TRAFFIC GUIDE.

Application led May 18, 1923. Serial No. 639,982.

To all 4whom t may concern: v

Be it known that I, THOMAS G. CRETNEY,

a citizen of the United States, residing at Madison, in the county of Dane and State of 5 IVisconsin, have invented certain new and useful Improvements in Traffic Guides, of

which the following is aspecification.

My invention relates to a practical means for directing traffic at street junctions and l intersections; and the objects o f my invention are, first, to provide a durable metal guide to be placed in, and secured to the center of a street; second, to have words of instruction cast on the guide in embossed letters; third, to so locate the guides adjacent the street intersections that by obeying the instruction Keep to right will regulate the movementI of traffic and prevent accidents. I attain these objects by the mechanism shown in the accompanying drawing in which- Fig. l, is a diagram of a street intersection with four guides in position;

Fig. 2, is a plan of the guide;

Fig. 3, is a front elevation;

Fig. 4, is a vertical section on line A-B Fig. 2, and a portion of concrete street.

Similar numerals refer to similar parts throughout the several views.

The guide 1 is a hollow spherical segment of metal with a plurality of depending calks 2 spaced around the chord or bottom, said .calks depend at right angles to the base on their right hand edges but diverge from the point on the back and inside surfaces giving support to the point. Through the center of the guide a hole 3 is located, and pockets 4 in alignment and directly over the calks are provided to facilitate packing for transpordo tation. 0n the upper surface of the guide,

opposite each other are cast in embossed letters the words Keer) to right. A bolt 5 with a head 6 and hook 7, is provided for securing the guide to the surface of a street at the desired location. To install my guides, first drill a hole large enough to admit the hook end of the bolt-a distance downward into the street at the desired location, then drill a small hole for each of the calks, place'the guide with the letters Keep to right trans- Libferselv of the street, and fill the hollow under thueJ guide, through the hole 3 with a thin mixture of cement and water and insert the bolt forcing it downward until the head 6 rests upon the guide, and when the cement hardens the guide will be securely located. In the diagram Fig. l, it will be seen that a car C making a right hand turn from street I) will enter into the trafiic on the right side of street E at C1, and going straight through will reach C2, also if making a left hand turn will be in line with the traffic on street E at C3, eliminating confusion at such places, by obeying the instruction Keep to right. My guide will also be useful if placed at intervals in the center of paved country roads to keep traffic separated at a safe distance.

Having thus described my invention, I claim: l

In a trafiic guide, a hollow convexed segment of metal with a plurality of depending calks around the bottom thereof, said calks at right angles to the base on their face or right hand edge and diverging to their junction with the base, pockets over each of the calks, a hole through the top of the guide for disposing an attaching bolt and through which cement may be poured, in combination with the words Keep to right cast in embossed letters on opposite sidesy of the guide, for directing traffic 1n the proper course.

In testlmony whereof I afhx my signature 1n the presence of two subscribing witnesses.
