PROVISIONAL SPECIFICATION.
Improvements in or connected with Seltzogenes and Syphons for
Aerated Waters.
Í, BLANCHE JULIA NICOLE, of 85, St. John Street Road, London, E.C., do.
hereby declare the nature of this invention to be follows:-
My invention relates to improvements in or connected with the heads of seltzo-
genes or similar articles and has for its object the dispensing with the collar
usually employed in attaching the head of the reservoir and an improved form
of valve.
To carry my invention into effect I preferably form the head which may be of
metal or other suitable substance or material with an internal screw or bayonet
joint but sometimes however I construct the head with a projecting lug at its
base. On the neck of the reservoir I mould form in or upon or adapt suitable
parts of metal or other substance which may be in sections to correspond and
engage with those in the head. When using that form where a lug is employed
I preferably use a suitable fastening device in the shape of a catch bolt or thumb-
screw I employ a packing of rubber asbestos or other material to form the joint
between the top of the reservoir & the head.
In the form of valve usually adopted the seating is placed so that the water
comes in contact therewith. To obviate this I use a seating of rubber asbestos or
other suitable material of a larger diameter so that the top of the glass tube which
is at this part larger than the other portion thereof shall rest against it.

COMPLETE SPECIFICATION.
Improvements in or connected with Seltzogenes and Syphons for
Aerated Waters.
I, BLANCHE JULIA NICOLE, of 85, St. John Street Road, London, (Married), 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 present invention has reference to mineral water vessels, such as seltzogenes,
and is directed to the improvement and simplification of the construction of the
head thereof, and also of the valve.
In the accompanying drawing, I have shewn the head of a seltzogene embodying
my improvements, and a portion of the reservoir to which it is attached.

page_text: A is the head proper, comprising the usual glass-lined spout a, and enclosing
within its central glass-lined chamber the valve rod B, provided with the ordinary
spring and lever bl.
The lower part of the head is provided with means for attaching it to the reser-
voir C, that is to say, the neck of the latter is furnished with a metal ringe, either
applied in sections, or cast in position upon the glass. This ring is so set that the
mouth of the reservoir extends somewhat beyond it in an upward direction. The
ring c is provided with an external thread, as shewn in the drawing, or, if pre-
ferred, with engaging lugs, by means of which the head (which has an internal
thread, as shewn), or the counterpart of the engaging device, may be screwed or
otherwise attached to the ring c. Within the head A is a washer d of rubber or
other suitable material, against which the mouth of the reservoir strongly bears,
when the head is screwed, on, and makes a tight joint.
E is the pendent glass delivery tube, which, according to my invention, is made
trumpet-mouthed, to enclose the valve e, attached to the extremity of the rod B.
The tube E beds against the washer e¹, and is held in place by means of the nut e²,
as shewn in the drawing.
The washer e' is also employed as a seating for the valve e, which is preferably
non-metallic, and is of cap form, as shewn. This valve encloses the end of the
tube f, extending from the syphon head, instead of bearing against it, as is usual.
With this arrangement, a better and more durable seating for the valve is
obtained.
The material of the seating will preferably be asbestos or vulcanite, but it may
also be of other materials.
According to this method of construction, the mineral water is entirely kept from
contact with the metal of the head, and, moreover, the usual collar employed for
attaching the head to the reservoir is dispensed with, thereby facilitating greatly
the fixing of the same.
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;-
1. The herein before described improvements in seltzogenes and the like, whereby
the attachment of the heads to the reservoirs is facilitated, and the contact of the
mineral water with the metal is entirely prevented, substantially as set forth.
2. The arrangement of valve and valve seat substantially as described with
reference to the accompanying drawing.
