PROVISIONAL SPECIFICATION.
Improvements in Secondary Batteries.
I FRANK KING of 38 Chesilton Road, Fulham in the County of Middlesex, Electrical
Engineer do hereby declare the nature of this Invention to be as follows:-
My Invention consists of improved means for supporting the plates of secondary
batteries whereby increased facility for removing the plates of one denomination
from their position in relation to the plates of the opposite denomination is obtained
and clearer spaces are provided between the plates for inspection and removal of
accidental contacts.
In carrying out my Invention I connect the whole of the plates of one denomina-
tion together, by means of the ordinary connecting bar at the top of the battery,
and on the bottom corners of the said plates I make prolongations forming feet for
raising the plates above the bottom of the containing cell as described in the Specifi-
cation to my former Letters Patent dated the 10th December 1887 No. 17047 the said
feet being metallically connected together by burning or casting thereto a metal strip
which embraces the bottom edge of the whole of the feet of these plates.
To the sides of these plates in any convenient position but preferably at the top and
bottom corners of both sides or edges thereof, I attach by casting burning or the
like, brackets or hooks or morticed or slotted extensions or projections in which I
place bars of insulating material, long enough to extend along the edges of the whole
set of plates. These bars are provided with notches which engage the hooks or slots
in the projections or brackets on the plates for the purpose of ensuring equality of
distance between the said plates.
In the upper edges of the bars of insulating material other notches are provided
midway between those previously referred to for the reception of teeth or such like
projections provided on the edges of the plates of the opposite denomination to those
which carry the insulating bar for the purpose of carrying or supporting the said
plates, the teeth or projections being attached to or formed on the plates at any suitable
part, but preferably at the top and bottom corners of each of the side edges by casting
burning or otherwise, or instead of the notched insulating bars herein before described
plain rods may be employed on which are slipped ferrules or saddles of insulating
material provided with notches for supporting the plates.
The teeth or projections are arranged in such positions as to enable one of the in-
sulating bars on each side of the plates so provided to carry the weight of the plates,
the other bars or the ferrules or saddles carried thereon merely serving to prevent
the plates from swinging or falling into contact with the plates of the opposite
denomination.

Improvements in Secondary Batteries.
1 FRANK KING of 38 Chesilton Road Fulham in the County of Middlesex 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 :-
My Invention consists of improved means for supporting the plates of secondary
batteries whereby increased facility for removing the plates of one denomination from

page_text: their position in relation to the plates of the opposite denomination is obtained and
clearer spaces are provided between the plates for inspection and removal of
accidental contacts.
I will describe my Invention with reference to the accompanying drawings I
connect the whole of the plates of each denomination together at the top of the
battery which may be effected by means of the ordinary connecting bars and on the
bottom corners of the plates of one denomination for example the negative pole
plates AI provide preferably by burning or casting thereon, prolongations B forming
feet for supporting the said plates above the bottom of the containing cell Cas described
in the Specification of Letters Patent No. 17047 granted to me and dated the
10th December 1887 and metallically connect together the whole of the feet on each
side of this series of plates by attaching to the bottom edge of the feet (preferably by
burning or casting) metal bars or strips D as shewn in Figures 1 and 4.
To the sides of these plates A in any convenient position but preferably at or near
the top and bottom corners of hoth sides or edges thereof as shewn, I provide by
casting burning or the like brackets or hooks or morticed or slotted extensions or
projections E, to support bars F of insulating material and of sufficient length to
extend along the edges of the whole set of negative and positive plates. Each of the
bars F is provided on one of its vertical sides with notches G as shewn in Figures 14
and 1 which engage the hooks or projections e on the brackets E of the plate A
Figure 1. for the purpose of ensuring equality of distance between the said plates.
In the upper edges of the bars F of insulating material and midway between the
notches G other notches H are provided for the reception of lugs or projections I
provided on the edges of the positive pole plates K (or the plates of the opposite
denomination to those which carry the insulating bars F) for the purpose of carrying
or supporting the said plates as shewn in Figure 1. The bars F are placed in the
recesses in the projections E from above the hooks or projections e entering the slots G
in the bars from below.
Figure 2 illustrates a modification in which horizontal recesses are made in the
projections E and the bars F of insulating material are provided with notches on
their top surfaces only, for the reception of the lugs formed on the pole plates of
both denominations the lugs e which constitute the tops of the recesses in the plates A
entering each alternate notch G in the bars F and the lugs I on the plates K entering
the notches H between the notches G. I prefer to make the bottoms of the notches G
in the bars F to incline or slope outwards as shewn in Figure 24 the lugs or pro-
jections forming the tops of the recesses in the plates A being made to corre-
spondingly incline so as to nip the bar between the said projections and the lower
surfaces of the recesses and thereby securely retain the bars F in position.
Instead of the notched insulating bars hereinbefore described plain rectangular rods
or bars of insulating material as shown in Figures 3 and 4 or round rods E
Figure 4 may be employed, the said rods or bars being passed through openings
formed in the extensions E of the pole plates A of one denomination the said
plates being maintained at the required distance apart by saddles L. Figures 3 and 4
or by ferrules I Figure 4 of insulating material placed on the bars i and provided
with notches H for the reception of the lugs or projections I formed on the pole
plates K of one denomination.
The teeth or projections on the plates K may be so arranged that only one of the
insulating bars F on each side of the plates carry the weight of the whole of the
plates K the other bars or the ferrules or the saddles carried thereon merely
serving to prevent the pole plates of one denomination from swinging or falling into
contact with the pole plates of the opposite denomination.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
First. In secondary batteries connecting the pole plates of one denomination by

page_text: means of bars F of insulating material in combination with feet or downward pro-
jections connected by bars D substantially as and for the purpose hereinbefore
described with reference to the accompanying drawings.
Second. In secondary batteries connecting the pole plates of one denomination by
means of bars of insulating material in combination with feet or downward projections
connected by bars D₁, and notched projections E engaging notches or recesses G in
the bars F, the pole plates of the opposite denomination having lugs or projections [
engaging notches or recesses H in the bars F midway between the notches G
substantially as and for the purpose hereinbefore described with reference to the
accompanying drawings.
Third. In secondary batteries, the pole plates of one denomination having down-
ward projections or supporting feet in combination with projections on the edges
of the plates through which bars F of insulating material are passed, and on which
bars distance pieces L of insulating material are placed the said distance pieces having
notches or recesses for the reception of lugs or projections provided on the pole plates
of the opposite denomination substantially as and for the purpose hereinbefore
described with reference to Figures 3 and 4 and Figure 44 of the accompanying
drawings.
Fourth. The general constructions and combinations of parts constituting
improvements in secondary batteries substantially as herein before respectively described
and illustrated in Figures 1. 1ª and 1, Figure 2 Figures 3 and 4 and Figure 4ª of
the accompanying Drawing.
