Abstract

See full text

A preheater for heating either intermediate or small size electrical wire includes left and right inductors, each having a longitudinal passageway through which the wire to be heated is passed, one inductor being fixedly mounted on a mounting plate with its passageway vertical and the other inductor being pivotally mounted on the mounting plate so that its passageway can be either positioned vertically or tilted at an angle from vertical, a lower wheel rotatably mounted on the mounting plate below the inductors, a first upper wheel sized for use with intermediate diameter wires and a second upper wheel sized for use with small diameter wires, only one of the upper wheels being mounted on the mounting plate at a time. When intermediate size wire is being run, the pivotally mounted inductor is positioned with its passageway vertical and the first upper wheel is rotatably mounted on the mounting plate above the inductors and vertically aligned with the wheel. When small size wire is being run, the pivotally mounted inductor is tilted and the second upper wheel is rotatably mounted on the mounting plate above the inductors and aligned with the tilted inductor. In use, the wire being heated passes around the upper wheel, through one inductor, around the lower wheel, through the other inductor and then around the upper wheel again.
