Improvements in Syphons for Aërated Liquids.
We GEORGES FERRAND and GUSTAVE GOETTL, Engineers, of 37, rue Philippe-le-
Bon, Bruxelles, in the kingdom of Belgium, do hereby declare the nature of our
invention to be as follows:-
-
Our invention has for its object to increase the solidity and tightness of syphons,
and to avoid as much as possible the contact of the liquid with metal.
The principal features of novelty are a cap made of glass, porcelain or similar
material and provided with a lateral outlet for the liquid; and a capsule of india-
rubber or other suitable material, over which the cap is placed and which in its turn
fits over a conical bottle neck as well as, over a conical head terminating the
elevating tube or central tube of the bottle, a tight joint being formed between the
said head and neck by means of a washer or packing ring placed between the two
parts.
If the cap is forced down by means of a screw or other appliance, a packing disc of
india-rubber, cork or other suitable material situated in the interior of the cap and
facing the conical tube-head, closes tightly the axial opening of the said tube-head
forming the prolongation of the lifting tube, so as to prevent all escape of fluid.
Each of the two superposed cones (namely the bottle neck and the head of the
syphon tube) has an annular recess, to receive the extremity of a clamp or clamps of
hard rubber serving to unite the two superposed cones, so as to form one rigid cone,
over which fits the conical capsule made of elastic material as mentioned above.
The interior of the cap fitting over the capsule is made conical with two short
cylindrical ends, the lower extremity fitting over the neck of the bottle.
The screw serving to tighten the cap is preferably secured to a hoop attached with
its ends to the neck of the bottle in any convenient manner. For this purpose the
lower part of the bottle neck may be encircled with a pair of semicylindrical rings,
resting against a collar of the neck and provided with an external screw thread.
Over the said rings is screwed a circular ring having a pair of radial studs for
attaching the hoop.

COMPLETE SPECIFICATION.
Improvements in Syphons for Aörated Liquids.
We, GEORGES FERRAND, and GUSTAVE GOETTL, Manufacturers, of 37 rue Philippe-
le-Bon, Brussels, Belgium, 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:-
This invention relates to syphon heads or appliances for delivering aërated water
from bottles containing the same, the object being to construct a syphon head which
secures durability and absence of leakage, even with high pressure, and also to prevent
as far as possible, the contact of the liquid with metal.
As illustrated by the accompanying drawings, Figs. 1 to 9, the improved syphon
head chiefly comprises a cap B, provided with a lateral discharge pipe B', and made
of glass, porcelain, stone ware, or other suitable material. A capsule C, of india-
rubber over which the cap is placed, and which in its turn fits over the conical bottle
neck a and the conical head d of the elevating tube D, so as to hold the two parts
together and form a tight joint. E is a washer or packing ring of indiarubber placed
between a and d.

page_text: If the cap B is forced down by means of a screw L, or other appliance, a packing
disc F of indiarubber, cork or other material situated in the interior of the cap B and
adapted to rest with its face on the conical tube head, closes tightly the axial opening c
of the said head forming the prolongation of the lifting tube D, so as to prevent an
escape of liquid or of gas.
For fitting the different parts together, the indiarubber disc F (Figs. 1 and 5) is
placed upon the conical head a of the bottle A and the tube D, (Fig. 4) introduced
through the bore e and the neck of the bottle, so that the head d will rest on the
disc E, (Fig. 5.) The conical extension a and the head d, are made of such a shape
that d forms a continuation of the truncated cone a. The conical surface of both
parts is provided with parallel grooves. The capsule C, (Fig. 3) is now stripped over
the cones a and d, and holds them together to a certain extent. The interior of the
cap B, which is now mounted on the indiarubber capsule comprises three parts;
namely a cylindrical part 64, (Fig. 2) adapted to slide up and down on the bottle
neck, the conical part 6, which fits on the sides of the capsule C, and a short,
cylindrical part b¹, which receives the packing ring F, serving to close the outlet of
the capsule. The cap B is pressed on the capsule by hand, thereby compressing
the enclosed parts, namely the capsule C, extension a, disc E, and tube head d and
producing a tight fit. The part 6 of the cap B is accurately guided over the part a¹
of the bottle neck.
If now the hoop K, (Fig. 7) is placed in a vertical position, and the point of the
screw spindle L pressed into the small conical recess of the cap, (Fig. 2) the bottle
will be at once closed with certainty, inasmuch as the packing disc È shuts the outlet
of the indiarubber capsule C. The bottle can be opened again with facility, by
turning the spindle L slightly backward.
The screw thread of the spindle L is interrupted by an annular groove M¹,
(Fig. 9) placed in such a position, that when the point of the spindle slightly
touches the recess of the cap B, the groove M¹ will be situated immediately
underneath the bridge of the hoop K.
Into this groove is then placed the metal ring M, (Fig. 9) and pressed fast by a
pair of pincors. The object of this arrangement is to prevent the spindle L from
being screwed up too high.
The hoop K may be secured to the bottle in any known manner; for instance, as
shown by Figs. 7 and 8, by means of two semicircular bushes H1, H2, (Fig. 8)
provided with screw threads and situated behind the flange A¹, the said bushes being
held to the neck of the bottle A by a metal ring G. The latter has two studs 9, g, to
which the hook K is secured.
The principal advantages of this apparatus are, besides cheapness of manufacture
and the avoidance of contact between liquid and metal, that the different parts can be
rapidly put together and exchanged, and that the cap, if made of transparent material,
allows one to detect any impurity in the interior.
As shown by Figs. 10, 11 and 12, the conical head B of the ascension pipe C may
form a separate piece extended downward below the indiarubber capsule. The lower
part of the capsule is made of metal and extends below the cap H so as to form one
piece with the screw nut E which holds the semicircular bushes already enclosing the
bottle neck A. The conical head B has at its lower_end a flange, between which and
the neck of the bottle is placed a packing ring D. F is a packing ring placed between
the lower edge of the cap H and the screw nut E. n is a screw spindle which enters
a metallic socket piece m fitted into a recess of the cap H. This spindle is provided
with a knob K and with a stop ring situated underneath the bridge of the yoke J.
x, x, are the trunnions or pivots for the yoke J, and y, y, are a pair of set screws for
fixing the yoke in its vertical position.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
-
1. An aërated water or syphon bottle in which the ascension pipe D and the bottle

page_text: neck are enclosed by a capsule made wholly or partly of indiarubber, which in its
turn is enclosed by a cap provided with the discharge pipe, the whole being so
arranged that the outlet may be opened or closed by simply raising or depressing the
said cap; substantially as described.
2. The combination of ascension pipe D and bottle neck a, with an indiarubber
capsule C, enclosing the same, and a cap B containing the ontlet pipe, the whole
being constructed and adapted to operate substantially as described with reference to
Figs. 1 to 9.
