ABSTRACT:
A tag attaching gun in which an ejector rod is advanced by a trigger operated lever to sever an individual fastener from a fastener assemblage and dispense the severed fastener through a hollow slotted needle. This apparatus incorporates a unitary, single-tooth feed member for advancing the fastener assemblage to bring the forwardmost fastener in line with the needle. Such feed member comprises a reciprocably mounted body integral with a U-shaped resilient finger terminating in a feed tooth. The feed member together with its resilient feed finger moves linearly in order to engage and advance the fastener assemblage, while the finger flexes during a return motion in order to clear a succeeding fastener in the assemblage.
