ABSTRACT:
A conveyor handling system is described in which two endless belts are serially arranged along a predetermined path. The rollers supporting the two belts at adjacent ends of the belts are mounted on a common rotary shaft. The rotary shaft is supported upon a reciprocatable carriage which also supports the downstream belt and when activated, the carriage is arranged to reciprocate the downstream belt bodily. The upper run of the upstream belt is extendable to follow the reciprocation of the downstream belt. The upstream belt is driven at a constant speed.The downstream belt, which is coupled to the rotary shaft through a one way clutch, is initially driven at the same speed as the upstream belt, but when the carriage is reciprocated (at a speed greater than the upstream belt), the clutch locks and the downstream belt adopts the speed of the carriage.
