I, JOHN CLAYTON MEWBURN of 55 and 56 Chancery Lane in the County of
Middlesex, Fellow of the Institute of Patent Agents, do hereby declare the nature
of this invention to be as follows:-
This invention relates to means or apparatus for stopping bottles especially those
containing champagne and other gaseous or effervescing liquids and the improve-
ments are based upon the employment of caoutchouc or elastic material as part of
the stopper, this caoutchouc being forced against the inside of the bottle mouth or
neck so as to effect a hermetic closure.
According to one modification of the invention the stopper is formed of a plug or
stem with an enlarged round lower end and a screw thread at top; this latter
receives a nut or screw cap forming the top of the stopper and when screwed home
exerting pressure through the intermediation of a washer upon a collar or ring of
caoutchouc on the central part of the plug which collar is thereby squeezed or
pressed out against the inside of the bottle neck. The lower part of the stopper
is covered with paper, parchment or other suitable waterproof material in order to
prevent the liquid coming in contact with the caoutchouc.
In another modification the lower end of the plug or stem is of truncated conical
form and the caoutchouc collar covers this part as well as the central portion of the
plug. The washer has a circular bead or rib which corresponds to a groove of
similar shape formed in the screw cap or nut; this arrangement is intended to
insure the concentricity of the washer which should exert its pressure equally upon
the entire surface of the collar. Shallow. grooves may be formed upon the screw
cap to receive and keep in position the fastening wires.
In another modification the nut or screw cap is arranged so as to receive the
ordinary bail or capsule fastening. The washer is the same as in the modification
first described but is arranged so that the parchment covering may be made to
entirely prevent the contact of the caoutchouc with the liquid in the bottle.
In another modification the stopper is made of caoutchouc or elastic material
provided likewise with a protective covering of paper parchment or the like and
also with a washer of the same material to fit on the top of the bottle neck. The
stopper is hollowed out in the centre and a plug or stem is pushed into the hollow
to force out the caoutchouc against the inside of the neck of the bottle. This plug
or stem which has preferably an enlarged inner end is kept in place by a metallic
cap which presses upon the head of the stopper so as to obtain absolute hermeticity.
The cap has claws which fasten underneath the rim of the bottle neck and are
secured thereto by means of wire twisted round the neck.

page_text: 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 means or apparatus for stopping bottles especially those
containing champagne or other gaseous or effervescing liquids and the improvements
are based upon the employment of caoutchouc or elastic material as part of the
stopper, this caoutchouc being forced against the inside of the bottle mouth or neck
so as to effect a hermetic closure.
According to one modification of the invention represented in vertical section in
Figure 1 of the accompanying drawings the stopper is formed of a plug or stem a
with an enlarged round lower end and a screw thread cat top; this latter
receives a nut or screw cap d forming the top of the stopper and when screwed
home exerting pressure through the intermediation of a washer f upon a collar or
ring g of caoutchouc on the central part a of the plug which collar is thereby
squeezed or pressed out against the inside of the bottle neck. The lower part of
the stopper is covered with paper, parchment or other suitable waterproof
material in order to prevent the liquid coming in contact with the caoutchouc.
In another modification represented in Figures 2 and 3 the lower end of the
plug or stem a is of truncated conical form and the caoutchouc collar g covers the
side of this part as well as the central portion a of the plug. The washer f has
a circular head or rib m which corresponds to a groove of similar shape formed in
the screw cap or nut d; this arrangement is intended to insure the concentricity
of the washer f which should exert pressure equally upon the whole of the upper
surface of the collar g. Shallow grooves n n (Figure 3) may be formed upon the
screw cap d to receive and keep in position the fastening wires.
In another modification represented in Figure 4 the nut or screw cap d is
arranged so as to receive the ordinary bail or cap fastening seen in Figures 5, 6,
and 7. The washer f is the same as in the modification shown in Figure 1 but
is arranged so that the parchment covering may be made to entirely prevent the
contact of the caoutchouc with the liquid in the bottle.
h
In the modification shown in Figures 5, 6 and 7 the stopper i is made of caoutchouc
or elastic material provided likewise with a protective covering of paper, parch-
ment or the like and also with a washer of the same material to fit on the top
of the bottle neck. The stopper i is hollowed out in the centre and a plug or stem j
is pushed into the hollow to force out the caoutchouc against the inside of the neck
of the bottle.
This plug or stem which has preferably an enlarged inner end is kept in
place by a metallic cap k which presses upon the head of the stopper so as to
obtain absolute hermeticity. The cap has claws ll which fasten underneath the
rim of the bottle neck and are secured thereto by means of wire twisted round
the neck.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me, and in what manner the same is to be performed,
I declare that what I claim is :-
The several means or apparatus for stopping bottles substantially as represented
in the accompanying drawings and hereinbefore described.
