STREET-CURBING BLOCK.

SPECIFICATION forming part of Letters Patent No. 477,721, dated June 28, 1892. Application ad July 16, 1891. Serial No. 399,782. (No model.)

To all whom it may concern:

Be it known that I, SCOTT A. WEBB, a ,citi-.

zen of the United States, residing at Columbus, in the county of Franklin and State of 01110, have invented a certain new and useful Improvement in Street-Curbing Blocks, of

which the following is a "specification.

My Invention relates to the improvement of curbing-blocks of that class which are formed of hard-bu rned clay or other similar substance and which are adapted to have their ends united to form the usual curbing between streets and sidewalks.

The objects of my invention are to provide simple and improved means for forming a firm and reliable connection between the ends of the blocks, and thus retain the same in proper alignment, to form this connection in an inexpensive manner and byits use obviate" the necessity of forming projecting tongues on the ends of the blocks, to provide improved keyways for tar-joints, and to produce other improvements 111 said join ts hereinafter desig-j nated. These objects I accomplish in the manner illustrated in the accompanying drawings, ,m which-- Figure l is a view in perspective of two of my improved curbingblocks united and shown in connection with a portion of a sidewalk. Fig.2 is a central longitudinal section taken through a portion of each of said blocks at the joint. Fig. 3 is a similar view showing a modification in the form of joint block or brick and tar-keyway. Fig. 4 is a View in perspective of one of my improved jointbricks, and Fig. 5 represents a modified form of joint-brick.

Similar letters refer to similar parts throughout the several views. I

a reprepresents the curbing-blocks, which, as described in my former patent, No. 427,648, dated May 13, 1890, are preferably formed of hard-burned clay and are oblong in form, having the desired contour or shape at their up per sides to facilitate the connection of the sidewalk-pavement therewith and to prevent the injurious resultof the contact of vehiclewheels with the same. As shown in the drawings, the surface of the sides and ends of this block are at right angles with each other, except such projections as are formed on the sides of the block at its upper portion. Each of the blocks a has formed longitudinally thereth rough, at the center of the width thereof, two or more channels or openings 1), arranged one above the other, as shown, and in such corresponding position in each of the blocks as to result in the communication of the ends of the channels of each block when said block ends are made to abut against each other.

The mouth of each of the openings 1) is, as shown at 0; made slightly flaring or beveled on its opposite vertical sides, this vertical bevel being united or made continuous by angular vertical grooves c, which extend between said bevels in the end of the block. As shown in the drawings, the upper side of the upper opening I) is preferably arched or curved, and the bevels c of each side of said opening mouth are continued upwardly and inwardly to meet at the center of the upper sidoof said opening month. At the meetingpoint of these two bevels c terminates a vertical groove or way c formed in the end of the block and extending from the upper side thereof.

As shown in Fig. 2 of the drawings, I form in the center of each of the bevels 0 throughout the length thereof a V-shaped notch or incision e in the form of a re-entering angle. As shown in the drawings, the formation of the bevels c and corner notches 6 result when the ends of two blocks are made to abut against each other in the production of a substantially M-shaped recess or tarway.

71 represents oblong bricks or joint-blocks, which, as shown, are substantially in the form of ordinary bricks and which are of such size as to be inserted within the mouths of the openings 1) of the curbing-blocks. Thesejointbricks are preferably provided at the centers of two of their longer sides with oppositelylocated vertical channels 9, which extend throughout the height of the brick. In uniting the curbing-blocks these bricks are, as shown in the drawings, made to extend partly within the passages l) of one block and partly within the corresponding passages of the adjoining blockor are arranged to break joints with said curbing-blocks. In this position the channels 9 of the blocks communicate with the beveled and notched ways 0 e of the channel-mouths. Two of the curbing-blocks having been thus connected or made to adjoin each other, tar or other similar substance is poured into the tarway formed by the uniting of the end grooves 0 said tar passing downward therefrom into the beveled and notched ways c e and brick-channels g, filling the same, and resulting when cool in the formation of tar-keys,whieh will serve to firmly unite the adjoining curbing-blocks and jointbricks together.

As shown in Fig. 3 of the drawings, I may omit the notches 6, simply using the bevels c, and the channels g may be omitted from the bricks. In this case the triangular tar-key formed will by adhering to the side faces of the joint-brick serve as a connection between the curbing-blocks and said brick.

From the construction herein shown and described it will be seen that the joint-bricks will at all times serve to prevent any lateral or vertical displacement of the curbing-blocks and that the latter will be retained in perfect alignment with each other, thus resulting in a continuous line of curbing-blocks having flush surfaces, which will present a neat and substantial appearance.

The tar-keys employed as described will operate not only as binders for the blocks and joint-bricks, but will serve to prevent the entrance of water or moisture at the joints. The form of tarway described and shown in Fig. 2 of the drawings, as will readily be seen, is such as to afford resistance of pressure against the blocks or bricks in any direction and will greatly facilitate the production of a durable and reliable connection of the parts.

As will be seen by the construction shown, the necessity of forming joint projections with the ends of the blocks is obviated and the con-' struetion of the curbing eheapened and sim- Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a street-curbing, the combination, with the blocks to, having their ends abutting, as described, longitudinal channels through said blocks,bevels c at the mouth sides of each of said channels, tarways 0 leading thereto, and bevel-connecting grooves c, of joint-bricks formed separately from said blocks and supported, as described, within the channelmouths of two adjoining blocks, and a filling of tar or similar substance in said Way c ,bevels c, and grooves c, substantially as specified.

2. In a street-curbing, the combination, with the end-abutting blocks a, having longitudinal channels I), bevels c on the mouth-edges of said block-channels, notches 8, formed in said channel-edges at the centers of said bevels, and grooves c in said block ends connecting the bevels c of the various channels, of joint-bricks f, formed separately from said blocks and inclosed partially by the channels of one and partially by the channels of the other of tWo of said abutting blocks, and a filling of tar or other similar substance in said bevels, notches, and grooves,as described, substantially as and for the purpose specified.

3. In a street-curbing, the combination, with the end-abutting blocks 0-, having longitudinal channels I), bevels c on the mouth-edges of said block-channels, notches 0, formed in said channel-edges at the centers of said bevels, and grooves c in said block ends connecting the bevels c of the various channels, of joint-bricks f, formed separately from said blocks and inclosed partially by the channels of one and partially by the channels of the other of two of said abutting blocks, side tar- Ways g in said join t-bricks, as described, and a filling of tar or other similar substance in said bevels,notches, and grooves, as described, substantially as and for the purpose specified.
