PROVISIONAL SPECIFICATION.
An Improved Stopper for Bottles, Jars, and the like.
1, GERARD COLLINGWOOD Clark, of 4, Ashland Place, in the county of London,
Manufacturer, do hereby declare the nature of this invention to be as follows:—
This invention relates to improvements in that class of stoppers which are made of
a stem or body of suitable hard material such as wood, glass or porcelain, and a
covering of elastic material such as cork over that part of the stopper which fits into
the mouth of the bottle or jar to be stoppered.
In carrying out my invention I make the stem of the stopper taper in form and
with a groove near the lower end thereof. Over this taper and grooved stem I pass a
ring or cylinder of cork or other suitable elastic material which, taking into the
groove in the stem of the stopper, will be firmly held on the stopper without necessi-
tating the use of cement.

COMPLETE SPECIFICATION.
An Improved Stopper for Bottles, Jars, and the like.
I, GERARD COLLINGWOOD CLARK, of 4, Ashland Place, in the county of London,
Manufacturer, 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 :-
This invention relates to improvements in that class of stoppers which are made of
a stem or body of suitable hard material such as wood, glass or porcelain, and a
covering of elastic material such as cork over that part of the stopper which fits into
the mouth of the bottle or jar to be stoppered.
In carrying out my invention I make the stem of the stopper preferably taper in
form and with a groove near the lower end thereof. Over this taper and grooved
stem I pass a ring or cylinder of cork or other suitable elastic material which, taking
into the groove in the stem of the stopper, will be firmly held on the stopper
without necessitating the use of cement.
In order to enable my invention to be fully understood I will describe how it can
be carried into practice by reference to the accompanying drawing, in which
Figure 1 is an elevation, and
Figure 2 a vertical section of a bottle stopper made according to my invention, and
Figure 3 is a section of the stem of the stopper without the covering of elastic
material.
In the drawing, a is the stem of the stopper made of wood, glass, porcelain or other
suitable hard material and taper in form as shewn (but it may be made straight); bis
the groove near the lower end of the stem a, and c is the cylinder of cork or other
suitable elastic material which is passed or sprung over the taper stem a so that the
lower portion of the cylinder c will take into the groove 6 as clearly shewn in
Figure 2, whereby the elastic cylinder will be firmly held on the stem a without
necessitating the use of cement.
In some cases the lower end d of the stem a of the stopper may be made of larger
diameter than the diameter of the lower taper part of the stem, whereby all risk of
the cylinder sliding off the stem would be avoided.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
.
1. A stopper for bottles, jars and the like having a tapered or straight and grooved
stem over which is passed or sprung a ring or cylinder of suitable elastic material
substantially as hereinbefore described.
2. The manufacture and use of the improved stopper hereinbefore described and
illustrated in the accompanying drawings.
