Improvements in Apparatus for Drawing off or Dispensing Aërated
Liquids.
We ROBERT AUGUSTUS PANCHAUD of 43 Great Tower Street in the City of
London Secretary and WILLIAM GEORGE TEMPLE of 80 Malden Road in the
County of Middlesex Mechanic do hereby declare the nature of this invention to be
as follows:-
This invention relates to apparatus for drawing off or dispensing aërated liquids
in which the aërated liquid is drawn from the main reservoir into an intermediate
vessel from which gas pressure is then relieved and then the contents of the said
intermediate vessel are drawn off at a reduced pressure into a glass or the like for
consumption. The object of this invention is to utilize the pressure in the aërated
liquid itself when first introduced to the intermediate vessel to effect its closure and
then when the communication between the main reservoir and the intermediate
vessel has been closed and the pressure in the said vessel has been reduced by
allowing a portion of the gas to escape, the outlet from the intermediate vessel
automatically opens to discharge the contents thereof. The following is a convenient
arrangement according to this invention I provide in the intermediate vessel a tube
or cylinder in which a piston slides the said piston acting on a valve for closing the
outlet from the intermediate vessel. When the liquid under pressure is admitted
to the said tube or cylinder on its way through a perforation or perforations therein
into the intermediate vessel; as the said perforation or perforations will not allow
the liquid to pass so quickly as it is admitted a pressure is created which acting on
the piston operates the valve to press it onto its seat. The movement of the valve
to open the outlet from the intermediate vessel, when the gas pressure in the said
vessel is relieved, may be effected by a spring.
As in the foregoing arrangement the perforation or perforations which allow the
liquid to pass from the chamber or tube into the intermediate vessel is or are
necessarily small I may in cases where it is desired to provide a larger passage for
the admission of the liquid into the intermediate vessel employ a hollow piston rod
fitted with a valve stem longer than the hollow piston rod and passing through it
and the piston so as to leave a space between, the valve stem at top being provided
with a valve which can seat itself in a seating around an orifice in the piston and
provided at bottom with the valve which closes the outlet from the intermediate
vessel. When the liquid under pressure is admitted into the tube or cylinder the
piston rod and valve stem are depressed in the said tube or cylinder until the bottom
valve presses on its seating and closes the outlet from the intermediate vessel. The
pressure then continues to depress the hollow piston and rod until the lower end of
the said rod reaches the bottom valve and this movement allows liquid to pass
through the orifice which was closed by the upper valve and down through the
hollow piston rod through an orifice or orifices therein into the intermediate vessel.
When the pressure is relieved a spring raises the hollow piston and rod and when
the piston comes in contact with the upper valve it raises the bottom valve from its
seat for the discharge of the liquid.

Improvements in Apparatus for Drawing off or Dispensing Aërated
Liquids.
We ROBERT AUGUSTUS PANCHAUD of 43 Great Tower Street in the City of
London Secretary and WILLIAM GEORGE TEMPLE of 80 Malden Road in the
County of Middlesex Mechanic do hereby declare the nature of our 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 drawing off or dispensing aërated liquids
in which the aërated liquid is drawn from the main reservoir into an intermediate
vessel from which gas pressure is theu relieved and then the contents of the said
intermediate vessel are drawn off at a reduced pressure into a glass or vessel for
consumption. The object of this invention is to utilize the pressure in the aërated
liquid itself when first introduced from the main reservoir to the intermediate vessel
to effect the closure of the said intermediate vessel after which the communication
between the main reservoir and the intermediate vessel is closed and then the
pressure in the said vessel is reduced by allowing a portion of the gas to escape and
then the outlet from the intermediate vessel automatically opens to discharge the
contents thereof.
We will describe with reference to the accompanying drawings what we consider
the best method of carrying this invention into effect premising however that we
do not limit ourselves to the precise details shewn.
Figure 1 is a vertical section (on the line 1, 3 Figure 3) of an apparatus
constructed according to our invention the parts being shewn in the positions
which they occupy when the liquid under pressure is being admitted to the inter-
mediate vessel.
Figure 2 is a vertical section taken along the line 1, 2 in Figure 3 the parts
being shewn in the position they occupy when the intermediate vessel is empty or
being discharged.
Figure 3 is a plan of the valve box the valve being removed so as to shew the
passages in the valve seat, and
Figure 4 is a face view of the valve shewing the ports or passages therein.
A is a pipe communicating with the reservoir (not shown in the drawings) and
opening into the valve box B to which the intermediate vessel C may be attached
by the screw collar and nut by which the flange c' is pressed against the
washer, as shewn or in any other convenient way. The pipe A. communicates
with the passage a in the valve seat D which passage, when the valve E is in the
position shewn in Figure 1, communicates by a radial passage b in the valve E with
a passage c in the valve seat and leading to the interior of the vessel C. Connected
to the underside of the valve seat and communicating with the passage c is a
tube or cylinder containing a piston d provided with a hollow piston rod G
through which and through the piston passes a rod or stem e which passes loosely
through the passage in the said piston and piston rod, a space being left between
the stem e and the interior of the hollow rod G and piston d for the passage of
liquid as hereinafter described. The stem e is provided at its upper end with a
valve which normally closes the passage through the piston and piston rod and
carries at its lower end a plug or stopper g for closing the outlet from the vessel C.
When the vessel C is empty and the valve E is in the position shewn in
Figure 2 liquid cannot enter the said vessel C and the piston d and valve fare
maintained by the spring b at the upper end of the cylinder F as shewn in Figure 2
the valve being closed upon its seat in the said piston d. When the valve E is
in this position the interior of the vessel C is in communication with the external
atmosphere by passages in the valve seat D connected together by the passage k
in the valve E, the passage i leading to the interior of the vessel and the passage

page_text: being open to the atmosphere. The spindle E' of the valve E is provided with a
handle Es by which the valve may be turned in the direction and to the extent
required. When the handle E³ is turned into the position shewn in Figure 1 the
liquid under pressure will pass from the reservoir through the pipe A and
passages a b and c into the cylinder F and the pressure thereof by acting on the
piston d and its valve will cause them to descend thereby compressing the spring
and forcing the plug or stopper into the discharge opening h of the vessel C.
The presser still acting on the piston d causes it to descend still further it then.
sliding independently of the stem e away from the valve thereby opening the
passage in the piston d and piston rod G through which passage the liquid will pass.
and through openings in the lower end of the piston rod into the vessel C until.
the vessel is filled or has received its required supply. To deliver the liquid from
the vessel C for consumption a glass or other suitable receptacle is placed
beneath the discharge opening and the valve E is turned by means of the handle E
into the position shewn in Figure 2 so as to cause the passage k in the valve to.
connect the passage i, and the passage a to be closed by a solid portion of the
valve so that the communication between the reservoir and vessel C is cut off' and
gas pressure above the liquid in the vessel C is allowed to escape into the
atmosphere through the passages i. and 2. The pressure in the vessel being thus
reduced the piston d under the action of the spring rises in the cylinder F and
coming into contact with the valve lifts the rode and raises the plugg out of the
discharge opening h. The liquid will then flow from the vessel C at the required
reduced pressure (into the receptacle placed in position to receive it) in a sparkling
and fresh condition and without undue splashing. In the upper end of the
cylinder F or in the nozzle by which it is connected to the valve seat D is a small
opening through which the liquid contained in the cylinder Fabove the
piston d passes into the vessel C as the piston rises in the cylinder. The
apparatus may be fixed, to a counter or other suitable support and the pipe
leading to the reservoir may be enclosed in a tubular bracket H as shown or be
otherwise concealed.
The foregoing arrangement provides a large passage for the liquid to the
intermediate vessel after the valve g is closed. The arrangement can be simplified
without however the advantage of the said large passage, if the piston be made
solid and its rod be provided with the valve a hole as at n affording a
passage for the liquid under pressure from the cylinder F to the vessel C the
said hole being sufficiently large for the purpose but not so large as the inlet
passage a b c so that the liquid is admitted to the cylinder F at a greater rate than
that at which it passes therefrom by the hole n and therefore the requisite pressure
is obtained to close the valve g.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In apparatus for drawing off or dispensing aerated liquids means whereby the
pressure in the aerated liquid is utilized to effect the closure of the outlet from an
intermediate vessel into which the liquid is admitted from the reservoir before being
delivered for consumption substantially as herein before described.
2. In apparatus for drawing off or dispensing aerated liquids, means whereby the
pressure in the aerated liquid is utilized to effect the closure of the outlet from an

the reservoir and the intermediate vessel is closed and after a portion of the confined
gas is allowed to escape and the pressure in the said vessel has thereby become
reduced the outlet from the said vessel automatically opens to discharge its contents
substantially as hereinbefore described.
