PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Supplying Aerated Liquids from
Bulk on Draught.
We, FRANK BRACEBRIDGE MILLS, Engineer, of 50, St. George's Avenue, Tufnel
Park, in the County of London, and HENRY JOHN ETHERINGTON, of 58, Old
Broad Street, in the City and County of London, do hereby declare the nature
of this invention to be as follows:-
This invention for improvements in apparatus for supplying aerated liquids
from bulk on draught relates to apparatus in which the aerated liquid is stored
in a reservoir at a high pressure and from which reservoir any desired quantity
can be drawn off into a measuring vessel, and when the measuring vessel is shut
off from the reservoir its contents can be discharged; and has for its object to
render the valve controlling the drawing of the liquid into and the discharge
from the measuring vessel gas tight, and to improve the construction of the
measuring vessel.
In carrying out this invention, the pressure of the liquid on the controlling
valve forces the valve on to its seat, and the valve rod is so connected to the
operating handle that it can only be rotated by it. The liquid is conveyed
through a passage from the reservoir outside the valve seating to the valve
chamber and so forces the valve on to its seating. The valve and seating have
the necessary ports and passages to control the drawing and discharging of
the liquid.
The valve is also pressed on to its seat by a helical spring that bears on a
central loose washer, and is rotated on its seat by tongues or projections con-
nected to an operating handle and taking into notches or' recesses in the
valve.
The measuring vessel consists of an open ended glass cylinder that is held
within and between the ends of an open metal cage which is connected to the
apparatus and carries the discharge spout.

page_text: Broad Street, in the City and County of London, 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:--
This invention for improvements in apparatus for supplying aerated liquids
from bulk on draught relates to apparatus in which the aerated liquid is stored
in a reservoir at a high pressure and from which reservoir any desired quantity
can be drawn off into a measuring vessel, and when the measuring vessel is shut
off from the reservoir its contents can be discharged; and has for its object to
render the valve controlling the drawing of the liquid into and the discharge
from the measuring vessel gas tight, and to improve the construction of the
measuring vessel.
In carrying out this invention, the pressure of the liquid on the controlling
valve forces the valve on to its seat, and the valve rod is so connected to the
operating handle that it can only be rotated by it. The liquid is conveyed
through a passage from the reservoir outside the valve seating to the valve
chamber and so forces the valve on to its seating. The valve and seating have
the necessary ports and passages to control the drawing and discharging of
the liquid.
The valve is also pressed on to its seat by a helical spring that bears on a
central loose washer, and is rotated on its seat by tongues or projections con-
nected to an operating handle and taking into notches or recesses in the
valve.
The measuring vessel consists of an open ended glass cylinder that is held
within and between the ends of an open metal cage which is connected to the
apparatus and carries the discharge spout.
In the accompanying drawings:
Fig. 1 is a vertical section of the apparatus constructed according to this
invention.
Fig. 2 is a vertical section taken at right angles to Fig. 1.
Fig. is a cross section of the valve body on the line A-A Fig. 2 showing
the valve resting on its seat.
Fig. 4 is a similar cross section with the valve removed.
Figs. 5 and 6 are plan and inverted plan respectively of the valve.
A standard a (supported by a base not shown) supports the valve body e and
measuring vessel and encloses a pipe communicating with the valve
chamber and with a reservoir containing aerated liquid at a high pressure.
The face valve within the valve chamber c', controls the passage of the
aerated liquid to the measuring vessel d and also the escape of the gas there-
from. The said valve rests on a seating and is rotated by the horns which
project from the spindle e carrying the operating handle and engage freely
in notches in the valve. The valve is held down upon its seating and
the valve spindle up against its seating e3 by the compression spring e and
by the pressure in the liquid.
Connected to the valve body and centrally under the valve seating is a tube f
in which works a hollow piston and piston rod f¹ supported in their normal
raised position by the spring and through which passes the spindle f³
provided at its top end with a valve fadapted to open and close the annular
passage through the piston rod and at its lower end with a plug or stopper f³
adapted to close the spout orifice das is shown in Fig. 2.
The measuring vessel d comprises an open ended glass cylinder № held
between the ends of the metal cage d³.
In Fig. 1 the various parts are shown in their normal positions, the inter-
mediate reservoir being opened to the atmosphere at the spout and through
the hole in the valve seat, the recess in the face of the valve and the
hole in the valve seat communicating with the space in the column a surround-
ing the supply pipe b: the inlet being opposite a solid portion of the valve
seating so that the high pressure liquid in the chamber c¹ is cut off from the

page_text: central chamber and thus from the measuring vessel a.
is shown in the same position as in Fig. 1.
In Fig. 3 the valve
Upon turning the handle e and with it the valve through 90 degrees to the
position shown in Fig. 2 the recess in the valve is removed from the holes c
and and the inlet is brought over the recess c¹0 in the valve seat com-
municating to the central chamber . The high pressure liquid entering the
chamber drives down the piston f¹ and with it the valve spindle f³ until
the plug f meets the bottom of the vessel d when by the continued downward
movement of the piston f¹ the valve f* is caused to leave its seating and to allow
the liquid to pass through the hollow piston rod and enter the measuring
vessel through the orifices f6 in the piston rod. The liquid continues rising
in the vessel until the pressure of the gas confined above its surface is equal
to the pressure with which the liquid is entering, after which no further movement
of the liquid occurs. On returning the valve to the position shown in Fig. 1
the confined gas is allowed to escape through the hole c, recess and hole c
into the column a when the piston f immediately returns to its normal position,
opening the spout orifice and thus allowing the liquid to discharge itself
freely and without shock into a glass or other receptacle held to receive it.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. In apparatus for supplying aerated liquids from bulk on draught, the com-
bination with a reservoir for containing aerated liquid under pressure of a rotat-
able controlling valve forced on to its seat by the pressure of the aerated liquid,
a measuring vessel into which the liquid is forced from the containing reservoir
and means for automatically closing the outlet of the measuring vessel when it is
in communication with the containing vessel and opening it for the egress of
the liquid when the vessel is closed to the containing vessel and open to the
atmosphere, substantially as described.
2. In apparatus for supplying aerated liquids from bulk on draught, the com-
bination of a rotatable controlling valve forced on to its seating by the pressure
of the aerated liquid, a spindle carrying an operating handle and having pro-
jecting horns or tongues engaging in notches in the valve, and a spring forcing
the valve and the spindle on their seatings in the valve chamber, substantially
as described.
3. Apparatus for supplying aerated liquids from bulk on draught the whole
arranged constructed and operating substantially as hereinbefore described and
illustrated in the drawings hereunto annexed.
