This firm was one in a series of Philadelphia makers of woodworking machinery. In 1869, E. C. Tainter—formerly the head of J. A. Fay & Co.'s Worcester, MA operations, and who operated under his own name in Worcester—joined the firm of Power & Davis, with the resulting firm being named Power, Davis & Tainter. By 1876 the firm was known as Power, Tainter & Co. At some point it became E. C. Tainter & Co., and then in 1878 that firm was bought out by Goodell & Waters.
