ABSTRACT:
An improved system for dispensing a fastener through a slotted hollow needle from a continuously connected fastener stock, such apparatus incorporating an actuator slide with a central channel, such actuator slide being secured to the ejector rod and fastener stock feed mechanism to actuate these functions. The apparatus further includes a shuttle assembly which reciprocates transversely to the needle axis to cause the severing of a fastener from the fastener stock, and transport of the severed fastener to the needle axis. The cam bar is linked to the shuttle mechanism and pivotally mounted so that the pivotting of the cam bar causes the transverse shuttle motion. The cam bar passes through the actuator slide channel, whereby sliding of the actuator slide causes pivotting of the cam bar according to the profile of the cam. The apparatus, which is triggered-operated, further includes an antiback mechanism in the form of a catch lever which engages the trigger when it has been partially depressed and prevents its release, until the trigger has been fully depressed.
