Abstract

An insert assembly adapted to be received within a link of a chain including a plurality of round wire interlocking links, the insert being made of a resilient material and being dimensioned to be wider than the central area height and longer than the central area depth so that after the insert is placed between the opposed sides of the chain, the insert springs back around the opposed sides of the chain so that the insert is securely locked between the opposed sides of the chain. The insert has a central opening, and the insert assembly further includes a pin secured in the opening when the insert is received in the chain central area so that the insert cannot move away from the chain opposed sides.

Claims (5)

1. An insert assembly adapted to be received within a link of a chain including a plurality of round wire interlocking links, each link having a central area and opposed sides, said central area having a height and a depth defined by said opposed sides, said insert assembly including an insert having a central area having a front and an opposed back, a top and an opposed bottom,

the insert from top to bottom being dimensioned to be wider than the central area height and from front to back being longer than the central area depth so that after the insert is placed between the opposed sides of the chain, the insert is around the opposed sides of the chain so that the insert is securely locked between the opposed sides of the chain,

said insert having a central opening extending from said front to said back, and said insert assembly including a pin secured in said opening when said insert is received in said chain central area so that said insert cannot move away from said chain opposed sides, wherein said central opening is a slot extending from the front of the insert to about two-thirds of the way along the insert to the back of the insert.

2. An insert assembly according to claim 1 wherein said insert is C shaped, the insert back acting as a hinge that permits said top and bottom adjacent said insert front to be brought toward each other to reduce the height of the insert.

3. An insert assembly according to claim 2 wherein the insert back has a hole extending there through.
