PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Electrolysing Chloride Solutions
Employed for Disinfecting.
We, EUGENE HERMITE, EDWARD JAMES PATERSON, and CHARLES FRIEND
COOPER, all of Pownall Road, Dalston, in the County of Middlesex, Electrical
Engineers, do hereby declare the nature of this invention to be as follows:
-
This invention relates to apparatus for electrolysing chloride solutions, so
constructed and arranged that it can be used in private houses or in establishments
of any kind where there are closets, urinals, sinks drains or the like requiring
disinfecting, such houses or establishments being supplied with a chloride solution
which may be sea water, or, where sea water is not available, it may be a solution
of sodium chloride and magnesium chloride. The electrolysing apparatus according
to this invention consists of a number of sections or elements arranged to act
together, the number of elements being varied to suit the amount of electrolysing
to be effected and the electrical energy available. Each element consists of an
outer tube of glass or other insulating material containing within it a tube of
zine and, centrally within the zinc, a wire of platinum. The outer tube has at
each end a plug of caoutchouc or the like through the one of which pass conducting
wires to the zinc and platinum respectively, and through both of which pass glass
or ceramic tubes for ingress and egress of solution to be treated. A number of
these elements are electrically connected in series, the first zine being connected to
the negative and the last platinum to the positive terminal of a source of electricity,
which may be the supply service for electric lighting. The tube leading into the
first element leads from the supply cistern of chloride solution, which, after passing
from element to element and so becoming electrolysed, is led finally to the supply
cistern of the closet, urinal or other place requiring disinfectant. The liquid,
instead of passing through all the elements in succession, may pass through all or
any number of them simultaneously. The process may go on continuously, but,
in order to economise electrical energy, it is preferred to give an intermittent
supply of disinfectant by siphon tanks fed by ball cocks, connecting the ball cock
to an electric switch which closes the circuit for the electrolysing apparatus only
during the time that the ball cock remains open, and that the liquid is flowing.
When the ball cock closes, the circuit of the electrolyser is opened, and no
electrical energy is expended until the next flow of liquid takes place.
The construction of each element may be simplified by substituting a tube of
galvanised iron for the zinc and the outer tube containing it, and mounting these
iron tubes so as to be insulated.

Improvements in Apparatus for Electrolysing Chloride Solutions

We, EUGENE HERMITE, EDWARD JAMES PATERSON, and CHARLES FRIEND
COOPER, all of Pownall Road, Dalston, in the County of Middlesex, Electrical
Engineers, do hereby declare the nature of this invention and in what manner the
[Price 811

page_text: same is to be performed, to be particularly described and ascertained in and by the
following statement :—
This invention relates to apparatus for electrolysing chloride solutions, so
constructed and arranged that it can be used in private houses or in establishments
of any kind where there are closets, urinals, sinks drains or the like requiring
disinfecting, such houses or establishments being supplied with a chloride solution
which may be sea water, or, where sea water is not available, it may be a solution
of sodium chloride and magnesium chloride. The electrolysing apparatus according
to this invention consists of a number of sections or elements arranged to act
together, the number of elements being varied to suit the amount of electrolysing
to be effected and the electrical energy available.
As we shall describe referring to the accompanying drawings.
Fig. 1 is a section shewing, by way of example the application of apparatus
according to our invention to the flushing service of a water closet.
Fig. 2 is a vertical section and Fig. 3 is a plan shewing electrolysing apparatus
consisting of seven elements such as may be employed in the arrangement shewn
in Fig. 1.
Figs. 4 and 5 are respectively longitudinal and transverse sections and Fig. 6
a plan of apparatus consisting of a greater number of elements, in this case
seventeen.
In all the figures the same letters of reference are employed as far as possible to
denote like parts.
Each element consists of a tube A of zinc or of metal coated with zinc such as
galvanised iron to form the one electrode and has within it a wire B of platinuin
or other suitable metal to form the other electrode. A number of these elements
are insulated and arranged together in communication by non conducting tubes a
with a common supply pipe C, and discharge into a common recipient D. They
are electrically connected in series the first tube A being connected to the negative
and the last wire B to the positive terminals of a source of electricity, which may
be the supply service for electric lighting. The chloride solution supplied
from a tank E or other source flows by the pipe C up the tubes A, becoming
electrolysed, and the electrolysed liquid passes the discharge D either directly to a
closet, urinal or other place requiring disinfection, or, as shewn in Fig. 1 it may
supply a waste preventer F of ordinary construction. In such case we prefer to
connect the pull and float G to contacts at g, to a valve c and a valve II for the
usual service supply, so arranged that when the float G is up the valves c and H
are closed, no fluid then passing into the preventer F, also the contacts at g are
separated, so that no electricity is supplied to the apparatus. When the pull is
drawn down to cause outflow from the contacts 9 are brought together, the
valves c and H being opened until the float rises again. Such gases as may be
evolved escape by an outlet K.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, we declare that what we
claim is :-
Apparatus for electrolysing chloride solutions employed for disinfecting,
constructed and arranged substantially as described with reference to the
accompanying drawings.
