Improvements in Means for Driving Motor Carriages.
I, Jons VAUGHAN-SHERRIN of 28 Victoria Street Westminster London
Electrical Engineer do hereby declare the nature of this invention to be as
follows:-
According to these improvements I provide on a car or carriage an oil engine
with oil supply cistern and connect thereto by preference on the same shaft a
dynamo which is electrically connected with an accumulator battery and thence
with an electric motor on the road wheel axle. In connection with the dynamo
and the oil supply cock I provide a switch, also a switch for the oil engine igniter
current and a switch for starting the electric motor, also a switch for reversing
the motor current. The consequence of this arrangement is such that, supposing
the accumulator is charged current is switched on to the dynamo so as to start it
and therewith also the oil engine on or connected to the dynamo shaft; the igniter
current being put on, the oil engine will now work the dynamo and the current
produced by the latter will pass to the accumulator. It will be understood that
charging action goes on whether the carriage is running or stopping. The electric
motor can now be started and by means of suitable resistance appliance at any
desired speed. The oil engine and dynamo are fixed on a separate spring frame
so as not to communicate vibrations or shocks to the carriage. Instead of an oil
engine I may use any other engine worked by gas or vapour.

Improvements in Means for Driving Motor Carriages.
1, JOHN VACCHAN-SHERRIN of 28 Victoria Street Westminster, London,
Electrical 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 following statement:-
According to these improvements I provide on a car or carriage an oil engine
with oil supply cistern, and connect to that engine and by preference on the same
shaft a dynamo which is electrically connected with an accumulator battery and
thence with an electric motor on the road wheel axle. In connection with the
dynamo and the oil supply cock I provide a switch, also a switch for the oil engine
igniter current, and a switch for starting the electric motor, also a switch for
reversing the motor current.

page_text: Fig. 1 of the drawings is a side view and Fig. 2 a plan of a motor carriage with
driving gear of this kind. A is the cylinder of an oil engine and B the crank
shaft thereof. C is the armature of a dynamo mounted on the shaft B and D an
accumulator battery receiving current therefrom. E is the armature of an electro-
motor hung upon the carriage axle F upon which also the driving wheels G are
fixed; this motor receives current from the accumulator battery. The fore-
carriage with steering gear may be of any suitable construction. H is a switch
for the igniter current, I a starting switch for admitting current from the
accumulator to the dynamo. K is a switch for admitting current from the
accumulator to the motor E, and L is a switch for reversing the current.
The consequence of this arrangement is such that, supposing the accumulator
is charged, current therefrom is by the switch H admitted to the dynamo C so as
to start it and therewith also the oil engine A connected to the same shaft B; the
igniter current being put on by the switch H, the oil engine will now work the
dynamo, and the current produced by the latter will pass to the accumulator.
It will be understood that the charging action goes on whether the carriage is
running or stopping. The Electric motor can now be started by the switch K
and by means of suitable resistance appliance at any desired speed. The oil engine
and the dynamo are fixed on a separate frame M which by rubber block springs
or other springs is suspended from the body frame N of the carriage so that the
vibrations of the oil engine are not communicated to the frame N. Instead of an
oil engine I may use any other engine worked by gas or vapour.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:-
In a motor carriage the application and use of an oil engine or other explosive
engine in combination with a dynamo on or connected to the same shaft and by
preference arranged on a frame elastically connected to the carriage body frame,
an accumulator battery normally receiving current from the dynamo, an electric
motor on the road wheel axle, and suitable switches for electrically connecting the
dynamo, the accumulator and the electric motor, substantially as set forth.
Dated this 27th day of August 1897.
