Vintage Machinery entry for Buffalo Pitts Co.
Description:
A catalog from Pitts Agricultural Works features "Perry's Patent American Horse Power. Patented in the United States, April 22d, 1862 (35,062 and 35,063); also, July 21st, 1863 (39,324); and again July 21st 1863 (39,325); also, September 24th, 1867 (69,243)." We assume that this 1872 improvement would have been used by The Pitts Agricultural Works as well; this firm would became the Buffalo Pitts Co.
