LÉON VALLET, of Liverpool, in the County of Lancaster. IMPROVEMENTS IN
AND RELATING TO 'SYPHONS' FOR AERATED OR GASEOUS BEVERAGES AND
LIQUIDS."
This Invention relates to certain improvements on the well known high pressure
syphon bottle for containing aërated or gaseous beverages and liquids, and has for its
object the reduction or checking of the force with which aerated or gaseous
beverages, or liquids from ordinary syphon bottles are generally discharged, the
force of the discharge being arrested within the syphon bottle; further, a great
saving by the retention of the gas in the bottle is effected. The liquid drawn off
also retains its gaseous state for a longer period than is the case with liquids drawn
from the common syphon.
According to the usual construction of syphons for gaseous or aerated liquids no
particular attention is given to the fact that the syphon tube should be smaller in
internal diameter than the valve or passage through which the liquid is discharged;
the consequence is that the liquid is forced too suddenly up the syphon tube and
through the valve, and is thus liable to excessive frothing and loss of its gas; the
force also in most instances, unless great care is used, spills the liquid over the sides
of the vessel into which it is drawn, and should other liquid be in such vessel it is
likewise driven out, thus great care is requisite to open such syphons by degrees,
which is only done by persons well acquainted with the use of syphon bottles.
My Invention consists,—
Firstly. In avoiding and overcoming the objections mentioned in the beforegoing
paragraph by keeping the internal tube of the "syphon" of smaller diameter than
the valve and discharge orifice, also in contracting the lower end of the syphon
tube so that the hole or aperture is about one third or one fourth the size of the
I Prine G71

page_text: internal diameter of the syphon tube. Thus the gaseous or aerated liquid when
being drawn off from the syphon bottle travels from the bottle into the tube with
a corresponding diminished speed, and can be drawn off from a syphon bottle into a
glass or other receptacle gently without splashing or excessive frothing and loss
of gas.
I would have it understood that the larger, the upper, portion of the syphon tube
is made over the lower end or admission orifice thereof, the less force will be given
to the liquid when beng drawn off.
Secondly. My Invention consists in a novel way of fitting the syphon tube and
stopper into the syphon bottle. I form a screw thread in the inside of the bottle
mouth or neck (by means of a metal mandril or otherwise) to correspond with
an outside screw on the syphon head, which latter is provided with an elastic
packing to make joint between the syphon head and the top of the bottle mouth.
Inside the syphon head I form a female screw which receives a male screw or
coupling which carries the glass tube of the syphon, which glass tube may be
contracted at its lower end as herein before stated. The screw coupling which
connects the glass tube to the syphon head is also provided with an elastic washer
to form an air tight joint with the syphon head.

LÉON VALLET, of Liverpool, in the County of Lancaster. "IMPROVEMENTS IN
AND RELATING TO 'SYPHONS' FOR AERATED OR GASEOUS BEVERAGES AND
LIQUIDS."
This Invention relates to certain improvements on the well known high pressure
syphon bottle for containing aërated or gaseous beverages and liquids, and has for
its object the reduction or checking the force with which aërated or gaseous
beverages or liquids from ordinary syphon bottles are generally discharged, the force
of the discharge being arrested within the syphon bottle; further, a great saving by
the retention of the gas in the bottle is effected. The liquid drawn off also retains
its gaseous state for a longer period than is the case with liquids drawn from the
common syphon. I have given the syphon bottle constructed according to my
Invention the title of the syphon moderateur.
According to the usual construction of syphons for gaseous or aërated liquids no
particular attention is given to the fact that the syphon tube should be smaller in
internal diameter than the valve or passage through which the liquid is discharged;
the consequence is that the liquid is forced too suddenly up the syphon tube and
through the valve, and is thus liable to excessive frothing and loss of its gas; the
force also in most instances, unless great care is used, spills the liquid over the
sides of the vessel into which it is drawn, and should other liquid be in such vessel
it is likewise driven out, thus great care is requisite to open such syphons by
degrees, which is only done by persons well acquainted with the use of syphon
bottles.
My Invention consists,―
Firstly. In avoiding and overcoming the objections mentioned in the beforegoing
paragraph by keeping the internal tube of the "syphon" of smaller diameter than
the valve and discharge orifice, also in contracting the lower end of the syphon
tube so that the hole or aperture is about one third or one fourth the size of the
internal diameter of the syphon tube; thus the gaseous or aërated liquid when
being drawn off from the syphon bottle travels from the bottle into the tube
with a correspondingly diminished speed, and can be drawn off from a syphon
bottle into a glass or other receptacle gently without splashing or excessive frothing
and loss of gas.
Secondly. My Invention consists in a novel way of fitting the syphon tube and
stopper into the syphon bottle. I form a screw thread in the inside of the bottle
mouth or neck (by means of a metal mandril or otherwise) to correspond with an
outside screw on the syphon head, which latter is provided with an elastic packing
to make joint between the syphon head and the top of the bottle mouth. Inside
the syphon head I form a female screw which receives a male screw or coupling
which carries the glass tube of the syphon, which glass tube may be contracted at
its lower end as herein before stated. The screw coupling which connects the glass
tube to the syphon head is also provided with an elastic washer to form an air-
tight joint with the syphon head.
The beforegoing being the nature, object, and purposes of my Invention, I will
now proceed to illustrate how my Invention may be practically applied, and to
describe forms and arrangements of apparatus such as are suitable for carrying my
Invention into practice, and for that purpose I have attached a Sheet of Drawings
illustrative of two syphons constructed according to my Invention; the
Drawings are marked with letters and figures of reference corresponding with
those in the following explanation, like letters and figures being used to denote
the same or corresponding parts throughout the various views.

page_text: Figure 1 is a sectional elevation of a syphon constructed according to my
Invention.
Figure 2 is an outside view of Figure 1.
Figure 1 is a section through syphon tube at X.
Figure 3 is a sectional elevation of a modification of Figure 1.
Figure 4 is an outside view of Figure 3.
Upon reference it will be seen that A is the bottle, into the mouth or neck of
which is screwed the syphon head B fitted to the bottle with the elastic washer C;
D is the discharge spout; E, the spring; F, the valve opening lever; H, the valve;
J, the syphon tube coupling; K, the syphon tube.
Referring to Figure 1, my Invention consists, firstly, of making the internal
tube K of the syphon of smaller diameter than the discharge valve H, and the
passage R and the discharge spout D of the syphon, and in contracting the lower
end of the internal or syphon tube K, so that the hole or aperture S is about one
third or one fourth the size in area of the internal diameter of the syphon tube K.
By so constructing the internal tubes of syphons the gaseous or aerated liquid when
being drawn off from the syphon bottle travels from the bottle through the
aperture S into the tube K with a diminished speed, and can be drawn off from a
syphon bottle into a glass or other receptacle gently without splashing or excessive
frothing and loss of gas.
Upon further reference to Figure 1 my Invention consists, secondly, of a novel
way of fitting the syphon tube K and the syphon head B to the syphon bottle A.
It will be seen that I form a screw thread in the inside of the bottle mouth or
neck at T, which corresponds with a male screw on the syphon head B at V; C is
an elastic washer which makes joint between the syphon head B and the top of
the bottle A. Inside the syphon head B I form a female screw W, which receives
a male screw on a coupling J which carries the glass tube K of the syphon, which
glass tube may be contracted at S, as before described, or may be an ordinary tube.
The coupling J is provided with an elastic washer M to make joint with the
syphon head B.
Figure 3 of the Drawings represents my Invention of a tube K having a con-
tracted end S, and applied to an ordinary syphon bottle.
Having now described the nature of my Invention, and explained how the same
may be carried out into operation, what I claim as my Invention is,―
Firstly. Constructing the internal tubes of syphon bottles so that the area of the
tube is less than the area of the valve and discharge passage and spout of the
syphon, and contracting the lower end of the syphon tube K in manner such as
shown at S in the accompanying Drawings for the purposes hereinbefore described.
Secondly. Attaching the syphon tube K by means of a coupling, such as J, to the
syphon head B, substantially as herein described and shown in Figure 1 of the
accompanying Drawings.
Thirdly. The arrangement of parts forming a syphon bottle, substantially us
herein described and shown at Figure 1 of the accompanying Drawings.
In witness whereof, I, the said Léon Vallet, have hereunto set my hand and
seal, this Sixteenth day of September, in the year of our Lord One thousand
eight hundred and seventy nine.
LEON (L.S.) VALLET.
