Patent number: 7909217Abstract: A pneumatically operated stapler that has a single selectively operable adjuster operatively associated with a staple leg diverter. The single selectively operable adjuster is constructed and arranged to be adjusted within a range of leg deflecting positions to affect the lateral movement of the staple leg diverter. The different leg deflective positions effects an amount to which the diverter will deflect the legs of the driven staple during a drive stroke. A single operation of the single selectively operable adjuster both moves the adjuster and retains the adjuster in an adjusted position within the range of leg deflecting positions.Type: GrantFiled: August 11, 2008Date of Patent: March 22, 2011Assignee: Stanley Fastening Systems, L.P.Inventors: Juan Ignacio Aguirre, Prudencio S.
