THOMAS HOWELL WILLIAMS IDRIS of Pratt Street Camden Town in the
County of Middlesex Mineral Water Manufacturer and Manufacturing Chemist
and RICHARD HooSON GRIFFITH of the same place Syphon Maker, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
Our invention consists of an Improved Method of Filling Syphons and other
Vessels with Aerated and Gas charged Waters and Beverages. The object of our
Invention is to enable Syphons Bottles and other Receptacles requiring to be
charged with Aürated or Gas charged Waters and Beverages to be so charged
at a fairly uniform pressure capable of regulation at pleasure and at the same time.
to prevent unnecessary waste. The method by which we attain this object is by
means of a. Secondary closed Vessel charged at the pressure corresponding to that
at which the Syphon Bottle or Receptacle when filled is required ultimately to
stand.
We can best illustrate our meaning by taking the example of a Syphon Bottle.
According to the present method of filling such Syphons which is commonly
adopted a Closed Vessel usually a Cylinder is filled with the Aerated or Gas charged
Beverage at an initial pressure considerably higher than the ultimate pressure
required in the Syphon to be filled. This high pressure in the primary Vessel or
Cylinder is necessary both for the rapid saturation of the Water with Gas and for
testing the pressure which the Syphon in course of being filled is able to bear with
safety such pressure being afterwards reduced as hereafter explained. The initial
pressure above referred to is generally from about 160 to 200 lbs. to the Square
Inch and such initial pressure is usually reduced by one or more releases of Gas
from the Syphon in course of being filled technically called Snifting so that, the
ultimate pressure therein is usually about 50% less and varies considerably, being
dependent upon the Skill of the Operator the state of the valve of the Syphon and
other causes.
The pressure in the Syphon when filled under the existing methods may be as
low as 40 lbs. or as high as 150 lbs. to the Square Inch the former being too low
and the latter too high for the desired effect in ordinary use.
It is found in practice that an ultimate pressure in the Syphon of about 100 lbs.
to the square inch is most suitable to ensure the complete. release of the contents
in a satisfactory manner.
A Syphon has hitherto been usually charged by being attached in any of the
ordinary ways to a nozzle attached to a pipe leading from the primary Vessel or
Cylinder above referred to such pipe having a Valve. intervening between such
primary Vessel or Cylinder and the nozzle to which the Syphon is attached and in
the case of Bottle filling Machines. another Valve between such Nozzle and the

page_text: exit to the open air both capable of being opened and closed by the Operator at
will. The Syphon having been partially filled the superfluous Gas has to be allowed
to escape and with it a certain amount of the Water or Beverage this being done
by cutting off the flow from the primary Cylinder by closing the valve and opening
the Valve of the Syphon or the Second Valve as the case might be.
This operation generally requires to be repeated several times before the Filling
is completed and is called Snifting as stated above. The ultimate pressure on the
Syphon when full therefore under the method above referred to was practically
mere guess work and varied accordingly, being sometimes in excess of and some-
times below what was desired.
Moreover under the above described system the gas and fluid ejected in the
process of snifting was wasted.
In order to remedy the above mentioned uncertainty of pressure in the filled
Syphon we use in addition to the primary vessel or cylinder another subsidiary or
Secondary closed vessel preferably a Cylinder which we maintain uniformly at the
pressure we desire to be the ultimate pressure in the filled Syphon or Syphons
preferably at 100 lbs. to the square inch as mentioned above. This uniformity of
pressure can be. maintained in such Secondary Vessel or Cylinder by a Safety
Valve or other suitable means the primary vessel or cylinder being also usually
supplied with a safety valve.
.
From the Primary Cylinder a pipe leads into a Chamber having a Nozzle attached
thereto capable of receiving the Spout of the Syphon such Nozzle having a Ring of
seating composed of Leather or other suitable material therein such as is generally
used for the end of the Wall of the Spout of the Syphon to press up against and
80 prevent the escape of the passing fluid or Gas. From this Chamber another pipe
leads out into the Secondary Cylinder.
In or near this Chamber the first mentioned pipe is furnished with a Valve
capable of regulating and when desired cutting off the flow from the primary
Cylinder and within easy reach of the Operator.
In or near the said Chamber the second mentioned pipe is also furnished with a
valve capable of opening or closing such pipe which valve is intended to be used
for Snifting purposes as hereinafter described and is within easy reach of the
Operator. Both of these Valves are worked by Levers or other suitable means and
they may if desired be so arranged that they are both operated by one and the
same Lever.
The first mentioned pipe may if desired be furnished with an additional valve
preferably placed near to the primary Vessel or Cylinder.
Referring to the accompanying Drawing A is the primary Vessel or Cylinder
which is a Vessel of the ordinary character and with the ordinary fittings used by
Mineral Water Manufacturers for the Manufacture of Aërated Beverages B is the
Secondary Vessel or Cylinder.
C is the Pipe leading from A to the Filling Chamber D.
D is the Pipe leading from the Filling Chamber to B.
E is the Filling Chamber.
F is the Syphon in position for filling.
G is the Receptacle for the Syphon.
H is the Safety Shield of same Receptacle.
K is the Handle for pressing the Lever of the Syphon and opening the Syphon
Valve.
L is a Handle for operating the Valves closing the Pipes C and D.
a, is the Pressure Guage on A.
bis the Pressure Guage on B.
c, is the Safety Valve on A.
d, is the Safety Valve on B.
e,
is the Nozzle for receiving the Syphon Spout.
f, is a Valve for opening and closing the pipe C.
g, is a Valve for opening and closing the pipe D,

page_text: h, is another Valve in the pipe C which is not absolutely necessary but convenient.
No Novelty is claimed for the various items composing the Apparatus as they
are such as are ordinarily used by Mineral Water Manufacturers and others.
The Method of using the Apparatus is as follows:
The Syphon F being placed in the Receptacle G for the purpose with its Spout
in the Nozzle, e, and the Lever so arranged as to be operated by the Lever K and
the Cage or Shield H having been closed and the Valve at, h, if it exists being
open and the Valve, g, closed the Valve at, f, is opened to admit the charged
Water from A into the Chamber E and thence through the Nozzle, e, into the
Syphon, the Valve, f, is then closed and the Valve, g, is opened for a sufficient
time for Snifting purposes.
Then 9, is closed and f, reopened and the same operations are repeated until the
Syphon is full. The two Valves f and g, are shown in the Drawing as being
operated by the same Handle L but this although convenient for the Operator is
not absolutely necessary.
This Apparatus may be adapted to the purpose of filling more than one Syphon
by providing the Chamber E with several Nozzles or by having more than one
Chamber each Chamber being connected with the Cylinder A and also with the
Cylinder B by Pipes and Valves in the same way as the Chamber E.
In lieu of Chamber E and the Pipe D the Pipe C may be continued from the
Receptacle A to the Receptacle B with a Charging Nozzle provided for the reception
of the Spout of the Syphon at an intermediate point between the two Receptacles
but with a Valve on either side of such Nozzle to perform the functions of
Valves fand g, herein before described.
If it is desired to use this modification to fill more than one Syphon at a time
several Nozzles may be employed. The Waste Gas and Water collected in the
Secondary Vessel or Cylinder by the operation of Snifting may be used for filling
other Receptacles at lower pressure and for a variety of other purposes.
We have mentioned a Syphon Bottle by way of illustration but our Invention
is equally applicable to the filling of any Bottle or Receptacle requiring to be
filled with any Aerated or Gas charged Beverage at a certain fixed and known
pressure such as Beer Champagne Mineral Waters and the like but instead of the
nozzle C receiving the neck or other orifice of such bottle or receptacle it may be
preferable to elongate the nozzle e for insertion into such or other orifice as above
mentioned and instead of providing an internal annular seating to cover the nozzle
with a suitable elastic covering.
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
The improved method of filling Syphons Bottles and Receptacles with Aerated
Waters or other Gas charged Beverages at a fairly uniform pressure of any desired
degree by means of the combination of a Secondary closed vessel charged to the
desired pressure with the primary Vessel used in filling such Syphons Bottles and
Receptacles substantially in manner hereinbefore described.
