Patent number: 11926070Abstract: Embodiments include a bar for a chain saw that is equipped with one or more oil channels that run along the length of the bar. Each oil channel receives oil at a first end, which exits the oil channel at an oil exit aperture at a second end of the channel. The oil exit aperture of one of the channels is positioned along the side of a bar groove, through which runs the saw chain, proximate to the cutting area of the bar to lubricate the saw chain just prior to the cutting area. A second channel may have an oil exit aperture proximate to the nose of the bar, to lubricate a sprocket wheel in the nose of the bar.Type: GrantFiled: November 11, 2021Date of Patent: March 12, 2024Assignee: Oregon Tool, Inc.Inventors: Eric M. Burmester, Michael D. Harfst, Sam Hutsell, Genesis McDermott, Patrick Sellars, James Matthew Cunnington, Jonah Smith Sedaghaty

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

Publication number: 20180304489Abstract: Embodiments provide for a lubricant delivery system that includes a saw chain guide bar, such as a harvester bar, and an integrated lubrication channel insert that is insertable into the saw chain guide bar. Oil, grease, or other lubricant can be passed to the chain to the groove bottom to lubricate the chain during use though the lubrication channel insert, as disclosed herein. The lubricant enters the groove via the lubrication channel insert opening into the guide groove in the region of the groove bottom. The lubrication channel insert is coupled to the guide bar and is fed from a transverse lubrication channel lying below the groove bottom. Also provided is a lubrication channel insert.Type: ApplicationFiled: April 19, 2018Publication date: October 25, 2018Inventors: Don Cornette, Eric M. Burmester, James Matthew Cunnington

Patent number: 9545794Abstract: A method of performing maintenance on a printhead of an imaging device includes the detection of at least one contaminated ink jet in a printhead. A first pressure is applied to ink in the printhead in response to the detection of the at least one contaminated ink jet. The first pressure is configured to prevent ink from entering a plurality of apertures in an aperture plate of the printhead and to prevent ink from drooling from the plurality of apertures unless the apertures are wiped by a wiper blade. A first portion of apertures in the plurality of apertures in the aperture plate is wiped with a wiper blade while leaving a second portion of the apertures untouched by the wiper blade while the first pressure is applied to the ink in the printhead. The wiping of the first portion of apertures enables ink to drool from the first portion of apertures. The first portion of apertures includes the at least one detected contaminated ink jet.Type: GrantFiled: April 28, 2009Date of Patent: January 17, 2017Assignee: Xerox CorporationInventors: James Matthew Cunnington, Trevor James Snyder, Edward F. Burress, Heidi Noce

Patent number: 8783819Abstract: A method increases the ability of a controller in a printer to detect weak or missing inkjets in the printer. The method includes generating a test pattern having at least twice as much ink as a typical test pattern used to detect weak or missing inkjets. The increased ink appropriately stresses inkjets to facilitate detection of weak or missing inkjets and the test pattern is transferred to media and removed from the printer to preserve the capacity of a drum maintenance unit to store residual ink removed from an imaging drum or belt.Type: GrantFiled: January 18, 2012Date of Patent: July 22, 2014Assignee: Xerox CorporationInventors: Trevor James Snyder, James Matthew Cunnington

Patent number: 8136934Abstract: A printhead for use in an imaging device includes a reservoir configured to receive ink from an ink source. An aperture plate includes a plurality of ink jet apertures at a first location in the aperture plate and a plurality of recycling apertures at a second location in the aperture plate. The printhead includes a plurality of ink jets, each ink jet being configured to receive ink from the reservoir and to reject ink through one of the ink jet apertures in the aperture plate, and a plurality of channels, each channel being configured to fluidly couple one of the recycling apertures in the aperture plate to the reservoir. A pressure source is coupled to the reservoir that is configured to generate a pressure in the reservoir.Type: GrantFiled: February 18, 2009Date of Patent: March 20, 2012Assignee: Xerox CorporationInventors: Trevor James Snyder, James Matthew Cunnington

Patent number: 8091980Abstract: A method of performing maintenance on a printhead of an imaging device includes the application of a purge pressure to ink in an on-board reservoir of the printhead to cause ink to be burped through a plurality of apertures in an aperture plate of the printhead. A wiper blade is then dabbed on the aperture plate at least once after the application of the purge pressure. After the dabbing, the wiper blade is drawn across the aperture plate. The wiper blade is then dabbed against the dabbing position at least once after wiping the aperture plate.Type: GrantFiled: April 28, 2009Date of Patent: January 10, 2012Assignee: Xerox CorporationInventors: Trevor James Snyder, James Matthew Cunnington, Rodney Bryant Hill, Kathleen M.

Patent number: 7901035Abstract: A drip bib for use with a printhead of an imaging device includes a plate having an upper surface having an upper edge, an intermediate surface angled with respect to the upper surface, and a lower edge. The intermediate surface includes a plurality of fastener openings. The lower edge includes a drip point projecting from the lower edge with remaining portions of the lower edge being upturned and angled downwardly from at least one end of the lower edge toward the drip point. A plurality of protrusions protrudes from a back side of the upper surface. The protrusions in the plurality of protrusions are spaced from each other and proximate the upper edge.Type: GrantFiled: February 27, 2009Date of Patent: March 8, 2011Assignee: Xerox CorporationInventors: David Roland Koehler, Edward Charles Grenier, Gerard Rousseau, Garry Adam Jones, Michael Edward Norkitis, James Matthew Cunnington, Hattie Raeann Hiatt
