Improvements relating to the Stoppering or Bottles, Jars, anu
other Vessels.
I, ALFRED KEMPSON, of No. 11, Clements Lane, in the City of London, Merchant
do hereby declare the nature of this invention to be as follows:--
My invention relates to the stoppering of bottles, jars or other vessels, and has
for its chief objects to provide improved means for holding the cork or stopper against
its seat in or upon the neck of the bottle or other vessel.
According to my said invention I provide a bail or its equivalent which is suitably
pivoted near the mouth of the bottle or other vessel, so that it can be thrown over so
as not to obstruct the opening of the bottle or the like.
This bail carries a screw-threaded rod which is adapted to enter a screw-threaded
opening in the centre of the stopper proper, or of a presser adapted to bear upon
the stopper, so that when the said stopper or presser and screw rod are moved relatively
to each other the stopper either directly or through the medium of the presser will be
forced against its seat and vice-versa.
The screw rod is in all cases prevented from moving in a longitudinal direction
relatively to the bail, but it may or may not have a rotary motion. In the former
case the stopper or presser is moved longitudinally by the rotation of the screw rod,
while in the latter case the stopper or presser is rotated upon the screw.
In order to allow the stopper sufficient movement in a longitudinal direction
relatively to the screw rod and to avoid the necessity of using a stopper or presser
of unnecessary thickness, I sometimes form the same with a central protuberance
into which the screw-threaded hole extends.

Improvements relating to the Stoppering of Bottles, Jars, and
other Vessels.
I, ALFRED KEMPSON of 11 Clements Lane in the City of London, 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 the stoppering of bottles, jars or other vessels and has for
its chief object to provide improved means for holding the cork or stopper against
its seat in or upon the neck of the bottle or other vessel.
According to my said invention I provide a bail or its equivalent which is suitably
pivoted near the mouth of the bottle or other vessel, so that it can be thrown over so
as not to obstruct the opening of the bottle or the like.
This bail carries a screw threaded rod which is adapted to enter a screw threaded
opening in the centre of the stopper proper, or of a presser adapted to bear upon
the stopper, so that, when the said stopper or presser and screw rod are moved
relatively to each other, the stopper, either directly or through the medium of the
presser, will be forced against its seat, and vice-versa.
The screw rod is in all cases prevented from moving in a longitudinal direction
relatively to the bail, but it may or may not have a rotary motion. In the former
case the stopper or presser is moved longitudinally by the rotation of the screw rod,
while in the latter case the stopper or presser is rotated upon the screw.
In order to allow the stopper sufficient movement in a longitudinal direction
relatively to the screw rod, and to avoid the necessity of using a stopper or presser
of unnecessary thickness, I sometimes form the same with a central protuberance
into which the screw threaded hole extends.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawing in which
Figure 1 is a sectional view of a bottle neck having my improvements applied
thereto, the stopper being adapted to fit into the neck, and
Figure 2 is a section on the line a, a Figure 1.
Figure 3 is a sectional view showing the stopper adapted to a jar, and arranged to
bear upon the edge of the neck, and
Figure 4 is a similar view illustrating a modification.
Similar letter of reference indicate corresponding parts in the several figures.
a is the bottle neck, and b is the bail which has its ends c, c bent as shown in the
drawing, so as to enter the recesses d, d in the neck.
e is the screw or screw threaded rod which, as shown in Figures 1, 2 and 3,
has the bail threaded through it, and f is the cork or stopper which has formed in it
a screw threaded opening adapted to receive the screw e.
It will be noticed that the stopper shown in Figures 1 and 2 is, at that portion
adapted to enter the neck, provided with a ring g of cork, while the stopper shown

page_text: in Figure 3 has a packing ring h of cork or other material arranged between it
and the bottle neck.
In closing a bottle provided with my improvements the bail is raised so that the
stopper can be placed over the bottle mouth, and then the said stopper is turned so
that it moves in a longitudinal direction relatively to the screw, whereby it is finally
forced into or against its seat. In opening a bottle, the stopper is turned in the
reverse direction to withdraw or remove it from the bottle, and then thrown back
as indicated by dotted lines in Figure 2.
In the modification of my invention shown in Figure 4, the construction is
substantially the same as that herein before described, except that instead of rotating
the stopper relatively to the screw, the latter is rotated relatively to the stopper. In
this case the bail is flattened at 6', a hole being formed in this flattened part, through
which the screw passes.
A head is formed upon the screw to facilitate the operation
of the same.
I wish it understood that I do not limit my invention to use with any particular
construction of stopper, as it is obvious that the same may be varied according to
requirements.
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 other vessels, having a screw threaded opening
into which a screw, carried by a bail, adapted to enter, the said screw being so
arranged that it is incapable of longitudinal movement relatively to the bail,
substantially as, and for the purpose described.
(2) A stopper for bottles, jars and other vessels, arranged in combination with a
bail and a screw carried by the said bail in such a inanner that, when the stopper is
rotated, it will be caused to move longitudinally relatively to the screw, substantially
as described with reference to Figures 1, 2, and 3 of the drawing.
(3) The modification of my invention wherein the screw is rotated relatively
to the stopper, substantially as described with reference to Figure 4 of the drawing.
(4) The improvements relating to the stoppering of bottles, jars and other vessels,
substantially as hereinbefore described and illustrated in the accompanying drawing.
