1895 (8 Inch) Denney Improved Hot Air Engine by (American Machine Co.) - $5,000 - (Eliot, ME)
This is Brad Eisner's Denney Full Size Hot Air Engine. This is the engine that my dad copied in 1/4 size to make casting patterns for the model Denney Hot Air Casting Set that I also have for sale on another eBay listing. This engine is Serial Number 1064 and was patented on April 23, 1895. Just by coincidence my dad Bradford Eisner's birthday is also April 23, however he was born in 1915 not 1895. There are only about 20 known examples of the Denney Improved Hot Air Engine in existence today. Search "Denney Hot Air Engine" or "American Machine Hot Air Engine" or "Wade Eisner" for online videos of both the full size and model Denney Engines running. The stove bottom was broken and repaired as can be seen in the pictures. It was rebuilt using a large steel or cast iron pipe.
