In 1911 The John A. White Co. was purchased by Dover, NH, entrepreneur Joel Sheppard, who renamed the business to Dover Machine Works. Sheppard then purchased Hobbs Manufacturing Co., which had, a few years earlier, bought out Witherby, Rugg, & Richardson. Dover and Hobbs were merged to create National Woodworking Machinery Co.
