PROVISIONAL SPECIFICATION.
An Improvement connected with Electric Lighting Apparatus.
I, GEMINIANO ZANNI, of 64 Gibson Square, Islington, Middlesex, Electrician,
do hereby declare the nature of this invention to be as follows:-
This invention has for object, the lighting of incandescent electric lamps from a
secondary battery charged primarily and afterwards fed to compensate for leakage
from a magneto, a dynamo, or other like agent actuated by an electric motor, or
by clockwork, springs, or other contrivance suitable for the purpose of giving
rotation.

COMPLETE SPECIFICATION.
An Improvement connected with Electric Lighting Apparatus.
I GEMINIANO ZANNI of 65 Gibson Square, Islington, Middlesex, 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:-
This invention has for object the lighting of electric lamps from one or more
secondary batteries charged primarily and afterwards fed by switching either or
any number on for feeding and thus to compensate for leakage or exhaustion from
a magneto, a dynamo or other like agent actuated by an electric motor or by
clockwork, springs or other contrivance suitable for the purpose of giving rotation.
In combination with the foregoing arrangement or system I employ a trans-
former between the electric motive force and the lamp or the accumulator for
increasing the tension of the current or according to the lam employed I use an
induction coil to reinforce the current.
To enable my invention to be clearly understood I annex a diagrammatic drawing
hereto in which A A represent two secondary batteries.
B, a magneto or dynamo, C, an electric motor, D a transformer E, a lamp.
Suppose one of the accumulators to be charged primarily the shunt current a, b,
excites the coils D drawing down the armature E into contact with the terminal F
thus switching into action the motor C, which in turn drives the dynamo B the
current from which either passes through the lamps into the accumulator or
into the accumulator direct. While one section of the accumulator is being dis-
charged the other is being charged from the dynamo under the control of the
coils D. D.
I purpose using an automatic switch which shall act for changing the direction
of the current to the secondary batteries when the exhaustion of either takes
place.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The improvement hereinbefore described viz. the employment of secondary
batteries to rotate electric motors and the electric motors to rotate the dynamo or

page_text: dynamos or magneto or magnetos for the purpose of renewing the charge of the
accumulators or pass direct to the lamps as set forth.
