Improvements in and relating to Motor Suspension for Electric
Auto-motor Vehicles:
I, ALFRED GEORGE BROOKES, of 55 and 56, Chancery Lane, in the County of
London, Chartered Patent Agent (a communication by Theodor Stort, of Berlin,
in the Empire of Germany, Engineer), do hereby declare the nature of this
invention to be as follows:-
In self propelled motor vehicles it is advisable, in order to make the driven
hind wheels independent of each other, to make provision for each wheel to be
operated by a special motor. Now with a view to obtaining a simplified con-
struction the motors should be arranged in juxta-position and co-axially and
joined together by a rigid intermediate piece. "Or a rigid connection of the two
motors may be effected by means of one motor-case or magnet-case common to
both, the effect thereby obtained, in regard to suspension, being the same as that
which would be produced by a single-motor arrangement. The outer journal-
necks of the motors should be turned true (in a lathe &c.) and the entire structure
supported in a frame, adapted to oscillate about the driven axle, in such a manner
that the motors may jointly revolve about their own axis, though such rotation on
their part will be resisted by springs, designed at the same time to limit the range
of oscillation of the frame about the rear axle.
By such means the construction will be materially simplified, while the number
of structural parts, springs &c., may remain the same as in the case of single-
motor suspension.

Improvements in and relating to Motor Suspension for Electric
Auto-motor Vehicles.
I, ALFRED GEORGE BROOKES, of 55 and 56, Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
(a communication by Theodor Stort, of Berlin, in the Empire of Germany,
Engineer) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:―
In selfpropelled motor vehicles it is advisable, in order to make the driven

operated by a special motor. Now with a view of obtaining a simplified construc
tion, the motors should be arranged in juxtaposition and coaxially and joined
together by a rigid intermediate piece. Or a rigid connection of the two motors
may be effected by means of one motor-case or magnet-case common to both; the
effect hereby obtained, in regard to suspension being the same as that which could
be produced by single motor arrangement.
The invention is shown in the accompanying drawings.
Figs. 1 and 1 illustrate by a side view and plan respectively the arrangement
with only two gear-wheels and are an elevation and a plan of it.
Figs. 2 and 2 illustrate by side view and plan respectively a modification with
intermediate wheels.
The outer journal necks of the motors a should be turned true in a lathe etc.
and the entire structure in a frame c, adapted to oscillate about the driven axle d,
in such a manner that the motors may jointly revolve about their own axis, though
such rotation on their part will be resisted by springs g, designed at the same time
to limit the range of oscillation of the frame c about the rear axle, and that by
means of the legs f which are pressed against the said springs.
By such means, the construction will be materially simplified, while the number
of structural parts, springs etc. may remain the same as in the case of single motor
suspension.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
-
For selfpropelled vehicles the arrangement of suspension means consisting of
a frame oscillating about the driving, and supporting the motors and intermediate
wheels, the motor-cases having an independent rotary motion about their axle,
limited by springs and legs, substantially as described.
