UNITED STATES WILLIAM F. STELLNER, -OF,IDA1\IVILLE,ILLINOIS.-

TRAFFIC stench.

Application filed October 12, 19 22. Serial No. 594,021.

To all whom it may concern Be it known that I, WILLIAM F. STELLNER, a citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in Trafiic Signals, of which the following is a specification.

This invention relates to traflic signals and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a signal of the character stated which is of simple and durable structure and which may be easily and quickly set up or removed from a roadway or street as desired.

lVhile the device is primarily intended as a traflic signal it may be used to advantage for other purposes as for instance Safety first sign, Quiet zone, Hospital, Schoolhouse Dan er Drive slow No arka a 7 3 p lng, Street names, and the like.

l/Vhen used as a trafiic dlrecting or controllin si n the si nal is rovlded with the usual words Stop and Go.

The slgnal structure comprlses a socket member which is permanently planted in the circuit portion of a street or roadway. shaft or standard is slidably received in the socket member. This shaft is provided with a collar which closes the upper end of the socket member. A traffic signal casing A is revolubly mounted on the upper end of the shaft and is provided with angnlarly disposed side surfaces upon one of which appears the word Stop and upon an adjacent surface appears the word Go when the signal is used for controlling the movement of trafiic. In use the officer or director stands at the side of the signal and faces in the direction from which the vehicles are approaching. With one hand he turns the signal casing to bring an intended legend of instruction to view to the occupant of an approaching vehicle and he may with the other hand indicate the direction in which the vehicle is to proceed.

In the accompanying drawing Figure 1 is a side elevation of the traffic signal with parts broken away and parts in section.

Figure 2 is a horizontal sectional view of the signal casing, and Figure 3 1s a fragmentary vertical sectional view of the same.

As illustrated in the accompanying drawings, the signal structure comprises a socket member 1 which is closed at the bottom and open at. the top. The socket member is adapted to be planted or mounted in the circuit portion of a street or roadway, in any suitable manner, and as indicated in Figure 1 of the drawing, with its open end flush with the surface of the street or roadway. The signal structure further includes a shaft 2 whose lower end is received by the socket member 1. A shoulder 3 is formed upon the lower end of the shaft 2 and the upper end of the socket 1 when the shaft is in position in the latter. A shOulder i is formed upon the upper intermediate portion of the shaft 2 and a traffic signal casing 5 is revolubly mounted upon the upper end of the shaft 2. The casing 5 is provided with angularly disposed side surfaces or panels 6 and each of the said panels bears a visible sign or legend 7 as for instance the word Stop and Go as illustrated in Figure l of the drawings. Other signs or legends may be employed if desired or required. The upper end of the casing 5 is pointed, as at 8, to shed the rain and the sign legends are set back from the corner portions of the casing 5 in order that they may not be obscured by rain, snow or A sleet.

The casing 5 is provided with a central tubular sleeve 9 which receives and turns on the upper end of the shaft 2. The lower end of this sleeve extends about six inches below the bottom of-the casing and provides a convenient hand hold to be grasped by the op erator in turning the casing. The lower end of the sleeve 9 bears against and works upon the shoulder 4.

The device is installed by planting the socket l in the road or street as hereinbefore described and by slipping the lower end of the shaft 2 into the socket. Thus the shaft is held in a vertical position and the officer may turn the signal casing to bring any particular legend of the signal to the view of the driver of an approaching vehicle. When no use is required for the signal the shaft 2 is lifted out of the socket member 1 and the shaft and easing are removed from the roadway or street, leaving the socket the fact that the upper end of the socket ng descr ed t nvent W at is claimed sz-j L In a signal structure, a socket member open at its upper end, a vertical shaft or 5 standard Whose lower end isreceived by said socket member, a shoulder formed. on the upper intermediate portion of said standard and a traffic signal casinghaving a central tubular sleeve receiving and revolubly V WILLIAM F.
