I GEORGE FREDERICK REDFERN, of the General Patent Office, N° 4 South Street,
Finsbury, in the county of Middlesex, Patent Agent do hereby declare the nature
of this invention (a communication from abroad by C. Korthaus of Cologne-on-the-
Rhine, in the Empire of Germany) to be as follows :-
This invention relates to the construction of an improved device or stopper for
closing bottles, jars and other vessels whereby the necessity of using a fresh cork
each time the vessel is closed or stoppered is dispensed with and allowing of the
latter being easily opened without any special tool being required for this purpose
so that bottles containing effervescing beverages under pressure can be easily
emptied of their contents while at the same time the stopper can be re-used.
For this purpose the device or stopper is constructed of a metallic cap which is
fixed to the mouth of the bottle or other vessel either by means of a screw thread,
a'bayonet joint or other suitable means. This cap is provided centrally with a
tubular projection, upon which is placed a ring of india rubber or other suitable
elastic inaterial. The said tubular projection is curved or bent outwards at the
lower end by means of a mandril. or otherwise so as to compress the elastic ring
between the inner surface of the mouth of the bottle or other vessel and the said
tubular projection. Within the tubular projection, after the bottle or other vessel
has been filled, a small cork is placed which serves to close the same and to assist
in compressing the elastic ring, the cork extends past the end of the said tubular
projection where it 'expands and thereby entirely separates the india-rubber and
the metal from the contents of the bottle or other vessel.

I GEORGE FREDERICK REDFERN of the General Patent Office, N° 4, South Street,
Finsbury, in the county of Middlesex, Patent Agent do hereby declare the nature
of this invention (a communication from abroad by C. Korthaus of Cologne-on-the-
Rhine in the Empire of Germany) 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 the construction of an improved device or stopper for
closing bottles, jars and other vessels whereby the necessity of using a fresh cork
each time the vessel is closed or stoppered is dispensed with and the latter can be
easily opened without any special tool being required for this purpose so that
bottles containing effervescing beverages under pressure can be easily emptied of
their contents while at the same time the stopper can be re-used.
In order to enable the invention to be fully understood I will describe the same
by reference to the accompanying drawing the several figures of which represent a
closing device or stopper applied to a bottle neck in the various stages of
construction according to this invention. Similar letters in all the figures represent
similar parts.
The device or stopper is constructed of a metallic cap a, which is fixed to the
mouth of the bottle or other vessel either by means of a screw thread as shewn in
figures II III and IV a bayonet joint as shewn in figure I or by other suitable
means. This cap is provided centrally with a tubular projection as shewn at b,
figures I and II upon which is placed a ring of india-rubber or other suitable
elastic material. The said tubular projection is curved or bent outwards at the
lower end by means of a mandrel or otherwise so as to cause it to assume the
shape shewn in figure III whereby the elastic ring is compressed between the inner
surface of the mouth of the bottle and the tubular projection b. Within the
tubular projection b, after the bottle has been filled, a small cork d, is placed as
shewn in figure IV which cork serves to close the tube and to assist in compressing
the elastic ring c; the cork d, extends past the end of the said tubular projection
where it expands and thereby entirely separates the india-rubber c, and the metal
from the contents of the bottle as shewn in figure IV.
Having now particularly described and ascertained, the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
A device or stopper for closing bottles, jars and other vessels, consisting of a
metallic cap provided with a central tubular projection b, which extends into the
mouth of the bottle the said cap being surrounded by a ring c, of elastic material
and provided with a cork d, placed in the said tubular projection b, substantially as
berein before described and represented in the accompanying drawing.
Dated this 14th day of May 1886.
