CURBIN G.

Specification of Letters Patent.

Patented Oct. 1, 1907.

To all whom it may concern:

Be it known that I, SOLOMON W. LERCI-I, a citizen of the United States, residing at Manasquan, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements in Curbing, of which the following is a specification.

My invention relates to improvements in curbing, and refers more particularly to a curbing made of artificial stone blocks, molded into the desired form from concrete or other materials; and the object of my invention is the provision of a simple and substantial form of curbing having a broad supporting base to provide a good solid foundation to prevent the curbing from being forced outward by the pressure'from the sidewalk.

Another object of my invention is to provide satisfactory means for bonding the curb blocks together so as to keep the curbing in proper alinement.

With these and other objects in view, my invention consists of a curbing composed of blocks having an angular foot at the base thereof to provide a broad foundation, and also of means for bonding the meeting ends of the blocks together; and the invention further embraces certain other novel features of construction and combination of parts substantially as herein disclosed and as illustrated in the accompanying drawings, in which:

Figure 1, is a perspective view of two of my improved curbing units, showing the manner in which the ends are bonded. Fig. 2, is a cross sectional view of the curbing showing its relation to the sidewalk and street. Fig. 3, is a top plan view of the corner construction of the curbing. Fig. 4, is a perspective view of a modified form of segment or corner block. Fig. 5, is a detail view of a modified form of bonding connection. Fig. 6, is a transverse sectional view of a modified form of the curb having depressions formed in the walls thereof so as to secure a firm anchorage when set in position. Fig. 7, is a similar view of another modification in which the block is formed with a shoulder in the upper edge thereof to receive the edge of a flagstone or similar pavement.

The blocks or units constituting the curbing are preferably formed of plastic concrete material molded, and each block is formed with an up-standing or retaining wall portion 1, adapted to form an abutment and support to the sidewalk material 2, as shown in Fig. 2, and the blocks are further provided with an out-standing angular foot or foundation '3, this foundation portion being generally covered by the pavement material 4, the general location and arrangement of the street, sidewalk and curbing being illustrated in Fig. 2. The angular foot forms a brace to prevent the upper portion of the curb from being forced outward, and the paving material engaging the upper convex face 5, of the foot, securely anchors the curb block in place.

To prevent longitudinal displacement of the adjoining ends of the blocks, bonding grooves 6, are molded in the ends of the blocks which extend nearly to the lower edge thereof. These grooves are preferably semi-circular or V in shape so as to form a complete circular or angular opening when the blocks are assembled, which opening is filled with mortar or a suitable key as indicated at 7. These bonding openings may be long or short to suit different conditions, the two different conditions being shown in Figs. 1 and 4. Openings 8, may be formed in the wall of the curb block to afford holds to facilitate the handling of the same.

The corners of the curbing are formed by the curved segment blocks 9, these blocks being of any suitable radius, or if so desired, the straight curb blocks are formed with a curved extension on the end thereof, this idea being shown in Fig. 4.

I11 order to more firmly anchor the blocks in place, grooves or channels 11, may be formed longitudinally in the base and inner wall of the block, which grooves form a bonding connection with the filling material of the sidewalk and street pavement.

In order to form a neat and close joint between the fiagstones or sidewalk proper, the inner upper edge of the curb may be shouldered as at 12 in Fig. 7, to receive the edge of the flagstone 14. I

From the foregoing description taken in connection with the drawings, the many advantages and general usefulness and serviceability of my curbing will be readily apparent and it will be further evident that I have accomplished all the results herein set forth as the I claim:

1. A curb block having an upstanding retaining wall portion and an angular foot extension disposed at right angles to the body of the block, half round vertical bonding grooves in the ends of the block, and hand hold openings formed in the face of the block.

2. A curl) block comprising a flat base portion and a retaining wall portion at one edge .thereof upstanding at right angles therefrom, thebase and wall provided with recesses therein to form bonding connection with the tilling material of the street and curl).

3. A curb block comprising a fiat base portion and a retaining wall portion upstanding from one edge thereof, the base and wall provided with recesses therein to form bonding connection with the material of the street and curb, the ends of the block provided with vertical bonding grooves and the face of the block having hand held openings therein.

In testimony whereof I aflix my signature in presence of two witnesses.

. SOLOMON W. LERCH.
