TAG ATTACHER Abstract of the Disclosure There is disclosed a hand-held apparatus for attaching tags to merchandise. Apparatus according to the invention uses a fastener assembly having a plurality of fasteners. Each fastener has a bar section and a button or head section joined by a filament section. Each bar section is connected to a common runner or rail by a respective neck or connector. The apparatus causes one fastener at a time to be severed from the connector at the intersection of its bar section and the respective connector. The bar section of the severed fastener is pushed by a push rod through an elongated bore of a needle while the filament section passes along a side opening in the needle which communicates with the needle bore. Fastener assembly advancing means includes a toothed member and a movable member. A guide is provided for the movable member and a flexible resilient arm connected to the movable member exerts a force on the guide. The arm enables the movable member to deflect as it moves relative to the guide. In the illustrated embodiment the movable member takes the form of a pawl cooperable with the toothed member. A detent member cooperates with another toothed wheel of the fastener assembly advancing means to prevent accidental movement of the other feed wheel. The detent member has a tooth, a socket portion and an arm extending into a hole in the body. A compression spring acts on the detent member between the socket portion and the tooth. The end of the arm of the detent member is depressible to release the tooth of the detent member from the other toothed member. In another embodiment, a movable member includes a pawl member and a flexible resilient arm which moves with the pawl member. The arm is in contact with a first guide and urges the pawl member into contact with a toothed member and a second guide. In still another embodiment, a plurality of flexible resilient arms are connected to the pawl member and are in contact with a first guide for urging the pawl member into contact with a toothed member and a second guide. In yet another embodiment, a pawl member includes a first flexible resilient arm having a tooth at its free end portion cooperable with the toothed member and a second flexible resilient arm connected to the pawl member and movable with the pawl member. In another embodiment, relatively movable slides are coupled by a lost-motion connection. A one-piece pawl coupled to one of the slides has a tooth cooperable with the toothed member and a flexible resilient arm cooperable with a guide for urging the tooth into cooperation with the toothed member.
