Portable fastener setting press

A manually operable press for installing fasteners in flexible material comprising:

• a 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, said lower leg including an upwardly extending base portion which extends generally parallel to said back portion to define a vertically open throat;
• a ram member carried in said upper leg and guided for reciprocating movement along a path generally parallel to said back portion toward and away from said base portion of said lower leg;
• and,
• drive means for driving said ram member toward said base portion of said lower leg, said drive means including first and second drive levers mounted for pivotal movement in the upper leg of said frame about fixed axes which extend transversely of the path of movement of said ram, said first drive lever having a first end in direct driving engagement with said ram and a second end extending rearwardly of said path, said second end of said first drive lever drivingly connected to a first end of said second drive lever by a connecting link member having a first end pivotally connected to the second end of said first drive lever and a second end pivotally connected to the second end of said second drive lever, and a second end of said second lever constituting a manual drive handle and arrange to extend generally parallel to the back portion of said frame when said second lever has been moved to a position wherein said ram member is driven to generally the maximum extent of movement toward said lower leg and, further wherein said second drive lever is mounted so that the second end thereof can pivot from a position where it extends generally perpendicular to said back portion to a position where it extends generally parallel to said back portion.
