PROVISIONAL SPECIFICATION.
Improvements in or relating to the Stoppering of Bottles and
the like.
I, HENRY HEARTFIELD, of Croydon, in the County of Surrey, Mineral Water
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the stoppering or corking of bottles and similar vessels
and has particular reference to means for preventing the cork from being forced out
by internal pressure.
In carrying out the invention I prefer to form the neck of the bottle or other
vessel in the manner set forth in my Specification No. 8871 of 1889 in which a
ledge or equivalent groove or projection is provided upon the interior of the neck.
The stopper may be an ordinary cork or made of other suitable and preferably
elastic material, and provided with a projection adapted to engage with the before
mentioned ledge or groove so as to retain the cork when once inserted. Various
means may be adopted for providing the projection upon the cork or equivalent,
and when what I may call an artificial cork, or one specially manufactured is made,
the projection may be formed in the process of manufacture in any desired manner.
In dealing with an ordinary cork I prefer to force a small peg or slip of wood or
other suitable material into the side of the cork in the direction in which its inner
end would be directed towards the interior of the vessel; this direction is preferred
because the peg then readily yields when the cork is inserted into the bottle and
also readily springs out again as soon as it has passed the ledge and thus prevents
the return of the cork.
Where the bottle neck is formed with a simple ledge extending partially around
the interior of bottle neck all that is necessary for withdrawing the cork is to turn
it by any suitable means say a pronged instrument, a suitable corkscrew or the like
and when the peg or projection is clear of the ledge the cork can be withdrawn.
Where the groove in the neck is made as a screw thread the cork may be with-
drawn with one of the instruments previously described by merely turning it round
the projection engaging with the screw thread and thus drawing the cork out.
More than one projection may be employed upon the cork or equivalent or the
whole cork and neck may be formed as interrupted screw threads as is commonly
used with the breach plug of a gun.

COMPLETE SPECIFICATION.
Improvements in or relating to the Stoppering of Bottles and
the like.
I, HENRY HEARTFIELD, of Croydon, the County of Surrey, Mineral Water
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 the stoppering or corking of bottles and similar vessels
and has particular reference to means for preventing the cork from being forced
out by internal pressure.
It consists essentially in constructing the cork or stopper with a projection or
projecting peg to fit under a screw thread or ledge in the neck of the bottle or jar
to hold it securely in position so that by turning the cork or stopper it may be
readily withdrawn.

page_text: It will be fully described with reference to the accompanying drawings.

improved cork in position.
Fig. 2. Sectional elevation of cork.
Fig. 3. Sectional elevation of bottle neck formed with a groove in the neck.
Fig. 4. Elevation of modified form of cork.
Fig. 5. Section of same.
Fig. 6. Section of another modification.
I prefer to form the neck of the bottle or other vessel in the manner set forth in
my Specification No. 8871 of 1889 in which a thread or ledge or equivalent groove
or projection is provided upon the interior of the neck. The stopper A may be an
ordinary cork or made of other suitable and preferably elastic material, and
provided with a projection a adapted to engage with the before mentioned ledge or
groove so as to retain the cork when once inserted.
Various means may be
adopted for providing the projection a upon the cork or stopper A, and when what
1 may call an artificial cork, or one specially manufactured is made, the projection
may be formed in the process of manufacture in any desired manner.
In dealing with an ordinary cork I prefer to force a small peg or slip of wood a
or other suitable material into the side of the cork in the direction in which its
inner end would be directed towards the interior of the vessel; this direction is
preferred because the peg then readily yields when the cork is inserted into the
bottle and also readily springs out again as soon as it has passed the ledge and thus
prevents the return of the cork.
The peg a may be in the form of short pieces of wood or other suitable material
inserted in one two or more sides of the cork as in Figs. 1, 2 and 3 or it may be in
the form of a curved metal strip or peg passed through the cork as in Figs. 4 and 5
or it may in the case of a stopper made of vulcanite, rubber or other similar material
be formed as part thereof as in Fig. 6.
The sides of the cork or stopper A may also be coated with paraffin wax or
other suitable material which will facilitate the driving in and withdrawing of it
and render it impervious to moisture and prevent leakage from a faulty cork.
Where the bottle neck is formed with a simple ledge as in Fig. 3 extending
partially around the interior of the bottle neck all that is necessary for withdrawing
the cork is to turn it by any suitable means say a pronged instrument, a suitable
corkscrew or the like and when the peg or projection is clear of the ledge the cork
can be withdrawn.
Where the groove in the neck is made as a screw thread as in Fig. 1 the cork
may be withdrawn with one of the instruments previously described by merely
turning it round the projection engaging with the screw thread and thus drawing
the cork out.
More than one projection may be employed upon the cork or equivalent or the
whole cork and neck may be formed as interrupted screw threads as is commonly
used with the breach plug of a gun.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A cork or stopper for bottles provided with a projection or peg projecting
from one or both sides to fit into a screw thread or groove or under a ledge in the
bottle neck to secure the cork in position substantially as described and shown.
2. The combination with a cork or stopper for bottles of one or more pegs a
inserted in the cork or stopper and projecting from the sides thereof substantially
as described and shown more particularly with reference to Figs. 2 and 5.
