PROVISIONAL SPECIFICATION.
Improvements in Draught Tubes of Syphon Bottles.
I ROBERT GARRARD of Maybury Heath, Woking in the County of Surrey,
Wine Merchant do hereby declare the nature of this invention to be as follows:-
Draught tubes ordinarily employed for syphon bottles which are charged with
aërated liquids, form a direct channel from the outlet valve to the bottom of the
bottle. Thus when the valve is driven from its seating the discharge of liquid
takes place almost instantaneously and with such force usually that much of the
liquid escapes from the glass held to receive it. This inconvenience is the greater
in the case of drinks which from the nature of their ingredients are liable to froth
more than ordinary aërated waters, the loss too being of serious moment in the case
of expensive wines filled into syphon bottles.
The object of my invention is to obstruct the passage of the liquid in its course
from the bottom of the syphon bottle to the point at which the closing valve is
situated. For this purpose I make the draught tube in the form of a spiral coil
one end of which dips close to the bottom of the bottle while the other end is
either formed in cup shape or is fitted with a metallic or other cup to form the
flanged enlargement required for surrounding the valve and for fixing the tube
within the syphon top in the usual and well known manner.
By this means the length of the channel from the valve to the bottom of the
syphon bottle is greatly increased and departs from the usual direct course achieving
the required result of preventing a too rapid discharge no matter how suddenly the
valve may be opened.
The object of my invention may be attained in other ways, for instance instead
of coiling the tube spirally I may make contractions in the tube arranged spirally
throughout its length or at some point in the tube I may place a plug in a recess in
such a manner that a free passage may be allowed to the liquid entering the syphon
bottle by way of the tube, to facilitate the filling operation; while the plug obstructs
the passage of the liquid in the other direction when passing outwardly from the
syphon bottle.

COMPLETE SPECIFICATION.
Improvements in Draught Tubes of Syphon Bottles.
I ROBERT GARRARD of Maybury Heath, Woking in the County of Surrey,
Wine Merchant, 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:-
Draught tubes ordinarily employed for syphon bottles which are charged with
aërated liquids, form a direct channel from the outlet valve to the bottom of the
bottle. Thus when the valve is driven from its seating the discharge of liquid
takes place almost instantaneously and with such force usually that much of the
liquid escapes from the glass held to receive it. This inconvenience is the greater
in the case of drinks which from the nature of their ingredients are liable to froth
more than ordinary aërated waters the loss, too, being of serious moment in the case
of expensive wines filled into syphon bottles.
The object of my invention is to obstruct the passage of the liquid in its course

page_text: from the bottom of the syphon bottle to the point at which the closing valve is
situated. For this purpose I make the draught tube as shown in the accompanying
drawing in which
Figure 1 shows my improved draught tube applied to a bottle of suitable shape
for champagne wines, and
Figure 2 is a sectional elevation of the tube removed from the bottle.
The draught tube A is made in the form of a spiral coil one end of which dips
close to the bottom of the bottle B while the other end is either formed in cup
shape as shown at C, or is fitted with a metallic or other cup to form the flanged
enlargement required for surrounding the valve and for fixing the tube A within
the syphon head E in the usual and well known manner.
By this means the length of the channel from the valve to the bottom of the
syphon bottle is greatly increased and departs from the usual direct course achieving
the required result of preventing a too rapid discharge no matter how suddenly the
valve may be opened.
The object of my invention may be attained in other ways; for instance instead
of coiling the tube spirally I may make contractions in the tube arranged spirally
throughout its length or I may give to the tube any suitable form which will
distort it from the direct course from the bottom of the bottle to the valve orifice
of the syphon. Any such arrangement is a mere modification of my invention
as hereinbefore described but I make no claim to any arrangement by which the
passage of the liquid shall be more restricted when flowing in one direction than
when flowing in the other such as that contemplated by the reference in my
Provisional Specification to an obstructing plug to be placed in the course of
the channel formed by the draught tube.
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 :-
A coiled or twisted draught tube for syphon bottles substantially as and for
the purposes set forth.
