LETTERS PATENT to Hiram Codd, of Grove Lane, Camberwell, in the County
of Surrey, Glass Bottle Manufacturer, for the Invention of IMPROVEMENTS IN
BOTTLES FOR CONTAINING AERATED LIQUIDS."
PROVISIONAL SPECIFICATION left by the said Hiram Codd at the Office of
the Commissioners of Patents on the 22nd October 1877.
HIRAM CODD, of Grove Lane, Camberwell, in the County of Surrey, Glass
Bottle Manufacturer, IMPROVEMENTS IN BOTTLES FOR CONTAINING AERATED
LIQUIDS."
"
This Invention has for its object improvements in that class of bottles for con-
taining aerated liquids which are closed by means of an internal stopper held up to
the mouth of the bottle by the pressure of gas within.
In the Specification of a former Patent granted to ine, No. 2621, in the year
1872, I described forming the necks of such bottles with inclined internal projecting
ridges, in order when the bottle had been opened by forcing back the stopper, to
impede the stopper from passing back to the mouth when the contents of the bottle
were being poured out.
According to my present Invention I construct an improved bottle, in which two
or more internal projecting ridges are so formed as to enable the stopper, to act
more efficiently in opening and keeping open the aperture of the bottle than stoppers
heretofore used. The ridges are not parallel with the body, but are inclined to it,
and are placed at such a distance apart that the stoppers cannot pass between them.
When the stopper is pushed away from the mouth, and drops to the bottom of thic
bottle, it passes readily along the sides and beyond the ends of these inclined
ridges; and when the contents of the bottle are being poured out the stopper comes
below the ridges, and is arrested by their ends, so that it cannot fall back to the
mouth, and so close the aperture of the bottle when it is desired that it should
continue open.

HIRAM CODD, of Grove Lane, Camberwell, in the County of Surrey, Glass
Bottle Manufacturer. "IMPROVEMENTS IN BOTTLES FOR CONTAINING AERATED
LIQUIDS."
This Invention has for its object improvements in that class of bottles for con-
taining aerated liquids which are closed by means of an internal stopper held up to
the mouth of the bottle by the pressure of gas within.
In the Specification of a former Patent granted to me, No. 2621, in the year
1872, I described forming the necks of such bottles with inclined internal projecting
ridges, in order when the bottle had been opened by forcing back the stopper, to
impede the stopper from passing back to the mouth when the contents of the bottle
were being poured out.
According to my present Invention I construct an improved bottle, in which two
or more internal projecting ridges are formed along the body of the bottle, so as to
enable the stopper to act more efficiently in opening and keeping open the aperture
of the bottle than heretofore. The ridges are not parallel with the body, but are
inclined to it, and are placed at such a distance apart that the stoppers cannot pass
between them. When the stopper is pushed away from the mouth, and drops to the
bottom of the bottle, it passes readily along the sides and beyond the ends of these
inclined ridges; and when the contents of the bottle are being poured out the
stopper comes below the ridges, and is arrested by their ends so that it cannot fall
back to the mouth, and so close the aperture of the bottle when it is desired that
it should continue open.
The Drawings hereunto annexed shew a bottle constructed as above described.
Figure 1 shews an external elevation of the bottle; Figure 2, a longitudinal
section of the same with the stopper away from the mouth of the bottle, and in the
position in which it remains during the time that the contents of the bottle are
being poured out.
Figure 3 is a transverse section of the bottle through the line A, B, Figure 1.
The stopper of the bottle shewn in these Figures is a sphere of glass, and when
closing the mouth of the bottle it rests against a ring of elastic material contained
in a groove formed around the interior of the head, as described in the Specification
of a former Patent granted to me.
The body b of the bottle is formed with two internal projections or ridges a, a,
inclined to one another; they are furthest apart at their ends which are nearest to
the bottom of the bottle, so that the stopper can readily roll between them whilst
their upper ends are nearer together, and at such a distance that the stopper cannot
pass between them,
When, in order to open the bottle, the stopper is pushed inwards, it drops readily
to the bottom of the bottle; when the bottle is turned over to pour out its
contents, the bottle is so held that its ridges a, a, are on the under side.
As the contents of the bottle are being poured out the stopper rolls down
towards the mouth of the bottle, and comes between the ridges a, and is arrested
by them near their ends where they converge together, as is shewn at Figure 2; if
these ends of the ridges are made to project somewhat over the centre of the stopper
the bottle might be completely inverted without the stopper being able to drop to
the neck of the bottle.
By arresting the stopper in the manner above described, the whole aperture of
the neck is left open for pouring out the contents.
If desired another pair of ridges a, a, might be formed on the opposite side of
the bottle, so that the bottle might be held with either side downwards whilst the
contents are being poured out.

page_text: The bottle is formed by being blown in a mould in the ordinary manner, the
mould being provided with internal projections where the ridges a are to be formed
in the bottle, as will be well understood. In the same way bottles provided with
other forms of loose internal stoppers may similarly be formed with inclined ridges
a, a, in the body of the bottle to catch the stopper, and hold it away from the neck
of the bottle whilst the contents are being poured out. For example, bottles closed
with internal stoppers, such as shewn at Figure 4, may be formed in this manner.
This stopper is now sometimes used, and is composed of a short cylinder of glass
carrying a ring of vulcanized india-rubber, which ring, when the stopper is closing
the mouth of a bottle, rests against a ledge or shoulder formed around the head, as
shewn.
Having thus described the nature of my Invention, and the manner of performing
the same, I would have it understood that I claim, the manufacture of bottles with
inclined ridges a, a, on the interior of the body to arrest and retain the stopper
whilst the contents are being poured out, substantially as herein-before described.
In witness whereof, I, the said Hirain Codd, have hereunto set my hand and
seal, this Nineteenth day of April, in the year of our Lord One thousand
eight hundred and seventy-eight.
