16 Claims. (Cl. 155-180) The `main objects of this invention are: Very much wider than the inner arm so that the First, to provide an improved spring structure ledge is substantially spaced from the upper which, although made of comparatively light maedge of the border frame. The border frame is terial, is'rvery rigid and capable of withstanding preferably continuous, being formed of sections :'5 severe usage, and thereby well adapted for trucks, joined together or of one piece bent to suitable 5 buses andthe like. shape and dimensions and the ends joined.

The clamping tongues 2| corresponding to the clamping tongues I I are clamped against the inner side of this upholstery retaining strip I9, the parts being otherwise as shown in detail in Figs. 2 and 3.
In the embodiment shown in Fig. 5 the border frame 22 is provided with a straight inturned flange 23 providing a support for the upholstery and on which the upholstery is clamped by the U-shaped strip 24, which also constitutes a binding member or wear plate, although in this embodiment the cross strips 6 extend below theA plane of the rim. The cross strips are provided with retaining tongues 2| for the strip.
In the embodiment shown in Fig. 6 the upper edge of the border frame 25 is folded downwardly at 2G upon the vertical portion and thence bent inwardly to provide a horizontal portion 2l overhanging the supporting ledge 5. The edge of this horizontal portion is bent downwardly at 28 so that after the clamping strip is inserted this downturned portion 28 may be crimped or bent at intervals, as at 29, to retain the upholstery clamping strip.
My improved spring structure is exceedingly rigid, the cross pieces serving to effectively brace and support the rim. The rim is economical in material and easily formed. ^rThe parts may be very quickly and easily assembled, even by unskilled workmen.
I have not attempted to illustrate or describe other modifications or adaptations which I contemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt the same as may be desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
