page_text: I HENRY BARRETT, of Charterhouse Buildings, Goswell Road, in the county of
Middlesex, Aërated Water Manufacturer do hereby declaro the nature of the said
invention for "IMPROVEMENTS IN STOPPERS FOR BOTTLES FOR CONTAINING AËRATED
OR GASEOUS LIQUIDS" to be as follows:-
This Invention relates chiefly. to improvements in that class of internal stoppers
for bottles which consist of a body of suitable material such as glass or porcelain of
greater specific gravity than water and provided with an india rubber ring for
forming a tight joint when the stopper is closed by the pressure within the bottle.
It is well known that the bodies of such stoppers when made from porcelain,
glass or like material are liable to become chipped at the ends from striking against
the bottle and from other causes whereby they become unfit for use and the parts
which are chipped or broken off frequently pass off with the liquid from the bottle
which is very objectionable. Such stoppers also from their weight will not readily
turn in the bottle and consequently it frequently happens that they do not properly
fall into their seats.
My improvements have for object to so construct the stopper that the ends
thereof are protected from chipping and at the same time the bottoms of the
stoppers are rendered more buoyant than the heads whereby the stoppers are
assisted in properly falling into their seats when the bottles are filled..
For these purposes I provide the bottom of the stopper with a ring or washer or
a disc of suitable material such as ebonite, wood or other suitable material or
I form the bottom part of the stopper of wood or other suitable material.
When using a ring of a material such as ebonite I form the base of the stopper
with a projecting end onto which I spring a ring of ebonite or like material; or the
projecting end or stem may be formed with a screw thread onto which
screwed a washer of wood, ebonite, xylonite or other suitable material; or instead
may be
of screw threading the projecting end it may be formed of a suitable shape to allow
the wooden or other washer to be shrunk or moulded thereon, the groove for the
usual elastic washer being in either case formed in the glass or porcelain body; or
the bottom part of the stopper, made of wood, ebonite or other suitable material,

being formed on the porcelain or glass body and forced or otherwise fitted into a
countersunk hole in the bottom part of the stopper.
Or, the bottom of the stopper may be formed with a central stem which fits into
a hole in the porcelain or glass body the two parts being held together by a pin
running through them crosswise or in any other suitable manner.
In this latter
arrangement the elastic washer is placed on the lower part of the stem between tho
flange of the wooden or other base and the under side of the glass or porcelain
body; or the lower end of a stem on the glass or porcelain body may be screwed
into a washer of wood, ebonite, xylonite or other suitable material.
By this construction it will be obvious that the upper part or heads of the
stoppers being heavier than the lower portions of the stoppers will readily fall into
their seats while the bottom parts of the stoppers being protected by, or formed of,
a material which is not brittle, chipping of the bottom parts of the stoppers will be
prevented.
In all cases the stoppers may be provided with openings or valves to allow of
discharging the gases so that the stoppers may be easily opened and without
splashing but to this no claim is mado.

page_text: I HENRY BARRETT of Charterhouse Buildings, Goswell Road, in the County of
Middlesex Aerated Water Manufacturer do hereby declare the nature of the said
invention for "IMPROVEMENTS IN STOPPERS FOR BOTTLES FOR
AERATED OR GASEOUS LIQUIDS" and in what manner the same is to be performed
to be particularly described and ascertained in and by the following, statement:
CONTAINING
This Invention relates chiefly to improvements in that class of internal stoppers
for bottles which consist of a body of suitable material such as glass or porcelain of
greater specific gravity than water and provided with an india rubber ring for
forming a tight joint when the stopper is closed by the pressure within the bottle.
It is well known that the bodies of such stoppers when made from porcelain, glass
or like material are liable to become chipped at the ends from striking against the
bottle and from other causes whereby they become unfit for use and the parts which
are chipped or broken off frequently pass off with the liquid from the bottle which
is very objectionable.
Such stoppers also from their weight will not readily turn in the bottle and
consequently it frequently happens that they do not properly fall into their seats.
My improvements have for object to so construct the stopper that the ends thereof
are protected from chipping and at the same time the bottoms of the stoppers are
rendered more buoyant than the heads whereby the stoppers are assisted in properly
falling into their seats when the bottles are filled.
For these purposes I provide the bottom of the stopper with a ring or washer or
a disc of suitable material such as ebonite wood or other suitable material or I form
the bottom part of the stopper of wood or other suitable material.
In order to enable my invention to be fully understood I will describe the same
by reference to the several figures of the accompanying drawing which shew various
stoppers constructed according to my invention and in which figures similar letters
refer to parts which are similar.
Figures 1 and 2 represent an elevation and a section respectively showing a stopper
as constructed when using a ring a of a material such as ebonite in which case I form
the base of the stopper c with a projecting end d onto which I spring the ring a
of ebonite or like material; e in the section shews the usual india rubber washer
with which the stoppers are provided and f,f are openings or valves with which
they may be formed to allow of discharging the gases so that the bottles may be
easily opened and without splashing but no claim is made to these openings or
valves; or, as shewn in the elevation and section at figures 3 and 4 the projecting
end or stem d may be formed with a screw thread on to which may be screwed a
washer a of wood, ebonite, xylonite, or other suitable material; or instead of screw
threading the projecting end d it may be formed of a suitable shape such as is shewn
in figure 2 to allow the wooden or other washer to be shrunk or moulded thereon
the groove g for the clastic washere being in each case formed in the glass or
porcelain body as shewn in figures 1 and 3; or as represented in figures 5 and 6 in
elevation and section respectively, the bottom part 6 of the stopper, made of wood,
cbonite or other suitable material, may be formed with a groove g to receive the
washer e a suitable projection or hub h being formed on the porcelain or glass body c
and forced or otherwise fitted into a countersunk hole in the bottom part 6 of the
stopper.
•
Or, as shewn in elevation at figure 7 and in section at figure 8 the bottom b of
the stopper may be formed with a central stem i which fits into a hole in the
porcelain or glass body c the two parts being held together by a pin ǹ running

page_text: through them crosswise or in any other suitable manner such as that shewn in
section at figure 10, in which the central stem i, is screw-threaded and screws into
a screw threaded recess in the porcelain or glass body c or the screw threads may be
omitted and the recess in the body may be undercut and the bottom part of the
stopper be forced therein as shewn in the section at figure 12. Figures 9 and 11
are elevations of figures 10 and 12. In the arrangements shewn in figures 8, 10
and 12 the elastic washer is placed on the lower part 6 of the stem of the stopper
between the flange of the wooden or other base and the under side of the glass or
porcelain body c; or the lower end of a stem d on the glass or porcelain body c may
be screwed into a washer a of wood ebonite, xylonite or other suitable material
in the manner shewn in the sectional view at figure 14 of which figure 13 is an
elevation.
In the elevations of stoppers shewn in figures 1, 3, 5, 7, 9, 11 and 13 the elastic
washers are omitted for the sake of clearness.
By the construction of stoppers above described it will be obvious that the upper
parts or heads of the stoppers being heavier than the lower portions of the stoppers
will readily fall into their seats while the bottom parts of the stoppers being pro-
tected by, or formed of, a material which is not brittle, chipping of the bottom
parts of the stoppers will be prevented.
In all cases the stoppers may be provided with openings or valves similar to those
shewn in figure 2 to allow of discharging the gases so that the stoppers may bo
easily opened and without splashing but to this no claim is made.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declaro that what
I claim is:
(1) Providing the bottoms of the glass or porcelain bodies of internal stoppers with
a ring or washer or a disc of suitable material such as ebonite or wood or forming
the bottom parts of such stoppers of wood or other suitable material as and for the
purposes hereinbeforo described.
(2) The improved stoppers for bottles for containing aërated or gaseous liquids
herein before described and represented in the several figures of the accompanying
drawing.
