COMPLETE SPECIFICATION.
Apparatus for the Electrolytic Treatment of Liquids.
I, NEWNHAM BROWNE, of 73 Cheapside in the City of London, Chartered
Patent Agent, do hereby declare the nature of this invention and in what manner
the same is to be performed which has been communicated to me by Alfred
Vogelsang, Engineer, of Dresden in the Empire of Germany, to be particularly
described and ascertained in and by the following statement :-
This apparatus for the electrolytic treatment of liquids is designed with a view
of exposing the liquid to be treated to as large a number of electrodes as possible
in a small space and of permitting the apparatus to be readily cleaned.
In the accompanying drawings
Fig. 1, shows such an apparatus in upright form, Fig. 2, its horizontal form, both
figures being vertical sections.
In each case a is a casing of wood, glass or other non conducting material, whose
length or height, as the case may be, is greater than its width.
The construction illustrated in Fig. 1, shows the casing a with its bottom inclined
longitudinally. The ends are internally lined with an electrode 6 of metal or other
conductor of electricity. Between the ends are fitted a series of electrode plates b
in greater or less number according to the size of the apparatus. These plates
are equidistant and so arranged as to fit closely to the sides of the casing a,
their upper and lower edges however are alternately higher and lower, the lower
plates have their inferior edge fitting the bottom of the casing a.
Thus a long
channel ascending and descending between the electrodes 6 is formed, the several
parts of which are in connection alternately at the top and bottom of the two
electrodes confining the same.
In the construction shown in Fig. 2, an analogous channel is formed by making
the electrodes b somewhat smaller than the clear internal measure of the casing a
and fitting one edge of the electrodes alternately to the right hand side and left
hand side of the casing so that at the opposite edges and the side of the casing
nearest thereto open spaces are alternately formed.
By these open spaces communication is established between the several compart-
ments formed each by two electrodes.
The operation of such an apparatus is as follows:-
:―
The liquid to be electrolitically treated is admitted to the highest compartment
and flows either over and under the several electrodes and between them as in the
construction shewn in Fig. 1, or between them from left to right and right to left
downwards as in the construction illustrated in Fig. 2, passing through the spaces
at the ends of the electrodes b.
In the long path thus traversed by the liquid the electric current entering at +
and flowing through the several electrodes is constantly traversing the liquid and
acts upon the latter in the required manner and from the last compartment the
liquid is drawn off by a pipe c for storage or use as the case may be. The current
leaves the apparatus at the part marked
For cleaning every pair of compartments in Fig. 1, and the last compartment in
Fig. 2, are shown fitted with apertures d suitably closed. When these are opened
the contents flow out and the apparatus may be rinsed with water.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
:-
An apparatus for the electrolytic treatment of liquids, characterized by a
casing a of non conducting material and either horizontal with a sloping bottom

page_text: (Fig. 1) or upright (Fig. 2) in which equidistant electrodes 6 are so arranged that
the liquid admitted for electrolytic treatment passes either up and down (as in
Fig. 1) or from right to left and vice versa (as in Fig. 2) the current flowing from
one electrode to the other continuously traversing the liquid and producing the
required effect upon the same.
