In'the ‘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 2 2,187,151 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“, the ears 25 of the top retaining plate break con- 35 tact with the under sides of the helical or spec tacle plates 2|.
