## Abstract

The forged chain link assembly comprises a forged chain link having a male end and a female end which cooperates with an opposite end of an adjacent link to form a chain, each end having a bore therein which cooperates with a bore in the opposite end of an adjacent link for receiving a hollow sleeve and bolt assembly therein for creating a forged link chain wherein the links pivot relative to each other, a hollow sleeve of the hollow sleeve and bolt assembly extending through the bores, with a washer of a diameter greater than that of the bore positioned to each lateral side of the female end of a chain link, and an elongate bolt extending through each washer and a bore in the hollow sleeve and receiving a nut thereon, the hollow sleeve having a length which is not equal to a lateral extent of the female end.

## Claims

### Claim 1

A forged chain link assembly comprising a forged chain link having a male end and a female end which cooperates with an opposite end of an adjacent link each end having a bore therein which cooperates with a bore in the opposite end of an adjacent link for receiving a hollow sleeve and bolt assembly therein for creating a forged link chain wherein the links pivot relative to each other, a hollow sleeve of the hollow sleeve and bolt assembly extending through the bores, with a stop member of a diameter greater than that of the bore positioned to each lateral side of the female end of a chain link, and an elongate bolt extending through each stop member and a bore in the hollow sleeve and receiving a nut thereon.

### Claim 2 (depends on 1)

The assembly of claim 1 wherein the hollow sleeve is longer than the lateral extent of the female end.

### Claim 3 (depends on 1)

The assembly of claim 1 wherein the hollow sleeve is slightly shorter than the lateral extent of the female end.

### Claim 4 (depends on 1)

The assembly of claim 1 wherein the hollow sleeve is slightly shorter than the lateral extent of the female end and at least one spacer is positioned within the bore in the female end to either side of the hollow sleeve and extends outwardly of lateral extent of the female end.
