The present invention provides a device for advancing fasteners in a magazine to a fastening tool. A plate assembly includes a base plate rigidly connected to a feed track and a pivot plate pivotally connected in a parallel orientation to the base plate. A motor is mounted to the pivot plate in such a manner that the motor shaft projects through aperatures near the center of each plate. A clutch assembly is mounted to the motor shaft and engages fasteners on the feed track. As the motor shaft rotates, the clutch assembly provides a friction force for advancing fasteners along the rack as each fastener is ejected. Between fastener ejections, the clutch assembly rotates and slips about the motor shaft. |
