PAVING CONSTRUCTION.
application filed June 11, 19%. Serial No. 36,295.
This invention relates to a paving construction, more particularly to the construction of a paving unit or block and its anchoring means, which is especially adaptable a for use with rubber pavements.
Heretofore in connection with the utilization of rubber paving blocks as a surface for roads, sidewalks, bridges, etc., various expedients have been proposed for anchoring to them to the foundation or base ofthe roadway. Frojecting lugs of rubber molded integral with the block and adapted to be buried in concrete before it sets have been tried but found unsatisfactory in that they to work loose or separate. Various forms of projections and recesses constituting a species of lap joints have been provided on the blocks or rubber units, but these have been found objectionable for the reason that but an a fraction of the thickness of the block is utilized for the anchorage, and further, they have necessitated the use of expensive and intricate mold equipment. These and other erpedients have been employed, but none to have been entirely satisfactory.
The present invention aims to provide a type of paving block and anchorage which is inexpensive to manufacture, reliable and positive in use, capable of application to various types of foundation, but especially to a planlr base such as is used on bridges, which utilizes ordinary fastening devices not requiring any skilled labor, does not require the use of cements, and generally,
as represents a long sought desideratum in the art. It also aims to provide an anchorage or fastening which is applied from the upper or wearing surface of the pavement an which will permit the removal of any unit without disturbance of the surrounding ones. lit further aims to provide a corner anchorage for the paving units with the use of a minimum number of fastenings, and to provide an anchorage forming part of the wearing surface and having similar physical properties to the latter.
l llith the illustrated embodiments of the invention in mind, but without intention to limit the scope more than is required by the prior art, the invention, briefly stated, con sists in the use of tapering plugs of conical, pyramidal, or other flaring shape, and pro vided wtih means for securing them to a base, which plugs are ada ted to fit in complementary recesses forine preferably in the corners of adjoining blocks, but which may be additionally formed in the side walls or within the bodies of the blocks or in all three locations. The plugs may be made of any suitable yielding material but preferably are 0 made of the same composition as the bod of the paving blocks, these latter being pref erably made of vulcanized rubber suitably compounded to provide the necessary resilience, strength, and resistance to abrasion as in street traffic, the plugs when in place forming part of the wearing surface.
For a detailed disclosure of the nature and objects of the invention reference is bad to the accompanying specification and draw- 70 ings, in which latter,
Fig. l is a perspective of a paving block or unit formed with recesses shaped according to one embodiment of the invention;
Fig. 2 is a perspective of a similar block 75 illustrating another embodiment of the invention;
Figs. 3, 4i and 5 illustrate blocks embodyingother forms of the invention;
Figs. 6, '1, 8, 9, 10, 11, and 12 illustrate in so perspective different forms of anchorages for use with the blocks shown in the previously described figures; and
Figs. 13, 14, 15, 16, 17, and 18 illustrate in perspective various types of pavements an as laid using the various forms of blocks and anchorages.
Referring to the drawings the numeral 1 (Figure l) designates a paving block or unit which may be of any suitable material, but an as the invention is particularly applicable for use with rubber pavements it is preferred 1 to make the block of a suitable rubber composition. In the form shown in Figure 1 the block is of rectangular shape and is pro- 96 vided at each corner with inclined cutaway portions 2 as shown. It will be seen from Figure 13 that when this block is laid, the cut-away portion at each corner forms, in conjunction with the cut-away portions of 10a three adjoining blocks, a wedge-shaped recess similanto the wedge-shaped recess 3 shown in the body of the block. if desired the block may he also provided with cut-away portions on its edges intermediate the cor- 105 ners, said portions being of the general shape indicated at l so that each cut-away portion ain conjunction with the cut-away portion of an adjoining block or blocks will orm a wedge-shaped recess similar to the no wedge-shaped recess 3 shown in the body of the block. It is particularly desirable that the blocks be securely fastened at the corners, but the blocks can also be equipped with either the cut-away portions st or 3 or with both in addition to the corner cut-away portions 2. In the case of pavements termed with small units or blocks it may be sullicient to fasten them at the corners, while with larger units or units of an elongated shape it may be desirable to also use the body recesses or the intermediate edge recesses in addition to the corner ones. Preterably small cut-away portions also extend from the bottom of each recess to the bottom of the block to form screw or nail holes for a purpose later described. When laying the blocks they are placed edge to edge, and in the form of pavement shown in Figure 13 they are also placed corner to corner, and in each corner recess there is then disposed a wedge-shaped anchorage member or plug 5 such as shown in Figure 6. This anchorage member is preferably formed of the same composition as the block and is of a shape complementary to the recess in which it is to be disposed. To secure the plug or anchorage member in place it is provided with some form of fastening such as the screw 6 shown in Figure (3. and in order to firmly hold the screw in the body of the plug the latter may have molded or otherwise disposcd therein a metallic washer 7. In place of the screw 6 there may be used nails 8 as shown in Figures 7 and 8, and there may also be substituted for the washer 7 a piece of wire mesh or fabric 9 as shown in Figure 7, or a piece of hard rubber 10 as shown in Figure v8.
Figure 13 shows a perspective of a pave ment formed of blocks such as shown in Figure 1, the blocks in this embodiment being provided with corner recesses only. If in addition intermediate edge recesses are provided in the blocks they may be either laid in the same arrangement as shown in Figure 13 or alternatively may be laid in a staggered form similar to that shown in Figure 18.
In the modified form of block shown in Figure 2 the block 11 is provided at its corners with a bevelled triangular cutaway portion 12, and it will be seen that this portion will in conjunction with the corners of three adjoining blocks form a four-sided pyramidal recess in the manner shown in Figure 14. The block may also if desired be formed at its intermediate edge portions with cut-away portions 13 each forming half of a four-sided pyramidal recess. and it can also be provided in its 'main body portion with an entire pyramidal recess 14. In order to anchor the block of this modification in place on a base a pyramidal anchoring plug 15 is provided as shown in Figure 9, which is of a size to exactly fit in the recesses with its top surface preferably flush with the top surface of the block. The anchorage plug 15 may be provided with any suitable fastening means such as the nail 8 as shown in Figures 7 and 8, but instead of the nail there may be substituted the screw (5 shown in Figure 6. The plug 15 is also provided with a metallic washer 'Z, for holding the nail or screw in place, and this washer may be substituted by any of its equivalents as shown in Fi ures 7 and 8. The block shown in this modification may be laid in a corner to corner arrangement as shown in Figure 14 or alternatively it may be laid in a staggered arrangement similar to Figure 18. It is also obvious that since the corner recesses are formed by merely bevelling off the corner of the block, when using this form of anchorage the blocks may be made in other shapes than rectangular, such as triangular or hexagonal, the anchorage plugs in this case being in the form of hexagonal or triangular pyramids as the case may be.
In the form shown in Figure 3 the block 16 is formed at its corners with tapering arcuatc or quarter conical cut-away portions 17, and when the blocks are laid the cutaway portions at four adjoining corners together t'orm a conical recess. As in the previously described forms additional recesses may be provided by forming half conical cut-away portions 18 in the side edges of the blocks and if desired complete conical recesses 19 ma be formed in the body of the block. In his block there are also shown shallow grooves 20 cut in the surface of the block, which grooves may be made to form any desired pattern and give increased traction. These grooves or modifications of them may also obviously be formed in any of the embodiments of the invention. To secure this type of block in position on a foundation, conical plugs 21 are provided as shown in Figure 10, and these plugs may be provided with fastenin screws 22 similar to the screw 6 or instea if desired nails may be used. As shown the plugs are provided with embedded metallic washers 23 similar to the washer 7, but any of the equivalents for these washers shown in Fig ures 7 and 8 may be used. The block 16 may be laid in any of the arrangements previously or later described, using side edge or central recesses or both in addition to the corner ones, as may be deemed necessary or desirable. In Figure 15 is shown a pavement formed of a block similar to that shown in Figure 3 but without the surface grooving 20 and without the side cut-away portions 18 so that the blocks are secured only at their corners and in the body portion. Figure 16 shows a pavement similar in all respects to Figure 15 but with the loo lab
body recesses 19 omitted from the blocks and with the intermediate edge recesses 18 substituted.
In Figure 4 there is shown a block 24 similar to that shown in Figure 3, but the corner cut-away portions 25 instead of being conical in general contour are of a part cylindrical shape at 26 adjacent the surface of the block and below this of a part frustoconical shape at 27. In Figure 11 there is shown a plug 28 of a shape adapted to tit into four adjoining recesses of the type just described and it will be seen that the bottom of the recess 25 forms a seat against which the end of the plug 28 may rest. The plug 28 may be provided with any of the fastening devices shown in Figures 6, i and 8.. Side recesses 25 and body recesses 26 may be used where desired or necessary. Figure 1'? there is shown a pavement having the blocks 24 in a staggered arrangement using corner and side recesses, but a corner to corner arrangement similar to Figures 13 to 16 may be used instead.
in the modification shown in Figure 5 the bloclr 29 is provided at its corners with tapering arcuate or quarter conical cutaway portions 30 which aresimilar to the cut-away portions 17 in the blocks 16 but they extend through the block sutiicientiy to bring the point or apex of the cut-away portion at the lower surface of the block. The block may also be provided with semi-conical cut-away portions 31 along its edges and with entire conical recesses 32 in its body, if desired. The manner of laying and securing this block is similar in all respects to that of the block 16, the only difierence being that the anchoring plug 33 is made of a length sufiicient to fit the recesses. In Figure 18 is shown a pavement formed of blocks similar to the blocks 29 but with the central recesses 32 omitted, the blocks being laid in a staggered arrangement.
It will be seen. that in all forms of my invention the paving block is securely anchored at the corner and this anchorage is secured with a minimum number of restenings consistent with the desired strength, the intermediate edge recesses and plugs and the body recesses and plugs being only necessary where the block is of considerable or elongated or where it is desired to lay the blocks in a staggered arrangement, While it is not essential that the plugs be llush with the balance of the pavement it is preferred to form them in this manner, and is thus formed a smooth pavement ich is of uniform yielding and wearing in 'tv throughout its surface owing to the that the plugs are made of the same the blocks. The method of .g blocks is such that especially or is not required and standard such as screws or nails may iii .tur ance of the surrounding blocks.
valso pointed out that the various terms of anchoring recesses are such that they may be readily formed in the block either by molding or by cutting away the block at the points desired.
While a number of specific embodiments of the invention have been disclosed it is obvious that the above disclosure will sug gest others and it is not desired that the appended claims be limited otherwise t required by the prior art.
