NOTE: This Machine Was Designed By Aronson For Babcock 
  & Wilcox So The Turning Rolls Could Be Used Under 
  Vertical Boring Mills, Radial Drills, Horizontal 
  Boring Mills ETC. Twin Driver Turning Rolls Use One 
  Driven Wheel On Each Roll Stand. One Of These Driven 
  Wheels Has Two Final Gear Drive Worm Gears On Each 
  Side Of The Axle. Thus The Two Pinions Work In  
  Opposite Directions To Eliminate Backlash.
