  • KICKBACK DETECTION METHOD AND APPARATUS
    Publication number: 20120036725
    Abstract: In various embodiments, a cutting tool such as a chainsaw may include a cutting member that is movable by an engine, one or more sensors configured to detect one or more of acceleration in a direction parallel to one or more axes of the cutting tool and rotational velocity about one or more axes of the cutting tool, and a microprocessor configured to cause movement of the cutting member to stop in response to receiving one or more signals from the one or more sensors. In various embodiments, a method may include receiving, by a microprocessor of a chainsaw, a signal from a gyroscope configured to detect rotational velocity about one or more axes of the cutting tool, and actuating, by the microprocessor, a braking system of the chainsaw to stop movement of a cutting chain around a perimeter of a guide bar in response to the signal.

  • Saw chain drive link with tail
    Patent number: 8006598
    Abstract: A saw chain for a chain saw is disclosed. Embodiments include a drive link that may be used in a saw chain, wherein the drive link includes a tail and a concavity that complements a depth gauge of a trailing cutting link, reducing and/or minimizing the drive link's protrusion into a gullet space of the cutting link. Embodiments of the invention may help improve cutting performance and further help reduce kickback potential.

  • CUTTING BLADE HARD-FACING METHOD AND APPARATUS
    Publication number: 20110177301
    Abstract: A hard-faced cutting blade and hard-facing method is provided. A hard-facing material is applied to a cutting edge of a cutting blade such that a heat-affected transition zone may be created between the base metal and the hard-facing material. The heat-affected transition zone may create a sufficient bond to help resist delamination and flaking of the hard-facing material from the base metal.

  • DRIVE LINK WITH IMPROVED LUBRICATION FEATURE
    Publication number: 20110100188
    Abstract: Various embodiments of the present disclosure generally provide a drive link for a saw chain including a body portion adapted to couple to adjacent side links and a tang extending from the body and sized to engage a guide bar groove. The tang may include a through hole extending from a first tang side to a second tang side and including a through hole center. In various embodiments, a material directing feature may be disposed adjacent to the through hole on at least one of the first side and second side of the tang. The material directing feature may include a recession in the tang which encourages oil and/or wood chips to pass through the through hole.

  • BAR MOUNTED SHARPENER
    Publication number: 20110030223
    Abstract: Embodiments include a sharpening fixture adapted to mount to the nose of a chainsaw guide bar. When mounted, the operator may direct a force towards the guide bar thereby causing a linear directed actuator to move a sharpening element into engagement with cutters of a saw chain to sharpen a cutting edge of the cutters. In various embodiments, the actuator is biased such that when the force is no longer applied, the actuator pulls the sharpening element out of engagement with the cutters.
