Abstract: A method and apparatus applicable with transformers having a magnetic circuit which is supported horizontally within a tank or shell made up of upper and lower parts, wherein a two-piece bar-like member assembly supported at its extremities on edges of the lower part of the tank, along with a conventional T-shaped beam support member is utilized to support the core laminations in such a manner that wedges used to fix in place the windings of the circuit can be readily adjusted beneath the area of the T-shaped beam. The bars are tensioned in place by adjustment of the wedges between the lower area of the windings and the tank sidewalls. The beam is then placed on the edges and anchored thereon.
