STREET-CU RB.

SPECIFICATION forming part of ALetters Patent No. 379,401, dated Marcil 13, 1888.

Application filed June 29, 1887. Serial No. 242,875.

To all whom it may concern,.-

Be it known that I, ABRAHAM B. KoPLIN, of the borough of Hellertown, in the county of 1 Northampton and State of Pennsylvania, have 5 invented a new and useful Improvement in StreetCurbs, of which the following` is a full, clear, and exact description.

This invention consists in a metal curb of novel construction for street-pavements, sub- 1o stantially as hereinafter described,and pointed out in the claims. A

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l represents a view in perspective of two attached sections of a street-curb embody ing my invention and as adapted to a brick pavement. Fig. 2 is a plan of the same as ap- 2o plied to the pavement, and Fig. 8 is avertical transverse section of like parts. Fig. et is a transverse section of a pavement, showing a modified construction of the curb and specialmeans for securing it.

The curb is made of either cast or wrought iron and of a width or depth dependent upon the depth of the gutter, it being designed to project one inch or more below the top of the gutter-Cobble b. It is built up in sections A 3o of any desired length-say ten feet, more or less-and the sections united as by fish-plates c, or otherwise. Said curb is mainly ofdonbleange shape-that is to say, is constructed with an upper appoximately horizontal Bange,

d, and an outer downward Bange, e, arranged to form an obtuse angle with the upper flange. These tlanges extend throughout the length of the curb-sections, the outer one, e, passing below the top of the cobhle of the gutter, and

4o the other flange, d, being on a level with the pavement, or thereabout. When the pavement B is a brick one, as shown in Figs. Zand 3, then I sometimes construct the llange d of the curb, or each curb-section, with angular 4,5 pockets or recesses f, to receive a portion of each outer paving-brick within it. For a stone pavement said iiange d may be made plain along its inner margin. The gutter-flange e is of a diminishing thickness in a downward direction and joins the upper iiange by an interior concave molding.

(No model.)

The sizes and thicknesses of the different parts may be varied to'suit circumstances or different opinions, and accordingly as the curb is made of cast or wrought iron.

As shown in Figs. l and 3, the flange portion e ofthe curb is provided with legs or feet g,which are of sufficient length to project considerably into the ground below the cobblestones of the gutter, and may be made flaring at their lower ends, as shown, to give a more elcient anchoring effect on the curb. In Fig. l these legs or feet g, of which there may be two or more to each section, are shown as cast to or with the curb-sections, and in Fig. 3 they are shown as separately secured thereto by a lap-joint and bolts; but they may be otherwise attached.

Fig. 4 shows the invention as applied to a stone or fiag pavement, B', and with the feet g omitted, in which case tie-rods It are used in place ofthe feet, said rods, of which there may be two to each section, being fastened at their one end to the inside of the curb, and, after passing through the ground beneath the pavement to the bnilding line, being` secured at their other end to the wall C of the building. By means of this metal curb a curb extending the full length ofa block or square may be laid and will be sure to remain in position. It cannot be undermined with water, as in the case of stone curbs, in which latter instance the water soaks down to the bottom of the trench dug for reception ofthe curb and then runs along beneath the curb and saps its foundation, which causes the curb to sink' out of line or position. With my improved curb, however, no trench is necessary, but, at the best, only holes to admitv the legs or feet, and where tie-rods are used instead of legs or feet even these holes are not necessary.

'Ihe improved curb is easy of adjustment, and may be put down at a much less expense than a stone curb.

A brick pavement is less expensive and better with my improved curb than with the or dinary curb, inasmuch as the bricks need not be cut at the outer margin of the pavement to fit the curb by reason ol' the angular pockets or recesses f in the top of the curb, which serve to admit approximately one-half of the several outer bricks within them, as shown in Fio. 2.

ICO

Frost will not affect this curb, because when legs or feet g are used they are planted in sand,

i, as shown in Fig. 3. and When tie-rods h are used they also lie in said sand@l beneath the 5 pavement, and with sand there is no tendency to heave up. Moreover, this curb or curbing is applicable to all climates and much cheaper than a stone one, and When coated with red lead before laying it down it is as durable as a stone curb and can be shipped at less eX- pense. Said curbs, too, present a better appearance and possess great strength, so that there is little 0r no danger of their being broken by the backing of heavily-loaded vehicles I5 against them.

Having thus described my invention, what A. B. KOPLIN.
