PROVISIONAL SPECIFICATION.
Improvements in Stoppers for Bottles for Containing Aĕrated or
Gaseous Liquids.
I HENRY BARRETT, of No. 268, South Lambeth Road, in the county of Surrey,
Manufacturer, do hereby declare the nature of this invention to be as follows :-
This invention relates to providing screw stoppers and internal stoppers, when such
stoppers are used for closing bottles containing aërated or gaseous liquids, with a hole
passing through the centre, or from the head of the stopper to below the seating of
the said stopper. The said hole at the top or head of the stopper is screw threaded to
receive a screw plug or small screw stopper, which is fitted with a ring or washer
under the head, or at such other part of the stem as is best suited for the purpose; or
instead of screw threading the hole in the stopper, the plug may be provided with a
nut this latter arrangement is advantageous when the stopper is placed in the bottle
before the bottle is completed, and in this case I find porcelain is a suitable material
for the stopper as it is not likely to fly from the effect of the heat required to complete
the manufacture of the bottle.

Gaseous Liquids.
I, HENRY BARRETT, of No. 268, South Lambeth Road, in the county of Surrey,
Manufacturer, 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 :-
The invention relates to providing screw stoppers and internal stoppers, when such
stoppers are used for closing bottles containing aërated or gaseous liquids, with a hole
passing through the centre, or from the head of the stopper to below the scating of
the said stopper. The said hole at the top or head of the stopper is screw threaded to
receive a screw plug or small screw stopper, which is fitted with a ring or washer
under the head, or at such other part of the stem as is best suited for the purpose; or
instead of screw threading the hole in the stopper, the plug may be provided with a
nut this latter arrangement is advantageous when the stopper is placed in the bottle
before the bottle is completed and in this case I find porcelain is a suitable material
for the stopper as it is not likely to fly from the effect of the heat required to complete
the manufacture of the bottle.
In order to enable my invention to be fully understood I will proceed to describe
how it can be carried into practical effect by reference to the accompanying drawing
in which figure 1 is a vertical section and figure 2 a plan of a screw stopper con-
structed according to my invention for use with bottles containing aërated or gaseous
liquids, the plug with which I provide the stopper being screwed into the head of the
stopper; figures 3 and 4 are a vertical section and a plan respectively of a conical
internal stopper and figure 5 is a vertical section of a spherical stopper having plugs
screwed therein according to my invention: figures 6 and 7 are similar views to
figures 1 and 2 but showing a screw stopper having a plug provided with a screw
nut, figure 8 is a section illustrating the application of this kind of my plug and
nut to an internal stopper. Similar letters in all the figures represent similar or corre-
sponding parts.
Referring to figures 1 and 2 a, represents the screw stopper and b, c, the hole
which I form through the centre thereof the upper part c, of the said hole being
larger than the lower part b, and screw threaded as shewn in figure 1 to receive the
screw plug or small screw stopper de, is the ring or washer which I have here
shewn placed under the head of the screw plug d, but the washer can if required
obviously be situated at the bottom of the screw plug f, is the usual washer below
the shoulder of the screw stopper a, for forming the joint with the mouth of the bottle.
It will be seen that if a bottlo for containing aërated or gaseous liquids be provided
with a screw stopper of the herein before described construction the screw plug d, will
by being partially unscrewed serve as a valve for relieving the bottle of internal
pressure prior to removing the screw stopper a, from the mouth of the bottle. Further
when it is required to fill the bottle it can be charged with liquid through the stopper a,

page_text: by partially unscrewing the said plug, the liquid passing through grooves d², d¹, in
the plug
d.
Figures 3 and 4 show a similar screw plug to that hereinbefore described by
reference to figures 1 and 2 applied to an internal stopper a, having the shape of a
double cone and provided with a central hole b, c, the screw plug d, in this case being
of course only required for the purpose of relieving the bottle from the internal
pressure of the gas so as to avoid the accidents which frequently occur when opening
bottles by forcing internal stoppers from their seats, the gas passing out between the
plug & and the stopper a when the plug is partially unscrewed.
Figure 5 shews a spherical internal stopper provided with a similar central
hole b, c, and screw plug d, the head of the latter being elongated so that it shall
project from the mouth of the bottle to allow of its being manipulated. In figures 6
and 7 d, represents the screw plug which is here shewn extending right through the
centre hole in the stopper a, and having a head a', provided with a washer b', on its
lower end; the said hole is of equal diameter throughout its length and is not screw
threaded; 9, is the nut with which I provide the screw plug d, the said nut con-
veniently having projections as shewn to allow of its being easily turned; a radial
groove h, is formed on the underside of the nut communicating with the hole b, and
serving for the passage of the liquid when filling the bottle in which case the nut
must be partially unscrewed. When the bottle has been charged the nut is turned so
as to bring the screw plug or valve to its seat and to give it the required pressure
thereon. To open the bottle the internal pressure can be first relieved by partially
unscrewing the nut g.
Figure 8 shews an internal stopper provided with a similar central hole b, screw
plug d, and nut g, but the nut does not require to be formed with the radial filling
groove hereinbefore described as the bottle is not filled through the stopper.
Although I have illustrated my improved stoppers forined with an axial or central
holo it will be obvious that the hole can extend from any suitable part of the head
of the stopper to a point below the seating of the stopper but I prefer the arrangement
shewn in the drawing.
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 :-
1. Providing screw stoppers and internal stoppers for bottles for containing aërated
or gaseous liquids with a hole passing through them the said hole being closed by a
screw plug or stopper or a screw plug and nut substantially as and for the purposes
herein before described.
2. The improved stoppers for bottles for aërated or gaseous liquids hereinbefore
described and illustrated in the accompanying drawing.
