  • Patent number: 7295130
    Abstract: 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 tool head and coupled to a handle. A non-contact voltage sensing circuit is provided in the handle of the tool. As the tool 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.

  • Publication number: 20070187659
    Abstract: 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.

  • Publication number: 20070159739
    Abstract: A hand tool and an accessory which provide an alarm signal to a user as the tool or accessory approaches a live electrical wire are disclosed. The hand tool or accessory include a non-contact voltage sensing circuit. As the tool or accessory approaches a live electrical wire, the non-contact voltage sensing circuit detects the voltage, triggering an alarm circuit. The alarm circuit provides a visual or audio signal to the user. The hand tool can be selectively coupled to the tool head.

  • Publication number: 20050029383
    Abstract: 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.
