Improvements in Stoppers
Year: 1899

page_text: ARTHUR ANDREWS, 245, Dalston Lane, London, N.W., Printer, do hereby
declare the nature of this invention to be as follows:-
-
This invention relates to improvements in stoppers for bottles. The same
is carried out as follows:-
I provide a taper piece upon which a ring of extensible material is carried
such as india rubber, so that when it is required to close a bottle or other con-
venient article, the extensible ring may be expanded the required amount. If
desired, the surface of the rubber ring may be roughened or corrugated for
increasing its gripping power, or the surface upon which it engages may if desired
be roughened or corrugated. The taper piece is provided with a projection
or head for the purpose of operating same, & may if desired be enlarged at one
end for the purpose of ensuring the withdrawal of the extensible ring aforesaid
when required from the bottle or other vessel.

Improvements in Stoppers
ARTHUR ANDREWS, 245, Dalston Lane, London, N.W., do hereby declare
18 to be
the nature of this invention and in what manner the same
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in stoppers for bottles and the same
is carried out as follows. I provide a taper piece upon which a ring of exten-
sible material, such as india rubber is carried so that when it is required to close
a bottle or other convenient article, the extensible ring may be expanded the
required amount. If desired the surface of the rubber ring may be roughened or
corrugated for increasing its gripping power and the surface upon which it
engages may if desired, be roughened or corrugated. The taper piece is provided
with a projection or head for the purpose of operating same and may if desired
be enlarged at one end for the purpose of ensuring the withdrawal of the
extensible ring aforesaid when required from the bottle or other vessel. For
the purpose of illustration I will now refer to the annexed drawings in which,
Figure one is a sectional side elevation showing my invention applied to a bottle.
Figure two longitudinal section through the stopper shown in Figure one. I

provide a taper piece a upon which a ring e of extensible material, such as india
rubber is carried, so that when it is required to close a bottle or other con-
venient article, the extensible ring c may be expanded the required amount. If
desired, the surface of the rubber ring c may be roughened or corrugated for
increasing its gripping power, or the surface upon which it engages, may if
desired be roughened or corrugated. The taper piece a is provided with a pro-
jection or head for the purpose of operating same, and if desired may be enlarged
at one end for the purpose of ensuring the withdrawal of the extensible ring
aforesaid when required from the bottle or other vessel. It will be seen that upon
inserting the taper piece carrying the extensible ring c into the neck of a
bottle, and upon pressing piece a, a certain distance through the ring c, the same
will be caused to engage upon the interior of the neck of the bottle, thus closing
or scaling same. The amount of taper of piece a may be altered to suit the shape
of configuration of the interior of the bottle neck as required, and the extensible
ringe may also be varied in its shape or configuration in order to enable it to be
adapted to the required surface.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The stopper for bottles and like articles substantially as described and
illustrated herein and for the purpose set forth.
2. In stoppers for bottles and like articles, a taper piece, provided with an
extensible ring of india rubber or such suitable material, said taper piece
having a head or projection for ensuring the withdrawal of the whole from the
neck of the bottle when required. The size of the taper piece and extensible ring
being adapted to close or seal the neck or outlet of a bottle or other article
substantially as described and illustrated herein and for the purpose set forth.
