Improvements in or Applicable to Bottles for Containing Aërated
or Gaseous Liquids, and in Apparatus Employed in
Manufacture of such Bottles.
the
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 that class of bottles which have internal stoppers that are
kept to their seat by the pressure of gas contained in the bottle, and which are
provided with valves below the seating for the purpose of facilitating the opening of
such bottles, and which opening is frequently accompanied with danger.
For this purpose I form a screw-threaded hole in the side of the neck of the bottle
and into this hole I fit a small screw stopper fitted with a ring or washer under the
head or at any other suitable part of the stem. The hole in the bottle neck is formed
while the bottle is being made. For this purpose I fit a screw-pin or stud in one of
the sides of the mould which forms the neck of the bottle; this screwed pin projects
inside the mould and is so arranged that it can be screwed in and out of the mould.
The bottle is blown in the mould, the screwed pin is then withdrawn from the inside
of the mould leaving a screwed hole in the neck of the bottle. In some cases I make
the screwed pin hollow with a small punch passing through the centre and with a
coned point, so that I am able to clear away any metal which may form at the end of
the screwed pin.
In cases where I require the hole to extend through the bottle the whole size of the
threaded hole, I fit the hollow screw-pin which fits in the side of the mould for
forming the screwed hole in the neck of the bottle, with a sliding punch as before
described, only instead of having a cone point I make the end of the punch with a
projection or point on the one side at the end the full size of the screw so that
when the bottle is finished, and before the screw is removed, the punch in the centre
of the outer screw may be turned which will score or groove the metal at the end of
the hole; when the bottle is cold the end can be knocked off.
In some cases the screw pin or stud is adapted to fit loose in the mould which
arrangement allows of the bottle with the screw pin therein being removed from the

page_text: mould whereby the said pin can be retained in the hole in the bottle until the latter
is finished and the pin is then unscrewed from the bottle, which arrangement obviates
the risk of the screwed hole getting out of shape as may sometimes happen if the pin
is removed before the bottle is finished.
In order that the small screw stopper may not get disconnected from the bottle and
lost, I propose to make the end of the stopper hollow, and by means of a suitable tool
I expand the end of the small stopper after it is fitted to the bottle so that the end is
larger than the hole and will not pass through. The small screw stopper may be made
of any suitable metal, such as tin, or it may be made of material such as ebonite, or
of glass or the like material. In some cases I fit the hole in the side of the neck of the
bottle with a hollow stud having a head and a washer, and I then screw into the hollow
stud the small screw stopper; in such cases the hole in the neck may be a plain hole
and is not required to be screwed or made with a thread. Or in some cases I fit the
hole with a stud having a head on the inside of the neck, and on the end which
projects outside the bottle I fit or screw a hollow nut, between which and the bottle I
place an india-rubber washer. Instead of fitting the screw plug from the outside of
the bottle neck as above described I can fit the bottle from the inside, making the joint
inside and allowing the stem of the plug to project through the neck when I split the
end of the screw and turn the ends so as to form a means by which the screw can be
turned from the outside, in which case the hole would have to be made from the inside
of the bottle, or it would have to be faced so as to form a smooth seating for the
india-rubber washer which is fitted under the head of the plug.
Instead of splitting the ends of the small screw I sometimes form the head of the
same when made of metal or like flexible material, with a projection which, when the
screw has been screwed home, can be bent so as to rest against a projection formed
on the bottle neck whereby the screw will be prevented from being accidentally
turned when it is required to open the valve to release the gas in the bottle the said
projection is bent outwards and can then serve as a lever by which to turn the screw.
Further instead of placing the ring or washer under the head of the screw as
herein before described, it can be placed between the inner end thereof and the outer
face of the hole in which the screw is placed, which hole is reduced at this point so
as to confine the ring or washer.

the
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 :-
This invention relates to that class of bottles which have internal stoppers that are
kept to their seats by the pressure of gas contained in the bottle and which are
provided with valves below the seating for the purpose of facilitating the opening of
such bottles and which opening is frequently accompanied with danger.
For this purpose I form or provide a screw-threaded hole in the side of the neck of
the bottle and into this hole I fit a small screw stopper fitted with a ring or washer
under the head or at any other suitable part of the stem. The hole in the bottle neck
may with advantage be formed while the bottle is being made.
In order to enable my invention to be fully understood I will describe how it can
he carried into practice by reference to the accompanying drawings in which figures
1, 4, 5, 6, 7 and 8 represent views of the necks of bottles illustrating my improve-
ments in the same; figures 2, 3, 9, 10 and 11 are views illustrating the apparatus 1
employ in the manufacture of such bottles. Similar letters in all the figures represent
similar or corresponding parts.
Figure 1 is a section of a bottle neck formed with a screw-threaded hole according
to my invention; a, is the small screw stopper which I fit in the said hole; b, is the
ring or washer which in this arrangement is shewn placed under the head c, of the
stopper a; The small screw stopper may be made of any suitable metal, such as tin or
it may be made of material such as ebonite or of glass or the like material. When
the said material is of a nature suitable for the purpose I find it advantageous in
order to prevent the small screw stopper a, from becoming disconnected from the
bottle and lost to make the end of the stopper hollow as shewn by the dotted line and
by means of a suitable tool to expand or upset the end of the small stopper after it is
fitted to the bottle so that the end is larger than the hole and will not pass through.
By this construction it will be seen that if a bottle provided with a valve as
described be filled with aërated or gaseous liquid, in order to relieve the bottle from
the internal pressure of the gas prior to pressing in the internal stopper of the bottle,
it is only necessary to screw out the stopper a, by its head c, sufficiently to remove
pressure from the ring or washer b, when the gas will rush out between the stopper a,
and the hole as the one does not work air-tight within the other.
Figure 2 represents a section of part of a bottle in a bottle mould arranged to form
the hereinbefore-described screw-threaded hole in the neck of the bottle while the
latter is being made.
For this purpose I fit a screw-pin or stud d, in one of the sides of the mould A,
which forms the neck of the bottle B; the end of this screw-pin is reduced in size as
shewn at e, and projects inside the mould A, and is arranged so that it can be screwed
in and out of the mould by means of a handle f, on a rod g, carrying the screw-pin d;
this rod bears and works in a bracket h, fixed to the mould A ; i, is a collar or flange
on the rod g, forming a stop for preventing the screw d, e, from being screwed in or
out beyond a given distance.
In some cases as shewn in the. said figure I make.the screw-pin d, e, and rod y,

page_text: hollow and provide a small rod j, passing through the centre and having a projection
or point m, on one side at the inner end the full radius of the screw so that when the
bottle B, is moulded, and before the screw e, is removed, the rod j, in the centre
of the screw d, e, may be turned which will score or groove the metal at the end of
the hole; when the bottle is cold the projecting metal n, can be knocked off; o, is a
crank handle for rotating the rod j.
The screw-pin d, e, being placed in the position shewn in figure 2, the bottle is blown
in the mould A; the rod j, is then turned to score or groove the metal at the end of
the hole as herein before described and the screw-pin d, e, is then operated so as to
withdraw the reduced part e, from the inside of the mould; the bottle is then allowed
to cool and the projecting metal knocked off leaving a screwed hole in the neck of the
bottle.
Instead of forming the screw-threaded hole around a screw-pin or plug as
herein before described and illustrated in figure 2 I sometimes cut or score the screw-
thread in the hole as illustrated in figure 3 which represents a similar view to figure 2
but shewing suitable means for so forming the thread. The part e, of the screw-pin is
for this purpose made plain or smooth but with a projection or tooth o¹, and a wheel f,
is provided on the rod g, whereby the screw-pin d, e, can be rotated. By turning the
wheel, in the proper direction the end e, of the screw pin will be drawn out of the
bottle neck and will at the same time score or form the thread in the hole in the bottle
neck the projecting metal n, which in this case is formed by a conical point k, on
the inner end of the screw-pin is knocked off when the bottle has become cool thereby
leaving a screw-threaded hole right through the neck of the bottle..
Instead of fitting the screw plug or stopper a, figure 1, from the outside of the
bottle neck as described the bottle may in some cases be fitted from the inside (as
shewn in figure 4 which is a similar view to figure 1 but shewing this arrangement)
making the joint inside and allowing the stem of the plug or stopper to project
through the neck when I split the end of the screw as shewn and turn the ends so as
to keep the screw plug or stopper in its place and form a means by which the screw
can be turned from the outside in which case the hole would have to be made from the
inside of the bottle, or it would have to be faced so as to form a smooth seating for
the india rubber washer b, which is fitted under the head c, of the plug or stopper.
It will be obvious that instead of splitting and turning out the end of the screw
plug or stopper it can be arranged to be turned by other suitable means.
In some cases I fit the hole in the side of the neck of the bottle with a hollow
stud having a head and a washer or nut and I then screw into the hollow stud
the small screw stopper; in such cases the hole in the neck may be a plain hole
and is not required to be screwed or made with a thread. This arrangement is
shewn in figure 5 which is a vertical section of part of the neck of a bottle
provided with a plain hole for this purpose; a¹, is the hollow stud having a head c¹,
which stud is passed into the hole from the interior of the bottle and the washer or
nut p, is then screwed on the outer end; which has a screw-thread for that purpose;
a, is the small screw stopper which screws into the hollow stud a¹; the hole in the
stud a', is contracted in size at 9, and the washer b, is situated between the inner
end of the stopper a, and the surface formed by such contraction; c, is a turned down
handle for rotating the stopper a.
Or in some cases (as shewn in the vertical section of the bottle neck figure 6).
I fit the plain hole with a loose stud a, having a head c, on the inside of the neck
which is formed with a projection s, a recess t, being formed on the outside; on
the end which projects outside the bottle I fit or screw a nut r, between which and
the bottle I place an india rubber washer b, which fits in the recess t, and is
compressed by the nutr; the part of the stud a, which fits in the hole is preferably
formed square so as to prevent the stud from turning when screwing the nut on the same;
the outer end of the stud a, is upset so that the nut r, shall not be detached therefrom.
As shewn in figures 7 and 8 which represent an elevation and a section respectively
of part of a bottle neck I sometimes form the small stopper a, when made of a ductile
metal or like material with an axial projection which when the screw stopper a, has

page_text: been screwed home can be bent as shewn at c, so as to rest against a projection u,
formed on the bottle neck whereby the screw stopper a, will be prevented from being
turned too far in either direction; when it is required to open the valve to release
the gas in the bottle the said projection c, serves as a lever by which to turn the screw
stopper. Instead of placing the ring or washer b, under the head of the screw
stopper as herein before described and illustrated in figures 1 and 4 it can as shewn
in the said figure 8, be placed in a similar position to the washer shewn in figure 5, but
between the inner end of the screw stopper a, and the face of the screw threaded
hole in the bottle in which the screw stopper is placed, which hole is reduced at
so as to confine the ring or washer b.
2,
In cases where I require the inner portion of the hole to be reduced in size as just
described I fit the hollow screw-pin d, e, which fits in the side of the mould A, for
forming the screwed hole in the neck of the bottle with a rod j, as before described
when referring to figure 2, only instead of having the point on one side of the rod j,
I make the end of the rod with a straight conical point k; so as to form a punch (as
shewn in figure 9, which represents a section of a portion of a mould and bottle
illustrating the application of the said punch) so that I am able to form the small or
reduced hole or passage q, through the metal which forms at the end of the screw-pin;
the head 1, of the punch j, projects beyond the handle f, by which the screw-pin is
operated as shewn and when the bottle has been moulded the punch j, is pushed
inwards by means of its head I, thereby forming the said hole or passage q.
Figure 10 represents a section of a portion of a mould and bottle the mould being
provided with a similar screw-pin d, e, to that shewn in figures 2 and 9 except that
the rod or punch j, is dispensed with the screw pin being formed instead with a conical
point k, similar to that shewn in figure 3; it will be obvious that in this case in order
to form the small or reduced hole or passage the projecting metal formed at the end of
the screw-threaded hole will have to be knocked off after the bottle has become cool.
In some cases (as illustrated in figure 11, which is a vertical section of part of a
bottle and mould) the screw-pin or stud d, e, is adapted to fit loose in the mould A ;
the part d, of the pin in this case is not screw-threaded but fits loosely in a recess
in the mould corresponding in shape with the said part d; this arrangement allows
of the bottle, with the screw-pin de, therein being removed from the mould A, whereby
the said pin can be retained in the hole in the bottle B, until the latter is finished
and the pin d, e, is then unscrewed from the bottle, which arrangement obviates the risk
of the screwed hole getting out of shape as may sometimes happen if the pin is
removed before the bottle is finished.
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. The construction and application to bottles for containing aërated or gaseous
liquids of a small screw stopper in combination with and working in a screw-threaded
hole in the side of the neck of the bottle substantially as and for the purpose herein-
before described.
2. The manufacture and use of the improved bottles for containing aërated or
gaseous liquids herein before described and illustrated in figures 1, 4, 5, 6, 7 and 8
of the accompanying drawings.
3. The use in the manufacture of bottles having holes in the sides of the necks,
of the moulds and tools constructed and operating substantially as hereinbefore
described and illustrated in figures 2, 3, 9, 10, and 11 of the accompanying drawings.
