411,623. Accumulators. JOEL, H. F., 10, Squirrels Heath Avenue, Gidea
Park, Essex. March 15, 1933, No. 7894. [Class 53.] A cylindrical
negative electrode N surrounds a positive electrode consisting of a
number of plates C of decreasing width as shown in plan in Fig. 5. The
outer electrode may be of notched shape as shown and the centre plates
of the positive electrode may be inclined as shown in Fig. 4 to assist
circulation of the electrolyte. The plates are joined at the top and
bottom by rings B. The cell is closed by a double lid D having a
projection R for indicating the correct position of the cell in an
outer casing carrying a lamp.

PROVISIONAL SPECIFICATION.
Improvements in Electric Storage Batteries or Accumulators.
I, Ha ENRY FRANCIS JOEL, 10, Squirrels Heath Avenue, Gidea Park,
Essex, a British subject, do hereby declare the nature of this
invention to be as follows:This invention of improvements in electric
storage batteries has reference to the construction of the electrodes
and has for its object -the more efficient action and increase in the
output in proportion to the weight of the battery.
In one example of a cylindrical type of accumulator cell such as at
present used in portable electric lamps f Qr mi er, -the usual
practice is to make the central positive element of a single cast lead
of cylindrical form with apertures for retaining the active material,
an oxide of lead, with a negative of a tubular form surrounding the
positive, and alo'o having apertures for holding the active material.
In my present invention:-I make a cylindrical type of battery with the
inside and positive electrode made up with a series of flat plate
electrodes, say six in 2 f number, cast with apertures on their
surfaces, for holding the active material.
The two central plates are made of a width and height to go into the
centre of the outer cylindrical negative without touching or making a
connection with the inside of the negative electrode and with a
channel, or clear space open at the top and bottom between the two
central plates, and further two other plates, one on each side outside
the two central plates, with a reduced width and leaving a clear space
lbetween them and the outer cylindrical negative, and a further two
plates of still lesser, width are placed on the outsides, -40 and
I-join these six central plates together at the top and bottom, and
with a terminal at the top.
The positives and negative electrodes are placed in positign in a
cylindrical lbattery case, with terminals for connections on the top
cover.
Further, and 'alternatively to making the negative of a plain tubular
form-I make the outside cylindrical negative with the inner surface
crenellated or indented, to correspond with and allow room for partial
entrance at regular intervals of the side edges of the multiple
positive plates inside The outside vertical edges of the positive
plates
fitting
into and without touching the surface of the
indentations in the negative electrode.
By this' constriction, with open spaces between the plates:-I obtain
an-increaied
surface
for
the
action and circulation of the
electrolyte, and a free outlet Yor the escape of the gases when
charging the accumulator, and also when discharging.
To assist the circulation of the electrolyte in the cell I arrange the
two central plates with their sides inclined to each other with a
decreased or tapering space between them at the top, and a little
wider space ibetweeu them at the bottom so that -the gases generated
in charging rise in the central space and cause increased circulation
of the electrolyte To assist this still further I enclose the two
sides of -the central plates to form what may be termed a duct, or
funnel.
The central positive plate electrodes are all joined together by a
circular ring or alternatively by a flat strip or bar of lead at the
top, and also at the bottom, for strengthening the combination, with a
terminal mounted on the top of the cell on the flat strip or bar ' The
negative also has a corresponding terminal on the outside and top of
the cell-.
To
increase
the
active surface of the negative and outside
electrode-In addition to making the inside surface crenellated as
before described, I provide, or leave free spaces, or holes, at
regular intervals in the framework, or casting, with perforated lead
covering of the negative electrode through which the electrolyte can
circulate.

Improvements in Electric Storage Batteries or Accumulators.
I, HENRY FRANCIS Jon L, 10, Squirrels British subject, do hereby
declare the Heath Avenue, Gidea Park, Essex, a nature of this
invention and in what lPrice 1/-l 2 411,623 manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement:This invention relates to improvements in the construction of Electric
Storage batteries or Accumulators, more especially o I the cylindrical
type applicable for use with portable electric lamps.
In the
parts:
accompanying
drawings like letters indicate like, or similar
Fig 1, is 1 a sectional elevation of a cylindrical type of my battery
showing the cluster of divided Mat plate'type of positive electrode
with a cylindrical type of negative electrode on the outside.
h Fig 2, is a sectional plan of Fig 1, showing the position of the
-cluster or group of divided positive plates, inside the outer
cylindrical negative.
-Fig -3, is a plan of the top of the cell Fig 1.
Fig 4, is a sectional elevation of an alternative arrangement of the
positive plates to induce circulation of the -electrolyte.
Fig 5, is 'a sectional plan of -Fig 4, showing -the construction -and
arrangement of -the -positive electrodes and of a crenalated -shape of
-negative with increased surfaces for action, and -disposition -of the
inner surface-in respect to the position and additional width of the
positive plates allowed by the recesses inl the crenulated surface of
the negative.
In
one embodiment of my invent-ion -and in reference to the
'drawings:-I make a cylindrical form of -acciu Mulator cell of
celluloid' 6 r other suit&ble material, such as ebonite, shown at Fig
1, a sectional elevation, Fig 2, a sectional plan, and Fig -'3, a plad
bf the top '6 f the 'cell 'With -a double deck:detachable lid -D, and
terminals T, T, with a register -R,, {for placing the cell in correct
position for making the biufer -spring contacts With an outside lamp
case, adapted' for' conection with a lamp.
The two cdntral positive plate electrodes 0 O are -made -with lead
frames and -apertures for holding the -active inaterial, such-as an
oxide of lead,-'of a-width and height to go into the ccentre of -the
inside of the cylindrical negative electrode X, with 'bchanniels' -or
chear -"sp S'c-s bet&d A the plates, open at'the':top ind-bbttom, and
further two oother tplates', e on-'oh each side outside the two
ceitral 'pla-tes with a reduced width 'and leaving a clear space
between them and the outer cylindrical negative N, and further two
plates 0, 0, of still lesser width are placed on the ' outside, and
these six plates are joined together at their outer edges, top and
bo-tt'in, with two circular ringss of lead B, -'B, with a positive
terininal-T, on the top -ring B as shown on the drawingsat Figs 1, 2
and 3 T' is the negative terminal.
At Figs 4 and 5, I show an alternative arrangement of the six positive
plates 70 and to assist the circulation of the electrolyte in the
cell, I arrange the two central plates C, 0, with their sides inclined
to each other to make a decreased and tapering space between the
plates at 75 the-top, and a-little wider space between them at -the
bottom, and by enclosing the -sides form a duct -V, shown at Fig 4,-so
-that the gases generated in charging the cell rise -in the central
space, and by 80 accumulation -at the top opening V, tend to circulate
the electrolyte.
At Fig 5,-I show the negative N 'with a crennlated surface with
perforated lead sheathing on both inside and outside the 85 frame of
ribs RI to increase the active surfaces on both inside and outside to
correspond with the increased surface obtained by the new divided
construction of te positive plates: g In addition to or alternatively
with making the inside surfaces crenclatd as just described, I provide
or leave spaces or holes at regular intervals in the -pet.
forated lead sheathing-, as shown at-A, A, 95 Figs 1, and 2 for access
of the electrolyte.
Having now particularly-described and ascertained-the nature of my
said invention and in-what manner the -same is -to j O g
