The present invention relates to a spring sus
pension for motor vehicles and embodies, more
specifically, an improved connection between the
frame and spring of a vehicle, in which connec
suitable clamp mechanism I4, all in accordance
with standard practice.
As viewed in Figure 1, the left-hand end of thev
spring assembly is adapted to be mounted upon

to cushion the action of the spring with respect
to the frame.

with a mounting flange I6 and secured to the
frame I0 by means of rivets l1. In a similar fash
ion the right-hand end of the spring is received
within a housing I8 formed with a flange I9,
which is secured to the frame Ill by means of
rivets 28.
More particularly, the invention relates to a
spring suspension of the above character, where
in the spring is formed of two sections, a main
and a helper spring, and wherein means are
Referring speciñcallyto Figures 2, 3, 4, and 5,

the structure of the housing I8 will be described
more specifically. From these views, it will be
seen that the housing is formed vn'th a lower
mounting face 2l which is open downwardly and
adapted to be closed by a cover 22 secured thereto
by means of bolts 23. Cutaway portions 24 and
same time providing an effective anchor connec
tion for the main spring, additional means being
provided for accommodating suitable action of the
helper spring.
A further object of the invention is to provide
an improved cushion connection between the

frame and spring of the motor vehicle, wherein
elongation of the spring may be accommodated 20 ‘opposite sides of the housing.

The top of the housing is formed with a flat
mounting surface 28 upon which a second cover
29 is secured by means of bolts 30. The top of
the housing 28 is also formed with a slot 3l, the
under-surface of the top portion 28 being re
cessed at 32 to receive a wear plate 33. Wear
plate 33 is also formed with a slot 34 which reg
isters with the slot 3l.
The adjacent end of the main spring Il is
