PROVISIONAL SPECIFICATION.
Improvements in and relating to Bottle-stoppers.
I, WILLIAM GAGE TWEEDY of Athenæum Terrace Plymouth in the County
of Devon Tutor do hereby declare the nature of this invention to be as
follows:-
:-
I make a rubber-cork or bottle-stopper of cylindrical or truncate-conical shape,
as regards that part which enters the neck of the bottle, but in the axis of this I
make a cylindrical hole communicating with the interior of a hollow elastic rubber
knob or bulb, which forms the upper part of the stopper. This bulb has no other
opening and serves three purposes.
(1) It serves as a handle.
(2) It is an elastic reservoir for air, or liquid, thus rendering the bottle less liable
to burst.
(3) By inserting a glass tube in the hole it forms a pipette or dropping tube
by which small quantities of liquid may be lifted in a manner that is well under-
stood.

Improvements in and relating to Bottle-stoppers.
I, WILLIAM GAGE TWEEDY of 8 Athenæum Terrace Plymouth, Devon Tutor
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 :-
Of the substance known as rubber," used in the manufacture of elastic goods,
I make bottle stoppers of cylindrical or truncate-conical or other suitable shape as
regards the part that enters the neck of the bottle, and along the axis of the stopper
I make a hole communicating with the inside of a hollow bulb which forms the knob
or handle of the stopper. I thus provide in the stopper and knob an elastic reservoir
for air or liquid in one piece.
P
This form of stopper has the following advantages:
(1) The part which enters the neck of the bottle conforms itself to any irregu-
larity, (by reason of the hole along its axis,) in the neck, better than a solid
plug can.
(2) The bulb forms an efficient handle.
(3) The bulb, being elastic, expands with any increase of pressure within the
bottle, thus making the bottle less liable to burst.
(4) By inserting a glass or other tube in the hole in the plug, a pipette is formed
by which small quantities of liquid may be removed from the bottle without pouring,
in a manner well understood.
The accompanying drawing shows a vertical axial section of the stopper when
used in this way.
B is the bulb, S the stopper N the neck of the bottle, T the
tube.
I do not confine myself to the shape of bulb and stopper shewn in the drawing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
(1) The combination in one article of an elastic rubber bottle-stopper and an

page_text: elastic rubber bulb, the bulb having an opening or inlet along the axis of the
stopper.
(2) The combination in one article of an elastic rubber bottle stopper and an
elastic rubber bulb, the bulb having an opening or inlet along the axis of the
stopper, in which opening I fix a glass or other tube to act as a prolongation of the
inlet, so forming a pipette or dropping tube.
