2 Claims. 1..

Thisinvention relatesitoponcrete curbingand more particularly to curb blocks composed of concrete and made in cast sections which are fitted end to end.

A primary object of the present invention is to provide a concrete block with means for fastening it securely to its foundation or support.

Another object is to provide such a block with means for readily and effectively interlocking and aligning it with its adjacent block or blocks and interlocking said block with its support.

Still another object is to provide means for preventing the blocks from becoming displaced on the foundation.

Yet another object is to provide a block of this character that is simple and durable in construction and economical to manufacture.

Other objects and advantages of the improved block will be apparent from the description thereof to follow taken in connection with the accompanying drawing in which- Figure 1 is a perspective View of a block embodying my invention.

Figure 2 is another perspective View of the block from a different View point.

Figure 3 is a bottom plan view thereof.

Figure 4 is a sectional view taken on the plane of the line 4 4 of Figure 6 showing the improved blocks in position upon a concrete foundation.

Figure 5 is a sectional view taken on the plane of the line 5-5 of Figure 6.

Figure 6 is a sectional view taken on the plane of the line 6-6 of Figure 4 showing the relation of the block to the foundation and side walk.

My improved block I is molded from concrete and is substantially rectangular in shape and may be of any suitable length. The block has a front surface including a lower portion 2, a rear surface 3 and end surfaces 4. The front surface portion 2 terminates at the top in an inwardly and upwardly slanting upper portion 5 forming an exposed corner 6 which is set back from the edge of the pavement or foundation l. The front surface 2 slopes inwardly from the bottom of the block to said corner 6 to such an extent as to reduce the possibility of such corner being struck by the wheels of a vehicle. The widely obtuse angular relation of the surfaces 5 and 2 to each other and of the surface portion 5 to the top surface, reduces the possibility of breaking of the corners of the block and of injury to automobile tires by said corners. The rear surface is adapted to form an abutment and support to the sidewalk material 8 as shown in Figure 6.

At each enif .thefblpdi@ns1-.centrallythereof is a molded recess 9; 'said recess' extending from the bottom of the block upwardly to a point substantially on a line with the lower edge of the slanting portion 5 and extending inwardly from the end surface a considerable distance. It will be observed that the recess extends inwardly of the block a distance greater than the width of the recess which is substantially less than the width of the block.

The blocks are to be laid on a previously prepared surface such as the concrete foundation or pavement l while the concrete is still wet.

Each recess 9 is substantially filled and the end walls 4 are covered with mortar lll. The block is pressed downwardly into the wet concrete of the pavement or foundation to embed it into said concrete whereby the mortar oozes upwardly a short distance into the recesses 9 as indicated at ll. The end walls of the adjacent block is similarly covered with mortar and its recesses 9 filled with the same. This adjacent block is similarly embedded into the concrete of the foundation and forced endwise into fitting or contacting engagement with the adjacent end wall of the adjacent block whereby the mortar between the contacting end walls is forced laterally into the recesses. Thus a bonding connection is formed between the mortar and the concrete of the foundation, such bonding connection being in the shape of a cross in horizontal cross section and inverted T-shaped in horizontal Vertical section, as shown in Figure 5. This bonding connection securely anchors the blocks in place on the foundation and prevents lateral and longitudinal displacement of said blocks.

Since the blocks are accurately aligned, the inclined front wall slanting portions are uniformly coplanar and. present a continuous unbroken surface which offers no projections against which vehicle wheels may catch.

The recesses 9 in the bottom of the block are protected and there are no openings in the top of the block that are liable to weaken the block at this Ypoint and permit the mortar or other binding agent to become dislodged.

The simplicity of the form of the block as a whole facilitates the molding operation and enables the blocks to be manufactured quickly and at a low cost.

What I claim is:

1. A concrete curbing construction for highways and the like, comprising in combination, a concrete foundation, a number of concrete blocks each having front, rear, top, bottom and end surand extending inwardly of the body a distance faces and having recesses opening through said greater than the width of the recess which is bottom and end surfaces, said blocks being ar- Substantially less than the width of the block. ranged end to end on said foundation with por- EMIL C.
