ABSTRACT:
A power roller conveyor has a plurality of rollers forming an article propelling and transporting surface. The rollers are powered from beneath by a continuously driven propelling member which has a width substantially less than the length of the rollers and is located midway between the ends of the rollers. The longitudinal axis of each of the rollers is slightly arched whereby each roller, in one rotational position, has driving engagement with the propelling member and, in a diametrically different position, disengages the roller, permitting the conveyor to serve either as a transport conveyor or as an accumulator having low line pressure and capable of automatically shifting from one mode to the other without the necessity for sensors or any other operating mechanisms.
