ABSTRACT:
A tool for a programmed assembly machine reliably dispenses nuts into sockets which in turn drive the nuts onto screws. The nuts rest on thin gate blades and loosely engage guide pins projecting up from the drive sockets. To dispense, the blades are pivoted by an actuator pin on the gripper to slide from under the nuts which fall by gravity onto the drive sockets, guided by the projecting pins. Other small apertured fastener parts such as washers can be dispensed by the tool.
