Im- PROVEMENTS IN BOTTLES AND STOPPERS FOR AERATED LIQUIDS
Year: 1874

page_text: LETTERS PATENT to Edmund Hunt, of Glasgow, in the County of
Lanark, North Britain, Patent Agent, for the Invention of “Im-
PROVEMENTS IN BOTTLES AND STOPPERS FOR AERATED LIQUIDS."-A com-
munication from abroad by George Gledhill, residing at Auckland,
New Zealand.
PROVISIONAL SPECIFICATION left by the said Edmund Hunt at the
Office of the Commissioners of Patents, with his Petition, on the
24th February 1874.
"
I, EDMUND HUNT, of Glasgow, in the County of Lanark, North
Britain, Patent Agent, do hereby declare the nature of the said In-
vention for “IMPROVEMENTS IN BOTTLES AND STOPPERS FOR ÅERATED LIQUIDs,”
(which Invention has been communicated to me from abroad by George
Gledhill, residing at Auckland, New Zealand) to be as follows, that is
to say :-
This Invention has for its object the forming and arranging of bottles
Jstonners for nerated liquids so as in a better and more satisfactory

page_text: manner than heretofore to dispense with the use of corks and wires, and
render the operation of filling and discharging the bottles expeditious
and convenient.
In carrying out the Invention the body of the bottle may be of any
convenient shape, but is by preference nearly cylindrical, being slightly
tapered from the base towards the outlet end. The outlet is a short
thickened nozzle formed immediately on the shoulder or end of the
body without the intervening elongated neck, which weakens the
common form of bottle, and at the same time unnecessarily occupies
space. The stopper is a ball or sphere of rubber, which is made of a
suitable density or is weighted so that it will sink easily in the liquid
when otherwise free to do so. A suitable density for the stopper ball is
such as will cause it to sink easily in castor oil at ordinary temperatures.
The nozzle of the bottle is spherically shaped internally, so that the
stopper ball may lodge in it against an ample surface, which is a counter-
part of its own form, and not liable to alter the shape or produce
indentations or ribs on it by the action of the internal pressure. The
bottle is internally shaped at the shoulder so that a section through the
-axis of the bottle at that part presents a part of a circle corresponding
to about a quarter of the circumference of the stopper ball, and when
the contents of the bottle are being poured out the stopper ball rests on
the concavity of the shoulder, and is not so liable as in the common
form to get into the outlet and interrupt the discharge. The stopper
ball is forced in through the contracted orifice of the outlet, which
operation may be facilitated by pushing it through a tapered tube.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Edmund Hunt in the Great Seal Patent Office on
the 22nd August 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDMUND
HUNT, of Glasgow, in the County of Lanark, North Britain, Patent 3
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent bearing date the Twenty-fourth day of February; in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-

page_text: seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edmund Hunt, Her special licence that
I, the said Edmund Hunt, my executors, administrators, and assigns, or
such others as I, the said Edmund Hunt, my executors, administrators,
and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein.
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for “ IMPROVEMENTS IN BOTTLES
AND STOPPERS FOR AERATED LIQUIDS," (a communication to me from abroad
by George Gledhill, residing at Auckland, New Zealand) upon the con-
dition (amongst others) that I, the said Edmund Hunt, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Edmund Hunt, do hereby declare the
nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement in writing, reference being had to the accompanying
Drawings, that is to say :-
The said Invention has for its object the forming and arranging of
bottles and stoppers for aerated liquids so as in a better and more satis-
factory manner than heretofore to dispense with the use of corks and
wires, and render the operation of filling and discharging the bottles
expeditious and convenient.

.
In carrying out the Invention the body of the bottle may be of any
convenient shape, but is by preference nearly cylindrical. The outlet is
a short thickened nozzle formed immediately on the shoulder or end of
the body without the intervening elongated neck, which weakens the
common form of bottle, and at the same time unnecessarily occupies
space. The stopper is a ball or sphere of rubber, which is made of a
suitable density or is weighted so that it will sink casily in the liquid
when otherwise free to do so. A suitable density for the stopper ball is
such as will cause it to sink easily in castor oil at ordinary temperatures.

page_text: The nozzle of the bottle is spherically shaped internally so that the
stopper ball may lodge in it against an ample surface, which is a counter-
part of its own form, and not liable to alter the shape or produce
indentations or ribs on it by the action of the internal pressure. The
bottle is internally shaped at the shoulder so that a section through the
axis of the bottle at that part presents a part of a circle corresponding
to about a quarter of the circumference of the stopper ball, and when
the contents of the bottle are being poured out the stopper ball rests in
the concavity of the shoulder, and is not so liable as in the common form
to get into the outlet and interrupt the discharge. The stopper ball is 1
forced in through the contracted orifice of the outlet, which operation
may be facilitated by pushing it through a tapered tube with a mandril
or by means of water under pressure.
And in order that the said Invention and the manner of performing
the same may be properly understood I hereunto append a Sheet of 1
explanatory Drawings, Figure 1 thereof being a vertical section of the
improved bottle and stopper for aerated beverages, and showing the
stopper ball in the closing position in which it is held by the gas.
Figure 2 is a section showing the nozzle of the bottle as first formed
in the mould when made of glass. The bottle thus far formed is held in 2
a cup-shaped pontee or holder and the nozzle is heated, and a ring of
metal being added to it, if necessary, is brought to the shape shown in
Figure 1 by means of a hand tool similar to that in common use for
shaping bottle mouths.
Figure 3 is a section of the bottle in the inclined position for pouring 2
out the contents, and shows how the stopper ball is retained by the
shoulder, and is on that account less liable to close the mouth when not
desired than in soda water bottles of the common form.
Having thus particularly described the said Invention, and the
manner of performing the same, I have to state that I do not claim as a
new the general application of an internal stopper held close by the
pressure within the bottle, but that what I believe to be novel and
original and claim as the Invention communicated to me by the said
George Gledhill, and secured to me by the herein-before in part recited
Letters Patent is,-
1. The application and use of a spherical stopper of rubber in com-
bination with an internal spherical seat in bottles for containing aerated

page_text: liquids, the stopper being of such a density as to sink in the liquid, sub-
stantially as herein-before described.
2. The forming of a bottle for aerated liquids, and for being closed
with an internal spherical stopper, with a hollow shoulder, substantially
as and for the purpose herein-before described.
In witness whercof, I, the said Edmund Hunt, have hereunto
set my hand and seal, this Twenty-first day of August, in the
year of our Lord One thousand eight hundred and seventy-
four.
