- 0 - PORTABLE CONDUIT BENDING APPARATUS Abstract of the Disclosure A portable electric driven conduit bender which accommodates rigid, IMC and thinwall conduit of various sizes in a single setup includes a rotatable, cone-shaped bending shoe, and a roller assembly for supporting conduit during bending. The bending shoe has a pair of arcuate-shaped die portions positioned diametrically opposite one another for shaping rigid and IMC conduit, and thinwall conduit, respectively, and each die portion has a plurality of bending grooves formed therein for accommodating various conduit diameter sizes. The roller assembly includes a roller unit for larger diameter conduit that has a split forming roller and a solid backup roller located side-by-side which cradle the conduit during the bending operation. One of the halves of the split roller is adjustable in its axial direction between a closed position for supporting thinwall conduit and a separated position for supporting rigid conduit. A lever arm is used to rotate an eccentric which moves the roller unit into an operation position for bending and an in- operative position for inserting or removing conduit. The lever includes a roller handle which acts as a backup roller for bending smaller diameter conduit.
