Birdsall portable double cylinder engine.
Birdsall
The Birdsall Company of Auburn, N.Y. manufactured this portable steam engine in 1890. Founded in Penn Yan, N.Y. by Hiram and Edgar M. Birdsall in 1860, the company originally manufactured threshing machinery and horse-powered implements. In 1874 Birdsall began manufacturing portable steam engines, and in 1881 the company moved to Auburn, N.Y. At this time Birdsall also introduced a steam traction engine. Birdsall reorganized under new management in 1886, but the company closed shop in 1893. There are indications the company operated at some point in Newark, N.Y., a small town roughly 50 miles northwest of Auburn.
In 1929 Henry Ford purchased this portable steam engine for the Edison Institute, and displayed the engine in the Henry Ford Museum & Greenfield Village in Dearborn, Mich., until 1985. At that time, it was sold at auction. Records from the museum say it was sold due to the museum's possession of a second Birdsall, making this engine "redundant."
Originally drawn by horses, these engines were used to power saw mills, shingle mills, threshing machines, dynamos, pumps and even overhead line shafting. Ross bought the Birdsall from Charles Chiarchiaro of Waldoboro, Maine. Kiwi Carriers transported the Birdsall from Maine to Sammamish, arriving on Aug. 14, 2001.
Technical Details Birdsall Portable Steam Engine
This is a truly fine example of a circa 1890 6 HP American portable steam engine. The engine appears to be in very close to new condition, with no sign of use other than for display purposes. When acquired from the Ford Museum there was no sign that the engine had been fired, and it was possibly acquired by Ford in such condition. It came complete with the original maple wheel chocks used while on display in the Ford Museum.
