Improvements in Bottle Stoppers.
FREDERICK WILLIAM SCHROEDER, Engineer, and PATRICK WILLIAM MORAN,
Gentleman, both of 30, Maiden Lane, London, W.C., do hereby declare the
nature of this invention to be as follows:-
Our invention relates to bottle stoppers in which a cork is rotatably con-
nected to a screw-cap that is adapted to screw with an internal or external screw
thread on to an external or internal screw thread formed on the neck of the
bottle, so that on screwing the cap on to the neck of the bottle the cork is
forced in without being turned with the cap. Our present invention has for
its object to simplify the construction of such stoppers, and it consists in securing
to the upper end of the cork a metal strip or plate which has at its middle an
upward projecting loop which is passed through a central hole of the screw-cap,
and has a metal ring passed through its end which projects beyond the cap.
Thus the ring effectually secures the cork in the cap, while the latter can be
turned round freely on the loop. The metal band or plate is secured to the cork
either by forming it with claw-shaped ends that are bent down a short distance
over the sides of the cork and are then driven into the latter, or the plate may be
of disc form with claws all round it that are bent inwards so as to grip the
upper end of the cork. Or any other arrangement may be employed for fixing
the metal strip or plate to the cork.

Peppers,
We, FREDERICK WILLIAM SCHROEDER, Engineer, and PATRICK WILLIAM MORAN,
Gentleman, both of 30, Maiden Lane, London, W.C., 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:—
Our invention relates to bottle stoppers in which a cork is rotatably con-
nected to a screw-cap that is adapted to screw with an internal screw thread on
to an external screw thread formed on the neck of the bottle, so that on screwing
the cap on to the neck of the bottle the cork is forced in without being turned with
the cap. Our present invention has for its object to simplify the construction of such
stoppers, and it consists in securing to the upper end of the cork a metal strip

through a central hole of the screw-cap, and has a metal ring passed through
its end that projects beyond the cap.
Thus the ring effectually secures the cork in the cap, while the latter can
be turned round freely on the loop.
Fig. 1 of the accompanying drawing shews a vertical section of a stopper con-
structed according to our invention; Fig. 2 shews a plan, and Fig. 3 shews a
plan of the cork detached. Figs. 4 and 5 shew modifications.
The cap a which may be of aluminium or other suitable metal or material has
an internal screw thread for screwing on to the neck of a bottle, and a central
hole a through which is passed the loop ' of a band of metal secured to
the cork c, the loop 6' being secured in the cap by having a metal ring d passed
through it. This ring may either be an ordinary split spring ring as shewn at
Fig. 1, or it may be of solid metal as at Fig. 2. The metal band b is secured
to the cork by being bent down a short distance over its sides and having its
serrated ends driven into the cork as shewn.
It will be seen that the above described construction affords an exceedingly
simple but effective rotatable connection between the cork and the cap, so that
on screwing the cap on to a bottle neck the cork is forced into the latter with-
out rotation. Should at any time the cork become defective and require renewal,
this can be readily effected by simply removing the ring d from the loop b¹.
In place of the band b a disc e Fig. 4 may be employed having a loop el formed
thereon by stamping as shewn, and having either two, three or more serrated
claws that are driven into the cork e as shewn, or, the disc may have a number
of teeth e as at Fig. 5 that are driven into the cork.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, we declare that what
we claim is:-
A bottle stopper consisting of the combination of a screw cap adapted to screw
on to the neck of a bottle and a cork to which is secured a metal plate having
a loop formed thereon which is passed through a central hole in the cap and is
secured therein by having a metal ring passed through it substantially as
described.
