Abstract
A hook line includes a hook portion and a link portion contained in two different planes substantially perpendicular to one another. A projection tip is provided on a distal end of the hook portion to provide secure locking action between adjacent hook links; the normal clearance between the tip and the connected link portion being insufficient to allow coupling/uncoupling action. A tip receiving groove extends substantially laterally across the elongated ring forming the link portion. The ring defines a longitudinal slot for receipt of said hook portion. The groove of one hook link receives the projection tip of an adjacent hook link to allow coupling/uncoupling action. In the preferred embodiment, the groove extends along an arc between a transverse midline of said longitudinal slot and an end of said longitudinal slot opposite said hook portion. The groove and tip structure substantially eliminates uncoupling during normal conveyor operation even when subjected to incidental slackening. The link portion may additionally be provided with a paddle mounting bracket for mounting a reversible/replaceable conveyor paddle and wear shoe.
