Improvements in Means for Suspending Electric Motors on
Electrically Propelled Vehicles.
I, SIDNEY HOWE SHORT, Electrical Engineer, of 1184, East Madison Avenue,
Cleveland, State of Ohio, U.S.A., 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 means for suspending electric motors
on electrically propelled vehicles, and has for its object to provide an arrange-
ment in which the motor is entirely supported by a frame, which is in part itself
spring-supported, and is entirely separate and distinct from the frame or casing
of the motor itself, and at the same time permits the motor to have a spring
controlled movement of rotation relatively to said frame, thereby doing away
with any injurious contact of the gears and producing an apparatus possessing
other advantageous mechanical features.
An apparatus embodying my invention is shown in the accompanying drawings,
in which,
Fig. 1 is a sectional elevation on the line X X of Fig. 2.
Fig. 2 is a plan view illustrating my invention.
Fig. 3 is a sectional view of a portion of the motor casing and frame showing
details of construction on the line Y Y.
The
Referring to the drawings A is the driven axle of the vehicle on which the
wheels B B are secured in the usual manner. CC are the side bars of the frame of
the vehicle supported by the axles D D in the usual manner. E is a frame,
preferably four-sided, sleeved upon the axle at F and supported from the frame
of the vehicle by the bar G, between which and the frame of the vehicle are
springs H. Buffer springs H¹ are also provided to reduce the shock due to any
upward movement. The frame E is connected with the bar G by the link I.
motor itself is provided with trunnions K K, which, in the form shown, are
integral with the casing L, which constitutes the foundation frame of the motor.
The trunnions K K are journaled in bearings M M in the frame E, so that the
motor has a limited capacity for movement relatively to the frame E. This
capacity is limited and spring-controlled by springs 0 0¹, which engage the upper
and lower sides of lugs P P extending from the motor casing L and preferably
integral therewith. The armature shaft R carries a small gear S, which meshes
with the large gear T in the driven axle, thus transmitting the motion of the
armature to the driven axle. The frame E maintains the motor at a fixed distance
from the driven axle and bodily supports the same. With the cylindrical form
of motor shown, the entire weight of the motor comes dead upon the frame, the
springs 001 serving simply to spring-control any movement of rotation relatively
to the frame.

page_text: Having now particularly described and ascertained the nature of my baid
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In an electrically propelled vehicle the combination of a driven axle, a
supporting frame at one end journaled thereon, and at the other spring-supported
from an independent support, a motor having trunnions journaled in said frame
and springs limiting the movement of said motor relatively to said supporting
frame, substantially as described.

2. In an electrically propelled vehicle the combination of a driven axle, a
supporting frame at one end journaled thereon and at the other spring-supported
from the frame of the vehicle, and a motor having trunnions journaled in said
supporting frame and springs limiting the movement of the motor relatively to
said supporting frame, substantially as described.
3. In an electrically propelled vehicle the combination of a driven axle, a
supporting frame at one end journaled on said axle and having its end remote
from the axle supported from the frame of the vehicle, a spring interposed between
said remote end and the vehicle frame, a motor having trunnions journaled in
said supporting frame and having rearward projections, and springs interposed
between said rearward projections and said supporting frame, 'substantially as
described.

4. In a wheeled vehicle, in combination, a frame journalled upon the driven
axle and spring supported at a distance therefrom from an independent support,
a motor casing attached thereto and supporting ithe armature, said armature con-
nected by gearing to the driven axle, said frame being located with reference to
said motor so that the same can be removed as a whole from one side of said
frame, substantially as described.
