PROVISIONAL SPECIFICATION.
Improvements in External Stoppers for Bottles and other like
Hollow Ware.
We JOHN WILKINSON of Ardsley near Barnsley in the county of York Cashier,
and GEORGE SCOTT of Ardsley aforesaid Mechanical Engineer, do hereby declare the
nature of this invention to be as follows:-
Our present invention relates to external stoppers used for hermetically sealing the
mouths of bottles and other like hollow ware, and the objects thereof are to secure the
cork or other like substance to the stopper in such a way that the same may be easily
removed therefrom and a new or fresh piece expeditiously fitted thereto in its stead
when required; and also to fit the said cork or other like substance to the stopper
in such a way that when the same be compressed into or within the mouth of the
bottle or other like article for the purpose of the hermetically closing or sealing
thereof, it is not so liable to split or fracture or otherwise become damaged as is the
case when pressing a cork or other like substance which is fitted or attached to an
external stopper in the ordinary manner; to obtain the before described objects
therefore we form the external stopper with a countersink, indent, or pocket which
extends from the lower portion of said stopper to a suitable distance up the stem
thereof; the said countersink, indent, or pocket may be of any desired shape and may
where preferred be formed with a suitable internal serer thread, it may be larger at
the top and narrower at bottom, or vice-versa as desired, and it is formed to a suitable
size so that it will effectually grip and hold firmly the cork or other like substance
when pressed, placed, screwed, or otherwise fitted therein; and at the same time will
permit of the said cork or other like substance being expeditiously removed therefrom
when required.
We would have it understood that our herein before described improvements are
applicable to all kinds of external stoppers which are constructed or made with a
suitable stem for the purpose of pressing a piece of cork or other like material or
substance into or within the mouth of a bottle or other like article for the purpose of
hermetically sealing or closing the same.

Improvements in External Stoppers for Bottles and other like
Hollow Ware.
We, JOHN WILKINSON of Ardsley near Barnsley in the county of York Cashier,
and GEORGE SCOTT of Ardsley aforesaid Mechanical Engineer 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 :-
Our present invention relates to external stoppers used for hermetically sealing the
mouths of bottles and other like hollow ware, and the objects therof are to secure the
cork or other like substance to the stopper in such a way that the same may be easily
removed therefrom and a new or fresh piece expeditiously fitted thereto in its stead
when required, and also to fit the said cork or other like substance to the stopper in
such a way that when the same be compressed into or within the mouth of the
bottle or other like article for the purpose of the hermetically closing or sealing
thereof, it is not so liable to split or fracture or otherwise become damaged as is the
case when pressing a cork or other like substance which is fitted or attached to an
[D17

page_text: external stopper in the ordinary manner; to attain the before described objects
therefore we form the external stopper with a countersink, indent, or pocket, which
extends from the lower portion of said stopper to a suitable distance up the stem
thereof, the said countersink, indent, or pocket, may be of any desired shape, and may
where preferred be formed with a suitable internal screw thread, it may be larger at
the top and narrower at bottom or vice-versa as desired, and it is formed to a suitable
size so that it will effectually grip and hold firmly the cork or other like substance
when pressed, placed, screwed or otherwise fitted therein, and at the same time will
permit of the said cork or other like substance being expeditiously removed therefrom
when required.
We would have it understood that our herein before described improvements are
applicable to all kinds of external stoppers which are constructed or made with a
suitable stem for the purpose of pressing a piece of cork or other like material or
substance into or within the mouth of a bottle or other like article for the purpose of
hermetically sealing or closing the same.
In order that our present invention may be perfectly well understood and readily
carried into effect we will proceed to further describe the same by the aid of the
accompanying drawings in which
Fig. 1. is a sectional elevation of our improved stopper secured into the mouth of
the bottle or other like hollow article by means of an ordinary screw thread. Fig. 2.
is a sectional elevation of a modified form of our improved stopper. Fig. 3 is a
sectional elevation of our improved stopper secured to the mouth of bottle or other
like hollow article by means of an ordinary screw thread formed on outside of mouth
thereof. Fig. 4 is a sectional elevation of our improved stopper secured to the mouth
of the bottle or other hollow article by means of an ordinary bayonet joint, and
Fig. 5 is another modification of our improved stopper secured to the mouth of
bottle or other hollow article by means of an ordinary external screw thread. Like
letters of reference designate corresponding parts in each figure.
Referring to fig. 1. the stopper A is made with an ordinary stem a¹ having a
specially formed countersink, indent, or pocket a² which receives the upper portion of
the piece of cork B. The stopper A is shown with an ordinary screw-thread which
screws into the mouth of bottle C and effectually secures the cork B into said mouth
and so hermetically seals said bottle. The countersink, indent, or pocket a² may
he made as shown at figs. 1. 3. 5, or in a screw fashion as shown at fig. 2, or in
any other desired form so that the piece of cork B may be easily and expeditiously
placed therein and removed therefrom.
In fig. 3 the improved stopper A is screwed onto outside of mouth of bottle or other
like hollow article and the stem a¹ thereof with pocket, indent, or countersink a³
extends within the mouth C as shown.
Referring to fig. 4 our improved stopper A is made to suit an ordinary bayonet
formed bottle-mouth, and referring to figure 5 the improved stopper A is screwed
into mouth of bottle and the pocket, indent, or countersink a is made more shallow
so that a thinner piece of cork B may be placed therein before hermetically sealing
up the bottle or other like hollow article after the same has been charged or
filled.
By means of the stem a¹ of the stopper A figs. 1. 3. 4 and 5 being formed with
indents, countersinks, or pockets a² as shown, the stopper when pressing the piece of
cork B into the mouth of bottle does, not tear or break the same, and if the said
indent be made sufficiently taper as shown in Fig. 4 the piece of cork B would stay
within the mouth of the bottle after removing the stopper should the bottle not
contain sufficent pressure of gas to force the same out and when. such a bottle
contains beer or porter this would be the means of indicating whether the same be
flat or not.
The stoppers illustrated in the drawings exemplify several methods of embodying
our present invention in practical form but it must be distinctly understood that our
invention is not limited to the particular forms of stoppers illustrated inasmuch as
they may be varied, and they are put forward as typical illustrations rather than final

page_text: forms, that is to say the pocket, indent, or countersink may be arranged in any
form of stopper of a bottle or other like hollow article where such stopper is formed
with a stem a¹.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. The use of a stopper A having a countersink, indent, or pocket a³ formed in its
stem a¹ for the reception of a piece of cork B substantially as described and used for
the purpose set forth.
