ABSTRACT:
A conveyor system in which carriers are normally towed along the center line by pushers on a power chain that engage center tow pins along the center line of the carriers but which are disengaged from the center tow pins prior to a turn to the right or left to provide a power released carrier. Then the pushers subsequently engage side tow pins along the side of the carrier towards which the turn is to be made to move the carrier around the turn. A positioning take-up device for the power chain is provided to vary the spacing between the carriers by varying the point of engagement of the pushers with the side tow pins.
