1. Rod bending apparatus comprising:

  • (a) a rod supporting means against which the bar to be bent may be positioned;

    (b) a movable mandrel positioned on one side of said rod supporting means, said mandrel having a lower actuator portion extending forward and beyond the said mandrel;

    said lower actuator portion having an opening extending through a lower portion thereof;

    (c) a power means supported adjacent to said rod supporting means and said movable mandrel, said power means having a power thrust bar extending therefrom adapted to extend through the said opening in said lower actuator portion of said mandrel, said thrust bar having a threaded portion extending from the end most remote from said power means and extending toward said mandrel;

    (d) an adjusting means having a threaded opening therein which threads fit the threads on said thrust bar, said adjusting means being capable of adjusting and controlling the position of said mandrel on said thrust bar;

    (e) two pivotal arms supported on said rod supporting means and pivotal on pins projecting upward from said bar supporting means, each of said arms having a rotatable roller extending from said arm and capable of pressing against a rod positioned on said rod supporting means between said mandrel and said rollers;

    whereby the same power stroke of the power thrust bar is capable of moving the mandrel against the rod positioned on said rod supporting means between the mandrel and the rollers and with the movement of the mandrel the lower extended portion of the mandrel is capable of pressing the end of each said arm thereby causing the arms to pivot on said pins and press said rollers against the opposite side of said rod from said mandrel.
