together either by stays or supports on the exterior or as shewn in
the drawing, by means of a bolt E passed through a hole in the cover D and screwing
into the bracket B which constitutes the bottom of the vessel.
Packing E of india rubber or other suitable material is interposed between the
ends of the cylinder C and the bracket B and the cover D to ensure fluid tight joints
at these parts.
In the cover D is an opening by which aërated liquor enters the vessel C, the said
opening communicating by a pipe or tube F with the liquor container or reservoir
the bottom B of the vessel also having an outlet G for the aörated liquor from the
vessel B the said outlet being provided with a tube H for conducting the liquor into
a tumbler or other receptacle. The pipes or tubes F and H are each provided with a
valve for governing the passage of the liquid into and from the vessel C which valves
are maintained in their normal closed position by springs as shewn in Figure 3 which
illustrates in section and end views one of the valves detached.
The vessel C is provided (preferably on the top plate or cover D) with a snifting
valve" I maintained on its seat by a spring K. The spindle L of this valve extends
upwards and is provided on its upper end with a knob or handle N by means of which
the valve may be opened when required to allow the air confined inside the vessel to
pass out, the lower part of the valve spindle being made hollow or provided with a
groove or grooves in it for that purpose.
The spindle L also extends below the valve I and when depressed forces from its
seat a buoyant valve 0 coutained in a cage P attached to the interior of the
cover D. This valve as the liquid rises in the chamber C rises with it and, when
the chamber is fully charged with liquid, closes the passage to the valve I and
so prevents the liquid escaping therethrough even if the snift valve is being held
open. By depressing the valve spindle this lower valve O may be forced off its
seating so as to open the communication between the interior of the vessel and the
outer air.

page_text: .
The inlet valve Q and the outlet valve R for controlling the passage of the
aërated liquid to and from the vessel C are opened and closed alternately which
may most conveniently be done in the following manner-Fitted to turn in
bearings S in brackets projecting from the standard A is a shaft or spindle T
provided on one end with a handle U and having fast thereon a segment V. On
one face of this segment are fitted or formed cam surfaces W and X which by
partially rotating the spindle T are caused to bear respectively upon the
spindles Y Z of the valves Q and R so as to open the said valve at the required
periods to fill the vessel C with liquid and discharge the same from the said vessel.
To charge the vessel C with the aërated liquid from the cylinder or reservoir the
handle U is pulled forward in the direction of the arrow in Figure 1 thereby
turning the segment V so as to cause the cam surface W to come into contact
with and depress the spindle Y of the inlet valve Q and thus open the said valve
and admit aërated liquid into the vessel C. As the liquor is entering the vessel
and when the said vessel is about half full the valve I may be depressed so as to
allow some of the confined gas and air to escape by the passage or passages z in
the valve seat whereby the pressure inside the vessel is reduced and more liquid
is able to flow in. When the vessel is fully charged with the liquid the buoyant
valve O will close the passage y and prevent the escape of the liquor therethrough
even if the snift valve is being held down.
To discharge the liquor from the vessel C the handle U is pushed back in the
reverse direction to that indicated by the arrow so as to remove the cam surface W
out of contact with the spindle Y whereupon the valve Q will close under the
action of its spring a Figure 3. The snift valve is now depressed and the whole
of the pressure blown off then by a further motion of the handle U in the same
direction the cam surface X is brought into contact with and caused to depress
the spindle Z of the outlet valve R thereby opening the said valve and allowing
the liquor by its own weight to flow out of the vessel through the pipe or tube H
into a tumbler 6 or other receptacle placed in position to receive it.
If only a
portion of the liquor is required to be withdrawn from the vessel C; when the.
required quantity of liquor is withdrawn the handle U may be moved in the
direction of the arrow so as to remove the cam surface X from the spindle Z,
the remaining portion being discharged when required by again moving the handle
so as to cause the cam X to again open the valve R.
When the contents of the vessel have been discharged the handle U is returned to
its normal position shewn in Figure 1 in readiness for the next operation the ends
of the spindles being then opposite the plain or lower surfaces c and d of the
segment V.
In order to prevent fraud and to register the number of times the vessel C has
been discharged there is provided on the bracket A. a counter or registering,
apparatus e which may be operated by any convenient means from a moveable part
of the apparatus so as to indicate on the registering device each charging or dis-
charging operation of the apparatus.
A convenient arrangement for operating the registering mechanism is illustrated in
the drawings and consists in providing on the shaft or spindle T or on the segment V
a projection or tail piece of which when the segment V is moved into position to open
the valve Q comes into contact with the lower end of a rod or bar g and raises the
said bar in its bearings or supports h. The upper end of the bar g is provided with
pins or studs i engaging an arm or projection j from a pawl which actuates a ratchet
wheel connected with the first gear wheel which effects the rotation of the numbered
wheels of the counter so that at each elevation of the bar by the tail on the
segment V the indicating wheels of the counter are moved one number forward
thereby indicating the number of times the vessel C has been filled so that if the said
vessel be of a certain known capacity the quantity of liquor discharged from or passed
.through the vessel may be readily ascertained.
To prevent the mechanism being tampered with so as to extract liquor without

page_text: operating the registering mechanismn the operating parts may be enclosed and
locked in a glass or other suitable case the key thereof being retained by the
proprietor.
The outlet valve R should be gradually opened so that the liquor will flow out
through the pipe H gently against the side of the glass. In fountain apparatus
hitherto in use it has been usual to hold a bottle by means of a treadle tightly up
against a rubber mouthpiece on the aërated liquor discharge pipe and so fill the bottle
under pressure and then to empty the bottle into a glass or else to hold the glass itself
against a rubber disc or plate and discharge the aërated liquor into the glass direct.
The first plan is troublesome and in the latter case the glasses were frequently. broken
unless a thick and unsightly glass was used. By my system the vessel C takes the
place of the bottle and the aërated liquor is quietly discharged from it into the glass
as if from an open bottle.
Should however the lifting up arrangement be required it can be adapted for use
with the measuring vessel C or be used without it. To render it applicable for being
used for filling either a bottle or a glass two rubber discs or mouthpieces may be
provided one smaller than the other, the smaller one being suitable for bottles and
centred within the larger disc which should be of suitable size to fit the mouth of a
tumbler. The block or plate for carrying the bottle or glass should be suitably shaped
to hold either the curved or pointed end of a bottle or the flat bottom of a glass.
I prefer to work the lifting arrangement by hand in order to save cutting away the
counter to work it by means of a treadle.
For this purpose the support may be fitted to slide up and down between two side
pieces or pillars and be raised into position by means of a wedge or wedges
interposed between the support and the surface of the counter or table on which it is
fitted.
A curved or circular and pivoted wedge shaped disc turned by a handle is
preferably used for raising the support and in combination with this rotating
wedge a wirework
or plate glass guard may be made to revolve with it into
position to protect the operator from injury should the glass or bottle burst while
being filled.
The handle by which the wedge is rotated may impart motion to the registering
apparatus such as hereinbefore described to indicate each filling operation. If desired
the measuring vessel C may be dispensed with in which case the tube or pipe leading
from the reservoir terminates in a rubber mouthpiece for the bottle neck and for the
glass but instead of or in addition to the simple cock as now often used I provide a
valve which on being pressed down admits the liquid into the glass or the like. Or a
valve box may be provided having two valves, one for governing the passage of the
liquor into the glass or the like and the other for "snifting." Between these valves a
handle is provided by moving which in one direction the valve for admitting liquor to
the bottle or the like is opened and by moving it in the other direction the snifting
valve is opened. In the case of the liquor being let into the glass direct, the
revolution of the wedge plate for raising the glass may be made to operate the
registering mechanism by providing an inclined plane on the wedge disc to bear upon
a roller in the bar which operates the registering mechanism so as to lift the bar at
each operation.
On the pipe which conducts the aërated liquor from the cylinder or reservoir to the
fountain there is fitted a pressure regulator or reducing valve which I prefer to fix on
or alongside of the standard A and to use a pressure gauge in connection with it as
shewn in Figure 4 so that the operator can see the pressure at which he is filling the
vessel C or dispensing the liquid.
The chief advantage of this regulator is that while the aërated liquor in the
generator or reservoir is at about 120 lbs. pressure about 40 lbs. pressure is sufficient
for it to be sold at and therefore a great economy of gas is obtained by reducing the
pressure of the liquor from the higher to the lower pressure.
The reducing apparatus which I prefer to employ is shewn in vertical section in

page_text: Figure 4 and consists of a valve k operated by the pressure of the aërated liquor so as
to open and close more or less a communication between the inlet passage m from
the reservoir and the outlet o leading to the vessel C or to a bottling apparatus. On
the spindle of the valve are secured two diaphragms q q² one of which (q) divides the
pressure regulator into two compartments 2, 3 it being securely held all around its
edge at the junction t where the two parts constituting these two compartments are
screwed together. Above the diaphragm the valve spindle is surrounded by
the spiral spring p the upper end of which spindle turns freely in a recess in a
screwed nut by means of which nut the power of the spring may be regulated as
required.
At the lower part of the compartment 3 below the diaphragm 9 is the opening
through which the valve spindle passes and at the lower or under side of this opening
is the seating for the valve k.
This valve is sisuated inside a lower chamber u which communicates by the pipe m
with the cylinder or liquor reservoir. At the lower part of this valve chamber u is
secured by a cap or plug 4 and the nuts 5 on the lower end of the valve spindle the
lower diaphragm q².
The aërated liquor from the cylinder or reservoir enters the regulator by the pipe m
and only when the nett tension of the spring p (which is the full tension of the spring
less the tension of the gas upon the diaphragm q) permits it, can the aërated liquor
flow through the passage into the compartment 3 and out therefrom by the exit o to
the vessel C or to a bottling apparatus.
Should the pressure in the pipe m and chamber u increase so as to exceed the
pressure for which the spring had been adjusted to resist and therefore tend to force
the valve onto its seat and thus close the passage the said excess of pressure
by acting on the lower diaphragm q" will counteract this tendency and maintain the
valve k open.
On the pipe leading from the regulator chamber 3 to, the vessel c is affixed a pipe s
leading to the pressure gauge or indicator w which will indicate the pressure of the
liquor entering the vessel C.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. In a fountain or apparatus for dispensing or delivering aërated waters or
liquors the combination with a cylinder or reservoir of aërated water of a receiving or
measuring vessel and a valve or valves actuated substantially as described for admitting
the desired quantity of aërated water or liquid from the cylinder or reservoir into
the receiving or measuring vessel and then for discharging the water or liquor
from the said vessel substantially as herein before described with reference to the
accompanying drawings and whether the counter or registering device be used
therewith or not.
Second. The combination with a fountain or apparatus for dispensing or delivering
aërated waters or liquors of a vessel communicating with the aërated liquor cylinder
or reservoir by a pipe or passage provided with a pressure regulator or reducing
valve and with or without a pressure gauge or indicator substantially as and for the
purpose herein before described.
Third. In combination with apparatus for dispensing aërated liquor a pressure
regulator with a lower compensating diaphragm substantially as hereinbefore described
with reference to Figure 4 of the accompanying drawings.
Fourth. In an apparatus for dispensing or drawing off aërated liquor the combina-
tion of a measuring vessel and a registering apparatus whereby the quantity of
aërated liquor drawn off can be measured and recorded.
Fifth. The general combination and arrangement of parts constituting an improved
fountain or apparatus for dispensing or delivering aërated liquor substantially as
herein before described and illustrated by the accompanying drawings.

page_text: Sixth. In an apparatus for dispensing or drawing off aerated liquor, the use of an
intermediate or measuring vessel, fitted with a snift valve, whereby the aerated liquor
is collected in the intermediate vessel at a regulated high pressure, which can then be
blown off and the liquor flow out by its own weight.
