Abstract
A forward acting stapler includes a unique linkage for driving a firing lever. The linkage includes two links which are each connected to the trigger lever by a roller. The roller is movable within a spot in the trigger lever. As the handle is driven, the two links cause the triggering level to pivot. As the trigger lever pivots it lifts a plunger against a spring force. At some point, the trigger portion releases the plunger allowing the plunger to be returned by the spring force by a staple.
