page_text: I, WILLIAM HUMPHREY WHEATLEY, of the Firm of Wheatley & Mackenzie,
Engineers and Patent Agents, of 40, Chancery Lane, in the County of London,
England, do hereby declare the nature of this invention, (a communication to
me from Leon Rosenfeld, Constantin Zelenay, and Julien Dulait, all of Charleroi,
in the Kingdom of Belgium), to be as follows:-
The system of electro-dynamic propulsion which forms the object of this
invention is based on the fundamental idea according to which a conductor of
any length whatever would be excited so as to discharge a propelling magnetic
force parallel to itself to actuate an armature maintained at a suitable distance
from the said conductor which has no other relation to the armature than that
created by the action of the propulsive force.
Thus in carrying this principle into effect the inducing wire and the induced
coil of a monophase or polyphase alternating current motor, the elements being
rectilinear or plane in place of curvilinear as in the rotary armature condition,
the inducing wire constitutes the conductor discharging a propulsive force acting
in the manner indicated on the induced coil or armature.
In fact the development in rectilinear elements is equivalent to a motor with
a radius of infinite length in which the rotary motor action determined in
motors with limited radius by the displacements limited in consequence of the
induced current, is transformed into a single rectilinear tangential force dis-
charged by the conductor in conformity with and actuating the induced coil
of which it is totally independent in regard to the source of electric energy.
Thus in establishing a rectilinear conductor of any length whatever, com-
prising the elements of an inductor of an alternating current motor and in
causing it to act on an armature comprising the elements of the corresponding
induced coil and carried at suitable distance from the conductor by a vehicle
in constant relation to the same, we create, in principle the system of electro-
dynamic propulsion capable of being fed at will by alternating monophase and
polyphase currents which forms the object of our invention.
The principle of the novel system of electric propulsion being thus established,
it is obvious that the same is capable of application to all similar industrial
undertakings, such as railways, tramways, overhead traction lifts etc. in which
it has the novel advantage that the motors at present used as propellers are
replaced by a simple induced coil, there being a complete dispensing with
every means for transmission of energy from the conductor to the propeller.
such as overhead or underground trollies, electro-magnetic or electro-mechanical
contrivances and so on.

page_text: Of course the arrangement and working of the system vary according to
the nature of each application of the principle and the constructional differences
in regard thereto may be considerable without any departure from the scope
of the invention.
In the application of the principle to trams and tramways, for example, the
inducing wire run out in a right line may be placed along any suitable line
of the way, and it consists either in a solid body of iron, or of joined thin
plates of sheet iron, insulated from another in accordance with the principles
of proper electrical construction. This metallic body is notched with transverse
holes which may be placed perpendicularly or obliquely in relation to the
surface of the sheet iron plates and in these holes or notches which run right
through the conductor are wound the coils, the wires of which are traversed by
the current coming from the source of electric energy thus creating magnetic
fields parallel to the conductors.
The corresponding induced coil or propeller, likewise run out in a right line
is composed of a series of sections each of which is constructed in all points
conformably to the conductor, that is to say, each carrying a certain number
of induced coils wound in a manner identical to the winding adopted in the
induced coil of a three phase motor with rotary field and each of these sections
with coils constituting the propeller, and carried by the vehicle in such a
manner that the faces placed opposite to those of the conductor are maintained
at the smallest possible distance therefrom.
This section of the propeller is suspended to the vehicle by any supple or
articulated cable or incans of connection. The section heads of the propeller
carry rollers between the arms of pivoted forks adapted to be moved together by
means of a rod.
The forks serve to transmit to the vehicle the effort of traction produced by
the action of the conductor on the propeller, as to regulate the value of the
effort in raising or lowering the suspended propellers. Thus if the rollers on
the propellers are displaced to the extent desired with the aid of the rod by
one or other arm of the forks the vehicle is actuated with greater or less force
by the propeller.
pro-
The starting and stopping of the vehicle may be effected in any suitable
manner, either by putting the induced sections of the propeller into communica-
tion through the medium of a rheo. tat or by raising or lowering the
peller with the assistance of a lever arrangement or again by the com-
bination of these two means, or finally by any other coupling in series or
in parallel of induced coils regulated by any suitable controllers.
In the present instance it is supposed that the conductor runs continuously
along the rail road, but it might in the other instances occupy only 50% of the
length of the road in alternately interrupted parts the supposed gaps being
cleared by the active or acquired momentum of the vehicle.
We would add that it is obvious that the conductors may be fed in series
or in parallel either from the same source or by interposed feeders.
Further, we would remark that the present invention can be advantageously
applied in the working of large railway systems, the alternating currents specially
admitting of the transport of energy at a long distance, and besides in con-
nection with town systems it has the advantage of eliminating the causes of
inductions in telephonic or other systems in the same way, as it gets entirely rid
of any electrolysis of the apparatus for distributing gas, water and the like.

page_text: I, WILLIAM HUMPHREY WHEATLEY, of the Firm of Wheatley & Mackenzie,
Engineers and Patent Agents, of 40, Chancery Lane, in the County of London,
England, do hereby declare the nature of this invention, (a communication to
me from Leon Rosenfeld, Constantin Zelenay, and Julien Dulait, all of Charleroi,
in the Kingdom of Belgium), and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement : -
The system of electro-dynamic propulsion, which forms the object of this
invention is based on the fundamental idea according to which a conductor of
any length whatever would be excited so as to discharge a propelling magnetic
force parallel to itself to actuate an armature maintained at a suitable distance
from the said conductor which has no other relation to the armature than that
created by the action of the propulsive force.
Thus, in carrying this principle into effect, the inducing wire and the induced
coil of a monophase or polyphase alternating current motor, the elements being
rectilinear or plane, in place of curvilinear as in the rotary armature condition,
the inducing wire constitutes the conductor discharging a propulsive force acting
in the manner indicated on the induced coil or armature.
In fact the development in rectilinear elements is equivalent to a motor with
a radius of infinite length in which the rotary motor action determined in
motors with limited radius by the displacements limited in consequence of the
induced current, is transformed into a single rectilinear tangential force dis-
charged by the conductor in conformity with and actuating the induced coil
of which it is totally independent in regard to the source of electric energy.
Thus in establishing a rectilinear conductor of any length whatever com-
prising the elements of an inductor of an alternating current motor and in
causing it to act on an armature comprising the elements of the corresponding
induced coil and carried at suitable distance from the conductor by a vehicle
in constant relation to the same, I create in principle, the system of electro-
dynamic propulsion capable of being "fed" at will by alternating monophase and
polyphase currents which forms the object of my invention.
The principle of the novel system of electric propulsion being thus established,
it is obvious that the same is capable of application to all similar industrial
undertakings. such as railways, tramways, overhead traction lifts, etc. in which
it has the novel advantage that the motors at present used as propellers are
replaced by a simple induced coil there being a complete dispensing with
every means for transmission of energy from the conductor to the propeller,
such as overhead or underground trollies, electro-magnetic or electro-mechanical
contrivances and so on.
Of course the arrangement and working of the system vary according to
the nature of each application of the principle and the constructional differences
in regard thereto may be considerable without any departure from the scope
of the invention.
In order to more precisely explain the idea of the system of propulsion thus
described in general terms, I will describe the application of the principle to a
tramway with reference to the accompanying drawing.
Fig. 1 is a side elevation one half in section.
Fig. 2 a transverse section.

page_text: The inducing wire run out in a right line, may be placed along any suitable
line of the way, in the present instance, it is placed mid-way between the rails
and consists either in a solid body of iron or of joined thin plates of sheet iron
insulated from one another in accordance with the principles of proper electrical
construction. This metallic body is notched with transverse holes I I I which
may be placed perpendicularly or obliquely in relation to the surface of the
sheet iron plates and in these holes or notches which run right through the
conductor as shown in Fig. 2 are wound the coils, the wires of which are
traversed by the current coming from the source of electric energy thus creating
magnetic fields parallel to the conductors. As in this instance there is a three
phase current "feed" the three wires belonging to this kind of current are wound
in coils in the manner indicated by way of example in Fig. 3 showing the
three wires in heavy black lines, fine black lines and dotted lines respectively.
The corresponding induced coil or propeller likewise run out in a right line
is composed of a series of sections each of which is constructed in all points
conformably to the conductor, that is to say, each carrying a certain number
of induced coils wound in a manner identical to the winding adopted in the
induced coil of a three phase motor with rotary field and each of these sections
with coils constituting the propeller and carried by the vehicle in such a
manner that the faces placed opposite to those of the conductor are maintained
at the smallest possible distance therefrom (Fig. 1 and 2).
This section of the propeller is suspended to the vehicle by supple cables c
or by any other supple or articulated means of connection. The section heads of
the propeller carry rollers G between the arms of forks F brought into relation
one with the other by means of the rod Teach being pivoted at a point 0.
These forks serve to transmit to the vehicle the effort of traction produced
by the action of the conductor on the propeller as well as to regulate the value
of this effort in raising or lowering the suspended propellers. Thus if the
rollers G are displaced to the extent desired with the aid of the rod T by one or
other arm of the forks, the vehicle is actuated with greater or less force by the
propeller.
The starting and stopping of the vehicle may be effected in any suitable manner
either by putting the induced sections of the propeller into communication
through the medium of a rheostat as illustrated in Fig. 1 or by raising or
lowering the propeller with the assistance of a lever arrangement as shown in
Fig. 1 or again by the combination of these two means, or finally by any other
coupling in series or in parallel of induced coils regulated by any suitable
controllers.
In the present instance it is supposed that the conductor runs continuously
along the rail road, but it might in the other instances occupy only 50% of the
length of the road in alternately interrupted parts the supposed gaps being
cleared by the active or acquired momentum of the vehicle.
I would add that it is obvious that the conductors may be "fed" in series or
in parallel either from the same source or by interposed feeders.
Further I would remark that the present invention can be advantageously
applied in the working of large railway systems, the alternating currents specially
admitting of the transport of energy at a long distance and besides in con-
nection with town systems it has the advantage of eliminating the causes of
inductions in telephonic or other systems in the same way as it gets entirely rid
of any electrolysis of the apparatus for distributing gas, water, and so on.
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;-
-
1. System of electro-dynamic propulsion, distinguished by the maintenance
at appropriate distance from a conductor discharging a tangential propulsive force
under the influence of electric energy, of an armature or induced coil susceptible

page_text: of being actuated along the length of the conductor by the sole propulsive force
mentioned and without the intervention of any other connection.
2. A mode of carrying out the system of propulsion indicated under Claim 1,
distinguished by the forming in rectilinear elements of the induction and induced
systems of a monophase or polyphase alternating current motor and by constitut-
ing the said inductor a conductor and attaching the induced system or propeller to
a vehicle keeping it at an appropriate distance from the conductor.
3. In the system of propulsion indicated under Claim 2 a form of construction
of the propeller or induced system distinguished by composing the same of
several consecutive induced sections controlled simultaneously by the person in
charge of the vehicle.
4. The improved electro-dynamic system of propulsion substantially as
described with reference to the drawings.
