PROVISIONAL SPECIFICATION.
An Improved Internal Stopper for Bottles or other Vessels
Containing Aërated Waters or Liquids.
I, WILLIAM SAMSON, of 1 Urquhart Street, Dundee, in the County of Forfar,
Scotland, Aërated Water Manufacturer, do hereby declare the nature of this
invention to be as follows:-
:-
This invention which relates to an improved stopper for bottles or other vessels
containing aërated waters or liquids, has for its object to produce a floating stopper
which shall have at all times its larger diameter situated upwards; so that the
pressure of the gas in the aërated water forces it up into the neck of the bottle or
other vessel, to close the said aperture.
The stopper-which is an improvement upon my previous Patents Nos. 14755 of
1st December A.D. 1885, and 8595 of 12th June 1888-is fitted with a piece or
pieces of metal, glass, porcelain or other suitable material which is of greater
specific gravity than cork, in such a manner that the stopper at all times floats on
the liquid with its greater diameter upwards.
The ballast may be in the form of a cylinder, frustum of a cone or otherwise and
is fixed to the bottom of the stopper by being screwed into it, or by reducing the
diameter of the portion which passes through the stopper and fastening it by a nut
or washer at the other side.
The stopper in its natural condition is necessarily larger than the aperture in the
neck of the vessel, and in order to get it thereinto, it is placed in hot water or
otherwise made soft or readily compressible; and in that state it is pushed into the
bottle or other vessel.
The aperture in the neck of the vessel is made in two diameters, the larger of
which is towards the inside, thus forming an annular seat.
The stopper is made of cork and is cylindrical in shape, its length being preferably
less than its diameter or even its radius.

An Improved Internal Stopper for Bottles or other Vessels
Containing Aërated Waters or Liquids.
I, WILLIAM SAMSON, of 1 Urquhart Street, Dundee, in the County of Forfar,
Scotland, Aërated Water 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 which relates to an improved stopper for bottles or other vessels
containing aërated waters or liquids, has for its object to produce a floating stopper
which shall have at all times its larger diameter situated upwards; so that the
pressure of the gas in the aerated water forces it up into the neck of the bottle or
other vessel, to close the said aperture.

page_text: And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended an explanatory sheet of drawings, in the several figures of which corre-
sponding parts are marked with the same numerals of reference.
Figure 1. shows, in part sectional elevation, a bottle provided with my improved
internal stopper; Figures 2. 3. and 4. illustrating part sectional elevations of
these.
The stopper 10.-which is an improvement upon my previous Patents Nos. 14755
of 1st December A.D. 1885, and 8595 of 12th June A.D. 1888-is fitted with a
piece or pieces of metal, glass, porcelain, lignum vitæ, or other suitable material 11,
which is of greater specific gravity than cork, in such a manner that the stopper at
all times floats on the liquid 12. with its greater diameter upwards, as shown in
Figure 1. by the representation of a stopper in dotted lines.
The ballast may be in the form of a cylinder, as shewn in Figures 1. and 2 ;
frustum of a cone, Figure 3, or otherwise, and is fixed to the bottom of the stopper
by a circular dovetail joint, as in Figure 2; or by being screwed into it as in
Figure 3, or by reducing the diameter of the portion which passes through the
stopper and fastening it by a nut or washer at the other side as in Figure 4.
The stopper, in its natural condition is necessarily larger than the aperture in the
neck of the vessel, and in order to get it thereinto, it is placed in hot water or .
otherwise made soft or readily compressible; and in that state is pushed into the
bottle or other vessel.
The aperture 13. in the neck of the vessel is made in two diameters, the larger of
which is towards the inside, thus forming an annular seat 14.
The stopper is made of cork and is cylindrical in shape, its length being preferably
less than its diameter.
When the bottle is charged with aërated liquid 12. the stopper is forced into the
neck thereof, the opening through such neck being contracted so as to constitute a -
seat in or against which the aforesaid stopper becomes wedged.
The advantage of employing a cylindrical cork stopper of the type as illustrated
and described is that it can be made from ordinary cylindrical corks by any person
of ordinary skill, there being no special shaping of same.
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 combination of the improved internal cork stopper 10. of a cylindrical
form with the material of a greater specific gravity than cork, such as metal, glass,
porcelain, or lignum vitæ, in order that such cork stopper will always be caused to
float upwards, and thus properly present itself towards the orifice, when the vessel
is filled with an aërated liquid, all substantially as and for the purposes hereinbefore
set forth with reference to the annexed drawings.
2. The improved cylindrical cork stopper 10. substantially as and for the purposes
set forth.
3. The construction, combination and arrangement of the various parts consisting
of the stopper 10, weight 11, and seat 14; substantially as herein described in
reference to, and shewn in the annexed drawings.
