ABSTRACT:
There is disclosed a plurality of embodiments of tag attaching apparatus of the type having a hollow needle with a slot along one side, an ejector or push rod aligned with the needle, and feeding means for successively advancing an assembly of fasteners into position to be pushed through the needle by means of the push rod. In accordance with one embodiment, means for moving the push rod and the pawl includes cooperating gears and one of the gears includes a groove or slot. A link movably connected to the pawl carries a projection received in the groove. The groove terminates at spaced apart abutment faces. The gears are driven by an actuator. When the actuator is operated, the gear with the groove moves until one abutment face contacts the projection to move the pawl from a first position to a second position and when the actuator is released the gear with the groove moves relative to the projection until the other abutment face contacts the projection and moves the pawl to in turn drive the toothed wheel.
