Cummings Machine Works

Cummings Machine Works

Cummings Machine Works was a Boston, Massachusetts based business which was awarded a United States Defense Department contract to manufacture fixtures in March 1941. The contact amounted to $17,893.[1] The company was among the firms which contributed to the building of the Boston Opera House. It was completed in 1909.[2]

Cummings Machine Works has been credited with the development of the Sally Saw. Employees of the company conceived of a method whereby a logger could cut down a tree with a horizontal cut, then shut down the saw. Next he would turn the blade a quarter turn (90 degrees). He could restart the saw to make the necessary vertical cuts. The process was cumbersome yet a lot easier and quicker than an axe or a two-man crosscut saw.[3]
