I HENRY BARRETT of 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 improvements in valve screw stoppers for bottles for
containing aërated or gaseous liquids.
In the manufacture of such stoppers according to the present invention I mould or
otherwise make a hollow screw stopper that is to say, a screw stopper with a hole
passing right through it, the said hole being adapted to receive a valve through which
I charge or fill the bottle with liquid. The valve consists of a. stem fitted with a
rubber or cork washer; the object of the washer is to make a joint against the bottom
of the stopper or the upper part thereof as the case may be by the interior pressure
of the liquid. The valve stem can be made of glass, porcelain, or other suitable
material and the upper end of the stem is made of a size such that it will not pass
through the hole at the bottom of the stopper; the lower end of the stem is provided
with a shoulder or set off in order that the washer may not be blown up against the
seat during the filling. The washer, which is large enough to cover the hole in the
bottom of the stopper so as to form a joint, fits into a groove in the stem below
the shoulder or set off. In some cases I provide the valve stem with ribs or projec-
I
tions so as to allow a free passage for the liquids to pass into the bottle, or
groove the
stem for the same object and in some cases I form ribs or projections at the bottom of
the stopper so that the valve will not fall too low, or I otherwise provide a suitable
passage for the liquids to pass.

page_text: It will be obvious that instead of forming the stem with a shoulder or set off I can
perforate the stem.
When my improved valve screw stoppers are moulded out of such plastic material
as lionite mould such hollow stoppers with a tube of ebonite or metal inside the
stopper for the purpose of strengthening the stopper, and the tube is made with a
number of holes, so that the plastic composition will be pressed into the holes and
become securely attached to the tube, or I form the outside of the tube rough or with
a number of grooves or other projections so that the plastic material will be securely
fixed to the tube.

I, HENRY BARRETT, of 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 :-
This invention relates to improvements in valve screw stoppers for bottles for
containing aërated or gaseous liquids.
In the manufacture of such stoppers according to the present invention I mould or
otherwise make a hollow screw stopper, that is to say, a screw stopper with a hole
passing right through it, the said hole being adapted to receive a valve through which
charge or fill the bottle with liquid. The valve consists of a stem fitted with a
rubber or cork washer; the object of the washer is to make a joint against the bottom
of the stopper or the upper part thereof as the case may be by the interior pressure of
the liquid. The valve stem can be made of glass, porcelain or other suitable material
and the upper end of the stem is made of a size such that it will not pass through
the hole in the stopper. The washer, which is large enough to cover the lower end
of the hole in the stopper so as to form a joint, fits into a groove in the stem. In
some cases I provide the valve stem with ribs or projections so as to allow a free
passage for the liquids to pass into the bottle, or I groove the stem for the same object
and in some cases I form ribs or projections at the part of the stopper on which the
upper end of the valve stem rests, so that the valve will not fall too low, or I otherwise
provide a suitable passage for the liquids to pass.
It will be obvious that instead of forming the stem as hereinbefore described I can
perforate the stem.
When a very light stopper is required I make it of thin metal such as tinned iron
or steel.
In order to enable my invention to be fully understood. I will proceed to describe
how it can be carried into practice by reference to the accompanying drawing in
which figure 1, represents a vertical section of a valve screw stopper constructed
according to my invention, the valve seating being formed at the bottom of the
stopper; figure 2 is a similar view to figure 1 but shewing the valve seating formed
near the upper part of the stopper; figures 3 and 4 are detached elevations of the
valves of the valve screw stoppers shewn in figures 1 and 2 respectively. Figure 5
is a vertical section of a light sheet metal valve screw stopper made according to my
invention. Similar letters in all the figures represent similar parts.
Referring to figures 1 and 3 a, represents the screw stopper which is here shewn
with a hole b, passing right through it the upper part of the hole being of greater
diameter than the lower part thereof; c, c¹, represent the stem of the valve which is
grooved so as to allow the bottle to be charged or filled with liquid; d, is the rubber

page_text: or cork washer which fits in a groove in the lower part c, of the valve stem and is
large enough to cover the lower end of the hole b, and serves to make a tight joint
against the bottom of the stopper a, by the interior pressure of the liquid; the upper
end c', of the valve stem is made as shewn of a size such that it will not pass through
the smaller portion of the hole b, in the stopper; e, e, e, are the grooves which I form
in the stem c, c', of the valve to allow a free passage for the liquid to pass into the
bottle, is the usual washer below the shoulder of the stopper a.
By this construction the stopper having been introduced into the mouth of a bottle
to be filled the valve will be in its open position as shewn in figure 1 and the bottle
can be filled through the stopper in any suitable machine, which will keep the valve
in its open position, the liquid passing through the hole b, and grooves e, e, e; when
the bottle has been filled and pressure removed from the stem c, c', of the valve the
washer d, will be forced against the bottom of the stopper a, by the pressure within
the bottle so as to make a tight joint and hermetically close the bottle.
required to open the bottle the valve can be easily opened by pressing the same
downwards so as to release the excess of gas from the bottle previous to unscrewing
the stopper a.
When it is
The valve stopper illustrated in figures 2 and 4 is similar to that shewn in
figures 1 and 3 except that the seating for the valve is made at the upper part of the
stopper a, and it will be understood without further description.
Figure 5 illustrates my hollow valve screw stopper made of suitable sheet metal;
the valve stem in this case can be made much smaller than those shewn in figures 1
to 4, the whole forming a very light stopper.
When my improved valve screw stoppers are moulded out of such plastic material
as lionite I mould such hollow stoppers with a tube of ebonite or metal inside the
stopper for the purpose of strengthening the stopper and the tube is made with a
number of holes, so that the plastic composition will be pressed into the holes and
become securely attached to the tube, or I form the outside of the tube rough or
with a number of grooves or other projections so that the plastic material will be
securely fixed to the tube.
I have shewn my improved valve screw stoppers with the passages for the intro-
duction of the liquid formed by grooving the stem c, c', of the valve but it will be
obvious that such grooves can if required be made in the sides of the hole b, or the
passages can be formed by providing the said valve stem or the said hole with feathers
or projections or the stem itself may be perforated by a hole passing from the upper
part of the stem and opening just above the elastic washer.
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 :-
The improved valve screw stoppers for bottles for containing aërated or gaseous
liquids hereinbefore described and illustrated in the accompanying drawing.
