ABSTRACT:
A conveyor of the endless chain type passing around two or more sprockets provided with means for compensating for the chordal action which ordinarily occurs as a chain passes around its associated sprocket. The chain is composed of links having overlapping portions pivoted together by pins which have eccentrics associated therewith that have sprocket-engaging surfaces. As the links move onto and off the sprockets, these eccentrics are controlled to rock relative to the pivot pins to vary the pitch of the successive links, which serve to keep the runs of the chain moving at a constant speed.
