Improvements in Stoppering Bottles.
We, SAMUEL KERSHAW, of 35, Kent Street, Rochdale, in the County of
Lancaster, Clerk, and JAMES TOMLINSON, of 143, Oldham Road, Rochdale, afore-
said, Brewer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to lessen the danger and liability of the bursting
of bottles stoppered with screw or similar stoppers containing mineral waters and
other fermented or effervescent liquors or drinks.
For this purpose instead of the usual flat or tubular india rubber rings which
are placed against the shoulder of such stoppers we propose to make the rubber
rings with tapered or bevilled edges, which fit against the inside or on the top of
the neck of the bottles and form a tapered or conical bearing, thus allowing
for the escape of any excess of gas and preventing or minimising the liability of
the bottles bursting.
Or instead of making the india rubber rings with bevelled edges the shoulder
of the stopper may be tapered or bevelled off thus allowing a conical seating for
ordinary flat rings.

improvements in Stoppering Dotties.
We, SAMUEL KERSHAW, of 36, Kent Street, Clerk, and JAMES TOMLINSON, of
143, Oldham Road, Brewer, both of Rochdale, in the County of Lancaster, 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:.
This invention is for an improvement in the stoppers of bottles that are formed
with a screw thread to screw into the neck of the bottle and is intended to lessen
the danger and liability of the bursting of bottles containing mineral waters and
other fermented or effervescent liquors or drinks that are stoppered with screw or
similar stoppers. In the accompanying drawing Figs. 1 and 2 show sections of
the necks of screw stoppered bottles with our invention applied. In bottles that
are stoppered with a screwed plug it has hitherto been the practice to place a flat
or tubular india rubber ring against the shoulder of the stopper to press inside the
7 017

page_text: mouth of the bottle; with this form and manner of applying an india rubber ring
the escape of any excess of
Igas or excessive pressure within the bottle is prevented
and the bottle is consequently liable to burst.
For the purpose of this invention we make the rubber ring d with a tapered
or bevelled edge as 6 Fig. 1 so as to fit against the inside tapered portion or on the
top of the neck a of the bottle, and form a tapered or conical seating or bearing
when pressed by the stopper, thereby permitting the escape of any excess of gas
or undue pressure within the bottle. In a modification of our invention shown in
Fig. 2 we form a bevel as c on the stopper, against which the inner edge of a flat
rubber ring d is placed, the flat side of said ring resting on the bevel e formed on
the inside of the top of the neck a of the bottle.
By these means when the internal pressure arising from mineral waters and
other fermented or effervescent liquors or drinks contained in a screw stoppered
bottle is excessive, the bevelled or angular formation of the rubber rings herein-
before described permits the excess gas to escape and the bottle is prevented
bursting.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
111
1. In bottles for containing mineral waters and other fermented or effervescent
liquors or drinks that are stoppered with screw or similar stoppers the combina-
tion therewith of a rubber ring formed with a tapered or bevelled edge to fit
against the inside tapered portion or on the top of the neck of the bottle sub-
stantially as and for the purpose hereinbefore described and as shown in Fig. 1
on the drawing.
2. In bottles for containing mineral waters and other fermented or effervescent
liquors or drinks that are stoppered with screw or similar stoppers the combina-
tion of a stopper that is formed with a bevel as c shown in Fig. 2 and flat india
rubber ring whose inner edge converges on said bevel, the flat side
the ring
having a bearing against a bevel formed on the inside of the top of the neck
of the bottle substantially as and for the purpose herein before described.
