ABSTRACT:
A roller conveyor includes driven rollers, drive to which is transmitted through resilient drive belts looped about the rollers and about drive sleeves carried for rotation on and frictional engagement with a drive shaft, which extends longitudinally of the conveyor and adjacent the rollers. The drive sleeves consist of tubes carried on the shaft on nylon bush bearings and are restrained from axial movement along the drive shaft and the drive belts are in direct engagement with the surface thereof to assume a stable position thereon. When an article being transported is halted by external means the frictional drag between the bushes and the shaft is exceeded and the sleeve beneath the article and all associated rollers stall, thus preventing further articles being transported by those rollers.
