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 ironworks exemplified the adaptability required for industrial survival in a dynamic technical environment. It was a major western producer of mechanical equipment used in mining (especially large hydraulic machines), ship propulsion, irrigation, power generation, optical telescope mounts, and nuclear research.
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.
Although not the first four-wheel-drive vehicle or the first designed for rough, multipurpose field use, the Jeep MB was built as an unusual combination of these and other features of modern vehicle design in the World War II era.
This collection includes many examples of advances in mechanical refrigeration for residential and commercial applications, dating from about 1890 to 1960. Such devices dramatically improved food storage safety and convenience and set high standards for mechanical reliability. The RRM collection…Read More
Installed alongside an Epping Carpenter pump that was later scrapped, this water pump was built by Allis-Chalmers, which for many years had Edwin Reynolds as its chief engineer. Driven by a Corliss steam engine, these large city water pumps were installed in Jacksonville's water supply…Read More
Beginning with the blacksmith shop of German immigrant Meinrad Rumely (1823-1904), this successive family of firms invented and produced a line of agricultural equipment that played a vital role in the evolution of farming based on the muscle of humans and animals to one based on the power of…Read More
This silver mine preserves two features of bygone practice. One is the reversible waterwheel of the ore-hoist, which originally was installed in 1565 and currently dates back to 1824. The present wheel is 9 meters in diameter and reaches a depth of 700 meters.
Second, the man engine of…Read More
The first commercial central electric-generating station in the United States to use nuclear energy was the Shippingport Atomic Power Station of the Department of Energy and the Duquesne Light Company. In a dramatic high-tech display, ground was broken in 1954 during dedication ceremonies by…Read More
Siegfried Marcus (1833-1898), a remarkable engineer and manufacturer, lived most of his life and died in Vienna, leaving his most important legacy — an experimental automobile resembling today's modern car and the oldest extant automobile known worldwide. Marcus' second car, built circa 1875 (a…Read More
