PROVISIONAL SPECIFICATION.
Improvements in Syphons and Seltzogenes for Aerated Waters.
I HENRY JAMES NICOLE, of 210 Goswell Road in the County of Middlesex,
Watchmaker, do hereby declare the nature of this invention to be as follows:-
The object of the present invention is to improve the construction of the taps used
in syphons for aerated waters.
In carrying out my invention, I employ the ordinary tap casing, screwed or other-
wise secured to the mouth of the vessel containing the aerated water. The mouth of
the vessel, which is usually of glass, is cut off from the tap body by a washer of rubber,
or other non-metallic substance, and through the washer passes the glass syphon tube,
the lower end which extends to near the bottom of the vessel. The upper en of the
tube is firmly seated against a seating situated in the tap casing just above the spout,
which occupies the usual position. The glass syphon tube has a hole in the side
thereof, just opposite the spout above mentioned.
In the upper part of the tap casing, and passing downwards through the seating,
against which the syphon tube is pressed, is a spring plunger, having on its lower end
a plug capable of sliding in the upper part of the syphon tube. The normal position
of this plug, held down by the spring, is exactly opposite the hole in the syphon
tube, so as to close the aperture, and prevent the aerated water from escaping into the
spout.
To open the tap, when it is required to draw some water for use, a lever is arranged
so as to raise the spring plunger, and thereby open the aperture between the syphon
tube and the spout. The liquid within the vessel will then, by its own pressure, rise
and escape by the spout in the usual manner. The spout of the tap is preferably lined
with glass or similar non-metallic substance, so as to avoid the prejudicial effect of
metallic contact on the aerated water as much as possible.
The spring of the spring plunger is so regulated as to give way and allow the tap
to open slightly, should the pressure of the gas within the liquid be too great, and
therefore liable to break the vessel. An efficient safety valve is thus afforded, which
is a point of importance in seltzogenes, in which the consumer commonly aerates the
water at home.
As a modification of the above described arrangement, I may, instead of providing
the spring plunger with a plug sliding in the syphon tube, fix the lower end of the
said plunger to the tube, and allow the latter to have a slight longitudinal sliding
movement, so as to ease it from its seat, and allow the water to escape from the top,
when liquid is required to be drawn. In this case, there is no hole in the side of the
syphon tube, and the spring acts upwards instead of downwards, the lever being a
depressing, instead of a lifting lever, as in the first case.

Improvements in Syphons and Seltzogenes for Aerated Waters.
1 HENRY JAMES NICOLE of 210 Goswell Road, in the County of Middlesex,
Watchinaker, do hereby declare the nature of this invention and in what manner the
[Price 8.1

following statement :-
This invention relates to the improvement of the taps of sypbons and seltzogenes.
for aerated waters, with the view of reducing, to the utmost, the metallic surface with
which the aerated water comes into contact, and thereby avoid the prejudicial effect
which the metal is found to produce on the liquid.
According to my invention, I line the lower part of the body of the tap with a
piece of glass tube, which, with the aid of india rubber washers, forms a non-metallic
chamber, from whence the aerated water admitted, under pressure, through the syphon
tube, can escape through a side hole into the spout, which is also lined with.
glass.
In the vertical section, Figure 1 of the accompanying drawings, the upper part of
the syphon tube a forms the lining of the lower portion of the tap body A.
The body of the tap A is of the usual metal employed for the purpose, and is pro-
vided below with a bell mouth internally threaded for screwing onto the collar b,
wherewith the vessel B containing the aerated liquid is furnished.
is a rubber washer clamped between the vessel B and the tap to form a tight
joint. Through a central hole in this washer, passes the syphon tube a, which
extends upwards into the tap body, somewhat above the glass lined spout. The syphon
tube is pierced horizontally exactly in line with the glass lined spout, and this
aperture is normally closed by the piston plug c, which accurately fits and slides
within the tube u.
This plug e is carried on the end of piston rod C, which extends upwards within the
tap easing D is a lever pivotted in the tap casing, and having its nose inserted in a
vertical slot c¹ in an enlarged cylindrical portion of the piston rod, for the purpose
of lifting the plug c, and opening the syphon. d is a compression spring for holding
the plug c down against the pressure of the aerated water. In syphons of this con-
struction, it will be seen that the aerated water is effectually preserved from contact
with the metal casing.
The sectional view Fig. 2 illustrates a slight modification. In this case, the lower
portion of the body of the tap A is lined by a short piece of tube a", pierced at the
side opposite the glass lined spout, and closed at top by the washer e, and at bottom
by the washer b'. The syphon tube a is of smaller diameter than the tube a°, and
arranged to slide through the washer 6, operated by the piston rod C, to which it is
attached. The upper end of the syphon tube a seats itself against the washer e, where
it is retained by the spring d.
The lever D, in this case, is arranged to depress the piston rod, instead of lifting it,
as in the first case.
In Fig. 3, the piston rod passing through the washer e, carries on its end a plug c
for closing the mouth of the syphon tube a. The other parts are the same as those
described with reference to Figs. 1 and 2. The form of valve shewn at Fig. 3 is
particularly applicable for seltzogenes in which aerated water may be prepared, as the
the spring may be so adjusted that the plug e will act as safety valve, should the
pressure within the vessel prove dangerously great.
Fig. 3 shows detached a slightly modified form of plug, which instead of consisting
of a ball as shown in Fig. 3, may be a rubber disc held between flanges of glass on
the glass spindle C).
In Figs. 4 and 5, the tube lining a* of the lower portion of the tap body, is about
the same diameter as the syphon tube a, but is not a part of it. The latter is flared
out at the top, to give space for the valve plug c, which seats against the lower end of
the tube a*.
Fig. 5 illustrates the application of the tap to a seltzogene, the bell mouth, at the
lower part, being screwed onto the metallic fitting of the seltzogene. is a short
piece of glass tube within the vessel, for preventing contact of the liquid with the
metallic fitting.

page_text: A safety valve, preferably in the metallic fitting, is usually provided in seltzogenes,
but it not shown in the present drawing.
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
The construction and arrangement of syphon tap substantially as shown and
described with reference to the accompanying drawings.
