Improved Means for Controlling, Transforming, Regulating,
Synchronizing, and Registering Electric Currents..
I, HENRY EDMUNDS, of 10 Hatton Garden in the County of Middlesex, Electrical
Engineer, do hereby declare the nature of this Invention to be as follows:-
The object of my Invention is to provide efficient means for controlling transforming
regulating synchronizing and registering electric currents so that for instance.
currents of one kind can apart from the generator be converted into currents of a
different character for any required purpose such for example as the transforming of
an alternating current into a continuous current for storing secondary batteries
operating motors or for any other required purpose and I will explain my Invention
in that connection. The alternating current is passed through a series of magnets:
with poles alternately reversed and in proximity to this series of magnets is another
corresponding series of permanent magnets or of electro-magnets magnetized from
any convenient source. These two series of magnets have motion (by rotation or
vibration for instance) relatively to each other and obtained from any convenient
electric or other motor; in connection therewith is a commutating arrangement to
which the alternating current to be transformed is led and by the brushes or collectors
of which it is taken off as a continuous current. The moving part or parts may also
be connected to a counter for registering purposes. A convenient arrangement is to
make the series of magnets magnetized by the alternate current a circular series
within which is situated the other series mounted upon a rotated shaft and upon the
same shaft is the aforesaid commutator and also a counter if so desired.
The series of magnets and commutator are relatively arranged so that the
plus and minus impulses are transferred to each brush respectively and the said
series of magnets will act as a governor or synchronizer applicable to various
purposes.

1 HENRY EDMUNDS of 10 Hatton Garden in County of Middlesex Electrical
Engineer do hereby declare the nature of this Invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
The object of my Invention is to provide efficient means for controlling transforming
regulating synchronizing and registering electric Currents so that alternating currents
can apart from the generator be converted into continuous currents for any required
purpose such for example as for storing secondary batteries for operating motors for
lighting or for any other required purpose and I will explain with reference to the
accompanying diagram my Invention in that connection.
The alternating current is passed from the generator or from the secondary circuit
in a coil as indicated at A through a series of magnets B B arranged with poles
alternately of reverse denomination and in proximity to this series of magnets B B
is another corresponding series of permanent magnets or of electro magnets C
(only one of which is shown) magnetized from any convenient source such as from
the battery c.
These two series of magnets B and C or one of them have or has motion (by rotation
or by vibration for instance) relatively to each other and obtained from any convenient
electric or other motor such as by rotating the magnets (by carrying them on the
shaft of the motor E which may be supplied with a driving current by the battery c
which in turn is charged from the same source (A) as that from which the lamps F (or
other translating devices) are supplied.
On the shaft e of the motor is a commutating arrangement D to which the
alternating current to be transformed is led by the leads 1. 1 and contacts 2. 2. and
by the brushes or collectors d d of which it is taken off as a continuous current
which is utilized in the circuit 3. 3 for any desired purpose such as to light the lamps F
and charge the battery c. the battery furnishing current to the motor E as aforesaid
by the wires 4 and by the circuit 5 and commutator 6 exciting the electro
magnets at C.
The moving part or parts may also be connected to a counter (indicated at E¹)
for registering purposes.
The series of magnets and commutator are relatively arranged so that the plus
and minus impulses are transferred to each brush respectively and the said series of
magnets will act as a governor or synchronizer applicable to various purposes, as if
the motor be not of sufficient power (relatively to the power of the current in B B),
to alter the driving of the electro-magnet C it is impossible that the latter should fail
to run in harmony with the periods of the alternating currents in B B and thus the

page_text: apparatus may be used as a governor or synchronizer because any mechanism to
which it may be attached is governed by or synchronized with the current in the
secondary coil of A which in turn can be regulated by current from a central station
over the main X X.
The magnets B should be arranged as in the diagram face view at Z so that the
respective poles of the magnet C come opposite poles of B of opposite denomination
Having now described and particularly ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what I
claim is,
First For controlling transforming regulating and synchronizing with or without
also registering electric currents the arrangement and combination of means
substantially as hereinbefore described.
Second In apparatus or means for transforming electric currents two series of
magnets and collectors or brushes arranged and operating substantially as herein-
before described.
Third In apparatus for transforming or for transforming governing or syn-
chronizing electric currents the combination of two series of magnets arranged one
within or in proximity to the other and relatively moveable with respect to each other
by a motion of rotation in combination with a commutator and brushes or collectors
with or without a Counter substantially as hereinbefore described.
