TRUVIDIONAL DIGITIGATION.
An Improved Separator for the Plates of Primary and Secondary
Galvanic Batteries.
1, JOSEPH MOSELEY of the Chapelfield Works Manchester in the County of
Lancaster, India-Rubber Manufacturer, do hereby declare the nature of this inven-
tion to be as follows:-
This Invention relates to Separators for the plates of galvanic batteries and more
particularly for the plates of secondary batteries.
A Separator constructed according to this Invention consists of a comparatively thin
strip of insulating material such as vulcanite, celluloid, or similar substances having a
width equal to or somewhat less than the distance between the plates to be separated,
and having a peculiar form of construction. The shape of the Separator is such as
would be acquired by bending the strip first, at or about the middle of its length so
that the surfaces of the two legs thus produced lie in about parallel planes; and
second, by giving each leg a half twist near the bend so that the two legs are brought
into the same plane.
A Separator constructed according to this Invention is placed astride of a plate so that
the two legs act as Separators in adjacent spaces between the plates.

COMPLETE SPECIFICATION.
An Improved Separator for the Plates of Primary and Secondary
Galvanic Batteries.
I, JOSEPH MOSELEY of the Chapelfield Works Manchester in the County of
Lancaster, India-rubber Manufacturer, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This Invention relates to Separators for the plates of galvanic batteries and more
particularly for the plates of secondary batteries.
A Separator constructed according to these Improvements consists of a comparatively
thin strip of insulating material such as vulcanite, celluloid, or similar substance
having a width equal to or somewhat less than the distance between the plates to be
separated, and having a peculiar form of construction. The shape of the Separator is
such as would be acquired by bending the strip first, at or about the middle of its length
so that the surfaces of the two legs thus produced lie in about parallel planes; and
second, by giving each leg a half twist near the bend so that the two legs are brought
into the same plane.
The Separator is placed astride of each of the plates of the battery or of alternate
plates. If a Separator is used for each plate I prefer to place alternate separators near
opposite ends of the plates so that they form two rows.
I will more particularly describe my Invention with reference to the accompanying
drawings in which Fig. 1 is a side view of a strip of the insulating material from which
the Separator is to be formed; Fig. 2 is a side view of the strip after it has been bent;
Fig. 3 is a side view and a front view respectively, of a Separator after it has had the
final half twist given to each of its legs; Fig. 4 is a longitudinal section of a part of
a battery having the Separators applied to the plates.
The Separators may be moulded to the desired form, but I prefer to construct them
by bending and twisting a strip of vulcanite. In this operation the cut or moulded

page_text: strip Fig. 1 is first bent to the horse shoe form shewn in Fig. 2 by doubling it over a
warm rod and cooling the bent part whilst in the form shewn. I then take a block of
iron having two rectangular parallel holes formed through it in such a manner that
the two limbs of the finished Separator would comfortably fit in the holes. This
block is then warned and the free ends of the bent strip are turned by hand into the
same plane and inserted into and through the holes. The projecting ends of the strip
are then seized by a vice or by pincers, and are drawn through the holes until the bent
portion is nearly in contact with the block. The completely formed Separator is now
withdrawn and cooled without being allowed to become distorted.
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
A Separator for the plates of primary and secondary galvanic batteries, constructed
substantially as hereinbefore described and as illustrated by the accompanying
drawings..
