Abstract: PORTABLE CONDUIT BENDING APPARATUS 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 inoperative position for inserting or removing conduit. The lever includes a roller handle which acts as a backup roller for bending smaller diameter conduit.
