ABSTRACT:
An improvement in a conveyor system having sets of laterally spaced drive and idler wheels, a plurality of at least two different size carriers for containing articles to be worked on and for operating on the same conveyor system; and two runners attached to the sides of each carrier, one runner on each side thereof, each runner having at least one riding surface for supporting the carrier on the wheels, the runners of each carrier being attached and sized and shaped in such manner as to effectuate such support, whereby two different size of carriers can be used at the same time on a single conveyor system. Each carrier having a lower surface, separate from the runners, for handling, storage and stacking of the carriers. The runners are removably attached to the carriers. The runners may be connected to the carriers at an angle with respect to the lower surface of the carriers. The runners may be the same length as the carriers, shorter than the carriers, or longer than the carriers. At least some of the runners may have two different riding surfaces spaced different distances apart, so that the same carrier can be used on different conveyor systems having different lateral wheel spacing. The runners can be selectively removably attached at two different locations on the carrier. The means for removably connecting the runners to the carriers may include snap-in devices.
