PAVING F ROADWAYS AND THE LIKE.
Specification of Letters Patent.

- To all whom it may concern.
Be it known that I, MORLAND Mrononr. DESSAU, a citizen of the United States of America, residing at London, England, have invented Improvements in or Relating-to the Pavings of Roadways and the like, of which the following-is a specification.
This invention relates to roadways in which a rubber or like surface is sectionally supported by blocks of adifferent mate:
rial, such as wood, to which the surface sections are suitably attached, as for example by interlocking.
The object of the invention is to effect improvements tending to a better securing of the surface sections of rubber or the like together and to the blocks so as to eliminate jointing troubles, and it includes the provision ofinterlocking edges upon the rubher or like surface sections which result in the direct formation between them of a seal preventing moisture gaining access to the supporting blocks. In the accompanying drawings, Figure 1 is a perspective View of a block cap according to the invention. Fig. 2 is an end elevation of two supporting blocks with rubber caps such as'in Fig. 1, shown in situ. Figs. 3 to 8 inclusive are views illustrating sundry modifications hereinafter more particularly referred to.
abutting surfaces of As shown in Figs. I and 2, the cap a of rubber or equivalent material (hereinafter referred to as rubber) has a series of projections b of dovetail shape in cross section arranged laterally on the underside and adapted to enter corresponding grooves formed in the top of the corresponding supporting blockc. One longitudinal side of the cap a is undercut at at so asto form with the block 0 a groove that overhangs the edge portion of the block, while the opposite longitudinal side of the cap .has a projecting rib 6 extending from the bottom to within a short distance of the top of the cap, so that such side iscomplementary in shape to the oppositeside, enabling the rib blocks a are preferably spaced apart and the interlocked edge portions ,of their caps a arranged to bridge the space 0 between them as shown. The greater portion of the the said interlockededge portions of the caps are; preferably made inclined, as shown, at an acute angle. The rubber cap a can be sprung on or otherwise afiixed to the block 0, an adhesive being employed to assist in the securing of the cap if so desired. Or the rubber cap may be molded upon the block 0 and afterward vulcanized. g
In Fig. 3 the supporting blocks 0 are shown fitted with a'modified form of cap,
the rib 6 being of less thickness or depth than that of the cap, so that the complementary groove 03 is formed} entirely in the cap so that a bottom ledge Z is provided for the rib e of an adjacent cap to bear upon.
If necessary the interlocking edges of the capsmay be fastened together, by pinning with material inserted in holes therein which material may initially be a liquid that will afterward harden and form a mechanically strong pin or plug, or of a natur dapted to be united to the caps by appropriate treatment, as by vulcanizing. Thus, in Fig. 4 the interlocking edges of the rubber caps, made of a shape according to Figs. 1 and 2, are shown as connected by pins or plugs f of rubber which may be vulcanized in situ after the blocks with caps have been laid The ends of the cap a may be likewise shaped the same as the sides, as shown in Fig. 5, which represents an arrangement similar to that of Fig, 3. As a further.
means of keeping the cap a securely fastened to the b 'ck 0, holes or openings may be cap 'projeetions '6 adapted to receive rods .of material designed to. lock the cap and block together. One way of effecting this is shown in 5, 9 representing a metal or other locking rod.
The ends ofthe cap a may beprovided with recesses adapted to receive metal clips made across and through theblockfand the driven into the block 0, after the cap is placed in position, for the purpose of holding the cap in place on the block. An ex: ample of this kind is shownin Fig. 6 where a metal clip h of dog shape is employed.
Instead of having each side of the cap a made differently as illustrated in connection cap, as in Fig 8, having corresponding grooves (1?.
If desired square orjothershaped pieces of stone, wood, metal or the like, not shown,
may be inserted in the rubber caps before these are vulcanized, and be fixed in place I byreason of the subsequent vulcanization of the rubber.
What I claim is 1. The combination with a horizontal supporting block of. a horizontal paving cap secured to said block and having an upper edge portion overhanging the adjacent side of the block and undercut to form a. groove extending back over part ofthe adjacent upper surface of the block.
2. The combination with a horizontal supporting block of a horizontal paving capfsecu-red to said block and having an upper edge portion with vertical face overhanglngthe adjacent side of the block and undercut from the lower edge of said vertical face, to form a groove that extends back over'part of the adjacent upper surface of 7 the block.
3. The combination with a supporting .block of a paving cap having an upper edge such block and a surface exoverhangin f tendingobliquely from such edge to a line set back in relation .to the side face of thea block which'isover-hung by the edge 'afore said. block of a paving caphalving an angular rib' .4. The combination with a .fsupporting formed by an inclined surface extending from a vertical upper "surface to a lower I horizontal surface that overhangs the block,
the "said. rib being complementary to the overhanging edge of anadjacent block cap which has a surface inclined downwardly and. inwardly from such. edge to a line set back in relation to the side face of the block .nal ed ge obliquely undercut and extending without break to the cap face and overhanging the supporting-block and the opposite longitudinal edge formed with an overhangnal edge that is-undercut formin a groove with abottomledge adapted to ar upon the top of the supporting block, substantially as described.
7 The combination with a supporting block, of a'paving cap having one longitudlnal edge undercut forming a groove with a bottom ledge adapted to bear upon the top of the supporting block and the o posite longitudinal edge formed with a ri complementary in shape-to the groove aforesaid, substantially as described.
8 The combination with a supporting block of a paving cap having an edge overhanging the adjacent side of said block and formed with a longitudinally extending groove of acute, angled cross section formed in said edge between its top and bottom above the upper surface of the at a higher level than the upper face of the block, the said rib being complementary to the angulargroove of'an adjacent block cap. 10. In a paving for a roadway or the like, supporting blocks spaced apart and paving caps secured upon said blocks, the
' edges of adjacent caps being formed the one with an angular groove and the other with a complementaryangular rib, the upper edge of the grooveand the lower edge of the rib oyerlappin'gthe adjacent sides of their respective blocks so that the engaged edge portions of the caps extend over and cover the space between the ad acent blocks. I
- .11..In combination, a wood supporting block grooved at the top and a rubber paving cap having projections upon the underside adapted'to enter the grooved top of the supporting block, said cap having one longitudinal edge formed with an acute angled groove and the opposite longitudinal edge formed with a rib complementary in shape to the groove aforesaid.
