Improvements in or relating to Apparatus for Withdrawing Liquid
from Bottles and the like.
I, EDOUARD BOLENS, Student of the University of Geneva, Geneva, Switzerland,
do hereby declare the nature of this invention to be as follows:-
The siphons hitherto used for drawing off the liquid contained, say in a bottle, offer
many constructional disadvantages, the two principal ones being that (1) the inlet
holes in the lower part of the main or longer tube very frequently get choked and
thereby stop the working of the apparatus; and (2) the liquid drawn off frequently
contains small particles of cork, making the use of it very unpleasant.
These two drawbacks are entirely obviated in my novel siphon, besides which as
will be seen from the following description various other advantages are inherent in
its construction.
The length of the main hollow tube is variable at will and is provided with a
discharge cock at its upper end. The lower end is provided with a series of small
holes the number of which may also vary as required and through which liquid is
admitted from the bottle to the siphon.
Upon the main tubo is fitted a tube herein termed the "cork-screw tube" because
exteriorly it is formed with a thread to enable it to be screwed into a cork or
equivalent stopper. The point of the cork-screw is formed on the main tube. This
cork screw tube slides on the main tube in rather close frictional contact therewith
and from the handle or upper part of the said cork-screw tube a small branch projects
laterally. To this branch is fitted an india-rubber ball by the compression of which
air is forced into the siphon. A washer of india-rubber or any other suitable material
is provided so as to form an air-tight packing, or closing device, to prevent the air
forced in by means of the india-rubber ball from escaping upwardly. On the inside
of the cork-screw tube where it comes in contact with the main tube a number of
longitudinal grooves are provided for the passage of the air issning from the india-
rubber ball. This enables the inner diameter of the cork-screw tube to be equal to
the outer diameter of the main tube whereby although no
play can take place,
the cork screw tube can readily slide up and down the main tube, whilst on the other
hand the air passing through the said grooves forces the liquid upward.
<<
"
It will also be understood that as the cork-screw tube is always in its lowest end
position on the main tube when it is screwed through the cork of a bottle, the
orifices in the main tube are effectively prevented from admitting any particles of
cork into the siphon tube. After the cork is perforated the main tube is lowered
down to the bottom of the vessel. The air supplied by the india-rubber ball travels
along the grooves and always escapes into the bottle below the cork or stopper, so
that in no case can any fragments of cork get mixed with the liquid. The main tube
is provided with no opening at its surface other than those at its lower end, and
inasmuch as the extent which the cork-screw is allowed to travel on the main tube
may be limited at will, my apparatus is applicable to bottles or vessels of any desired
height or length.
When very gaseous liquids are to be transferred from one vessel to another, the
indiarubber ball or any other means of forcing in air by pressure, as well as the inner
grooves of the cork-screw tube are dispensed with. In that case the discharge cock
may also be replaced by an ordinary siphon lever as used for Seltzer water. My
apparatus may also be used for producing sprays for medical purposes, or for scent,

page_text: disinfecting liquids, mineral waters &c. for which purpose it will be sufficient to use
a suitable spray producer instead of the before mentioned cock.

COMPLETE SPECIFICATION.
Improvements in or relating to Apparatus for Withdrawing Liquid
from Bottles and the like.
I, EDOUARD BOLENS, of the University of Geneva, Geneva, Switzerland, Student,
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:-
The siphons hitherto used for drawing off the liquid contained say in a bottle offer
many structural disadvantages the two principal ones being that (1) the inlet holes
in the lower part of the main or longer tube very frequently get choked and thereby
stop the working of the apparatus and (2) the liquid drawn off frequently contains
small particles of cork making the use of it very unpleasant.
These two drawbacks are entirely obviated in my novel siphon, besides which as
will be seen from the following description various other advantages are inherent in
its construction.
In the accompanying drawing,
Fig. 1 is an elevation of the complete device and
Fig. 2 an elevation of the lower end of the main tube.
Fig. 3 shows an india-rubber ball as applied to the device.
A, Fig. 1 is the main hollow tube the length of which is variable at will and is
provided with a discharge cock R at its upper end. The lower end is provided with
a series of small holes the number of which may also vary as required and through
which liquid is admitted from the bottle to the siphon a detail view of this end and its
orifices is given in Fig. 2 which also shows the lower portion of the cork-screw thread
forming a solid and pointed end to the tube A.
This cork-screw tube B slides on the main tube A in rather close frictional contact
therewith and from the handle or upper part of the said cork-screw tube a small
branch Fig. 1 projects laterally. To this branch is fitted an india-rubber ball P
Fig. 3 by the compression of which air is forced into the siphon. d is a washer of
india-rubber or any other suitable material provided so as to form an air-tight packing
or closing device to prevent the air forced in by means of the india-rubber ball P
from escaping upwardly. On the inside of the cork-screw tube where it comes in
contact with the main tube A a number of longitudinal grooves are provided for the
passage of the air issuing from the india-rubber ball. This enables the inner diameter
of tube B to be equal to the outer diameter of tube A whereby although no "play"
can take place the tube B can readily slide up and down the tube A, whilst on the
other hand the air passing through the said grooves forces the liquid upward.
وو
It will also be understood that as tube B is always in its lowest end position on the
main tube A when it is screwed through the cork of a bottle the orifices a are
effectively prevented from admitting any particles of cork into the siphon tube. After
the cork is perforated the tube A is lowered down to the bottom of the vessel, so that
the wormed tube B assumes the position B'. It will be seen that the air supplied by the
india-rubber ball travels along the grooves and always escapes into the bottle below
the cork or stopper C, so that in no case can any fragments of cork get carried along
with the liquid. The tube A is provided with no opening at its surface other than
those at its lower end a, and inasmuch as the extent which tube B is allowed to travel
ou tube A may be limited at will my apparatus is applicable to bottles or vessels of
any desired height or length.
In cases where the liquid to be drawn is more or less liable to be affected by the

page_text: oxygen of the air the air admitting device and india-rubber ball may be replaced by
a modified arrangement. Instead of air some inert gas such as nitrogen or carbonic
acid may be used and the arrangement for introducing it into the bottle is as
follows:-
The cork-screw tube Fig. 1 is provided with a reservoir R¹ Fig. 4 of spherical,
elliptical or other shape at the top of which an opening is provided which affords
ready access for the substances the re-action of which is to result in the generation of
the required gas. A runner D screwing on the rod A¹ Fig. 4 serves the purpose of શ
stopper and enables the reservoir to be opened or closed at will, and with a view to
rendering such closing perfectly air-tight the said runner is fitted with an india-rubber
or other washer of a diameter somewhat larger than the opening in the reservoir R'.
By this means the whole of the gas produced within R' is directed towards the liquid
to be transferred in the same way as is the air forced in by means of the rubber ball
in the first mentioned arrangement. Supposing for example that carbonic acid is to
be employed for the purpose, a suitably proportioned mixture of bicarbonate of soda,
tartaric acid and water is placed in the reservoir.
It will be understood that the reservoir R¹ may be constructed of any material that
is proof against the action of the chemicals used in bringing about the reaction.
When very gaseous liquids are to be transferred from one vessel to another the
india-rubber ball or any other means of forcing in air by pressure as well as the
inner grooves of tube B are dispensed with. In that case the discharge cock R may
also be replaced by an ordinary siphon lever as used for Seltzer water. My apparatus
may also be used for producing sprays for medical purposes or for scent, disinfecting
liquids mineral waters &c. for which purpose it will be sufficient to use a suitable
spray producer instead of cock R.
The main advantages of the apparatus herein described may be summed up as
follows:-
Particles of cork are prevented from obstructing the siphon or falling into the
liquid; the closing is entirely air-tight; the liquids acted upon are in no case injured
or spoilt, and lastly the operation of the apparatus is exceedingly easy owing to the
circumstance that the strain is applied in close proximity to the point of resistance.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. An improved "siphon” or pump substantially as described and illustrated in the
accompanying drawings.
2. In an apparatus such as described the combination with a tube such as A having
a pointed threaded and solid tip and perforations above the tip of an outer tube such
as B perforated and grooved substantially as and for the purpose described and
illustrated in the accompanying drawings.
3. The employment of a reservoir such as R¹ for the production of an inert gas
when it is required to exercise pressure upon a liquid liable to be affected by the
oxygen of the air substantially as described and illustrated in the accompanying
drawings it being understood that the air or gas which is to force the liquid up the
siphon may be produced by any means or derived from any source other than that
indicated.
4. The tube B constructed as described and provided with a screw thread which
may if necessary be somewhat conical in shape the broader end or base of the cone
being placed at the top substantially as described and illustrated in the accompanying
drawings.
