Beschreibung
Zusammenfassung:	Apparatus for inductively hardening workpieces, such as crankshafts, which have different surface parts which are heated by different shaped inductors which partially surround the surface to be hardened. The apparatus includes means for mounting a number of workpieces for rotation and for indexing between a hardening position and a position in a quenching bath, a plurlaity of inductors mounted on an indexing spider which is in turn mounted on a plate with a transformer, that plate being moveable toward and away from the workpiece and along the workpiece axis. The indexing spider is rotateable to present different inductors according to a predetermined program and movable along its axis of rotation to couple and uncouple an inductor in a hardening position from the transformer.
