IMPROVEMENTS IN STOPPERS FOR AERATED WATER BOTTLES."
Year: 1881

page_text: LETTERS PATENT to Joseph Massey, of 27, Atlas Terrace, Kirkwhite Street,
Nottingham, for an Invention of "IMPROVEMENTS IN STOPPERS FOR AERATED
WATER BOTTLES."
PROVISIONAL SPECIFICATION left by the said Joseph Massey at the Office
of the Commissioners of Patents on the 16th June 1881.
JOSEPH MASSEY, of 27, Atlas Terrace, Kirkwhite Street, Nottingham, “IMPROVE-
MENTS IN STOPPERS FOR AERATED WATER BOTTLES."
This Invention relates to stoppers for closing the mouths or necks of bottles, the
object being to so form a stopper that it can effectually close the mouth of a bottle,
and also be easily dislodged for opening it, the stopper itself being kept in its place
in the bottle neck by the pressure of the gas, such as is usually present in bottles
containing soda and other similar waters.
The Invention consists in forming a stopper consisting of a core or centre made
of earthenware, glass, or other suitable material, surrounded in the central
portion of its length by a short cylinder of india rubber or similar elastic
material.
The core or centre is slightly reduced in diameter at a short distance from each
end, so that small shoulders are formed which serve to secure the cylinder of india
rubber when in place, whilst the central portion of its length is still further reduced
so as to form an annular recess at that part.
The diameter of the core of the stopper is thus much greater next to the before
mentioned shoulders than it is at the annular recess, so that when the rubber is in
its place the ends of the rubber cylinder firmly grip the larger diameter of the
reduced portion of the core next the shoulders, whilst the central portion of the
core through the recess sustains little or no grip at all, which causes the rubber to
hold very effectually in its place.
The shoulders on the central core are comparatively slight in depth so that the
ends of the rubber cylinder project considerably around it, and when the stopper is
closing a bottle one of these ends (the stopper being double ended) is made to bear
tightly against a shoulder on and within the neck of the bottle, against which it is
firmly pressed by means of the gas within it.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Joseph Massey in the Great Seal Patent Office on the 28th November
1881.
JOSEPH MASSEY, of 27, Atlas Terrace, Kirkwhite Street, Nottingham. "IMPROVE-
MENTS IN STOPPERS FOR AERATED WATER BOTTLES,"
This Invention relates to stoppers for closing the mouths or necks of bottles, the
object being to so form a stopper that it can effectually close the mouth of a bottle,
and also be easily dislodged for opening it, the stopper itself being kept in its place
in the bottle neck by the pressure of the gas such as is usually present in bottles
containing soda and other similar waters.
The Invention consists in forming a stopper of a core or centre made of earthen-
ware, glass, or other suitable material, surrounded in the central portion of its
length by a short cylinder of india rubber or similar elastic material.
The core or centre is slightly reduced in diameter at a short distance from each
end so that small shoulders are formed which serve to secure the cylinder of india
rubber in place, whilst the central portion of its length is still further reduced so as
to form an annular recess at that part. The diameter of the core of the stopper is
thus much greater next to the before mentioned shoulders than it is at the annular
recess, so that when the rubber is in its place the ends of the rubber cylinder
firmly grip the larger diameter of the reduced portion of the core next the shoulders
whilst the central portion of the core through the recess sustains little or no grip,
which causes the rubber to hold very effectually in its place.
The shoulders on the central core are comparatively slight in depth so that the
ends of the rubber,cylinder. project considerably around it, and when the stopper is
closing a bottle one of these ends (the stopper being double ended) is made to bear
tightly against a shoulder on and within the neck of the bottle, against which it is
firmly pressed by means of the gas within it.
My Invention is clearly shown at Figures 1, 2, and 3 of the annexed Drawings.
Both ends A, B, of the stopper are alike, and their inner surfaces form shoulders
at C, D, for the rubber cylinder E to rest and abut against to resist it coming
from the stopper under the pressure of gas. The parts F, G, of the stopper are
reduced in diameter to the centre or mid-distance at H, into which the rubber
lodges itself, and follows the contour at that part as shown at Figure 2; Figure 3
shows the stopper in position in a bottle I.
: I am aware that conical shaped internal stoppers for gaseous liquid bottles have
been used long before the date of my Letters Patent, but theso cones have been in
the reverse position to mine, so that the bellied portion of the rubber comes into
contact with the bottle to close the mouth. I therefore make no claim to a conical
shaped internal stopper, nor do I claim the employment of a rubber cylinder as a
closing medium for such bottles, but what I do claim is,―
The plug A, B, having the reduced, diminished, or concaved central portion F,
G, H, as in Figure 1, in which a rubber cylinder E can lodge itself as in Figure 2,
and the closing of the bottle's mouth be effected by contact with the shoulder J
of the bottle's neck, as in Figure 3, by the internal force of gas within said bottle,
as described.
In witness whereof, I, the said Joseph Massey, have hereunto set my hand
and seal, this Twenty sixth day of November, in the year of our Lord
