We, JOHANNES LUDOVICUS WESTRUS and REINFERUS SCHOLS, both of 28, Kromme
Waal, Amsterdam, in the Kingdom of Holland, Manufacturers of aerated beverages,
do hereby declare the nature of this invention, and in what manner the same is to
be performed, to he particularly described and ascertained in and by the following
statement:
This invention relates to an improved construction of syphon bottles such as bo
obviate liability of the contents being injured by contact with metal, and to machinery
for charging a series of bottles containing liquid, with gas under pressure, which
machinery can with devices hereinafter described be used for charging other bottles
such as those closed by ball stoppers.
In the accompanying two sheets of drawings,
Fig. 1 is a vertical section and Fig. 2 a side elevation of a syphon bottle according
to this invention.
Fig. 3 is a side elevation partly in section of machinery or apparatus for charging
bottles containing liquids, with gas under pressure.
Fig. is an elevation at right angles to Fig. 3.
Fig. 5 is a sectional detail view hereinafter referred to.
Referring to Figs. 1 and 2, A is the body of the bottle which may be of glass and
of any suitable form. B is a metal tube (formed in two parts fastened together on the
bottle) provided with an external screw thread on which is screwed a metal cap C.
The cap is provided at one side with a screw threaded tubular projection on to
which is screwed the tube D which serves to secure the spout E in place as shown.
F is a hollow plug located within the cap C. E is a washer of suitable material such
as india-rubber, interposed between the inner end of the spout E and the hollow plug F
to ensure a water or fluid tight joint. G is a pipe arranged to work through the
hollow plug F the outlet at its lower end is at one side, and is normally closed by an
india-rubber ring G, which serves as a valve to admit of gas under pressure passing
from the pipe G to the interior of the bottle. The spout E, plug F, and pipe Gare
formed of ebonite or some other material such that the fluid which passes it shall not
be injured, as would happen if these parts were made of metal which would be liable

rounding the pipe G and faced with suitable material such as india-rubber which
normally rests against the surface of the lower end of the plug as a seat to prevent
liquid under pressure within the bottle escaping around the pipe & through the hole
in plug F to the opening in the spout E, except when the pipe G is depressed as
hereinafter described. The upper end of the pipe G is provided with a screw cap N
furnished at one side with an opening S in communication with the interior of the
said pipe. Mis a spring, the upper end of which bears against the lower end of the
screw cap N, and its lower end against a washer that serves to close the upper end of
the hole in the plug F around pipe G. The spring M. serves to keep the pipe G
normally in the position shown in the drawing, that is with valve G2 closed. is a
lever pivotted at to the cap '; by depressing this lover the pipe G can be depressed
to open valve G² and allow liquid under pressure in the bottle to escape by the
spout E. Qis a metal ring placed around the upper part of the cap C and screwed to
a chamber 0 provided with an inlet nozzle P. The metal ring Q serves to secure a
washer of elastic material to the chamber O, so that when the bottle is being
charged with gas in the manner hereinafter described, the said washer ensures a gas-
tight joint between the chamber O and a flange on the cap C. When the bottle has
been so charged, the chamber with ring Q are removed. K is a tube which may be
of glass through which gas under pressure enters the bottle and through which the
liquid is afterwards forced from the bottle it is encircled at its upper end by an
india-rubber ring L attached to a washer T of similar material interposed between the
top of the bottle and a shoukler in the cap C. The washer T and ring I of india-
rubber, prevent the liquid within the bottle coming into contact with the metal
cap C
Referring to Figs. 3 and 4. 1, 2, and 3 are three cylinders which are charged with
"glowed" charcoal so as to constitute gas filters; they are carried by a frame or
standards 4. 5 is a tube for conveying gas, such as carbonic acid gas, from any
suitable apparatus wherein it is produced to one end of the cylinder 1; it is provided
with a valve or cock 6. 7 is a pipe in communication with the cylinders 1, 2, and 3
at the front by connections provided with valves 8, 9, 10 respectively. 11 is a pressure
gauge for indicating the pressure in the pipe 7 and cylinder 1, and 12 and 13 are
pressure gauges for indicating the pressure within the cylinders 2 and 3 respectively.
14 and 15 are pipes leading from the rear ends of the cylinders 2 and 3 respectively:
they are provided with valves or cocks 16 and 17, and are connected to a common
pipe 18. This pipe 18 is in communication with one end of a hollow shaft 19, pre-
ferably of copper, carried in suitable standards 20. 21 is a valve or cock for
controlling the passage of gas through the pipe 18. 22 is a hole in the front end of
the hollow shaft 19; it is closed by a removable screw plug 23 when the apparatus is
in use.
24, 24 are a series of outlet holes or openings through the wall of the hollow
Into these holes or openings nozzles (see Fig. 1) are placed when syphon
bottles such as A are to be charged with gas. The bottles are maintained in the
positions shown in Figs. 3 and 4 by plates 25 and springs 25 carried by a suitable
framework 26 as shown fixed to the exterior of the hollow shaft 19, 27, 27 are levers
For withdrawing the plates 25 from the ends of the bottles against the action of the
springs 25 when the bottles are to be removed from the machine. 19° is a crank
handle secured to the front end of the hollow shaft 19 by which such shaft may be
rotated. The end of the pipe 18 is united to a T shaped pipe 18 which is connected
to the end of the shaft 19 by a hollow rod 81 provided at its inner end with an
enlarged curved part adapted to bear against the correspondingly formed end of the
shaft 19 as shown to allow of the said shaft rotating without affecting the flow of gas.
32 is a screw nut for keeping the enlarged part of the rod 31 in close contact with the
end of the shaft 19. 83 is a rod or bracket for carrying the T shaped pipe 18".
shaft 19.
When charging syphon bottles a pressure of 14 atmospheres in the cylinder 1. and
of 8 atmospheres in the cylinder 2 will be found advantageous. The pressures may
be regulated by the valves or cocks 8 and 9 and by the pressure gauges 11 and 12
respectively.

page_text: The operation of charging with gas a series of syphon bottles such as described is as
follows The bottles are filled with water or other liquid and then applied to the
hollow shaft 19 as hereinbefore described. The cylinders 1 and 2 are charged with
gas to their respective pressures of 14 and atmospheres and the gas at S atmospheres
pressure stands at cock 21. The hollow shaft 19 is then freed from air by removing
the screw plug 23 and allowing carbonic acid gas, passing through the cock 21 and
pipe 18 to blow through it. The screw plug 23 is then replaced and the hollow
Shaft 19 rotated by means of the crank handle 19° for a short time, say for about
15 minutes, which time will usually suffice to charge the bottles when the pressures of
gas hereinbefore mentioned are employed. Valve 21 is then closed, the botiles are
removed from the machine, and chambers O (Fig. 8) taken off the bottles, the gas
therein being prevented from escaping by the rings or valves G₁ (Fig. 1).
When the machinery or apparatus is to be adapted for filling other bottles such as
those closed by ball stoppers, the holes 24 in the shaft 19 are screw threaded and fitted
with a short tube 28 (Fig. 5); each of these tubes is provided with a washer 29 of
suitable material such as india-rubber.
Each washer serves to ensure a gas-tight joint between the shaft 19 and the
mouth A¹ of a bottle when placed in position in the machine. The outlet 29" of each
tube 28 is located at one side thereof and is closed by a ring 30 of suitable elastic
material such as india-rubber. The method of charging liquid contained in bottles of
the kind mentioned with gas under pressure is similar to that herein before described
with respect to syphon bottles but a less pressure, usually about 5 atmospheres, will
suffice. For this purpose the filtering cylinders 1 and 3 are employed, communi-
cation with cylinder being established by opening valves 10 and 17, whilst
communication with cylinder 2 is cut off by closing valves 9 and 16. The required
pressure in cylinder 3 is obtained by the use of the valve 10 and pressure gauge 13.
31 are blocks of material such as wood interposed between the ends of the bottles and
the plates 25. When charged the bottles are removed, being kept inverted so that the
stoppers may be caused to close by the pressure of the gas within. The rings 30
prevent entrance of dirt or other matter into the shaft 19 when the bottles are
removed.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, we declare that what we claim is :—
1. A syphon botile for aerated liquids constructed and arranged substantially as
hereinbefore described with reference to Figs. 1 and 2 for the purpose set forth.
