HENRY BARRETT, of Hampton, in the County of Middlesex. "IMPROVEMENTS
IN STOPPING OR CLOSING BOTTLES, JARS, AND SIMILAR VESSELS, AND APPARATUS
CONNECTED THEREWITH,"
This Invention relates to simple, cheap, and efficient methods of closing or
stopping bottles containing beer, wine, or other liquid, whether gaseous or otherwise,
also applicable to closing jars and similar vessels, the improved stoppers allowing
of the bottles or other vessels being easily opened.
In one modification of my Invention I form the interior of the neck of the
bottle or other vessel with a quick coarse female screw thread, and the stopper is
formed with a corresponding male screw made of any suitable plastic material.
The said male screw is formed with a head or cap, and in a recess in the shoulder
of which I place a seating or packing of cork, india rubber, or of combined cork
and india rubber. The said stopper may in some cases with advantage be
perforated with one or more.holes passing from the bottom thereof to the periphery
just beneath the shoulder for the purpose hereinafter described, and when the
stopper is used with bottles containing aërated or gaseous liquids it may be
advantageous to form the stopper with a central valve opening downwards. If
the stopper is to be fastened to the bottle this may be effected by moulding a
piece of wire in the head of the stopper, the ends of such wire being bent down-
wards, and connected hingewise to two half rings on the neck of the bottle under
the rim, and which can turn on or around the neck of the bottle.
To fill a bottle provided with a stopper constructed as bereinbefore described,
the stopper is partly screwed into the neck of the bottle, the bottle is then placed in
the filling machine, and the beer, wine, or other liquid will pass into the bottle
through the herein before described holes or perforations in the stopper. As soon
as the bottle is sufficiently full the bottle is partly turned, whereby the stopper is

page_text: screwed down, and the clastic seat therein bears tightly on the top of the mouth of
the bottle, and forms a close and air tight joint.
To enable the bottle to be turned so as to close the stopper the filling or bottling
machine is provided with a lever, a cam, or gearing operated by the treadle of the
machine or otherwise, according to the construction of inachine employed.
To open the bottle it is merely necessary to turn or unscrew the stopper, and the
contents or part of the contents of the bottle may be poured out, and the stopper
may be screwed back into its seat or not, as required.
In another modification of my Invention, applicable to bottles for aërated or
gaseous waters or beer, I dispense with the screw thread in the neck of the bottle
and on the stopper, and construct the stopper of a cylindrical cap in which works a
piston or valve, and between the bottom of the cap and the mouth of the bottle
I place a diaphragm of suitable material. A band or its equivalent passes over
the cap and is suitably connected to the bottle.
By this arrangement the internal pressure will force up the piston against the
band, and thus form a tight joint.
My improved stoppers being made of plastic material can be made of any
required shape or design on the upper part, and be stamped with a name, device or
trade mark as required, and bottles so stoppered would not require capsules.

This Invention relates to simple, cheap, and efficient methods of closing or
stopping bottles containing beer, wine, or other liquid, whether gaseous or otherwise,
also applicable to closing jars and similar vessels, by the use of stoppers of an
improved construction allowing of the bottles or other vessels being easily opened.
In one modification of my Invention I form the interior of the neck of the
bottle or other vessel with a quick coarse female screw thread, and the stopper is
formed with a corresponding male screw made of any suitable plastic material. The
said male screw is formed with a head or cap, and in a recess in or below the
shoulder of which I place a seating or packing of cork, india rubber, or of combined
cork and india rubber. The said stopper is perforated with one or more holes
passing from the bottom thereof to the periphery just beneath the shoulder for the
purpose hereinafter described, and when the stopper is used with bottles con-
taining aërated or gaseous liquids it may be advantageous to form the stopper with
a central valve opening downwards.
If the stopper is to be fastened to the bottle this may be effected by moulding a
piece of wire in the head of the stopper, the ends of such wire being bent down-
wards, and connected hingewise to two half rings on the neck of the bottle under
the rim, and which can turn on or around the neck of the bottle.
To fill a bottle provided with a stopper constructed as hereinbefore described,
the stopper is partly screwed into the neck of the bottle, the bottle is then placed
in the filling machine, and the beer, wine, or other liquid will pass into the bottle
through the herein before described holes or perforations in the stopper. As soon
as the bottle is sufficiently full the bottle is partly turned, whereby the stopper is
screwed down, and the elastic seat therein bears tightly on the top of the mouth of
the bottle, and forms a close and air tight joint.
To enable the bottle to be turned so as to close the stopper the filling or bottling
machine is provided with a lever, a cam, or gearing operated by the treadle of the
machine or otherwise, according to the construction of machine employed.
To open the bottle it is merely necessary to turn or unscrew the stopper, and
the contents or part of the contents of the bottle may he poured out, and the
stopper may be screwed back into its seat or not, as required.
In another modification of my Invention, applicable to bottles for aërated or
gaseous waters or beer, I dispense with the screw thread in the neck of the bottle
and on the stopper, and construct the stopper of a cylindrical cap in which works
a piston or valve, and between the bottom of the cap and the mouth of the bottle
I place a ring or diaphragm of suitable material. A band or its equivalent passes
over the cap and is suitably connected to the bottle.
By this arrangement the internal pressure will force up the piston against the
band, and thus form a tight joint.
My improved stoppers are made of plastic material of any required shape or
design on the upper part, and may be stamped with a name, device, or trade mark
as required, and bottles so stoppered would not require capsules.
In order to make my Invention better understood I will now proceed to describe
the same by reference to the accompanying Drawing, in which Figure 1 is a
sectional elevation of a screw stopper and bottle neck constructed according to my
improvements; Figure 2 is a sectional view of the stopper, and Figure 3 is an
elevation of a machine suitable for charging with gas bottles stoppered with my

page_text: improved screw stopper; Figure 4 is an elevation, and Figure 5 a section of the
improved external stopper constructed according to the second part of my
Invention.
I will first describe the bottle and stopper shewn in Figures 1 and 2, in which A
represents the neck of the bottle, the interior of which is formed with a quick
coarse female screw thread a, such screw thread a commencing a short distance
below the top of the neck, the portion of the neck b above the screw thread being
formed of a conical shape, the base of the cone being upwards; B is the stopper,
which is formed with a male screw thread c corresponding with the screw thread a
in the bottle neck; the angle of the conical part d of the stopper above the thread c
is greater than the angle of the conical part b of the neck, so as to leave an angular
space between this part of the stopper and the conical part of the neck, as shewn ;
fis the head or cap of the stopper; g is the seating or packing consisting of a ring
of vulcanized india rubber, or other suitable material, such as cork or combined
cork and india rubber, and such ring g is placed in a groove at the bottom part of
the conical portion of the stopper, as shewn.
If a stopper of this construction be placed in the mouth of a bottle formed to
receive it, as shewn in Figure 1, and about half a turn be given to the stopper (or
to the bottle) the stopper will be driven home, that is to say, a tight joint will be
formed by means of the seating g being tightly compressed between the conical
portion of the bottle and the stopper; the dotted lines, Figure 1, shew the holes
which are sometimes made in the stopper.
Figure 3 shews an elevation partly in section of a form of inachine which I find
may be used with advantage for charging with gas, bottles constructed and
stoppered as herein before described, and when such bottles have been filled with
beer or other malt liquor.
This machine consists of a suitable framework on which I place a bar C, to
which I fix a number of sockets or cups D adapted to receive the necks or mouths
of the bottles A; each of these sockets or cups is fixed to a fulcrum, so as to allow
a rocking motion to be communicated to it.
In the bottom part of each cup works a smaller socket E fitting over the head of
the stopper. Each socket has a spindle F passing screw-wise through a stuffing
box G; at the bottom of the socket and to the end of each spindle F I-fit a small
hand wheel H; I is a pipe leading from a gas generator, such pipe being in com-
munication with the interior of each cup or socket. At a suitable distance above
the lower bar C I provide a sliding or rocking bar J fitted with clutches or clasp
rings K for clasping or holding the punts of the bottles, and above each of these
clasps is a set screw L or other suitable device for holding and keeping the bottle
necks tightly wedged into the sockets or cups D. A number of bottles filled with
beer and closed by the improved stoppers hereinbefore described are placed one in
each socket D with the bottom upwards, as shewn, the punts of the bottles being
placed in the rings or clasps K.; the set screws L are screwed down, so as to press
the mouths of the bottles well into the sockets D; I then open the communication
between the generator and the sockets or bottles, and then by means of the small
sockets, spindles, and wheels, I unscrew the stoppers from the bottles until the ends
only of the screw parts of the stoppers remain in the coues of the bottle necks (or
the stoppers may be drawn free of the bottles altogether). The gas will now enter
the contents of the bottles, the rocking bar J is then set in motion by any suitable
arrangement so as to cause the bottles to oscillate or rock backwards and forwards,
by which means the beer will more quickly receive the gas. The contents of the
bottles having been thus charged the gas is shut off, the stoppers are screwed in,
and the bottles are detached from the machine and replaced by others.
When using my improved screw stopper for gaseous liquids I reverse the position
of the bottles and machine and fill in the usual manner.
I will now describe the stopper shewn in Figures 4 and 5 of the Drawing.
A is the bottle, and N is the cylindrical cap in which works the piston O; P is
the diaphragm or ring; Q is the band (or its equivalent) passing over the cap and

page_text: connected to the bottle neck by means of a wire R. The band Q is jointed to the
arins S, S, which are jointed at V to the rod T of the piston O. By this arrange-
ment the internal pressure will force up the piston O against the arms S, S, at the
top joint V, thus drawing the arms S, S, inwards, causing the band Q at the
points W, W, to press against the cylindrical cap N, and force it down on the ring
or diaphragm P of india rubber, and it is at this point the joint is made between
the bottle and the stopper. It is to be understood that the piston O acts as a cork
fitting the neck of the bottle, and is just tight enough to allow of its being acted
upon by the pressure. It will thus be seen that as the surface of the piston O is
greater than the surface of the cylindrical cap pressing against the mouth of the
bottle extra pressure is obtained upon the piston, and this extra pressure is
utilized for obtaining a more perfect joint. In the caso of bottled beer it is
desirable that the gas formed in the beer at the commencement, together with a
portion of the air, should be allowed to escape, so as to improve the beer by the
escape of such air as may remain in the bottle at the time of filling. Now by this
arrangement when a bottle is filled with beer the stopper is placed in the bottle;
the bottle is imperfectly corked, that is to say, that although any external air is
excluded from passing into the bottle, yet at the commencement of the formation
of gas in the bottle a slight internal pressure will allow both gas and air to escape,
but first the air, and as soon as a more active action or formation of gas takes
place the piston O is forced upwards, and the joint is made perfect as herein before
described, and as the internal pressure increases by the natural formation of gas,
the pressure against the piston is likewise increased, so that the greater the internal
pressure the more perfect is the resistance obtained.
Having thus described my said Invention and the manner of performing the
same. I wish it to be understood that I do not confine myself to the precise details
herein laid down and shewn in the Drawing, as the same may be varied without
departing from the peculiar character of my Invention; I also wish it to be under-
stood that I lay no claim to the employment of a simple screw stopper and bottle,
as such have been before proposed to be used, but what I do claim is,―
Firstly. Stoppering bottles by the use of a stopper formed with a cone and a
quick coarse male screw thread, an elastic seating being placed on the cone, and in
some cases having holes made in the stopper, as mentioned, in combination with a
bottle the interior of the neck of which is formed with a female screw thread, and
with a female cone of different angle to the conical part of the stopper, substantially
as hereinbefore described and represented in Figures 1 and 2 of the accompanying
Drawing.
Secondly. The construction and employment of the improved machine, shewn in
Figure 3 of the Drawing, for charging with gas bottles stoppered as hereinbefore
described and shewn in Figures 1 and 2 of the Drawing.
Thirdly. The use of stoppers for closing bottles so constructed that the closing
is effected by the internal pressure of the liquid acting on the device or stopper,
substantially as herein before described and represented in Figures 4 and 5 of the
Drawing or any mere modification thereof.
In witness whereof, I, the said Henry Barrett, have hereto set my hand
and seal, this Fifteenth day of April, in the year of our Lord One thousand
eight hundred and eighty.

This Invention relates to a simple, cheap and efficient methods of closing or
stopping bottles containing beer, wine, or other liquid, whether gaseous or otherwise,
also applicable to closing jars and similar vessels by the use of an improved stoppers
of an improved construction allowing of the bottles or other vessels being easily
opened.
In-on-modifiention of According to my Invention 1 form the interior of the neck of
the bottle or other vessel with a quick coarse female serew thread and the stopper is
formed with a corresponding male screw made of any suitable plastic material, the
said male screw is formed with a head or cap and in a recess in or below the
shoulder of which I place a seating or packing of cork, india rubber or of combined
cork and india rubber The said stopper is perforated with one or more holes
passing from the bottom thereof to the periphery just beneath the shoulder for the
purpose hereinafter described and when the stopper is used with bottles con-
taining aërated or gaseous liquids it may be advantageous to form the stopper with
a central valve opening downwards.
If the stopper is to be fastened to the bottle this may be effected by moulding a
piece of wire in the head of the stopper the ends of such wire being bent down-
wards and connected hingewise to two half rings on the neck of the bottle under
the rim, and which can turn on or around the neck of the bottle.
To fill a bottle provided with a stopper constructed as hereinbefore described
the stopper is partly screwed into the neck of the bottle, the bottle is then placed
in the filling machine and the beer, wine or other liquid will pass into the bottle
through the hereinbefore described holes or perforations in the stopper. As soon
as the bottle is sufficiently full the bottle is partly turned whereby the stopper is
screwed down and the elastic seat therein bears tightly on the top of the month of
the bottle and forms a close and air tight joint.
To enable the bottle to be turned so as to close the stopper the filling or bottling
machine is provided with a lever, a cam or gearing operated by the freadle of the
machine or otherwise according to the construction of machine employed.
To open the bottle it is merely necessary to turn or unscrew the stopper and
the contents or part of the contents of the bottle may be poured out and the
stopper may be screwed back into its seat or not as required.
In another modifiention of my Invention applicable to bottle: for nerated or
20us waters or beer! dispense with the screw thread in the neek of the bottle
and on the stopper and construct the stopper of a cylindrical-cap, in which works
+iston-or-valve-and-between the bottom of the cap and the month of the bottle
-place-a-ring-or diaphragm of suitable material. A band or equivalent passes
ver the cap and is suitably connected to the bottle.
By this arrangement the internal pressure-will force up the piston against-the
and and thus form a tight joint.
My improved stoppers are made of plastic material of any required shape or
lesign on the upper part, and may be stamped with a name, device, or trade mark
is required and bottles so stoppered would not require capsules.
In order to make my Invention better understood I will now proceed to describe
he same by reference to the accompanying Drawing in which Figure 1, is a
ectional elevation of a screw stopper and bottle neck constructed according to my
provements Figure 2, is a sectional view of the stopper and Figure 3, is an
levation of a machine suitable for charging with gas bottles stoppered with my

page_text: improved screw stopper; igara-1 is an elevation and iga sertion of the
improved external stopper constracted according to the second-part-of-nor
Invention.
I will first describe the bottle and stopper-shewn In Figures 1 and 2, in which A,
represents the neck of the bottle the interior of which is formed with a quick
coarse female screw thread a, such screw thread a, commencing a short distance
below the top of the neck the portion of the neck above the screw thread being
Formed of a conical shape the base of the cone being upwards; B, is the stopper
which is formed with a male screw thread, corresponding with the screw thread,
in the bottle neck, the angle of the conical part d, of the stopper above the thread e,
is greater than the angle of the conical part of the neck, so as to leave an angular
space between this part of the stopper and the conical part of the neck as shown;
is the head or cap of the stopper, is the seating or packing consisting of a ring
of vulcanized india rubber or other suitable material such as cork or combined
cork and india rubber, and such ring, is placed in a groove at the bottom part of
the conical portion of the stopper as shewn.
If a stopper of this construction he placed in the mouth of a bottle formed to
receive it, as shewn in Figure 1, and about half a turn be given to the stopper. (or
to the bottle) the stopper will be driven home, that is to say, a tight joint will be
formed by means of the seating, being tightly compressed between the conical
portion of the bottle and the stopper; the dotted lines Figure 1, shew the holes
which are sometimes made in the stopper.
Figure 3, shows an elevation partly in section of a form of machine which I find
may be used with advantage for charging with gas. bottles constructed and
stoppered as hereinbefore described, and when such bottles have been filled with
beer or other malt liquor, but no claim is made to this machine.
Thise machine consists of a suitable framework on which I place a bar C, to
which I fix a number of sockets or cups D, adapted to receive the necks or mouths
of the bottles A each of these sockets or cups is fixed to a fulcrum so as to allow
a rocking motion to be communicated to it.
In the bottom part of each cup works a smaller socket E, fitting over the head of
the stopper. Each socket has a spindle F, passing screw-wise through a stuffing
box at the bottom of the socket and to the end of each spindle F. I fit a small
hand wheel H; I, is a pipe leading from a gas generator, such pipe being in com-
munication with the interior of each cup or socket. At a suitable distance above
the lower bar C, I provide a sliding or rocking bar J. fitted with clutches or clasp
rings K, for clasping or holding the punis of the bottles, and above each of thes
clasps is a set screw L, or other suitable device for holding and keeping the bottle
necks tightly wedged into the sockets or cups D. A number of botiles filled with
beer and closed by the improved stoppers herein before described are placed one in
vach socket D, with the bottom upwards as shewn, the punts of the bottles being
placed in the rings or clasps K, the set screws L, are screwed down so as to press
the months of the bottles well into the sockets D. I then open the communication
between the generator and the sockets or bottles and then by means of the small
sockets, spindles, and wheels I unscrew the stoppers from the bottles until the ends
only of the screw parts of the stoppers remain in the cones of the bottle necks (or
the stoppers may be drawn free of the bottles altogether). The gas will now enter
the contents of the bottles, the rocking bar J, is then set in motion by any suitable
arrangement, so as to cause the bottles to oscillate or rock backwards and forwards,
by which means the beer will more quickly receive the gas. The contents of the
bottles having been thus charged, the gas is shut off, the stoppers are screwed in,
and the bottles are detached from the machine and replaced by others.
When using my improved screw stopper for gascous liquids, I reverse the position
of the bottles and machine and fill in the usual manner.
1 will now describe the stopper shewn in Figures 1 and 6 of the Drawing,
A. ie the bottle end N, is the exlindrical cap in which works the picton 0+18
the diaphragm-or-ring is the band-(-or-its equivalent) passing over the cap and

page_text: connected to the bottle neck by means of a wire R. The band Q is jointed to the
SS, which are jointed at V-to the rod T of the piston Q. By this arrange-
ment the internal pressure will force-up-the-piston-0, against the arms S. S, at the
top joint V: thes drawing the arms inwards causing the band at the
points WWtress against the lindrical cap Ny and fove it down on the ring
or-ding hangm P, of indin rubber, and it is at this point the joint is made between
the bottle and the stopper. It is to be understood that the piston (), acts us a cork
fitting the week of the bottle and is just tight enough to allow of its being neted
upon by the pressure. It will thus be seen that, no the surface of the piston 0-
greater than the surface of the cylindrical cap pressing against the month of the
hettle, exim pressure is obtained upon the piston, and this extre pressure is
tilized for obtaining a more-perfect-joint. In the case of battled heer, it is
desirable that the gas formed in the beer at the commencement: together with a
tortion of the air, chould be allowed to escape so us to improve the beer by the
europe of mach air as may remain in the bottle at the time of filling. Now by this
arrangement, when a bottle is filled with beer, the stopper is placed in the bottle;
the hottle is imperfectly-corked, that is to say that although any external air is
excluded from passing into the bottle, yet at the commencement of the formation
of gas in the bottle a slight internal pressure will allow both gee and air to escape;
but first the nir, and ne roon-a-8-more-native-action or formation of gas-takes
place, the piston O, is forced upwards and the joint is made perfect as hereinbefore
described, and as the internal pressure increases by the natural formation of gus
the pressure against the piston is likewise increased, so that the greater the internat
pressure the mere perfect is the resistance obtained.
Having thus described my said Invention and the manner of performing the
same I wish it to be understood that I do not confine myself to the precise details
herein laid down and shown in the Drawing as the same may be varied without
departing from the peculiar character of my Invention; I also wish it to be under-
stood that I lay no claim to the employment of a simple screw stopper and botile
as such have been before proposed to be used But what I do claim is
Firstly: Stoppering bottles by the use of a stopper, formed with a cone and a
quick coarse male screw thread, an elastic seating being placed on the cone, and in
some cases having holes made in the stopper as mentioned, in combination with a
bottle the interior of the neck of which is formed with a female screw thread and
with a female cone of a different angle to the conical part of the stopper, substantially
as hereinbefore described and represented in Figures 1 and 2 of the accompanying
Drawing.
Secondly. The construction-and-employment of the improved machine chewn in
Figure 8, of the Drawing for charging with gas, bottles stopy ered ne hereinbefore
described and shown in Figures 1 and 2 of the Drawing:
Thirdly. The use of stoppers for closing bottles, so constructed that the closing
is effected by the internal pressure of the liquid neting on the device or stopper
substantially as hereinbefore described and represented in Figures 1 and 5 of the
Drawing or any mere modification thereof.
In witness whereof the said Henry Barrett have hereto set my hand
and seal this Fifteenth day of April in the year of our Lord, One thousand
