Abstract
A conveyor having a series of pans mounted on chain links with the leading and trailing edges of the pans overlapping. The trailing edge of each pan has a stiffened transverse arcuate based contacted by the front corner of a transverse arcuate front bead on the rearwardly adjacent pan under all operating conditions. The shape of the beads causes the front bead to deflect and self bias into contact. End plates are welded to the pan except at the front bead from the leading corner to the peak of the arc of the bead. This leaves the front portion free to flex to develop the bias. The end plates are also shaped to develop bias to maintain line contact of the front edge of the end plate on the rear portion of the end plate next ahead. The plates overlap in all operating conditions.
