The rotating steel tube was tapered and mounted on an angle. This pier seems to have held the higher end of the tube.

Description 

In 1908, John T. Jones invented a process to refine low-grade iron ore into a viable product. He built a long, steel tube, lined with fire brick, that rotated while heated. Although this particular prototype ran into severe difficulties and was dismantled, lessons learned helped refine the process as time went on. All that remains are these silent reminders of Jones' efforts.
