Improvements in Electric Batteries.
We, THE ELECTRICAL POWER STORAGE COMPANY Limited of 4 Great Winchester
Street in the City of London and HERBERT WILLIAM BUTLER of 8 Wynne Road,
Brixton in the County of Surrey, Electrical Engineer do hereby declare the nature
of this Invention to be as follows:-
This Invention has for its object to provide means whereby the elements or plates
of primary or secondary batteries are maintained at the proper distance apart and
injurious contact is prevented whilst allowing proper circulation of the electrolyte.
According to this Invention there is situated between every two adjacent plates or
elements a perforated separator of vulcanite porcelain prepared cardboard or other
like or suitable material having formed on or secured to or passed through it,
projections which extend outwards from the side or sides of the separator.
Or the separators may be mounted in frames on or in which the projections
aforesaid are formed or placed.
In all cases the projections constitute distance pieces between the plates and the
separators.

Brixton in the County of Surrey Electrical Engineer 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 :-
This Invention has for its object to provide means whereby the elements or plates
of primary or secondary batterics are maintained at the proper distance apart and
injurious contact is prevented whilst allowing proper circulation of the electriolyte.
According to this Invention there is situated between every two adjacent plates or
elements a perforated or reticulated separator of celluloid, vulcanite porcelain,
prepared cardboard or other like or suitable insulating and acid proof material having
formed on, or secured to, or passed through it, projections or distance pieces which
extend outwards from the side or sides of the separator.
Or the separators may be mounted in frames on or in which the projections
aforesaid are formed or placed.
In all cases the projections constitute distance pieces between the plates and the
separators.
The accompanying drawings illustrate arrangements according to this Invention.
Figure 1 represents in transverse section the separator in position between two
plates c of a battery. A is the perforated sheet constituting the separator and B
are the distance pieces each consisting of a pin passing through the separator A and
having a nut rivetted screwed or otherwise fixed on each end or there may be a fixed
head on one end and a nut screwed or fixed on the other end. Figure 2 represents
a side view of this separator.
Figure 3 represents in transverse section a modification in which two pieces of
perforated material are used to make the separator with small distance pieces between
them.
As in the former case B are the distance pieces, two plates of the battery and
Figure 4 is a side view.
Figure 5 represents a separator in which the distance pieces are made in the form
of ribs B secured to the separator by being joined at the ends or rivetted through.
As in the former cases C. are two plates of the battery and Figure 6 is a side view.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed we declare that what we claim is.
In and for electric batteries a perforated or reticulated separator and distance
pieces or projections substantially as and for the purposes hereinbefore described.
