Publication number: 20150321271Abstract: Inserts for table saws are disclosed. The table inserts are equipped with a toolless locking mechanism that mechanically holds the insert in place and which allows for the installation and removal of the insert without the use of tools. The locking mechanism is easy to lock and unlock and yet robust enough to hold a zero-clearance insert in place.Type: ApplicationFiled: May 26, 2015Publication date: November 12, 2015Applicant: SD3, LLCInventors: John P.

Patent number: 8161653Abstract: A folding tool and an associated locking mechanism are provided in order to securely and reliably retain an implement, such as a knife blade, in an open position. The folding tool may include a handle, an implement pivotally connected to the handle and a lock. The lock, in turn, may include an engagement member for movement with the blade and a pivotable member, such as a cam member, configured to pivot relative to the handle between first and second positions. As a result of controlled interaction between the engagement member and the pivotable member, such as a result of camming action provided by the cam member, the rotatable implement can be secured in the open position. If desired, the rotatable implement may be released and folded into the closed position.Type: GrantFiled: November 12, 2007Date of Patent: April 24, 2012Assignee: Leatherman Tool Group, Inc.Inventor: John P. Nenadic

Patent number: 7712399Abstract: A tool and an associated bit driver are provided. The tool includes a handle and a bit driver carried by the handle. The bit driver can include a body defining a cavity for receiving a bit and a pivotable lock configured to move between a locked position in which the lock engages the bit and an unlocked position in which the lock is spaced and thereby disengaged from the bit. The pivotable lock can include a pivot pin, an engagement member for engaging the bit and an actuation member with the engagement and actuation members extending along the body in opposite directions from the pivot pin.Type: GrantFiled: October 5, 2007Date of Patent: May 11, 2010Assignee: Leatherman Tool Group, Inc.Inventor: John P. Nenadic

Patent number: 7676931Abstract: A folding hand tool with an open-assist mechanism that is not mechanically linked to a folding knife blade is disclosed. The open-assist mechanism is allowed to rotate around the same pivot used by the blade, and includes a lug that interacts with the kick of the blade when rotated. Because the open-assist mechanism is not mechanically linked to the blade, it has a range of free motion that promotes safety, and allows the mechanism to rotate into the blade cavity when the blade is extended. The folding knife also may have a carabiner that shares the blade cavity with the blade, with the blade nesting into the carabiner to save space, thereby giving the folding knife a smaller profile.Type: GrantFiled: June 14, 2005Date of Patent: March 16, 2010Assignee: Leatherman Tool Group, Inc.Inventors: Nathan E. Knight, Glenn A. Klecker, John P. Nenadic

Patent number: 7607231Abstract: A multipurpose tool includes bypass shears with handles that fold around the shears into a compact configuration in which the blades of the shears are hidden. A sharp-edged cutter is removable from the shears for resharpening or replacement, in one version of the tool. A blade safety lock holds the blades closed and is automatically engaged as the handles are folded. The handles are comfortably shaped and may include overmolded elastomeric cushioning portions.Type: GrantFiled: August 8, 2005Date of Patent: October 27, 2009Assignee: Leatherman Tool Group, Inc.Inventors: Glenn A. Klecker, John P. Nenadic
