ABSTRACT:
A device for actuating the unloading mat in switching machines of a type comprising elements capable of engaging a supporting roller for the mat, so as to control its rotation and effect the unloading of the transported object during the forward motion of the trolley holding the mat. The elements include a rack capable of engaging a sprocket solidly affixed to the shaft of one of the mat rollers, and the rack is mounted on a support subjected to the action of eccentric devices designed to govern the shifts from a position of rest to one of engaging with the sprocket. The rack is mounted on the support with the capability of performing small shifts against elastic devices, along a direction parallel to the direction of the trolley's forward motion.
