Publication number: 20070151074Abstract: The present application is directed to a power tool handle comprising a gripping member and one or more support assemblies. The one or more support assemblies comprise a first support portion coupled to the gripping member and a second support portion having an end part configured to cooperate with a desired height adjustment mechanism. The first and second support portions are coupled together using one or more vibration isolating members. The one or more vibration isolating members are not part of the selected height adjustment mechanism, although the selected height adjustment mechanism may comprise additional vibration isolating members, if desired.Type: ApplicationFiled: January 3, 2006Publication date: July 5, 2007Inventors: Marvin Whiteman, Timothy Jaszkowiak

Publication number: 20060207063Abstract: A vibration-dampening, height-adjustable handle for a power tool. Embodiments include a handle assembly connected to a shaft or frame via a plurality resilient fittings. The resilient fittings are arranged to conduct roll, pitch, and yaw forces sufficient to control the power tool. In some embodiments, the handle assembly rotates about at least one resilient fittings, and the height of the handlebar portion of the handle assembly is controlled by adjusting the distance between the shaft and another resilient fitting.Type: ApplicationFiled: January 13, 2006Publication date: September 21, 2006Applicant: Multiquip. Inc.Inventors: Timothy Jaszkowiak, Marvin Whiteman

Patent number: 7036416Abstract: Embodiments of an punch machine and a quick-change die assembly are shown and described. The die assembly may be quickly installed and removed from the punch machine, without bolting or unbolting of either machine housing or the die assembly itself. The die assembly is slid into the machine through a hole in the machine housing and into a position which mates part of the die assembly with the push-bar. A clamp, with a handle outside the machine, is then pivoted against the die assembly. The push-bar is adapted to be self-supporting without being bolted to the die assembly, keeping the push-bar in place without manual adjustment and alignment. The die assembly preferably includes a die, pin retainer, and punch pins, and preferably includes a flexible, pivotal, or hinged pin strap to secure the pins to the retainer.Type: GrantFiled: June 15, 2004Date of Patent: May 2, 2006Assignee: Performance Design, Inc.Inventors: Marvin Whiteman, Wayne Malmstrom

Patent number: 6789453Abstract: Embodiments of features for a paper punch machine are shown and described. Preferably, these features, which may be called “accessories” whether they are built-in original equipment manufacture or retrofit equipment, assist in proper paper alignment and punch control. A first accessory is an improved paper stop that is both grossly-adjustable and finely-adjustable, by a preferred combination of a biased sliding mechanism, followed by a fine-tuning mechanism gradually laterally moving the paper stop by causing a threaded shaft to rotate after the paper stop is already in the preferred “gross-adjustment” position. This way, the paper stop is brought close to the proper marking on the housing appropriate for a particular paper or die assembly, and then exact adjustment may be made in very small and precise amounts.Type: GrantFiled: May 16, 2002Date of Patent: September 14, 2004Assignee: Performance Design, Inc.Inventor: Marvin Whiteman
