To all whom 'it may concern..-

Be it known that I, JOHN D. DAvIs, a citizen of the United States of America, residing at Wilmington, in the coun-ty'of New Castle and State of Delaware, have invented certain new and useful Improvements'in Coping, of whlch the following is a specification.

T his invention relates to an improved metalllc coping for general'use.

T he object of the invention is to provide a coping constructed of casin g or metallic plates `suitably secured together to form a hollow interior which may be filled other suitable material.

A further object is to combine simplicity 1of construction with cheapness in manufacure. For a full and c lea'r understanding of my lnvention reference is to be had tothe accompanylng drawings,"wherein corresponding letters lndicate likev parts in the several views, and in which v Figure 1,` is a perspective view of two sect1o ns forming a corner of the coping, parts belng broken away for better illustration. Fig. 2, represents a cross-section of the copingZ talren on the line :2c-m Fig. 1. Fig. 3, is a view 1n elevation of one of the rests or supports used for the support of one of the ends of a section of coping. Fig. 4, is a detail of a plate or tie bland by means of which lthe ends of two sections are secured together and with Acement or the joint on the top plate of the coping is protected.

In the drawings, A refers to the coping.

B 1s a top plate of the coping, preferably of V shape in cross-section to prevent foreign material from lodging on top of the coping, see Fig. 2.

C. C', are rectangular shaped metallic plates of u nequal width' which form the sides ofthe coping. v

The top plate of the coping has .enlarged portions or rims b on its sidesand depending plates b on its under side near its edges, between which and the rims the upper ends of plates C and C are secured by bolts or otherwise. rApertures 4are formed in the upper i ends of the plates C and C and underneath the rims b, so that when the plates v are to be secured to the top plate, these apertures will register with apertures in the depending plates b in vorder that bolts b2 provided with nuts on their ends may be used to secure the side plates to the top plate,.as

shown. Plate C has its lower side edge bent inwardly to form a rest c2 upon which one edge d2 of the bottom plate D may' rest and through which and rest c2 suitable bolts may pass to secure these plates together.

As preferably constructed, a cross-section of the coping would be of the form of a trapezoid. This particular form or shape of construction is found to be of greater utility and less expensive on account of the slope of the land where coping is usually erected.

- f E are rests upon which the ends of sections of the coping are supported. These rests consist of two rods F F of unequal length, pointed at their lower ends so that they may be readily inserted in the ground, and an upper inclined cross-piece E which connects the rods F F at points near their upper ends leaving' upper projection e and/e above the cross-piece, as shown, to form a support for the ends of the coping to rest upon when said rests are driven into the ground, the incline of the cross-piece E to the rods F F corresponding to the incline of the bottom of the coping to its sides. v A

When the surface of the groundvis smooth and the rests are well driven into the ground, the bottom'pieces D of the coping may be dispensed with, as the ground itself may serve as a suiicient base for the coping upon which the cement or other similar; material may rest when it is inserted in the interior of the coping. G are inwardly inclined projections or ribs on the interior of the plates C C.

- When the bottom plates D are dispensed with and cement is used for the interior, the coping casing, after the plates have been bolted together, is inverted, bottom upward, and the cement is tilled inthe interior of the casing and allowed to set and harden, after which the coping is ready to be set up, the ribs on the interior of the side plates about which the cement has hardened preventing the cement from falling out of the casing in case the ground on which the casing is erected should be uneven or should settle at any time. Tie bands G made of thin strips of metal, having depending ends g and apertures g' in IOO the middle portions thereof, are placed over the joints on the top of the casing which are formed by abutting end sections, and a pin g2 passes through aperture g in the band, through the joint which may be enlarged at this point, and through corresponding apertures in the bottom plates D, should the latter plates be used, and is then driven into the ground to hold the bands as well as the sections in place. Tie bands H having depending ends h' of similar construction to bands G' are likewise used for the corners of the coping, see Fig. 1.

The wider or narrower sides of the coping may be used outwardly depending upon the slope of the land where the coping is placed.

I-Iaving thus described my invention, what I claim is- 1. The combination in a coping comprising rectangular shaped metallic plates bolted to gether at their contacting edges, side plates of unequal width and parallel, rims on the side edges of the top plates, and plates de pending from the top plate near said rims, means to secure the upper edges of the side plates between the rims and depending plates, rests having rods of unequal length sharpj ened at their lower ends, and connected near their upper ends by cross-pieces, tie bands and pins to secure the abutting ends `ot the 3o sections of the coping-together and to protect the joints in the upper surface of the coping, and cement forming the interior of the coping, substantially as described and set forth.

2. The combination in a coping, of rectangular shaped metallic plates secured together at their contacting edges, side plates of unequal Width and parallel, ribs on the interior surfaces of the side plates, rims on the side edges of the top plates and plates depending from the top plates, near said rims, means to secure the plates of the casing together near their contacting edges, rests having rods of unequal length sharpened at their lower ends, cross-pieces connecting the rods near their upper ends, tie bands, and means to secure the same over the joints on the upper surface of the coping, and a plastic material forming the interior of the coping, as and for the purposes set forth.

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

JOHN D. DAVIS.
