History of the Athol Machine Company.

Athol Machine Company (1868 – ?)

Laroy Starrett, one of America’s tool pioneers and inventor of the combination square was the founder, along with other associates, of the Athol Machine Company in 1868. During the time with the company Starrett developed a line of vises a meat chopper and other mechanics tools. He left the company due to patent disputes in 1875. Subsequently, Laroy sued the Athol Manufacturing Co. and won, this left him with enough capital to buy the company in 1905. Records from the Secretary of the Commonwealth Massachusetts Division of Corporations prove that Athol Machine Co. changed its name to Athol Machine and Foundry in December 1920. Therefore Athol vises bearing the name “Athol Machine Co” are pre 1921 and those bearing the name “Athol M&FCo” are post 1920. The Starret company is still in operattion and basically any Athol vise manufactured after 1905 is a Starrett vise whether it bears the Starrett brand or not. Even though Athol vises are no longer manufactured there is no record of the company’s closing. Athol Machine Company’s main building still stands and can be observed in Google Maps Satellite View, please see pictures below.
