Cummings Machine Works was a Boston, Massachusetts based business. It was founded by Henry Havelock Cummings in 1881, when Cummings was 23 years old. [1] The company was awarded a United States Defense Department contract to manufacture fixtures in March 1941. The contract amounted to $17,893. [2] The company was among the firms which contributed to the building of the Boston Opera House, completed in 1909, supplying steelworks used in the construction of the stage. [3]
Cummings Machine Works has been credited with the development of the sally saw. A patent filed in 1945, and assigned to the company, describes a saw with a circular blade. The blade could be rotated between horizontal and vertical, thus allowing a tree to be felled, limbed, and bucked with one saw. [4] Other inventions included a hydraulic hospital bed, automatic doughnut machine, teardrop vehicle and Hookups.[ citation needed]
Last owners were Robert M. Mustard Sr., president, and Lewis W. Mustard, treasurer. Last known address was 10 Melcher Street in Boston. Went out of business in 1958.
