Abstract: A sorter includes a slat and a shoe disposed along the slat. The shoe includes a base and a bumper. The base has an exterior surface. The bumper is coupled to the base. The shoe moves in a lateral direction along the slat to move an item across the slat. The bumper deflects when a threshold force is applied indicative of a jam to allow the item to slide over the base. A drive system is configured to move the slat in a longitudinal direction. The slat includes slat pins. A slat coupler couples the slat to the drive system. The slat coupler includes a carriage base, a coupler arm, and a retainer clip. The carriage base with pin notches is coupled to the drive system. The coupler arm with pin notches is pivotally coupled to the carriage base. The coupler arm is closed against the carriage base with the slat pins disposed within the pin notches. The retainer clip is clipped to the slat pins.
