Patent number: 8104550Abstract: Earth-boring tools include wear-resistant materials disposed in at least one recess formed in an exterior surface of a body thereof. Exposed surfaces of the wear-resistant material are substantially level with exterior surfaces of the body adjacent the wear-resistant material. In some embodiments, recesses may be formed in formation-engaging surfaces of blades of earth-boring rotary tools, adjacent one or more inserts secured to bodies of earth-boring tools, or adjacent one or more cutting elements secured to bodies of earth-boring tools. Methods of forming earth-boring tools include filling one or more recesses formed in an exterior surface of a body with wear-resistant material and causing exposed surfaces of the wear-resistant material to be substantially level with the exterior surface of the body.Type: GrantFiled: September 28, 2007Date of Patent: January 31, 2012Assignee: Baker Hughes IncorporatedInventors: James L. Overstreet, Michael L. Doster, Mark E. Morris, Kenneth E. Gilmore, Robert M. Welch, Danielle V. Roberts

Publication number: 20110266060Abstract: Expandable reamer tools include an outer body, a fluid passageway extending through the outer body, and at least one blade configured to slide relative to the outer body between a refracted position and an expanded position in a direction oriented at an acute angle of less than ninety degrees (90°) to a longitudinal axis of the outer body. In some embodiments, the tools may include a moveable inner sleeve member configured to selectively allow hydraulic fluid pressure within the fluid passageway to act directly on the at least one blade. Methods for enlarging a borehole using such expandable reamer tools and methods for removing such expandable reamer tools from a borehole are also disclosed.Type: ApplicationFiled: July 13, 2011Publication date: November 3, 2011Applicant: BAKER HUGHES INCORPORATEDInventors: Steven R.

Patent number: 7350600Abstract: An earth-boring bit has a bit body that includes head sections, each having depending bit legs with a circumferentially extending outer surface, a leading side, and a trailing side. A bearing shaft depends inwardly from each of the bit legs for mounting a cutter. The bit includes a beveled surface formed at a junction of the leading side and the outer surface of each bit leg. The beveled surface is angled relative to a radial plane emenating from the axis of the bit. The angle of the beveled surface is at least 20 degrees, and extends to an inner surface of the bit leg. The bit can also have a layer of hardfacing on the leading, trailing and shirttail surfaces of the bit leg. A diversion finger of hardfacing extends circumferentially to direct cuttings.Type: GrantFiled: August 28, 2006Date of Patent: April 1, 2008Assignee: Baker Hughes IncorporatedInventors: Christopher C. Beuershausen, Raul E. Lema, Ronald Hales, Don Q. Nguyen, Gregory L. Ricks, Chih C. Lin, Terry J. Koltermann, Mark E. Morris, Chris M. McCarty, Ronald L. Jones, James L.

Patent number: 7066286Abstract: A gage scraper cleans mud from the gage surface of a rotary cone of a drill bit. The bit has a body having at least one leg depending therefrom, a bearing pin secured to each leg, and a rotary cutting cone mounted to the bearing pin. The cone has a conical gage surface. The gage scraper mounts on the inside of each leg and protrudes from the leg toward the cone into close proximity with the gage surface.Type: GrantFiled: March 25, 2004Date of Patent: June 27, 2006Assignee: Baker Hughes IncorporatedInventors: Don Q.

Patent number: 6651756Abstract: Hardfacing is deposited on a PDC-equipped steel body rotary drag bit and forms substantially protruding structural elements, such as wear knots or chip breakers. Hardfacing may also be applied to features such as gage pads, wherein at least two different hardfacing compositions are utilized and specifically located in order to exploit the material characteristics of each type of hardfacing composition employed. The use of multiple hardfacing compositions may further be employed as a wear-resistant coating on various elements of the drill bit. The surfaces to which hardfacing is applied may include machined slots, cavities or grooves providing increased surface area for application of the hardfacing. Additionally, such surface features may serve to effect a desired residual stress state in the resultant hardfacing layer or other structure.Type: GrantFiled: November 17, 2000Date of Patent: November 25, 2003Assignee: Baker Hughes IncorporatedInventors: Robert J. Costo, Jr., James L. Overstreet, Anton F. Zahradnik, James L. Duggan, Russel S. Smith, Mark E. Morris

Patent number: 4817322Abstract: A barrel protector which is positioned on the end of a weapon for maintaining the barrel free of water and dust. The barrel protector can fit over the end of a muzzle loader, shot gun, rifle, hand gun, or a military weapon. The barrel protector is plastic, or like material, which includes substantially continuous side rims for surrounding the end of a barrel, a covering member over the rim, a central portion of the covering member being thin. The thin central portion breaks away when the weapon is fired.Type: GrantFiled: September 9, 1987Date of Patent: April 4, 1989Assignee: Quality Mold, Inc.Inventors: Raymond Dietz, Mark E. Morris
