I, MORITZ IMMISCH, of 119 Torriano Avenue, Camden Town, London, in the County
of Middlesex, Electrician, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to simplify the application of electro-motors to
vehicles, and which may readily be adapted to existing vehicles.
For this purpose I employ motors which are wound to give a good efficiency with
a comparatively slow speed, so as to dispense with any counter-shafting. Its spur
pinion is mounted on the shaft of the motor, and gears directly with a spur wheel
fixed on the axle of the driving wheel or wheels.
In order that the vertical movement due to vibrations when the vehicle is in motion,
may not disturb the distance between the centres of the pinion and wheel, I mount
the motor in the following manner :-
The motor is placed transversely to the vehicle, and the back of its frame is
suspended by a link to the body of the vehicle itself, while its front end is formed
with a sleeve or sleeves to surround and be supported by the axle of the driving wheel
or wheels. A part of this sleeve is preferably made removable to allow the motor to
be easily detached.
The point of suspension of the back of the motor is preferably as nearly as possible
at the centre of the distance between the axles of the carriage, so that any rocking
motion should have as little effect as possible in disturbing the position of the motor
in relation to the vehicle.
This arrangement affords facilities for examining and repairing the motor, when
necessary, by simply detaching it from its rear point of suspension, and then swinging
it upwards round the axle of the driving wheel into the vehicle, the floor of which is
made removable for this purpose.

page_text: Improved Arrangement for Applying Electro-motors to Vehicles.
I, MORITZ IMMISCH, of 119 Torriano Avenue, Camden Town, London, in the County
of Middlesex, Electrician, 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:
The object of this invention is to simplify the application of electro-motors to
vehicles, and the system may readily be adapted to existing vehicles.
For this purpose I may employ motors which are wound to give a good efficiency
with a comparatively slow speed, so as to dispense with any counter-shafting. In
this case a spur pinion is mounted on the shaft of the motor, and gears (either directly
or by means of a chain) with a spur wheel fixed on the axle of the driving wheel or
wheels.
My invention may also be applied to motors running at high speeds, suitable
reducing gear being interposed between the motor spindle and the axle of the driving
wheel or wheels.
In the accompanying drawings Fig. 1 is a plan view showing the position the
motor occupies in relation to the driving axle of the vehicle, the transmission being
direct from the motor spindle to such axle.
Fig. 2 is a similar view showing the same arrangement when reducing gear is
employed between the motor spindle and the driving axle of the vehicle.
Figs. 3, 4, and 5, are detail views showing the mode of suspending the motor, and
also the method of driving.
In Fig. 1 the motor shaft or spindle A is provided with a pinion B gearing directly
with wheel C on the driving axle D of the vehicle. Instead of such spur gearing the
transmission from pinion B to wheel C may be by a chain E as shown in Fig. 4; or
pulleys, with a belt or rope passing over same, may be substituted for the wheel and
pinion.
In Fig. 2 the transmission from motor shaft A to the axle D is by means of
reducing gear, illustrated in Figs. 3, 4 and 5, which Figs. show that shaft A carries a
pinion F, gearing with a set of idle wheels G carried by a frame H, to which the
pinion B is secured, the idle wheels G also gearing with a fixed internal toothed
wheel I (shown secured to the bearing A' of motor shaft A). By properly pro-
portioning the diameters of pinion F, idle wheels G, and fixed wheel I, the speed
transmitted to pinion B, from motor shaft A, may be reduced to any required extent.
Pinion B may (as in the previous arrangement) either gear with wheel C on axle D,
or a chain E passing over both may be employed, as shown in Fig. 4.
In order that the vertical movement, due to vibrations when the vehicle is in motion,
may not disturb the distance between the centres of the pinion B and wheel C, Í
mount the motor in the following manner :-
The motor is placed transversely to the vehicle, and the back of its frame is
suspended by a link J to the body of the vehicle, while its front end is formed with a

page_text: sleeve or sleeves K. (two being shown in Figs. 1 and 2) surrounding the axle D of
the vehicle. The sleeve or sleeves is or are provided with a removable cap K³, to
allow the motor to be easily detached. It will be seen that by this arrangement any
vertical movement, due to vibrations when the vehicle is in motion, will not disturb
the distance between the centres of pinion B and wheel C (either when they gear
directly or through the chain E), as the sleeves K surrounding axle D keep such
distance always the same in spite of any vertical movement, while the flexible
connection formed by the link J allows the motor frame to move in relation to the
vehicle itself, so that the efficient gearing of such pinion and wheel will in no way be
affected.
The point of suspension J' of the back of the motor, is preferably as nearly as
possible at the centre of the distance between the axles of the carriage, so that any
rocking motion should have as little effect as possible in disturbing the position of the
motor in relation to the vehicle itself.
In vehicles which are mounted on bogie trucks the point of suspension J¹ will
consist of a hook and eye connection as shown, or it may be a ball and socket joint,
so as to permit the motor frame to turn with the bogie truck in relation to the body
of the vehicle when the latter is running on a curve.
This arrangement affords facilities for examining and repairing the motor, when
necessary, by simply detaching it from its rear point of suspension J', and then
swinging it upwards round the axle D of the driving wheel into the vehicle, the floor
of which is made removable for this purpose.
I wish to be understood that I lay no claim to the mode of transmitting motion
from the motor shaft A to the axle D of the driving wheels of the vehicle.
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 :-
Suspending electro-motors to vehicles by means of a link J attached to the undor-
side of the body of the vehicle, and a sleeve or sleeves K. surrounding the axle of the
driving wheel or wheels of such vehicle, substantially as and for the purpose specified.
