This is the earliest known survivor of an integrated cotton ginning system widely used to process cotton from wagon to bale in a continuous operation. The gin machinery was designed and built in 1914 by the Lummus Cotton Gin Company. It can process seven bales per hour. Five gin stands, stick machine, burr machine, separators, cleaners, press pump, and pneumatic conveying fans are driven by a 125-hp Bessemer oil engine. This gin ran commercially until 1974 and was restored to operating condition in 1993.

During the post-Civil War era, efforts to cultivate the land for higher crop yields resulted in the digging of thousands of miles of ditches to improve land drainage. Accurately graded ditches were needed for open drainage, pipeline trenches and placement of underground agricultural drainage tile. Teams of skilled workers laid out the direction and gradient of a ditch and dug it out with pick and shovel. The Black Swamp area, where Lake Erie drains into northwest Ohio and southeast Michigan, was the center of much of the U.S. ditching activity.

This collection recognizes the inventive talents of John Moses Browning (1855-1926), a prolific and significant designer of sporting and military firearms, whose designs were known for simplicity, accuracy, and reliability. He held more than 128 patents covering 80 distinct firearms produced by Winchester, Remington, Colt, Fabrique Nationale, Savage, and General Motors (during wartime), among others.

Founded by Eleuthère Irénéé du Pont (1771-1834), the Brandywine River Mills became the largest maker of explosive black powder in the United States. That success resulted directly from the firm's pioneering use of gunpowder processing machinery driven by water wheels and water turbines.

These two water turbines were probably the largest and nearly the most powerful ever built in the United States, supplying direct mechanical power to a manufacturing plant. Their installation between 1871 and 1873 makes them among the oldest surviving water turbines.
A dam at Cohoes diverted water to mills and factories along a power canal system. The vertical-shaft turbines at the mill were said to run at 800 horsepower (600 kilowatt) under a head of 20 feet and were connected to an overhead shaft by bevel gearing.

This is the first commercial, human-blood heat exchanger. Developed in 1957, it permitted a patient's body temperature to be safely and rapidly lowered during open heart surgery to any desired and precisely controlled hypothermic level, then during the conclusion of the operation rapidly rewarmed to normal. Prior to this, hypothermic surgery required hours of preoperative, hard-to-control, external emersion cooling and postoperative rewarming.
Its design was a cooperative development between researchers at the Duke University Medical Center led by Dr. Ivan W.

The ballpoint pen invented by Ladislao Jose Biro was originally patented in Hungary in 1938. The principle of the ballpoint pen was originally patented by John Loud in 1888 for a product to mark leather and in 1916 by Van Vechten Riesberg, but neither of these products were exploited commercially.
As a journalist, Biro was inspired by the concept of quick-drying ink in a print shop.

When built in 1962, this shovel was the second largest in the world. It was used for the removal of overburden in the surface mining of thin coal seams. In its lifetime, it recovered nine million tons of bituminous coal from depths of 20 to 50 feet for local electric power generation. Standing 160-feet high, weighing 5,500 tons, and moving at speeds up to two-tenths of a mile per hour, the machine stripped about a square mile each year.

This unit, retired from the Belle Isle Station of the Oklahoma Gas & Electric Company, was the first gas turbine to be used for electric utility power generation in the United States. It represents the transformation of the early aircraft gas turbine, in which the engines seldom ran more than ten hours at a stretch, into a long-life prime mover. This redesign was based upon creep-rupture tests of S-816 cobalt-base alloys for turbine buckets. The low-cost trouble-free service led to wide-scale adoption of the gas turbine, over 45 million kilowatt capacity (over 9 percent of U.S.

Built by the Bay City Dredge Works of Bay City, Michigan, this dredge was used to construct a portion of US 41 called the Tamiami Trail, which connected Tampa with Miami through the Everglades and Big Cypress Swamp. The last remaining display of walking dredges (of some 145 walking machines), it has a unique propulsion design enabling the dredge to cope with drainage problems in a wetlands environment.
