R. H. SMITH March 18, 1930.
PAVEMENT Filed July 17, 1925 Patented Mar. 18, 1930 [UNITED STATES RUSSELL H. SMITH, F BBO OK FIELD, MASSACHUSETTS PAVEMENT Application filed July 17,.
It is desirable that pavements shall be more or less resilient and as far as possible noiseless under traffic. To this end pavements having a bituminous wearingsurface have been used and also with a rubber wearing surface. One difficulty with these two classes of pavements has been that the wearing surface has had a tendency to crawl under the influence of traffic so that it becomes uneven on the surface and wears unevenly. Various means have been utilized with a desire to overcome this fault, but so far as I know none of them has proved satisfactory.
My improvement now to be described IS preferably utilized in block form, and it comprises a paving block made of some resllient material, such for example as rubber, with means for anchoring it firmly to a proper foundation. As shown two means are provided, but each of them has the same characteristic, viz: that of an element which shall project from the foundation into the paving block or from the paving block into the foundation.
My invention will be understood by reference to the drawings, in which- Figure 1 shows the plan of a paving block embodying my invention.
Fig. 2 is a section on line 2-2 of Fig. 1 showing the block in position on a foundation and attached thereto.
I Fig. 3 is a similar view taken on line 33 of Fig. 1, and
Fig. 4 is a sectional view taken on line H of Fig. 1.
1 is a paving block of any suitable size and preferably made of reclaimed rubber or other resilient material. 2 are recesses moulded in the under surface of the block and capable of receiving a material like that of the foundation, this material being shown at 3. 4, 4. are metal bars or wires which, if the block is of rubber, are vulcanized in the block, these rods or wires being of sufficient length to be bent down through the bottom surface of the block and, if desired, to be bent laterally as shown in Fig. 4 at 5 so as to get a good hold in the foundation. These metal bars, rods or 59 Wires 4 are preferably in two sets disposed di- 1925. Serial No. 44,240.
agonally in the rubber layer 1 and cross each other at right angles, as shown in Fig. 1.
In its preferred use this block is laid on a concrete foundation while the concrete is still Wet and unset and, previous to being laid, the cavities 2 in the under surface of the block are preferably filled with concrete or the like so that when the block is set in place the concrete in these cavities unites with the concrete forming the foundation of the pavement. The process of course might be reversed by forming on the surface of the foundation properly shaped masses of concrete located to register with the cavities in the block, the point being to get a sufiicient union between the concrete in the cavities and the concrete in the foundation to prevent the block from crawling in either direction when the concrete has set.
l I s P The wires or rods answer a slmllar purpose.
A considerable length of rod as shown proj-ects below the lower surface of the block and in laying, the block is laid on the foundation concrete and the wires are forced into the concrete before it is set so that after it is set the ends of the rods or wires are firmly embedded in the foundation, sure to hold the block in place.
It will be understood that either or both of these modes of tying the block to the foundation may be used with good results, and it Will be seen of course that in either casethe union will be such as to prevent the block fro-m crawling on the foundation.
While I have used the word concrete as 1 the material of which the foundation is comthe recesses in the block, I do not mean to limit rials may be used for a foundation. The maposed and also the material to co-operate with terial filling the recesses should be such as will i attach theblock to the material of which the foundation is made. I have also referred to rubber as the preferred material of which laid with the rubber into the vulcanizing the block is made, but it will be evident to one 7 V moulds and the block is then vulcanized in the usual Way so that the ire is firmly embedded therein With its ends projecting therefrom, as will be readily understood by those skilled in the vulcanizing art.
What I claim as my invention is-- A paving block, of resilient moldable and vulcanizable material, providedon its under side with recesses for the reception of Wet unset concrete foundation material to enter said recesses to lock saidrblocklto-the ;;foun-dation, said block having, embedded and vulcanized in its body two crossing sets of anchoring an'cl reinforcing Wires having inclined downwardr ly-turned and then inwardly-turned projecting p rts to en r the we un undation material, to assist inbinding said block to said foundation, said inwardly turned parts'being at some distance below the lower surface of said block, and each being of alength approx-- 'imately equal tohalf the length of said block.
