THOMAS HENRY WALKER, of 14 Boden Street, Nottingham, Lace Maker,
and GEORGE SOAR, Clydemont, Lucknow Road, Nottingham, Lace Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention is for a bottle and valve for holding and liberating soda water
and other gaseous mineral waters, which bottle through the action of the valve
will not burst when opened, therefore avoiding breakages and consequent injury
to the person using the same.
The invention consists of a valve applied to bottles of the ordinary shape for
mineral waters except that on one side of the neck of the bottle a small recessed
hole is made. The valve is made of metal or other material and consists of a
spindle with a coarse screwthread, a nut with a milled edge; or at option, a wing
nut, screwed to suit the thread of the spindle, also at option a spiral spring between
the milled or wing nut, a small head at the outer end of the spindle to prevent
withdrawal and loss of the milled or wing nut, a flat head slightly larger in
diameter than the hole in the bottle neck on the inner end of the spindle and a
small rubber ring or washer to fit on the spindle and up to the hole in the bottle
neck on the inside. The valve is fitted into the hole in the bottle neck and when
the bottle is full of mineral water the rubber washer or ring is forced against the
hole by the pressure of gas in the bottle. To prevent any possible leakage of
the contents of the bottle the valve is drawn up tight on the inside of the bottle
by the milled or wing nut on the outside being screwed down to it.
To open the bottle it is simply necessary to release the milled or wing nut by
unscrewing with the fingers and press on the end of the spindle. This forces
the valve open and allows the confined gas to escape, when the glass ball stopper
will fall.
The bottles may be re-charged time after time, but the milled or wing nut as
before mentioned should be screwed down to keep the contents of the bottle fresh
and to prevent gas escaping.
What we claim is that by the use of these valves and bottles, bottles containing
gaseous liquids such as soda water and the like are opened easier, and there is
less chance of bursting bottles and consequent injury to the person opening the,
bottle.

We, THOMAS HENRY WALKER, of 14 Boden Street, Lace Maker, and GEORGE
SOAR, of Clydemont, Lucknow Road, Lace Manufacturer, both in the Borough
of Nottingham, do hereby declare the nature of this invention and in what manner
Price 8d 1

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates more particularly to internally-stoppered bottles for hold.
ing aerated liquids, and it has for its object to provide improved means for relieving
the internal pressure, so that the internal stopper will fall from its seat, and the
bottle may be thus opened with ease without an instrument, and without risk
of bursting the bottle."
The invention will be best understood by reference to the accompanying
drawings in which
Fig. 1. is a side elevation, and
Fig. 2. a vertical section, showing our invention applied to an ordinary interior
stoppered glass bottle, part only of the latter being shown.
Fig. 3. is a view of a portion of the exterior of the bottle showing the opening in
the wall;
Figs. 4 and 5 are side and front views respectively of the external washer, and
Figs. 6 and 7 are respectively side and end views of the valve.
Like letters indicate like parts throughout the drawings.
According to our invention the bottle A is formed with a gas outlet at a point B
in the neck, which is preferably above the level of the liquid. This outlet is
normally closed by a valve which comprises a spindle provided at its inner end
with a head C and an india-rubber washer D which is placed between the head C'
and the interior surface or scat A¹ on the bottle.
The outer end of the valve spindle C is formed with a screw thread, and on this
part is a metal washer E. and a preferably winged or milled nut F. provided on
its inner side with an extension or sleeve F.
On the sleeve F between the washer E and nut F is a helical spring G, which
holds the washer D up to the seat A on the bottle, and thus closes the outlet.
The internal pressure also tends to hold the valve on the seat.
By a slight pressure on the outer end of the valve spindle C however the valve
is moved from the seat, and the outlet opened and the gas thus allowed to escape.
In order to prevent the outlet from being accidentally opened, and also to hold
and lock the valve more securely on the seat and thus prevent any possibility of
the escape of gas in transit, the nut F can be screwed up and the end of the
extension or sleeve F1 engages with the metal washer E so that the valve is firmly
held on its seat.
To prevent the valve spindle C from rotating when the nut F is turned it is
formed with one or more flat parts and the metal washer E (see Fig. 4.) with a
hole shaped to correspond as shown. The washer E is formed with extensions E¹
which engage with the sides of the recess A³ in the exterior of the bottle, this
recess is approximately elliptical in shape and the washer is thus itself prevented
from turning round.
In order that the valve spindle C and nut F may not project above the external
surface of the bottle the recess A2 is made of sufficient depth as shown to receive
the nut F.
Radial grooves J (see Fig. 3.) may be also formed in the bottom of the recess
to allow the gas to escape past the washer E.
To open the bottle the nut F is released, the valve is then pushed in with the
thumb or a finger, and held in this position until all the gas has escaped and
the stopper K falls from its seat.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, we declare that what we
claim is:-
1. The combination with an internally stoppered bottle provided with a gas
outlet of a valve for closing the gas outlet and external means for holding the
valve firmly against its seat substantially as described.

page_text: 2. The combination with an internally stoppered bottle provided with a gas
outlet of a valve such as C C D for closing the outlet and a nut such as F on the
valve spindle for holding the valve firmly against its seat substantially as described.
3. The combination with an internally stoppered bottle provided with a gas
outlet of a valve such as C C D nut F and spring G substantially as and for the
purpose described.
4. The combination with an internally stoppered bottle provided with a gas
outlet of a valve such as C C D washer E, grooves J, spring G and nut F,
substantially as and for the purpose described.
5. The combination and arrangement of parts constituting the complete bottle
substantially as described and illustrated in the accompanying drawings.
