Improvements in or relating to Electrically Propelled Motor Cars.
I, FREDERIC WILLIAM DICKINSON, of St. Ann's Works, 46, Cookridge Street,
Leeds, in the County of York, Electrical Engineer, do hereby declare the nature
of this invention to be as follows:-
:-
This invention relates to motor cars propelled by electricity, and its object
is to so construct and arrange the yokes or framework supporting the electro
motors that it may be employed for connecting or coupling two of them together
instead of fixing them on framework, separately and connected by slings to the
body of the car or to other framework as hitherto. By the means herein
described there is a great saving of space and consequent gain of power in the
motors.
According to this invention the yokes or framework, hereafter termed the yokes,
may be made in any number of parts, in any suitable form and shape, and of
metal, for example, say, of cast or wrought iron or steel. The yokes are provided
on its upper and lower surfaces with a number of projections, say, two, or the
projection on each side of the yoke may be prolonged to permit of the electro-
magnets, or portions thereof when made in more parts than one,-of each electro

to the body of the car by suitable prolongations either directly or to framework
interposed between them. The sides of the yokes may be connected together by
a cross-bar fixed to the same between the two electro-motors. In the cross-bars a
central bearing may be formed for the armature spindles which may be separated
from each other at or about the centre of the bearing to permit of the indepen-
dent rotation of each armature. Or the inner ends of each armature spindle may
be arranged to support each other.
The other parts of the electro motors, such as the armatures, coils, brushes, and
like parts, may be of ordinary construction and the electro-motors geared either
directly or through any suitable arrangement of gear wheels and shafts, with or
without chains or their equivalents, to the wheels of the car in any convenient
and ordinary manner.
By the above described means the electro motors may be arranged in much less
space than hitherto, and greater efficiency of working ensured.

Improvements in or relating to Electrically Propelled Motor Cars.
1, FREDERIC WILLIAM DICKINSON, of St. Ann's Works, 46, Cookridge Street,
Leeds, in the County of York, Electrical Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement: -
This invention relates to motor cars propelled by electricity, and its object is
to so construct and arrange the yokes or framework supporting the electro-motors
that they may be employed for connecting or coupling two of them (the motors)
together, instead of fixing them on framework separately, and they are connected
by slings to the body of the car, or to other framework as hitherto. By the
means herein described there is a great saving of space, and consequently a gain
of power in that the motors may thereby be increased in size.
In the drawings hereunto annexed:-
Fig. 1 is an elevation in outline of a motor car with these improvements applied.
Fig. 2 is an enlarged part elevation of the yokes or framework with one
electric motor shown in position.
Fig. 3 an enlarged end elevation of same.
Fig. 4 an enlarged plan.
A are the yokes or framework hereafter termed the yokes, which are made of
metal, say of cast or wrought iron or steel, and in any number of parts bolted
or otherwise secured together, and in any suitable form or shape. Thus for
example, instead of making the yokes A in one piece as shown in the drawings,
the projections B between the electric motors may be made separately and bolted
to the yokes A. The yokes A are provided on their upper or lower surfaces or
at their centres, shown in the drawings on the upper surface, with a number of
projections B, which are prolonged as shown, to permit of the electro-magnets C,
-or portions thereof when said magnets are made in more parts than one,―of
each electro-motor being fixed thereto in any suitable and convenient manner,
such as for example, say, by the bolts D.
The projections B are connected either directly to the body E of the car by
suitable prolongations or by hangers F, as shown at Fig. 1, or to a framework
interposed between the yokes A and the body of the car. In the drawings_the
projections B are shown attached directly to the body of the car by hangers F.
The sides or prolongations B of the yokes A are connected together by a cross
bar G fixed to the same between the two electro-motors. In the cross bar G
is formed a central bearing H for the armature spindles I. The central bearing H
as shown is really in the form of a double bearing with a central space J (Fig. 4)
between them, in order to provide for the said spindles I being separated from
each other at or about the centre of the space J so as to permit of the indepen-
lent rotation of each armature which may be found necessary, say. in turning
corners. Or the inner ends of each armature spindle may be arranged to support
each other by letting the end of one spindle into the end of the other spindle.
The prolongations B are also connected together at a suitable distance from
their outer ends by means of the stays or cross bars K in which are also formed
bearings L for the outer ends of the armature spindles I.
The outer ends of each pair of prolongations B are connected together by the
bridge piece M which is bolted thereto and terminates in a bearing N for an
intermediate shaft 0 (parallel with the armature spindle) which is armed at its
outer end with a sprocket wheel P and at its rear end with a spur wheel Q
arranged to gear with a spur pinion R mounted and fixed on the armature
spindle I as shown.

page_text: The other parts of the electro-motor, such as the armatures S, coils T, commu-
tators U,the armatures and commutators being mounted upon the spindles I
as shown, brushes (not shown) may be of the usual and ordinary construction.
The electro-motors may be geared to the rear wheel of the car, as shown at
Fig. 1, by means of the sprocket wheels V mounted and fixed on the axle of the
car wheel to which motion is transmitted from the sprocket wheel P on the
intermediate shaft O through chains W. Or any other suitable arrangement such
as gear wheels and shaft may be employed for connecting the parts together, or
the electro-motors may be geared directly by any convenient means to the axle
of the car.
The car may be of any ordinary and suitable construction mounted upon C
springs X, or not, and provided with steps Y and with a steering appliance
arranged to be fixed to the car say, at Z.
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. The combination and arrangement of parts constituting the improvements
in electrically propelled motor cars substantially as described and illustrated.
2. In apparatus for electrically propelling motor cars the yoke A and parts
connected therewith as and for the purposes described and illustrated.
