My Invention although more especially designed for bottles containing aerated-
waters may also be employed for bottles containing wine, beer, and other liquors
and it consists of a stopper which is capable of being applied and removed with
facility and when in place is so held as to obviate all danger of its accidental escape -
and loss of the contents of the bottle.
The stopper consists of a plug having a short central portion of circular section
fitting the mouth of the bottle loosely, an enlargement or head of circular or other
form covering the lip of the bottle and a flat dovetail stem forming a sort of T piece
the enlarged end of which passes through longitudinal grooves at opposite sides
within the neck of the bottle, and when the stopper is rotated engages with a rim
or shoulder formed on the neck of the bottle. The enlarged end of the stem has
its corners preferably rounded off and the lower edge of the rim on the neck of the
bottle is also bevelled so as to facilitate the rotation of the stopper when it is
applied or removed. The central circular portion of the stopper and the under
surface of the head is covered or faced with indiarubber to seat on the mouth of the
bottle and ensure a tight closure

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said John Christian Schultz in, the Great Seal Patent Office on the
16th August 1883.
JOHN CHRISTIAN SCHULTZ of Great Tower Street in the City of London
"IMPROVEMENTS IN STOPPERING BOTTLES
"
My Invention although more especially designed for bottles containing aerated
liquids, may also be employed for bottles containing wine, beer and other liquors
or liquids generally and it consists of a stopper which is capable of being applied
and removed with facility, and when in place is positively held as to obviate all
danger of its accidental escape and consequent loss of the contents of the bottle.
The stopper which may be made of glass, earthenware, composition, wood, meta!
or other material, consists of a plug having a short central portion of circular
section fitting the mouth of the bottle loosely, an enlargoment or head of circular
or other form covering the lip of the bottle and a flat dovetail stem forming a sort
of T piece the enlarged end of which passes through longitudinal grooves or cutaway
portions at opposite sides within the neck of the bottle, and when the stopper is
rotated engages with a rim or-shoulder-formed on the inside of the neck of the
bottle.
The enlarged end of the stem has its corners preferably rounded off and the
lower-edge of the rim on the neck of the bottle is also bevilled so as to facilitate
the rotation of the stopper when it is applied or removed. The central circular
portion of the stopper and the under surface of the head is covered or faced with
indiarubber to seat on the mouth of the bottle and ensure a tight closure.
The Invention is illustrated in the accompanying drawings, Figures 1 and 2
showing the stopper in elevation, the views being at right angles to one another,
and Figure 3 an underside plan. It will be seen that the stopper consists of a short
central portion a having a dovetail stem b and a head c.
In Figure 4 the stopper is shown applied to the mouth of the bottle in the
position it would be in when in the act of stoppering the bottle or in removing the
stopper, and in Figure 5 the stopper is shown in its locked position being turned
one quarter round and its T head engaging with the rim formed on the bottle neck
at d. Figure 6 is a top view of the neck of the bottle showing the grooves or
depressions e which are formed in the neck to admit of the passage of the stem of
the stopper when being applied to or removed from the bottle.
Instead of providing the bottle with the rim d for locking the stopper in position,
the mouth of the bottle may be internally of approximately oval form, that is to
say, of the form shown in Figures 7 and 8 where the depressions e (or long axis of
the oval) extend from the upper edge or mouth of the bottle for about half an inch
down the neck where they run out flush with the neck which is of the form shown
in the drawings.
The stopper is inserted and removed as before, the form of the neck ensuring the
holding of the stopper in place when rotated one quarter so as to bring the T head
into a position at right angles to the depressions e as indicated in dotted lines in
both figures.
The central circular portion of the stem is faced with indiarubber to seat on the
mouth of the bottle and ensure a tight closure.
Having described the nature of the said Invention and the manner of performing
the same I declare that what I claim as the Invention to be protected by the
herein before in part recited Letters Patent is :-
1. A stopper for bottles provided with a flat dovetail stem or Ṭ piece adapted to

page_text: engage with the bottle whereby its withdrawal is prevented, substantially as
described.
2nd. The improved stopper for bottles consisting of a plug having a short central
portion a of circular section, an enlargement or head o covering the lip of the bottle
and a flat dovetail stem b, the enlarged end of which passes through grooves,
depressions or cut away portions in the neck of the bottle and engages with a rim
or shoulder on the neck of the bottle, substantially as shown and described.
3rd. The combination with a bottle whose neck is provided with opposite longi-
tudinal grooves or depressions on its internal surface, of a stopper or plug having
a flat dovetail or T stem adapted to lock the stopper in position substantially as
shown and described.
In witness whereof I the said John Christian Schultz have hereunto set my
hand and seal this fifteenth day of August A.D. 1883.
