Improvements in Heads or Stoppers for Syphons.
I, CARL BOLLÉ, of 57, Barton Arcade, Manchester, in the County of Lancaster,
Consulting Engineer, do hereby declare the nature of this invention, which has
been communicated to me by Rudolph Winnikes, of 214, Friederich Strasse,
Berlin, S.W., in Germany, Merchant, to be as follows:.
-
This invention consists in an improved arrangement or construction of a
stopper or head intended chiefly for use on larger syphons filled with beer and
free carbonic acid or similar fluids, so that after a valve in the syphon head has
been opened the beer or other liquid is forced out by the pressure of the carbonic
acid, permitting any desired quantity to be drawn.
The beer syphons provided with the improved syphon stopper are chiefly
intended to replace bottled beers and contain moderate quantities of beer. In
order to make their use practicable, it is necessary that the head or stopper
should be easily removable for cleaning and re-filling the syphon, and should
itself be convenient to clean in all its parts. The object of my invention is
to produce a stopper or head fulfilling these conditions.
In carrying my invention into effect, I form the neck of the syphon or beer
bottle with an internal thread, and the stopper with a corresponding external
thread. As the stopper is made of hard metal, and as in using such a stopper
the neck of a glass bottle would be easily burst if the stopper were screwed in as
strongly as required for making a tight joint at the upper edge of the bottle,
this risk is obviated by slipping an elastic sleeve, for instance, of india-rubber
over the threaded part of the stopper. This sleeve forms an elastic intermediate
layer which prevents a bursting of the bottle neck, and serves to form a packing
which can be readily renewed at any time. The sleeve also forms a self-acting
non-return valve where a separate passage through the stopper is provided for
the introduction of the carbonic acid, the passage being formed with a lateral
outlet under the sleeve in the projecting end of the stopper. The stopper can
thus be readily removed from the beer bottle and cleaned in its external parts.
In order to allow the internal parts of the syphon stopper to be easily cleaned,
it is formed with a central straight through bore, which in its lower part has
about the same diameter as the descending internal syphon pipe, which is
connected by an india rubber sleeve to the reduced bottom end of the stopper.
The upper part of the bore is enlarged and screwed internally and into it an
externally screwed valve spindle is inserted formed with a milled button at
the top, by means of which the valve can be screwed down. The valve spindle
is packed by means of a deep india-rubber ring slipped on to the same above
the thread and fitting into a further enlarged part of the central bore of the
stopper. The ring is preferably made of such depth, that when the valve is
open, it is already slightly compressed between a shoulder on the spindle and
another on the stopper, and is further compressed to close the valve. The
lateral outlet branch pipe starts from the central bore above the valve seating.
In consequence of these arrangements the valve spindle with the packing ring

through. bore of the stopper can be cleaned with equal facility. The rubber
packing ring can readily be slipped off the valve spindle and cleaned or renewed.
Improvements in Heads or Stoppers for Syphons.
I, CARL BOLLÉ, of 57, Barton Arcade, Manchester, in the County of Lancaster,
Consulting Engineer, do hereby declare the nature of this invention, which has
been communicated to me by Rudolph Winnikes, of 214, Friederich Strasse,
Berlin, S.W., in Germany, Merchant, and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
This invention consists in an improved arrangement or construction of a
stopper or head intended chiefly for use on large syphons which are filled with
beer or similar liquid and free carbonic acid so that after a valve in the syphon
head has been opened the beer or other liquid is forced out by the pressure of
the carbonic acid, permitting any desired quantity to be drawn.
The beer syphons provided with the improved syphon stopper are chiefly
intended to replace bottled beers and thus contain moderate quantities of beer
to be drawn of as required. In order to make their use practicable it is necessary
that the head or stopper should be easily removable for cleaning and re-filling
the syphon, and should itself be convenient to clean in all its parts. The object
of my invention is to produce a stopper or head fulfilling these conditions.
On the drawing appended hereunto Figure 1 shows a section of the syphon
neck and head or stopper, Figure 2 a view of the valve plug with the packing
ring in section.
In carrying my invention into effect, I form the neck of the syphon or beer
bottle B with an internal rounded screw thread, and the head A with a corre-
sponding external thread on the lower part a forming the stopper for the syphon
bottle. As the stopper is made of hard metal, for instance of brass, and as in
using such a stopper the neck of a glass bottle would be easily burst if a metal
stopper were screwed in as firmly as required for making a tight joint at the
upper edge of the bottle, this risk is obviated by slipping an elastic sleeve b
preferably of india-rubber over the threaded part of the stopper. This sleeve
forms an elastic intermediate layer which prevents a bursting of the bottle neck,
and serves to form a packing which can be readily renewed at any time. The
sleeve if made of india-rubber or impermeable at the part covering the passage
also forms a self-acting non-return valve where a separate passage d through
the stopper is provided for the introduction of the carbonic acid, the passage d
being formed with a lateral outlet under the sleeve in the projecting end of
the stopper. The stopper can thus not only be readily attached to and removed
from the beer bottle but also quickly and thoroughly cleaned in all its external
parts.
In order to allow the internal parts of the syphon stopper to be as easily
cleaned, it is formed with a central straight through bore, having in its lower
part E about the same diameter as the descending internal syphon pipe S which
is connected by an india-rubber sleeve c to the reduced bottom end a of the
stopper. The upper part F of the bore is enlarged and screwed internally and
into it an externally screwed valve plug or spindle G is inserted formed with a

page_text: milled button g at the top, by means of which the plug can be screwed up or
down. An india-rubber or other valve h is attached to the bottom of the plug G
and when pressed upon the seating f closes the outlet from the bottle B. The
valve plug or spindle G is packed by means of a deep india rubber ring i slipped
on to the same into a circular recess formed thereon above the thread, as shewn
on Figure 2, and fitting into a further enlargement of the central bore of the
stopper. The ring is preferably made of such depth, that when the valve is
open the ring is already slightly compressed between the upper shoulder on
the spindle and the shoulder on the stopper, and is further compressed to close
the valve. The lateral outlet branch pipe t starts from the central bore above
the valve seating.
In consequence of these arrangements the plug or valve spindle G with the
packing ring i can be easily screwed out of the stopper A and cleaned externally,
while the straight through bore of the stopper and the pipe S can be cleaned
with equal facility. The rubber packing ring i can be readily slipped off the
valve spindle and cleaned or renewed.
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 construction of a head or stopper for syphons of two separately detach-
able parts arranged substantially as herein before described and illustrated by
the drawings and for the purpose set forth.
2. In a head or stopper for syphons the use of an elastic sleeve surrounding
the lower part of the stopper formed with a rounded screw thread for screwing
herein before
into the corespondingly formed bottle neck, substantially as
described and illustrated by the drawing.
3. In a syphon head or stopper formed with a screw threaded part surrounded
by an elastic sleeve for attaching the head or stopper to the bottle, the arrange-
ment of a passage in the stopper for charging the liquid with carbonic acid,
issuing underneath the elastic sleeve in the protruding end of the stopper sub-
stantially as hereinbefore described and illustrated by the drawings.
