I HIRAM CODD of N° 41 Gracechurch Street in the City of London Bottle
Manufacturer do hereby declare the nature of my invention for "IMPROVEMENTS
IN STOPPERING OR CLOSING BOTTLES FOR CONTAINING AERATED LIQUIDS" to be as
follows:-
This Invention bas for its object improvements in stoppering or closing bottles
for containing aerated liquids.
For this purpose I form the bottle with a screw thread around the interior of
the head and with a ledge projecting inwards all around the inner end of the
screw thread for an elastic washer to rest on as is described in the Specification of
a Patent granted to Sykes and Macvay N° 738 in the year 1877 and this elastic
washer I hold down to the ledge by the lower end of a screw tube or ferule
screwed into the screw thread in the neck as described in that Specification or it
might be held down on to the ledge by a metal ring held in other ways into the
mouth of the bottle Before the elastic ring is inserted into its place within
the mouth of the bottle I drop into the interior of the bottle a disc of strong tough
material preferably of glass or a compound now commonly employed as a substitute
for ivory but it might be of any strong tough material which would not be
affected by the liquid to be contained in the bottle-The ring of elastic material
is then put into place and secured as above described-The inner diameter of the
elastic ring is smaller than the diameter of the disc so that when the disc lies
across the mouth of the bottle its edges may overlap and rest upon the inner edge
of this ring-The inner diameter of the metal ring placed above the elastic ring is
also smaller than the diameter of the disc so that the disc cannot possibly be forced
outwards from the mouth of the bottle.

Improvements in Stoppering or Closing Bottles for Containing
Aerated Liquids.
I, HIRAM CODD of No 41 Gracechurch Street in the City of London Bottle
Manufacturer 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 has for its object improvements in stoppering or closing bottles
for containing aerated liquids.
For this purpose I form the bottle with a screw thread, around the interior of
the head and with a ledge projecting inwards all around the inner end of the
screw thread for an elastic washer to rest on as is described in the specification of
a Patent granted to Sykes and Macvay No 738 in the year 1877 and this elastic
washer I hold down on to the ledge by the lower end of a screw tube or ferrule
screwed into the screw thread in the neck as described in that specification or it
might be held down on to the ledge by a metal ring held in other ways into the
mouth of the bottle. Before the elastic ring is inserted into its place within
the mouth of the bottle I drop into the interior of the bottle a disc of strong
tough material preferably of glass or any compound now commonly employed as a
substitute for ivory but it might be of any strong tough material which would not
be affected by the liquid to be contained in the bottle. The ring of elastic matorial
is then put into place and secured as above described. The inner diameter of the
elastic ring is smaller than the diameter of the disc so that when the disc lies
across the mouth of the bottle its edges may overlap and rest upon the inner edge
of this ring. The inner diameter of the metal ring placed above the elastic ring is
also smaller than the diameter of the disc so that the dise cannot possibly be forced
outwards from the mouth of the bottle.
The drawing annexed shews a vertical section of the head of a bottle A closed in
the above manner.
A¹ is the screw thread formed around the interior of the head. B the ledge
formed at the lower end of this screw. thread. C the elastic ring which is made to
rest on this ledge. D the tube or ferrule screwed into the screw thread in the
head so that its lower end comes down on to and holds the elastic ring. D' is a
small projection standing out from the interior of the tube or ferrule to fit into
a corresponding hollow in the key used for screwing the tube or ferrule into or out
of place. E is the disc shaped stopper formed preferably of glass.
I would state that I am aware that disc shaped stoppers have before been used
for closing the mouths of bottles for containing aerated liquid but when such
stoppers have been used they have heretofore been made to bed against an elastic
ring held in an annular groove formed around the interior of the head and they
have been inserted into the bottle by forming vertical grooves down the inside of
that portion of the head which is above the groove so that the disc which is
of larger diameter than this portion of the head of the bottle may be slipped in
edgewise.

page_text: I avoid as above described the necessity of forming such vertical grooves in thé
interior of the head of the bottle through which leakage is very apt to take place.
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 stoppering or closing of bottles for containing aerated liquids substan-
tially in the manner herein before described.
2. The combination of a disc stopper E with a bottle A having a screw
thread A moulded around the interior of its head and a ledge B at the end of the
screw thread and also an elastic ring C placed on the ledge and held down to it by
a tube or ferrule D screwed into the screw thread.
