Improvements in and relating to Electrically Propelled Vehicles,
especially adapted for High Rates of Speed.
I, RICHARD RICHARDSON HUTCHINSON of No. 8 Lombard Court, in the City
of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in the construction of vehicles, and
apparatus in connection therewith, for attaining high rates of speed upon a suitable
track, the motive power being derived from an electrical current, the source of
which may be a storage battery or accumulator carried by the vehicle, or a
generating station or stations, said current in this case being conveyed to the
vehicle by means of fixed conductors, according to any of the well known methods
therefor.
In carrying my invention into effect, I employ a long car or carriage of circular,
elliptical or curvelinear cross section, each end being pointed for the purpose of
reducing the surface resistance when travelling at a high rate of speed. Said car
or carriage is mounted upon two or more bogie trucks or carriages, having pre-
ferably three sets of wheels upon each. Said wheels are provided with deep
flanges or other equivalent device to-maintain the vehicle upon the track. Upon
the axle of each pair of wheels I mount the armature of an electric motor, and
arrange a compound field magnet in such a manner that a magnetic field embraces
each armature, upon the same limb or limbs, the coils being wound between said
fields, thus constituting a bipolar, tripolar, or quadrupolar motor, according to the
number of armatures and axles placed upon each bogie carriage. In order to
preserve the armatures from stripping or other injury from contact with the fields
occasioned by inequalities of the track, or oscillation due to the high speed, I
attach bracket bearings to the polar faces, supporting the axles, which really form
the armature spindles, inside the wheels. Any movement lateral or vertical due to
oscillation or jolting is therefore directly transmitted to the field magnet, and these
are practically supported and carried by said brackets: The bearing journals
preferably outside the wheels, and are carried in axle boxes within the side frames
of the bogie carriage, or horse plates attached thereto, suitable springs being used
to afford the proper degree of free motions. I also prefer to use transverse springs,
between the bogie carriages and the body of the vehicle. In cases in which I
derive the current of electricity from an accumulator or storage battery, I prefer
to carry the cells in a portable tray or box, suspended below the body of the
vehicle between the bogie carriages, and I may employ the method of and means
for re-charging, or renewing the accumulator described in the Specification of
Letters Patent No. 15277 A.D. 1885, or any other feasible method of or means for
the same purpose.
In cases in which I derive the current from a stationary
generating plant, I provide means for collecting from the rails or an independent
conductor or conductors.
חיוני
I do not confine myself to the employment of any special type or description of
armature, but in every case employ a field magnet, with two, three or more polar
surfaces in the continuous length thereof. I may cause the leading and trailing
wheels of the end bogie carriages to be magnetised by winding, attaching electro
magnets, or by induction, the object thereof being to procure greater adhesion to
the rails and minimise the risk of derailment. I also make use of electric or other
brakes, electric lighting and heating appliances, and suitable means for governing
or controlling the speed and power of the motors, collectively or independently,

page_text: also providing a mechanical or electrical device upon each motor for reversing the
direction of motion.
In order to facilitate the passage of curves or the like at the high rate of speed
which I propose to employ, I provide one or more flexible, or semi-flexible joints in
the body of the vehicle, these being strongly made of metal or the like, and in such
a manner as not to effect the rigidity of said vehicle, or to impair the strength
thereof.
I prefer to construct the frames of the bogie carriages, the accumulator trays,
and every projecting part of the vehicle and the fittings therefor of curvilinear
form, to reduce the atmospheric or wind resistance to a minimum, and I may build
the body of the vehicle of bent wood, with transverse grain to ensure lightness and
strength.

COMPLETE SPECIFICATION.
Improvements in and relating to Electrically Propelled Vehicles.
especially adapted for High Rates of Speed.
I, RICHARD RICHARDSON HUTCHINSON of No. 8 Lombard Court, in the City
of Loudon, 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:—
My invention relates to improvements in the construction of vehicles, and
apparatus in connection therewith, for attaining high rates of speed upon a suitable
track, the motive power being derived from an electrical current, the source of
which may be a storage battery or accumulator carried by the vehicle or a generating
station or stations, said current in this case being conveyed to the vehicle by means
of fixed conductors, according to any of the well known methods therefor.
In order that my invention may be clearly understood, I have appended the
accompanying sheet of drawings, in which
Figure 1 represents a view of a complete motor vehicle.
Figure 2 a plan view of the motor trolley or bogie, and Figure 3 an end elevation
thereof.
In carrying my invention into effect I employ a long car or carriage, A Figure 1,
which may be of circular, elliptical or curvilinear cross section being pointed at the
ends for the purpose of reducing the surface resistance to the air when travelling
at a high rate of speed. Said car or carriage is mounted upon two or more bogie
carriages or trucks a a¹ having preferably three sets of wheels upon each. Said
wheels are provided with deep flanges or other equivalent device to maintain the
vehicle upon the track. Upon the axle B Figures 2 & 3 of cach pair of wheels W
1 mount the armature V of an electric motor, and arrange a compound field magnet
or magnets M M M" in such a manner that these fields embrace each armature
upon the same limb or limbs the coils S. S₁ S" Su being wound between and
beyond each field, thus constituting a multipolar or compound motor. In order to
preserve the armatures from stripping or other injury, as for instance by contact
with the field magnets occasioned by inequalities of the track, or oscillation due to
the high rate of speed, I attach bracket bearings D D D D D D
Figures 2 and 3 to the polar or magnet faces M M M", said bearings supporting
or carrying the axles B B B", which really form the armature spindles inside the
wheels W. Any movement laterally or vertically due to jolting is thus directly
transmitted to the field magnet or magnets, M and these are practically supported
and carried by said brackets D. The bearing journals C, CC are preferably
placed outside the wheels, and are carried in the axle boxes within the side frames
of the bogic carriage or in the horn plates attached thereto, suitable springs being

page_text: provided to allow of a proper freedom of motion. I also prefer to use transverse
springs between the bogie carriages and the body of the vehicle.
In cases in which I derive the necessary current of electricity from an
accumulator or storage battery, I prefer to carry the cells in a portable tray, box,
or the like, G Figure 1 suspended below the body of the vehicle between the
bogie carriages; and I may employ the method of and means for re-charging or
renewing the accumulator described in the Specification of Letters Patent
No. 15277 A.D. 1885, or any other feasible method of or means for the same
purpose, but I do not confine myself to any one particular method.
In cases in which I derive the current from stationary generating plant, I provide
means for collecting the same from the rails or from an independent conductor or
conductors in any way which may seem the most desirable.
I do not confine myself to any special type or description of armature but in
every case I employ a field magnet or magnets with two three or more polar
surfaces in the continuous length thereof.
In some cases I may cause the leading and trailing wheels of the end bogie
carriages a and a Figure 1 to be magnetised by winding; attaching electro-
magnets or by induction, the object thereof being to procure greater adhesion to
the rails, and to minimise the risk of derailment. I also make use of electric or
other brakes, electric lighting and heating appliances; and I provide suitable
means for governing or controlling the speed and power of the motors either
collectively or independently, and a mechanical or electrical device upon each
motor for reversing the direction of motion.
In order to facilitate the passing of curves or the like at the high rate of speed
which I propose to employ, I may provide one or more flexible or semi-flexible
joints in the body of each carriage in such a manner as not to affect the rigidity of
said carriages or to impair the strength thereof, said carriages being strongly
constructed of metal or the like.
I prefer to construct the frames of the bogie carriages, the accumulator trays or
boxes, and every projecting part of the vehicle and the fittings therefor of a
curvilinear form or design, in order to reduce the atmospheric or wind resistance to
a minimum, and I may build the body of the vehicle of bent wood with transverse
grain to ensure lightness and strength with curved bow or projecting windows bb
Figure 1 if desirable.
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 :-
First. In an electromotive carriage the combination of a curvilinear outline with
compound electro-motors directly connnected to and with the driving axles, sub-
stantially as herein described and shewn.
Second. In an electromotive carriage the employment of compound field magnets
with consecutive poles wound to embrace two or more armatures substantially as
herein described and shewn.
Third. In an electromotive carriage the means for supporting the armatures, to
maintain concentric rotary motion without touching the polar surfaces, substantially
as herein described and shewn by the drawings.
