IMPROVEMENTS IN THE STOPPERING OF BOTTLES DESTINED TO CONTAIN AERATED AND OTHER. EFFERVESCING LIQUIDS UNDER PRESSURE
Year: 1884

page_text: We GEORGE CURR THOMPSON and ARTHUR GILL THOMPSON of Sheffield in the
County of York Manufacturers do hereby declare the nature of our said Invention
for "IMPROVEMENTS IN THE STOPPERING OF BOTTLES DESTINED TO CONTAIN
AERATED AND OTHER. EFFERVESCING LIQUIDS UNDER PRESSURE" to be as
follows:-
The object of this Invention is to provide an easy and simple means of securing
the rubber washers in the necks of bottles having internal stoppers in such way
that the stoppers may be put in after the bottles are made and so avoid the loss
consequent upon the breaking of the stoppers which have to be put in the bottles
when they are at a great heat in the process of making and at the same time
secure the rubber washer in such way as to prevent its extraction.
The mode of accomplishing these ends is by making in the neck of the bottle a
groove of about the same thickness as the rubber washer the lower seat of which
projects a little further into the neck of the bottle than does the upper by which
arrangement the aperture in the neck of the bottle below the groove is somewhat
narrower than it is above the groove.
The rubber washer is easily placed in position and rests upon the seat of the
groove already mentioned. A ring made of ductile metal by preference or of other
material the outer edge of which is made somewhat in a V shape and the external
diameter of which is such as just to allow it to pass the upper aperture in the
bottle neck is placed upon the rubber washer. This metallic ring or whatever
other substance it may be composed of is made of such material as to allow of its
enlargement under pressure. A tool which is acted upon either by a screw, lever
or other means is now inserted in the neck of the bottle and so adjusted as to
engage itself in the opening of the metallic washer or ring when by the action of
either screw or lever in this tool the ring is so enlarged as to project under the
upper flange of the groove and in doing so secures the rubber washer in its place
and so compresses it in such way as to withstand the pressure of the ball or other
stopper within.

County of York Manufacturers do hereby declare the nature of our said Invention
for "IMPROVEMENTS IN THE STOPPERING OF BOTTLES DESTINED TO CONTAIN

manner the same is to be performed, to be particularly described and ascertained &
in and by the following statement :—
The object of this Invention is to provide an easy and simple means of securing
the rubber washers in the necks of bottles having internal stoppers in such way
that the stoppers may be put in after the bottles are made and so avoid the
loss consequent upon the breaking of the stoppers which have to be put in the 1
bottles, when they are at a great: hoat: in the process of making, and at the samo
time secure the rubber washer in such. way as to prevent its extraction.
The mode of accomplishing these ends is by making in the neck of the bottle
a groove of about the same thickness as the rubber washer, the lower seat of which
projects a little further into the neck of the bottle than does the upper by which 1
arrangement the aperture in the neck of the bottle below the
groove is somewhat
narrower than it is above the groove. The rubber washor is easily placed in
position and rests upon the seat of the groove already mentioned. A ring made of
ductile metal, by preference, or of other material, the outer edge. of which is made
somewhat in a V shape and the external diameter of which is such as just to allow 2
it to pass the upper aperture in the bottle neck, is placed upon the rubber washer.
This metallic ring or whatever other substance it may be composed of is made of
such material as to allow of its enlargement under pressure. A tool which is acted
upon either by a screw, lever or other means is now inserted in the neck of the
bottle and so adjusted as to engage itself in the opening of the metallic washer or 2
ring when by the action of either screw or lever in this tool the ring is so enlarged
as to project under the upper flange of the groove and in doing so secures the
rubber washer in its place and so compresses it in such way as to withstand the
pressure of the ball or other stopper within..
Our special construction of metal ring of shape A in cross section is clearly
shown on the enlarged views Figures 1 and 2 and the application of such a ring of
actual size in the inner annular groove of a bottles neck B' is represented at
Figure 3 the metal rim A bearing upon and slightly compressing the rubber ring
or washer C against which the marble or spherical stopper D is caused to impinge
by the internal pressure of gas with which the bottle is. charged or produced by
fermentation from the liquid to enclose the contents.
The metal shaped A is as before stated made to the exact internal diameter
of the bottle neck and when it is pushed in and pressed down upon the rubber ring.
an enlarging tool of any desired form is inserted to engage with the inside of the
metal ring and then expanded which spreads or forces the outer and thinner
periphery of the metal ring into the annular groove E of the bottle neck producing
at the same time a slight compression of the rubber washer C and thereby making
it a better.closing.medium, than without that compression. The rubber washer
is also rigidly fixed in the annular groove and the metal ring A from the position
it occupies offers great resistance to the removal of the washer C at any time,
either by excessive pressure of gas from within or otherwise.
We are aware that metallic bodies have been used for the purpose of fixing the
rubber washers in the annular grooves in bottles necks but these have been either
fluted or made with flanges and with the annular grooves in the necks of bottles

page_text: of greater depths or differently made than the usual annular groove to accomodate
the metal ring or rings whereas by our Invention we fit our metal ring within an
ordinary annular groove.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed We declare that what
we claim is
The construction and use of a ring of ductile metal shaped thus in cross
section for partial insertion into inner annular grooves of bottles necks and upon
the rubber washers by an enlarging operation as and for the purposes described.
