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 applying a bending stress to the wire rope. The connector comprises a hemispherical housing having an opening therethrough that is axially symmetric about the radius that is perpendicular to the planar portion of the hemispherical housing. The opening is adapted to accept and retain a wire rope having a terminal fitting by holding the terminal fitting within the hemispherical housing. A semi-circular member of common radius to the hemispherical housing and adapted to accept and retain a chain is attached to the planar portion of the hemispherical housing. A pair of retaining pins pass through the co-axial openings in the hemispherical housing and the end of the semi-circular member terminating on flat surfaces on opposite sides of the terminal fitting of the wire rope. In this manner the essentially spherical connector is held in an assembled state with the wire rope being rigidly affixed within the connector. Such a connector is useful in eliminating bending stress at the wire rope connector as it passes over a sheave or the like and also allows for smaller and more economical sheaves to be employed.
