Patent number: 11827394Abstract: A cable tie application tool is described that includes an electro-mechanical tensioning system. When the electro-mechanical tensioning system is controlled by a processor to tighten a cable, a reactionary force through a drive nut that is pivotally mounted to a tension bar can be monitored and measured by a strain gauge, a load cell, or other sensing system. This reactionary force is an indication of tension on the cable tie and is monitored by the processor until the tension reaches a predetermined tension, at which point, the processor causes a motor in the tensioning system to stop increasing the tension on the cable tie. The processor activates a cut-off system to cut the cable tie that has been tightened to the predetermined tension.Type: GrantFiled: October 26, 2022Date of Patent: November 28, 2023Assignee: HellermannTyton CorporationInventors: David A. Hempe, Roger D. Neitzell, Peter David Joseph, Blaine G. Kuehmichel, Jonathan Paul Loeck, Nicholas Alexander Matiash

Patent number: 7658012Abstract: A reciprocating saw generally includes a housing and a motor supported by the housing. A spindle is mounted for reciprocation relative to the housing, the spindle having a front end for supporting a saw blade and being movable through a cutting stroke and a return stroke, and the cutting stroke may have a stroke length. A rotary member may be supported for rotation about a rotary axis. The saw may further include an adjusting assembly operable to adjust the stroke length of the spindle. Also, the saw may include a counterweight supported for movement relative to the housing, a movement of the counterweight substantially balancing at least a portion of movement of the spindle, and an adjusting assembly operable to adjust the movement of the counterweight.Type: GrantFiled: December 22, 2003Date of Patent: February 9, 2010Assignee: Milwaukee Electric Tool CorporationInventors: Thomas P. James, Roger D. Neitzell, David A. Hempe

Patent number: 7521826Abstract: A method of assembling a power tool, a power tool, a method of assembling an electrical device, and an electrical device includes a switched reluctance motor. The electrical device is preferably a hand-held power tool, however, any type of electrical device that includes a switched reluctance motor may benefit from any number of aspects of the invention. In one independent aspect, the invention provides a construction that reduces tolerance stack-up. In another independent aspect, the invention provides a self-contained electronics package that plugs into a switched reluctance motor to provide control operation of the switched reluctance motor. In another independent aspect, the invention provides enhanced cooling that increases the efficiency of the electrical device using a switched reluctance motor. In another independent aspect, the invention provides an encapsulated magnet that allows for contaminant free motor control over the life of the SR motor.Type: GrantFiled: January 13, 2006Date of Patent: April 21, 2009Assignee: Milwaukee Electric Tool CorporationInventors: David A. Hempe, Gary D. Meyer, Roderick N. Ebben, Jeffrey M. Brozek

Publication number: 20060104735Abstract: Carrying systems, connecting systems and methods. The system connects a power tool and a component. In some constructions and in some aspects, the power tool includes a housing and a U-shaped receptacle defined by the housing. In some constructions and in some aspects, the component includes a stud selectively engageable with the receptacle to connect the power tool and the component. A locking mechanism is positioned within the receptacle and includes a cam. The locking mechanism is engageable with the stud to restrict movement of the stud with respect to the receptacle. The stud includes a recess at an end of the stud. The cam is selectively engageable with the recess to retain the stud within the receptacle. The cam is movable between a lock position and a released position. In the locked position, the cam extends into the recess and engages the stud. In the released position, the cam is retracted from the recess and is disengaged with the stud.Type: ApplicationFiled: March 14, 2003Publication date: May 18, 2006Inventors: Jeffrey Zeiler, Thomas James, Pamela Stegehuis, David Hempe, Burton Yanke
