Publication number: 20040169371Abstract: A novel speed lock fitting with a threaded drive pin that obviates any shock or vibration to the piping system, and can also be used in tight spaces where no one could practically swing a hammer. Assembly of the connecting fitting with drive pins as shown in the illustrations can be accomplished with a cordless electric driver or hand tool such as a wrench or socket wrench. Disassembly is then simply the reverse of assembly. The drive pin can be applied with greater net force to the pipe wall, thus making it a good choice for standard and heavy wall pipe.Type: ApplicationFiled: December 11, 2003Publication date: September 2, 2004Inventor: Howard H.

Patent number: 6748915Abstract: A cuff is clamped to a boss on an air resonator. The cuff has an inner leg with an o-ring seal sized to provide a seal against an inner periphery of the air resonator boss. A throttle body has a boss to be received within the inner leg of the cuff, and will also deform the o-ring seal. The inner leg preferably includes a second forward seal which also contacts the throttle body boss. Preferably, this second seal includes a spring for biasing the second seal against the throttle body boss. The cuff is initially placed on the air resonator which may then be mounted within the engine compartment. The throttle body may be then simply snapped into the cuff. In this way, no space around the connection is necessary, while a dust-free connection is still provided.Type: GrantFiled: September 26, 2002Date of Patent: June 15, 2004Assignee: Siemens VDO Automotive Inc.Inventors: Roderic Cole, Mark Letourneau, Frances Warren

Patent number: 6739630Abstract: A coupling member has an internally threaded end portion and an opposite socket end portion with a pair of axially-spaced internal circumferential grooves. The internally threaded end portion receives an externally threaded end portion on a pipe, while the opposite socket end portion receives an end portion of another pipe that has an external circumferential groove aligned with one of the pair of internal grooves. A spline is inserted into the aligned grooves through a transverse hole in the wall of the opposite end portion of the coupling member to hold the coupling member and the other pipe against relative axial movement. The spline is a wire rope to provide high shear strength.Type: GrantFiled: June 12, 2002Date of Patent: May 25, 2004Assignee: The Lamson & Sessions Co.Inventor: Charles H. Riedy
