IMPROVEMENTS IN BOTTLES FOR AERATED OR GASEOUS LIQUIDS, AND IN CLOSING OR STOPPERING THE SAME."
Year: 1878

page_text: LETTERS PATENT to William Wharldale, of Knottingley, in the County of
York, for the Invention of "IMPROVEMENTS IN BOTTLES FOR AERATED OR
GASEOUS LIQUIDS, AND IN CLOSING OR STOPPERING THE SAME."
PROVISIONAL SPECIFICATION left by the said William Wharldale at the
Office of the Commissioners of Patents on the 4th March 1878.
WILLIAM WHARLDALE, of Knottingley, in the County of York.
"IMPROVEMENTS
IN BOTTLES FOR AËRATED OR GASEOUS LIQUIDS, AND IN CLOSING OR STOPPERING
THE SAME.'
"
This Invention relates to improvements in the manufacture of bottles for con-
taining aërated or gaseous liquids, and to the provision of simple but effective means
of closing or stoppering the same; the object of the Invention being to economise
cost in the manufacture of such bottles and in the means of closing or stoppering
them.
The bottle is formed of glass, the body being made of any convenient shape, but
at the base of the neck I make a circular groove or annular enlargement, hollow
within and bulging outwards, and which serves a purpose which will be herein-
after referred to, and round the top opening or head of the neck I make externally
a narrow rim, band, or thickened part, the use of which will also be herein-after
referred to.
The improved means of stoppering or closing the bottle thus formed consists of a
kind of metallic cap, which is fitted round the top opening or head of the neck
externally so that no part thereof goes within the neck, and which is retained in
position by its under part being bent under the said thickened rim of the bottle.
Its top part is bent inwards so as to contract its mouth or opening to a little less
than the size of the mouth or opening of the bottle. Within the cap and between
its top and the top of the neck of the bottle is fixed an annular cushion or washer
of india-rubber, and the effective closure of the bottle is caused by the gaseous
pressure within the bottle forcing a ball (of glass or other suitable material, such as
Price 6d1

page_text: has previously been used for such purposes), against the washer, and preventing
any escape of the contents until the ball is forced within the bottle by external
pressure exerted by the finger, or otherwise, and when such is done the ball will
fall into the said annular groove at the base of the neck, and will allow of an
unimpeded flow of the contents.
The size of the opening of the cap prevents the ball being forced out of the
bottle.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Willian Wharldale in the Great Seal Patent Office on the 4th
September 1878.

"
This Invention, which is illustrated on the accompanying Drawings in Figures 1
and 2, relates to improvements in the manufacture of bottles for containing aërated
or gaseous liquids, and to the provision of simple but effective means of closing or
stoppering the same; the object of the Invention being to economise cost in the
manufacture of such bottles, and in the means of closing or stoppering them.
The bottle 1 is formed of glass, the body being made of any convenient shape,
but at the base of the neck I make a circular groove or annular enlargement 2,
hollow within and bulging outwards, and which serves a purpose which will be
herein-after referred to; and round the top opening or head of the neck I make
externally a narrow rim, band, or thickened part 3, the use of which will also be
herein-after referred to.
The improved means of stoppering or closing the bottle thus formed consists of a
kind of metallic cap 4, which is fitted round the top opening or head of the neck
externally, so that no part thereof goes within the neck, and which is retained in
position by its under part 5 being bent under the thickened rim 3 of the bottle;
its top part 6 is bent inwards so as to contract its mouth or opening to a little less
than the size of the mouth or opening of the bottle. Within the cap and between
its top and the top of the neck of the bottle is fixed an annular cushion or washer 7
of india-rubber, and the effective closure of the bottle is caused by the gaseous
pressure within the bottle forcing a ball 8 (of glass or other suitable material, such
as has previously been used for such purposes) against the washer, as shown in
Figure 1, and preventing any escape of the contents until the ball is forced within
the bottle by external pressure exerted by the finger, or otherwise, and when such
is done the ball will fall into the groove 2, as shown in Figure 2, and allow of an
uninterrupted flow of the contents.
The size of the opening of the cap prevents the ball being forced out of the
bottle..

page_text: Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I would remark in conclusion that I claim as my Invention, the formation of
bottles for containing aërated or gaseous liquids with an internal groove 2 and
external rim 3, and the stoppering or closure of such bottles by means of a metallic
cap 4, retained in position by the said rim, and fitted to the bottle so as to retain
and press an elastic washer 7 on and against the head thereof, and against which a
glass or other ball 8 (such as has hitherto been used) is pressed by the gaseous
pressure within the bottle, substantially as and for the purposes above described,
and as illustrated on the accompanying Drawings.
In witness whereof, I, the said Willian Wharldale, have hereunto set my
hand and seal, this Third day of September, in the year of our Lord One
thousand eight hundred and seventy-eight.
WILLIAM WHARLDALE. (L.S.)
