Apparatus for dispensing a fastener through a slotted hollow needle, form stock formed by a plurality of fasteners, each having a filament with an angularly disposed bar at one end, comprising
- means, including a trigger, for advancing the fastener to the rear of the needle and forcing the end bar through the bore of the needle with its associated filament projecting through the slot of the needle;
- said trigger being mounted so that the compression force required to operate the trigger decreases as the trigger is depressed, by being directly secured to a movable pivot of a support rod for a coiled compression spring;
- and
- said support rod being secured to a fixed pivot within said apparatus and being mounted in an opening of said movable pivot to be movable through said opening in accordance with the extent to which said trigger is depressed.
