PROVISIONAL SPECIFICATION.
Improvements in Carriages or Vehicles for Use on Common Roads.
I FRANK KING of 4 Great Winchester Street, in the City of London, Electrical
Engineer do hereby declare the nature of my invention to be as follows:-
My invention relates to carriages or vehicles for use on common roads wherein
the means of propulsion are combined with the carriage or vehicle itself and more
particularly is intended for use with such carriages or vehicles as are provided with
what are known as pneumatic wheels or wheels provided with pneumatic tyres.
According to my invention I use for propelling the carriage or vehicle two motor
apparatus of any suitable kind each such motor apparatus being attached
respectively to each of the two portions or lengths of a divided axle each portion
or length being supported at one side by a wheel and at the other side by a bearing
or journal which may be common to both portions or lengths of the axle and which
supports the axle at or about the centre line of the carriage or vehicle.
The two portions or lengths of the axle are capable of being rotated indepen-
dently of each other by the independent action of the motor apparatus attached
thereto so that when the carriage or vehicle is required to turn the wheel attached
to the portion or length of the axle on the outer side of the carriage or vehicle must
travel over a longer distance than that travelled over by the other wheel and this
can be done without skidding or dragging the wheels over the ground owing to the
independence of the two portions or lengths of the axle the one from the other.
Dated this 10th day of October 1893.

COMPLETE SPECIFICATION.
Improvements in Carriages or Vehicles for Use on Common Roads.
I FRANK KING of 4 Geat Winchester Street in the City of London, Electrical
Engineer do hereby declare the nature of my invention and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement :-
My invention relates to carriages or vehicles for use on common roads wherein
the means of propulsion are combined with the carriage or vehicle itself and more
particularly is intended for use with such carriages or vehicles as are provided with
what are known as pneumatic wheels or wheels provided with pueumatic tyres.
According to my invention I use for propelling the carriage or vehicle two motor
apparatus of any suitable kind each such motor apparatus being attached respec-
tively to each of the two portions or lengths of a divided axle each portion or
length being supported at one side by a wheel and at the other side by a bearing or
journal which may be common to both portions or lengths of the axle and which
supports the axle at or about the centre line of the carriage or vehicle.
The two portions or lengths of the axle are capable of being rotated indepen-
dently of each other by the independent action of the motor apparatus attached
thereto so that when the carriage or vehicle is required to turn the wheel attached
to the portion or length of the axle on the outer side of the carriage or vehicle
must travel over a longer distance than that travelled over by the other wheel and

page_text: this can be done without skidding or dragging the wheels over the ground owing to
the independence of the two portions or lengths of the axle the one from the other.
In order that my invention and the manner in which it may be performed may
be clearly understood I refer to the accompanying drawings which illustrate so
much of an electrically driven vehicle as is necessary to illustrate the application
of
my invention thereto.
Figure 1 is a sectional plan and Figure 2 is a sectional elevation. Figure 3 is a
section of the axles separately.
66
a a are wheels which may be of the kind known as pneumatic" wheels or wheels
provided with pneumatic tyres or they may be wheels of any other kind but as the.
object of the invention is to prevent skidding the said invention is especially
advantageous with pneumatic wheels or wheels with pneumatic tyres.
61 63 are the axles carrying the said wheels there being an axle for each wheel.
The said axles are supported in the frame c and their inner ends meet but are
separated at the centre of the said frame.
d is a sectional view of the bearing (shewn on one side only but there will of
course be one on the other side also). These carry the vehicle to be propelled and
support the outer ends of the axles.
It
indicate a form of gearing commonly in use, by means of which, the power
for driving is applied from the electric motors f₁f through the worm gear g.
will be seen that the motors flf being entirely distinct may be driven at different
rates; and thus while continuing to drive their respective wheels enable the said
wheels to pass over the ground in turning corners without the skidding of either
wheel.
For the better support of the divided or double axles at their inner ends I may
construct them of tubular form as shewn in Figure 3 and fit a solid or tubular axle
in the aperture so as to allow the outer axles to run independently of each other as
herein before described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In carriages or vehicles for use on common roads an axle formed in two lengths
and each carrying a wheel and each being capable of being driven independently
of the other substantially as and for the purposes herein before described.
