COMPLETE SPECIFICATION.
A New or Improved Emulsifying Apparatus for Aromatizing or
Flavouring the Carbonic Acid Gas destined to Aerate Water
and other Liquid Substances.
I CLEMENT PROUT NOEL HUSK 85 Fore Street in the City of London
England, Chemist, 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 :-
My invention relates to a new or improved emulsifying apparatus for aromatizing
or flavouring the carbonic acid gas used to aerate water and other liquid
substances and consists chiefly of improvements in the apparatus described in the
Specification of Her Majesty's Royal Letters Patent No. 16254 dated the 25th
day of August 1894 granted to Alexander Mitchell.
In this specification there is described a process for aromatizing or flavouring
aerated beverages that is to say for producing the necessary liquor or emulsion
which is needed to impart the required aroma or taste to the carbonic acid gas
destined to aerate beverages without any waste of essential oils and spirits as had
hitherto invariably been the case.
By way of illustrating the method of carrying the said process into practice an
apparatus is shown in the drawings forming part of this specification which was to
be placed, in the plant of mineral water works, between the apparatus producing
the carbonic acid gas and the pump of the aerating and bottling machine. This
apparatus however is deficient inasmuch as it is not air tight, the, arrangement of
its parts is neither convenient or practical, and several of the fittings do not answer
the purpose for which they were intended.
My invention has for its object to remedy these defects and to design a thoroughly
air tight apparatus of improved construction and of practical use for mineral
water works.
In the accompanying drawings
Fig. 1. is a plan and Fig. 2. a sectional elevation of my improved apparatus,
Fig. 3. are views illustrating three modifications in the construction of my
improved valve and
Fig. 4. shows another valve.
My improved apparatus consists of three cylinders A, B, C, preferably of glass
or other suitable incorredible material, the upper and lower peripheries of which
are located in a corresponding groove of the covers C₁ secured together by the
rods and suitable nuts. The upper and lower covers are centrally perforated to
receive the taps t³ t t fixed to the bulbs 1. 1' 12 connected to other taps t² 1 to
surmounted by funnels fff and to pipes e e¹ e respectively. The pipes e el e
are fitted with taps jjj which act as inlets as well as draw off cocks. m is the
admission pipe for the carbonic acid gâs provided with a tap t¹ connected to the
pipe a descending into the cylinder A and terminated with a nozzle B¹.
The cylinders A B and B C communicate together by means of the pipes b and c
descending therein and likewise terminated by a nozzle B. d is the outlet pipe
of the apparatus and is provided with a tap 8 and a valve for preventing back
pressure from the pumps in the mineral water works.
ບ.
P is a bye pass or pipe provided with an inlet tap t and an outlet valve it
serves to convey the unimpregnated carbonic acid gas directly to the pumps
aforesaid whenever required. s is a vent tap.

page_text: The details of the valves are shown in Fig. 3. wherein is a valve case 9 a
circular flange against which bears the flap hinged at h; this valve may be
weighted in some cases as shown at k or may be used in a reverse position in
which the beating of the flap is limited by a stop q secured to the case i.
Fig. 4. shows another arrangement of valve that is to say a ball valve wherein i
is the casing w is a wire cage in which the ball o can travel, this cage being slightly
inclined as shown to ensure of the closing of the valve opening by the ball which
bears against it. This ball is. ground to fit this opening and may be made of
glass or any other incorrodible metal or material.
The valves shown in Fig. 2 may be of either of the constructions shown in
Figs. 3. and 4. by preference but any other suitable back pressure valve would also
answer the purpose.
My apparatus operates as follows: The cylinders A B having been previously
filled with water to the desired height according to the quantity of emulsion
required carbonic acid gas supplied by any suitable carbonic gas generator, is
allowed to enter the cylinders at m by opening the tap t' while the tap t remains
closed. The gas descends along the pipe a and issues into the cylinder A through
the nozzle B which is finely perforated so as to devide the gas in the form of a
very fine spray which ascends through the water, the gas escaping subsequently
through the pipe in order to reach through a similar nozzle B the cylinder B
whence it proceeds in the same manner into the cylinder C. The latter contains
spirits of wine for the purpose of recovering from the gas any particles of
undissolved oil which it may have carried away whereupon the gas escapes through
the pipe n on its way to the pumps which force it into what is called in the trade,
the carbonating cylinder or condenser not shown on the drawings. The carbonic
acid gas passing in the manner above described through the cylinders A and B
impregnates the water contained in the said cylinders with the required oil fed
through the funnels ff whence the taps t2 t being opened it enters the bulbs or
receivers II' the object of which is to prevent by the aid of the taps to to the
admission of atmospheric air into the apparatus. The taps and t* being now
closed the taps t t are opened and the oil drops into the cylinders A and B
where it mixes with the water and is emulsified by the action of the carbonic
acid gas. The cylinder C is supplied with spirits poured through the funnel f
into the bulb I after the tap t has been opened. The tap t being closed, the tap t
is opened which allows the spirit to fall into the cylinder or recovering vessel C
wherein the carbonic acid gas is freed from all undissolved particles of oil which
may have been carried over this strongly aromatized gas proceeding now through n
into the condenser wherein it: aromatizes as well as it aerates the water therein
contained. The inlet taps jj fixed to the pipes e e¹ serve to fill the cylinders A
and B with water from a hose when the veut taps is open, and at the same time
act as draw off taps to employ the said vessels. The cylinder C which contains
the spirits of wine may be filled either through the top funnel ƒ in the manner
above set forth or through the tap fixed to the pipe e2 in the same manner as for
the cylinders A and B. The impregnated spirit may be used as scent for various
industries.
vvare valves used to prevent the carbonic acid gas from being forced back into
the apparatus. The pipe P connected with the tapt serves to supply unimpregnated
gas directly to the condensers when the apparatus is not made use of. The residual
water treated in the manner described, in the cylinders A and B may be used for
the production of sweetmeats, the scenting of soaps and for various other
purposes.
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 :-
1. The emulsifying apparatus for charging the carbonic acid gas used to aerate

page_text: water, with the required aroma flavour or essential oil and for other purposes,
arranged constructed and operating substantially as herein described and shown.
2. In emulsifying apparatus such as above claimed the improved construction of
valves shown in Figs. 3 and 4 of the accompanying drawings substantially as herein
described.
