COMPLETE SPECIFICATION.
Improvements relating to Clearing and Purifying Apparatus for
Liquids.
I, HERMANN PESCHGES, Engineer of 14 Französische Strasse Potsdam, in the
Kingdom of Prussia, German Empire, do hereby declare the nature of my inven-
tion and in what manner the same is performed to be particularly described
and ascertained in and by the following statement:-
The present invention consists of a clearing and purifying apparatus, founded
on the syphon principle, and the apparatus is constructed in such a manner that the
same may be employed on a large scale without an air pump and that the impurities
deposited in the lower cistern may be easily and conveniently removed without the
aid of a scum pump.
The apparatus consists mainly of an upper cistern having a filter therein and a
lower cistern connected to the said upper cistern, an air chamber being arranged
above the upper cistern to extract the air from the liquid under treatment, suitable
pipes and connections being arranged between the said cisterns and the liquid to be
purified as herein after more particularly described.
And in order to make my present Specification more easily intelligible, reference
is had to the accompanying drawing showing an elevation of the apparatus.
The
The apparatus consists of the lower cistern a, the upper cistern 6 having a filter
arranged therein and the air chamber c, the two cisterns being connected by means
of pipes d and d¹ and the upper cistern 6 with the air chamber c by the pipe e. The
air chamber c is provided with an inlet f. The apparatus has further an inlet pipe g
to the lower cistern a and an outlet pipe h communicating with the pipe e.
inlet pipe g has a valve k, the pipes d and d¹ valves i and and the outlet pipe ha
valve. The inlet to the air chamber c has a cock m and the connection e a cock n.
The cistern a is provided with an outlet cock o and an air cock p, the cistern band
the air chamber c having air cocks
and r.

The operation of the apparatus is as follows:-
are.
In starting work the valves k and I and the cock o are closed, the other cocks
and valves remaining open. The apparatus may be filled through the funnel above
the filter f, either direct from the water supply or by means of a hand pump for
the smaller apparatus. After this has been accomplished, the valves k and
opened and all the other valves and cocks, with the exception of and n closed.
Thus water or any other liquid entering the apparatus at s will flow out continuously
att whilst the air contained in the same will pass into the air chamber c and all
other impurities will be detained in the cistern a. As soon as the chamber c is
filled with air, the valve n should be closed and the cocks m and r opened, the
chamber may then be refilled and the apparatus continue working.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is performed, I declare that what I claim is :-
1. A clearing and filtering apparatus consisting of the lower cistern a, the upper
cistern 6 having a filter, and communicating with a, and the pipe connections g
and arranged substantially as described and shown.
2. The combination of the lower cistern a, the upper cistern 6 having a filter,
the air chamber c having inlet and cock, pipe connections, valves and cocks between
the said cisterns and the air chamber, and liquid to be treated, all parts arranged
