Application filed April 11,
more or less distant from each other without contacting or abutting one another and being embedded in a layer of cement or concrete coming flush with the upper surface of the blocks. The said blocks, which form the frame or skeleton of the roadway, have a reduced weight in proportion to a comparatively important wearing thickness, the uncovered cast iron surfaces are small and preferably located in a direction at right angles to the direction of the traiiic on the area to be paved.
In the annexed drawing, given by way of example, Figure 1 is a plan view showing a ,down in suitable relative positions upon a foundation d of coarse concrete or any other material and embedded in a layer 6 of cement or thin concrete which is flush with the upper face or edge of the blocks. In Fig. 1, all the blocks a have the same shape. Fig. 2, two kinds of blocks 6 and 0 are shown for the purpose above mentioned.
Among the advantages of the improved Specification of Letters Patent.
I Patented July 2'7, 1920. 1919. Serial No. 2s9, 239.
pavement, the following may be cited Owing to the shape of the blocks they'may I easily be spread apart farther or closer at will so that different parts of the surfaces to be paved may be more or less strongly armored according to the strain to which they are subjected (middle part or sides of a road for instance).
The shape illustrated corresponds also to a reduced weight (varying from 011900 to lKlOO per block), so that the metal necessary for paving a square meterfor instance is about 25 kilograms at the maximum, which weight is low in proportion with other types already known and corresponds to an advantageous cost price. The wearing.
thickness of the blocks is comparatively important (about 4:0 mm.). The blocks have s only small uncovered cast iron surfaces, which lie mostly in a direction at right angles to that of the road. This acts efficiently to prevent slipping.
The roadway constructed as above described has a very long life and requires practically no upkeep, it stands perfectly neat even after snowfalls and frost.
The difficulty arising from the difference in hardness betweencast iron and concrete may be removed either byiusing a concrete comprising hard materials grit-stone, quartz, small trapp, etc., or by adding porphyry tothe cement, the mixture giving a product which is remarkably hard and similar to carborundum.
Having now described my invention what I claim as new and desire to secure by Letters Patent is 1. A pavement comprising in combination: a foundation, a concrete surface layer on said foundation, and cast iron blocks distant from each other in all of their parts,-
tion: a foundation, a surface layer comprised of cement and porphyry on said foundation and cast iron blocks distant from each other in all of their parts; embedded in said surface'layer and extending entirely throughout the same, each block being composed of a thin vertical Wall forming a closed figure of an approximately rectangular shape and outer radial arms, the arms on each block extending'between the arms'of the adjacent 10 blocks. i f In testimony whereof I have signed my name to this specification.
EMILE HENRY.
