AND MOTORS, IN BATTERIES IN CONNECTION THEREWITH, AND IN CARBONS
FOR OBTAINING ELECTRIC-LIGHT."
PROVISIONAL SPECIFICATION left by the said Richard Waller at the Office
of the Commissioners of Patents on the 25th February 1881.
RICHARD WALLER, of Leeds, in the County of York, Engineer. "IMPROVEMENTS
IN DYNAMIC APPARATUS AND MOTORS, IN BATTERIES IN CONNECTION THEREWITH,
AND IN CARBONS FOR OBTAINING ELECTRIC LIGHT."
My improvements in batteries consist in giving a rotary motion to plates of zinc
or copper, zinc or graphite, or any suitable materials, immersed in any of the well
known fluids used in batteries, and for this purpose I prefer giving these plates a
circular form, as discs or cylinders, and I also prefer to work the same under
pressure from air or gas. I make suitable arrangements for the continuous removal
and renewal of the fluids or liquids or other material used.
I will now describe my improvements in motors.
place my armature between two magnets, as usual, but instead of being equi-
distant from the poles I propose to place my armature so that it is always in
contact with one limb of each of the magnets, between which it has an alternate
or reciprocating motion, the upper end being at a distance from these magnets
regulated by the length of stroke it is desired to obtain.
My armature will be in connection by its upper end with the crank of the
fly-wheel by means of a connecting rod of special construction. I propose to
construct and arrange this connecting rod so that when the fly wheel has made
half a revolution under the impulsion communicated by the armature through this
rod the rod will be arrested by coming into contact with the magnet which
determines its stroke, and the fly wheel continue its revolution by its initial force
until the revolution of the crank brings the armature within the influence of the
opposite magnet, the magnet or magnets with which it was first in contact having
been demagnetized, and so on. It will be evident that I only require a series of

page_text: armatures and magnets to carry the fly wheel from point to point, whatever may
be the magnitude of the engine.
By keeping my armature always in contact with both magnets the armature
remains always to some extent magnetized, and thereby I obtain, as it were, a
permanent store of magnetic action instead of a constant renewal, as is the case
when the armature and the magnets are at a certain time wholly disconnected and
the magnetic power is scarcely felt until after the armature has travelled a certain
distance towards the magnets.
1
In my arrangement the stroke, which is determined by the distance at which
the magnets are placed from each other, allowing the distance necessary for the
space which the armature will take up, it will be seen that the armature can only
give one half the revolution, but the arrangement of my expanding connecting rod
will allow the fly wheel to make the other half of its revolution by its initial force,
as above set forth. It will be understood that the armature might be composed of
magnets with reversing poles or otherwise.
My improvements in dynamic apparatuses consist, firstly, in coiling a hollow
cylinder of malleable or cast iron, which, as it is stationary, may be denominated
the field magnet, in which I work a series of bobbins covered with wire, through
which I pass an axle longitudinally, this axle having flanges and suitable bushes
made in it, so that the spindles or extended ends of the bobbins can work therein,
each bobbin having at one end a pinion or other driving gear, which will work in
an inner wheel toothed interiorly, or a stationary wheel through which the axle
may revolve, and these wheels acting as pinions on the spur wheel so placed, or
these bobbins may be divided, each of them having a core and being properly
insulated, are placed upon their spindle; the poles of each will be connected with
properly arranged commutators at the opposite end of the spindle to that which
carries the pinion wheel. The hollow cylinder above alluded to will in this instance
have projections which will communicate magnetic effect to each pole of the
magnets on the spindle arranged negative and positive. At the outer end of the
field magnet I place a number of segments in the form of a ring, each segment
forming a pole and fixed to the flanges of corresponding divisions of the field
magnet, whereby I have revolving magnets radiating from the axle, the poles of
which I alternately reverse. Thus I accelerate and add to the electrical energy of
the apparatus. When I divide the cylinder into segments or bars I lap each
division with wire longitudinally and make it with flanges directed inward and
insulated from each other. I may also have a cylinder with fixed bobbins working
within it and insulated from each other, or I may have revolving bobbins, as above
described.
Or I may make my field magnetic arrangements like an elongated cylinder in
divisions, the end divisions being of a semi circular form and the intermediate
divisions being composed of straight bars, which may be coiled in connection with
or separate from each end and from each other, being insulated at the junction or
placed sufficiently wide apart; these bars are properly supported by a frame, in
which bobbin armatures work actuated by suitable gearing from any source of
power. It will be evident that disc armatures may be used in a similar
manner.
These principles of construction may be modified to suit discs formed so as to
have revolving magnets in the stationary field magnets, and that the armature,
which may also be called a disc, may have revolving bobbins or magnets, the discs
working in the closest possible proximity with the field magnets.
I use any suitable connections to the commutators and for makes and breaks.
My improvements in carbons for electric lighting consist:-
In making the carbons in a spiral, zigzag, or other analogous form, whereby I
obtain a great length of carbon occupying a comparatively small space as compared
with the straight carbons now used; these I may work either in the open air
or under cover in vacuum in glass vessels, using the usual or any suitable
connections.

page_text: I propose to set my electro-motor at work by either a dynamic generator or by
a battery of requisite power, and to give any excess of energy so developed beyond
what is required for lighting to the magnets for working my motor.
I may also use a motor consisting of a number of electro-magnets placed on a
bed or frame making a flat plane; on the surface of the said magnets I arrange a
moveable armature, which has an upright lever fixed to the armature or to a frame
having a corresponding number of magnets fixed therein; this armature is slightly
sloped to obey a short segment of a large circle. This upright lever will have a
similar connecting rod to that of the motor first above described differentially
fixed to the fly wheel, allowing one half the revolution to be accomplished by the
impetus the wheel has received in the leading first half of the revolution. There
are steadying rods and a frame in which the connecting rod fixed on the upright
lever works, which keeps the lever firmly in a direct line with the crank of the
fly wheel. Of course this arrangement works in consequence of the magnets being
magnetized and demagnetized alternately.
Another modification is that of a number of magnets placed within a circular
hoop, which radiate to the centre; they are fixed side by side to each other; the
magnets are flat on their poles. A ring of soft iron, the width of which is equal
to the poles of the magnet, has its periphery equally divided into as many flat
portions as its diameter will admit of, which divisions must be exactly as long as
the two poles of each magnet. The ring is the armature and works excentrically
to the magnets and the shaft. A short crank is placed on the shaft having a pin
or stud on which the armature revolves. Motion is given by magnetizing and
demagnetizing the magnet. Several magnets are induced in advance of the
armature in addition to the one in contact with the armature, which is demagnetized
on the instant the armature leaves it, and so on.
I may use the whole of my improvements in combination the one with the other
or separately with any of the apparatuses already in use for similar purposes,
whether dynamic, battery, or other engines actuated by steam, gas, air, or other
motive force.
I purpose applying my improvements to the lighting of private dwellings,
studios, and other apartments, as well as to exterior lighting of any required
conacity

IMPROVEMENTS
IN DYNAMIC APPARATUS AND MOTORS, IN BATTERIES IN. CONNECTION THEREWITH,
AND IN CARBONS FOR OBTAINING ELECTRIC LIGHT."
My improvements in batteries consist in giving a rotary or other motion to plates,
cylinders, or other forms, whether compositions or otherwise, of materials and metals
used in the production of currents negative and positive electricity thereof. I have
various, modifications of vessels suitably formed for carrying out the means by
which I give motion to the various forms required in batteries. The first modifi-
cation consists of discs of round flat plates; the surface may be corrugated
concentrically to the axis which will increase the surface in a given space in contact
with the elements.
The outer cell or case is of strong earthenware, glass, cast iron, with coating of
enamel impervious to the attack of acids, gutta percha, and, in some cases, vulcanized
india-rubber products such as ebonite, which will be understood by reference to the
Drawings.
For simple notions to be abandoned by moving plates up and down or forward
and backward or to move round to a certain distance and back again, I use the well
known instrument in contrivance as the roasting jack, which can be wound up
when its power is expended, and I place the same in any convenient manner; or I
use the ordinary jack which is self acting; or by simply winding a cord round- a
roller supported by two uprights held together by fixed crap pieces, and on one or
other of the upright pieces I have a spindle arranged, at the upper end of it a mitres
wheel which gears with a fellow mitre wheel, which are fixed on a spindle or shaft,
which are arranged on the cross piece which binds the two uprights. A cord
wound on the roller may have a weight to it, and a pulley on the roller, and with a
pulley on the cross shaft with a cord belt round both rollers, pulley, and cross shaft
pulley when put in motion will actuate the plates or cylinders of the batteries in
the following manner :-A cross piece of wood or metal which is fixed below the
upper crosspiece which binds the two uprights have holes toothed or otherwise to
receive the spindle which is connected to the loop handle which crosses over the
zinc cylinder (but this spindle can continue to the graphite or carbon or other
material in the porous cell and have motion given to it), which spindle can be made
to enter a socket forced to the graphite or other material, and a set screw in the
socket can fix the spindle therein at will when motion can be given to the zinc and
the graphite at the same time, Figure 1 (Sheet 1). a, the general cell or vessel
which contains the zinc disc c and the copper disc d and also the porous that
divides the vessel and separates the zinc e and the copper d'; m, m, are the inlets of 4
fluid, and b, b, are the outlets. These passages are placed in their position for
connections to be made thereto with tubes from the pump which supplies the new
whilst takes away the fluid which has been used in the battery; b' makes the
connection with the copper disc d, and b² makes the connection with the zinc disc c;
d is a ring soldered on the copper, against which the pin b' is caused to be pressed 4
by means of the springs, the binding screws 63, 63. The zinc disc c has also a ring c¹,
and the pin 62 is caused to be in contact as described, and acting so as to liberate
the current generated in the two discs by the two wires J, J, fastened in the binding
screws 63, 63, R, R, fastened in the binding screws 63, 63; R, R, are the blowers
as fans, which are actuated by the pulleys h, h, placed in this position to
keep down the temperature of the plate while the motion presents polariza-
tion. Figure 2 (Sheet 1) is a side elevation of Figure 1; Figure 3 (Sheet 2)
is a modification of battery so arranged horizontally to give motion at any

page_text: required velocity to annular cylinders, solid, hollow, or in segments or pieces;
a is the general vessel or cell; B is the porous cell; C is the annular ring cylinder;
d, the core of carbon or positive element; e is the socket in which carbon or other
materials are fixed; f, the spindle by which the carbon d is made to revolve; g, g,
are stuffing boxes and glands to prevent the liquid from escaping when the. batteries
are under pressure or otherwise; H, H, the pullies; J, the spindle, the zinc cylinders c
is fixed; J, J, the two standards to carry the spindles f and I; K is the well into
which the liquid falls to facilitate precipitation of double salts during the motion of
zinc c and the carbon or other material; an angle is given to the well k, and at 7 a
gutter is made to facilitate said liquids away through the cock m, and the vessel n
contains the required supply to keep the quantity necessary for the changing of
the liquids o, the vessel into which the used liquid runs through the cock m by
which the quantity required is regulated.
To change the liquids. I have tanks which hold the quantity, and if pressure be
required the said tanks or other suitable vessels or vessel may be placed at a much
higher line than the battery, even so high as to set as a column of liquid, Figure 2.
The pump is for the purpose of forcing air, gas, or fluids into the battery or
batteries; but I prefer to cause a stream or flow of the liquid of the batteries or
battery, thereby presenting any local action injurious to the full. force of the
elements in said batteries. On the basis of my patented improvements in obtaining
motive power and in apparatus connected therewith, sealed the Nineteenth April,
One thousand eight hundred and fifty nine, and dated the 22nd October 1858, I
have further improved and rendered more effective my present arrangements in
connection with batteries.
No. 2, Figure 1 (Sheet 2), shows double battery and the pipe connected with
column before alluded to and described; q is the circulating pump; a, the general
cylinder; c, annular zinc cylinder; b, the porous cell; d is the carbon.
I will now proceed to describe my improvements in dynamic machines and
apparatus connected therewith. Figure 1 (Sheet 3) illustrates my arrangement of
a dynamic electro. machine with one armature composed of two hollow and one
solid magnets on each side of the armature. In reference to the Drawing in
section No. 3 the peculiar way they are fixed is shown. The outer magnet a is
covered with wire, as seen on the opposite side to that in section; the coils;d, d,
nearly cover the one half, and if the side in section were covered there would only
be the pales d, l, uncovered with wire; the object of this arrangement of magnets
is to increase the number. Magnetic pulsation and to increase the energy and the
production of mechanical work. The armature B is in six sections. Each section
is a separate magnet. The core on which the wire is coiled can be hollow so as to
receive pieces of turnings, cast or wrought iron, or pieces of wire. Two checks
a', a², are fixed and are joined to the wood which forms in smaller machines the
insulated, and in which grooves, are cut to receive the copper connections which
unite the wires of the coils of the armature and the commutator. The cheeks
herein alluded to are shown in section No. 2, at h, h, so that the armature works
nearly all of it covered by the outer field magneto or magnet.
Figure 2 (Sheet 3). No. 1 is a modification of a dynamic machine arranged with
two armatures, and is worked either with belts or gearing; but to secure certainty
of motion for both armatures I place on the shaft of each armature a spur or pinion
wheel with teeth of peculiar shape, but which are suited to bigh velocities.
Between the two wheels I place a carrier wheel of the same form of tooth of course.
It will be seen that if the belt were to slip on one pulley (as it is frequently the
case) to do so, the whole four would do so at the same moment, but the chances are
that one belt round one pulley may not slip at the same moment. No. 2. This
modification shows two sets of two bars a, a, arranged to receive three armatures
b, b, b. The bars a, a, will be coiled with wire in the manner seen at a at No. 2.
Figure 3 shews a modification of four armatures, two of which can induce field
magnets and the other two can supply the centre light or otherwise as required.
The four carrier wheels will be governed by a centre wheel or fifth carrying wheel d.
-'

page_text: The field magnets g. a, a, are electro magnets fixed to a circular frame of wood c
to radiate inwardly; b is an armature a little less in diameter, and which it is
placed it is in contact with one magnet, consequently it is then eccentrically
positioned to the common centre of the magnet when the magnets No. 1, 2, 3, 4, 5,
are electrized, and the whole of that number in succession only, and last one of the
number demagnetized the armature with only the attraction, and will roll with its
periphery to the surfaces of the magnets, and rapid revolutions will result.
C, the socket at the end of the ball and socket e, e, (which actuates the make and
break or communicator) in the armature b. The larger ball and socket f, f, is the
fulcrum of the lever g, which gives motion to the fly wheel shaft h; i, i, are the
standards which support the fly wheel.
No. 2. In this modification the electro magnets are in pairs, radiating inwardly,
and the armature is a little less in the flats thereof than the surfaces of the
magnets; A, A, are the magnets; b is the armature; C, is the frame. The action
of the armature b and the magnets A in this modification is exactly the same as
the one already described.
!
No. 3 A. The armature is composed of two magnets, and is made to rock between
the magnets 61 and 63; and b, b 2, the two magnets of the armature Q, have their poles
reversable. The connecting rod d is contrived so as to become longer and shorter,
moving the same distance every stroke, and by this arrangement the rod is in its
movement differentially acting to the crank of the fly-wheel.
The connecting rod x d and d 1 has a piston e; when the armature is in the
center between the two magnets the crank x 7 has been forced to the position
where it now stands by the piston e pushing against the head rod x 11, and as
soon as the crank is pushed directly over the centre, the armature at that 'moment
will be in the strongest contact with the magnet 61, 62, when the initial force of
the fly-wheel will draw the cylinder d 1 to the piston e, the piston being stationary
for the moment until the crank has arrived at quarter centre, in which time the
magnets of the armature have had their poles reversed, and the armature is on its
return back to repeat the same conditions. It will be seen that by this arrangement
the full force of the pull of the magnets has been entirely accomplished, The
motion of the fly-wheel is in the direction of the arrow. The commutator is
arranged on the bed at f, and the making and breaking is done by the motion of the
eccentrics C worked on the shaft of the fly-wheel e.
No. shows another rocking arrangement with magnets arranged on each side
of the lever a. The whole may have their poles reversed, or one range may be
permanent magnets.
Fig. I., No. 1 shews the cylinder A in which the carbon when it is in a
sufficiently soft state so that its consistence is in a properly firm and stiff condition
that when it is under the great pressure of ram 6 the mixture will be so substantial
when it leaves the volute or curved nozzle c it will remain in its spiral form and will
stand the processes of high heating or baking. The cup d is the place in the cylinder
where feeding the same takes place; e is the table formed of a segment of the
diameter of the spiral candle. At fit will be seen the cone into which the carbon
is forced, and its dimensions as to its diameter there determined before its spiral
form is given g the worm which actuates the worm wheel h. The worm can be
turned by either hand or steam or other power; c the strong jaws between which
the worm wheel revolves, and by that motion the screw j moves forward the ram
which is prevented from turning round by reason of a stationary key; the key
way K can be seen in the jaws i; b, the bed; m, the bushes, in which the shaft of
the worm runs.
Fig. 2, No. 1. A is the spiral candle, is divided into two parts, and the substance
is proportionably larger in the positive spiral to, and in the negative spiral less, as
a matter which is understood.
The balls d, d, are suspended by each of them being hung by a small card e, e,
which I wound round the sliding disc j, j, to which discs are cemented the spirals.
It will be understood that the spiral candles as they consume the balls d, d, keep

page_text: the points so as to keep the arc constant, and as the spirals revolve the guide
pins ff. The binding screws g, g, hold the wire which communicate the
electric current to cause the light; K, K, are the uprights which support the spiral
on the bed 1, the ends of the cradles m, n, where the arc is indicated. It will be
seen as the discs j,j, revolve the slide on the spindle o, o. I need scarcely observe
that I use commutators and arrangements for the proper distribution of the electric
currents with brushes, or otherwise will be connected acccording to the requirements
for its application.
Having now described and ascertained the nature of my said Invention, and in
what manner the same is or inay be performed, I would have it understood that
