Application filedmiay- 18,
This invention pertains new and novel means for marking the streets and safety zones in certain localities where vehicle traffic is exceedingly heavy and dangerous.
I 5 The present custom ofpainting traffic lines to indicate center streets, cross walks on streets and street car Zones, etc., has the d1s advantage that the lines wear off and must be repainted constantly.
It has also been found that white, black, red and amber colors are the most suitable colors for mankers to insure visibility, and it has been found that markers that have a surface even of a light alloy metal as brass,
copper or German silver do not bring the de= sirable results. v
The object of my invention isto provide a street traflic marker that will be cheap to ,manufacture and will provide at the same time the desirable coloring to insure visibility,
and thus eliminate the painting of traflic lines. T
Another object of my invention is to so construct my traflic marker that it will indicate '25 any desired coloring on the upper face of the marker, and that such color will be further permanently maintained by providing studs or projections on said upper face of the marker in such a manner that they will pro tect the recessed colored surfaces between the studs or projections from wearing off while traflic moves on'the upper surface of the marker, since the studs'or projections will ward off any object that may travel on the marker from getting in contact with the recessed colored surface so as to efface the coloring. I Another object of my invention is to add additional durability and attractiveness to the upper surface of the marker by covering or coating the said vupper face with baked enamel of any desired color, and to so arrange the studs or projections on its upper surface that it will protect the chipping off of the enamel between the recesses .when traffic moves over the upper surface of the marker.
Another object of my invention is to so construct my marker that when it is desired to economize in-the use of material of which the marker is composed that thebottom surface of the marker may be hollow and to provide integral reinforcements inside of the hollow surface.
Another object of the invention is to so construct my improved marker that it may be readily installed within the street pavement zoiniwe MARKER FOR STREET TRAFFIC.

regardless of the material of which the street 'is constructed; that it will be always maintained permanently in the desired position; and'that it. may be disposedfiush with the surface of the street or slightly above the street surface.
'lhe foregoing and such other objects as may appear from the ensuing descriptionare attained by the construction, arrangement and location of the parts hereinafter more fully described, illustrated in the accompany ing drawings and more'p-articularly pointed out in the claim appended hereto, it being understood that slight changes in the precise form, proportions, and minor details of construction may be resorted to without depart- I ing from the spirit 'or sacrificing any of the advantages of the invention;
In the accompanying drawings forming a part of this specification it will be seen that: Figure 1 is a plan view of the improved .means embodying my invention.
Figure 2 is, a transverse section thereof taken in theplane of the dotted lines 2-2 Fig. 1.
' Figure 3-i's a longitudinal section taken in d I the plane of the dotted lines 33, Fig. 1.
Figure 4 is a plan view of a slightly modified form.
Figure 5 is a section taken in the the-dotted lines 55, Fig. t.
Figure 6 is-a plan view of'further modified form. Figure 7 is a cross-section taken in the plane of plane of the dotted lines 7+7, Fig. 6, and
Figure 8 is a plan View of one other slightly modified form. I
In the embodiment'of my invention as il- 'I lustrated it will be seen that the numeral 1 designates a zone marker, providedat its lowermost portion with a laterally extending. flange 2, and formed with a central downwardly extended strengthening portion 3, a downwardly extended wall 4 formed at the sides and ends thereof, while the inner por-- tion. thereof is hollow, the extended flange 2 serving to lock the marker within the street pavement, and in connection with the wall 4 to maintain said marker in its fixed and permanent condition atall times and under all conditions.
The upper or top portion of the marker is formed of a portion 5, curved orarch-shaped from one side to-the other, its upper face or surface being" formed with a series ofoutw'ardly extended projections 6, and a series of recesses or depressions 7 intervening be-. tween sald pro ections', each of the saidrea cesses or depressions being preferably curved or rounded at their ends and sides for the purpose of drawing'off foreign material that may collect between-the recesses and thus 'maintainithe colored surface cleansed and visible as hereinafter described. 1
, My improved marker is preferably coated or enameled over its upper face or surface with a suitable,'easily visible coloring material, preferably baked enamel, and while the projecting surfaces will form a top surface of metal, rubber, or other composition over which vtraflic may travel, the recessed portions being out of contact'with the heavy traffic will always maintain its readily 'visible color, under all conditions, and owing to the ticular type of marker may be formed of any.
sloping sides and ends of the depressionsor recesses, any dirt, dust, or other foreign material which may accumulate therein, is
.readily and easily cleaned out by the usual winds and rainfalls, thus always maintaining a readily visible color to indicate the safety zones and crossing lines to drivers of vehicles of all kinds, as well as to pedestrians.
It will be readily perceived that this parsuitable or desirable material possessing the required strength such as castings, pressed sheet metal or a composition to be embedded or installed within. the material which constitutes the street pavement; that it may be coated or enameled with any suitable, readily visible coloring material, and that the marker may be formed of any suitable or desirable dimensions, contour, or letters, which may prove most desirable for t e location and the purpose for whichit is in ended to be used, that is, for street crossings, safety zones;
I and side-walks.
By reference to 4 and5 of the drawings it- 'willtbe seen that a slightly modified form of structure or marker is shown, said structure or'marker'to be installed within the street pavement, and is prov ded with anoutwardly extended flange 8 at its lower end, while its top wall 9 is provided upon 1t s upper face with a series of pro ect1ons 10 and 10', said projections being of different pense with the expense of frequently painting the traffic lines and safety'zones on the street pavements, which lines and zones are frequently invisible to the traflic.
Referring to Figs. 6,7 and 8 of the drawings which disclose further slightly modified forms of the invention, the numeral 13 inllwhich is formed of any desirable material, said cover being provided with a series of slightly raised or projecting portions 15, and depressions 16, formed intermediate said projecting portions, said cover being secured in any suitable or desirable manner to said-frame, said depression being coated or enameled with 1 any suitable visible color,
distinguishable coloring, and since the depressions are not subjected to wear by the heavy traflic, the marker will always be easily and readily visible.
It will be understood that the projecting surfaces'may be suitably serrated or roughened to prevent accidental slippingduring passage thereover. Having thus described my invention-what dicates a frame, having a removable cover preferably white baked enamel or any other I I claim and desire to secure by Letters Pat.- I
cut is: v
In a device of the'character described, a
structure having its top surface curved along the longitudinal and transverse axes and provided over its entire surface with projections, the surface between same being coated with material to give same distinct visibility, the projections being of such height and so spaced as to prevent tires from scraping the coated surface and to act as a non-slipping surface, the curvature of the recessedsurface being such as to, permit free drainage and to prevent normally, the collection of dirt.
