We, WILLIAM LYSTER HOLT, of 17 Parliament Street, Westminster, in the County
of Middlesex, Engineer, and 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 our invention is to so mount electro-motors used for driving vehicles
that the vibration of such vehicles when in motion shall not interfere with the proper
engagement of the gearing employed to transmit motion from the motor to the driving
wheels of the vehicles.
For this purpose we mount the motor so that it is supported by, and consequently
follows the movement of any vibrations to which the axle of the driving wheels may
be subjected, quite independent of the movement of the vehicle in relation to the
driving wheel axle or axles.
The invention may be carried into effect either by making the driving wheel axle
stationary and causing the wheels to revolve thereon, in which case the motor can be
secured to the axle of the driving wheel, or the driving wheel axle may be caused to
rotate with the driving wheels, and also in a frame which carries the motor. In the
latter case the frame for carrying the motor may conveniently form part of or be
secured to the axle boxes of the driving wheels.
Or the motor may be carried by arms mounted on the driving axle (which latter
can turn in such arms), guides being provided to prevent the arms turning on
the axle.
The frame to carry the motor might be supported by two or more of the car axles.
The axles may all be driven from the motor if desired.
The shaft of the motor and the axle of the driving wheels, or the wheels themselves,
are provided with any suitable arrangement of gearing for transmitting motion from
such motors to the driving wheels, and as the vehicle is carried by means of springs
interposed between the driving wheel axle and the under frame of the vehicle, it will
be seen that the engagement of the gearing employed will in no way be effected by
any movement of the vehicle in relation to the driving wheel axle or axles.

Improved Arrangement for Applying Electro-motors to Vehicles.
We, WILLIAM LYSTER HOLT, of 17 Parliament Street, Westminster, in the County
of Middlesex, Engineer, and MORITZ IMMISCH, of 199 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 our invention is to so mount electro-motors used for driving vehicles
that the vibration of such vehicles when in motion shall not interfere with the proper
engagement of the gearing employed to transmit motion from the motor to the
driving wheels of the vehicles.
For this purpose we mount the motor so that it is supported by, and consequently
follows the movement of any vibrations to which the axle of the driving wheels may
be subjected, quite independent of the movement of the vehicle in relation to the
driving wheel axle or axles.
The invention may be carried into effect either by making the driving wheel axle
stationary and causing the wheels to revolve thereon, in which case the motor can be
secured to the axle of the driving wheels, or the driving wheel axle may be caused
to rotate with the driving wheels, and also in a frame which carries the motor. In
the latter case the frame for carrying the motor may conveniently form part of or be
secured to the axle boxes of the driving wheels.
Or the motor may be carried by arms mounted on the driving axle (which latter
can turn in such arms), guides being provided to prevent the arms turning on
the axle.
The frame to carry the motor might be supported by two or more of the car axles.
The axles may all be driven from the motor if desired.
The shaft of the motor and the axle of the driving wheels, or the wheels themselves,
are provided with any suitable arrangement of gearing for transmitting motion from
such motors to the driving wheels, and as the vehicle is carried by means of springs
interposed between the driving wheel axle and the under frame of the vehicle, it will
be seen that the engagement of the gearing employed will in no way be affected by
any movement of the vehicle in relation to the driving wheel axle or axles.
In order that our invention may be fully understood we will now proceed to
describe same by aid of the accompanying drawings, in all of which the same letters
are employed to indicate similar parts wherever possible.
Fig. is a half transverse section and Fig. 2 a longitudinal section showing one
method of carrying the invention into effect. In these Figs. A is a stationary axle,
shown square in section (see Fig. 2), but it may be of any other suitable section, and
on it the wheels W are free to revolve. If the space above the axle, between it and
the flooring of the vehicle, is limited (as would be the case where wheels of small
diameter are employed), the axle A may be bent or cranked to give more headrooni
for the motor M.

page_text: Attached to the inside face of each of the wheels W is a large toothed wheel T, T
and mounted on the axle A, and secured thereto is the motor M provided with a
spindle S sufficiently long to allow of a pinion wheel P being keyed on each end to
engage with the large toothed wheels T.
Brackets B B are provided and fixed to the axle A for the purpose of carrying
the motor spindle S. The body of the car C is quite independent of all these parts
and is mounted in the usual way with horns N to allow of vertical movement. The
portions of the axle A, in the guide blocks H are square to take the thrust when
the motor M is put in motion.
Figs. 3 and 4 show another method of carrying the invention into effect, where it
will be seen that the motor M is carried on an independent frame F. This framing
is secured to or made a portion of the axle boxes X X and is prevented from turning
when the motor is in motion not only by the axle boxes XX which are of the usual
type and fitted with hornslides N, but by the guides G G which take the thrust, and
as they run loose in their sockets K K formed on framing F they allow of any vertical
movement of the body of the car C without affecting such independent motor
framing F. The large toothed wheel T in this instance is keyed to a revolving axle A
which runs in the ordinary way in axle boxes X X.
The motor spindle S and pinion wheel P are shown in this instance directly over
the axle, but they may be placed at any convenient angle thereto. Sun and planet or
other gearing as shown in Figs. 1 and 2 may of course be substituted for the gearing
shown in these Figs.
Figs. 5 and 6 show a method of running with the motor M placed vertically, the
gearing employed in this instance being that known as worm and wheel. The
motor M is secured to an independent frame F F which in its turn is made rigid with
the axle boxes X X as before; and to the driving wheel axle A (which in this case
revolves), is keyed a worm wheel w w which engages with the worm W on the motor
spindle, the body of the car being carried in the ordinary way on springs.
Another method is shown in Figs. 7 and 8 by which the motor M is carried on a
revolving axle A without the intervention of framing. The motor is provided at the
foot with brasses or bearings in which the axle A revolves. The gearing is shown
the same as in Fig. 1 but to take the thrust a pin I is secured to the top of the
motor M and enters a gland or socket g which is bolted to the bottom of the sole plate
or flooring of the carriage C.
The body of the car Cas in all the other instances may be carried in the usual way
on springs V V with the ordinary axle boxes X and hornblocks N.
In Fig. 9 which is a half side elevation and half longitudinal section a method is
shown of carrying tlie motor M on more than one axle, and utilizing all the wheels as
driving wheels. An iron framing F of any suitable shape and section runs from axle
to axle and is carried on brackets K to which it is secured, and in which the axles A
revolve.
The motor M is mounted on this frame F and the spindle S in this case is extended,
and on each end carries a worm W which gears with worm wheels w w on the axles.
Brackets B are provided as before for carrying the motor spindle S and a thrust
block t is introduced to take the strain.
The axle boxes X are quite independent of and distinct from the brackets K. They
are ordinary axle boxes and are here shown carried outside the driving wheels D.
Figs. 10, 11 and 12 are respectively a longitudinal section, transverse section and
plan of another method of carrying the invention into effect. The motor M in this
instance is shown as being carried on two angle irons L which run from axle box to
axle box X, the motor spindle S and the driving axles A being fitted with V-shaped
pullies and the motion transmitted from the smaller or motor spindle pulley to
the axle pulley and thus to the driving wheels D themselves by means of ropes,
chains or belts.
As the body of the car C is in all the cases above described carried by means of
springs interposed between the driving wheel axle A and the under framing of the
vehicle itself it will be readily seen that any movement of the body will be quite

page_text: independent of the movements of the axles and also the gearing which is fixed thereto,
and in consequence, the engagement of the gearing will not in the least degree be
affected by any jolts or jerks to which the vehicle may be subjected.
The spindle S of the motor and the axles A of the driving wheels, or the wheels
themselves, may be provided with any suitable arrangement of gearing for trans-
mitting motion from such motor to the driving wheels, (as for instance in Fig. 5
where the motor M is placed vertically, bevel gearing may be conveniently substituted
for that shown), those shown in the drawings illustrating some of the arrangements
which may be employed, and which may be varied according to requirements and the
desire of the constructor.
Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed, we declare that what we claim is :-
In the application of electro-motors to the driving of vehicles.
1. The improved method of carrying motors by supporting same on the axle or
axles of the vehicle or to parts connected therewith capable of moving independently
of and in relation to the body of such vehicle, for the purpose of preventing the
vibrations imparted to the vehicle when in motion from interfering with the proper
engagement of the gearing employed to transmit motion from the motor to the driving
wheels, all substantially as specified.
2. Fixing the motor directly to the axle or axles of the vehicle and mounting the
driving wheels so that they are free to revolve on such axle or axles, substantially as
described and shown in Figs. 1 and 2 of the accompanying drawings.
3. Supporting the motor in a frame carried by the axle or axles of the vehicle,
which latter can revolve in such frame, and preventing the latter turning on the axle
or axles by means of pins or guides carried by the vehicle entering sockets formed
on the frame, substantially as described and shown in Figs. 3 and 4 of the
accompanying drawings.
4. Carrying the motor in a vertical position on a frame supported by the axle or
axles of the vehicle, substantially as described and shown in Figs. 5 and 6 of the
accompanying drawings.
5. Carrying the motor on the axle, which is capable of revolving in the motor
frame, and preventing it turning on the axle by means of a pin on the motor entering
a socket or gland on the vehicle, substantially as described and shown in Figs. 7 and 8
of the accompanying drawings.
6. Carrying the motor on a frame supported by brackets mounted on two or more
of the axles of the vehicle substantially as described and shown in Fig. of the
accompanying drawings.
7. Carrying the motor on a frame supported on two or more of the axles of the
vehicle, substantially as described and shown in Figs. 10, 11 and 12 of the
accompanying drawings.
