COMPLETE SPECIFICATION.
Improvements in Fastenings for Bottle-stoppers.
We, RUDOLF LIEBIG, of No. 6 Hübner Strasse, Dresden in the Kingdom of
Saxony, German Empire, Director in a Manufactory, and THE AKTIEN-
GESELLSCHAFT FÜR GLASINDUSTRIE Vorm. FRIEDR. SIEMENS at the same
place, a corporation organized under the laws of the Kingdom of Saxony, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The present irvention relates to fastenings for bottle-stoppers and its object. is
to facilitate the manufacture of the bottle to the mouth whereof the fastening is
to be applied, as well as that of the fastening itself, to render the employment.
of the fastening more convenient and to obtain a closure of the bottle which
is tighter and more resistant against internal pressure than those at present
in use.
For this purpose the mouth of the bottle is formed with a bulb having a
groove, and into the said groove is placed an open ring of wire and secured on
the bottle by a strip of metal which braces together the ends of the ring bent
to a suitable shape. To the said ring is hinged the stopper either directly or by
means of a link, and in the latter case the aforesaid bracing-strip may be placed.
on the said link, which may be composed of two parts. Opposite to the stopper-
hinge there is connected to the ring the clasp whereby the stopper is held down
on the bottle-mouth, and with the said clasp may be combined a lever forming
therewith a knee-lever and by. means of which the securing and releasing of the
stopper is facilitated.
In the annexed drawings the said fastenings for bottle stoppers are represented
in various modifications.
In Figs. 1 and 3, a is the neck of the bottle having at its mouth a thickened
portion or bulb provided with a groove, d is the stopper made of porcelain or other
suitable material, t the wire ring and h the clasp. At its front side the ring tis
bent to form the eyes (see also Fig. 10; in which is pivoted the clasp h, while
the ends to of the ring are bent upward to receive the brace k, and then inward to
form the pivots t2 engaging in the hole g of the stopper and on which the stopper
turns. After the ring has been slipped into the groove on the bottle-neck, and
the pivots have been inserted into the hole g, the brace k, consisting in a
strip of sheet metal, is put on and secured by a suitable pair of pliers. The clasp h
being pivoted to the ring t, may be turned into the position shown in Fig. 1' in
dotted lines.
In the modified construction of the clasp, represented by Fig. 2, the ends of the
clasp are passed through bows formed on the ring t, and the portions thereof,
projecting through the said bows, are bent to such shape as that they allow the
clasp to be swung back only so far as is necessary for the same just to release the
stopper. The clasp is thus always ready to be reengaged with the stopper, which
is of advantage in bottles containing aerated water.
If it is required that the stopper be capable of being turned down against the
Deck of the bottle, the same is connected to the ring t by means of a link composed
of the two parts bb, Figs. 4 and 5, both ends whereof are bent inward, the lower

page_text: ends being passed through eyes t³ formed on the ring t, while the upper ends b²
are engaged in the hole g of the stopper, a double hinge being thus produced.
The brace k is placed on the said parts bb; it thus serves for the two
purposes of uniting these parts and securing the ring t on the mouth of the
bottle.
In the arrangement shown by Figs. 6, 7 and 9, the clasp 2 is combined with
a lever c constituting with the same a knee-lever. For this purpose the ends of
the clasp are bent to form pivots which engage in eyes c¹ on the said lever c,
while the latter has pivots turning in the eyes ton ring t. Moreover, the
clasp is made in form of a bail adapted to be thrown over the nose of the stopper
and not projecting over the same. The parts are so arranged in respect to each
other that, when the bail or clasp h³, being engaged with the stopper, is drawn
down by swinging the lever c against the neck of the bottle, the stopper will be
secured (see Figs. 6 and 7); whereas when the lever c is raised, as shown in Fig. 9,
the stopper is free to be thrown back.
The connection between the stopper and the ring is in this case established by a
link 63 made of a single piece of wire passing through the hole of the stopper an
pivoted in the eyes t³ of the ring, while the brace k is placed on the ends of the
ring. But, if preferred, either of the two other described arrangements of the
connections between the ring and the stopper may be employed with the knee-lever
fastening.
Figs. 11 to 16 show the way how the clasp combined with lever c, as described
with reference to the preceding Figures 6, 7 and 9, may be applied to old
fastenings that are at present in use and known. In Figure 11 is represented
the old type of fastening; in this both the link carrying the stopper and the
clasp are connected to the ring t. In order to apply hereto a clasp with lever,
a lever as c in Fig. 12-16 with eyes t¹¹ is arranged to turn on the ring t,
and the ends of the clasp / are bent to form pivots which engage in eyes c¹ of the
lever c.
Having now particularly described the nature of this invention and in what
manner the same is to be performed, we declare that what we claim 18 :-
1. The combination, with the neck of a bottle having a groove, of a stopper,
an open ring of wire placed in the said groove, a brace whereby the ring is
secured on the bottle-neck, means for hinging the stopper to the ring, and a clasp
connected to the ring and adapted to be thrown over the stopper, substantially as
described.
2. The combination, with the neck of a bottle having a groove, of a stopper d,
an open ring of wire placed in the said groove, a link hinged to the ring
and to the stopper, a brace whereby the ring is secured on the bottle-neck and a
clasp connected to the ring and adapted to be thrown over the stopper, substantially
as specified.
3. The combination, with the neck of a bottle having a groove, of a stopper d,
an open ring t of wire placed in the said groove, a link composed of two parts
pivotally connected to the ring t and the stopper, a brace whereby the ring is
secured on the bottle-neck and the parts of the link are united, and a clasp
connected to the ring and adapted to be thrown over the stopper, substantially as
specified.
4. The combination, with the neck of a bottle having a groove, of a stopper d,
an open ring of wire placed in the said groove, a brace whereby the ring is
secured on the bottle-neck, means for hinging the stopper to the ring, the lever c
jointed to the said ring, and clasp 2 adapted to be thrown over the stopper and
jointed to the lever c so as to form together with the latter a knee-lever,
substantially as set forth.
5. The combination, with the neck of a bottle having a groove, of a stopper d,
a ring of wire placed in the said groove, a link hinged to the ring t and the

page_text: stopper, lever c also hinged to the ring and having eyes c¹ to which the clasp /³ is
pivotally connected, substantially as described.
