This machine is an unusual triple-expansion, three-crank rocker engine, which in its day was a high-capacity unit providing outstanding performance for the Boston Water Works Corporation. Designed by Erasmus Darwin Leavitt, Jr. (1836-1916), Engine No. 3 was installed in 1894 to a high-service pumping facility on the south side of the Chestnut Hill Reservoir in Brighton.

The La Esperanza sugar mill steam engine is one of the few remaining American links to the pioneer beam engines of the English inventors Thomas Newcomen (1712) and James Watt (1769). The engine was built in 1861 in Cold Spring, New York, by the West Point Foundry. The general arrangement and details, including the Gothic embellishment, are typical of machinery of the period. The straight-line motion of the piston rod is accommodated to the arc of the moving beam end by a parallel motion. Watt regarded this ingenious linkage as the invention of which he was most proud.

This is one of the earliest US foundry-machine shops remaining in operation and one of the few water powered. It was founded by Samuel N. Knight (1838-1913) to manufacture machinery for the gold mines of the Mother Lode region. Knight was one of several inventors experimenting with impulse turbines to exploit the area's abundant high-head water power for driving hoists, ore stamps, and other mining machinery.

This Kaplan turbine is one of the first three machines to be put into service in the United States. Named for its Austrian inventor, Viktor Kaplan (1876-1934), the turbine was an outstanding innovation, operating with a high, nearly constant efficiency over a wide load range. The machine was built by S. Morgan Smith Company of York, Pennsylvania.

This is one of several, similar inclines built in western Pennsylvania during the late 19th century. It was designed by Samuel Diescher (1839-1915) after the great flood of 1889, to provide an efficient means of transportation between Westmont and the Conemaugh Valley. (See also the Monogahela and Duquesne Inclines in Pittsburgh.)

The oscillating steam engine, built by John Penn & Sons, is located aboard the famed paddle steamer Diesbar. Diesbar is the second oldest of a fleet of nine paddle steamers in Dresden. What makes the Diesbar unique is its coal fueled engine and single deck design. The John Penn and Sons engine that runs the steamer is the oldest operational marine steam engine in the world. It has been in operation for over 165 years.

The Jake Brake permits large trucks to descend long, steep grades at a controlled speed. It was the first practical mechanism for altering on demand the valve timing on a truck diesel engine, thereby converting the engine to a power absorbing machine. The modified engine can continue to power the truck in normal operation, allowing service brakes to remain cool for emergency situations. Invented by Clessie Lyle Cummins (1886-1968), this device (produced by the Jacobs manufacturing company since 1961) has contributed significantly to highway safety.

This facility was typical of others in the country that made small spherical lead shot for the fowling pieces of frontier settlers. Smelted lead from the nearby Austinville mines was melted at the top of the tower and poured through a sizing sieve to produce small droplets. Surface tension caused the molted lead to assume a spherical shape that solidified during its 150-foot fall. The shot was then collected in a water-filled kettle at the bottom of the shaft. The "drop process" was patented in England in 1769 by William Watts, a craftsman of Bristol, England.
