Improvements in Stoppering Bottles.
¡e, GEORGE ALFRED LEIGHTON, of No. 1 Kings Road, St. Leonards, Sussex,
d CHARLES BALL, of Monte Rosa, St. Leonards, Sussex, Engineers do
ereby declare the nature of the said invention to be as follows:-
This invention has for its object the stoppering of bottles of all kinds principally
those used in the heer and mineral water trades.
Its main features are that there is no contact between the liquor and any india
rubber ring or adjustment, that no dust can accumulate in the neck of the bottle,
that it does away with the danger of bursting of the bottles, and that no part of
the stoppering is wasted and therefore can be used over and over again.
To obtain this result we cause a thread to be raised on the exterior of the neck
of the bottle either during the moulding of the glass hottle; or if it is desired to.
use a metal thread, the neck of the bottle has a depressed ring outside, and we run
a little easily melting metal or alloy into this ring while the bottle is held head
downwards into a small mould containing a thread.
The bottle thus contains a little threaded ring of metal which cannot slip away,
being contained in the annular depression before mentioned, formed in the bottle
while it is being moulded.
The second portion or movable part of the stoppering is formed by a cap either
of metal, hardware, wood, glass, or any other suitable material, containing in
its inside a thread corresponding with a very easy fit to the thread formed outside
the head of the bottle. This cap contains either a disc of india rubber covered
by a smaller disc of cork or other suitable material, or preferably simply only a
disc of cork of sufficient thickness to give the necessary elasticity.
The top of the cap is formed with a rounded central protuberance which tends
to push the cork disc more tightly into the neck of the bottle, thereby making
a better joint than if the cork was simply pressed evenly and flatly against the
top of the bottle.
The bottle is preferably made with a slight shoulder of the same diameter as the
outside of the cap where the cap arrives when it has been screwed down tight,
thereby giving a neat and even appearance to the outside of the bottle.

We, GEORGE ALFRED LEIGHTON of No. 1 Kings Road, St. Leonards, Sussex,
and CHARLES BALL, of Monte Rosa, St. Leonards, Sussex, Engineers, 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 has for its object, the stoppering of bottles of all kinds principally

page_text: those used in the beer and mineral water trades. Its main features arc t
is no contact between the liquor and any india rubber ring or adjustment,
dust can accumulate in the neck of the bottle, that it does away with the dat
bursting of the bottles, and that no part of the stoppering is wasted, and ther.
can be used over and over again.
To obtain this result, we cause a thread A, as shown at Figure 1 of the ann
drawings, to be raised on the exterior of the neck B of the bottle C either dur
the moulding of the glass bottle, or if it is desired to use a metal thread, the
of the bottle has a depressed ring D, Figure 2, outside, and we run a little ea
melting metal or alloy into this ring while the bottle is held head downwards iL
a small mould containing a thread.
The bottle thus has affixed to it a little threaded ring of metal E which cannc
slip away being contained in the annular depression D, before mentioned, formed
in the bottle while it is being moulded.
The second portion or movable part of the stoppering is formed by a cap F
either of metal, hardware, wood, glass, or any other suitable material containing in
its inside thread corresponding with a very easy fit to the thread formed outside
the head of the bottle. This cap F contains either a disc of india rubber G
covered by a smaller disc of cork H, or other suitable material, as at Figure 1,
or preferably simply only a disc of cork of sufficient thickness to give the necessary
elasticity, as at Figure 2.
The interior top of the cap F is formed with a rounded central protuberance I
which tends to push the cork disc H more tightly into the neck of the bottle
thereby making a better joint than if the cork was simply pressed evenly and flatly
against the top of the bottle.
The bottle is preferably made with a slight shoulder J of the same diameter as
the bottom edge of the cap F where the cap arrives when it has been screwed
down tight, thereby giving a neat and even appearance to the outside of the
bottle.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed we declare that what we
claim is :-
In combination and for use with a threaded necked bottle, a threaded
cap having
an internal protuberance for allowing the cork disc to fit slightly within and to bea
upon the top edge of the neck, whether said cork disc be backed up with rubber o
employed alone, as set forth and as shown in the annexed drawings.
