The elliptic spring 2 of the'ypresent embodi
inent may beconsidered .ascomprising a-pair of
semi-elliptic springs 6 and 1; each of which in
volves plates 8 held together by vspring bands ‘9 $
and the extreme ends of eaclrhank of plates
resting on end‘blocks ID, as is usual.
‘present ‘embodiment; the fourhelical springs _3
are shown‘as singlecoil ‘springs,- although I do
not wish to be limited to this disclosure. Both 50
the "upperyspring plate 4 and the lower spring
plate 5 arewsubstantially H-shaped inyplan and
each formed of two identical‘ pieces ll ‘disposed
on opposite sides‘ of‘the elliptic, springjz, Each
piecelrmaybe formed ?at. of, the “desired shape 5.5
and then folded on the center of a rectangular
opening which, after folding, provides a wide
notch i2 to hold the corresponding spring band 9.
To assemble, the top and bottom half plates
are connected together through the two helical
springs of the half group, as by means of bolts
l3 passing through corresponding apertures M
in said plates. In order to allow for movement
of the upper plates toward the lower upon com
10 pression of the springs'without buckling the as
sociatedbolts, each plate is desirably embossed
toward the companion plate, as indicated at l5,
so that the bolt used is much shorter than the
normal distance between the upper and lower
15 plates, the embossments leaving space to allow
for movement of the bolt without buckling upon
compression of the springs, as well as providing
centering, means or collars for the associated
helical springs. In order to provide for inter
20 locking the nest of springs with respect to the
side frame and associated bolster, each plate
desirably has embossments or nibs l6 adapted to
?t in corresponding pockets in the frame, spring
plank or bolster and each plate also desirably has
25 a tapering embossment |'| adapting it to nest
over the reinforcing corrugation corresponding
with that designated by. the reference character
l3a of the Reissue Patent No..18,266 previously
referred to.
Although, of course, such a corru
30 gation I1 is not needed for cooperation with the
bolster, yet in order to make theupper and lower
plates interchangeable, said plates are desirably
correspondingly formed.
To apply the nest of springs to the frame, the
35 helical springs and their plates may be put in
place'?rst and pushed to the side up the double
truss incline of the frame. ‘The elliptic spring
may then be put in place on the frame, or spring
plank if used, and the coil springs and‘ their
40 plates slid down into position. As the notches |2
- in the. plates embrace the elliptic spring bands,
their locating plugs or nibs I6 will enter the
corresponding holes or pockets in the frame or
the upper spring band 9a and side portions 24
which straddle the elliptic spring and terminate
in normally horizontal apertured portions 25
which underlie the plates 2| and receive the re
taining bolts l3a thereof. Like the lower plate
IS, the upper plate 22 is desirably formed with
centering plugs Hi“.
In the present embodiment, the nest is desira
bly assembled in place on the lower spring plate
l8, and theupper elliptic spring plate 22 applied, 10
after which, the bolts. l3a may be secured in
place, as illustrated. The upper helical plates
2| are applied over the end portions 25 of the
plate 22, said plates 2|, of course, being formed
with spring collars 20, embossments 26 to cor- l5
respond with the embossments of the lower spring
plate for a similar purpose, although not neces~
sarily similar in size, and notches 21 to interlock
with the centering plugs I 6a of the upper plate
22. '
The vspring plates 2|b andv 22b shown in Fig
ure 9 correspond with the plates 2| and 22 of
Figure 8, except that the centering plugs I?b are
formed on the plates 2| b instead of on the plate
22, and the plate 22b is notched to interlock with 25
said plugs, as indicated at 28. It will also be seen
that the embossment l5b of the’ plate 2|b corre
sponds more nearly with the embossment |5e of
the lower plate.
It will be understood that when the nest of 30
springs just‘ described is in place in a side frame
and serves for support of a bolster so that the
elliptic spring 2a is compressed to a height cor
responding with that of the ellipticisprings 3“,
