PROVISIONAL SPECIFICATION.
An Improved Method of Arranging Apparatus for Generating and
Distributing Electricity by Alternating Currents.
We HENRY ROBERT Low of 41 Beaconsfield Road St. Margarets,
Twickenham in the County of Middlesex Electrician and GEORGE EDWARD
BARKER PRITCHETT of Oak Hall Bishops Stortford in the County of Hertford-
shire Electrician do hereby declare the nature of this invention to be as follows:
Our invention relates to an improved method of arranging apparatus for
generating storing and distributing electricity and its object is to provide a system
which includes the following advantages.
The working of the motive power always at or near full capacity.
Storing of the electricity so as to be independent at times if necessary of the
motive power.
Distribution over extended areas by means of high tension alternating currents.
To effect this by means of our invention we combine the following apparatus.
1. Accumulators or storage batteries.
2. A direct current electro-motor which is also used as a dynamo coupled to an
alternating current generator (for convenience we will call this combination the
motor-alternator).
3. A steam engine or other source of power (which we will term the prime
motor) arranged by means of any suitable gearing such as a friction clutch or loose
pullies so that it may be connected to or disconnected from the motor-alternator
whilst either is in motion.
It will be seen that by arranging the foregoing apparatus in the manner
described the objects of our invention can be attained.
In the first place the prime motor can always be worked up to its full output as
when the amount of power required to drive the alternating generator is below the
full capacity of the prime motor the surplus power is used in driving the electro-
motor as a dynamo for charging the accumulators again at any time the prime
motor can be disconnected from the motor-alternator without causing a cessation of
the lighting as the current from the accumulators can be used to rotate the electro-
motor and drive the alternating generator or when the power required to drive the
alternating generator is in excess of the full capacity of the prime motor the
additional power can be furnished by the accumulators and electro-motor.

An Improved Method of Arranging Apparatus for Generating and
Distributing Electricity by Alternating Currents.
We, HENRY ROBERT Low of 41 Beaconsfield Road, St. Margarets,
Twickenham in the County of Middlesex Electrician, and GEORGE EDWARD
BARKER PRITCHETT of Oak Hall, Bishops Stortford in the County of Hertford-
shire Electrician, 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 :—
Our invention relates to an improved method of arranging apparatus for

page_text: generating, storing and distributing electricity, and its object is to provide a
system which includes the following advantages
-
The working of the motive power always at, or near full capacity.
Storing of the electricity so as to be independent at times if necessary of the
motive power.
Distribution over extended areas by means of high tension alternating currents.
To effect this by means of our invention, we combine the following apparatus:-
1. Accumulators, or storage batteries.
2. A direct current electro-motor which is also used as a dynamo, coupled to an
alternating current generator (for convenience we will call this combination the
motor-alternator).
3. A steam engine of other source of power (which we will term the prime
motor) arranged by means of any suitable gearing such as a friction clutch or
loose pullies, so that it may be connected to, or disconnected from the motor
alternator whilst either is in motion.
It will be seen that by arranging the foregoing apparatus in the manner
described, the objects of our invention can be attained. In the first place, the
prime motor can always be worked up to its full output, as, when the amount of
power required to drive the alternating generator is below the full capacity of the
prime motor the surplus power is used in driving the electro-motor as a dynamo
for charging the accumulators, again, at any time the prime motor can be
disconnected from the motor-alternator without causing a cessation of the lighting,
as the current from the accumulators can be used to rotate the electro-motor and
drive the alternating generator, or when the power required to drive the alternating
generator is in excess of the full capacity of the prime motor, the additional
power can be furnished by the accumulators and electro-motor.
The accompanying drawing shows a suitable arrangement according to our
invention:-
S. is a storage battery or accumulator connected by conductors L. L. to the
electro-motor M which is mechanically coupled to the alternating current
generator A.
P. is the prime motor arranged to drive the motor-alternator M. A. by means of
a belt B.
CD. is an arrangement of fast & loose pullies.
E. E are conductors through which the electricity generated by the alternating
generator A is distributed.
Having now particularly described & ascertained the nature of our said inven-
tion & in what manner the same is to be performed we declare that what we
claim is.
1. The combination of accumulator direct current electro-motor, alternating
current generator and prime motor as and for the purpose set forth.
2. The herein before described method of generating, storing and distributing
electricity by combining the several apparatus herein specified in the manner and
for the purpose set forth.
