The deslgnating character 1s molded at the same time that the entire sectlon is molded and consequently is'integral with the portion 11.1 The rubber constituting the 'up- 7 right portion 11, which'maybe referred to as a leaf, panel or blade, is a high grade resilient' rubber which is capable, whenmade in the thin leaf-like form" illustrated, lof

promptly resuming its upright position foln lowing each flattening by the'bl'ows ofthe traffic and of-so acting continually for a long period of service. 7

If desired the interior of each sectionmay be reinforced by a fabric applied during r v v "manufacture'so as to lie 'near 'ltssurface. 1 ,Such a fabric 12'pre'ferably extends through 7 base 10 and the upright portion 11 as sho'wn in Fig.4. This matter of reinforcement is" one which maybe employed or not as desired.:' 7

Thebase-lO as been smears molded integral with the upright. 11: and islikewise of rubber, reinforced or ?not,l 'as desired. The upper surface of the base is; curved as to provide a thin free edge 'l 'o verwl'rich the traffic will pass without appreciable Jolt and. which will fit more or less closely ir-, j

[As shown, thebase 7 7 10 has a longitudinal dimension .greaterthan that of the panelll. Preferably the panel I is positioned centrally so that the project.-

.ing portions of the'base at each end of are equal; The rear portions of th e d of the base which extend beyond theupright f ,11 are curved downward so as toform a lip 15 similar to thellip 13. Because ofthedifference in the dimensions. of the "base 10 the blade 11,'s'paces 16fare providedfbetween adja'centlpanels 11.. In service the 7 wheels: of a vehicle 'may. often passthrough these spaces without! striking 'jone of the panels. Thus a rgood dealof thetrafii'cfmay pass over the base of the marker:fwithout flattening down the panels and therebythe i by having themarker divided into sections 1 wmin j e cl ifi i ees eas it wheels'fto pass through one ofthe spaces116 will atmostonlyflatten out'one ofi th pg lg [11.

' v Obviously; both the ;,base iand portionsof the sections amay; be considerably varied and stillcome withinthe purview of the invention. Thusfa s shown. in Fig. 2, the uprights 20 of the sections.

This difference is found principally at the; point-where the upper pan'elit l joins the base 45."
