JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex,
Gentleman. "IMPROVEMENTS IN APPARATUS FOR DISCHARGING OR DRAWING
LIQUIDS FROM BOTTLES AND SIMILAR RECEPTACLES." A communication from abroad
by Henry Galante, of Paris, in the Republic of France.
This Invention relates to apparatus which the inventor terms "a portable aero-
syphon" for discharging or drawing liquids from bottles and other receptacles.
It is well known that mineral waters are more especially sulphurous waters, such
for example as the waters of Enghien, Bonn, and Aix, deteriorate rapidly as soon
as atmospheric air is allowed to come into contact therewith, consequently it has
been recommended to replace the corks in bottles containing such liquids when such
bottles have been opened for the purpose of discharging a portion of their contents,
and to stand them in an inverted position until required to be again opened. These
precautions however are frequently disregarded, and the bottles are left upright and
uncorked, and even if the cork is replaced it is not effectual in stopping the mouth,
as it is difficult to replace the cork by hand, also on account of the hole necessarily
made by the corkscrew in drawing the cork. Now this Invention has for its object
obviating these inconveniences and to provide means for discharging the liquid from
the bottle in any desired quantities into a glass or other vessel as required, the neck
of the bottle remaining always downwards and covored by the liquid contents
which constitutes an excellent hydraulic obturator. Moreover, the air can never
enter the bottle except at the moment when the liquid is being withdrawn.
In order to effect these objects the mouth of the bottle is provided with a hollow
stopper fitted with a syphon discharge pipe and having an elastic case or covering
for the purpose of making an air tight joint between it and the neck of the bottle
to which it is applied.
Formed in one with or fitted to this stopper is a tube composed of white or
galvanized inetal, or of any rigid material which will not be affected by contact
with the contents of the bottle. This tube is open at its inner end which is
inserted in the bottle to within a short distance of the bottom thereof, whilst its
11

page_text: opposite extremity is closed and projects outside the stopper, and is provided with a
small hole through which air is admitted to the interior of the tube. The inner
end of this tube is closed by a small valve of india rubber, or other suitable material
carried on the inner end of a rod or stem which is passed through the tube, and
which is provided at its enlarged outer end with a button, against which a spiral
spring acts for the purpose of maintaining the valve against the inner end of the
tube. The tube together with the stopper is inserted into the mouth of the bottle,
and the bottle is inverted and placed on a suitable stand in such a manner that the
button on the outer end of the rod or valve stem, herein-before referred to, rests in
a recess formed in the stand.
In order to draw off a portion of the contents of the bottle, sufficient pressure is
exerted on the bottom of the bottle to compress the spiral spring, herein-before
referred to, which will cause the valve on the end of the tube to open, and allow
the air entering by the small hole in the outer end of the tube to rise therein and pass
into the bottle above the liquid. The liquid will then pass into the annular space
between the tube and the interior of the hollow stopper, thence through the syphon
discharge pipe into a glass or other receptacle placed to receive it.
In cases where the liquid contains a large amount of gas, such liquid is prevented
from escaping drop by drop from the end of the syphon, and the proper action of
the apparatus is ensured by providing the syphon pipe with a cock in the syphon,
which should be opened before pressing on the bottom of the bottle.
By means of this apparatus the operation of discharging the contents of the
bottle may be interrupted as often as required, the mineral water or other contents
remaining always well corked when not in use, it being simply necessary to remove
the pressure from the bottom of the bottle, in order to allow the valve to close the
inner extremity of the tube under the action of the spiral spring.
