Itis a principal object of this invention, there- As shown in Figures 1 to 3, each section of my fore, to provide an improved traflicseparator or improved traffic guide consists of a narrow solid 30 guide having its side walls so formed that it is body or block 9 of cast iron,or other strongmateless likely to afiord sufficient traction surface for rial, having a flanged base Hi, the side walls of the wheel of "a swerving-vehicle to climb over it, the base tapering upwardly so that when embut will i tend to guide an obliquely impinging bedded in the pavement 25 the base presents sides wheel back on the proper course Without sub- Hll of substantial area against the paving ma- 35 jecting the-vehicle to undue shock or damage. ,terial in the relation of an inverted keystone,
Another object is to provide an improved structhereby firmly anchoring the device in the paveture of light weight and great strength which ment. will occupy a minimum of space in the roadway.

Formed in this manner the deat substantial distances and without requiring vice is comparatively light and economical of ma- 50 the motorist to divert his attention from the roadterial and the lightness and economy are obtained way. A further object is to provide such inclined without sacrificing materially the strength esend portions at angles such that a wheel driven sential for its purposes. against the end of a section may easily ride up The upper portions at either or both ends of onto the top of the device and the vehicle will each section are inclined at an angle of about 55 forty-five degrees, thereby providing upwardly and outwardly facing display areas l6 for traffic markings, such as the direction indicators shown. Such markings are preferably represented in materials of contrasting color having high light refleeting properties sunken or recessed in the display surfaces.
Each section 9 is preferably of an over-all height of about twelve inches, of which approximately four or five inches, including the base if), is embedded in the pavement. The sections may be of any convenient lengths and for the purposes illustrated in Figure 4 I have found that lengths of about five feet are well suited. Shorter sections, such as illustrated in Figures 1-3, will be found useful for the junctions of forked roads or for defining and bounding the limits of safety zones, or trolley car stations as illustrated in Figure 6.
Referring particularly to Figure 4, the sections are embedded in the pavement 25 in end to end relation intermediate the side walks 2626. The sections may be placed in close abutment or with a space between 21 to permit drainage. They may also be made in forms curved to conform to the curves in the road or highway, if desired, although the use of straight sections of moderate length can usually be satisfactorily arranged slightly out of alignment to accommodate all ordinary road curvatures.
Installations on new roads will require only that the sections be set in position on the road foundation preliminary to the emplacement of the surface paving. Installations on existing streets or highways will only require cutting a small section of the road surface due to the narrowness of the sections.
Installed on the road in the manner illustrated in Figure 4, the sections afford a substantially continuous guard or guide calculated to prevent violation of various traffic regulations, preventing automobiles from going out of line into the wrong side of the road, preventing U turns, and discouraging speeding. Being narrow, my improved guide occupies a minimum of space which might otherwise be made available to traffic and, being of substantial height above the pavement, pedestrians are discouraged from attempting crossings except at proper intersections.
Aside from the lightness, economy, and strength of the sections and the space economy they obtain, their peculiar shape obtains important advantages. For instance, if the wheel 36 of an automobile should impinge endwise against an endmost section, as indicated in Figure 2, the inclination of the display surfaces, being tangential to the periphery of the wheel, will afford traction for it and permit the wheel to roll up onto the top surface of the section without damage or undue shock. If a car running substantially parallel to the guard swerves against it, the tire of the car wheel will obliquely impinge only against one of the narrow flanges l5, as indicated in Figure 3, and since the flange is very narrow, insufficient traction is afforded for the wheel to climb over the guard and the wheel is caused to pivot back on a proper course. When the device is made of metal, such as cast iron, or other smooth material, and particularly when the narrow flanges l5 are rounded as shown in Figure 5, the tire of a wheel riding against the guard will be subjected to very little, abrasion or wear.
If the side walls as well as the top are painted, tires cannot ride against the recessed areas of the side walls and therefore will not wear away the paint. The display surfaces H5 at the ends of the sections are faced in the normal plane of vision of the vehicle operators and may be marked to give ample and frequent warnings or directions which will be readable at considerable distances without requiring that the motorist divert his attention from the road.
Short sections may be conveniently and effectively employed to define or bound the limits. of safety zones or trolley car stations. A plurality of short parallel sections arranged for the latter use are illustrated in Figure 6 in which 25 indicates the roadway, 2B'-26 the sidewalks, and the trolley car tracks are designated at 28. On the near side of the intersection, the sections 9-9 protect the trolley station 29 and their outwardly facing display surfaces are appropriately marked as shown in Figure 7. Other and further arrangements and uses will occur to those skilled in the art to which this invention relates.
Having thus described my invention, I claim:
In a roadway, a traflic guide comprising a plurality of oblong sections arranged end to end, each of said sections having a base portion embedded in the roadway and an integral portion projecting above the surface of the roadway a distance less than the radius of a road wheel, a narrow outwardly extending flange at opposite sides of the top of each section, the side walls of each section being recessive betweeen said flanges and the surface of the roadway, whereby a vehicle wheel impinging against a side of the guide can abut only against said flanges, upper end portions of certain of said sections being beveled, the slope of said beveled portions being substantially tangential to the periphery of a vehicle road I wheel.
