This, invention relates. to markers in general and more particularly to a. marker for marking highways for. traflic purposes and the like.

One ofthe primev objects of the present invention. is; to provide a simple.l road markerincludi'ng a container so. constructed as to form an anchor andv reinforcement for the ller compound, with the? top. edge. ofV the container. disposed a predetermined. distance. below. the topA of the surface of the material of which the. highway is constructed.

Anotherobject istov provide a method of forming a marker receiving recessY of predetermined dimensions in the highway as it is being constructed, and in` which the marker can be easily and quickly installed.

A further object is to provide a road marker which is applicable to and which can be embedded or sety in` a plastic body ofV bituminous, cementi. tions and other forms, of plastic pavement.

Y A still further. Object. is to design a marker which includes a filler compound, the. face. of whichk is coveredl with a protective coating of highly wear-resistant material, which coating., is also.. possessed of highly, desirable; light reflecting qualities.-

Witlr the above and other objects in view, the present illvelltionconsists inthe combinationand arrangement of parts., hereinafterv more fully described, illustrated in the accompanying drawings, and more particularly. pointed out theapliendedclaims, it beinggunderstood that changes may. be. made in the. form, size, proportion, and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawings:

Fig. l is a top plan view showing my marker embedded in a pavement.

Fig. 2 is a sectional, edge elevational view taken on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged, sectional edge view showing the wearresistant coating in position.

Fig. 4 is a top plan view showing the removable ring and block used to mold the marker receiv-r ing recess in a pavement. l

Fig, 5 is a sectional edge view thereof.

Fig. 6 is a plan View of the contractable ring.

Referring now more specically to the drawings in which is shown the preferred embodiment of my invention. The pavement in which the marker is to be installed is indicated at P, and can be formed of any cementitious, bituminous, or plastic material, this marker is of predetermined size and depth, having a preferably crowned face as shown, and when embedded in position, this crowned face projects above the surface of the pavement, consequently, it is4 de'- sirable that these markers be installed after the pavement has been laid and nished, otherwise the projecting face would interfere with the use of a; straight 'edge or leveling board such as used in floating and finishing the surface of the pavement.

To provide for the install-ation of the marker after the pavement is finished, I mold a suitable recess 20 inthe pavement as it is beingcon structed, providing a fiat block 2|-, preferably but notV necessarily formed of, wood, and mounting asplit metal ring 2-'2-1 thereon so that it forms a rim for the block',said ring being resilient and i-s inwardly sprung so that it firmly clasps thelblock when assembled therein, and so that it contracts, asv indicated in Fig. 6- of the drawings, When the block i-sv removed. rFliis block 2|A can be in one piece as shown, or it can be split if desired, and' can be coveredwith a suitable lubricant to repell moisture and facilitate the` easy removal etc.

Inv practice, the block and ring assembly is placiedin predetermined position in the pavement as it is beinglaid, thevf-aceof the assembly beingy exactly ush with the face of the pavement, thusf eliminating any interference with a straight yedge; or otherr tools (not shown), utilized in the.

constructioni and` 'nishing of the pavement.

After the pavement materia-l has. setff the:

block-2li. is: removed, the ring 22 then. automaticallly:` contracts, as. indicated.. in Fig. 6 of the:

drawings, freeing itself from the material, and it can then be picked up for further use.

The marker proper comprises a cup-shaped stamping I0 which can be formed of metal, plastic, or other suitable material, said stamping having a centrally disposed opening II in the bottom Wall I2 thereof, and a plurality of circumferentially spaced-apart, raised sections I3 I are pressed in said wall. Openings I4 are provided in the raised sections I3 to permit flow of the filler compound F therethrough as the stamping is being lled, this compound when set, being securely anchored in the stamping, and the openings I4 further serve as air vents to permit escape of air as the stamping is'being filled.

To further lock and anchor the filler compound in the stamping, I enlarge the cylindrical section of the stamping at the point I5, directly adjacent the bottom wall, and when the compound is poured into the stamping, it readily ows into and fills this section, thus further anchoring the filler in position. The shape of the enlarged sections insures easy and thorough filling; it also magies 3 eliminates the forming of air pockets when the compound is being poured into the stamping, and the projection aids in anchoring the marker in the pavement.

In order that the marker, when installed, may be more readily observed by both drivers and pedestrians, it is formed with a convex upper face which projects above the face of the pavement, this convex facealso shedding rain, dirt and snow. When desired, this convex face is covered with a plastic skin or covering I6 (see Fig 3 of the drawings), said cover being formed with an annular rib l'l which overhangs the cylindrical skirt i8 which extends into the stamping, and a plurality of circumferentially spaced openings i9 are provided in this cylindrical skirt so that as the filler compound is poured into the stamping, it freely flows into said openings, and when the compound is set, the cover I6 will be securely held and locked in position, and this cover can also be formed with luminous beads embedded in the plastic covering, so that a luminous effect will be produced when vehicle lights are reflected thereon.

These markers are filled bottom-side up, and the nature of the outer skin or covering I6 precludes any chipping or cracking of the ller compound.

When installing the markers, the workman first places a dab of cement or other compound in the hole or recess 20, the pre-castrnarker is then'spotted in the recess and tapped to force it in proper depth, after which a hot sulphur compound S is poured in the surrounding space, this compound flowing in under and around the marker, and when set, securely anchors it in position.

I wish to direct particular attention to the fact that the upper edge of the stamping that contains the ller compound is disposed a predetermined depth below the face of the pavement when it is set in position, and this is of prime importance because no metal or sharp edges which might be worn or torn to produce sharp edges, etc., is exposed, thus eliminating the possibility of injury to vehicle tires on highspeed roads, there is no reflection of light on metal, but it nevertheless serves to Securely anchor the ller compound and prevents cracking or injury thereof.

While in the present instance I have shown and described a round marker. it will be understood that it is for the purpose of illustration only, and that the invention includes rectangular or any other desired shape, and all other modifcations and equivalents that fall within the scope of the subject matter claimed.

What I claim is:

1. A marking device of the class described comprising a rigid container formed with individual raised sections and perforations in the bottom wall thereof, a ller compound anchored in said container with its upper body portion projecting a predetermined distance above the upper edge of the container, a plastic skin forming a covering for the upper end of the container with the edges anchored in said container, and an overhanging rib formed on said covering, and disposed over the upper edge of the container.

2.*A marking device of the class described comprising a rigid container formed with individual raised sections and perforations in the bottom wall thereof, a ller compound anchored in said container with its upper body portion projecting a predetermined distance above the upper edge of the container, a plastic skin forming a covering for the upper end of the container, said covering being formed with a depending skirt section extending into said con tainer, and a plurality of openings in said skirt for admitting the filler compound to securely anchor the covering on the marker.
