AN IMPROVED BOTTLE STOPPER
Year: 1885

page_text: I JOHN CHRISTIAN SCHULTZ of 1 Laurence Pountney Hill in the City of
London, Wine Merchant do hereby declare the nature of the said invention for
"AN IMPROVED BOTTLE STOPPER," to be as follows:--
My Invention relates to an internal stopper for bottles which is more especially
adapted to replace the ordinary cork or other stopper when a portion of the
contents of a bottle has been removed. The stopper consists of a cylindrical stem
made in two different diameters carrying an indiarubber ring or washer and
having at one end a head and at the other a rim or projection to prevent the
ring from coming off.
To insert the stopper in the bottle the ring is placed on the smaller diameter of
the stem and pressure applied so as to force the stopper in, whereupon the ring is
rolled over along the stem and expanded onto the larger diameter of the stem
until it occupies a position beneath the head of the stopper. The upper part or
larger diameter of the stem is preferably coned and has an enlargement which fits
the mouth of the bottle and against which the ring or washer comes when in
position.

page_text: I JOHN CHRISTIAN SCHULTZ of 1-Lawrence Pountney Hill in the City of
London, Wine Merchant, 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 :-
My invention relates to a stopper for bottles especially adapted to replace the
cork or other stopper when a portion of the contents of a bottle has been removed.
The stopper consists of a cylindrical stem or plug made in different diameters at
"different points in its length so as to form a shoulder on the stem which carries an
india rubber. ring or washer and has at one end a head and at the other a rim or
projection to prevent the ring. from coming off.
The ring is of such size as to be capable of just passing into the bottle mouth
when on the smaller diameter of the stem and the upper portion of the stem is of
such diameter as to jamb the ring in the mouth of the bottle and form a tight
closure when the stopper is applied to the bottle.
To insert the stopper in the bottle the ring is placed on the smaller diameter of
the stem just beneath the shoulder and pressure applied so as to force the stopper
in against the resistance caused by the ring coming against the shoulder where-
upon the ring is rolled over itself along the stem onto the larger diameter of the
stem until it occupies a position in the narrowest part of the bottle neck causing a
perfectly air tight closure. The upper part or larger diameter of the stem is
preferably of conical form and has an enlargement which fits the mouth of the
bottle.
By taking hold of the head, the stopper can be easily pulled out, the ring rolling
back on the stem towards the smaller diameter.
The stopper is shown in the accompanying drawings.
Figure 1 is a section of the neck of a bottle with the stopper in place. In figure 2
the stopper is shown as having been just withdrawn from, or about to be inserted
in the bottle, while figure 3 is a longitudinal section of the stopper.
The said stopper is made in two cylindrical portions a a', of which the upper
portion a¹ is preferably conical, with a head band a rim b¹.
c is the ring or washer of india rubber or equivalent material adapted to roll
over and pass from either of the cylindrical portions a a¹ constituting the stem to
the other in the act of inserting or withdrawing the stopper. d is an enlargement
beneath the head b fitting in the mouth of the bottle when the stopper is in place.
To insert the stopper the ring c is placed in the position shewn in figure 2 and
the stopper is then forced into the bottle and in the act of doing this the washer c
is caused to roll along the stem a¹ until it occupies the position shewn in figure 1
the expansion of the ring then effectually closing the bottle. To withdraw the
stopper it is simply necessary to pull it out by the head the washer rolling back
to its original position on the lower part a of the stem.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that
what I claim is
A bottle stopper consisting in the combination with a stem of different
diameters at different parts of its length as herein shown and described, of an
india rubber ring or washer adapted to roll upon the stem and form a closure for
the bottle mouth substantially as specified.
