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. The wire twist gears rotate in concert with each other to wrap the attachment wire segment around the fence wire segment on opposite sides of the fence post, in such a manner that the fence post is interposed between the attachment wire segment and the fence wire segment and the wire segments tightly engage the front and rear sides of the fence post. The drive mechanism for rotating the wire twist gears may be a hand-operated drill or an electric motor, for example.
