PROVISIONAL SPECIFICATION.
Improvements in Bottles and Stoppers for Containing Aërated and
other Liquids.
We, HENRY HEARTFIELD, Foreman of Mineral Water Works, of 42 Pitlake,
Croydon, and WILLIAM GEORGE WALKER, of 83 Upper Thames Street, Secretary to
E. Breffit & Co. Ld., Bottle Manufacturers, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in bottles and stoppers for containing
aërated and other liquids, such as are described in the specifications of Letters
Patent No. 12159 dated the 8th day of September 1887 and granted to Henry
Heartfield.
For this purpose we so form the screw thread (known as the buttress screw thread)
in the neck of the bottle that it ends in an abutment at the lower termination of the
screw thread by being carried forward and gradually diminishing until it blends
with the interior of the bottle neck in the manner usually adopted when forming a
screw thread in the neck of a bottle.
By this means when the bottle is filled with still liquids air is prevented from
entering and when filled with aërated liquids the gas is prevented from escaping by
following round the recesses of the screw thread as otherwise happens when the
stopper consists of a cork or other stopper of elastic material driven in and allowed
to expand and mould itself into the screw thread formed to receive it.
To form the screw stopper we take a stopper of cork or other elastic material and
in the usual way drive it into a bottle provided with a screw thread as herein before
described and allow it to remain in the bottle neck until it is moulded to its shape.
When withdrawn it has practically become a screw stopper and can be easily
reinserted into the neck of the bottle in the same manner as an ordinary screw
stopper.
In order to provide better means of unscrewing and reinserting a screw stopper
formed in the manner described, we mount the stopper with a metal cap which is
secured to the stopper by means of a number of non continuous portions of a buttress
screw thread.
These non continuous portions of the screw thread take the form of ratchet teeth
around the inside of the metal cap. When rotating the cap to the left these ratchet
teeth obtain a firm hold upon the stopper and thereby withdraw it from the bottle;
but when the rotation is to the right, for the purpose of reinserting the stopper in the
bottle, the shoulders of these non continuous portions of a screw thread force the top
of the stopper against the inside top of the metal cap thereby becoming firm in that
direction. These same shoulders also prevent the metal cap from being removed from
the stopper in a direct manner unless a very great amount of force is employed.
Instead of employing the non continuous portions of a buttress screw thread other
forms of indentation of the metallic cap may be adopted causing portions of the
metallic cap to penetrate into the stopper as a means of uniting the stopper and its
metallic cap.
When stoppering wide mouthed bottles such as are used for pickles, we make the
stopper of glass or other material with the improved buttress screw thread formed
upon it and by recessing a groove round the inside of the bottle neck to receive a
ring of cork or other elastic material firmly fixed in its place by using any kind of
suitable cement, the stopper can be screwed into the ring and withdrawn in the
usual way.

Improvements in Bottles and Stoppers for Containing Aërated and
other Liquids.
We HENRY HEARTFIELD of 42 Pitlake Croydon in the County of Surrey Foreman
of Mineral Water Works and WILLIAM GEORGE WALKER of 83 Upper Thames Street
in the City of London, Secretary to E. Breffit and Company Limited, Bottle Manu-
facturers 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 bottles and stoppers for containing
aërated and other liquids such as are described in the specification of Letters
Patent No. 12159 dated the 8th day of September 1887 and granted to Henry
Heartfield.
Our present improvements are illustrated by the accompanying drawings in all the
Figures of which like parts are represented by similar reference letters. Figure 1 is
a sectional elevation of a cap to be applied to the cork or stopper and the cork or
stopper moulded to the shape of the screw neck of the bottle shown in sectional
elevation. Figure 2 is an elevation of the three parts of Figure 1 brought together.
Figure 3 is a sectional plan of Figure 1 upon the line A. B. Figure 4 is a section
of Figure 1 upon the line C D. Figure 5 is an elevation and Figure 6 is a plan of
the cap illustrating the alternative plan of securing the cap upon the cork or
stopper.
We so form the screw thread E (known as the buttress screw thread) in the neck
of the bottle that it ends in an abutment at F, being the lower termination of the
screw thread, by being stopped off at right angles through the full size of the thread
instead of being carried forward and gradually diminishing until it blends with the
interior of the hottle neck in the manner usually adopted when forming a screw
thread in the neck of a bottle.
By this means when the bottle is filled with still liquids air is prevented from
entering and when filled with aërated liquids the gas prevented from escaping by.
following round the recesses of the screw thread as otherwise happens when the
stopper consists of a cork or other stopper of elastic material driven in and allowed
to expand and mould itself into the screw thread formed to receive it.
To form the screw stopper we take a stopper of cork or other, elastic material and
in the usual way drive it into a bottle provided with a screw thread as hereinbefore
described and allow it to remain in the bottle neck until it is moulded to its shape.
When withdrawn it has become practically a screw stopper as shewn at G in Figure 1
and can be easily reinserted into the neck of the bottle in the same manner as an
ordinary screw stopper.
In order to provide better means of unscrewing and reinserting a screw stopper
formed in the manner described we mount the stopper with a metal cap H which is
secured to the stopper by means of a number of non continuous portions J of a
"buttress" screw thread.
These non continuous portions of the screw thread take the form of ratchet teeth
around the inside of the metal cap H. When rotating the cap H to the left these
ratchet teeth J obtain a firm hold upon the stopper and thereby withdraw it from
the bottle; but when the rotation is to the right for the purpose of reinserting the
stopper in the bottle-the shoulders of these non continuous portions J of a screw
thread force the top of the cork or stopper G against the inside of the metal cap H
thereby becoming firm in that direction. These same shoulders also prevent the
metal cap H from being removed from the cork or stopper G in a direct manner
unless a very great amount of force be employed.
Instead of employing the non continuous portions J of a "buttress" screw thread
other forms of indentation of the metallic cap H may be adopted causing portions
of the metallic cap to penetrate into the stopper as a means of uniting the stopper

page_text: and its metallic cap. This arrangement is illustrated by Figures 5 and 6 ; the cap H
being cut along the lines K K producing the points L L which may be pressed
inwardly so as to embed themselves in the cork or stopper.
وو
When stoppering wide mouth bottles such as are used for pickles we make the
stopper of glass or other material with the improved "buttress screw thread formed
upon it and by recessing a groove round the inside of the bottle neck to receive a
ring of cork or other elastic material, firmly fixed in its place by using any kind
of suitable cement, the stopper can be screwed into the ring and withdrawn in the
usual way.
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 :-
:-
1. In screw neck bottles the formation of the screw thread known as the "buttress
screw thread, being the subject matter of Letters Patent No. 12159 of the year 1887,
terminating in a stop or abutment substantially as and for the purpose described.
2. In a cork or stopper employed to be driven into a screw neck bottle of the
description claimed in the above claim 1, the cap H united thereto by means of the
non continuous portions of a " buttress " screw thread or ratchet teeth J, or
the indenting portions L substantially as described and illustrated by the accompanying
drawings.
Dated this 28th day of February 1890.
