I, JÉRÔME LOISELET, of 58 bis, Chaussée d'Antin, Paris, in the Republic of
France, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the electrolytical apparatus and more
especially to the construction of the compartments or chambers containing the
liquids to be subjected to the action of the electric current, in such electrolytical
apparatus.
According to my invention in forming the compartments or chambers I employ
a wooden frame preferably rectangular open at its top and sides which latter are
closed in with porous walls of vulcanized fibre and perforated metal sheets the
latter being placed in direct contact with the fibre. The fibre and the perforated
sheets are secured to the aforesaid wooden frame by any suitable means, as for
example by counter sunk-screws, or the said porous walls may be connected by
paste or other suitable adhesive material to the perforated iron-sheets.
The main frame, instead of being made of wood, may be of any other substance
which is a bad conductor of electricity and instead of vulcanized fibre, other
porous material may be used, while the aforesaid perforated metal sheets may be
made of any material which is a good conductor of electricity.
The electrolyte compartment or chamber, constructed as above described, is
combined with a chamber or chambers containing conducting liquids, the per-
forated metal sheets serving as electrodes. Several apparatus of this kind may
be put together and they may be connected either in parallel or in series.
The main advantage of this system is that it prevents the porous walls becoming
warped or creased thus permitting the use of very narrow compartments. Owing
to the reduced thickness of the layer of electrolyte and to the proximity to which
the electrodes may be brought towards each other the amount of electrical energy
necessary for the operation is largely reduced.
The above described apparatus may be applied to all electrolytical operations.

Improvements in Electrolytical Apparatus.

France, Engineer, do hereby declare the nature of this invention and in what
Price 8d.l

in and by the following statement:-
This invention relates to improvements in electrolytical apparatus and more
especially to the construction of the compartments or chambers containing the
liquids to be subjected to the action of the electric current, in such electrolytical
apparatus.
According to my invention in forming the compartments or chambers I employ
a wooden frame preferably rectangular open at its top and sides which latter are
closed in with porous walls of vulcanised fibre and perforated metal sheets the
latter being placed in direct contact with the fibre.
In the annexed drawing:-
Figure 1 is an external side elevation. Figure 2 is a transverse section on the
line cd (Fig. 1) and Figure 3 is a horizontal section on the line ab (Fig. 1) of a
compartment according to my invention.
In these three figures A represents the wooden frame, B the plate of vulcanized
fibre and C, the perforated metal-sheets.
The fibre B and the perforated sheets C, are secured to the aforesaid wooden
frame A by any suitable means, as for example by counter sunk-screws a¹ or the
said porous walls B may be connected by paste or other suitable adhesive material
to the perforated iron-sheets C.
The main frame, instead of being made of wood, may be of any other substance
which is a bad conductor of electricity and instead of vulcanized fibre, other porous
material may be used; while the aforesaid perforated metal sheets may be made
of any material which is a good conductor of electricity.
The electrolyte compartment or chamber, constructed as above described, is
combined with a chamber or chambers containing conducting liquids, the per-
forated metal sheets serving as electrodes. Several apparatus of this kind may
be put together and they may be connected either in parallel or in series..
The main advantage of this system is that it prevents the porous walls becoming
warped or creased thus permitting the use of very narrow compartments. Owing
to the reduced thickness of the layer of electrolyte and to the proximity to which
the electrodes may be brought towards each other, the amount of electrical energy
necessary for the operation is largely reduced.
The above described apparatus inay be applied to all electrolytical operations.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I claim
is:-
1. In electrolytical apparatus compartments or chambers comprising a frame of
wood or other non-conducting material and walls of porous material and perforated
sheets of metal or other conducting substance in contact with the said porous
material substantially as described.
2. The improved compartments or chambers for electrolytic apparatus sub-
stantially as herein before described and shewn in the accompanying drawings.
