FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, at
Frankfort on the Main, in the Empire of Germany. "IMPROVEMENTS IN SELF
CLOSING STOPPERS OR SIPHONS FOR BOTTLES CONTAINING AERATED LIQUIDS."
[A communication from Hendrik Beins and Jan Frederik Beins, both of Groningen,
in the Kingdom of Holland.]
This Invention relates to improvements in apparatus to be applied to bottles for
containing mineral-water and other gaseous liquids, by means of which apparatus
the liquid or any portion thereof may be caused to flow out when required.
Bottles provided with apparatus of this nature are ordinarily termed syphon-
bottles. The said Invention consists partly in making and arranging the parts in
such a manner that the liquid comes in contact only with hard india-rubber, or
glass, or other material which is not affected by the frequent contact of liquid, nor
influences the latter by its contact.
The said Invention further consists in arranging, independently of the outflow
tube, a valve which opens downward and through which the air escapes when the
siphon bottle is filled, or through which the carbonic acid is introduced for aerating
the water contained in the siphon bottle.
In carrying the said Invention into practice I place in the neck of the bottle the
lower part of a hard india-rubber block or body, which is separated from the bottle
by an india-rubber ring. In this block or body there is a hard india-rubber rod
arranged to move vertically, and provided at its lower end with an outlet valve
furnished with a washer or ring of soft india-rubber. By depressing the said rod
the valve at its lower end is caused to open, and the liquid flows out. The said
rod is at its upper end provided with a metal knob by which the rod is depressed.
The valve at the lower end of the rod is normally pressed against its seat by the
action of a spiral spring; a soft india-rubber washer prevents the liquid from coming
into contact with certain metallic parts of the apparatus, namely, a guide, the
aforesaid spiral spring, and the knob. The outflow tube is also made of hard
india-rubber or glass.

page_text: Over the lower end of the aforesaid india-rubber body or block a sleeve of hard
india-rubber is screwed, and in this sleeve a glass tube is cemented or otherwise
firmly secured. The bottle neck is provided with a metal ring, which consists of
two parts for adjustment and over which a cap is screwed. The latter keeps the
india-rubber body pressed firmly to the neck of the bottle.
In the india-rubber body is provided a small valve which by means of a spiral
spring is always pressed against its seat. When the valve opens the inner space of
the bottle is brought into communication with the outer air by means of a channel,
so that the carbonic acid may enter into the bottle; or, if desired, air may be
allowed to escape from the bottle when the latter is filled with water or other
liquid.
