in the County of Middlesex, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR FILLING BOTTLES WITH AERATED LIQUIDS."

the Office of the Commissioners of Patents on the 15th July 1879.
FREDERICK GEORGE RILEY, of Buckingham Palace Road, in the County of
Middlesex. IMPROVEMENTS IN APPARATUS FOR FILLING BOTTLES WITH AERATED
LIQUIDS."
<s
My Invention relates to apparatus for filling with aerated liquids bottles to be
closed with internal stoppers. Heretofore apparatus of this description has usually
been constructed with an air tube, which is forced into the inverted bottle when it
is to be filled, and through which air tube the air compresed by the entering liquid
escapes as soon as the pressure of the confined air is sufficient to open a weighted
valve with which the pipe is provided. According to this arrangement, however,
when the tube is withdrawn in order to admit of the stopper falling into the mouth
of the bottle a portion of the aerated liquid escapes through the valve which still
remains open.
Now, according to my Invention, I employ a valve, which is normally maintained
closed by a spring or its equivalent, and I provide tappets so arranged that by the
act of forcing the air tube into the bottle the valve will be opened for the escape
of air, whilst as the tube is withdrawn when the bottle is filled the valve will close
automatically under the action of the spring or its equivalent, thus preventing the
escape of any liquid from the bottle. I prefer to suspend the supply of the liquid
when the air is to be discharged, and then add a further quantity of liquid suf-
ficient to take the place of the compressed air as soon as the latter has been
expelled.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Frederick George Riley in the Great Seal Patent Office on the 15th
January 1880.
FREDERICK GEORGE RILEY, of Buckingham Palace Road, in the County of
Middlesex. " IMPROVEMENTS IN APPARATUS FOR FILLING BOTTLES WITH AERATED
LIQUIDS."
My said Invention relates to apparatus for filling with aerated liquids bottles to
be closed with internal stoppers. Heretofore apparatus of this description has

page_text: usually been constructed with an air tube, which is forced into the inverted bottle
when it is to be filled, and through which air tube the air compressed by the
entering-liquid-escapes as soon as-the-pressure-of_the_confined_air_is_sufficient to
open a weighted valve with which-the pipe is provided; the disadvantage of this
arrangement is that when the tube is being withdrawn in order to admit of the
stopper falling into the mouth of the bottle a portion of the aerated liquid-escapes.
through the valve, which still remains open. Now, according to my said Inven-
_tion, I employ a valve which is normally maintained closed by a spring or its
equivalent assisted by the air pressure, and I provide tappets so arranged that by
_the act of forcing the air tube up to the top of the inverted bottle the valve will
-be opened for the escape of the air, and as the tube is being withdrawn from the
top the valve will close automatically.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same, and for that purpose shall refer to
the accompanying Drawing, which represents a vertical section of so much of an
apparatus for filling bottles as is necessary to illustrate my said Invention.
A is a portion of an air tube to be inserted in a bottle to be with aerated
liquid; B is a valve which is maintained closed by a spring b or its equivalent;
and C is a tappet or fixed piece with which the elongated portion of the valve
guide b' comes in contact in the act of inserting the air tube in the bottle.
The apparatus operates in the following manner :-
The air tube A is forced upwards into the inverted bottle to be filled with liquid
until the valve guide 6' comes in contact with the tappet or fixed piece C, thereby
compressing the spring band opening the valve B so as to admit of the escape of
the compressed air from the bottle. The said valve remains open so long as the air
tube A is at this height within the bottle, this particular height being so regulated
with regard to the position of the tappet C that when the valve guide strikes the
said tappet the top of the air tube is at the top of the inverted bottle, that is to
say, within the air space.
Upon withdrawing the air tube A from the top of the bottle, and consequently
the valve guide from the tapper, the valve is closed automatically by the action of
the spring bor its equivalent, thus preventing the escape of any liquid from the
bottle.
I prefer to suspend the supply of the liquid when the air is to be discharged, and
then add a further quantity of liquid sufficient to take the place of the compressed
air as soon as the latter has been expelled.
Having now described and particularly ascertained the nature of my said In-
vention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider to be novel and original,
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent is,-
In apparatus for filling bottles with aerated liquids the combination with the-air-
tube of a valve which is normally maintained closed, and is arranged so as to
operate substantially in the manner and for the purpose hereinbefore described.
In witness whereof, I, the said Frederick George Riley, have to this my
Specification set my hand and seal, this Fourteenth day of January, One
thousand eight hundred and eighty.
