Application filed J'uly' 26, 1927; Serial No. 208,526.

This invention relates to improvements intraflic markers such as are placed at street intersections to designate areas for the movement of traffic or the presence of restricted An object of my invention is to provide an improved .tratfic marker having a constr'uc tion which permits its being readily imbedded in thepavement of a street or roadway without interfering in any manner with the passage of traiiic over it. p

' Another object of my invention is to provide a traffic marker having a construction which preventsits becoming dislodged from I the pavement of a street or roadway after act as means for preventing its dislodgment when once it has been driven into the payement of a street or roadway.

Other ob 'ects or advantages will b'eapparent from the following description considered in .conjunction with the accompanying drawing forming a part of this application, in which Figure l is a perspective view of a traffic marker embodying my invention;

Fig. 2 is a sectional view of the same taken on the line 2-2 of Fig. 1; and

Fig. 3 is a top plan view, showing the traflic marker reduced in size.

Referring to the drawing, the numeral 1 represents a top plate lying in a generally flat plane, having its four corners bent downwardly as at 2, to form four triangular shaped legs 3. Each of the legs 3-is positioned atapproximately right angles to the top plate 1. and each terminates at a sharp pointed end 4 which permits the said legs to be readily driven into the pavement of a street or roadway.

The top plate. 1 and the legs 3 are bent upwardly and outwardly to form outwardly extending raised arts or outwardl pressed corr' I itions 5, wiiich extend at right angles to each other across the top plate, intersect at the center of'the top plate and terminate at the pointed ends 4 of the legs 3. The top plate 1 is provided with a'plurality of circular shaped raised parts 6 which serve the purpose of making the top of the traiiic marker more visible as well as symmetrically roughened to assist in the passage of trafiic over it The outwardly pressed corrugations 5, when the legs 3 are driven into the pavement of a street or roadway, forma key .with the pavement as the ke way, thereby preventing the trafiic marker rom becoming in any manner dislodged or" jarred from a secure and proper position within the pavement. Upon the traffic marker being driven into the pavement by the striking of the top plate 1, the material of the pavement becomes lodged inside the corrugations 5 of the said top plate, thereby further assisting in maintaining the marker in an embedded position in the pavement.

As shown in Fig. 2 in dotted lines, the legs 3 may be made to swing outwardly within. the pavement upon striking the corrugations 5 at a point thereon where they assume a downward position along the legs 3. The shape and positionof the corrugations with reference to the position and general shape of the legs and top plate, cause the legs to be swung outwardly against the pavement material when the said corrugations are struck as described, thereby preventfirml lie traffic marker from moving upwardly ing t after it has once become so imbedded in the pavement. Y

'My invention is susceptible of embodiment in forms other than those illustrated in the drawing, so for this reason it is to. be understood that all modifications or adaptations which fall within'the scope of the appended claim are to be included therein.

Having described my inven ion, what I,

claim 1s:

A traflic marker comprising a top plate, a plurality of legs extending downwardly from the top plate, a pluralitycf outwardly pressed corrugations located in the top plate and. the legs, each of which said corrugations commences at the end of one of the legs and extends upwardly along the said leg and across the top plate, which said corrugations when struck on the corru ations' at a point where the legs and top ate meet swing the legs outwardly so the egs become, embedded in a material.
