Publication number: 20080196910Abstract: A power hand drill or other power tool includes at least one of a detachable non-contact voltage sensing device and a detachable subsurface object locator for detecting the presence of an object beneath a surface being probed with the locator. The drill has a housing with a flat accessory mounting surface including coupling elements for coupling the sensing module to the drill. The accessory device includes a mating coupling element to engage with the coupling element in the drill housing. The non-contact voltage sensing circuitry includes sensing circuitry contained within a housing with an antenna that is positioned opposite a tool head of the power tool, and an indicator mounted to the module for indicating the presence of a voltage.Type: ApplicationFiled: January 30, 2008Publication date: August 21, 2008Inventors: Patrick J. Radle, Daryl C. Brockman, David L. Wiesemann, George R. Steber, Thomas M. Luebke

Patent number: 7374150Abstract: A fish tape reel has an ergonomic pistol grip and ergonomic hand grips at an inner periphery of a hollow housing. Fish tape is wound into the housing cavity by rotating the housing with respect to the pistol grip. This can be done manually by grasping the interior handle(s) or using a ratcheted winder that fits into the housing opening and has a lever handle for ratcheting the housing. The reel is held with the housing beneath the pistol grip which has a retainer shoe slidably sandwiched between halves of the housing. The pistol grip is positioned behind a vertical center line of the reel so that the weight of the reel is balanced in a neutral position in which the pistol grip can be grasped with the user's wrist being essentially straight and horizontal. A method of assembling the reel is also disclosed in which the fish tape is attached and wound after the housing is assembled.Type: GrantFiled: August 6, 2004Date of Patent: May 20, 2008Assignee: Actuant CorporationInventors: David L. Wiesemann, David A. Huebschen

Publication number: 20080042657Abstract: A multi-scanner device having a detection unit and an outlet tester that can be selectively connected together for convenient use and easy storage. Preferably, a plug on the outlet tester is inserted into a non-functional socket located on the detection unit to form a multi-scanner device with a detachable outlet tester.Type: ApplicationFiled: August 17, 2007Publication date: February 21, 2008Inventors: Patrick J. Radle, Daryl C. Brockman, David L. Wiesemann

Patent number: 7044415Abstract: A winder insert for a fish tape reel fits into a center opening of the fish tape reel and engages an inner periphery of the reel. The insert has an attachment member, which can be a multi-sided socket for example, that is engaged by a removable handle or lever member to rotate the insert and in turn the reel with respect to a reel handle grasped by the user so as to wind and/or unwind fish tape in the reel. In one preferred form, a roller clutch is pressed into a center opening of the insert about a drive shaft that is rotated by the handle. The handle and shaft can be rotated in one direction to engage the clutch and thereby rotate the reel. Rotating the winder handle in the opposite direction overruns the clutch so that the handle can ratchet back to the original position without unwinding the reel. The winder insert removably snaps onto the reel.Type: GrantFiled: February 12, 2004Date of Patent: May 16, 2006Assignee: Actuant CorporationInventors: David L. Wiesemann, David A. Huebschen, Debra L.

Patent number: 6844819Abstract: A hand tool which provides an alarm signal to a user as the tool approaches a live electrical wire is disclosed. The hand tool comprises a conductive tool head and a non-conductive handle. A non-contact voltage sensing circuit is provided in the handle of the tool. As the tool head approaches a live electrical wire, the non-contact voltage sensing circuit detects the voltage across the air gap between the tool head and the electrical wire, triggering an alarm circuit. The alarm circuit provides a visual or audio signal to the user.Type: GrantFiled: March 24, 2004Date of Patent: January 18, 2005Assignee: Actuant CorporationInventors: Thomas M. Luebke, David L. Wiesemann, George R. Steber

Patent number: 6844713Abstract: A pocket-sized object finder has a compact housing containing a battery, circuitry and a capacitor plate for detecting an object hidden behind a wall. The battery powered circuitry includes multiple signal indicators that illuminate in a serial manner when the object is being detected. The signal indicators are successively tapered and are mounted at a front side of a tapered end of the housing. The capacitor plate is disposed in the housing along its rear wall and is responsive to variations in capacitance that occur as the object finder is brought near and over the object. The compact housing defines a cavity with a width that is no more than two inches and one third its length. A removable access door, with a pocket clip, at an end opposite the signal indicators allows access to the battery within the housing cavity.Type: GrantFiled: June 9, 2003Date of Patent: January 18, 2005Assignee: Actuant CorporationInventors: George R. Steber, Thomas M. Luebke, Stephen J. Skeels, David L. Wiesemann

Patent number: 6812685Abstract: An electrical testing device has non-contact AC voltage sensing, single probe contact AC voltage testing and voltage metering functions. Non-contact voltage sensing is used to detect the vicinity of a live AC conductor and single probe contact sensing is used to determine which conductor of a number of conductors in the vicinity is live. More specific information about the magnitude of the voltage can then be determined using both contact probes. The electrical testing device automatically determines the type (AC or DC) and polarity (if DC) of a voltage applied to test terminals, and provides an indication of the voltage range (AC or DC), without the need to operate any switches or other electrical actuators.Type: GrantFiled: February 13, 2002Date of Patent: November 2, 2004Assignee: Actuant CorporationInventors: George R. Steber, David L. Wiesemann, Thomas M. Luebke

Patent number: 6684439Abstract: A hand held wire stripper includes a feature for aiding in attaching a connector to a stripped end of a coaxial cable. The wire stripper includes first and second lever members joined together by a pin, each with an elongated handle and an offset jaw having an oblique cutting edge. The jaw of the first lever member includes an opening sized to receive a coaxial cable connector and a hexagonal recessed surface about the circumference of the opening sized to receive the hexagonal nut section of the coaxial cable connector. The jaw of the second lever member includes an opening of lesser diameter that receives the stripped end of the center conductor of the coaxial cable and is located so it can be substantially concentric with the opening in the first lever member when the wire stripper is closed. The stripper recesses may be hex shaped with straight edges defining the recess. A method of stripping an insulated conductor is also disclosed.Type: GrantFiled: August 30, 2001Date of Patent: February 3, 2004Assignee: Actuant CorporationInventors: Dennis J. Jeske, Robert W. Kruse, Allen W. Montgomery, David L. Wiesemann
