ABSTRACT:
A link chain, particularly for use as an anchor chain, comprises a plurality of links joined together in sequence, each link including a closed member comprising a pair of facing U-shaped portions, the base of the U at each end of the member having a portion of its inside surface of part cylindrical form, the cylindrical axes of said portions being arranged substantially transversely with one convex and the other concave so that the part cylindrical convex surface of one end of one link mates with one part cylindrical concave surface at the other end of a preceding link when the chain is straight under tension, and enables the chain to withstand greater loads, the U-ends being shaped to permit relative pivoting of the links about an axis substantially transverse to the plane of the link.
