Abstract
A conveyor chain having links joined by link pin biased into any of multiple operating positions with its positioning head blocked against rotation by engagement with a detent on a positioning link. The pin can be lifted so that its head is above the level of the detent, rotated to a new operating position, and allowed to be biased back into its position with the head again blocked against rotation by the detent, whereby the wear surface of the pin can be changed to accommodate for chain wear occurring when a link rotates relative to the link pin.
