ABSTRACT:
In devices, such as overhead conveyors which have a main track and one or more spur tracks where carriers hold objects to be treated at the spur track stations, the carriers are towed or pushed along the main track by a chain tow means running in a guide which parallels the main track and are switched to the spur tracks for treatment. To save on costs, the spur tracks usually have an inclined portion so that the carriers move thereon to a treating station by gravity once they have been disconnected and switched from the main track. Here pusher means are provided on the tow chain to push the carriers out of the area of the switching zone, to thereby avoid collision with oncoming carriers and to push the switched carriers far enough that the force of gravity takes effect to cause the carriers to continue their movement.
