PAVING BLOCK AND TILE.

Application filed March 10, 1923. Serial N o. 624,227.

Our invention relates to certain improvements in paving blocks and tiles, which are imbedded in a base of concrete, or other suitable supporting material.

5 One object of our invention is to make a p ving block, or tile, of metal provided with a rubber face.

A further object of the invention is to design the block, or tile, so that the rubber 10 face will extend beyond the edge of the metal body .portion so that, when the blocks, or tiles, are laid, the rubber faces of adjoining locks will be in Contact to allow for expansion and contraction.

In the accompanying drawings:

block made in accordance with our invention;

Fig. 2 is a plan view;

F ig. 3 is an inverted plan view of a paving block; and

yFig. 4 is a sectional elevation, showing a series of blocks imbedded in concrete.

In the present instance, l is a rectangular metallic block having a base portion 2 and deep flanges 3 on all four sides. These flanges are perforated, as at l and 5, to allow the concrete base 6, while in a plastic condition, to pass through the openings. It :zo will be understood that the flanges are 1mbedded in the concrete. block is perforated at 7. 8 is a rubber face of any depth desired. This rubber face'has projections 9, which pass through openings in the base of the metallic block. Buttons l0 are formed on these projections 9 dur-k ing the process of vulcanization so as to lock the rubber face firmly to the base of the block.

It will be understood that the rubber 'luce is formed in a mold, in which the metallic.

block is inserted The rubber face 8 is e2:-

tended beyond the edge of the metallic block,

as shown, and a. flange ll extends below the -15 face, forming a yielding abutment for an adjoining block.

The object of this construction is to allow the blocks to be placed in position with the edges of the rubber faces in contact. This arrangement allows for expansion and contraction and prevents the joints between the blocks separating. This construction also Fie'. l is a perspective view of a paving The base 2 of they prevents water gaining access to the spaces between the blocks and freezing when the pavement is subjected to low temperatures. A pavement made in this manner is very substantial.

The faces of the blocks yield when subjected to pressure of vehicles and they are substantially noiseless. The flanges of the blocks may be of any depth desired. In some instances, they may be of a greater depth than shown, where the concrete base will admit of such construction. The flanges can be reduced to such an extent that the block can be used as a tile for flooring.

l/Vhile a rectangular design' is Shown, the shape of the block may be varied without departing from the essential features of 'the invention,

`We claim: i l l. The combination in a paving block, or tile, of an open, flanged, metallic block, shaped to be imbedded in the face of a pavement and having perforations in its upper surface; and a series of buttoned projections extending through the perforations andengaging the block.

2. The combination inV a paving block, or

tile, of a .flanged metallic block having` a 1 perforated base', and a rubber facchaving projections extending through the perforations of the base, the said projections having buttons of a greater diameter than the perfoii'ations. j

3. The combination ina paving block, or tile, of an open metallic block having a perfoi-ated base and perforated flanges; and a rubber face secured to the base of the bloot: by a series of buttoned projections, the rubH ber face having flanges extending at the sides of the metallic block.

4f. rThe combination in a paving block, or tile7 of an open rectangular, metallic block having a perforatedbase and extended perforated flanges; a yielding face of rubber ,havingV projections extending through the perforations in the base of the metallic block; buttons on the extensions coni'ining the face to the base of the block; and flanges on the rubber face extending atftbe sides of the metallic block.
