Publication number: 20150021016Abstract: A device is taught for measuring and wirelessly transmitting one or more parameters during wellbore operations. The device comprises a torque sub releasably connected to a top drive at a first end and having a second end such that the torque sub rotates with the rotating top drive, one or more sensors for measuring rotational, torque and torsion parameters, a wireless power source and a signal transmitter connected to the one or more sensors for wireless transmission of data collected by the one or more sensors to a computer. Systems and methods are also provided for connecting threaded tubulars for use in a wellbore.Type: ApplicationFiled: March 28, 2012Publication date: January 22, 2015Applicant: MCCOY CORPORATIONInventors: Bing Deng, Murray Gerwing, Gerhard Oberforcher, Trent Michael Schatz

Patent number: 8479614Abstract: A power tong jaw comprising a jaw body having upper and lower flange sections with flange apertures formed through the upper and lower flange sections. The power tong jaw will further have a jaw roller including a pin aperture and a roller pin positioned through the pin aperture in the jaw roller and through at least one of the upper or lower jaw flange apertures. The power tong jaw will further include a flexible retaining mechanism (i) positioned between outer surfaces of the upper and lower flange and (ii) engaging the roller pin.Type: GrantFiled: August 6, 2012Date of Patent: July 9, 2013Assignee: McCoy CorporationInventors: Murray Gerwing, Steven Hargreaves, Jeremy Vaughan, Kelvin Isaacson

Patent number: 8453541Abstract: A power tong body having a central opening comprises upper and lower cover plates and a rotary gear contained there between. The tong incorporates the centering guide, e.g. rollers, that extend between the rotary gear and respective tong covers. Such centering guides through the central openings in the tong body covers and provide contact surfaces carried that permit differential rotation of the rotary gear with respect to such covers. The rollers may roll on circular races formed by the inside edge face surfaces of the tong covers bordering the central opening. The support rollers may also extend beyond the upper and lower cover plates and engage with a guide surface or race formed on the respective cage plates of the tong, centrally locating such cage plates with respect to the rotary gear while allowing differential rotation of the cage plates with respect to the rotary gear.Type: GrantFiled: April 29, 2009Date of Patent: June 4, 2013Assignee: McCoy CorporationInventors: Dan Dagenais, Murray Gerwing, Steven Hargreaves

Patent number: 8267448Abstract: A backup tong that comprises an activating mechanism for advancing a jaw die mounted on a jaw carrier within the backup into engagement with a pipe positioned centrally therein. The jaw carrier is fitted within the tong body to permit a sliding action radially toward the center point of the opening in the backup tong. Such mechanism includes a cam surface located along a first extension of a cam arm which pivots around a fixed pivot pin carried by the body of the backup. The other extension of the cam arm is connected toward its outer end to an actuator, anchored at one end to the backup body and oriented at the other end to swing the cam arm about the pivot pin.Type: GrantFiled: April 30, 2010Date of Patent: September 18, 2012Assignee: McCoy CorporationInventors: Dan Dagenais, Murray Gerwing, Steven Hargreaves
