Claims
- 1. Apparatus for attaching tags using fasteners, each fastener including a bar section and a button section joined by a filament section, the apparatus comprising: a body, a needle mounted by the body, the needle having an elongated slot communicating with the bore, a push rod engageable with the bar section of a fastener for driving the bar section through the bore while its filament section extends through the slot, means for advancing one fastener at a time into alignment with the bore including a toothed member, a movable member, means for driving the movable member to advance the toothed member and for driving the push rod, first and second guides secured to the body for guiding the movable member, the movable member including a flexible resilient first arm in slidable contact with the first guide, a second arm in slidable contact with the second guide, a flexible resilient third arm having a tooth cooperable with the toothed member, the first guide being cooperable with the first arm to urge the tooth into contact with the toothed member and to urge the second arm into contact with the second guide, both the first and third arms being yieldable as the pawl tooth moves relative to the toothed member.
- 2. Apparatus as defined in claim 1, wherein the pawl member and the arms are of a one-piece plastics construction.
- 3. Apparatus for attaching tags using fasteners, each fastener including a bar section and a button section joined by a filament section, the apparatus comprising: a body, a needle mounted by the body, the needle having an elongated bore and an elongated slot communicating with the bore, a push rod engageable with the bar section of the fastener for driving the bar section through the bore while its filament section extends through the slot, means for advancing one fastener at a time into alignment with the bore including a toothed member, a movable pawl member cooperable with the toothed member, means for driving the pawl member to advance the toothed member and for driving the push rod, the driving means including relatively movable slides and a lost-motion connection between the slides, a one-piece pawl member having a tooth cooperable with the toothed member and having an integrally formed flexible resilient arm for urging the tooth into cooperation with the toothed member, and means for movably coupling the one-piece pawl member to one of the slides so that as the slide to which the pawl member is coupled moves the pawl member will be moved relative to the toothed wheel.
- 4. Apparatus as defined in claim 3, including a guide post connected to the body, a guide groove in the post for guiding the push rod, and the flexible resilient arm bearing against the post.
