Improvements in Plates for Secondary Batteries.
I, GIUSEPPE FABBRO, of Morton House, Trott Street, Battersea, in the
County of Surrey, Electrician do hereby declare the nature of this invention to be
as follows:-
My invention relates to the construction of plates or elements for secondary
batteries, and has for its object the formation of a metallic frame, which shall
effectively retain the paste of which the body of such plates is usually formed, and
which frames are adapted also relatively to the cell in such a manner as to prevent
the metallic contact of one plate with another.
My improved plate is provided with an external continuous metallic frame with
an internal groove therein, and a connecting pole piece formed in metallic
continuity thereon.
Within such external frame I provide either vertically or horizontally any
The
convenient number of metallic strips corrugated in a specific manner.
corrugations are veed or inclined to one another, meeting in the centre of the flat
strips and the strips are placed with their wide corrugated surfaces transversely to
the depth of the plate. When the pasty material is packed into the frame it is
retained and locked in position both by the grooved frame and by each half of the
veed corrugated strips, even were the paste to crack.
At the outside of the vertical sides of the frame I provide projecting wings
which are adapted to drop into suitable slots in the non-conducting material of
the cell.
The plates being thus dropped into position, and being held by the wings in the
slots of the cell, are prevented from coming into metallic contact with one another
in the cell.

Improvements in Plates for Secondary Batteries.
I, GIUSEPPE FABBRO, of Morton House, Trott Street, Battersea, in the
County of Surrey, Electrician, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
My invention relates to the construction of plates or elements for secondary
batteries, and bas for its object the formation of a metallic frame, which shall
effectively retain the paste, of which the body of such plates is usually formed, and
which frames are adapted also relatively to the cell in such a manner as to prevent
the metallic contact of one plate with another.
And in order that my invention may be the better understood I now proceed to
describe the same in relation to the drawings hereunto annexed, reference being had

page_text: Figure 1 is a front view of my plate.
Figure 2 is a section thereof."
Figure 3 is an enlarged detail of a corrugated strip; and
Figure 4 shows in plan the plates dropped into a cell.
My improved plate is provided with an external continuous metallic frame A.
with an internal groove A' therein, and a connecting pole piece B, formed in
metallic continuity thereon.
The
Within such external frame I provide, either vertically or horizontally, any
convenient number of metallic strips C. corrugated in a specific manner.
corrugations are "veed" or inclined to one another meeting in the centre of the
widest face of the strips and the strips are placed with their wide corrugated
surfaces transversely to the depth of the plate. When the pasty material is packed
into the frame it is retained and locked in position both by the grooved frame A A'
and by each half of the veed corrugated strips C, even were the paste to crack.
At the outside of the vertical sides of the trame I provide projecting wings D,
which are adapted to drop into suitable slots in the non-conducting material of the
cell E.
The plates being thus dropped into position, and being held by the wings in the
slots of the cell, are prevented from coming into metallic contact with one another
in the .cell.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what 1
claim is:
:-
let. A plate for secondary batteries, characterised by transverse sectional or
horizontal corrugated strips, placed with their wide corrugated surfaces trans-
versely to the depth of the plate, in combination with an internal groove in the
surrounding frame, substantially as and for the purposes described.
2nd. In a plate for secondary batteries, a retaining strip for the body paste,
corrugated substantially as described and illustrated in Figure 3.
Dated this 7th day of April 1896.
