Description
G. D. MYERS TRAFFIC MARKER Aug. 1, 1933.
Filed Nov. 4, 1950 Patented Aug, 1, 1933 PATENT OFFICE 1,920,582 TRAFFIC MARKER George Dalton Myers, Cincinnati, Ohio, assignor to The Edwards Manufacturing Company, Cincinnati, Ohio, a Corporation of Ohio Application November 4, 1930 :Serial No. 493,346
2 Claims.
This traffic marker has been designed with an object of overcoming structural weakness as well as the corrosive tendency of markers of the same general type disclosed herein, with a reduction in the cost of production and consequent sale price of such a marker.
These and other objects are attained in the marker described in the following specification and illustrated in the accompanying drawing, in which:
Fig. l is a top plan view of a marker embodying my invention.
Fig. 2 is an inverted plan view of my improved marker.
Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 3.
In traffic markers of the type here disclosed, there has been developed a great demand for vast quantities of them, based on their notable success for the purposes of marking trafficlanes, safety zones, street crossings and the like.
Resulting from this much competition has grown, with a consequent tendency to cause a constantly lowering sale price. This, in turn, forces the manufacturer to devise ways and means of lowering his manufacturing costs without sacrificing certain of the advantageous features of which such markers are capable. For example, it is essential that the marker shall possess noncorrosive characteristics in order that its head or plate shall remain bright from the polishing action given it by tramc. Such materials as are capable of such a finish usually have to be a hard and expensive metal or alloy, which will withstand trafiic strains, or they have to be so materially softer than this that the strains and blows from trafiic will result in cracked off fastening pins and consequent destruction of the marker. The hard noncorrosive metals are very expensive, thus rendering their use prohibitive, while the soft metals are not practicable for use because of structural weakness, although their cost is within explanation of the problem of costs, sale price, wear resisting characteristics,strength and corrosive action, it is obvious that no relatively cheap and strong base metal such as iron or cold rolled steel can be used without having to resort to an expensive plating operation which, at once, renders the step impractical.
In the marker I will now describe, I have rendered all the stated difficulties of small importance. In this marker, which has a plate 4 to occupy the pavement surface, and a pin 5 to fasten the marker to the pavement, I use a metal,
very strong and well blows and strains of heavy traffic without break- 75 reason. In View of the foregoing or one of its many and inexpensive alloys, as the metal from which substantially the entire marker is, constructed. In fact the plate 4, and the pin 5 are entirely constructed of this metal with the exception of a pin core or reeniorcement 6 which is cast into the pin at the time the marker is cast into shape. The reenforcement 6 is or may be off steel which, for purposes of simplicity, may be of an ordinary screw threaded element such as a screw, machine screw, cap screw, set screw, or 65 other adaptable element which will become fixedly embedded in the noncorrosive metal against loosening or displacement therefrom; In this manner the binding of the metals of the reenforcement 6 and of the pin 5 and plate 4, will assure of the plate and pin being strengthened at, in, or about the region of their union by element 6, thus causing the marker to be adapted to withstand the age.
Another feature of my invention is that the lower end of the reenforcement 6 is extended to form the point of the marker pin 5, so that a hard and sharp pointed end is provided to enable the marker to be fastened to the pavement by driving its pin into the pavement material. This is essential in the case of some pavements, the material of which would blunt, break off, or disintegrate the material of the market pin were it 85 not provided with the hard metal point.
A feature of value is the manner in which I have provided the under face of the'plate of my trafiic marker with radial and concentric ribs 7 and 8 respectively, which cooperate in becoming embedded in the pavement and thereby prevent movement of the marker..
Having thus described claim is:
1. A traffic marker comprising a metal plate, and a metal pin extending from the plate, said pin consisting of two portions, one of said portions lying within the other portion, forming the end of the pin and extending into the plate, the metal of the other portion of the pin and plate being continuous.
2. A traffic marker comprising a plate, and a pin extending from the plate, said pin consisting of a hard metal pointed core and metal encasing the core except at its point, the encasing metal my invention what I of the pin and the plate being cast as a unit.
