Thorne Multiple Boiler

 

This is what a Thorne Multiple boiler looks like when left out in the rain for twenty years.  A good whole brochure for this boiler can be seen on Don Hoke’s Virtual Steam Museum website.  It was made in Chicago in the 1920’s as a replacement for the Stanley boiler having the same dimensions and the same surface area for heat exchange.   Thorne Multiple Boiler
  It weighed 200 pounds more.  There was a lot of welding in this construction and many cast parts.
