Means of Maintaining and Renewing the Charge of Electric Accu-
mulators Working Motors for Carriages, Boats, Balloons, and
other Vehicles.
I, PAUL EMILE RACET, of 18, Rue Denfert-Rochereau, Paris, France, 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 follow-
ing statement:-
The electric carriage is certainly the most simple and agreable of all moto
vehicles.
Unfortunately it has a great inconvenience. Its run is very limited and at
the end of this run, a source of electricity has to be found and considerable time
has to be lost for charging the accumulators.
I avoid this inconvenience by charging the accumulators during stoppages and
likewise while travelling.
For this purpose I carry with the accumulators a small dynamo so constructed
as to give very low voltage and as many amperès as possible, as in dynamos for
electrolysis.
This small dynamo charges on the one hand the accumulators grouped in
quantity, and then on the other hand these same accumulators are employed and
discharged in tension for the electric motor which turns the wheels of the vehicle.
This small dynamo which is made with very large wires and which is consequently
very strong, is worked by a very small light motor which may be worked
by petroleum, alcohol, acetylene, hot air, ammonia, fusing powders &c.
The charge of the accumulators being thus maintained and renewed on the
vehicle itself great advantages result, especially
1. The distance that can be run with an electric vehicle is much increased.
2. It is no longer necessary to store a very large quantity of electricity; con-
sequently the weight of the accumulators may be greatly lessened, which more
than compensates for the weight of the small dynamo and its motor.
3. No time nor electricity is wasted in going to a source of electricity, often
very distant, to charge the accumulators.
4. Finally there is no longer any risk of having to lie by after the charge
of the accumulators is quite exhausted, since they can be charged again on the
spot.

page_text: Almost all the metallic parts of the dynamo and motor are of aluminium
or in very strong alloys of chromium; this rendering the whole exceedingly
light.
The dynamo and its motor are carried on springs so as to give no vibration to
the vehicle.
What I have said as to electric vehicles applies equally to pleasure boats and
small boats which run for only part of the day.
It applies also to balloons, flying machines &c.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:
On carriages, boats and other vehicles having motors worked solely from
accumulators, the employment of a dynamo of low voltage and a motor for working
it, for maintaining or renewing the charge of the accumulators; either during
stoppages or while running, this dynamo charging them in quantity whilst they
are discharged in tension working the motor of the vehicle.
