CHARLES EDWARD BUELL of New Haven in the State of Connecticut United
States of America. IMPROVEMENTS IN SECONDARY BATTERIES OR STORAGE
BATTERIES, AND IN THE METHODS OF, AND MEANS FOR CHARGING AND DIS-
CHARGING THE SAME."
This Invention relates to that class of storage or secondary batteries in which
the electric current produces a change or decomposition of the materials as the
electric current passes into such battery.
The object of the invention is to obtain a large amount of surface and, a uniform
action of the electrolytic solution upon the same.
My Invention relates to an improved secondary battery and it consists of a
battery having one or both of its electrodes formed of globular or spherical pieces.
of lead, carbon or other suitable material, such form of the pieces enabling the
largest amount of surface of a given bulk of material confined within a given space
to be exposed to the action of the exciting fluid or electrolyte employed.
It further consists in constructing the battery of an outer cell of lead or lead
lined material and an inner cell of porous material placed within the outer cell,
both cells being filled with the globular or spherical pieces of lead, carbon or other
suitable material and a suitable exciting fluid or electrolyte, such as salt and water
or sulphuric acid and water or other fluid and terminals of the battery consisting
preferably of binding posts connected to the outer cell or to the lining or contents
thereof and to the contents of the inner cell preferably through a plate or wire of
lead, carbon, or other suitable material
This form of battery is very easily and cheaply constructed. The spherical
pieces constituting the electrodes present to each other mere points of contact and
LD027

page_text: afford a large surface exposed to the action of the liquid and produce a battery of
lower internal resistance and of greater capacity than electrodes of like material of
the same weight but composed of other forms of pieces occupying the same space.
Furthermore the electrode can be formed of common lead shot of a given number
or grade any person can readily produce a standard battery, the quantity and grade
of the shot and the size of the cells being given.
Batteries made in accordance with my invention can be charged either by
currents developed by galvanic batteries or by dynamo electric machines or other
electric generators and they may be charged singly and discharged singly or
charged singly and discharged in series or charged coupled for quantity and
discharged coupled for intensity or charged coupled for quantity in multiple
series and discharged coupled for tension or otherwise.
Two series may be arranged to be alternately charged from the same charging
circuit and to be discharged into a common working circuit or one or more of the
batteries of a series may be charged while the others are discharging.
Heretofore when secondary batteries have been charged by dynamo electric
machines it has been the practice to first speed up the machine on an open circuit
and then close the circuit through the secondary batteries. Before the circuit
is closed the armature of the machine merely gains momentum and but little
electrical power is developed, but upon the closing of the circuit the machine
develops power very rapidly.
After a secondary battery has been once used it remains thereafter partially
charged and therefore when after first use the circuit of a dynamo electric machine
is closed through it, it instantaneously reacts before the machine develops sufficient
power to overcome it and thus operates to change the polarity of the magnets of
the machine and renders the charging operation a failure.
To obviate the evils arising from this old mode of charging I combine with the
dynamo electric machine a developing circuit in which the machine is worked
temporarily a main charging circuit including the secondary battery or batteries
to be charged and means for dividing the current through the developing circuit
and the main charging circuit and then breaking the developing circuit without
breaking the main charging circuit.
I arrange these secondary batteries in connection with a magueto or dynamo
electric machine and its circuits; so that the current will be supplied to one or more
of such batteries in series or multiple circuit connections and take off the current
_either from the single cells or by circuit connections arranged either for quantity
or intensity of current, and I provide a revolving circuit closing device propelled
by clockwork or otherwise and arranged to connect a portion of the storage
battery cells with the dynamo generator and another portion with electric lamps
or other working devices, and to transpose these connections periodically.
In cases where the dynamo generator is actuated by a varying source of power
such as a windmill. I combine a governer and circuit connections in such a manner
that when the speed is lessened below the minimum standard so that there is risk
of the storage batteries reacting upon the dynamo generator, said governer breaks
the circuit connections to said storage batteries, and establishes a new external
circuit independent of the storage batteries. Sometimes I employ a polarized
magnet in the circuit between the dynamo and the storage batteries, the tongue
or armature of the said polarized magnet acting as a switch to change the circuit
connections as aforesaid
Instead of hand switches an automatic switching device operated by the dynamo
electric machine may be employed
I sometimes employ an arrangement in which the current developed by the
machine is made to automatically put into the circuit the secondary batteries to
be charged
I sometimes employ an arrangement in which combined with a charging circuit
including a dynamo electric machine and a developing circuit are two series of
secondary batteries a working circuit common to both series and a switching

page_text: device for alternately connecting one series into the charging circuit coupled for
quantity to be charged and the other series into the working circuit coupled for
intensity to be discharged and clock mechanism (or its equivalent) for imparting
motion to the switching cylinder so as to effect the charging of one series of
batteries through the independent branches of the main charging circuit and the
discharge of the other series of batteries with their independent charging branches
disconnected from the main charging circuit wholly into the lamp or working
circuit coupled for intensity. I propose in some instances to run the dynamo
electric machine or generator which charges the secondary batteries by means
of an initial power or motor which acts at irregular intervals or periods such as
a wind wheel, a tide wheel or other variable source of power it being in such case
obviously necessary to employ means for switching the generating machine from
a developing circuit into the charging when the speed of the motor is at or about
normal and for switching said machine out of the charging circuit into the
developing circuit when the speed falls below normal in order to prevent back
flow of current from the secondary batteries from changing the polarity of the
field of force magnets.
I also propose to arrange the batteries of a series so as to be interposed
successively into the charging circuit and offer but slight resistance to the
establishment of the charging current.
When the windmill or other source of power is not sufficient to run the dynamo
generator at the required speed I use the windmill to pump water into a reservoir
and employ a syphon to empty the same periodically and act upon a water wheel
or water engine to propel the dynamo generator at the required speed for a
limited period of time and then allow the same to remain quiescent until a
sufficient volume of water has accumulated in the reservoir to again operate the
dynamo generator.
When the windmill is at rest the dynamo machine is also at rest and the spring
contact is in connection with the upper end of the rod and the circuit of the
machine is completed through the developing circuit but when the machine reaches
a certain predetermined speed the rod is inade to descend under the influence
of the governor and make connection with the lower spring contact so as to divide
the current through the developing and main charging circuit then to break
connection with the upper spring contact so as to direct the entire current into
the main charging circuit.
When but one battery is interposed in the charging circuit at a time it follows
that the minimum resistance is offered to the machine current when the same
is first diverted wholly into the main charging circuit from the developing circuit.
In order to regulate the length of time that each battery is charging I preferably
employ a circuit derived from the main charging circuit and including an adjustable
resistance, a clock, and an electro magnet.
It is obvious that in the employment of wind wheels, tide wheels or wheels in
streams, several wheels can be combined and grouped into one source of power to
drive one or more dynamo machines. Several wheels each working separate pumps
of approved construction could furnish a good supply of water from which to run
a wheel to propel a dynamo machine. The wheels could be made smaller and
a given power be obtained with less liability to breakage than if one very large
wheel were used.
From
The wheels driven by wind can be placed upon house tops where horizontal
wheels would be less objectionable on account of their better appearance.
such wheels, with an extra supply battery, the house could be illuminated, light
machinery propelled, bells operated and clocks maintained.
When desired to apply the system to a portion of a city or town the wind
wheels or tide wheels, located outside of the section to be lighted, can supply
secondary batteries located at various remote points from the electrical generating
machine and its propelling power and where currents of quantity with energy
sufficient to charge secondary batteries are conveyed over ordinary conductors,

page_text: there is no risk to life or property by accidental contact with the wires the
currents of energy being confined to circuits not liable to come in contact with
other conductors.
The employment of quantity currents of but sufficient energy to charge secondary
batteries requires less expensive conductors and insulation whether used on overhead
lines or with conductors buried in the earth.
It frequently happens that the wind power is sufficient to run a dynamo
generator constantly but in consequence of inequality in the wind the force is
sometimes too little and at other times too much. I equalize this force by
introducing a holder into which the windmill and its pump forces air, and this
becomes a storage for pressure to act in an engine or other motor to drive the
dynamo generator. I prefer such holder to be a floating weighted vessel within a
second water vessel similar to a gas holder.

CHARLES EDWARD BUELL, of New Haven in the State of Connecticut, United
States of America, IMPROVEMENTS IN SECONDARY BATTERIES OR STORAGE
BATTERIES AND IN THE METHODS OF AND MEANS FOR CHARGING AND
CHARGING THE SAME.
DIS-
The first part of my invention relates to an improved secondary battery and it
consists of a battery having one or both of its electrodes formed of globular or
spherical pieces of lead, carbon, or other suitable material such form of the pieces
enabling the largest amount of surface of a given bulk of material confined within
a given space to be exposed to the action of the exciting fluid or electrolyte
employed.
It further consists in constructing the battery of an outer cell of lead or
lead lined material and an inner cell of porous material placed within the outer
cell, both cells being filled with the globular or spherical pieces of lead, carbon or
other suitable material and a suitable exciting fluid or electrolyte such as salt and
water or sulphuric acid and water or other fluid and terminals of the battery
consisting preferably of binding posts connected to the outer cell or to the lining
or contents thereof and to the contents of the inner cell preferably through a plate
or wire of lead, carbon or other suitable material,
Figs. 1. 2. 3. & 4 represent different views of my improved battery. A is the
outer cell constructed of lead and having connected to it a binding post e. B. is the
inner porous cell of pourous earthen ware or other equivalent material Within the
porous cell is a bar or plate C. preferably of lead and having a binding post c¹. at
its upper end as shown. Both the inner and outer cells are filled near full with
the globular or spherical pieces of lead, carbon or other material D. D'. and with the
exciting fluid and a layer of paraffine E. is then applied for the purpose of
preventing the evaporation of the liquid contents of the battery. The paraffine
may be supplemented by an ordinary cover if desired This form of battery is
very easily and cheaply constructed. The spherical pieces constituting the
electrodes present to each other mere points of contact and afford a large surface
exposed to the action of the liquid and produce a battery of lower internal
resistance and of greater capacity than electrodes of like material of the same
weight but composed of other forms of pieces occupying the same space.
Furthermore the electrode can be formed of common lead shot of a given number
or grade; any person can readily produce a standard battery the quantity and
grade of the shot and the size of the cells being given. Batteries made in
accordance with my invention can be charged either by currents developed by
galvanic batteries or by dynamo electric machines or other electric generators and
they may be charged singly and discharged singly or charged singly and discharged
in series or charged coupled for quantity and discharged coupled for intensity or
charged coupled for quantity in multiple series and discharged coupled for tension
or otherwise. The series may be arranged to be alternately charged from the
same charging circuit and to be discharged into a common working circuit or one
or more of the batteries of a series may be charged while the others are
discharging.
Heretofore when secondary batteries have been charged by dynamo electric
machines it has been the practice to first speed up the machine on an open circuit
ind then close the circuit through the secondary batteries. Before the circuit is.

page_text: closed the armature of the machine merely gains momentum and but little
electrical power is developed, but upon the closing of the circuit the machine
develops power very rapidly. After a secondary battery has been once used it
remains thereafter partially charged and therefore when after first use the circuit

the machine develops sufficient power to overcome it and thus operates to change
the polarity of the magnets of the machine and renders the charging operation a
failure. To obviate the evils arising from this old mode of charging, I combine
with the dynamo-electric machine, a developing circuit in which the machine is
worked temporarily, a main charging circuit including the secondary battery or
batteries to be charged and means for dividing the current through the developing
circuit and the main charging circuit and then breaking the developing circuit
without breaking the main charging circuit. Referring to Fig. 5. A represents a
dynamo electric machine. a. a. the terminals of the helices of the field of force
magnets. B. the shaft of the revolving armature. C. the charging circuit, Da
secondary battery adapted to be interposed in the charging circuit. E. a shunt or
auxiliary circuit. J and h, respectively a hand switch and a contact in the
developing circuit and J' and h¹. respectively a hand switch and a contact in the
charging circuit.-Switch J. is on a contact h. and switch J. is off of contact h¹. when
the machine is started up, but when the requisite speed has been attained by the
machine the switch J'. is placed on contact h¹. and afterward switch J. is moved
from contact h¹. Instead of hand switches an automatic switching device operated
by the dynamo electric machine may be employed such for instance as shown in
fig. 6. In this arrangement O. represents a switch arm operated by a governor
which is geared to the dynamo electric machine. P. a segment having contact
plates p. p. Q. an adjustable resistance in a shunt or auxiliary circuit and D. the'
secondary battery to be charged. When the machine is at rest the switch rests in
contact with the plate p. thus closing the circuit through the shunt circuit and
cutting out the secondary battery but as the machine speeds up the governor causes
the switch arm to pass from contact plate p to contact plate p'. thus completing the
circuit through the secondary battery. Fig. 7, shows an arrangement in which the
current developed by the machine is made to automatically put into the circuit the
secondary batteries to be charged. In said figure R. represents an armature switch
adapted to engage with one or the other of contacts 7. r. to complete the circuit
either through the shunt circuit or through the secondary battery D. as the case
may be. The armature switch is acted upon on one side by an electro magnet S
interposed in the machine circuit and on the other side by another electro-magnet S.
in a local circuit containing an adjustable resistance T. and a battery as shown.
When the machine is at rest the armature is attracted by the electro magnet S.
thus closing the circuit through the contact . When however the machine is
started and the current developed by it causes the electro-magnet S. to overcome
the force of the magnet S. the armature shifts and puts the secondary battery D.
in circuit. By varying the resistance of the local circuit the resisting power of the
electro magnet S' can of course be regulated. As a substitute for the electro-
magnet S¹. a spring, weight or other like contrivance might be employed. A
resistance T. is also preferably interposed in the main circuit for the further
regulation of the movements of the armature switch.
In fig. 8. I show an arrangement in which combined with a charging circuit
including a dynamo electric machine and a developing circuit are two series of
secondary batteries, a working circuit common to both series and a switching device
for alternately connecting one series into the charging circuit coupled for quantity
to be charged and the other series into the working circuit coupled for intensity to
be discharged.

and closing it and C the charging circuit containing also an adjustable resistance e
and a switch f

page_text: 1, 2, 3 & 4, 5, 6 represent two series of secondary batteries D a working
circuit including electric lamps g, into which the secondary batteries are adapted to
be discharged E is a switching device by means of which one series of batteries
are caused to be interposed in the charging circuit coupled for quantity and the
other series into the working or lamp circuit coupled for intensity.
Said switching cylinder 7 has two series of metallic projections 888, a pair of
metallic projections 99 electrically connected to the shaft 10 which is in turn
adapted to be included in the charging circuit, two series of pairs of spring
contacts 11 11 11 and 12 12 12 adapted to make contact with the projections
9, 9, a series of conductors 13, 13, 13 each including one of the series of secondary
batteries 4, 5, 6 and when the pairs of contacts 11, 11, 11 are in connection with
the pairs of projections 99 constituting independent branches of the charging
circuit; and other series of conductors 14, 14, 14, each including one of the series of
batteries 1 2 3 and when the pairs of contacts 12, 12, 12 are in connection with the
projections 99 constituting other independent charging branches of the main
charging circuit, a series of pairs of spring contacts 15, 15, 15 having proper con-
nections (indicated by dotted lines), with the series of batteries 4, 5, 6, and with the
lamp circuit and adapted when in connection with one series of metallic projec-
tions 888 to interpose said series of batteries 4 5 6 in the lamp circuit coupled
for intensity and other series of pairs of spring contacts 16, 16, 16 having similar
connections with the series of secondary batteries 1, 2, 3, and with the lamp circuit
and adapted when connected to the other series of metallic projections 8, 8, 8, to
interpose said series of batteries, 1, 2 3 into the lamp circuit coupled for intensity,
and clock mechanism (or its equivalent) for imparting motion to the switching
cylinder so as to effect the charging of one series of batteries through the indepen-
dent branches of the main charging circuit and the discharge of the other series of
batteries with their independent charging branches disconnected from the main
charging circuit wholly into the lamp or working circuit coupled for intensity, I
propose in instances to run the dynamo-electric generator or machine which
charges the secondary batteries by means of an initial power or motor which acts
at irregular intervals or periods such as a wind-wheel, a tide-wheel or other
variable source of power it being in such case obviously necessary to employ means
for switching the generating machine from a developing circuit into the charging
when the speed of the motor is at or about normal and for switching said machine
out of the charging circuit into the developing circuit when the speed falls below
normal in order to prevent back flow of current from the secondary batteries from
changing the polarity of the field of force magnets. I also propose to arrange the
batteries of a series so as to be interposed successively into the charging circuit and
offer but slight resistance to the establishment of the charging current.
Referring to Fig. 9 A represents the helices of the field of force magnets of
the dynamo-electric machine; B the revolving armature of the machine; W a wind-
mill geared to the armature shaft so as to rotate the same E a shunt or developing
circuit H the charging circuit, 3, 4, 5 a series of secondary batteries adapted to be
interposed into the charging circuit as will be presently explained and 7 the
working or lamp circuit including electric lamps 8, 8, 11, represent spring contacts
and Al a rod adapted to be shifted by the moveinents of an ordinary ball-governor N
geared to the armature shaft as shown.
When the wind mill is at rest the dynamo-electro machine is also at rest and the
spring contact is in connection with the upper end of the rod M and the circuit of
the machine is completed through the developing circuit E but when the machine
reaches a certain predetermined speed the rod M is made to descend under the
influence of the governor and make connection with the lower spring contact U so
as to divide the current through the developing and main charging circuit then to
break connection with the upper spring contact / so as to direct the entire current
into the main charging circuit.
The switching devices employed in connection with the form of apparatus consist
of two rotary cylinders 27, 28 geared together so as to be rotated simultaneously

page_text: by automatic mechanism 29 of any preferred form, These cylinders are of metal
and are provided with the corresponding projections 30, 31, 32 arranged pro-
gressively as shown and their bearings are connected to the main charging
circuit H
The two cylinders are however electrically disconnected from each other except
when connected as further on explained.
33, 34, 35 represent several pairs of spring contacts which are adapted to make
connection when the cylinders are rotated successively with the pairs of projec-
tions 30, 31, 32, Each pair of these spring contacts is electrically connected with
the opposite electrodes of one of the series of secondary batteries. From this it
results, that when the cylinders 27, 28 are rotated the several pairs of contacts will
successively make connection with their appropriate projections on the cylinder so
as to successively interpose the batteries 3, 4, 5 in the charging circuit to be
charged and said batteries being all coupled together by means of the conductors
36, 36 discharge into the working or lamp circuit in tension series. Inasmuch as
but one battery is interposed in the charging circuit at a time it follows that the
minimum resistance is offered to the machine current when the same is first directed
wholly into the main charging circuit from the developing circuit.
In order to regulate the length of time that each battery is charging, I preferably
employ a circuit 37 derived from the main charging circuit and including an
adjustable resistance 38, a clock 39 and an electro-magnet 40.
The armature 41 of the 'electro magnet is pivoted at its outer end and its inner
end is adapted to engage with one or another of a series of pius 42 of the rotating
part of the motor 29 when said magnet is magnetized by the closing of the derived
circuit 37.
A spring 43 operates to retract the said armature when the same is released from
the magnet. During the charging of any one of the batteries the derived circuit 37
remains closed and the armature 41 engages with one of the series of projections or
pins 42, and prevents the cylinders from rotating, but after a certain predetermined
time has elapsed the clock 39 opens the circuit 37, whereupon the magnet 40
releases the armature 41 and the latter is caused by the spring 43 to disengage
from the pin 42 and start the cylinder into rotation and then by the time the next
pair of spring contacts come into connection with the next succeeding pair of
projections on the cylinders the clock 39 closes the circuit 37 thus again locking
the cylinders.
This operation is repeated each battery being in turn charged a certain length of
time
Figs, 10, 11, & 12 show different arrangements of mechanism for utilizing an
inconstant or variable source of power to run a dynamo electric machine employed
for charging secondary batteries
In figure 10 a wind mill W is arranged to operate an air compresser Z which
compresses air into an extensible air holder y from which it may be used to drive
one or more distant motors O adapted in turn to propel the dynamo electric
machine U, P represents the developing circuit of the machine adapted to be opened
and closed by a switch p. Q the main charging circuit opened and closed by a
switch q; R speeding down gearing geared to the armature shaft of the machine
arranged to operate at regular intervals, a reciprocating switch S for shifting
secondary batteries in and out of the main charging circuit
In figure 11 is shown an air holder with a valve lever L arranged to turn the
air from the air-holder to the motor O automatically when the holder becomes
filled to a given degree, Various other ways of arranging automatic valves are
obvious.
Figure 12 shows the wind-wheel W arranged to operate a water pump Z² so as
to fill or nearly fill a tank K through a pipe u. When the water in the tank
reaches a point above the curve in pipe U₁ a siphon is formed and the water
descending forces itself with great energy through a water-wheel O2 which wheel

page_text: drives the dynamo-electric machine with good effect to charge secondary batteries
as herein described and shown.
The beveled gears 9 7 can be varied so as to give the dynamo greater or less
speed as desired. The ball governor B G is shown upon the shaft of the water
wheel disconnected from the dynamo except through the wheels gg and actuates
the lever L to change the currents from a developing circuit at P2 to a charging
circuit at P¹
It is obvious that in the employment of wind wheels tide-wheels or wheels in
streams, several wheels can be combined and grouped into one source of power to
drive one or more dynamo-machines, Several wheels each working separate pumps
of approved construction could furnish a good supply of water from which to run
a wheel to propel a dynamo-machine. The wheels could be made smaller and a
given power be obtained with less liability to breakage than if one very large wheel
were used,
The wheels driven by wind can be placed upon house-tops where horizontal
wheels would be less objectionable on account of their better appearance.
From
such wheels with an extra supply battery, the house could be illuminated light
machinery propelled, bells operated and clocks maintained.
When desired to apply the system to a portion of a city or town the wind
wheels or tide wheels, located outside of the section to be lighted, can supply
secondary batteries located at various remote points from the electrical generating
machine and its propelling power and where currents of quantity with energy
sufficient to charge secondary batteries are conveyed over ordinary conductors,
there is no risk to life or property by accidental contact with the wires the
currents of energy being contined to circuits not liable to come in contact with
other conductors
The employment of quantity currents of but sufficient energy to charge secondary
batteries requires less expensive conductors and insulation whether used
overhead lines or with conductors buried in the earth.
