ABSTRACT:
A hand-operated stapler of the type comprising a base having an anvil die adjacent its front end, an open-top staple magazine pivotally coupled at its rear end to the base, and a lever also pivotally coupled to the base to depress the staple magazine onto the anvil die of the base whereby the foremost one of the staples within the magazine is dispensed therefrom to penetrate sheets of paper or the like and is further clinched by the anvil die to hold the sheets together. The stapler is characterized in that the staples within the staple magazine are urged forwardly by a feed element slidably mounted therein and a helical tension spring extending between the front end of the feed element and the front end of the lever, in such a manner that the spring is substantially folded over the rear end of the feed element.
