Improvements in Insulating Frames for Electrodes.
I, MORIEZ ENGL, of 1, Bellariastrasse 4, Vienna, in the Empire of Austria,
Undertaker for Buildings, do hereby declare the nature of this invention to be
as follows:
This invention has for its object a device or arrangement for electrodes to place
the same in the cells in such a manner that they are insulated from each other
to prevent shunts, but that they may extend or dilate to all sides and that the
electrolyt has uniform admittance to all surfaces of the electrodes.
For the insulated arrangement of the electrodes in the cells hitherto (heretofore)
one has employed supporting discs consisting of plates provided with ribs and
grooves which were leaned onto the walls of the cell and were adapted to be
removed.
These supporting discs have the inconvenience that they do not permit a lateral
extension or dilation of the electrodes and do not permit the admittance (entrance)
of the electrolyt.
This invention has for its object to provide such a device for the insulation of
the electrodes that the electrodes may dilate (extend) to all sides, nevertheless they
receive a perfect insulation and each displacing is prevented.
This improved device consists in generally of a grate-like insulating frame, to
be placed into the cell, in the interstices or slots of which (limited by rods) the
electrodes are inserted, and where between each two of such electrodes a perforated
plate of insulating material is inserted, which prevents all shunts.
The insulating frame consists of a number of rods of annular section and of
insulating material, which rods are arranged parallel to each other and in distances
corresponding with the thickness of the electrodes, and which are connected at the
top and below by rods or strips. Two such grates are somewhat inclined to each
other and form an insulating frame.
This connection is made by strips or rods of insulating material, and I may
eventually also provide stiffening rods for the stability of the frame. I may
also provide handles to facilitate the transport and the easy removing and inser-
tion of the frames provided with electrodes into or from the cells filled with acid.
The insertion of the electrodes into the insulating frame is effected by inserting
the electrodes into the opposite interstices of both grates, and near each electrode,
on one side or on both sides I employ a perforated thin plate of insulating material,
which is put loosely beside or close to the accumulator-plate or may be attached
to the rods.
Hereby is attained that even when the mass should happen to crumble off from
an electrode, a shunt cannot take place as the piece crumbled off of the one

page_text: electrode is kept off from the neighbouring (opposite) electrode by the insulating
plate.
By the inclination of the two grates towards each other the rods prevent warping
of the casting of the insulating plates as well as of the electrodes during the
loading and disloading operation, as no large surfaces project over the rods.
Instead of constructing the grates of rods and cross rods, the same may also
be made of plates which are provided with slots corresponding to the thickness
of the electrodes.
Two such plates are connected in a similar manner as the rod-grates by cross
rods or traverses and by stiffening rods.
As material for the frame I may employ each sort of non-conducting material.
Frames of the described construction have the advantage that they maintain
the electrodes constantly insulated so that no shunt is possible; besides that the
electrodes may dilate (extend) freely, and finally that the frame as well as the
plates may be removed from the cell and may be inserted again, in case as a plate
should happen to be interchanged for repairing.

I, MORIEZ ENGL, of 1, Bellariastrasse 4, Vienna, in the Empire of Austria,
Undertaker for Buildings, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention has for its object a device or arrangement for electrodes to place
the same in the cells in such a manner that they are insulated from each other,
but that they may extend or dilate to all sides and that the electrolyte has
uniform admittance to all surfaces of the electrodes.
For the insulated arrangement of the electrodes in the cells hitherto (heretofore)
one has employed supporting discs consisting of plates provided with ribs and
grooves which lead into the walls of the cell and are adapted to be removed.
These supporting discs have the inconvenience that they do not permit a lateral
extension or dilatation of the electrodes and do not permit the admittance (entrance)
of the electrolyte.
This invention has for its object to provide such a device for the insulation of
the electrodes that the electrodes may dilate (extend) to all sides, nevertheless they
receive a perfect insulation.
This improved device consists in general of a grate-like insulating frame, to
be placed into the cell, in the interstices or slots of which the electrodes are placed,
and between each two of such electrodes a perforated plate of insulating material
is inserted.
In the accompanying drawing,
Fig. 1, is a view, partly broken of such an insulating frame, formed of rods
of annular section.
Fig. 2, is the side view, also partly broken.

Fig. 4, is a horizontal section of a modification with flat rods, and of which.
Fig. 1, is also the elevation.
Fig. 5, represents in elevation and
Fig. 6, in plan view a third modification formed of two plates provided with
suitable openings (slots).
The insulating frame Figs. 1,--3", consists of a number of rods a, a, of annular
section and of insulating material, which rods are arranged parallel to each other
and in distances corresponding with the thickness of the electrodes, and which
Two such grates
are connected at the top and below by rods C C and strips c, c.
are somewhat inclined to each other to form an insulating frame.
We
The connection is made by strips or rods d, d, of insulating material, and we
may also provide stiffening rods f, f, and g, g, for the stability of the frame.
may also provide handles h, h, to facilitate the transport and the easy removing
and insertion of the frames provided with electrodes into or from the cells filled
with acid.
The insertion of the electrodes into the insulating frame is effected by inserting
the electrodes into the opposite interstices of both grates, and near each electrode,
on one side or on both sides we employ a perforated thin plate k of insulating
material, which is put loosely beside or close to the accumulator plate or may be
attached to the rods a, a, (see Fig. 1, in dotted lines).
Hereby is attained that even when the mass should happen to crumble off from
an electrode, an escape cannot take place, as the piece crumbled off of the one
electrode is kept off from the neighbouring (opposite) electrode by the insulating
plate k.
By the inclination of the two grates towards each other the rods a, a, prevent the
(warping) of the insulating plates as well as of the electrodes during the loading
and disloading operation, as no large surfaces project over the rods.
In Fig. 4, is illustrated a plan view of a similar insulating frame, in which
however no similar rods as in Fig. 1 to 3, but flat rods are employed for forming
the grate, which rods are united in analogous manner to grates and these latter
to frames.
Instead of constructing the grates of rods and cross rods, the same may also
be made of plates n, n, (Figs. 5, and 6,) which are provided with slots p, p,
corresponding to the thickness of the electrodes.
Two such plates n, n, are connected in a similar manner as the rod-grates by
cross-rods or traverses and by stiffening rods.
As material for the frame I may employ any non-conducting material.
Frames of the described construction have the advantage that they maintain
the electrodes constantly insulated so that no escape is possible; besides that the
electrodes may dilate (extend) freely and finally that the frame as well as the
plates may be removed from the cell and may be inserted again, in case a plate
should happen to be interchanged for repairing.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. An insulating frame for electrodes, characterized by two grates, being
inclined towards each other and connected by transverse bars and stiffening bars
to a frame, which frame is put or inserted in the cell, and in the grooves (formed
by the rods or by cutting out the plates) of which the electrodes can be inserted,
so that the latter may dilate freely and where the electrolyte has uniform entrance
or admittance to all surfaces of the electrodes.
2. In an insulating frame, described in claim 1, the arrangement of perforated
plates k, k, insulating material near the electrodes and the rods, substantially as
herein described and according to the accompanying drawing.

page_text: 3. In insulating frames for electrodes, the combination of the various parts
substantially as above described in this specification for the purpose specified.
