improvement in Syphon Bottles.
We JAMES KEMP WELCH of Parkstone, Weybridge, in the County of Surrey,
Gentleman, and GEORGE BROWNEN, Fellow of the Chemical Society, Althorp Road,
Upper Tooting, in the County of Surrey, 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 :-
According to the present method of bottling aerated liquids in syphon bottles
hereinafter called Syphons the liquid is generally forced into the Syphon through
the delivery spouts which is an objectionable process. Syphons as at present con-
structed cannot be cleansed thoroughly without taking off the metal top or head and
the liquids contained in them are often contaminated by contact with the metal
valve and spout when such metal valve and spout are composed as they often are of
alloys containing lead or copper or both the soluble salts of which metals are
injurious and in repeated doses poisonous. The objects therefore of our present
invention are to construct Syphons in such a manner as to facilitate the filling and
cleansing of the same and also to prevent the contained liquid from coming in contact
with metal of any kind.
According to this Invention we fill the syphon by means of a special filling orifice
which may be at the bottom side or shoulder of the syphon such filling orifice is
provided with a neck and is closed with any suitable stopper such as a glass ball or
screw or a cork wired in the ordinary manner.
We also form the valve or other regulator for controlling the flow of the liquid
from the Syphon either wholly or partly of glass or other innocuous material in the
latter case the glass or other material must be so disposed that if any metal is used
in the construction of the regulator the contained liquid will not come in contact with
such metal.
And in order that our Invention may be the better understood we will proceed to
explain the same with reference to the accompanying sheet of drawings in which
Fig. 1 represents a longitudinal section of a Syphon constructed according to our
invention and Figs. 2 and 3 represent sections of regulators suitable for closing the
outlet orifice of the same also constructed according to this invention.

in this case a cork secured by wire in the ordinary way. To prevent damage to the
delivery pipe while cleansing or filling the Syphon we in some cases carry the same
down the side of the bottle as shewn in Fig. 1. The filling orifice may be placed at
the bottom as shewn in Fig. 1 at the shoulder as shewn in Fig. 2 or at the side of
the Syphon as shown in dotted lines Fig. 1. The Cocks or taps shewn at Figs. 1 and 2
may be made of glass, wood vulcanite earthenware porcelain or any other innocuous
material or a combination of glass and any of these materials may be used such as
metal cocks lined with glass or porcelain. The neck of the Syphon has the delivery
tube blown or fused into it or otherwise affixed in it such neck being externally
screwed, the cock or tap is also externally screwed and the joint made by means of
the socket and washer e the neck of the bottle and the cock may be formed one
with an external and the other with an internal thread so as to dispense with the
socket but we find that the form of joint shewn in the Drawings is the most satis-
factory when the cock is made of glass or other vitreous material. In Syphons
constructed as above the contained liquid comes in contact with nothing but glass
or equally harmless material. The cock or tap shown in figure I may be formed
integral with the Syphon bottle instead of being separate therefrom. Figure 3
shows a modification of the ordinary Syphon constructed so as to attain the objects of
our invention. The bibe is a part of the Syphon bottle a b is delivery pipe as blown
into the bottle a or manufactured and carried down straight as in Figure 2 flever
g spring to close the valve which may be either of glass or vulcanite or partly of
one and partly of the other i is valve stem of same material as valve hk is jointing
washing head or cap.
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 1
claim is :-
Claims I. Constructing Syphon bottles for containing liquids under pressure
with filling orifices at the bottom side or shoulder thereof substantially as
described.
II. The construction hereinbefore described of Syphon Bottles so that all the parts
in contact with the contained liquid are of glass or other equally harmless material
substantially as set forth.
III. The improved Syphon Bottles for containing liquids under pressure substan-
tially as described and set forth.
