Contractor do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the class of stoppers described in
the Specification of my former Letters Patent dated December 15th A.D. 1880
No 5264. In such specification I have described and shewn a conical stopper
which is forced and subsequently drawn (by ineans of a hook passed through a
hole in the said stopper) firmly into contact with a ring of cork retained in å
groove in the neck of the bottle.
I have found however that when such stopper is made conical it in frequent
cases can be drawn completely through the ring of cork and thus render the bottle
useless. It is the object of my present invention to, obviate this and for this
purpose I form the stopper somewhat bell-shaped in configuration that is to say
the exterior of such stopper is concave so that when it is drawn into contact with
the cork ring it will form for itself at its enlarged lower end a seat within such ring
and cannot be withdrawn. I also provide the stopper with a flattened top having
a hole in it for the passage of the hook as heretofore and in order to prevent the
cork ring being cut by the sharp corners at each side of such flattened part as in
the prior stopper I form the portion of the stopper at each side of such flattened
part inclined.

Contractor 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 reference being had to the accompanying drawing forming
a part of this specification :-
My invention, relates to improvements in the class of bottle stoppers described in
the Specification of my former Letters Patent dated December 15th A.D. 1880
No 5264. In such specification I have shewn and described a conical stopper
which is forced and subsequently drawn (by means of a hook passed through a
hole in the said stopper) firmly into contact with a ring of cork retained in a
groove in the neck of the bottle.
I have found however that when such stopper is made conical it in frequent
cases can be drawn completely through the ring of cork and thus render the bottle
useless. It is the object of my present invention to obviate this and for this
purpose I form the stopper as shewn in the drawing in which
Figure 1 is a vertical section of a bottle with my improved stopper in position
therein and
Figure 2 is an exterior view of the said stopper detached looking in a direction
at right angles to the plane of the section in Figure 1.
Like letters indicate the same parts in both Figures.
a represents the bottle b, the cork ring and c the stopper. This stopper is some-
what bell-shaped in configuration that is to say the portion c¹ of such stopper is
made concave as shewn so that when it is drawn into contact with the cork ring b
it, will form for itself at its enlarged lower end a seat within such ring and cannot
be withdrawn. I also provide the stopper with a flattened top as at c³ having a
hole in it for the passage of the hook as heretofore and in order to prevent the
cork ring from being cut by sharp corners at each side of such flattened part as in
my former stopper I form the portion of the stopper at each side of such flattened
part either rounded or inclined as at c*.
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
A bottle stopper constructed substantially as herein set forth for the purpose
specified.
