ABSTRACT:
A manually operated wire or cable bending apparatus comprising a support assembly for supporting a forming die at one end thereof. A drum assembly comprising a pair of spaced apart interconnected weighted members is mounted on the support assembly, one such weighted member provided with graduations thereon from 0.degree. to 360.degree. on one end face thereof, whereas the other said weighted member having a means for swivelly securing a measuring tape which is adjustably mounted on said support assembly. The forming die comprises a forming block pivotally mounted on a rotatable handle, the forming block cooperating with a fixed grooved forming die to bend a wire or cable positioned between the said forming block and said grooved forming a die when a handle to which the said forming block is pivotally mounted thereon is rotated counterclockwise. A back-up support is rigidly secured to said support assembly and serves to properly align the wire or cable to be bent by the said forming block and grooved forming die. A compass card having graduations thereon from 0.degree. to 180.degree. is frictionally mounted on a shaft to which the aforesaid handle is secured. The shaft extends through the said fixed grooved forming die and a pointer fixedly secured to said support assembly extends to a position in close proximity to said compass card to indicate the degree bend applied to a wire or cable bent with the foregoing apparatus.
