STREET MARKER Filed Oct. 31. 1930 EYQWLLJW VOTAW 5. DUES/N,

Patented Oct. 10, 1933 OFFICE 1,929,809 STREET MARKER Votaw S. Durbin, St. Louis, Mo.

The general object of this invention is to provide a novel street marker for use with a series of similar markers to be anchored in the pavement to provide stop lines for vehicles and to define a safety zone or walk for pedestrains at street intersections.

The leading characteristic or my improved marker is the fact that it is cast from rust-proof metal capable of being burnished to have imparted thereto'a permanent polished surface.

Other features of the invention relate to a novel construction of parts, and use of novel means associated therewith for penetrating the pavement and anchoring the marker therein.

The invention is illustrated in the accompanying drawing in which:

Fig. l is a bottom plan view of the marker;

Fig. 2 is a View in side elevation thereof, one arm of the anchoring member being shown in dotted lines before being bent to its penetrating position; I V

Fig. 3 is a sectional view showing the markerin anchored position on a section of pavement; and

Fig. 4 is a View in side elevation of the marker, viewed from theleft of Fig. 2. I

Referring now to the drawing, the numeral 1 indicates the head of the marker which is circular in shape and provided with an upper convex or rounded surface 2, which the nature of the metal employed enables to be burnished to a high-degree of polish. The head 1. is convex on its under side, as indicated at 3 in Fig. 3, and is provided with a central rectangular keeper 4, cast integral with the head and providing a space 5 between itself and the under side of the head through which a flat bar 6 of flexible metal may be inserted as indicated by the dotted lines in Fig.2. The bar 6 prior to being inserted in the keeper 4 may have one of its ends bent downward at an angle and slightly curved outwardly to form an anchoring I arm 7, Figs- 2 and 3, and after the other end of the bar is inserted beneath keeper 4, as shown by the dotted lines of Fig. 2, it is bent downwardly. in the same manner to form an anchoring arm 8.

Each of the arms 7 and 8 prior to the insertion in the keeper, as described, is cut away at its outer end to form pointed end members 9, Fig. 4, to enable, the arms of the anchoring member to penetrate the material of the pavement under the force of blowsadministered to the head 1'. As stated, each of the arms '7 and 8 is curved outwardly, as indicated at 10 in Fig. 2,. so that whenv driven into the material of the pavement these arms will tend to separate, or to pass into the material of the pavement on diverging lines, so as to offer a greater resistance to any force tending to lift the marker from the pavement than if they weredriven into the pavement in a substantially vertical position. v

Cast integral with the keeper 4 and projecting of the anchoring device.

Application October 31, 1930. Serial No.'492,501 2 Claims. (01. 94-15) downwardly from the under side thereof is a tapered spike 11 having a pointed end l2and which is somewhat longer than the arms 7 and 8 The spike constitutes the main penetrating member of the marker and may be driven. by blows on the head directly into the pavement. The spike 11,-being centrally located enables the marker to be, accurately positioned on the pavement and, when driven home will securely hold the headagainst any force tending to displace it, or move it laterally. The metal from which my improved marker is made is a novel malleable iron metal, which is described and claimed in my pending application Serial Number 477,185, filed August 20, 1930. It is sufficient for the present to say that this metal may becast, is rust-proof, acid-proof, non-magnetic and capable of taking a high chromium fin ish or polish, It may also be of any required deg gree of hardness. The anchoring member or bar 6 and the spike 11 are also made from the same metal; and thus, when anchored in the pavement, my device forms a permanent marker unafiected by weather conditions and consequently immune from rust or disintegration.

' In driving the marker home a suitable bumper, of wood or the like, would be placed on the head of the marker to protect its surface from the blows of the sledge hammer driving it into the pavement. Y

Iclaim: 1. A street markercomprising a cast metal head provided on its under side with an integral keeper spaced from said underside, a spike cast integral with and projecting at right angles to the under side of said keeper and a flexible anchoring memher mountedin said keeper having pointedarms projecting downwardly on opposite sides of said spike.

2. A street marker comprising a con-cavojconvex circular head polished on its convex or upper side, a keeper on and spaced from its under side and a spike projecting from said keeper, said parts being cast as an integral structure, and an anchoring member comprising a fiat bar of flex- 1:05 ible me tal having pointed ends, and positioned centrally in said keeper and bent downwardin the same direction from opposite ends of the keeper to project in diverging lines from opposite sides of said spike. 1
