Abstract
A hammer-type stapler in which the staple driving element and the staple drive track defining structure are constructed and arranged with respect to the frame structure to move through a drive stroke incident to an operator grasping a handle portion and manually impacting the staple drive track defining structure on a workpiece to arrest the movement of the drive track structure on the workpiece while the frame structure and the staple driving element continue to move toward the workpiece with respect to the arrested drive track structure. The staple driving element is constructed and arranged with respect to the frame structure and the drive track structure such that the continued movement of the staple driving element toward the workpiece with respect to the arrested drive track structure is further and faster than the continued movement of the frame structure toward the workpiece with respect to the arrested drive track structure enabling the staple driving element to effect a drive stroke through the drive track and to drive a staple therein into the workpiece while the frame structure is undergoing a relative movement with respect to the drive track structure which is less than substantially equal to the relative movement of the staple driving element with respect to the drive track structure during the drive stroke of the staple driving element.
