Incorporated in 1868, Athol Machine Co. was acquired in 1905 by Laroy Starrett. He had worked for them prior to that time and bought them out after he won a patent-infringement lawsuit he had filed against them. In 1922, the firm changed its name to Athol Machine & Foundry Co.
Athol Machine Co. was better known for their machinists' hand tools, such as squares and calipers. Since this web site's focus does not include hand tools, we cannot provide any information on most of Athol's products. They are listed here because they made vises and a grinder.
Athol Machine Co. manufactured the Simpson line of vises, which it acquired from Bailey Wringing Machine Co. before 1896.
