PAVEM ENT-CU RB.

SPECIFICATION formng part of Letters Patent No. 431,898, dated. July 8, 1890.

Application filed November 6 1889. Serial No. 329,&01. (No model.)

To all whom it may concern:

Be it known that I, ISRAEL L. LANDIS, a citizen of the United States, 'esding at Lancaster, in the county of Lancaster and State ot' Pen nsylvania, have invented certain new and useful Improvements in Pavement-Curbs, of which the following is a specifioation, referencebeing had therein to the accompanying drawings, in which- Figure l represents a transverse sectional View of a portion of a sidewalk and the adjacent gutter, showing one form of my improved curbing; Fig. 2, a similar View showing another form of my improved metallic curbpFig. 3, a perspective view of another form of curbing attached to its adjacent block; Fg. 4, aplan view showing the method of setting the curbs and their blocks; and Fgs. 5, 6, and 7, views of slight modifications of the invention, which will be herenatter described.

The design of the present invention is to provide an extremely cheap and durable metallic curbing for pavements construeted of artificial-stone blocks, concrete, asphalt, cement, or other composition usually formed into blocks while in a plastic state; and it consists in certain novel features, which will bc fully hereinafter pointed out and claimed.

In the drawings, a designates the concrete, cement, artificial stone, or other composition blocks which bordel' the outer edge of the pavement, and to which are secured the vertical eurb-plates b. These plates are any suitable thickness and width, their lower edges extending into the earth a suitable distanoc to assist in anchoring them. The eurbplates are attached to the ont-er edges of the stones by means of horizontal bolts b' ,which extend back into and are embedded in the body of the adjoining stone, the heads of these bolts being countersnnk into the face of the curb and their rea-r ends being provided with projections b", to prevent their withdrawal. To prevent the curb-plates settling too much, they may be provided with foot-pieces b', as shown in Fig. 1.

As shown in Figs. 2 and 7, I may provide the npper edges of the plates b with horizontal inwardly-turned flanges c, which may be embedded in the bloeks to bring them fiush i with the sidewalk. Angle-irons d, as shown in the same figures, may, if desi'ed, be bolted to the cnrb-plates to assist in supporting the pavenent-block a.

In addition to or inlieu of the above means for securing the face or curb plates to their adjoining blocks, I may bend the ends of the plates inwardly and embed them in the sides of the blocks, as shown in Figs. 3, 4, 5, and 6.

In setting these curbs I preferably employ the means shown in Fig. e-that is to say, I take a bean or straight-edge fand hold the curb-plates in perfect alignment with each other while the compositionis being filled and paeked in back of the plates, the straightedge being allowed to remain in position until the blocks harden and set. It is evident that one curb-plate may be employed for each block, as shown in Figs. 3 and 4, or long cnrbs employed, to which may be attached any number of blocks as the exigencies of the case may reqnire. The heads ot' the rods b' may be screwed into the plates b, or they may be riveted thereto and their struck-up heads countersunk.

To keep thehlocks (c and curbs b in alignment and break the joints between the blocks, the plates b may be provided with overlapping extensions e' ,as shown in Fig. 5.

Instead of the rods b', I may employ an angle-iron a", as shown in Fig. 7, and bolt or rivet the same to the inner side of the curb.

The inner ends of the rods b' may be bent into a hook and hooked over rods a' embedded in the blocks, as shown in Fig. `B, if desired, without departing from the invention.

Having thus fully described my invention, what I claim is-- The combination, with a composition block a, of a metallie curb-plate b, having a fiange c and Secured on the face of the said block and extending down into the earth below the same, a rod Secured to the curh-plate and entering the composition block, and an angleiron d, secured to the back of the said curbplate and adapted to support the said block, substantially as hcrein described.

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

ISRAEL L. LANDIS.
