page_text: LETTERS PATENT to Edward William Grimwade, of 82, Bishopsgate Street
Within, in the City of London, Merchant, for an Invention of " IMPROVE-
MENTS IN STOPPERING BOTTLES FOR CONTAINING AERATED OR GASEOUS
LIQUIDS." A communication from abroad by Alfred Felton and Frederick
Sheppard Grimwade, both of Melbourno, Victoria, Australia.
PROVISIONAL SPECIFICATION left by the said Edward William Grimwade
at the Office of the Commissioners of Patents on the 6th January 1880.
EDWARD WILLIAM GRIMWADE, of 82, Bishopsgate Street Within, in the City of.
London, Merchant. "IMPROVEMENTS IN STOPPERING BOTTLES FOR CONTAINING
AERATED OR GASEOUS LIQUIDS." [A communication from abroad by Alfred Felton
and Frederick Sheppard Grimwade, both of Melbourne, Victoria, Australia.]
The Invention communicated to me relates to improvements in stoppering that
class of bottles used for containing aërated or gaseous liquids in which the stop-
pering is effected by means of an internal stopper of spherical or other suitable
shape, which is forced and held against an elastic seating in the neck of the
bottle.
In carrying out the Invention the bottle is formed with an annular groove or
chamber in the top of the neck, and the ball or other shaped stopper being passed
into the bottle a ring of vulcanized india rubber or other suitable elastic material
is fitted in the said annular groove or chamber, and to keep the said ring from
being forced out of the bottle a cap or capsule of soft metal is employed, the lower
edge of which is turned over a ledge formed on the outside of the neck of the
bottle. The centre of the top of the capsule is open to allow of the filling of the
bottle and the discharge of the contents when the bottle is opened.
By this arrangement a small portion only of the elastic seating will be exposed
to contact with the liquid contained in the bottle. The bottles may be manu-
factured economically, and the fitting up of the same with the stoppering arrange-
ment may be simply and quickly effected, and will be little liable to get out of
order.

EDWARD WILLIAM GRIMWADE, of 82, Bishopsgate Street Within, in the City of
London, Merchant. "IMPROVEMENTS IN STOPPERING BOTTLES FOR CONTAINING
AERATED OR GASEOUS LIQUIDS." A communication from abroad by Alfred Felton
and Frederick Sheppard Grimwade, both of Melbourne, Victoria, Australia.
The Invention communicated to me relates to improvements in stoppering that
class of bottles used for containing aërated or gaseous liquids in which the stop-
pering is effected by means of an internal stopper, which is circular in its horizontal
section, and which is forced and held against an elastic seating in the neck of the
bottle.
·
In carrying out the Invention the bottle is formed with an annular groove or
chamber in the top of the neck, and the ball or other shaped stopper being passed
into the bottle a ring of vulcanized india rubber or other suitable elastic material
is fitted in the said annular groove or chamber, and to keep the said ring from
being forced out of the bottle a cap or capsule of soft metal is employed, the lower
edge of which is turned round a shoulder formed on the outside of the neck of the
bottle. The centre of the top of the capsule is open to allow of the filling of the
bottle and the discharge of the contents when the bottle is opened.
But to make the Invention communicated to me better understood I will now
describe the same by reference to the accompanying Drawing, in which Figure 1
is a sectional elevation of the neck of a bottle stoppered according to this Invention,
and Figure 2 is a plan of the same. Similar letters in both Figures represent
similar parts.
a is the annular groove or chamber in the top of the neck b of the bottle; c is
the stopper; d is the ring of vulcanized india rubber or other suitable elastic
material fitted in the said annular groove or chamber a; e is the cap or capsule of
soft metal, the lower edge of which is turned round the shoulder formed on the
outside of the neck b of the bottle.
By this arrangement a small portion only of the elastic seating d will be exposed
to contact with the liquid contained in the bottle. The bottles may be manu-
factured economically, and the fitting up of the same with the stoppering arrange-
ment may be simply and quickly effected, and will be little liable to get out of
order.
Having thus described the Invention communicated to me, and the best means
with which I am acquainted for carrying the same into effect, I wish it to be
understood that what is claimed and intended to be protected by the herein in part
recited Letters Patent is,-
The combination of the capsule and the india rubber ring in the annular chamber
with stoppers which are circular in their horizontal section, as hereinbefore
described and represented in the accompanying Drawing.
In witness whereof, I, the said Edward William Grimwade, have hereto set
my hand and seal, this Second day of July, in the year of our Lord One
thousand eight hundred and eighty
