Improvements in Syphons for Aerated Waters.
1 HENRY JAMES NICOLE of 210 Goswell Road in the County of Middlesex, Watch-
maker, do hereby declare the nature of this invention to be as follows:-
This invention relates to that class of vessels for aerated waters known as syphons,
which are provided at their upper ends with taps and valves through which the water
is forced by the pressure within the vessel on the opening of the valve by the
depression of a lever.
Hitherto, the taps employed in such syphons have been of metal, which is by some
found objectionable, and have also to be provided with a spring to keep the valve
against its seating.
According to my invention, am enabled to construct the tap entirely of the same
material as the vessel, viz., glass, and I dispense with the spring. The valve seatings
only are of another material, viz. india rubber, which is not objectionable.
In carrying out my invention, I construct the tap of glass in the form of a bell,
having the syphon tube secured in the mouth thereof, and having a spout in its side.
This bell is screwed into the neck of the vessel, and the syphon tube extends to near
the bottom thereof in the usual way. In the summit of the bell is a circular hole for
receiving a spindle, the lower end of which is provided with a ball or cone. This
ball or cone beds against an india rubber seating near the mouth of the bell, and forms
therewith a ball or cone valve, which is held closed by the pressure of the liquid
within the syphon. The upper end of the valve spindle projects above the bell
summit, and is furnished with a button, by means of which it may be depressed to
open the valve. Should the power of the thumb direct upon the button be deemed
insufficient to overcome the pressure of the liquid in the bottle, it may be desirable
to employ a lever. This may be readily done by providing a metallic ring around
the glass bell, and hinging thereto a lever which passes over the summit of the vaive
spindle. As the metal does not come in contact with the liquid, its employment for the
lever cannot be objected to.

Improvements in Syphons for Aerated Waters.
I HENRY JAMES NICOLE of 210 Goswell Road in the County of Middlesex, Watch-
maker, 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 relates to that class of vessels for aerated waters known as syphons,
which are provided at their upper ends with taps and valves through which the water
is forced by the pressure within the vessel on the opening of the valve by the
depression of a lever.
Hitherto the taps employed in such syphons have been of metal, which is by some
found objectionable, and have also to be provided with a spring to hold the valve
against the pressure of the liquid.
According to my invention, I am enabled to construct the tap entirely of the same
material as the vessel, viz., glass, and to dispense entirely or partially with the spring,
and make the valve self closing. The valve seatings only are of another material, say,
india rubber, which is not objectionable.

page_text: My invention is illustrated in the accompanying drawing, whereof Fig. 1 is a
sectional elevation, and Fig. 2 a similar view, showing a modified form of valve.
Fig. 3 shows another mode of connecting the tap with the bottle.
A is a vessel or receptacle to contain the aerated liquid. B is the syphon tube
introduced into the mouth of the vessel A, and extending nearly to the bottom thereof.
C is a block of glass or similar material, bell mouthed to embrace the neck of the
vessel A. c is a vertical passage through the block C, and c' is a diagonal passage
communicating with the passage c, and forming a spout.
The tap for the syphon is formed at the lower end of the passage c within the
block C, by a ball e or its equivalent upon the end of spindle E, passing through the
vertical passage. The ball e beds against a seating of rubber fitted into the glass,
and is held thereon by the pressure of the aerated liquid within the vessel.
The spindle E extends upward beyond the block C, and is provided with a pressure
button (or with a pressure lever, as in Fig. 2, where additional force is desired). The
spindle E is of less diameter than the passage c, so that when the ball e is forced
from its seating and the valve opened by depressing the spindle, the liquid is able to
riso up the said passage until stopped by the washer or stopping f, which surrounds
the spindle E at a point just above the spout e', down which spout the liquid therefore
escapes. The bell mouth of the glass block () is threaded internally to screw onto
the externally threaded neck of the receptacle A, as illustrated.
In the modification shown at Fig. 2, the depressing lever is fulcrummed in the
side of the passage c, and passes transversely through the head of the spindle E', and
through the opposite side of the passage, where there is a slot to permit of up and
down movement sufficient for the opening and closing of the valve.
The pressure of the aerated liquid will generally be sufficient to keep the valve
closed, but a light compression spring surrounding the head of the spindle (outside
the bottle) may be used to assist the pressure of the liquid, if desired, without
interfering with the general construction of the tap.
In this case, the valve is formed by a loose washer of india rubber surrounding the
the spinde and resting on the ball e.
In Fig. 3, the block of glass C, forming the head of the syphon, instead of having
a bell mouth, is provided with a neck threaded externally for screwing into the
internal threaded neck of the vessel A. To make the joint perfectly air tight, a
washer of india rubber is placed round the neck, so as to form an elastic packing
between the head C and vessel A.
It will thus be evident, that the employment of metal for syphon taps in contact
with aerated water, may be entirely avoided.
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 :-
Constructing syphon taps in the manner described and shown, whereby I am
enabled to employ non-metallic materials in contact with the liquid, and to dispense
with the strong spring usually employed for holding the valve against the pressure of
the liquid in the vessel.
