The Boyden turbines installed in Mill No. 3 in 1873 are two of the oldest surviving mill water turbines that remain intact in their original installation. Their design is of the Boyden outward flow type, the first turbine to be manufactured in quantity in the United States and a standard in the textile industry from 1844 to about 1880. They were the largest of the 32 Boyden turbines built by the Holyoke [Massachusetts] Company between 1873 and 1876. The American Society of Mechanical Engineers designated the turbines as National Historic Mechanical Engineering Landmarks in 1975 as probably the largest and nearly the most powerful water turbines ever built in the United States to supply direct mechanical power to a manufacturing plant.
