Improvements in Locking Devices for the Stoppers of Bottles, Jars,
and the like.
We, WALTHER KÖTTGEN, of 42, Güntzelstrasse, Wilmersdorf, and MAX PREC-
KELT, of 41, Prenzlauer Allee, both in Berlin, in the Empire of Germany, Mer-
chants, do hereby declare the nature of this invention to be as follows:
This invention relates to certain new and useful improvements in locking
devices for the stoppers of bottles jars and the like and more especially to that
class of stoppers, in which, by turning a lever downward, a hook is caused to
engage with and pull downward the cover plug proper, hinged at one side to the
neck of the bottle, pressing it tightly upon a washer of resilient material, inter-
posed between the cover and the upper edge of the neck of the bottle and thereby
securely closing the mouth of the bottle.
The device consists principally of three parts, a member linked or pivoted to
the neck of the bottle, a stopper engaging hook, adapted to engage the front end
of the cover or stopper, and the pressure lever. The latter two parts are arranged
one on either side of the link member and are connected with each other in such
a way as to permit of the lever part being. swung around upward or downward
and of the two parts sliding up or down along the member linked to the neck of
the bottle. This up and down motion is limited by a slot provided in the link
member within which is guided a pin connecting the lever with the hook shaped
part.
In carrying the invention into practice, the upper end of the hook shaped part
is adapted to engage the cover. The member is linked or pivoted at its lower
end to a wire or like ring encircling the neck of the bottle, and is provided at
its upper end with a shoulder. In this member a slot is provided within which
is guided a pin connecting the engaging hook with the pressure lever. This
latter can be turned up or down about the said pin. Upon an eccentric part of
the pressure lever rests the shoulder of the link member. By turning the pres-
sure lever downward from its raised position the link member by means of its
shoulder will offer a resistance to the eccentric portion of the pressure lever and
cause the pin and with it the engaging hook to descend, the pin moving in the
aforementioned slot. In the lowermost position of the pressure lever the flat-
tened portion of the lever eccentric will bear against the shoulder of the link
member and prevent the parts from inadvertently being released. A nose or
stop prevents the lever from being turned too far.
During this downward motion the hook engages the front end of the cover
and presses the latter firmly upon an elastic washer interposed between the
cover plug and the upper edge of the neck of the bottle. The rear part of the
cover is provided with a transverse bore for receiving the rectangularly bent ends
of two wires which are twisted about each other and are provided with eyes at
the other ends. By means of these eyes the wire link is connected to the pro-
jecting ends of the wire ring encircling the neck of the bottle.

page_text: The lever arrangement may be modified by providing two pressure levers
adapted to turn upon a common pin in opposite directions, and both bearing
against the shoulder of the link member.
The locking device may be used in connection with a bottle neck having a
ground upper edge and a correspondingly ground cover surface, so that the use
of an elastic washer is obviated. In this case a wire ring surrounds the cover
which is provided for that purpose with a groove and the said ring is formed
at its front with a bent-out portion or loop and at its rear with two eyes. The
ends of the wire hinge engage these eyes and the hook upon being pulled down by
the pressure lever, engages the said bent-out portion of the ring and presses
the two ground faces firmly together.
According to another modification we use the locking device in combination
with a cover which is pressed out of sheet metal and contains a disc or plate of
elastic material such as cork for instance. The front part of this cover is pro-
vided with a hook to engage the hook of the locking device and the rear part
with an eye with which the ends of the wire link is engaged to form the hinge.
- Instead of forming an eye at the rear part of the cover as above described the
said cover may be provided with an extension passing downward and engaging
at its free end the wire ring surrounding the neck of the bottle.

Improvements in Locking Devices for the Stoppers of Bottles, Jars,
and the like.
We, WALTHER HÖTTGEN, of 42, Güntzelstrasse, Wilmersdorf, and MAX PREC-
KELT, of 41, Prenzlauer Allee, both in Berlin, in the Empire of Germany, Mer-
chants, 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:-
-
This invention relates to certain new and useful improvements in locking or
fastening devices for the stoppers of bottles jars and the like and more especially
to that class of stoppers in which, by turning a lever downward, a hook is caused to
engage with and pull downward the cover plug proper, hinged at one side to the
neck of the bottle, pressing it tightly upon a washer of resilient material, inter-
posed between the cover and the upper edge of the neck of the bottle and thereby
securely closing the mouth of the bottle.
The device consists principally of three parts, a member linked or pivoted to
the neck of the bottle, a hook, adapted to engage the front end of the cover or
stopper, and the pressure lever. The latter two parts are arranged one on either
side of the link member and are connected with each other in such a way as to
permit of the lever part being swung around upward or downward and of the
two parts sliding up or down along the member linked to the neck of the bottle.
This up and down motion is limited by a slot provided in the link member within
which is guided a pin connecting the lever with the hook shaped part.
In the accompanying drawings.

Figure 12 is still another modification of cover in combination with my im-
proved locking device, partly in section and with the front working parts of
the locking device omitted.
Figure 13 is a sectional view showing the application of the previously described
stopper to preserve tins, jars and the like.
Figures 14 and 15 are a vertical section and a plan respectively of a modified
arrangement.
Like letters of reference designate similar parts in the several views of the
drawings.
a is the hook shaped part, the upper end of which is adapted to engage with
the cover c.
The member b is linked or pivoted at its lower end to a wire or like
ring encircling the neck of the bottle, and is provided at its upper end with a
shoulder b. In this member a slot 2 is provided within which is guided a pin f
connecting the engaging hook a with the pressure lever e. This latter can be
turned up or down about the said pin. Upon an excentric part e¹ of the pressure
lever e rests the shoulder b¹ of the link member b, as clearly shown in Figure 3.
By turning the pressure lever e downward from its raised position the link
member by means of its shoulder 6 will offer a resistance to the excentric e
and cause the pin f and with it the engaging hook a to descend, the pin moving
in the aforementioned slot 2. In the lowermost position of the pressure lever e
the flattened portion of the lever excentric will bear against the shoulder b
and prevent the parts from inadvertently being released. A nose or stop e³ pre-
vents the lever from being turned too far.
During this downward motion the hook a engages the front end of the cover c
and presses the latter firmly upon an elastic washer g interposed between the
cover plug and the upper edge of the neck of the bottle, as is shown in Figure 2.
The rear part of the cover c is provided with a transverse bore for receiving
the rectangularly bent ends of two wires k, which are twisted about each
other and are provided with eyes at the other end. By means of these eyes the
wire link is connected to the projecting ends of the wire ring & encircling
the neck of the bottle as shown in Figures 2 and 5.
In Figure 6 a modification of the fever arrangement is shown in which two
pressure leverse are provided, adapted to turn upon a common pin f in opposite
directions, and both bearing against the shoulder 6 of the link member b.
In Figure 7 the locking device is represented.in .connection with a bottle neck
having a ground upper edge and a correspondingly ground cover surface, so
that the use of an elastic washer is obviated. In this case a wire ring surrounds
the cover which is provided for that purpose with a groove and the said ring is
formed at its front with a bent-out portion or loop and at its rear with two
eyes. The ends of the wire hinge engage these eyes, as is shown in
Figures 7 and 9 and the book a, upon being pulled down by the pressure lever e,
engages the said bent-out portion of the ring i and presses the two ground
faces firmly together, as at h in Figure 7.
Figure 10 shows the locking device in combination with a different style of
In this case the cover is pressed out of sheet metal and contains a disc
cover.

page_text: or plate m of elastic material, such as cork for instance. The front part of this
cover is provided with a hook c¹ to engage the hook a of the locking device and
the rear part with an eye c³ with which the end of the wire link is engaged to
form the hinge.
A modification of this kind of cover is shown in Figure 12 in which the
extension of the cover c is extended downwardly and encircles at its free end
the wire ring d placed around the neck of the bottle.
The other working parts of the locking device are not shown, as they do not
differ from the parts described with reference to the other figures.
In the arrangement shown in Figure 13 the cover is firmly pressed down by
means of a transverse flat spring o having its rear end secured to the cross-bar k
of the joint, while its front end of is slightly bent upwards and formed with a
hook for engagement with the hook of the previously described eccentric
device. The locking device is an elastic one as the drawing-in of the eccentric-
device, i.e. the depression of the hand-lever e, causes the transverse spring o to
be first straightened.
Figures 14 and 15 show a modification of the arrangement shown in Figure 13,
in which the transverse spring o is constructed of a wire which is so twisted
around a knob of the cover as to form a permanent connection therewith,
causing the cover to be removed with the transverse-spring o when turning the
latter backwards. The front end o¹ of the spring is formed with a loop on to
which the hook a of the eccentric device engages. Also in this arrangement
the front portion of the spring o is bent upwards so as to render the fastener
elastic.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. A fastening for stoppers of bottles, jars and the like having a locking
device articulated to a band characterized by the fact that the said device con-
sists of two overlapping parts a bone of which is adapted to move endwise and
thereby cause the tightening of the cover e; such endwise motion being effected
by means of a lever e having eccentric portion e forming part of the locking
device and adapted to turn up and down and which lever is connected to the
portion of the locking device in such a manner as to enable it to act with its
eccentric part against a projection 61 of the said part 6 of such locking device.
2. A fastening for bottle stoppers and the like as claimed in Claim 1, in which
the lever e with the eccentric portion el, is secured in its closed position, by the
engagement of the straight contact surface e² with the projection of the part b.
3. A fastening for bottle stoppers and the like as claimed in Claim 1 having
mounted upon a common pivot f two levers with eccentric discs e¹ which when
operated to tighten the locking device are caused to move towards each other.
4. A fastening or locking device for bottle stoppers and the like as claimed in
Claim 1 provided with a rear link formed of two parts k k twisted together at
the centre and secured in position by attaching the ends to the cover c and to the
band d surrounding the bottle neck.
5. A fastening or locking device for bottle stoppers and the like as claimed in
Claim 1, combined with a cover c (Figures 7 to 9) in which a tight point is pro-
duced by the grinding of the stopper flat upon the mouth of the bottle or the
like.
6. A locking device for bottle stoppers as claimed in Claim 1. combined with
a hollow cover c. Figures 10 to 12 provided with an inserted cork device m for
forming the joint.
7. A fastening or locking device for bottle stoppers and the like as claimed in
Claims 1 to 6. in which a rigid plate 2 (Figure 12) of the cover c is used in lieu
of a loose rear link.
8. The employment of the fastening or locking device as claimed in Claim 1,

page_text: for jars, tins or the like, characterized by the provision of a transverse spring o
adapted to be turned down over the cover and provided with end hooks o¹
engaging with the tightening hook of the locking device which latter depresses
the transverse spring and so tightens down the cover.
9. A modified form of the locking device claimed in Claim 8, in which the
transverse spring is secured to the cover in such a manner that this latter is
removed together with the said fastener.
