Publication number: 20220219350Abstract: Embodiments herein provide apparatuses, systems, and methods associated with a saw chain link having one or more oversized rivet holes. A rivet may be disposed in the oversized rivet hole and provide a clearance between the rivet and the edge of the oversized rivet hole that is about 0.010 inches or more. The clearance may permit the saw chain to move between two or more stable positions. The saw chain link may be a drive link, such as a cutter drive link or a bumper drive link. In some embodiments, the saw chain link may be a bi-directional saw chain link. Other embodiments may be described and claimed.Type: ApplicationFiled: February 23, 2022Publication date: July 14, 2022Inventors: Michael D. HARFST, Christopher D. SEIGNEUR

Patent number: 11247363Abstract: Embodiments herein describe presets for saw chains comprised of one or more rivets that are coupled to a tiestrap. Each rivet may further comprise a central flange and a hub protruding from opposed sides from the flange. In some embodiments, the hub may be non-concentric from the flange, and the flange may be non-circular, such as ovoid or cam-shaped. In some embodiments, various portions of the flange, rivet, and tiestrap may be selectively hardened to various degrees of hardness, depending upon their location and usage. In some embodiments, the rivets may be prevented from rotating with respect to the tiestrap using a brazing process, and may be configured to facilitate such processes. Other embodiments may employ a non-circular hub. Still other embodiments may use a low-temperature process for soldering that does not affect the hardness of the tiestrap or rivet.Type: GrantFiled: January 16, 2019Date of Patent: February 15, 2022Assignee: Oregon Tool, Inc.Inventors: Christopher D. Seigneur, Michael D. Harfst, Evan Pickett, James Matthew Cunnington

Patent number: 10195759Abstract: Embodiments herein describe a tie strap with a hardened integrated rivet for a saw chain. The tie strap has a body with an integrated rivet extending therefrom and having a shoulder extending from the body and configured to engage a rivet hole of a connector link and a hub extending from the shoulder and configured to engage a rivet hole of an opposing tie strap. The shoulder has a high wear region and a low wear region disposed opposite from the high wear region, wherein the low wear region has a first hardness that is less than a second hardness of the high wear region. Generally, the high wear region extends circumferentially around the shoulder and is between about 90 degrees counter clockwise to about 90 degrees clockwise measured from a center point on the shoulder facing inward toward a center part of the body.Type: GrantFiled: January 4, 2016Date of Patent: February 5, 2019Assignee: Blount, Inc.Inventors: Christopher D.

Patent number: 9038519Abstract: Embodiments herein provide a modified pitch sprocket to provide an orientation of a saw chain link, such as a cutter link or drive link, with respect to the direction of travel of the link, as it traverses the sprocket that is different than the orientation of the link as it traverses a straight portion of the guide bar. In some embodiments, the modified pitch sprocket may orient the cutter link to provide radial extension for a depth gauge of the cutter link relative to a cutting element of the cutter link. This may facilitate shaping of the depth gauge and/or cutting element, such as by a sharpening element, as the cutter link traverses the sprocket.Type: GrantFiled: March 14, 2013Date of Patent: May 26, 2015Assignee: Blount, Inc.Inventors: Mike Goettel, Michael D.

Publication number: 20130036614Abstract: Embodiments herein provide an involute slicer having a body portion and a blade coupled to the body. The involute slicer may further include an anvil to provide structural support to a workpiece. The blade may rotate about an axis. As the blade rotates, the blade may pass next to the anvil, thereby cutting the workpiece. The blade may include a cutting edge with a radius that increases from a proximal end to a distal end of the cutting edge. For example, the cutting edge may have an involute shape. The involute shape of the cutting edge provides a radially expanding cutting edge as the blade is rotated. In some embodiments, the blade may include a plurality of cutting edges, such as two cutting edges.Type: ApplicationFiled: August 9, 2012Publication date: February 14, 2013Applicant: Blount, Inc.Inventor: Christopher D.
