v ROAD MAKING Application filed April 19,
This invention relates generally to road making and particularly to precast curbing units for roads.
In making country roads of concrete it has heretofore been customary to pour the concrete road bed andthereafter to'fill in the-borders or berm of the road with gravel or other filling material. This practice has several disadvantages. The machinery used in excavating and laying roads is necessarily heavy. After a portion of a concrete road some other path than over the concrete. This often necessitates moving a long detour.
Another disadvantage of methods'at present in common use is that they require the use of heavy steel forms. The forms are laid along the edges of the road and the road bed is then poured- After the road bed has set the forms must be removed for further use. The forms are heavy and require a good deal of labor in placing and removing them. Furthermore, they are relatively expensive.
These disadvantages are overcome by my invention in which the curbing units are first laid, and the small amount of berm required is filled in and the main road bed is then laid. The laying of the main road bed completes the road making operation. The precast curbing units are preferably made of vitrified clay, but they may if desired be made of other material such as'concrete. The units are made hollow and are provided with means for interlocking adja-' cent units to maintain them in alinement. In a modified form of the invention, the ends of the units are closed so as to prevent access of moisture thereto. The units are provided with means for tying them to the road material. .In the accompanying drawings which the machinery by 1929. semrnd. 356,353.
illustrate several preferred embodiments of my invention Figure 1 is .a cross-section of the road,
showing the precast units in place,
Figure 2 isa perspective view of one of the units, v 1
Figure 3 is a, plan viewof one of the units, Figure 4 is a section'on the line IVIV ofFigure 3.
'Fig'ure dis a. cross-section through two units showing the means'of locking themf f or maintaining themin alinement.
Figure 6 is similarto Figure l butshowing a modified figure of the unit.
Figure .7 is a sectional viewoffadjacent units having their ends closed inorder to prevent access of moisture. l
Figure 8 is a View similar to Figures 1 and 6 but showing another modified unit, and" Figure 9 is a cross-section of a further modification.
Referring'to Figures 1 to 5, there is shown a road having a bottom layer 2 of earth, and
a top layer 3 of concrete. Precast vitrified clay units A form the side edges of the road.
The-units A are hollow and are of general rectangular shape. Each unit hastop and bottom walls 4 and5, inner and outer side walls'6 and 7 and intermediate partitions 8.
The lower part of'the innerside wall- 6 is formed in a step 9 which when the unit is used 7 in a road, extends under aportion of the concrete 3. The-bottom wall 5 of the unit is provided with ribs 10 extendinglongitudinally-thereof. Similar ribs 11 and 12 are pro-.- vided on the-top surface of the step 9and on the inner side wall 6'; These ribs are'dovetailed so that when the concrete is poured they securely tie the units to the concrete 0f;the
the units in alinem ent. As shown in Figures 1 3 and 4 holes .15 are provided inthe step 9.
for the reception of spikes which :when inserted into the hole and driven into the earth fix theunits in position. The top' wall 4 of the unit slopes, generally downwardly and outwardly, butthe inner edge 16 of the top surface is leveled so as to form a flat surface for the wheels of the finishing machine to run on.
In using the units, they are first laid and interlocked by inserting the projections 13 into openings ll, the berm 17 is then filled in and thereafter the concrete is poured to form the main body of the road. The ribs 11 and 12 interlock the units with the concrete.
The modified form of unit B shown in Figure 6 is similar to the unit A except that a step is not formed on the inner surface of the unit to tie the unit to the road making material. Parts of the unit corresponding to parts previously described are indicated by the same numerals with b sufiixed thereto.
In Figure 7 the ends of the units C are closed by walls 20 which prevent access of moisture to the interior of the units. The construction of the units is otherwise similar to the units A and B. This type of unit is of advantage-where it is likely that Water step and on theupper part of the inner wall of the unit for tying the unit to the road mate rial, the inner portion of the top surface of theunit being level, so asto support the wheels of a finishing machine, the remaining portion of the top surface of the unit sloping form the berm of a" road. In testimony whereof I have hereunto set myhand. v

layer 23. Bricks 24 are layed on the finishing layer 23. The units are tied to the lower 7 layer 22 of concrete by the step and ribs 11d and 1265 as previously described. I
' The unit E shown in Figure 9 is similar to the unit shown in Figure 8 with the exception that it does not have a step provided on the inner surface of the unit for tying the unit and the concrete road bed together.
All'of the units, with the exception of those havingtheir ends closed as illustrated in Figure 7, are adapted for receiving conduits such as electrical conduits thereby avoiding the necessity of using poles which present" an unsightly appearance.
In addition to the advantages already pointed out, the use of precast curbing units in accordance with my invention provides a road the borders of which form smooth surfaces in case the wheels of the'vehicle go as the concrete road bed.
I have illustrated and described several preferred embodiments of my invention. It
-is to he understood however that the invention may be otherwise embodied within the scope of the following claims.
I claim: I
1. A preformed hollow curbing unit having the lower part of its inner wall offset inwardly to form a step, ribs extending longitudinally of the unit on the upper face of downwardly and outwardly to adapt it to the step for tying the unit to the road'mate- 4
