LINE SHAFT DRIVE FOR POWERED ROLLER CONVEYOR ABSTRACT OF THE DISCLOSURE A drive mechanism for a powered roller conveyor wherein a continuously driven line shaft extends transversely of the conveyor rollers substantially in the longitudinal direction of the conveyor. A plurality of friction driving rollers are spaced longitudinally along the line shaft and are disposed with their respective rotational axes extending approximately parallel with the conveyor roller axes, whereby these driving rollers are disposed in friction driving engagement with the conveyor rollers so that each conveyor roller is directly driven from one of the driving rollers. In a preferred embodi- ment, a plurality of shiftable sleeves, preferably of conical configuration, are slidably mounted on the line shaft and are rotatable therewith. These sleeves can be shifted into fric- tion driving engagement with an axial end face on the driving rollers to selectively drive same. This driving mechanism is usuable both throughout straight and curved conveyor sections, and permits simplified zoning of the conveyor in its longitu- dinal direction whereby substantially zero pressure accumula- tion of articles on the conveyor is possible.
