PROVISIONAL SPECIFICATION.
Improved Appliance or Device for Starting Siphons to Work.
I, PAUL MICHEL, of 16, Rue Drouot, Paris, in the Republic of France, Doctor,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object an appliance or device for starting siphons to
work without having to use the mouth or otherwise to create a suction; it will
therefore be specially applicable in the case of medicinal liquids, or chemical
products, where it is dangerous to use the mouth, or even to touch such liquids in
order to start the siphon by immersing it, as is frequently done.
This appliance or device is composed of a metallic tube or its equivalent, having
at its upper end two rollers adjustable towards one another so as to bring them
almost into contact and compressing between them the tube of india rubber or
other elastic and supple material which forms the siphon. When this has been
done if the appliance or device be drawn downwards, the india rubber tube
is flattened between the rollers driving back the air which it contains and forming
consequently an almost perfect vacuum behind it, the result of which is a suction
of the liquid into which the opposite end of the tube is inserted, and consequently
the siphon will start to work.
The same apparatus may also serve as a tap when the siphon is drawing, in fact the
rollers may be completely approached one to the other so as to entirely arrest the
flow of the liquid, or only be approached more or less so as to regulate the delivery
of the siphon as may be required.
Any suitable means of adjusting the rollers may be employed, for instance, one
of them may be in fixed bearings whilst the other may rest in a little curved
cushion and be brought up to the fixed roller by a little spindle and thumb screw.

COMPLETE SPECIFICATION.
Improved Appliance or Device for Starting Siphons to Work.
I, PAUL MICHEL of 16 Rue Drouot, Paris, in the Republic of France Doctor,
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 :-
This invention has.for its object an appliance or device for starting siphons to
work without having to use the mouth or otherwise to create a suction; it. will
therefore be specially applicable in the case of medicinal liquids, or chemical
products, where it is dangerous to use the mouth, or even to touch such liquids in
order to start the siphon by immersing it, as is frequently done.
This appliance or device is composed of a metallic tube or its equivalent, having
at its upper end two rollers adjustable towards one another in such a way as to
bring them almost into contact and compressing between them the tube of india
rubber or other elastic and supple material which forms the siphon. When this
has been done, if the appliance or device be drawn downwards, the india rubber
tube is flattened between the rollers, driving back the air which it contains and
forming consequently an almost perfect vacuum behind it, the result of which is a
suction of the liquid into which the opposite end of the tube is inserted, and
consequently the siphon will start to work.

page_text: In order to enable this invention to be better understood, reference will now be
made to the accompanying drawing, ou which :-
Figure 1 is a sectional elevation of this apparatus when at work:
Figure 2, an elevation of the same apparatus when it is not being used: and
Figure 3, a side view of the same, taken on the left hand side of Figure 2.
R is the reservoir containing the liquid which it is desired to draw off by means
of the siphon T, formed of a tube of indiarubber or other suitable elastic material,
which, at the bend, has a rigid metal or other casing t. Around the siphon tube
I place a suitable tube of metal or other resistant material T' which has two
rollers a a', one of which, a', is fixed, and the other, a, is connected to a movable
adjusting piece & which may be easily moved by hand, for instance, by means of
the knob ; thus, if desired, the roller a may be moved away from the roller a¹,
Figures 2 and 3, so as to allow the indiarubber tube to assume its natural shape, or,
on the contrary, it may be brought almost in contact with the other roller, as
shown in Figure 1. If, when in this position, the apparatus be drawn downwards,
the siphon tube will slip between the rollers, causing them to revolve, whilst
remaining flattened by them, which forces out in front the air contained in the
tube, the result of which is to form, in the tube behind the apparatus, a partial
vacuum which will be sufficient to cause the siphon to draw, and consequently to
exhaust, the liquid in the reservoir R.
The same apparatus may also serve as a tap when the siphon is drawing, in fact
the rollers may be completely approached one to the other so as to entirely arrest
the flow of the liquid, or only be approached more or less so as to regulate the
delivery of the siphon as may be required.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
An improved appliance or device for starting siphons to draw and enabling
their delivery to be regulated at will, consisting of a metallic tube having at its
upper end two rollers which may be made to approach by means of a suitable
mechanism so as to bring them almost or entirely in contact with one another,
in such a way as to compress between them the elastic and flexible tube which
forms the siphon; substantially as hereinbefore described and shown on the
accompanying drawing.
