Abstract
A wire bending ceiling tool for cutting, bending and tying metal hanger wires such as those used for hanging false ceilings in buildings. The tool includes a pair of handles connected to a jaw having gripping members for holding a wire to be bent. One gripping member is a block to bend the wire around. The other gripping member is a surface to which a third handle is pivotally mounted. The third handle has a wire guide which guides the wire around three corners of the bending block to bend the wire into two right angles and a 45 degree angle when the third handle is pivoted creating a saddle to carry the channel beams, and which guides the wire around a corner of the bending block to bend the wire into one 90 degree angle when the third handle is pivoted creating a hook to attach to a main runner, an anchor or embed in concrete. The third handle detaches converting into a tying handle for tying a wire. The tying handle includes a wire guide operating in coordination with a hole for tying a hanger wire. Wire cutting edges located on the jaws cut a hanger wire when the gripping handles are squeezed together. Simultaneously pulling the third handle assists the wire cutting edges to cut the wire. The jaw hinge includes an indexed scale to determine proper bend location for the desired ceiling height.

- This invention is a wireworking implement used for shaping lengths of wire by bending, crimping and looping, with such shaped lengths of wire used for hanging false ceilings in high-rise building construction.
- Various devices are known for bending strap and wires as exemplified in U.S. Pat. Nos. 4,091,845, 3,662,580, 3,604,244 and 1,316,257; however, none of these appear of similar design and geometry, nor do they appear suitable to correctly perform the below desired functions. As an example, the device exemplified in U.S. Pat. No. 4,091,845 does not include a removable tying handle for tying a wire.
- This invention relates to a novel wire bending ceiling tool adapted to determine appropriate bend location on a suspended false ceiling hanger wire relative to desired ceiling height; and adapted to determine appropriate bend location on a suspended false ceiling hanger wire relative to finish line, split line or iron line; and adapted to grip and bend the free end of the wire to attach to the false ceiling frame; and adapted to grip and tie the free end of the wire to the false ceiling frame; and adapted to grip and bend the wire to attach to an anchor or embed in concrete; and adapted to be lightweight, easily used and easily carried by hand.
- The drawings constitute a part of the specification and include an exemplary embodiment of the present invention and illustrate various objects and features of the ceiling tool.

- In building construction and renovation, elongated vertical wires with free ends are commonly used as hangers to support a frame for the installation of false ceilings. Such false ceilings are often suspended below the successive floor structures in modern multiple story commercial buildings to cover exposed utility and heating conduits. False ceilings may also be relied upon to lower high ceilings for aesthetic purposes or to meet building fire code in older buildings. Metal lath for plastering operations, plasterboard or drywall may be secured to the frame to form the completed installation.
- The frame used for hanging such false ceilings normally consists of a series of elongated channel beams having a 1½ inch web and ½ inch flanges. The channel beams are installed on their flanged sides with webs vertically directed. Metal furring strips to which the metal lath for plastering operations, plasterboard or drywall is secured to the channel beams. The upper end of the hanger wire is suitably anchored to the “true” ceiling and the lower end wrapped securely around and tied to one of the channel beams to suspend the beam from the “true” ceiling. For installation that meets or exceeds current seismic codes, the wire must be bent in a precisely located square angled U-shape with dual right angles, forming a saddle shaped holder in which the beam is subsequently positioned at the appropriate height, commonly referred in the construction trades as “splitline” and a third precisely located sharp angle in preparation of the following wire tying. The free end of the wire is then wrapped around the attached suspended wire, looped around the channel beam again then brought upwardly and twisted around the attached suspended wire forming a distinctive tie commonly known in the trade as a “saddle tie.”
