ABSTRACT:
A manually operable press for installing fasteners in flexible material comprises a one piece relatively rigid frame of generally C-shape having a vertically extending back portion and a pair of laterally extending and vertically spaced upper and lower legs. A ram is carried in the upper leg and is guided for reciprocating movement along a path toward and away from the lower leg. The ram is driven toward the lower leg by a drive assembly comprising first and second drive levers mounted for pivotal movement in the upper end of the frame. The first drive lever has a first end in driving engagement with the ram and a second end drivingly connected by a toggle link to a first end of the second drive lever. A second end of the second lever constitutes a manual drive handle and is arranged to extend generally parallel to the back portion of the frame when the second lever has been moved to a position wherein the ram member is driven to generally the maximum extent of its movement toward the lower leg.
