PROVISIONAL SPECIFICATION
Improvements in or connected with Secondary or Electric Storage
Batteries.
I FRANK KING of 4 Great Winchester Street in the City of London Engineer
do hereby declare the nature of this invention to be as follows
-
My invention relates to secondary or electric storage batteries and has for its
object to provide a more perfect arrangement of battery and especially to provide
means whereby the plates or elements of one denomination are supported relatively
to the plates or elements of the other denomination in such manner that active
material which may fall from the plates or elements will be effectually prevented
from causing short circuiting between the plates or elements. According to my
invention the plates or elements of one denomination are supported by resting in
or upon saddle or supporting pieces which maintain the lower edges of said plates
at a sufficient distance above the bottom of the containing cell or vessel the said
saddle or supporting pieces being so formed as to divert any falling activo material
in such manner as to prevent it from making connection between the plates of
opposite denomination. The said saddle or supporting pieces are made of ebonite
or other acid resisting and insulating material and preferably with a groove or
ccess at their underside which receives a rib o projection atanding up from the
connecting bar (or bars) joining at the bottom the plates or elements of opposite
denomination to those which the saddle is intended to carry or support In the
upper side of the said saddle or supporting pieces is another groove for receiving
the lower edge of the plates or elements to be supported the said saddle or
supporting pieces being formed with inclined surfaces, and projecting so far
outwards on all sides from the metallic parts on which they are supported as to
divert any active material which may fall from the plates and cause it to deposit
in the bottom of the cell or vessel. The plates on elements are preferably made
with pins or projections from the inner sides of the openings therein the said pins
or projections being preferably arranged so that they form a claw-like arrangement
projecting inwards and outwards alternately on opposite sides the said pins or
projections being preferably arranged in each opening so that they form a star or
cross-like figure projecting from the inner sides of the openings on each side of the
plate the arms of the star or closs on one side alternating with the arms of the star
o cross on the other side. The plates or elements are preferably maintained in
proper position by means of insulating strips so shaped as to seat on projecting ribs
on the one plate and bear upon the opposite plate.

Batteries.
I, FRANK KING of 4 Great Winchester Street in the City of London, Eugineer,
do hereby declare the nature of my 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 secondary or electic storage batteries and has for its
object to provide a more perfect arrangement of battery and especially to provide
means whereby the plates or elements of one denomination are supported relatively
to the plates or elements of the other denomination in such manner that active
material which may fall from the plates or elements will be effectually prevented
from causing short circuiting between the plates or elements.
And in order that my invention may be clearly understood I will refer to tho
accompanying diawings in which Figure 1 sliens in elevation Figure 2 in cross
section and Figure 3 in horizontal section » portion of a storage or secondary
battery constructed according to this invention. A is a vessel or cell containing
positive plates B and negative plates C each series of plates being connected to a
conductor in the ordinary manner, the plates or elements 13 of one denomination
are supported by resting in or upon saddle or supporting pieces D which maintain
the lower edges of said plates at a sufficient distance above the bottom of the
containing cell or vessel the said saddle or supporting pieces being so formed as to
divert any falling active material in such manner as to prevent it from making
connection between the plates of opposite denominations. The said saddle or
Bupporting pièces D are made of ebonite or other acid resisting and insulating
material and preferably with a groove or recess at their underside which receives
a rib or projection e standing up from the connecting bars E joining at the
bottom by projections therefrom E the plates or clements of opposite denomi-
nation C to those which the saddle is intended to carry or support. In the upper
side of the said saddles or supporting pieces is another groove for receiving the
lower edge of the plates or elements B to be supported the said saddle or supporting
pièces being formed with inclined surfaces and projecting so far outwards on
all sides from the metallic parts on which they are supported as to divert any
active material which may fall from the plates and cause it to deposit in the bottom
of the cell or vessel A The plates on elements' B and C are preferably made with
pins or projections b and c from the inner sides of the openings therein the said pins
or projections being preferably arranged so that they form a claw-like arrangement
projecting inwards and outwards alternately on opposite sides the said pins or
projections being preferably arranged m'each opening so that they form a star or
cross-like figure projecting from the inner sides of the openings on each side of the
plate the arms of the stai or cross on one side alternating with the aims of the
star or cross on the other side. The plates or elements B and C are preferably
maintained in proper position by means of insulating strips F so shaped as to seat
on projecting ribs G on the one plate and bear upon the opposite plate.
Having now particularly described and ascertained the nature of my invention
and what manner the same 1s to be performed I declare that what I
claim is:
1. In a secondary or electric storage battery insulating supporting saddles for the
plates of one denomination the said saddles being supported on 1bs or projections
forming nart of the connecting her or hare of the plates of the other denomination

page_text: 2. In a secondary or electric storage battery the combination of ribs or
projections G on the plates of one denomination with insulating distance pieces F
and insulating supporting saddle pieces D for the plates of the other denomination
carried ou or by the metallic pillars forming part of the connecting bar or bars of
the plates of first named denomination substantially as hereinbefore described and
illustrated in the accompanying drawings.
