Year: 1879

page_text: LETTERS PATENT to Nicolay Fritzner, of the City of Berlin, in the Kingdom
of Prussia and Empire of Germany, Merchant and Manufacturer, for the
Invention of "IMPROVED STOPPER FOR BOTTLING EFFERVESCENT LIQUIDS."
Sealed the 8th June 1880, and dated the 24th December 1879.
PROVISIONAL SPECIFICATION left by the said Nicolay Fritzner at the Office
of the Commissioners of Patents on the 24th December 1879.
NICOLAY FRITZNER, of the City of Berlin, in the Kingdom of Prussia and
Empire of Germany, Merchant and Manufacturer. "IMPROVED STOPPER FOR
BOTTLING EFFERVESCENT LIQUIDS."
The Invention relates to those mechanical stoppers which are employed on
bottles containing effervescent or aerated liquids, and its object is to furnish a
stopper which will enable bottles to be readily and speedily filled with such
effervescent liquids, which exert a great expansive pressure without removing the
stopper proper from the opening of the bottle, which heretofore it has been
necessary to do.
To accomplish this object the stopper proper of such stoppering devices, in
which the former is pressed to the mouth of the bottle by toggle-levers, hinged
links, and hooks or other mechanical contrivances fastened to the neck of the
bottle, an elastic flat packing ring being interposed between the stopper proper and
the mouth piece of the bottle, is provided with an eccentric perforation or vent
piercing the body of it from the top to the lower side, and the lower end of which
is closed by the said rubber packing ring serving as a valve or cover for this per-
foration. The stopper proper may be formed on its more or less straight top with
a projecting annular ring intended to make at the moment of filling the bottle a
tight joint with the rubber lining of the filling cock of the reservoir containing
the aerated liquid. But the top of the stopper proper may also be left more or
less flat if the lining of the filling cock is provided with an annular projection, the
object of both devices being to secure to the liquids a free passage from the reservoir
to the perforation or hole of the stopper,

page_text: To fill a bottle furnished with the improved stopper with effervescent liquid it is
in a closed state put under the filling cock, and pressed from below against its
packing lining. The filling cock being opened the liquid rushes into the bottle,
the valve or cover of the perforation yielding to it till the same pressure in the
bottle is reached as that existing in the reservoir.
By lifting the stopper a little the atmospheric air compressed in the bottle is
allowed to escape till the bottle is filled entirely, when the stoppering device is
fully shut and the bottle removed. The elastic ring formning the packing between
the stopper and the bottle, and at the same time the valve or cover for the per-
foration, is pressed to the lower end of the latter, and prevents any escape of the
aerated liquid, even if the pressure of it be as heavy as 5 to 6 atmospheres.

NICOLAY FRITZNER, of the City of Berlin, in the Kingdom of Prussia and
Empire of Germany, Merchant and Manufacturer. "IMPROVED STOPPER FOR
BOTTLING EFFERVESCENT LIQUIDS."
The Invention relates to that class of mechanical bottle stoppers, the stopper
proper of which is pressed tightly against the mouthpiece of the bottle by toggle
levers or other mechanical devices, an elastic rubber disc or ring being interposed
between the stopper and the bottle, and which are used on bottles containing
effervescent or aerated liquids; and the object of the present Invention is to furnish
a stopper which will allow the filling of the bottle with an effervescent liquid,
exerting a great expansive pressure without the necessity for removing the stopper
from the mouth of the bottle, whereby the whole filling operation is performed with
rapidity and ease.
And in order that the said Invention may be more clearly understood, and
readily carried into effect, I will proceed, aided by the accompanying Drawings,
more fully to describe the same
Similar letters of reference indicate corresponding parts in the various Figures.
Figure 1 shows my improved stopper applied to a bottle by toggle levers pivotted
in the glass of the bottle mouthpiece.
Figure 2 is a top view of this stopper, and
Figure 3 is an underside view thereof.
Figure 4 represents a similar stopper applied to the bottle by a lever device
constructed in a different manner from that shown at Figure 1.
Figure 5 shows a bottle furnished with my improved stopper in position for
being filled with the effervescent fluid by means of the usual cock, which is
however slightly modified to suit this stopper.
Heretofore it was necessary when filling a bottle furnished with a mechanical
stoppering device with an effervescent fluid to place the bottle with the stopper
opened under the filling cock, and to allow the atmospheric air to escape from the
bottle through an auxiliary escape cock connected with the filling cock, as is well
known. When filled the bottle was removed from under the filling cock, and tho
stopper quickly adjusted and closed. These operations were very difficult to
perform even under a pressure of two atmospheres, and a squirting of the liquid,
and consequently a great loss of the pressure and of material was unavoidable
when the pressure of the liquid was allowed to exceed two atmospheres.
My Invention obviates all these disadvantages, allows a more rapid filling, and
prevents any loss of liquid or pressure.
a is the stopper proper formed of any suitable material, such as porcelain, glass,
or metal pressed to the mouth of the bottle by means of any convenient
mechanical closing device h. The annular rubber disc d formed to the neck of the
button c, and interposed between the stopper a and the mouthpiece ƒ of bottle,
ensures a tight joint. The top of the stopper a is provided with an upwardly
projecting annular ring b, and is pierced eccentrically by a hole or perforation 7.
This hole or perforation opens on the underside of the stopper a close to the neck
of the button c, which button just at this point is formed with a flat or with a
portion of its circumference removed. When the bottle is filled and the stopper
closed the internal pressure of the liquid presses the rubber & against the hole or
perforation, thereby preventing the oscape of gas even under a pressure of from
four to five atmospheres.

page_text: In order to fill a bottle furnished with my improved stopper with effervescent
liquid it is placed under the filling cock 8 (which has no auxiliary escape cock), as
shown at Figure 5, and pressed upwards against the fat rubber ring m of the
filling cock; the annular ring b of the stopper a will then make a tight joint with
the rubber m. After having opened the cock 8 the liquid will be forced from its
reservoir through the passages o into the hole or perforation 1, and by depressing
or forcing downward the rubber d it will flow into the bottle. As soon as the
pressure in the bottle has reached that in the reservoir the compressed atmospheric
air in the bottle, which for the moment hinders the entire filling thereof, is allowed
to escape by slightly raising the stopper a by means of the closing device h, and
the liquid then rushes into the bottle and fills it entirely. When the bottle is full
the closing device is readjusted and the bottle removed from the filling cock.
It will be understood that instead of providing the stopper a with a ring b
capable of being pressed against the ring cushion m the stopper a may be made
flat, and the cushion m provided with a projecting annular ring. All that has to
be observed is to establish a free communication between the passage o of the
filling cock 8 and the hole or perforation l.
Having thus described the nature of the said Invention, and the mode in which
the same is carried into effect, I would have it understood that what I claim
is,―
First. A perforation 7 in the stopper proper a of a mechanical stoppering device
acting in combination with the usual elastic rubber joint d as a valve for the hole
or perforation 6, in manner substantially as herein shown and described and for
the purpose explained.
Second. Forming a perforated and valved stopper a with an annular projecting
ring b on its upper part, substantially as herein shown and described and for the
purpose stated.
In witness whereof, I, the said Nicolay Fritzner, have hereunto set my hand
and seal, this Eighteenth day of June, in the year of our Lord One.
