  • Patent number: 10961729
    Abstract: A reinforcing bar binding machine reduces restrictions on a moving direction in pulling out from a reinforcing bar bound with a wire. The reinforcing bar binding machine (1A) includes a curl guide unit (5A) that winds a wire (W) around a reinforcing bar (S), a wire feeding unit (3A) that feeds the wire (W), and a binding unit. A first guide unit (50) curls the wire (W) fed by the feeding unit (3A) and a second guide unit (51) guides the wire (W) fed from the first guide unit (50) to the binding unit (7A). The second guide unit (51) includes a fixed guide unit (54) that restricts a position in a radial direction of the wire (W) wound around the reinforcing bar (S) and a movable guide unit (55) that restricts a position in an axial direction of the wire (W).

    Abstract: A wire feed amount detection mechanism is configured by magnets mounted at an outer peripheral surface of a V-grooved drive gear of a wire feed mechanism and a magnetic sensor mounted on a body. A reinforcing bar winding turn number-setting switch is provided on the body. A control portion controls a wire feed amount of a wire feed mechanism based on a set value of the reinforcing bar winding turn number-setting switch. The number of turns of the wire around reinforcing bars can be arbitrarily set, for example, to any one of 1 to 4, and the binding can be effected with a binding force corresponding to a strength required by binding portions. As a result, with respect to those binding portions requiring a low binding force, the binding is effected with a smaller turn number, so that the amount of consumption of the wire can be saved, and besides those pipes (such as electric wiring pipes and hot water pipes) which are lower in strength than the reinforcing bars can also be bound together.

  • Patent number: 7290570
    Abstract: A twist attachment device which is suitable for attaching a segment of fence wire such as a run of barbed wire to a fence post in the construction of wire fences. The device includes a frame within which is rotatably mounted a pair of spaced-apart wire twist gears each having a wire notch and a wire segment opening adjacent to the wire notch. A drive mechanism operably engages the wire twist gears to rotate the wire twist gears in the housing. In operation, an attachment wire segment is extended through the registering wire segment openings of the respective wire twist gears, after which a fence post is extended between the spaced-apart wire twist gears. The segment of fence wire to be attached to the fence post is then inserted into the registering wire notches of the wire twist gears.

  • Patent number: 7124786
    Abstract: Linesman type pliers (10) that have provisions for splicing wires together. The pliers (10) have a right body (20) with a first jaw (22) on one end, and a handle (24) on the other end, and a pivotal bore (26) in-between. The first jaw (22) includes a truncated, tapered recess half (28) that is configured to receive an outward-extending stop and the provisions for gripping wire. A left body (32) has a similar jaw, handle, bore and truncated tapered recess half, except with an outward-extending stop (38) on the inner end. A pivot pin (42) is jointly disposed within bores (26) and (36), thus forming a solid-joint that arcuately swivels the right body (20) and left body (32) together into parallel and adjacent alignment. When the jaws are closed a complete, annular, truncated tapered recess (44) is formed that allows insertion of a number of stripped wires that form a twisted splice when the pliers are manually rotated around the stationary wires.

  • Patent number: 7104287
    Abstract: Wire-untwisting tools and tool bits are disclosed. The wire-untwisting tool comprises a tool body, a movable member, and a spring. The tool body has a first channel extending inwardly from a first surface and a second channel extending inwardly from a second surface. The movable member includes a third channel, and is positioned within the second channel to move therein between an open position, in which the first and third channels are substantially aligned and contiguous, and a gripping position, in which they are not. The spring bears between the tool body and the movable member so and biases the movable member toward the gripping position. A pair of twisted wires inserted into the aligned channels of the tool body and the movable member when the movable member is pushed into the open position will be gripped for untwisting when the movable member moves back to the gripping position.

  • Patent number: 6962173
    Abstract: A wire handling tool element includes a cylindrical body having a J-shaped hook on one end and a drill bit-type element on a second end. A wire is pulled out of a jacket containing a plurality of wires by attaching one end of that wire to the cylindrical body and attaching the cylindrical body to a power tool, such as a power drill, and causing the wire to be wrapped around the cylindrical body. This wrapping pulls the wire out of the jacket. Once the wire is pulled out of the jacket, one end of the wire is attached to the J-shaped hook and the other end of the wire is held against rotation and the power tool is operated thereby twisting the wire about its longitudinal axis. A plurality of wires can be attached to the J-shaped hook to be twisted together when the power tool is operated.
