  • Publication number: 20170173818
    Abstract: Blade guards for power tools such as table saws are disclosed. The blade guard may include a shroud that pivots up and down to allow a workpiece to move past the guard, a dust collection channel, and a pivot joint which maintains the dust collection channel in an operable condition as the shroud pivots up or down. The guard may also include a wood stop and anti-kickback pawls. The blade guard may be part of a dust collection system and may be connected to a vacuum system by a conduit such as a flexible hose.

  • Publication number: 20150321271
    Abstract: 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.

  • Patent number: 8161653
    Abstract: 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.

  • Patent number: 7712399
    Abstract: 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.

  • Patent number: 7676931
    Abstract: 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.

  • Patent number: 7607231
    Abstract: 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.
