Abstract: A conveyor system has a plurality of cars displaceable along a track and each having a side provided with a plurality of parallel guides each in turn receiving a respective code marker slidable along the respective guide and arrestable therein at any of a plurality of predetermined index positions. The pattern defined by the markers in the index position determines the path of travel of the respective car on the track. A dispatcher is provided comprising a support adjacent the track and a plurality of rows of encoders on the support. Each row is alignable with a respective guide on one of the cars and each encoder is also alignable with the respective position on the respective guide. The encoders each comprise a remotely operable abutment pin projectable from the support into the respective guide such that displacement of a car past a support having one such abutment pin on each such row projecting from the support displaces the respective markers along the respective guides.
