FASTENING DEVICE FOR WIRE ROPES.

SPEGIFIGATION formingpart of Letters Patent No. 728,689, dated May 19, 1903. Application filed Octoher'13, 1902. Serial No. 127,139. N m

To ctZl whom it may concern:

Be it known that I, MAX AM ENDE, a subject of the German Emperor, residing at 18 Abingdon street, Westminster, in the county of London, England, have invented certain new and useful Improvements in Fastening Devices for Wire Ropes; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fastening devices for wire ropes.

According to this invention I insert one or more pieces of metal of suitable shape inside a wire rope near the end or at such part where the fastening is to be made in order to thicken the rope at this part. The piece or pieces of metal may be held in position by suitable means, such as a wire wrapping, for instance. I further slip a ferrule of conical or other suitable form onto the rope and drive it tightly onto the thickest part. For greater security I generally drive wire nails into any spaces left between the wires of the rope and the ferrule, and I generally use a second ferrule, with nails behind the wire wrapping, to prevent the latter slipping. This second ferrule may have its rear end brazed or soldered, thus further securing it to the wires and nails. The first ferrule is suitably shaped to enable it to be readily attached to any required body.

In order that my said invention may be clearly understood, I will proceed to describe the same with reference to the drawings accompanying this specification, in which- Figures 1 and 2 show partly-sectional views of one method of carrying out my invention. Figs. 3, 4, 5, and 6 show modified forms of the invention.

In Fig. 1, F shows the ferrule; B, the central bolt. N N show some of the pointed pieces of wire, and W W show the wires of the rope, only the outer ones being shown on the drawings.

Fig. 2 shows the Wire rope provided with a light'wire wrapping it, over which is placed a stronger wire wrapping S, with its continuation T, the latter to prevent the wrappings from slipping upward. The pointed pieces of wire are bent under the wrapping h. V In this way or similarly if the Wires be incased in melted lead, solder, pitch, red lead, putty, or other holding material a bulb is formed in the rope. The thickest part of the bulb is at the top of the ferrule, or thereabout, and some distance higher up the rope has the same thickness as below the ferrule.

I generally leave a space between the wrapping S and the top of the ferrule F. This space is diminished when a heavy weight is suspended from the rope while the ferrule rests on a support.

In Figs. 3 and 4 is shown a second smaller conical ferrule f immediately above the wrappingS in place of the wrapping T. The wires of the rope are securedin this second ferrule fin a similar way to that in which they are secured in the ferrule F. In place of the wrapping S, I may use another ferrule or one or more rings, which I drive down, cold or hot, upon the thickened part of the rope. These rings R R are shown at Fig. 4. b and n it show pieces of metal in ferrule f. (See Fig. 5.)

In Fig. 5 (which is drawn to asmaller scale than that of the other figures) I make a second bulb in the wire rope, the upper part of which projects above the second ferrule f. The second set of pieces of metal or hard substance are shown at b. 1' shows the second ring, and f the third ferrule. Thus I can put a third set (f and b) of parts on the second, and so on. G indicates a support under the ferrule F.

Fig. 6 shows the ferrule F with an upward extension H, by means of which the wire-rope fastening may be attached to a given bodyfor example, to another similar fastening with a ferrule F and an extension H by means of a shackle between the two. The extension H is not a necessary part of the wire-rope fastening, but serves only the purpose afore-v said.

I use the arrangement shown at Fig. 2 on wire ropes of small thickness and made of wires of minor strength. ment shown at Figs. 3, 4; for ropes of ordinary strength and thickness, andI use the arrangement shown at Fig. 5 if the rope is very thick and the wires very strong-for example, in the anchorage of a cable of a suspensionbridge.

I use the arrange-- What I claim as my invention, and desire to secure by Letters Patent, is

1. In a wire-rope fastening, the combination with a mass of metal inserted in the mid dle of the rope, a ferrule forced down over that portion of the rope that incloses said mass of the metal, wire nails driven from the rear of said ferrule in the spaces between the strands of the rope, and a wire Wrapping wound over saidnails and said strands, substantially as and for the purposes described.

2., The combination with a Wire rope, of a conical mass of metal inserted into the center of the rope to form a bulb therein, a ferrule forced down over said bulb, wire nails driven from the rear of said ferrule in the spaces between the strands of the rope, and a wire wrapping wound over said nails and said strands, substantially as and for the purposes described. p

3. The combination-with a-rope and a conical mass of metal inserted in the center thereof, and forming a bulb insaid rope, of a tapering ferrule forced down over said bulb, wire nails driven into the rear of said ferrule in the spaces between the strands of the rope, and a Wire wrapping wound over said nails andsaid strands, substantially as and for the purposes described.

4. A wire rope provided with a plurality of bulbs therein each formed by insertinga mass of metal in the center of the rope, and tapering ferrules forced over said bulbs, with wire nails driven from the rear of the ferrules into the spaces between the strands of rope, substantially as described.

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