PROVISIONAL SPECIFICATION,
Improvements in or connected with Auto-motor Road Vehicles.
I, FELIX EDMOND THÉODORE GODARD, of 3, Rue Lantonnet, Paris, in the
Republic of France, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to auto-motor road vehicles and provides a propelling
part which carries the motor or motors, the steering apparatus, the mechanisms
for changing the speed, and the other parts required for operation and which I
will refer to as the bogie.
The device is so arranged that it can be connected with an ordinary vehicle
of any shape such for instance as a brougham, a victoria, an omnibus, a tram-
way car or the like by means of a hollow centre or connection through which
pass the connections for operating the different mechanisms for steering for
changing the speed and for the other operations so that they can be readily
controlled by the driver on the box of the vehicle and can be operated as though
they belonged to an ordinary motor vehicle, in which the motor and the different
apparatus for steering for changing the speed and the other operations, are fixed
to the frame of the vehicle itself.
The brake mechanism is likewise so arranged as to be actuated from the same
place by the driver and so that the brake can be applied to the bogie and to
the vehicle to which it is attached.
The bogie has one driving wheel, provided with a rim of suitable width accord-
ng to the weight to be carried and the power to be transmitted the object of
using one driving wheel being to avoid tripping movements which are liable to
occur in vehicles furnished with two driving wheels, placed either at the front
or at the back of the vehicle.
I obtain great stability by placing the driving wheel at the front and arranging
the brakes to act on the wheels of the vehicle, so that the resistance is always
to the rear of the power, even when travelling down hill.
A very satisfactory stability may even be obtained with the driving wheel of
the bogie arranged behind, providing that the connection of the bogie with the
vehicle drawn thereby be placed very near the vertical line passing through
the axis of the driving wheel. The first mentioned arrangement is how-
ever, preferable. The motor may be worked by steam or petroleum or gas or
by electricity or other suitable motive power.
1 will describe my invention as applied to drawing by an electrically propelled
bogie an ordinary road carriage.
The driving wheel may be actuated by the motor either directly or by the
intermediary of gear wheels and chains in connection with toothed pinions. The
steering wheels are mounted on pivots in the ordinary way and connected by
operating levers and a connecting rod to a shaft actuated by a bent lever, which
is operated by a tubular rod (passing through the aforesaid hollow connection!
and the steering hand wheel by means of a worm and worm wheel.

to the first named tubular rod a crown or rim which carries the brass blocks,
connected to the different electric mechanisms of the vehicle; this crown
rim being adapted to turn in front of a number of contacts serving to vary the
electric connections, and, consequently the speed of the vehicle.
or
The second tubular rod passes to the centre of the hollow connection by which
the vehicle is connected to the bogie. A cylindrical support is arranged con-
centrally to the said hollow connection and is fixed to the vehicle; antifriction
pieces or bearings for antifriction balls are provided on the parts connected to
the bogie and the carriage respectively. A cap screwed on the hollow connec-
tion serves to protect the ball bearings from dust and also to prevent the vehicle
from rising relatively to the bogie in the case of violent concussions or jerks.
The aforesaid tubular rods are connected at their lower ends to the devices
fixed to the bogie, but the upper ends are dismountable and readily adjustable
so as to permit of rapidly changing the vehicle. For this purpose the first
named tubular rod is adapted to fit at its lower part upon a quadrangular pyramid
in connection with the steering mechanism a rod passing through the centre part
of the. said tubular, rod and being screwed into the pyramid its upper part
serving to receive means to retain the operating hand wheel of the rod in.
position.
The second tubular rod is held in position by a collar at the bottom, and
by a ball mechanism at the top.
The brake lever is secured to the vehicle so that by operating either a pedal
or a hand lever the brakes for the wheels of the vehicle and the driving wheel
are operated as desired. The bogie carries all necessary parts such as the reser-
voir containing the water for cooling the motor, and, the cooling apparatus.
furnished with wings for cooling this water and also the mechanical motor or
motors, the generator and the accumulators; the connections between the gene-
rator, the receiver and the accumulators being regulated by the crown or rim
controlled as aforesaid. The driving wheel may if desired be placed behind, and
the steering axle with its two wheels in front. In this device I connect the lever
which actuates the rods coupling the steering wheels to the crank keyed to the
shaft by means of a connecting rod.

Improvements in or connected with Auto-motor Road Vehicles.
I, FELIX EDMOND THÉODORE GODARD, of 3; Rue Lantonnet, Paris, in the
Republic of 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 following statement:-
This invention relates, to auto motor road vehicles and provides a propelling
part which carries the motor or motors, the steering apparatus, the mechanisms
for changing the speed and the other parts required for operation, and which I
will refer to as the bogie.
The device is so arranged that it can be connected with an ordinary vehicle
of any shape, such for instance as a brougham, a victoria, an omnibus, a trami-
way car or the like by means of a hollow stud centre or connection, through

page_text: which pass the connections for operating the different mechanisms for steering,
for changing the speed, and for the other operations, so that they can be readily
controlled by the driver on the box of the vehicle, and can be operated as
though they belonged to an ordinary motor vehicle, in which the motor and
the different apparatus for steering, for changing the speed, and the other
operations, are fixed to the frame of the vehicle itself.
The brake mechanism is likewise so arranged as to be actuated from the same
place by the driver and so that the brake can be applied to the bogie and to
the vehicle to which it is attached.
The bogie has one driving wheel provided with a rim of suitable width accord-
ing to the weight to be carried and the power to be transmitted, the object of
using one driving wheel being to avoid tripping movements which are liable to
occur in vehicles furnished with two driving wheels placed either at the front
or at the back of the vehicle.
I obtain great stability by placing the driving wheel at the front and arrang-
ing the brakes to act on the wheels of the vehicle, so that the resistance is
always to the rear of the power, even when travelling down hill.
A very satisfactory stability may even be obtained with the driving wheel
of the bogie arranged behind, providing that the connection of the bogie with
the vehicle drawn thereby be placed very near the vertical line passing through
the axis of the driving wheel. The first mentioned arrangement is, however.
preferable. The motor may be worked by steam, or petroleum, or gas or by
electricity or other suitable motive power.
I will describe with reference to the accompanying drawings my invention
as applied to drawing, by an electrically propelled bogie, an ordinary road
carriage.
Figure 1 is a longitudinal vertical section of an automotor bogie constructed
and applied according to my invention.
Figure 2 is a horizontal section of the Bogie.
Figure 3 shews, drawn to a larger scale, a vertical section through the hollow
centre or connection.
Figure 4 is a longitudinal vertical section shewing a modified arrangement
of a bogie, and
Figure 5 is a horizontal section thereof.
a is the driving wheel actuated by the motor either directly or by the
intermediary of gear wheels and chains in connection with toothed wheels e, c.
, are the steering wheels, mounted on pivots in the ordinary way and con-
nected, by rods e and a three-armed lever f and link f¹, to a lever arm g keyed
10 a shaft which is actuated by worm gear. Figure 3, operated through the
hollow shaft i by the steering hand wheel Figure 1.
A second hand wheel actuates, a tubular shaft m which carries at its lower
end an appropriate number of contact arms 7, for making contact with brass
blocks on a crown or rim n connected to, but insulated from, the bogie frame,
the said blocks being connected to the different electric mechanisms of the
vehicle. The contact arms are insulated from the hollow shaft m by a collar of
insulating material and can be moved by means of the wheel so as to make.
the electric connections necessary to start, stop or vary the speed of the vehicle
as required.
The tubular shaft m passes through the centre of the hollow connection.
by which the vehicle is connected to the bogie, the said hollow connection being
fixed to the bogie. A cylindrical support is arranged concentrically to the
hollow connection 9 and fixed to the vehicle. s and are bearing pieces for.
anti friction balls between the parts and r. w is a nut, serving to fix the
bearing cone in position and is a cap screwed onto the hollow connection
to protect the ball bearings from dust, and also to prevent the vehicle from
rising relatively to the bogie in the case of violent concussions or jerks.

page_text: The only modification necessary to enable any existing vehicle to be coupled
to the bogie is to provide the vehicle with the piece r.
The tubular shafts and m are connected at their lower ends to the devices
for operating the bogie but they are removeable and readily adjustable, so as
to permit of rapidly changing the vehicle. For this purpose the tubular shaft i
is adapted to fit at its lower end upon the rectangular or equivalently shaped
endy of a worm shaft in connection with the steering mechanism. A rodz
passes longitudinally through the tubular shaft i, and is screwed into the end y
of the said worm shaft the upper end of which rod z is shaped to receive the
operating hand wheel j.
The tubular shaft is held in position by the collar 1 at the lower end and
at the upper part by ball-mechanism.
A brake lever 2 is secured to the vehicle at 4 so that it can be operated either
by the pedal or by the hand lever 5 to actuate the brakes for the wheels of
the vehicle and the driving wheel a. 6 is a reservoir containing water for cool-
ing the motor and 7, Fig. 4, is the cooling apparatus. furnished with wings
for cooling this water.
8 represents the mechanical motor or motors for working, by direct coupling.
the electricity generator 9, and 10 are accumulators. the connections between
the generator 9, the receiver and the accumulators 10 being regulated by the
crown or rim n. and controlled by the hand wheel k.
In the arrangement illustrated by Figures 4 and 5 the driving wheel a of the
bogie is arranged at the rear and the steering axle with its two wheels d d
arranged at the front. In this arrangement the three armed lever f and link fl
which actuates the rods e of the steering wheels d d are connected to the arm
keved to the shaft of the worm gear by means of a connecting rod 11. The
other parts or mechanisms remaining substantially the same as in the arrange-
ment Figures 1 and 2.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The combination in an auto-motor bogie of a driving wheel arranged at
the front end of the bogie and two guiding or steering wheels pivoted on one
and the same axle fixed at the hind part of the bogie; means for connecting
the bogie to the vehicle which it is intended to propel, the said connecting
device being provided with operating handles or hand wheels arranged so as to
admit of the operation of the controlling mechanisms, by the driver or con-
ductor while seated in the vehicle substantially as herein before described.
2. The combination in an auto motor-bogie of a driving wheel arranged at the
hind part of the bogie and two steering wheels pivoted on one and the same
axle fixed to the front part of the bogie, a hollow stud for connecting the
bogie to the vehicle to be propelled and operating mechanism passing through
the hollow stud into the said. vehicle so as to be within reach of the driver,
substantially as herein before described.
3. In a three-wheeled motor bogie such as hereinbefore described the com-
bination of a hollow stud such as q fast on the bogie and passing through a
ring or hollow cone such as fixed to the vehicle to be propelled by the bogie;
anti-friction balls interposed between the parts and t, and two tubes passing
concentrically one within the other through the hollow stud g. one of the said
concentric tubes being connected to the steering mechanism and provided with a
controlling handle or hand wheel the other concentric tube being connected with
mechanism for starting, stopping and controlling the speed of the vehicle, sub-
stantially as hereinbefore described.
4. The combination and arrangement of parts constituting an improved auto-
motor bogie and means for connecting it to the vehicle to be propelled thereby,
