page_text: I, MATHIAS VON NÁDASSY, of No. 10 Museum Ring, in the City of Budapesth and
Austro-Hungarian Empire, Gentleman, do hereby declare the nature of my said
invention and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement
My invention relates to a novel construction of a non metallic siphon and consists
substantially in manufacturing siphons, for drawing off aerated and other liquids,
from pressed glass, porcelain, majolica or other appropriate non metallic material.
Figure 1 is a vertical section of my improved siphon applied to a bottle for aerated
or other liquids.
Figures 1 to Figures 7 represent details of the construction.
The siphon or siphon head A is made of glass, porcelain or other appropriate non
metallic inaterial and is of the usual form, the valve B and valve stem being made of
one piece.
The valve seat and casing C is also made of one piece, the lever D can be inserted
in the finished siphon head and the parts attached to the flange of the neck of the
bottle in a novel manner.
As aforementioned the head A is made of one piece of glass, porcelain, majolica or
other appropriate non metallic material and is provided with a central vertical canal
into which the valve casing C, which carries the valve B, is inserted. The upper end
of the valve stem is provided with a tip or enlarged upper part which is in contact
with the lever, and made of india rubber, bone or other appropriate non metallic
material.
A packing ring a of india rubber is arranged above the valve whilst that part of the
valve stem iummediately above the valve casing is provided with a bone or india
rubber ring between which, and the upper edge of the valve casing, I arrange two
india rubber packing rings band between the above named bone or india rubber ring
on the valve stem and the head thereof a helical spring c.
An oblong opening provided in the upper part of the siphon for the lever D) and
the shel! or casing d, which is inserted in said opening and carries the lever D. The
valve seat lies snugly against the flange of the valve casing on the one hand, and

page_text: on the other hand against an india rubber ring placed on the upper surface of the
bottle flange. The aforedescribed valve and valve casing can he employed to great
advantage not only for non metallic but also for metallic siphons as in consequence of
their great simplicity the same can he readily interchanged as they only need to be
inserted in the siphon head. This is of very great importance to those trading in
siphons as it is only necessary to fit the parts B and C together and then place them
in the bottle.
The lower surface of the bottle flange is provided with three lateral cavities or
recesses g, h, whilst the lower part of the siphon is provided with three corresponding
teeth or lugs.
In placing the siphon on the bottle the teeth or lugs of the former are fitted into
the cavities or recesses g of the bottle flange and the siphon firmly pressed onto the
bottle which is allowed by the ring f, whereupon the siphon is turned round until the
upper edge of the teeth or lugs on the siphon catch into the recesses h. This method
of attachment is much more convenient than the ordinary system of screwing on the
siphon.

Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, what I claim is :—
In siphons for drawing off aerated and other liquids, the use of a valve B made of
one piece with the valve stem, the tip being made from a separate piece, and a valve
casing of one piece; the method of fitting the lever D from the exterior into the
finished siphon by means of the casing d and attaching the siphon to the bottle in
such manner that the inner wall of the siphon is provided with three or more or less
teeth or lugs which are inserted in corresponding cavities or recesses g and the siphon
then turned until the said teeth or lugs catch into the recesses in the lower surface
of the flange of the neck of the bottle, substantially as and for the purpose set forth in
the foregoing specification, and illustrated in the accompanying drawings.
Dated this 29th day of April 1889.
