A communication from abroad by THEODOR STORT, of Berlin in the Empire of
Germany, Engineer.
I, ALFRED GEORGE BROOKES, of 55 & 56, Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
to be as follows:-
Motor cars carrying electrical accumulators (or storage batteries) necessitate
the provision of means for charging these; indeed, it is important that the time
occupied in charging should be reduced as much as possible, since the vehicle
has to be withdrawn from traffic whilst the charging process lasts.
The methods which have been followed hitherto of supplying the storage-
batteries with current through cables, or else of removing the battery and re-
placing it by another one, are somewhat complicated and it is the object of
this invention to substitute for it certain novel means for rendering the charging
more conveniently attainable.
They consist of one, or two, sliding yokes, or what are called "trollies,"
arranged upon the auto-motor vehicle. As the vehicle enters the charging station
these trolleys come in contact with rails, or rods, suspended in a convenient
position at, or near, the station roof, or otherwise secured; so that the moment
the car enters the station it receives current, without there being any occasion
to make special electrical connections for the purpose, the car as soon as charged,
being in readiness to quit the station again, either on the same, or the opposite
side thereof.
Should it be preferred not to use pairs of trolleys, one trolley and also, con-
sequently, a single rail may suffice; but in that case it will be necessary to pro-
vide a special rail at the charging station, along, but insulated from the ground,
and preferably to come in contact with a slide arranged at the bottom of the
vehicle; such additional rail being connected with the other pole of of the
charging machine.
Where this arrangement is adopted it should preferably be carried out in such
a manner that the contact piece, or trolley, as it meets the top-rail, shall be
depressed, and either by means of a cord or by any other suitable mechanism,
release the said sliding device at the bottom of the vehicle, thereby completing
the circuit.

Improvements in Apparatus for Charging Auto-motor Cars.
I, ALFRED GEORGE BROOKES, of 55 & 56, Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
(a communication from abroad by Theodor Stort of Berlin, in the Empire of
Germany, Engineer), and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Motor cars carrying electrical accumulators (or storage batteries) necessitate
the provision of means for charging these, indeed, it is important that the time
occupied in charging should be reduced as much as possible, since the vehicle
has to be withdrawn from traffic whilst the charging process lasts.
The methods which have been followed hitherto of supplying the storage-
batteries with current through cables, or else of removing the battery and re-
placing it by another one, are somewhat complicated and it is the object of
this invention to substitute for it certain novel means for rendering the charging
more conveniently attainable.
In the accompanying drawings, Figs. 1 and 1ª show the side and end elevations
respectively of a motor car with two trolleys upon the auto-motor vehicle;
Figs. 2 and 2" illustrate by side and end elevations respectively a motor car with
but one yoke upon the roof, and the other arranged at the bottom of the vehicle.
The novel means consist of one or two sliding yokes a or what are called
"trolleys," arranged upon the auto-motor vehicle.
As the vehicle enters the charging station, these trolleys a come in contact with
rails, or rods b, suspended in a convenient position at, or near, the station roof,
or otherwise secured, so that the moment the car enters the station it receives
current, without there being any occasion to make special electric connections
for the purpose, the car as soon as charged, being in readiness to quit the station
again, either in the same, or the opposite side thereof.
Should it be preferred not to use pairs of trolleys, one trolley a and also,
consequently, a single rail may suffice; but in that case it will be necessary to
provide a special rail c at the charging station, along, but insulated from the
ground, and preferably to come in contact with a slide d arranged at the bottom
of the vehicle; such additional rail being connected with the other pole of the
charging machine.
Where this arrangement is adopted, it should be preferably carried out in
such a manner that the contact piece, or trolley, as it meets the top-rail shall be
depressed, and either the means of a cord e or by any other suitable mechanism,
release the said sliding device at the bottom of the vehicle, thereby completing
the circuit, this being done automatically by the depression of the contact-piece.
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 :-
1. An automatical charging device for auto-motor vehicle, consisting of two
trolleys or yokes, arranged one besides the other on the top of the car, each of
these trolleys etc. coming in contact with one of two sliding bars connected
with the poles of the electric generator, substantially as described.
2. A modification of the device first claimed having but one trolley on the top
of the car, the other being arranged on the bottom of the car and mechanically
connected with the first said trolley by means of cord or other suitable device,

page_text: in such a manner, that a depression of the first one produces contact of the
second one with a special rail, thereby closing the circuit of the charging
generator, substantially as described.
