ABSTRACT:
The present invention is an ejector drive hub. The ejector drive hub comprises an axial through hole in a cylinder with a slot in the circumferential side wall of the cylinder. The slot truncates less than 180° of the cylinder. The ejector drive hub has an engagement face for a cam or pawl to drive it rotationally. A radial through hole in the slot forms a communicating opening between the slot and the axial through hole. The ejector drive hub further comprises a mount adapted to maintain a drive pawl in operative position relative to the radial through hole. The ejector drive hub further has at least one notch for engagement of a latch to maintain the ejector drive hub in a stationary position during knotting. The ejector drive hub has a boss to actuate an ejector. The boss and the disc portion of the ejector drive hub are integrally fabricated from a single piece of material as by machining.
