Patent number: 7914244Abstract: A threaded fastener includes a shank having a tip and a head configured for engagement by an associated driving tool. The fastener is configured for use with an associated threaded opening. The head is disposed on the shank opposite the tip. The shank has a helical thread formed thereon. The thread extends from about the tip to about the head and defines a plurality of zones. Each zone has a plurality of individual threads extending 360 degrees about the shank. A leading thread in each zone is formed with a wave-form profile having an amplitude that is greater than the amplitude of each prior leading thread. In one embodiment, threads other than the leading thread in each zone do not have an amplitude as great as their respective leading threads. A fastening assembly is also disclosed.Type: GrantFiled: January 23, 2008Date of Patent: March 29, 2011Assignee: Illinois Tool Works Inc.Inventors: John S. Bubulka, Joel M.

Patent number: 7628414Abstract: A damper system is connected between pivotal components of a vehicle suspension system to inhibit movement of the components during a condition of potential vehicle roll. The system can be actively or passively controlled. The damper system can have a single damper or multiple dampers and may be connected to work in conjunction with vehicle stabilizers including torsion bars, single compensator stabilizing systems and dual compensator stabilizing systems. In the compensator stabilizing systems, the damper can be separate from the compensators or integral with the compensators. The dampers also can be formed as integral structures with shock absorbers. The dampers can be of various types, including but not limited to linear dampers and rotary dampers.Type: GrantFiled: July 25, 2005Date of Patent: December 8, 2009Assignee: Illinois Tool Works Inc.Inventors: Kenneth S. Dobson, Robert K. Dutzi, Jason K. Trotter

Publication number: 20090074535Abstract: A fastener assembly configured to secure a component to an interior wall of a housing includes a wall mount configured to securely mount to the interior wall of the housing. The wall mount includes a first plate secured to a second plate through a neck. The first plate has a larger axial cross-sectional area than the second plate, which, in turn, has a larger axial cross-sectional area than the neck. The second plate is configured to pass through a portion of a securing passage formed through the housing. The first plate is larger than the portion of the securing passage, so that the first plate is unable to pass through the securing passage. The wall mount is configured to be rotated into a locked position with respect to the securing passage, wherein the wall mount is prevented from shifting in the locked position.Type: ApplicationFiled: August 27, 2008Publication date: March 19, 2009Inventors: CHRISTOPHER D.

Patent number: 7261488Abstract: A ball socket ring seal for use with a ball joint assembly eliminates the need for a boot or bellows to protect the ball joint against the environment. The ball socket ring seal of the invention is positioned between the ball and the socket at the point of contact between the ball and socket. The ball socket ring seal not only provides a seal against the environment, it further functions as a wiper for the ball during articulation of the ball stud. The ball socket ring seal of the present invention reduces the weight and complexity of the ball joint assembly through the elimination of several parts, including the known boots or bellows, retainer rings, bands and clips.Type: GrantFiled: April 23, 2004Date of Patent: August 28, 2007Assignee: Illinois Tool Works IncInventors: Kenneth S. Dobson, Robert K. Dutzi, Dennis M. Mark

Patent number: 6929271Abstract: The present technique provides a stabilizer system comprising a plurality of piston cylinder assemblies, which have multiple interconnected chambers to provide cross compensation between suspension members coupled to those piston cylinder assemblies. The piston cylinder assemblies may have two or more chambers separated by pistons, which move in response to a load imposed on the suspension member coupled to that piston cylinder assembly. As the piston moves in response to movement of the corresponding suspension member, a fluid pressure is transmitted to another suspension member to distribute the load between the two suspension members.Type: GrantFiled: November 9, 2001Date of Patent: August 16, 2005Assignee: Illinois Tool Works Inc.Inventors: Jason K. Trotter, Robert K. Dutzi, Thomas S. King

Patent number: 6875388Abstract: A molding-in-place technique for joint assemblies, such as a ball joint. The technique is particularly well suited for molding “in-place” a linkage structure about a joint structure. The technique uses a molding assembly having a plurality of centering and sealing structures for sealingly centering the linkage structure about the joint structure. A desired mold material is injected between the linkage structure and the joint structure “in-place” to provide a self-toleranced, self-retained, molded-in-place joint assembly.Type: GrantFiled: November 7, 2001Date of Patent: April 5, 2005Assignee: Illinois Tool Works Inc.Inventors: Jason K.
