Improvements in Means for Propelling Vehicles by Electricity.
We JOSEPH KINCAID Civil Engineer of 11 Great George Street and EDWARD
MANVILLE Electrical Engineer of 68 Victoria Street and JOHN EDWARD WALLER
Civil Engineer of 11 Great George Street all in the City of Westminster do hereby
declare the nature of this Invention to be as follows:-
In cases where the working current is desired to be conducted to the motor of the
vehicle through conductors laid along the line of route it frequently occurs that
difficulties arise owing to their being places at which the continuance of such
conductors is objectionable or impossible. In cases where the current is supplied
from storage batteries alone the expense of maintenance and inconvenience of
removal for recharging and replacing are very great. The object of this Invention
is to overcome these objections.
According to this Invention we provide accumulators in connection with the
vehicle and these are so connected with the working conductors along the route that
whilst the said conductors supply current to the motor they can also be made to
supply current to charge the accumulators so that the said accumulators can be used
to supply current to propel the vehicle either in substitution for or in addition to
current derived from the conductors on the route. Thus for instance where the
conductors can no longer be continued the accumulators will be connected so as to
supply energy to the motor or where the current is supplied by a series circuit the
accumulators may be used to provide power additional to that supplied thereto from
the working conductor.
The combination described is applicable in cases where the current is supplied to
the vehicles either in multiple arc or in series circuit.

COMPLETE SPECIFICATION.
Improvements in Means for Propelling Vehicles by Electricity.
We, JOSEPH KINCAID Civil Engineer of 11 Great George Street and EDWARD
MANVILLE Electrical Engineer of 68 Victoria Street and JOHN EDWARD WALLER
Civil Engineer of 11 Great George Street all in the City of Westminster 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:
In cases where in propelling vehicles by electricity the working current is desired
to be conducted to the motor of the vehicle through conductors laid along the line of
route of the vehicle it frequently occurs that difficulties arise owing to there being
places at which the continuance of such conductors is objectionable or practically
impossible. In cases where the electric current is supplied from accumulators or
secondary batteries alone the expense of maintenance and inconvenience of removal for
recharging and replacing are very great. The object of this Invention is to over-
come these objections.
According to this Invention we provide accumulators or secondary batteries in
connection with or carried by the vehicle and these accumulators or secondary
batteries we so electrically connect with the working conductors along the route that
whilst the said conductors supply current to the motor they can also be made to

page_text: supply current to charge the accumulators or secondary batteries so that the said
accumulators or secondary batteries can be used to supply current to propel the
vehicle either in substitution for or in addition to current derived from the conductors
on the route. Thus for instance where the conductors are no longer continued the
accumulators or secondary batteries according to our Invention are connected so as to
supply energy to the motor or where the current is supplied by a series circuit the
accumulators or secondary batteries may be used to provide power additional to that
supplied thereto from the working conductor.
The combination described is applicable in cases where the current is supplied to
the vehicles either in multiple arc or in series circuit.
The electrical connection of the accumulators or secondary batteries with the
conductors along the route may be effected in any suitable way either by means of
the same contacts as those which convey current from the said conductors to the
motor or by separate contacts. There are also provided conductors from the
accumulators or secondary batteries to the motor and a switch or switches is or are
provided in the conductors from the conductors on the route to the accumulators or
secondary batteries and from the accumulators or secondary batteries to the motor so
that the accumulators or secondary batteries can be stored or caused to supply current
to the motors as desired.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
In electrically propelled vehicles deriving energy from conductors along the line
of route the provision of accumulators or secondary batteries carried by the said
vehicles or in a vehicle or part attached thereto and provided with conductors and
switches so as to allow of their being charged or stored from the conductors along the
line of route and of supplying when necessary energy to the motors of the vehicles
either in addition to or in substitution for the current derived from the conductors
along the line of route.
