Patent number: 11828108Abstract: A cutting element includes a substrate that is axially symmetric about a central axis. The substrate has a radius perpendicular to the central axis and that extends from the central axis to an outer surface of the substrate. A super-hard material is coupled to the substrate, and the central axis passes through the super-hard material. The super-hard material has an external surface defining at least one ridge protruding from a remainder of the external surface. A central point on the central axis is offset from the external surface of the super-hard material by a distance equal to the radius of the substrate. A distance measured from the external surface of the super-hard material to the central point is greatest at a position between 25° and 45° from the central axis of the substrate.Type: GrantFiled: January 11, 2017Date of Patent: November 28, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Ronald B. Crockett, Dwain Norris, Aaron Madsen, Neil Cannon, John Daniel Belnap

Publication number: 20220178255Abstract: A bolster for a degradation pick includes a transverse cross section that is non-circular. Non-circular cross sections include square, triangular, hexagonal and other shapes. The bolster is made from a wear and/or erosion resistant material. The wear and/or erosion resistant material helps to protect the shank of the degradation pick. The bolster has a matching shape to the shape of the shank of the degradation pick.Type: ApplicationFiled: April 28, 2020Publication date: June 9, 2022Inventors: Ronald Crockett, Francis E. Leany, Dwain Norris, Braeden Brown

Patent number: 9909417Abstract: A degradation pick of the type used in such fields as road milling, mining, and trenching to engage and degrade tough materials such as asphalt, concrete, and rock may comprise a body attached at one end to a substantially cylindrical shaft. A hardened tip may also be attached to the body opposite the shaft. The hardened tip may comprise an axis offset from a central axis of the shaft. Such a degradation pick may be secured to an exterior of a rotatable drum or continuous chain so as to be repeatedly brought into contact with a surface of a material to be degraded. The body may comprise a protruding spine adjacent the hardened tip and opposite a direction of travel of the hardened tip when transported by a rotating drum or continuous chain.Type: GrantFiled: May 8, 2015Date of Patent: March 6, 2018Assignee: NOVATEK IP, LLCInventors: David R. Hall, Ronald B. Crockett, Dwain Norris, Gary Condon, Gary Peterson, Jeffrey Crockett

Patent number: 9803479Abstract: In such fields as road milling, mining and trenching it is often desirable to engage and degrade tough materials such as asphalt, concrete and rock. To do so, degradation picks comprising hardened tips may be secured to an exterior of a rotatable drum so as to be repeatedly brought into contact with a surface of a material to be degraded. To secure such degradation picks to the rotatable drum, a toroidal body comprising an interior surface rigidly attachable to the rotatable body and an exterior surface comprising a plurality of bore holes disposed there around may receive a plurality of degradation picks secured within the bore holes.Type: GrantFiled: July 22, 2015Date of Patent: October 31, 2017Assignee: NOVATEK IP, LLCInventors: David R. Hall, Ronald B. Crockett, Dwain Norris

Patent number: 9752434Abstract: In such fields as road milling, mining and trenching it is often desirable to engage and degrade tough materials such as asphalt, concrete and rock. To do so, degradation picks comprising hardened distal tips may be secured to an exterior of a movable support such as a rotatable drum or continuous chain so as to be repeatedly brought into contact with a material to be degraded. To secure such degradation picks to the movable support, a block comprising a body with a base surface rigidly attachable to a movable support is disclosed. A first receptacle with a first central axis may be disposed on an external surface of the body and formed to receive a first removable degradation pick. A second receptacle with a second central axis may also be disposed on the external surface and formed to receive a second removable degradation pick where the first and second central axes are nonparallel.Type: GrantFiled: July 24, 2015Date of Patent: September 5, 2017Assignee: NOVATEK IP, LLCInventors: David R.
