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 PACKING RINGS AND DISCS USED FOR OBTAINING A TIGHT JOINT BETWEEN THE
"3 to be as
MOUTH OF A BOTTLE OR JAR AND THE STOPPER WHICH CLOSES IT
follows:-
This Invention has for its object improvements in packing rings and discs used
for obtaining a tight joint between the mouth of a bottle or jar and the stopper
which closes it.
For this purpose I form such rings or discs from a sheet or sheets of cork
cemented on to one or both sides of a sheet of vulcanized india rubber; the rings
or discs I cut to the size required from such compound sheet by suitable cutting
punches or tools.
Rings made in this way may be used for inserting into a groove formed around
the interior of the mouth of a bottle either for a glass ball to rest against as
described in the specification of a former Patent granted to me in the year 1870
N° 3070 or for other forms of stoppers whether internal or external stoppers to
bear or rest against or the rings may be inserted into grooves formed in other
positions around the head of a bottle either for external caps or stoppers or for
internal stoppers to bear against, or discs or rings cut from the sheet might be
carried by screw caps to be screwed on to the beads of bottles or be carried by
whatever other form of stopper may be used.

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 packing rings and discs used
for obtaining a tight joint between the mouth of a bottle or jar and the stopper
which closes it.
For this purpose I form such rings or discs from a sheet or sheets of cork
cemented on to one or both sides of a sheet of vulcanised india rubber; the rings
or discs I cut to the size required from such compound sheet by suitable cutting
punches or tools.
Rings made in this way may be used for inserting into a groove formed around
the interior of the mouth of a bottle, either for a glass ball to rest against, as
described in the specification of a former Patent granted to me in the year 1870
N° 3070 or for other forms of stoppers whether internal or external stoppers to
bear or rest against or the rings may be inserted into grooves formed in other
positions around the head of a bottle either for external caps or stoppers or for
internal stoppers to bear against, or discs or rings cut from the sheet might be
carried by screw caps to be screwed on to the heads of bottles or be carried by
whatever other form of stopper may be used.
I make no alteration in the form of the packing rings and discs now in use but
in place of cutting them out from shect india rubber of appropriate thickness
I prepare a compound sheet of like thickness.
For soda water bottles and the like I make the compound sheet of two sheets of
equal thickness the one of cork and the other of vulcanised india rubber. I cement
the two together with ordinary waterproof cement. After allowing the cement
to dry perfectly I cut out the rings or discs required with proper punches or tools.
Where rings have to be inserted into a groove or cavity I thoroughly soften them
by heat and moisture before performing this operation.
In cases where it is desirable to cover both the faces of the vulcanised india
rubber with cork as for stoppers for jars to contain pickles and like materials
which more or less injure the india rubber I prefer that the cork should be of
about half the thickness of the india rubber so that in the finished ring or disc
half may be india rubber and the other half cork the cork being divided and
forming an inalterable face to the india rubber on either side.

page_text: By the use of such compound rings or discs I retain all the advantages due to
the use of india rubber, its elasticity and impermeability whilst at the saine time
I protect the contents of the bottle or vessel from contact with the india rubber.
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
Packing rings and discs serving to form a tight joint between the mouth of a
bottle or jar and the stopper which closes it such packing rings or discs being
formed from sheet cork and vulcanised india rubber sheet cemented together.
