Improvements in the Method of and Apparatus for Aerating and
Clarifying Liquids.
I HENRY HILL of 30 Herne Hill London Brewer do hereby declare the nature
of this invention to be as follows:-
By means of a perforated trough the liquid falls in streams into a vessel. By
means of a tube provided with float or counterbalance the surface liquid is drawn
through an intermediate connector and regulating cock into a trough: this trough
is provided with interceptors so contrived and placed as to cause an alternate
upward and downward flow of the liquid in transit.
The liquid may be heated or cooled in its passage through this trough by means
of a jacket or pipe.

1 HENRY HILL of No. 30 Herne Hill London in the County of Surrey
Brewer 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 :-
The object of this invention is to expose liquids to the oxidising action of the air
and to draw off liquids contained in open or covered vessels from the upper surface
by means of a pipe or tube with adjustable buoy or counter balance or both
attached the said tube communicating through a closed chamber or connector
affixed to the bottom or lower part of the vessel with the outlet which latter is
provided with a sluice or cock which can be set to regulate the outflow. By this
means I am enabled to draw off from the upper surface that portion of the liquid
which is exposed to the air and which has become oxidised and clarified
thereby.
In order to obtain a larger oxidation and clarifying effect I use a trough placed
above the collecting vessel provided with a strainer if necessary the sides and
bottom of which are perforated so as to cause the liquid which flows along it to fall
in streams or sheets into the vessel in which the tube apparatus is fixed.
And also in order to obtain a further oxidation and clarification I cause the
liquid so drawn off to traverse an open or covered shallow or deep trough with or
without divisions or partial interceptors so constructed as to cause the liquid
to flow alternately upwards and downwards or to ripple in iis course
outlet.
to the
This trough is when necessary provided with a case or jacket or pipe through
which hot or cold water or other liquid may be passed in order to raise or lower or
otherwise regulate the temperature of the liquid in transit the floor of this trough
may be plain fluted or corrugated.

page_text: One of the specific purposes to which this invention is applied is the more perfect
oxidation and clarification of brewer's worts while at a high temperature and the
substitution of deep vessels (with attendant large saving of space) for shallow
"coolers" of large area.
Suitable arrangements of inlet and outlet are also provided for admitting
when and as required only purified air to be brought into contact with the
liquid.
In order to the perfect understanding of the herein described apparatus and the
manner in which it operates reference may be made to the accompanying
drawings in section (Fig. 1) and in plan (Fig. 2) the letters in both figures
indicating the same parts namely.
