## Abstract

A thimble insert for placement in a thimble eye of a cable, the thimble insert including a rigid body having a groove therein for engagement with the thimble and a slot for receipt of an anchor device engaged by the thimble eye. The body can be prepared with either a cylindrical or a tear drop profile and may be fabricated as a two-piece assembly.

## Claims

### Claim 1

A method for inhibiting kinking and twisting of a cable relative to an anchor secured to a cable thimble eye on the cable comprising:
forming an insert for the cable thimble eye, the insert having a cylindrical body with an external diameter incrementally greater than the internal dimensions of the cable thimble eye and a circumferential, thimble-receiving groove in the body, the insert including a radial, anchor-engaging, rectangular slot extending the length of the body;
obtaining a flat anchor having a thickness corresponding to the slot in the insert, the anchor having an aperture in the end thereof to receive the thimble and cable therethrough;
snugly inserting the end of the anchor into the slot in the thimble insert with the aperture in the anchor positioned at the circumferential groove in the insert;
inserting the thimble through the aperture and around the circumferential groove in the insert;
passing an end of the cable through the aperture and around the thimble onto a portion of the cable;
and
securing the cable end to the cable thereby inhibiting kinking and twisting of the cable relative to the anchor.

### Claim 2 (depends on 1)

The method defined in claim 1 wherein the forming step comprises fabricating the insert as mating halves, the halves joining along the center of the circumferential groove.

### Claim 3 (depends on 2)

The method as defined in claim 2 wherein the securing step comprises joining the halves from each side of an assembled thimble eye and anchor.

### Claim 4

A method for inhibiting elongation of a cable thimble when the cable is placed under tension and inhibiting relative kinking between the cable and an anchor when the tension is released comprising:
preparing a cable thimble insert by fabricating a cylindrical body having an external diameter and a length, the external diameter of the body being an incremental distance greater than the internal width of the cable thimble, forming a circumferential groove in the body to matingly receive therein an inner face of a portion of the thimble and cutting a rectangular radial slot into the body, the rectangular slot extending the length of the body and having a width selectively predetermined to engagedly receive the anchor;
obtaining a flat anchor having a thickness corresponding to the width of the slot so as to be snugly received in the slot, the anchor having an aperture in the end thereof to receive the thimble and cable therethrough;
snugly inserting the end of the anchor into the slot in the thimble insert with the aperture in the anchor positioned at the circumferential groove in the insert;
inserting the thimble through the aperture and around the circumferential groove in the insert;
passing an end of the cable through the aperture and around the thimble onto a portion of the cable;
and
securing the cable end to the cable.

### Claim 5 (depends on 4)

The method defined in claim 4 wherein the preparing step further comprises fabricating the body as a first segment and a second segment, the first segment being matingly engageable with the second segment along a line corresponding to the center of the circumferential groove.

### Claim 6 (depends on 5)

The method defined in claim 5 wherein the fabricating step comprises forming a shaft extending from the first segment and a corresponding throughbore in the second segment, the throughbore matingly receiving the shaft.

### Claim 7 (depends on 6)

The method defined in claim 6 wherein the forming step comprises preparing the slot along the shaft and extending the slot through the first body.

### Claim 8 (depends on 2)

The method defined in claim 2 wherein the forming step further comprises preparing the shaft with a key and the throughbore with a corresponding keyway thereby keying the first segment to the second segment.
