Abstract: A handheld wire twisting tool for making a wire conductor twisted splice connection. The tool includes a winding disk having a plurality of wire insertion apertures therethrough in an annular array for respective insertion therethrough of the stripped ends of wires to be twisted together. A finger engagement handle extends from the winding disk in substantially the same plane as the winding disk and extends also substantially radially from the annular array of apertures for manipulating the disk with the handle by one's finger for wire winding by rotating the winding disk about the axis of the annular array of apertures. A wire depth stop disk is also provided in spaced relationship from and secured in parallel to the winding disk and overlies the annular array of the apertures whereby wire ends inserted through the apertures will engage in the inside surface of the depth stop disk to meter the proper depth of penetration for winding.

Abstract: A hand-held wire twister including an upper portion having a handle engageable by an operator for imparting a twisting action to the wire twister. A lower portion has a wire strand engaging head that is coupled to the handle by an extension shaft. The wire strand engaging head flares outward from the extension shaft so that a perimeter of the head is greater that a perimeter of the shaft so that the head establishes a wire engaging portion of the wire twister. The wire engaging portion has at least two wire receiving channels cut thereinto for engaging at least two wire strands to be connectively intertwined by rotational motion of the wire twister; each channel engaging one or more wires. Each of the channels extends from an opening at the perimeter of the head toward a center of the head.

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.

Abstract: Apparatus for wire wrapping or tying is disclosed, wherein an inner sleeve is telescopically positioned within an outer sleeve, each of which is provided with a handle for imparting relative rotational movement. The wire tie apparatus is adapted to receive wire which is wrapped an object to be tied. The wire passes through the outer sleeve then through the inner sleeve. Apparatus is provided to fricitionally lock the wire at some point along the length of the inner sleeve. Rotation of the inner sleeve relative to the outer sleeve in accordance with specially prepared ends of both the inner and outer sleeves causes the wire to twist and to become wrapped tightly around the object to be wrapped. Further relative rotation causes inelastic extension of the wire and subsequent breakage of the same somewhere along the length of the twisted portion thereof.

Abstract: A unitary multi-purpose tool cuts, strips and twists together wires for example in preparation for the installation of insulating cap-type twist-on wire connectors.
