METALLIQ GURBING.v

i SPECIFICATION forming part of Letters Patent No. 537,04??` dated. April 9, i895.

,Tda/ZZ'whom it/mayorwerm Beit known that I, IsRAELL. LANDIs,a citi'- zen of the'United States, residing at Chicago,

in the county of Cook and State of Illinois,

have invented certan new and useful Improve-v ments in Metallic Curbing, of which the followngis a specification, reference being had therein to the accompanying drawings; in which- Figure lis a sectional perspective Vview showing myimproved' metallic curb applied to a stone pavement. Fig. 2 is a detail sectional view of a slight modification. Figs. 3 and 4 are modifications showing the stone 'pavement recessed to receive the curb; and

Fig. A5 shows my curb secured to a cement pavement. Figs. 6 and 7 show modifications of the fastening devices; and Fig. 8 shows means for covering a break in a curb, or flagstone.

This invention relates to a new and useful improvement in metallic curbs; and it has for itsobjects to provide a curbing of simple and durable construction, which may be secured to a stone curb, or tothe outer edge of the flags of a stone pavement, or to the outer edge of la-cement pavement.

In the drawings 1, designates the sidewalk or pavement which is shown constructed ot' large stones or flags. To the outer upper cor-` ners ot' these stones is secured the metallic curb 2. This metallic curb consists of an angle plate, having the horizontal flange 3, and the downwardly extending vertical flange 4; these flanges fitting closely against the stones of the pavement, and embracing their upper corner as shown. of any suitable size shape, and thickness, and the vertical ange4 may be made to entirely cover the outer face of the stone curbing, or of the stone forming the pavement, if desired. The flanges 3 and 4 of the plate 2 are slightly tapered from where they join to within a short distance ot' their outer ends,

where they are tapered abruptly inwardly tov a knife edge, as shown clearly in Fig. 1.- The object ot' this knife-edge on theghorizontal flange 3, is that the dirt on the pavement may be easily swept over the c urb. Another tdvantage is that there are no sharp corners or the upper side of the curb to cause pedestrians to stumble.

only, and in place of These plates may be made The curb4 2 is secured to the stones of the sidewalk or to the stone curbing by bolts or screws 5 which pass through perforations in llanges 3 and 4 and intoy recesses or pockets 6 formed in the stones. These pockets are filled with lead or cement, which, when-it hardens securely holds the screws or bolts therein', or the holes are lilled with wood. The heads of these bolts may be counter-sunk in the curb as shown for obvious reasons.

' In Fig. 2 is shown a modified form of the curb. In this construction the flanges 3 ,and 4 are shown ytapering on their outer surfaces from their point of connection to their outer edges, the knife-edge being formed by a gradual incline as shown. i

In Fig. 3 I have shown the stones of the pavement recessed at their outer upper corner, andan angle plate set in saidirece'ss, the outer surface of the plate or curb being flush with the outer surface of the stones of the sidewalk. It desired, the metallic curbs may be secured to the stones of the sidewalk as shown in this ligure, that is, a bolt having a counter-sunk head may be passed through the horizontal flange 3 and through an aperture ,in the stone of the sidewalk, and a nut and washer secured on its lower end.

As shown in Fig. 4 the flagfstones of the sidewalk may be recessed on their outer sides the counter-sunk head the bolts may be provided with a square head, and a washer 7 having a recess for the head of the bolt, and downwardly and outwardly incline`d sides may be used as shown, to protect the`head of the bolt.

In Fig. 5 I have shown a metallic strip or curb secured to the upper edge of the outer face ot a cement or artitieial-stone pavement. In this construction, I pass a long bolt horizontally through the metallic strip and into the cement, and secure to its inner end an anchor plate and nut, as shown, which when the cement or artiticial-stcne pavement hardens,securely holds the curb in place, The outer surface of the curb is flush with the outer face of the pavement, as shown. This metallic curb is durable and neat inrappearance. It will ettectually prevent the breaking and chipping of the outer edges of stone sidewalks by the backing of heavily loaded vehicles against them. llt is easily and read- IOC ily secured to the flag stonesalready in place, or it may be secured to them placed in the sidewalk, with equal facility.

In Figs. 6 and 7 are shown modified forms of the fastening device used in securing the metallic curbing in place.

In Fig. 6 is shown an expansion bolt 8, which when in position binds against the sides of the recess 6, securely holding the curb in its place without the necessity of fil1 ing the recess 6, with lead or cement or other suitable material.

In Fig. 7 is shown a bolt 9, having a split end. A wedge l0 is placed at the bottom of the recess G. The bolt 10 is passed through an aperture in the curbing 2, and into the recess 6, and is then driven on to the wedge 10 which expands the split end of the bolt causing it to bind against the sides of recess 6, securely fastening the curbing in its piace. If desired the recess may be filled with cement to more securely hold bolts 8 and 9 in place, as is evident.

In Fig. 8, is shown means for covering the face ofa broken Hag-stone, or curb. As shown, I employ a channel-iron of s uitablesize to snugly fit the face of the broken curb or flagstone and secure it theretoV over the broken portion by any of the fastening devices heretofore described, and fill the recess made by the break with cement, the lower flange of before they are the channel-iron serving as a support fortho cement filling.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In combination with the lflag-stones of a sidewalk, a metallic curbing consisting of an angle plate adapted to it'over the upperouter corner of the flag-stones, the flange of said angle-plate which rests on the upper surface of the stone being tapered to a thin edge, at its outer edge, and suitable fastening devices, substantially as described.

' 2. In combination with the flag-stones of a sidewalk said flag-stones being provided with recessesas described, a metallic curbing consisting of an angle plate adapted to fit over the outer upper corner of said flag-stone, the flange of said angle plate being tapered to a knife edge at its outer edge, devices passing through the anges of said angle curbing and into the recesses in the flag-stones and secured therein by lead or cement, substantially as described.

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