Aërated or Gaseous Liquids.
I JOHN JAMES VARLEY of Phoenix Villas Merton in the County of Surrey
Engineer do hereby declare the nature of my said invention for "IMPROVEMENTS
IN SEATINGS FOR STOPPERS FOR BOTTLES CONTAINING AËRATED OR
LIQUIDS" to be as follows:-
GASEOUS
This invention relates to improvements in that class of seatings or rings which
are placed in the necks of bottles for the purpose of forming a gas tight joint for
the stoppers of such bottles whereby the liability of the stoppers being forced out
by the pressure of the gas within the bottle is prevented and the seating or ring
is firmly fixed in its place so that it cannot be displaced or blown out.
In carrying out my invention I form a ring or core of hemp, flax, silk, cotton, or
other suitable fibrous material and I coat or cover the said ring or core with soft
india rubber and form the same of the required shape so that it can be fitted into
the usual groove made in the neck of the bottle.
.
I sometimes make the core of the said ring or seating of wire coiled into a
spiral or other suitable form so that it can be compressed or bent to allow of its
being fitted into the groove in the neck of the bottle or other materials of a flexible
nature may be used to form the core. In some cases I may only partially cover
the said core with india rubber,

I JOHN JAMES VARLEY of Phoenix Villas, Merton, in the county of Surrey,
Engineer, do hereby declare the nature of my said invention for “IMPROVEMENTS
IN SEATINGS FOR STOPPERS FOR BOTTLES CONTAINING AERATED OR GASEOUS
LIQUIDS" 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 improvements in that class of seatings or rings whieh
are placed in the necks of bottles for the purpose of forming a gas tight joint for
the stoppers of such bottles, whereby the liability of the stoppers being forced out
by the pressure of the gas within the bottle is prevented, and the seating or
ring is firmly fixed in its place so that it cannot be displaced or blown out.
In carrying out my invention a ring or core of hemp, flax, silk, cotton, or other
suitable fibrous material is coated or covered with soft india rubber and the same
is formed of the required shape so that it can be fitted into the usual groove made
in the neck of the bottle.
In order to enable my invention to be fully understood and carried into practice
I will proceed to describe by reference to the accompanying drawing the method
I find most suitable for manufacturing seatings or rings of vulcanized india rubber
with a core of suitable material such as flax.
From sheet rubber dough, of the required thickness, I cut in any suitable
manner, a number of strips or pieces, each of the proper size to form a ring or
seating. One of these strips or pieces a, is then laid around a rod or mandril such
as b, as shewn in figure 1 of the drawing; the ends of the soft rubber dough are
joined by being pressed together so as to form a short tube. Around the periphery
of this short tube a, I then wind hempen string or other suitable fibre c, as shewn
in figure 2 of the drawing to form a core; the said hempen string or other fibre
is coated with india rubber in solution so as to insure its adhering to the rubber
tube a; the ends of the india rubber tube a, are then turned over the hempen
string core c, and the edges joined and fastened together as shewn in the partly
sectional view at figure 3. The ring of rubber dough thus formed is then removed
from the rod or mandril and placed in a die and finished or cured in the manner
usually practised in manufacturing. vulcanized india rubber. Or the use of a die
can be dispensed with and the ring be cured in chalk, or in other well known
manner. Figure 4, is a section, and figure 5, a plan of the finished seating
or ring.
I thus obtain elastic rings or seatings suitable for insertion in the grooves
usually formed in the necks of bottles closed with internal stoppers; such rings
or seatings are very flexible and can be easily inserted into the said grooves but,
by reason of the core with which the rings or seatings are provided not being
elastic, their diameter cannot be increased, thereby preventing the seatings being
displaced and the stoppers (which are placed in the bottles before the seatings) from
being blown out by the internal pressure within the bottle.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is
1. The manufacture of seatings for insertion in grooves in the necks of bottles
having internal stoppers, from vulcanized india rubber with a core of hemp or
other like material, substantially as and for the purposes hereinbefore described.
2. The use, with bottles having internal stoppers, of the improved seatings
herein before described and represented in the accompanying drawing,
