Improvements in Bottle Stoppers.
We, SALO RADLAUER, of 3, Seydelstrasse, Merchant, and PAUL SCHROEDTER,
of 65, Oranienstrasse, Merchant, both of Berlin, in the Empire of Germany, 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 follow-
ing statement:―
This invention relates to a bottle-stopper of the kind most frequently used at
the present time for beer and mineral water bottles. The actual stopper mechan-
ism remains the same as formerly in its various forms of construction. On the
other hand, instead of the porcelain covers hitherto employed, firmly and
undetachably connected with the stopper mechanism, metal covers are used,
which are detachably connected therewith. Thus any damaged part can bo
exchanged without its being necessary to reject the whole stopper. Moreover
the manufacture is considerably simplified, as the closing cover and the closing
mechanism can be produced independently of each other.
In the accompanying drawing, the invention is illustrated in three different
forms. Figs. 1 to 3 show the first form in elevation and two vertical sections,
whilst Figs. 4 and 5 represent the second and third forms in vertical section.

The metal closing cover consists of the inner "cap" a with the washer b and
the outer "cap" c with the two side slots d d. The disc b is made preferably
of a cork previously rendered impervious, which is firmly held by the water
tight cap" border e. Between the caps a and c is a free space f for the press-
ing arm of the ordinary wire-stopper mechanism h which engages through
the slots dd. The free space is obtained by the pushing in of a third "cap" i,
against which the "cap a strikes. The cap is furnished with correspond-
ing slots k k.
Instead of the "cap" i, any other means may be employed in order
to secure the bearing space f for the pressing arm g. This pressing arm is
held firmly centrally and capable of rotating between the "
caps a and c which
engage tightly with one another. If a washer bis damaged, the "cap" a is
pressed out by means of a small instrument which is inserted through 7 and k
between a and i and a new cap" pressed in.

The closing cover may advantageously be furnished with a securing ring 1, of
angular cross-section, screwed on tightly from beneath on to the outer
cap" c
as far as the border e of the inner cap a. This securing ring prevents the
springing apart on widening of the slotted "cap" covering in the case of shocks
or the like and, consequently, the loosening and falling out of the inner "cap" a.
Figs. 4 and 5 represent the application of the invention for stoppers with
"folding" covers, that is to say, covers which can be turned back on a hinge,
and have a nose or projecting piece in front which is drawn down through the
stopper. In these cases, the pressure arm must be held firmly immoveably
between the " caps" and accordingly its cross-section is not circular but square
for example or in the form of a wire shackle the two arms of which engage
through two pairs of side slots. A pressure arm of the kind m (Figs. 4 and 5) is

page_text: furnished at the back with the hinge lug n and in front with the nose or pro-
jecting piece o.
In Fig. 4 the well known closing wire is connected by the arm p with the lug n
and furnished in front with a sliding piece q which is laid over the nose or pro-
jecting piece o and drawn down by means of the hand-lever r.
In Fig 5 the back connecting arm is composed of a strip of sheet metals and
the front closing-arm likewise of a strip of sheet metal t which takes hold above
the projection o of the pressing arm m by means of a nose-piece u.
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 bottle-stopper, distinguished by a closing-cover made of two metal
caps" a c engaging tightly one over the other, with a washer b, between which
the pressing arm y (of a wire-lever closing mechanism) which engages through
slots d, is firmly centrally and detachably held and capable of rotating in a free
space f.
2. A bottle-stopper according to Claim 1, the closing cover of which is fur-
nished with a securing ring 1 screwed from beneath on to the outer "
"
cap c for
the purpose of preventing any springing out or widening of the slotted outer
cap c and the falling out of the inner tightening or packing "cap
"

a.
3. A bottle-stopper according to Claim 1, the closing cover of which is con-
nected with a pressing arm m, which arm m is linked at the back to the closing
mechanism so as to "fold" and furnished in the front with a nose piece or pro-
jection o, with which the closing lever engages.
