"Vintage Machinery" entry for Hildreth Brothers
Description:
This horse power was a successful product for Burt, Hildreth & Company. That firm began in 1855 as Burt, Wright & Company, then became G. E. Burt & Company, then in or shortly after 1864 it became Burt, Hildreth & Co. Hildreth left the partnership in 1880 to join his brother Stanley (who is a witness on this patent) to form Hildreth Brothers. That firm went on to substantially greater success then Burt's firm. About George Burt, the book "History of the Town of Harvard, Massachusetts: 1732-1893" tactfully said, after noting his numerous patents: "It is rare that inventive talent is accompanied by those business qualifications that ensure large financial success, and Mr. Burt is not exceptional in this respect."
