Rubber Tractor Tires
Society: ASABE Main Category: Agricultural & Biological Sub Category: Vehicles Era: 1920-1929 DateCreated: 1926 Orange County Historical Society Orange State: VA Zip: 22960 Country: USA Website: https://www.asabe.org/awards-landmarks/asabe-historic-landmarks/rubber-tractor-tires-34.aspx Creator: Pounds, Hoyle, Allis-Chalmers Company, Roorda, Hessel

Early tractors were massive and expensive. Their steel lug wheels gave poor traction and a rough ride. Lugs were prohibited on many roads. 1926 Hoyle Pounds modified a Fordson tractor with zero pressure truck tires on special rims to improve performance on sandy soils in Winter Garden, FL.

A successful business resulted. In 1929 Hessel Roorda equipped Farmall tractors with low pressure rubber tires to pick corn in muddy fields near Rock Valley, IA. Farmers found they performed well in all conditions.

The Langley Memorial Aeronautical Laboratory, now the core of the Langley Research Center, was a unique facility that served as the nexus of aerodynamic research in the U.S. from its beginning in 1917 to its transformation into NASA’s Langley Research Center in 1958. It achieved world renown for its variety of specialized research tools and its staff’s emphasis on practical solutions to the problems of flight.

Udvar-Hazy Center Chantilly State: VA Zip: 20151 Country: USA Website: http://www.asme.org/about-asme/history/landmarks/topics-a-l/air-and-space-transportation/-178-boeing-367-80-%281954%29-, http://files.asme.org/asmeorg/Communities/History/Landmarks/5506.pdf Creator: Boeing
The 367-80 is the prototype for most jet transports. Its success was due largely to its mechanical systems, including turbine engines with thrust reversers and noise suppressors, redundant hydraulic control systems, and an improved cabin-pressurization system. Honeycomb flap panels were introduced, along with a strong, lightweight structural design that controlled fatigue cracking. These led to several innovations in aircraft tooling and manufacturing techniques. The Dash-80 was the first commercial airliner economical enough to take the US airline industry off subsidy.

McCormick was born on the 620-acre farm known historically as “Walnut Grove Farm” in 1809.  He built the first practical grain reaper, which was successfully demonstrated in a field of oats owned by John Steele in nearby Steeles Tavern in 1831.

Designed to connect the Shenandoah National Park in Virginia and the Great Smokey Mountains National Park in North Carolina, the Blue Ridge Parkway was planned to provide pleasant motoring and to conserve and interpret the unique natural and cultural resources of the Southern Highlands. It was conceived also as a public works project to relieve unemployment in the Appalachian region during the Great Depression.

Potowmack Canal and Locks

These canals and locks are a part of the first extensive system of canal and river navigation works undertaken in the United States. The idea for the canal was proposed by George Washington, when, as an engineer, surveyor and military emissary for Virginia, he saw the need for a trade route west beyond the Allegheny Mountains. In order to do create this route, it was necessary to try to tame the Potomac River which was a wild, unruly stream which only the hardiest of rivermen ever attempted.

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.

Baldwin's dry dock in Virginia has been designated a National Historical Landmark and is still in use at the Norfolk Naval Shipyard. The Charlestown dry dock and original pump house, while no longer used, are on display as part of the Boston National Historical Park. Although the need for dry-docking facilities to speed the cleaning and repair of ships in America's naval fleet was apparent as early as 1789, it was the War of 1812, and the burning of Washington, D.C., that finally convinced Congress of the importance of a coastal defense system based on a strong navy.

The Dismal Swamp Canal was created as a 22-mile waterway, extending from Deep Creek, Virginia to South Mills, North Carolina. The canal enabled North Carolina producers of building and agricultural products to deliver goods to the Port of Norfolk where they were transferred to ocean-going vessels.
