PROVISIONAL SPECIFICATION.
Improvements in and relating to Apparatus for Aërating Liquids.
I, JULIUS LEOPOLD MENDL, of Üllöi út 144, Buda-Pesth, in the Kingdom
of Hungary Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus designed for aerating liquids, more especially
for manufacturing soda water, and comprises improved devices whereby the water
or other liquid is saturated with carbonic acid either in the liquid or in the gaseous
state.
In carrying my said invention into effect I provide a mixing vessel which may
be made of cylindrical or other shape and into which the carbonic acid passes.
For manufacturing soda water the water is pumped in through an opening and
passes into a tube the upper end of which is closed by a piston. This piston is
partly hollowed out and provided with lateral openings.
When the pump is set in action the water which enters raises the said piston
thereby uncovering the lateral openings otherwise closed by the said tube, and the
water passes with great force into the vessel on the walls of which it is atomized.
After the water which was forced in by the stroke of the pump has passed
these openings the piston sinks by its own weight and by the weight of a disc,
suspension rods, and a perforated disc, and lastly by the action of a spring. As a
consequence the water contained in the lower part of the vessel is forced through
the small openings in the last-mentioned disc, being thrown upwards in the form of
jets and again atomized.
Now the raising and lowering of the said piston is repeated in every stroke of
the pump so that an intimate contact will be established between the carbonic acid
and the atomized water, thus causing the former to be taken up by the latter as
rapidly as possible.
I provide a water gauge and an aperture through which the finished soda
water leaves the vessel.
The advantages of this improved apparatus are in the first place the suppres-
sion of a stuffing box, as no part of the mixing device extends to the outside of the
vessel, and in the second place a considerably more intimate mixing than is possible
by the well-known vanes.

Improvements in and relating to Apparatus for Aërating Liquids.
I, JULIUS LEOPOLD MENDL, of Ültöi út 144 Buda-Pesth, in the Kingdom of
Hungary, 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:-
My invention relates to apparatus designed for aërating liquids, more especially

page_text: for manufacturing soda water, and comprises improved devices whereby the water
or other liquid is saturated with carbonic acid, either in the liquid or in the gaseous
state.
In the accompanying drawing
Figure 1 is a vertical section of my improved apparatus and
Figure 2 is an horizontal section of the same.
In carrying my said invention into effect I provide a mixing vessel A which
may be of cylindrical or other shape and into which the carbonic acid a passes.
This
For manufacturing soda water the water is pumped in through an opening b
and passes into a tube B the upper end of which is closed by a piston c.
piston c is partly hollowed out and provided with lateral openings e.
When the pump is set in action the water which enters raises the said piston c,
thereby uncovering the lateral openings e otherwise closed by the said tube B,
and the water passes with great force into the vessel A, on the walls of which it
is atomized.
After the water which was forced in by a stroke of the pump has passed these
openings the piston sinks by its own weight and by the weight of a disc d, suspen-
sion rods, ff and a perforated disc g, and lastly by the action of a spring h. As a
consequence the water contained in the lower part of the vessel A is forced through
the small openings in the last-mentioned disc, 9 being thrown upwards in the form
of jets and again atomized.
Now the raising and lowering of the said piston is repeated in every stroke of
the pump so that an intimate contact will be established between the carbonic acid
and the atomized water, thus causing the former to be taken up by the latter as
rapidly as possible.
The carbonic acid is introduced into the vessel at a, the pipe a¹ in which the
guide-rod c¹ of the piston works being widened in such a manner that the carbonic
acid is enabled to enter in spite of the reciprocating movement of the said guide-
rod.
I provide a water gauge. K and an aperture through which the finished soda
water leaves the vessel.
The advantages of this improved apparatus are in the first place the suppres-
sion of a stuffing box, as no part of the mixing device extends to the outside of the
vessel, and in the second place a considerably more intimate mixing than is possible
by the well-known vanes.
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
A mixing vessel for aërating liquids substantially characterized thereby that
in a vessel, a pistone a spring a disc g are so arranged on a guide-rod c' that the
said piston is set in a reciprocating movement on the one hand by the action of the
liquid pumped in at b and on the other hand by the action of the said spring (h);
this reciprocating movement causing the liquid to be aèrated, to be alternately
forced through orifices provided in the piston c and in the disc g and to be atomized
on the wall of the vessel, for the purpose of obtaining a ready saturation of the
liquid with carbonic acid the latter being introduced through a suitable orifice at
the top of the vessel.
