Abstract
A hand held wire bending tool is provided having three handles two of which operate wire gripping jaws while the third is swung through a short arc to form either a right angle or a U-bend in a wire. The tool is particularly useful in providing ceiling suspension wires with loops suitable for supporting a ceiling grid network in a predetermined horizontal plane.

A hand-held wire bending tool comprising:
- a first handle having a U-shaped yoke at one end thereof;
- a plier-like tool having second and third handles pivotally connected together rearwardly of a pair of wire gripping jaws integral with a respective one of said second and third handles and having at least one set of wire gripping grooves extending crosswise of the inner faces thereof;
- and
- shaft means extending loosely through each of said jaws between said grooves and said pivot connection of said handles with the ends thereof mounted in a respective one of the legs of said U-shaped yoke whereby said first handle is operable to bend a wire gripped in said grooves through an angle of 90.degree. C.

A tool for making at least a right angle bend at a predetermined point in a ceiling suspension wire anchored to an overhead support comprising:
- a pair of wire gripping jaws each integral with a respective handle pivotally connected together rearwardly of said jaws for pivotal movement toward and away from one another and which handles are adapted to be held in one hand while gripping a wire extending crosswise of said jaws;
- a third handle having a yoke at one end straddling said jaws and pivoted thereto on a shaft extending loosely through openings crosswise of each of said jaws between the wire gripping surfaces thereof and the pivot connection between said first mentioned handles;
- and
- the jaws of said tool being adapted to grip a suspended wire above but immediately contiguous to said predetermined bending point and with the yoke of said third handle positioned below said jaws and alongside said wire and said third handle and the yoke thereof then being pivotable against said wire and through an arc adequate to form a right angle bend in a gripped wire.
