Application filed May 7, 11931. 'Serial No. 535,702.

My invention 'relates'to'metal tiles of preselected dimensionsintended to constitute the,

wear-receiving surface of a highway, drive or runway and adapted to be placed on-a road 5 surface at the time of construction to permit certain depending portions of the tile to embed themselves in the road surface so as to firmly anchor the metal tiles in place.

The object of my invention is to provide a non-flexing tile providedwith a traction providing surface, with the lower sideof the tile provided with a. plurality of anchoring portions which cause the tile to beheld against i movement; the tile being especially intended for use on concrete roads ortrucking runways where the latter are subjected to heavy wear's'o as to protect the concrete against disintegrating or destructive effect resulting from the frictional and pounding action of passing traffic F 3b substantially on the line 2-'2 The objects and advantages of myinvention will be readily comprehended from the detailed description of the accompanying drawings, wherein:

- 7 Figure 1 is a top plan view of'my improved paving tile in position ona roadway; a complete tile being shown and portions of ]11X- taposed tiles being shown at opposite sldes.

Figure 4 is a sectionalview similar to Figure 2, illustrating a modified form of the paving tile. 7

Figure 5 is a plan view, similar to Figure "40 l,'illustrating another modified form of my t improved paving tile.

Figure 6 is a longitudinal sectional view of 'Figtaken substantially'onthe line 6 -6 ure 5 as viewed by the arrows. v My improved paving tile is formed of suittiles to be arranged in close juxtapositionso able metal, either cast or pressed into'shape cast iron being preferably employed' because of its non-rusting nature; and the tiles are preferably of polygonal form to permitthe road surface is still in a more or less plastic as to provide a continuous wear resisting surface fora-preselected locality in the roadway. The tiles are of any predetermined dimensions'which will permit easy handling and are of a thickness so as to be wear resisting and afford full protection for the surface of the road or run-way. My improved metal tile is'intended to be laid in place while the v ings consists of suitable sized metal plates 10, having straight side edges and preferably of the rectangular shape shown. a

. In Figure 11 illustrate a complete tile 10, with portions of tiles at each side and along the bottom of the figure. As all of these tiles are of similar construction and'configuration a description of one tile will suffice.

The tile at itsperimeter, namely along all of its edges, is provided with a depending flange portion 11 provided with a straight vertical outer face, see Figure 2, so as to permit aaflush abutting relation with the perimeters of the adjacent tiles. These flange portions 11, on their inner faces and adjacent to the lower marginal edges thereof, are

formed with the laterally disposed enlarge 7 Each tile 10, in addition to the marginal w flanges described, are also provided with transverse, intersecting depending ribs or portions 13,13, which extend from side to side along the bottom of the tile and preferably unite at their ends with the'marginal H depending portions 11. The transversely disposed depending portions 13, 13, adjacent to theirflower longitudinal edges, are enlarged laterally on opposite sides of the median lines thereof, as shown atli (see Figure 3), with we the enlargements preferably provided with f crete or soft material and the road material.

or concrete will enter the space between the enlarged heads 12, 14 and the lower side of the tile. t is apparent, when the concrete becomes set or hardens, that the tile will be immovably anchored in place andpractically become an integral part of the roadway; while at the same time the marginal depending portions 11 will prevent lateral displacement ofthe moldable or cementitious material beyond the outer sides of the tiles at opposite sides of the roadway.

I Each tile 10, in the form shown in Figures 1 to 3, are provided with symmetrically spaced relatively large openings at15, preferably of the circular formation shown.

These openings are provided with sloping converging sides as shown at 16 inFigures 2 and 3 andthe lower side of the tile around the openings is provided with depending encircling flanges 17 which initially are arranged in alignment with the sloping sides of the openings in the tile proper and the flanges 17 then disposed in the laterally diverging manner, at their lower ends, as shown at 18.

- It isapparent that the plastic material or concrete of the roadway, which enters the tile when the latter is pressed into place, will not only form a binding relation with the tile because of the gradually increasing di ameter-of the hole toward the upper face of the tile, buta further anchoring-eflect is ob tained by the unset concrete flowing into the chamfer or encircling socket on the lower side of the tile formed by the oppositely sloping flange portionsl17 V and 18.

The openings 15 are preferably intended to be completely filled with the sub-surface material or concrete from which the roadway is made, and therefore concrete may .be poured into the openings 15 beforethe subsurface has become set or hardened so as to bring the concrete flush with the top sur face of the tile. r y 7 The tile, in addition to its anchorage by the depending portions 11 and 13, will be further securely held in place'hy the dual anchorage provided by the formation 'of'the openings and the encircling flanges at th lower sides.

In Figure 4 I illustrate a slight modification of the tile shown in Figure 1, insofar as the opening encircling flange -is concerned, the tile 10 of Figure 4 it willbe sloping top and bottom sides, thereby formunderstood is to be provided with the marginal depending headed flanges 11 and the transverse intersecting headed ribs or'portions 13 on the bottom side of the tile like that heretofore described.

,In the form shown in Figure 4, the tile 10% is also providedat prearranged spaced points with relative large openings 15 having converging sides and the lower side of I the-tile provided with the encircling flanges 19 arranged in keeping with the sloping converging sides of the openings in the main part of the tile. That is to say, the flanges '19 continue in a straight line or direction x and are not of the angular formation shown in the preceding figures; the flanges 19 preferablytapering somewhat toward the-bottom as shown. stated, are to be filled with concrete before the under-pavement becomes set, thus, like in Figure 1-, providing the comparatively deepconcrete locking and integral wedge portions which, in addition to the marginal portions 11 and the transverse portions 13, will firmly anchor the tile to thesubjacent material ofthe roadway.-

In Figures 5 and 6, I illustrate another modified form of my improved tile; the tile l0 being made without the sub-surface receiving openings of the tiles shown in Figures 1 and 4. The tile 10*, like the previously described forms, being providedv with the marginal fiangesll having the laterally ex.- tending substantially V -shape headportions 12 and with the transverse intersecting depending rib portions 13 provided with the somewhat diamond shape or enlarged tapered head portions 14a The head portions The openings, as previously 12 and 14 being arrangedat a slight, distance beneath the bottom face of the tile,permit the concrete ormaterial from which the road is'constructed toflow orenter the grooveways formed above the head portions and as aresult the tile will-be firmly united with the roadway when the concrete or material hardens. v The top of-the tiles are all preferablyprovided with traction providingsurfaoes consisting of series of pyramidal portions 20. Aside from afl'ordingtraction, these-pyramidal portions provide forincreased strength in the tile and greater wearing quality;

i A metallic tile comprising a flat plate of preselected dimensions and shape, the perimeter of the plate having a continuous depending flange while the bottom of the plate is provided with transversely disposed in tersecting flanges, all of the flanges adjacent their lower marginal edges being laterally enlarged and said enlargements having oppositely beveled faces'to' provide a lower wedging surface and an upperlocking surface adapted to be pressed into a roadway surface; the plate being, provided with paving material receiving openings of comparative size having side walls converging toward the bottom of the plate, said openings being surrounded by depending flanges with the lower ends of the flanges being disposed in a. direction reverse-to that of theupper parts of 'theflanges whereby the plates are locked in the sub-surface.
