Application filed December 9, 1904. Serial No. 236,132;

To alZ whom, it .may concern.:

Be it known that I, HOWARD B. OURsLER, a citizen of the United States, residing at Pittsburg, in the county of Allegheny, State of-Pennsylvania, have invented certain new and useful Improvements in Structural Street- Curbings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others.

A further object of-the invention is to pro-- vide a structure wherein the said wearing material will be securely anchored or held in place.

Other objects and advantages ofthe invention will be understood from the following description.

In the drawings forming a portion of this specification, and in which like numerals of body during the process of its formation is a structural metal strengthening medium, which serves also to present faces where needed. The structural medium inquestion consists of a channel-iron set into the upper v outer longitudinalcorner of the body 20, with its upper iiange 21 flush with the upper face 22 of the body and its lower flange 23 resting upon the shoulder 24 at the base of the rabbet in which the channel-iron is seated, the web 25 of the channel-iron resting against the vertical face 26 of the rabbet. To hold the channel-iron positively against dislodgment from the body 20, any suitable number of anchors 27 may be passed through the web 25 at intervals and transversely of the body portion ,and

-against longitudinal movement.

then downwardly of the body portion, it being understood, of course, that these anchors in practice have the plastic material molded around them after they have been bent and secured to the channel iron or. beam.' The outer end of each anchor is riveted over against the outer face of the web 25, and the lower end of each anchor is provided with a foot, as illustrated.

In use the curbing is set with the exposed edges of the flanges 21 and 23 toward the roadway, so that they may receive Wear 0f A wheels that would scrape against the curbing,

this channel iron or beam serving also to prevent chipping of the plastic body 20.

In Fig. 2 of the drawings there is sho wn a plastic body lportion 20, having embedded therein two iiat plates 21 and 22', of which the plate 21 is set in the upper face of the body 20' and extends from end to end thereof and substantially half-way of its width, although the width of the plate, as well as its thickness, may be varied asdesired to satisfy different specific conditions. The upper face of the plate 21 is Hush with the upper face of the plastic body at the side thereof, and one longitudinal edge ofthe plate 21 forms an upper longitudinal corner of the curbingwith its side face projecting beyond the corresponding side of the body 20. The plate 22 is embedded in the material of the body 20 below and parallel with the plate 21 and with one longitudinal edge in the same planewith the exposed longitudinal edge of the plate 21. The plate 22 is illustrated as of the same width as the plate 21; but the dimensions of the plate 22 may be variedy as desired. Through the plates 21 and 22 at intervals are passed anchors in the form of bars 23, which may be riveted over upon the plate 21 or secured thereto, as well as to the plate 22', in

any other suitablemanner, the bars extending below the plate 22 and into the body 20 and having concavities 24 in its side faces, into which the plastic material of the body 20 will iiow to hold the anchors or ties By reason of the fact that the plates 21 and 22 project slightly beyond the exposed face of the body portion 20 theyfreceive the rub of vehiclewheels that would otherwise strike the relatively soft face of the plastic body. The ex-4 posed end corners of, the plates 21 and 22 are rounded, as illustrated, so as to deiiect the Vehicle-Wheels that might behalted in striking tions projecting through a vertical face of the exposed end portions of the plates if they the body and an anchor connected with the -Were square.
