Abstract
Handheld wire twisting apparatus can be readily applied to a working section of an elongated electrical harness to be twisted, operated to impart twist to the desired extent, then removed after the twist has been secured in the harness. It includes a housing with an integral handle. An internal cylindrical bearing surface defines a transverse axis and includes an inlet into a bearing cavity which is a hiatus in the bearing surface. A c-shaped cylindrical wire twisting head is journaled on the cylindrical bearing surface for rotation about the transverse axis and defines a transverse passageway for reception of a wire bundle to be twisted. The wire twisting head has a peripheral gap for reception of the wire bundle into the transverse passageway when the peripheral gap is coextensive with the inlet in the housing. A gear train is rotatably mounted between opposed plate members comprising the housing for rotating the head, selectively, in first and second directions about the transverse axis and a ratchet mechanism selectively preventing rotation of the head in the first and second directions. The wire twisting head includes a c-shaped cylindrical drive wheel, a c-shaped cylindrical …
