improvements in Secondary Electric Batteries or Accumulators.
I, EDWARD JAMES CLARK, of Crispin's Wharf, Marshgate Lane, Stratford, in the
County of Essex, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to certain improvements in secondary electric batteries or
accumulators, and has for its object the provision of good insulation between the
plates or electrodes, with ample space for electrolytic action, and also a method
of and means for supporting said plates or electrodes.
In order that my invention may be clearly described, I have appended the
accompanying sheet of drawings, in which Figure 1 is an end elevation of a
negative plate in situ showing the means for supporting the positive plate,
indicated by the dotted outline. Figure 2 is a sectional elevation of three plates
on the line A B Figure 1. Figure 3 is a detached view of the insulator or separator.
Similar letters of reference are used to indicate corresponding parts throughout
the several views.
In carrying my invention into effect I use a plate or electrode C of any grid
formation, with a lug E for connection, and a hook a¹ cast or formed upon it. Two.
foot lugs
upon the negative plate shown by the elevation Figure 1, support the
plate C upon the floor of the cell. The positive plate C¹ has no foot lugs, but is
supported by the hooks a a¹ engaging with rods d d placed upon each side, and
resting upon the negative plates. Thus the thicker positive plates or electrodes are
allowed sufficient room for longitudinal and lateral expansion. Between each pair of
plates, a pair of insulators or separators b are interposed, these being hooked or curved
at the top to engage with the insulating rods d d¹. The latter are made of any
suitable insulating material and the insulator b of glass, preferably, and are suspended
from the rods d d¹ and kept from swaying laterally by the insulating rods c which are
held in position by hooks or clutches cast upon the bottom of the negative electrodes C,
and which are pinched or pressed into the closing position as shown by Figures 1
and 2, the insulator or separator being shown detached by Figure 3.

My invention relates to certain improvements in secondary electric batteries or
accumulators, and has for its object the provision of good insulation between the
plates or electrodes, with ample space for electrolytic action, and also a method of
and means for supporting said plates or electrodes.
In order that my invention may be clearly described, I have appended to my
Provisional Specification the accompanying sheet of drawings in which Figure 1 is an
end elevation of a negative plate in situ showing the means for supporting the
positive plate, indicated by the dotted outline. Figure 2 is a sectional elevation of
three plates on the line A B Figure 1. Figure 3 is a detached view of the insulator
or separator. Similar letters of reference are used to indicate corresponding parts
throughout the several views.
In carrying my invention into effect I use a plate or electrode C of any grid
formation with a lug E for connection and a hook a cast or formed upon it to hold in
place the rods a. Two foot lugs D shown by the elevation Figure. 1, support the
plate C upon the floor of the cell. The positive plate C¹ with a connecting lug El has
no foot lugs, but is supported by the hooks a¹ engaging with rods d d placed upon
each side, and resting upon the negative plates C. Thus the thicker positive plates or
electrodes C¹ are allowed sufficient room for longitudinal and lateral expansion.
Between each pair of plates, a pair of insulatore or separators b are interposed, these
being hooked or curved at the top to engage with the insulating rods d d¹. The
latter are made of any suitable insulating material, and the insulators b of glass,
preferably, and are suspended from the rods d d', and kept from swaying laterally by
the insulating rods c which are held in position by hooks or clutches cast upon the
bottom of the negative electrodes C, and which are pinched or pressed into the closing
position as shown by Figures 1 and 2, the insulator or separator being shown detached
by Figure 3.
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 electric batteries or accumulators the method of and means for
building up and supporting the electrodes or plates upon insulated rods, with hooked
separators and guide bars also insulated, substantially as and for the purposes herein
set forth and shown by the appended drawings.
Second. In secondary electric batteries or accumulators the use of hooked
separators of insulating material depending from an insulated rod and held in position
by other insulated rods substantially as herein described and shown by the appended
drawings.
Third. In secondary electric batteries or accumulators the construction of electrodes
or plates with hooked extensions for suspension at the top, and hooked extensions
upon the lower edge, for carrying insulated separator guides substantially as herein
described and shown by the appended drawings.
