Improvements in Stoppering Bottles, Jars, or other Vessels.
We, ALFRED WILLIAM BIRT of the Marine Life Saving Apparatus
Manufactory, Tower Works Wapping, London, E. Manufacturer and JOHN
LOWMAN of 78 Coburg Road, Old Kent Road London, S.E. Cork Cutter do
hereby declare the nature of this invention to be as follows:-
This invention relates to stoppering bottles jars or other vessels and the object
of the said invention is to provide in a simple and economic manner a tight joint
and packing so that the liquid in the bottle et cetera can only come in contact with
the underside of the stopper itself (which may advantageously be of glass or
porcelain) and the packing which is advantageously cork thus avoiding con-
tamination or deterioration of the liquid so frequently caused by other stoppers
such as those having india rubber packing.
Now according to the present invention we proceed as follows:-
A female screw thread of a suitable pitch or depth is formed internally in the
neck of the bottle (&c.) which is slightly tapered outwards towards the top.
The stopper has a corresponding male screw thread thereon and is slightly
tapered also to correspond with the taper in the neck of the bottle et cetera but is
of a smaller size in diameter than the diameter of the said internal female screw so
as to permit of a ring or strip of cork or other suitable packing (but advantageously
cork) being interposed between the male and female screw threads.
Upon screwing down the stopper the ring or strip of cork (et cetera) is tightly
wedged in between the male and female screw threads and thus forms a tight packing
the cork (et cetera) being forced into the threads and assuming a thread itself on
both faces thereof.

COMPLETE SPECIFICATION.
Improvements in Stoppering Bottles, Jars, or other Vessels.
We, ALFRED WILLIAM BIRT of the Tower Works, Wapping, London, E.
Cork Merchant, and JOHN LOWMAN of 78, Coburg Road, Old Kent Road,
London, S.E. Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in stoppering bottles jars and other
vessels or receptacles of glass, china, porcelain, wood, metal or of any other suitable
material.
Our invention consists essentially in introducing a tapered strip or lining of cork
or other suitable material as a packing between the screw thread or "male" thread
on the stopper and the internal thread or female thread formed in the neck or
opening in the bottle jar or other vessel (this packing being advantageously of cork
for many reasons) and both the said threads being tapered-as will hereinafter be
described and finally pointed out in the claims.
For the sake of brevity we will describe the said lining or packing as of cork
but we wish it to be distinctly understood that other suitable material may
י

page_text: And in order that our present invention may be fully and easily understood
we will proceed to describe our said invention with reference to the drawings
hereunto annexed.
Figure 1 represents-in side elevation partly in section—the stopper a in position
in the neck of a bottle jar et cetera,
Figure 2 is a side elevation of the stepper a separate from b..
Figure 3 is a side sectional elevation of the neck of the bottle etc. having the
cork washer lining or ring of cork c therein.
Figure 4 is a plan or edge view of the cork lining or circle of cork before
insertion in the neck of the bottle et cetera.
Figure 5 is a side elevation of Figure 4-that is Fig. 5 is a view of the ring of
cork c separate from the bottle.
The male thread part d on the stopper a is of a smaller diameter than the female
thread in the neck so that sufficient space is left between d and (both of which
are tapered) for the introduction of the thin strip of cork e which is also tapered
and is first inserted in the neck band the stopper a is then screwed down tightly
thus compressing the cork between the thread and the thread in the side wall
of the neck band making a perfectly sound and tight joint.
G
The tapered ring of cork or cork lining is made by cutting off strips of cork
of the width and thickness desired and then these strips are bent round in a circle
and the ends thereof (which are advantageously bevelled) are joined together in any
suitable manner.
C
When the stopper a is unscrewed and removed from the neck the lining will
not come away therewith or be disturbed but will remain of itself in the neck
ready for the stopper to be re-inserted-the tapered thread d of the stopper a forcing
the cork into the thread f of the neck b.
If desired the stopper may be arranged vice versa that is to say the loose
stopper may be a cap screw threaded and tapered internally and the neck of the
bottle screw threaded externally and tapered externally also and our tapered cork
lining placed between the two threads to act in a similar manner as before
described.
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 :-
In stoppering bottles jars or other vessels or receptacles stoppered by means of a
screw stopper, the combination with a tapered screw stopper such as a and a
female screw thread f (formed internally in the tapered neck b-or vice versa) of
a tapered lining strip or ring of cork or other suitable material such as e inserted
therein between substantially in the manner and for the purposes herein before
described and illustrated in the drawings hereunto annexed.
