1, WILLIAM PHILLIPS THOMPSON F.C.S. M.L.M.E. of the Agency for Foreign
Patent Solicitors 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster and 323 High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
-
The invention relates to bottle stoppers, and has for its object to provide a stopper
of india-rubber, which, when distended, can be easily introduced into the neck of a
bottle, whilst on the removal of the pressure producing distension, the natural
elasticity of the stopper to resume its original shape causes it to apply itself tightly on
the inside of the bottle neck.
The form of the stopper is somewhat similar to a thimble closed at its upper part
by a lid, in the centre of which a hole is bored. Through this hole and in the axis of
the stopper, slides a rod, which being shifted downwards comes in contact with the
internal bottom of the stopper. By exerting a pressure on the said rod, the stopper
becomes longer and at the same time thinner, so that it can easily penetrate into the
neck of the bottle to be stoppered. As soon as the pressure exerted on the stopper
ceases, the stopper resumes its original form and diameter. The bottle is thus
hermetically closed and becomes capable of resisting considerable internal pressure,
if the internal diameter of the bottle neck is sufficiently narrow in proportion to
the outer diameter of the stopper. The stopper can easily be inserted in a bottle by
one hand.

I, WILLIAM PHILLIPS THOMPSON, F.C.S. M.I.M.E. of the Agency for Foreign Patent
Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street, Manchester, both in the
County of Lancaster, and 323 High Holborn in the County of Middlesex, Civil
Engineer 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 invention relates to bottle stoppers, and has for its object to provide a stopper
of india-rubber, which when elongated, can be easily introduced into the neck of a
bottle, whilst on the removal of the pressure producing elongation, the natural
elasticity of the stopper to resume its original shape causes it to apply itself tightly
on the inside of the bottle neck.
Referring to the drawings,
Figure 1 is a vertical section of a stopper constructed according to this invention.
Figure 2 is a plan of same.
The external part a of the stopper is formed of india-rubber and is somewhat
similar in shape to a thimble. closed at its upper part by a lid d, in the centre of
which a hole is bored. Through this hole and in the axis of the stopper, slides a rod b
which, being shifted downwards, comes in contact with the internal bottom of the
stopper. By exerting a pressure on the said rod, the stopper becomes longer and at
the same time thinner, as shown in dotted lines, so that it can easily penetrate-into the
neck of the bottle to be stoppered. As soon as the pressure exerted on the stopper
ceases, the stopper resumes its original form and diameter. The bottle is thus herme-
tically closed and becomes capable of resisting considerable internal pressure, if the
internal diameter of the bottle neck is sufficiently narrow in proportion to the outer
diameter of the stopper. The rod has preferably a collar or projection on its lower
portion to prevent its complete withdrawal from the stopper. The stopper can easily
be inserted in a bottle by one hand.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondents, I declare that what I claim is:
A stopper composed externally of an india rubber shell, and provided at its upper
end with a lid having a central hole, in which slides a rod in such manner that
pressure on said rod will cause the stopper to be elongated, and be easily passed into
the neck of a bottle, the stoppering of the bottle being effected by the tendency of the
stopper, when pressure on the rod is removed substantially as described, to resume its
original shape.
