| 20120036725 | KICKBACK DETECTION METHOD AND APPARATUS - 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. | 02-16-2012 |
| 20110177301 | CUTTING BLADE HARD-FACING METHOD AND APPARATUS - 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. | 07-21-2011 |
| 20110100188 | DRIVE LINK WITH IMPROVED LUBRICATION FEATURE - 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. | 05-05-2011 |
| 20110061639 | AGGREGATE CUTTING SAW CHAIN - Embodiments of the disclosure provide an aggregate cutting saw chain having a pitch in the range of approximately 0.440 to approximately 0.450. Embodiments also include tie straps and/or other components having fluid distribution features. | 03-17-2011 |
| 20110030223 | BAR MOUNTED SHARPENER - 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. | 02-10-2011 |
| 20100058915 | SAW CHAIN DRIVE LINK WITH TAIL - 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. | 03-11-2010 |
| 20100043377 | CUTTING BLADE HARD-FACING METHOD AND APPARATUS - 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. | 02-25-2010 |
| 20100008740 | ROTARY CUTTER - Embodiments provide a helical cutting tool and a helical cutting bit that may be utilized to cut various materials. The helical cutting bit and cutting tool include a variety of features to increase the efficiency of the cutting tool during cutting operations. | 01-14-2010 |
| 20100005668 | UTILITY CHAIN CUTTER - Embodiments provide various saw chain links which may be combined to form a utility saw chain. In various other embodiments, cutting system fixtures are disclosed which may facilitate the cutting of pipes and other materials from an axis point. | 01-14-2010 |
| 20100005666 | CHAIN LINK SHARPENING METHOD AND APPARATUS - Embodiments provide various components of a chain saw, including saw chain elements, sprockets, and other fixtures, that may facilitate sharpening of cutter links during operation. In various embodiments, the components may increase stability during sharpening, provide nose mounted sharpening fixtures, and/or facilitate the resizing and/or reshaping of a sharpening element. | 01-14-2010 |
| 20090255393 | SHEAR RESISTANT RIVET AND SAW CHAIN - A saw chain rivet is provided including a flange, and a hub extending from a side of the flange. A shoulder defined by a junction between the hub and the flange has properties optimized to resist shear forces. The hub may be optimized for ease of rivet head formation. | 10-15-2009 |
