jcurrflstances'lof j serviceg This": is' usually a 1 federal yellow, orange, or chome orange. 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.
