Patent number: 8281871Abstract: A system, and a method of using a system, for controlled tool operation. The method includes providing a tool used in a force application such as a such torque application. The tool communicates with a controller which can communicate with the tool, and to a display in communication with the tool and the controller. The controller can be programmed with operational information about a tool operation. Information related to the operational information is displayed to a user during use. Service information including at least information about an amount of force applied during use is recorded and stored in the controller. Also disclosed is a computerized system for controlled tool operation which sends operational instructions to the tool before use and retrieves service information from the tool after use.Type: GrantFiled: May 27, 2011Date of Patent: October 9, 2012Assignee: Snap-On IncorporatedInventors: Brian J. Cutler, David Duvan, Gary Keefe, Denny Atkinson, David R. Costantino

Patent number: 8171828Abstract: An electromechanical wrench has a housing that has a working end and a gripping end, with a driver positioned at the working end, and a handle positioned at the gripping end. The wrench further includes a click wrench emulator mechanism provided at the handle. A method of using an electromechanical wrench to secure a fastener using angular measurement without the need for establishing a zero reference point, and allowing for ratcheting, is also provided. A method of counting the number of fasteners secured by an electromechanical wrench during a wrenching job is further provided.Type: GrantFiled: December 9, 2009Date of Patent: May 8, 2012Assignee: Digitool Solutions LLCInventors: David Duvan, Tony Duvan

Patent number: 7107884Abstract: An electronic torque wrench has a tubular core with elongated apertures therein which respectively removably receive user interface assembly and power assembly modules, the modules being exposed through openings in a surrounding grip sheath. A workpiece-engaging head is coupled to a beam member which may received in a tapered opening in a shim member received in an end of the tube. A sensor on the beam member is connected by wires extending to the user interface assembly, which in turn has a display device producing a bar graph display indicating the proximity of a measured torque value to a preset torque level.Type: GrantFiled: September 28, 2004Date of Patent: September 19, 2006Assignee: Snap-on IncorporatedInventors: Brian Cutler, David Duvan, Charles Davis, Zoltan Pavlakovich

Patent number: 6968759Abstract: An electronic torque wrench has inner and outer telescoping housing portions and a battery tray assembly telescopically receivable in the inner housing portion and a bezel assembly receivable in an aperture in the outer housing portion and interconnected with the housing portions and the battery support assembly by a single fastener. The bezel assembly carries torque measuring circuitry including a microcontroller, and a four-key pad including arrow keys for incrementing and decrementing a preset torque level at any time, an on/zero key and a units key for toggling among plural different units of torque measurement. The preset torque level is displayed until torque is applied or a key is pressed and can be changed and displayed at anytime.Type: GrantFiled: November 13, 2002Date of Patent: November 29, 2005Assignee: Snap-on IncorporatedInventors: Thomas P. Becker, David F. Brekke, David Duvan, Rolf Segger
