NEW OR IMPROVED ELECTRICAL ARRANGEMENTS WHEREBY ELECTRICITY CAN BE
APPLIED IN INCREASED AMOUNT OR FORCE."
My Invention has for its object the inducing of electricity from electrical arrange-
ments, whereby an increased force or quantity of electricity or current is obtained,
so as to practically induce greater force or forces or current than from the original
source.
In carrying out my Invention, I adopt mainly the following arrangements :-I
use condenser or condensers or other inducing bodies or means so arranged that
one surface of the first condenser or condensers is in conducting communication.
with one pole of a source of electricity, and the other surface of the said first con-
denser or condensers is in conducting communication with a surface of a second
condenser or condensers, and the other surface of the second condenser or condensers
is in conducting communication with a third condenser or condensers. The third
condenser may be similarly connected with a fourth condenser, and so on to any
required number, it being understood that the last surface of the last condenser or
condensers or other inducing bodies or means is in conducting communication with,
the other pole of the source of electricity, or put to earth, as in the usual manner.
The surfaces of any of the condensers then, by conductors, deliver electricity for
any purpose that may be required, the conductor from one surface of a condenser

page_text: or condensers being one pole, and the conductor from the other surface of the same
condenser or condensers being the other pole, and when these said conductors
are connected-together a current passes which may be used in any desired way.
To prevent the condensers from not charging each other-on-account of excess of
charge of any condenser (caused by having too great a resistance between its con-
ductors), an electro-magnet may be placed in the circuit, when the current falls too
low, the electro-magnet-lets-back_an_armature, which in moving works a rheostat
or other resisting medium or mediums of varying resistance, such-resisting-medium
or rheostat being in derived circuit, and in working makes its resistance vary, so as
to keep a current passing continually or at intervals between the surface of the.
condensers, or practically to discharge them so as to prevent any condenser having
excess of charge.

the said James William Thomas Cadett in the Great Seal Patent Office on the

"NEW OR IMPROVED ELECTRICAL ARRANGEMENTS WHEREBY ELECTRICITY CAN BE
APPLIED IN INCREASED AMOUNT OR FORCE."
My Invention has for its object the inducing of electricity by means of electrical
arrangements which apply the amount or force of electricity or current in such a
manner that thereby such amount or force is increased as regards its practical
efficiency.
In carrying out my Invention, I adopt substantially the following arrange-
ments :-
I use a condenser or condensers or other inducing bodies or means so arranged
that one surface of the first condenser or condensers is in conducting communication
with one pole of a source of electricity, and the other surface of the said first con-
denser or condensers is in conducting communication with a surface of a second
condenser or condensers, and the other surface of the second condenser or con-
densers is in conducting communication with a third condenser or condensers. The
third condenser may be similarly connected with a fourth condenser, and so on to
any required number, it being understood that the last surface of the last condenser
or condensers or other inducing bodies or means is in conducting communication
with the other pole of the source of electricity, or put to earth as in the usual
männer. The surfaces of any of the condensers then, by conductors, deliver
electricity for any purpose that may be required, the conductor from one surface of
a condenser or condensers being one pole, and the conductor from the otlier surface
of the same condenser or condensers being the other pole; and when these said
conductors are connected together a current passes which may be used in any
desired way: To prevent the condensers from not charging each other on account
of excess of charge of any condenser (caused by having too great a resistance

page_text: between the conductors), an electro-magnet may be placed in the circuit of any
condenser; when the current falls too low, the electro-magnet lets back an arma-
ture, which in moving works a rheostat or other resisting medium or mediums of
varying resistance, such resisting medium or rheostat being in circuit, and in
working makes its resistance vary so as to keep a current passing continually or at
intervals between the surfaces of the condensers, or practically to discharge them so
as to prevent any condenser. having excess of charge.
Having thus far described the nature of the said Invention, and incidentally
intimated in what manner the same is to be performed or put in practice, I will
now proceed to more particularly describe and ascertain in what manner the same
is to be performed or put in practice by reference to the accompanying Drawing,
which represents a series of three condensers connected as therein shown.
DESCRIPTION OF THE DRAWING.
The condensers are marked A, B, and C; one of them (A) has one of its poles or
surfaces or set of plates connected by a conductor with one pole of a source of
electricity (S), the other pole or surface or set of plates or sides of the condenser A
being connected with one pole, surface or set of plates or sides of another condenser
B; the other pole, surface, or set of plates or sides of the condenser B being similarly
connected with a third condenser C, and the external pole, surface, or set of plates
of C is connected with the other pole of the source of electricity S. Conductors
are connected to the opposite sides of the condensors, as shown by a¹ and all for
the condenser A.; b, b, for B, and c, c¹¹, for C; the respective couples forming
circuits for delivering electricity for any required purpose; for instance, a¹ and all
forming a circuit, a' being one pole, and all the other, and similarly with b¹, bu,
and c¹, cl
Between a and all, and in circuit, a rheotome or circuit breaker may be placed,
also one between 6 and 611, and oue between c¹ and c¹, and one may be placed
directly in the circuit of the source of electricity (S) at either pole desired between
S and A, or between S and C, or a rheotome or contact breaker may be used in the
circuit of the source, and rheotomes or circuit breakers not used between a¹, a¹¹, 1,811,
and c', cll.
In place of the said rheotomes or circuit breakers, and to avoid sudden breaking
of the current, arrangements can be made by which an electro-magnet, by moving
an armature, can be made to vary a resistance in the circuit evenly, or in waves, as,
for instance, if such armature caused a conductor of suitable resistance to vary its
immersion in mercury, thus increasing and decreasing its length, and thereby in-
creasing and decreasing its resistance, or if the electro-magnet caused such armature
to vary pressure on any suitable material, resistance could thereby be varied, or any
other known method of varying such resistance could be used, there being many
well-known methods of varying or breaking a current of electricity.
I will suppose that a source of electricity is in connection with the condenser A
as described, there being a rheotome or circuit breaker in circuit. I will also
suppose that the condenser A is in connection with the positive pole of the source S.
The pole or surface or set of plates or sides of the condenser A in connection with
the source S will be charged positively, the other pole or surface of the condenser A
will be charged negatively by induction, and a positive charge will flow to the
condenser B from the negatively charged pole or surface or set of plates or sides of
the condenser A; the same conditions will apply as regards the condensers B and C,
the external pole or surface or set of plates or sides of C being in connection with
the negative pole of the source (S) or put to earth. Suitable resistances, or the
required means for work to be done, are placed between the conductors a¹, a¹¹, b¹, b¹¹,
and c, c, of the respective condensers. This example of arrangement supposes
that there are no rheotomes or circuit breakers or means of varying the current as
above described between a', a¹¹, b1, b¹¹, and c', c. When the rheotome or circuit
breaker between the condenser A and the source S is caused to make or makes

page_text: connection between S and A, the condensers A, B, and C become charged according
to the suitable resistances between them. When they are charged, the rheotome or
-circuit-breaker breaks contact or increases the resistance between S and A. Tho
condensers then discharge themselves, or-do-work-through the resistances or means
of work interposed between a¹, a¹¹, 61, 6¹¹, and c¹, c¹¹. After the required discharge,
the rheotome or circuit breaker again makes connection between S and A, and so on.
Or in addition-to-the-rheotome or circuit breaker at R, rheotomes or circuit
breakers may be placed between a, a, b, 6" c¹c, and -preferably when the
rheotome or circuit breaker R makes contact, the rheotomes or circuit breakers
between a¹, a¹¹, b¹, b¹¹, and c¹, c¹¹, should break or be caused to break contact, and
vice versa. It must be understood that the rheotomes or circuit breakers may be
dispensed with if desired, though I prefer to use them, as I am unable to feel con-
fidence that the increased practical efficiency to be attained by the use of my-
Invention will be obtained when they are dispensed with.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the arrangements applicable to and manner
of using condensers, substantially as and for the purposes herein-before set forth and
described.
In witness whereof, I, the said James William Thomas Cadett, have hereunto
set my hand and seal, this Twenty-sixth day of April, in the year of our
Lord One thousand eight hundred and seventy-nine.
