Improvements in and Apparatus for the Manufacture of Effervescing
Beverages.
I, WILHELM BITTER of 21 Bahnhofstrasse, Bielefeld in the Empire of
Germany, Manufacturer, 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 the manufacture of effervescing beverages and to
apparatus employed in connection with the said manufacture whereby a rapid and
thorough impregnation of the liquid is obtained. The new process of manufacture
consists essentially in causing the liquid to come in contact with carbonic acid
whilst in a finely divided condition and thereby enabling it to become quickly and
completely saturated with the gas. This is accomplished by the aid of apparatus
of improved construction as hereinafter described.
And in order that my said invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the
several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 of the accompanying drawings represents the apparatus partly in
elevation and partly in vertical section.
Figure 2 represents a part of the apparatus in horizontal section, the section
being taken on the line C-D Figure 1.
Figure 3 represents the apparatus in plan.
The apparatus is provided with an impregnating cylinder or chamber a connected
on the one hand with a vessel or chamber i containing liquid carbonic acid and on
the other hand with a bottle h for the reception of the liquid to be impregnated.
The carbonic acid chamber i is provided with a reducing valve k and a pressure
gauge and communicates with the impregnating cylinder through a rubber tube l.
The bottle his supported upon a plate g and is pressed by means of a screw f
against a mouth piece e communicating with the chamber a through a valve d.
The impregnating chamber a the valve d the plate g and screw fare supported by
a bar or arm n connected at c with a hollow shaft or spindle o rotating in a bearing p
so that the bar or arm n with all the parts connected therewith can revolve with
the shaft o working in the bearing without causing any leakage at the connections.
The bearing p is carried by a pillar or stand 6 having a foot or base plate q and
by means of a strap or collar r supports the carbonic acid vessel i firmly in position
and also carries all the other parts of the apparatus.
The impregnating cylinder a is filled with small pieces of a neutral material such
as porcelain, earthenware or glass and is provided at both ends with a perforated
false bottom or filter s which prevents any impurities in or on the materials in the
vessel from contaminating the liquid.
The action of the apparatus is as follows viz.: The valve d being closed carbonic
acid is caused to pass from the chamber i through the pressure reducing valve k
tube and hollow shaft o into the impregnating vessel a the latter being provided
with a cock s¹ which is opened in order to allow the air in the vessel to escape.
When all the atmospheric air has been expelled from the chamber a this cock is
closed. The bottle containing the liquid which is to be impregnated with
carbonic acid being secured in position between the plate g and valved by means
of the screw f the valve is opened and the cylinder a together with the bottle
are caused to revolve upon the shaft o through about 180 degrees so that the bottle
is inverted upon the impregnating vessel and automatically discharges its contents
into the said vessel in which the liquid flows in thin streams or trickles over the

page_text: surfaces of the pieces of glass or other materials placed therein. The parts are
then restored to their original position and the liquid being now completely
impregnated with carbonic acid flows back into the bottle h. The valve d is then
closed and the bottle / being removed a fresh bottle is substituted in its place so
that the operations may be repeated with another bottleful of liquid.
The liquid is finely divided by the action of the materials placed in the
impregnating chamber and is thereby caused to present an extensive surface to the
action of the gas to be absorbed. A like result may be obtained by arranging a
considerable number of perforated partitions or sieves in the interior of the
impregnating cylinder so as to divide the liquid into a large number of thin
streams.
The process of manufacture may be carried out in practice with the aid of a
non rotating or fixed impregnating cylinder or vessel the liquid being introduced at
the upper part and drawn off at the bottom.
The apparatus according to this invention is well adapted for manufacturing
effervescing beverages on a small scale and the peculiar arrangement of the
impregnating vessel presents the important advantage that one revolution of the
impregnating vessel and bottle which is performed with great ease is sufficient
to impregnate the liquid without any other manipulation.
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. Manufacturing effervescing beverages by causing the liquid which is to be
impregnated with gas to flow or trickle over neutral materials arranged so as to
present a relatively extensive surface the liquid being at the same time subjected
to the direct action or pressure of the carbonic acid in order to quickly and
thoroughly impregnate the said liquid substantially as hereinbefore described.
2. For manufacturing effervescing beverages as hereinbefore described and
claimed an apparatus provided with a rotatable impregnating cylinder containing
neutral materials being connected with the carbonic acid vessel and with the bottle
or vessel for the reception of the liquid to be impregnated which liquid by rotating
the impregnating cylinder is caused to enter the latter being discharged therefrom
in a thoroughly impregnated condition when the revolving parts are returned to
their original position substantially as hereinbefore described with reference to the
accompanying drawings.
3. In the apparatus for manufacturing effervescing beverages referred to in the
preceding claiming clause an impregnating cylinder provided internally with a
series of superposed sieves or perforated partitions whereby the liquid is divided
into a number of thin streams and enabled to rapidly and effectually absorb the
carbonic acid substantially as hereinbefore described.
4. The arrangements and combinations of parts constituting improved apparatus
for the manufacture of effervescing beverages substantially as hereinbefore
described with reference to the accompanying drawings.
