Abstract

An improved connector for coupling a chain to a wire rope or cable such that the resulting connection can be passed over a sheave, pulley, wheel or windlass without excessive stress applied to the wire rope. A housing is provided having an axially symmetric opening through the housing with an exterior surface adapted to rest upon the outer peripherial portion of the windlass (or the like) as the connection traverses the windlass and wherein a retaining pin perpendicular to the axis of the opening at essentially the center of the housing holds a pair of rotatable U-shaped members within the housing for connecting the chain to the wire rope. Such a connection is particularly useful in coupling an anchor chain to a wire rope in anchoring systems.

Claims

1. A connector for coupling a chain to a wire rope comprising:

a housing having an axially symmetric opening through said housing and an exterior surface circularly concentric to said opening;

a retaining pin adapted to mount within said housing such that said pin perpendicularly intersects the longitudinal axis of said opening at essentially the center of said housing;

a pair of substantially U-shaped members capable of being assembled within said opening of said housing and said U-shaped members having openings at the end of each arm of said U-shaped members such as to interact, when assembled, with each other so that the openings will be coaxial and will accept said retaining pin; and

a means to maintain said U-shaped members, pin and housing in an assembled state.

2. A connector of claim 1 wherein said exterior surface of said housing is essentially spherical.

3. A connector of claims 1 or 2 wherein said exterior surface of said housing is adapted to rest on an outer peripheral portion of a wheel employed to guide said chain and wire rope such that said wire rope does not experience excessive strain as said connector passes over said wheel.

4. A connector of claim 1 or 2 wherein said axially symmetric opening is adapted to allow significant angular deviation from and about the axis for both said chain and wire rope.

5. A connector of claim 1 or 2 further comprising;

a circular groove within said housing adapted to allow said retaining pin to rotate with said circularly concentric opening.
