Claims
- 1. In a stapler of the type including a base having an anvil die adjacent one end thereof, an open-top staple magazine having a staple dispensing aperture provided at distal end in a bottom wall thereof, said magazine being pivoted at its proximal end to the other end of said base so as to be turnable up and down relative thereto, a lever having a staple ejector at its distal end and also pivotally connected at its proximal end to the other end of said base so as to be turnable up and down relative thereto, said lever being adapted to drive each foremost staple accommodated within said staple magazine out of said dispensing aperture by said staple ejector such that the dispensed staple is clinched by said anvil die to hold layers of penetrable material together, a feed element slidably mounted within said staple magazine behind the staples accommodated therein, and spring means urging said feed element toward said dispensing aperture to feed the staples toward the dispensing aperture:
- an improvement comprising a punching die on said base intermediate the ends thereof and having a planar surface and a bore formed therein;
- a perforating punch extending downwardly from the bottom of said staple magazine at a position to be received in said bore of said punching die when said staple magazine is depressed onto said base; and
- a pin pivotally coupling at least said staple magazine at its proximal end to said other end of said base so that said magazine can be pivoted independently of said lever, said pin having an axis located on a line of intersection between the plane of said surface of said punching die and the plane of said bottom surface of said staple magazine.
- 2. A stapler as claimed in claim 1, further comprising a thumbpiece at said distal end of said staple magazine, said thumbpiece being positioned for use in depressing only said staple magazine onto said base to punch without effecting a stapling operation a hole in a layer of penetrable material by said perforating punch.
- 3. A stapler as claimed in claim 1, wherein said base includes a pair of upstanding parallel side walls respectively provided with slots extending parallel to and on both sides of said surface of the punching die, said slots receiving and retaining therein sheet material to be punched.
