IMPROVEMENT IN SP'LICES FOR WIRE ROPES.

Speciiication forming part of Letters Patent No. 219,860, dated September 23, 1879; application filed May 21, 1879. l g

To all whom tt may con-cem:

Be it known that I, WILLIAM P. HEALEY, ot' New Orleans, State of Louisiana, 'have invented a new and ,useful or Improved Splice for Wire Rope, of which the following is a specification.

The object of my invention is to furnish a durable splice in wirerope by the use of a fusible metal forvfastening the parts, thereby obviatin g the complicated or repeated tuckin g of the strands, the hemp heart being removed at the splice and the rope kept expanded by inserting short sections of metal tubes opposite the endsjof the molds' into which such fusible metal is poured. In splicing large rope two of the strands may be tucked through the standing part of the rope for the purpose of bringing the strands in better posi-tion for tapering, the other wires being cut oii' atdifferent lengths and fastened down along the standing part by winding with a wire.

In forming the short or end-to-end splice, the strands only are unlaid from the rope, the wi'res of the strands not being unlaid,' the strands of the two parts being crotched together without tucking. The strands `-are then wound or woolded with a wire. And inA forming theend-seizing splice the end of the rope may be merely turned up and stopped with a wire alongside the standing part of the rope, without taperingthe end of the turned-in part.

When the rope is prepared in any of the described or other methods, the spliee'is placed in a suitable mold and the melted metal poured therein, which penetrates the interstices between the wires, and also forms a, coating or sleeve around the body ofthe rope.

Figure 1 is a planview of a section of rope, showing the method of interlocking or tucking the wires through the body of the standing part when making an eyelsplice in large ropes. Fig. 2 is also a plan view of the rope, and of one halt' of the mold in position upon the rope, as when the metal vis applied therein. Fig. 3

is a plan showing the rope with the completed splice. Fig. 4:,is a longitudinal section ot' the rope and completed splice, and showing the hempen core where itis not removed, and the applied metal in place of the hemp core where the same has been removed, and also showing the sections of tubing as inserted to keep the rope expanded. Fig. o is an enlarged transverse section taken on line yz, Fig. 3, and showing the applied metal within the interstices of the wires and-strands, which latter are shown in black. Fig. 6 is a modification, showing the rope in plan, with an end on splice, the applied metal and the mold being shown in longitudinal section. Fig. 7 is also a modification, showing an eye-splice formed without tapering the turned-in part, the rope being shown in plan,and the applied metal in longitudinal section.`

In these figures, A is the standing part of the rope, and A the turned-in part. B is the mold, and G the soft metal as applied to the rope in the mold.

a represents a strand as tucked through the body of the standing'part when large ropes are spliced by my method.

b b are the unlaid wires, which are cut at 'varying lengths when it is desired to form a tapering splice. y

c is the woolding, which is temporarily applied to hold the parts in position while the' strands are being adjusted Vand the wire h is being wound in place. y

d represents the hemp core in the rope, and g is the metal which fills the space where the core has been removed.

fis the gate through which the metal, C, is poure'd to the rope in the mold, and e e are the sections of tubing that hold the strands apart after the core is removed.

In said Figs. 1, 2, 3, 4 the rope is shown with an eye-splice gradually tapered down to the size of the rope. In Fig. 6 both parts of the mold are shown, the section. being taken transversely to the line between such parts. In Fig. 7 an eye-splice is shown formed without being either interlocked or tapered.

Various kinds of soft metal may be employed in forming my splice, such as brass, Babbitt metal, and other mixtures; yet I deem what is known to the trade as Babbitt metal equal, if not superior, to any other for 'such purpose.

The adhesion of the fused metal to the wires, as well as the close contact of the outer body, C, of such metal to all the inequalities of the several strands, and the connection of such body C with the heart gA by means' of /the metal between the wires and strands, is such that by actual tensile test the best wire rope will part at other points than in the splice so made. My splice is also compact, indestructible, and does not injure hemp or Manila rigging when rendered across it besides, this splice can be made by any one, though not a competent and skillful rigger.

I claim as my invention- 1. In a Wire-rope splice, the sections e, to hold the strands of the rope expanded Where the hemp cored is removed, to allow the metal g to fill such space, substantially as specified.

2. The process hereinbefore described of splicing a Wire rope, the same consisting in the formation of a longitudinal cavity in the center of the rope hy the removal of its hem pen core, and casting, by means of a suitable mold, about the ends to be united, and in the cavity x in each, molten fusible metal, so as to form a sleeve around the splice, the metal Within said
