Patent number: 8495807Abstract: A prewinder apparatus attachable to a drive tool to install a helical coil insert includes a body connected to the drive tool. An adapter rotates and is releasably connected to the body at operator selected positions. A prewinder portion displaces in/out of the body. The prewinder portion translates into the body until a fastener engaged with the prewinder portion contacts a stop member defining a predetermined helical coil insert insertion depth. A mandrel axially extends from the prewinder portion when the prewinder portion moves into the body to rotatably insert the helical coil insert. A clutch engages/disengages the mandrel from a drive member. A second clutch or a stall device stalls the drive tool after coil insertion.Type: GrantFiled: June 25, 2009Date of Patent: July 30, 2013Assignee: Newfrey LLCInventors: Jan Szewc, William Giannakakos, William J.

Patent number: 7634844Abstract: A prewinder apparatus attached to a drive tool to install helical coil inserts includes an adapter attached to the drive tool. A rotatable tubular sleeve in the adapter is engaged with the tool drive and has opposed engagement walls of a longitudinal slot extending through a hollow portion. A mandrel has a threaded first end and a pin transversely extending from a second end positioned within the longitudinal slot. A stop slides within the adapter member and rotatably receives the sleeve. The stop has a plurality of external threads. A stop regulator rotatably disposed in the adapter member has internal threads engaged with the stop external threads.

Patent number: 6860173Abstract: A tool for installing a helical coil insert in a tapped hole formed in a workpiece includes a tubular body having a bore extending along its axis, a mandrel coaxially disposed in the bore of the tubular body, a motor for rotating the mandrel, and an air cylinder for applying an axial force to the mandrel. The tubular body includes a recess at one end for carrying a helical coil insert in alignment with the bore. An opening in the tubular body allows a user access to the recess. The tubular body is moveable to position the helical coil into selective engagement with the mandrel, whereby rotation of the mandrel installs the helical coil insert a selected depth in the tapped hole of the workpiece. In addition, the mandrel slides axially within the bore of the tubular body to remove the tang from the helical coil insert upon installation of the helical coil insert in the tapped hole.Type: GrantFiled: December 13, 2002Date of Patent: March 1, 2005Assignee: Newfrey LLCInventors: David W. Newton, William Giannakakos, William J. Lutkus, Michael Bardelli

Patent number: 6726422Abstract: Described herein are fastener inserts formed from a titanium alloy which reduce corrosion in a fastener assembly. In addition to reduced corrosion, particularly galvanic corrosion, the fastener insert is lightweight and provides improved strength to weight ratios as compared to stainless steel fastener inserts.Type: GrantFiled: November 2, 2001Date of Patent: April 27, 2004Assignee: Newfrey LLCInventor: William Giannakakos

Patent number: 6726421Abstract: A helical thread insert having a removable tang attached to the front end of the insert, a retention device, and a removal notch located along the rear portion of the insert. The removable tang is oriented radially inward and includes a “V” shaped notch oriented along a bottom of a thread to detach the tang at a specified point. The retention device is located at a rear end of the thread insert and prevents counterclockwise, or removal rotation of the insert by engaging female threads of the bore in which the helical thread insert is disposed. The removal notch is formed along an inner surface of the insert proximal to the retention device to allow a tool to actuate the retention device inward, generally away from the female threads of a parent material, to allow relatively free counterclockwise rotation and removal of the thread insert.Type: GrantFiled: September 10, 2001Date of Patent: April 27, 2004Assignee: Newfrey LLCInventors: William Giannakakos, John F. Carvalho

Patent number: 6704984Abstract: A prewinder apparatus for selective attachment to an installation tool is provided. The prewinder apparatus includes a support structure selectively attachable to the installation tool, a prewinder attached to the support structure, the prewinder having first and second threaded apertures, and a mandrel having a threaded end and a coupling end. The threaded end is in threaded engagement with the second threaded aperture. The coupling end is in selective operable engagement with the drive tool, whereby the drive tool rotatably drives the mandrel relative to the prewinder for rotatably driving the helical coil insert through the second threaded aperture to prewind the helical coil insert.Type: GrantFiled: July 31, 2001Date of Patent: March 16, 2004Assignee: Newfrey LCCInventors: Jan Szewc, William J. Lutkus, William Giannakakos

Publication number: 20030215296Abstract: An insert useful for replacing damaged threads in a hole is provided. The damaged threads originally extend along an axial length of the hole. The insert has an inner surface having inner threads corresponding to the damaged threads being replaced. The insert also has an outer surface having outer threads extending an axial length that is greater than the originally extending axial length of the damaged threads. The insert may be used to replace damaged threads in a spark plug hole. A kit including the insert, a tap having a thread milling section, and a retention mechanism implement is also provided. Preferably, the retention mechanism implement is an expansion tool for imbedding knurled threads into surrounding material. The tap has torque engagement mechanism with an outer radial dimension which is substantially equal to or smaller than the maximum outer radial dimension of the tap. An associated method is also provided.Type: ApplicationFiled: May 20, 2002Publication date: November 20, 2003Inventors: John D. Botelle, Ron Phillips, William Giannakakos

Patent number: 6644149Abstract: An apparatus for removing helical thread inserts having a removal notch formed along a female thread surface. The apparatus can selectively extract helical thread inserts by selectively engaging the removal notch and actuating the end of the insert radially inward to prevent the end of the insert from engaging threads of the bore which it is disposed in. The apparatus includes a handle, a head attached to the handle, and a manually operable key. The head includes a bore formed therethrough having a central axis offset from central axis of the head, whereby the key is rotatably supported in the bore and includes an engaging lip for selectively engaging the removal notch of the insert and allowing for easier removal of the insert.Type: GrantFiled: September 17, 2001Date of Patent: November 11, 2003Assignee: Newfrey LLCInventors: William Giannakakos, William Lutkus, J.
