19th-century American Inventors
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northampton, Pennsylvania
Northampton is a borough in Northampton County, Pennsylvania. Its population was 10,395 as of the 2020 census. Northampton is located north of Allentown, northwest of Philadelphia, and west of New York City. The borough is part of the Lehigh Valley metropolitan area, which had a population of 861,899 and was thus the 68th most populous metropolitan area in the U.S. as of the 2020 census. History Northampton and surrounding areas of the Lehigh Valley are rich in limestone, which is commonly used in the production of cement. The Atlas Portland Cement Company, based here from 1895 to 1982, was the world's largest cement company at one time, and one of dozens in the area. It produced some 8 million barrels of cement for construction of the Panama Canal, most of what was used on the project. Atlas was bought by another company in 1980 and ceased operation here in 1982; its last smokestack here was demolished in 1993. Today technology and automation mean that the cement industry can ...

Lehigh River
The Lehigh River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 1, 2011 tributary of the Delaware River in eastern Pennsylvania. The river flows in a generally southward pattern from The Poconos in Northeastern Pennsylvania through Allentown and much of the Lehigh Valley before enjoining the Delaware River in Easton. Part of the Lehigh River and a number of its tributaries are designated Pennsylvania Scenic Rivers by the state's Department of Conservation and Natural Resources. The river's name "Lehigh" is an anglicisation of the Lenape name for the river, ''Lechewuekink'', which means "where there are forks". Both Lehigh County and Lehigh Valley are named for the river. According to an environmental report from a Pennsylvania nonprofit research center, the Lehigh River watershed is ranked second nationally in the volume of toxic substances released into it in 2020.

Merrimack River
The Merrimack River (or Merrimac River, an occasional earlier spelling) is a river in the northeastern United States. It rises at the confluence of the Pemigewasset and Winnipesaukee rivers in Franklin, New Hampshire, flows southward into Massachusetts, and then flows northeast until it empties into the Gulf of Maine at Newburyport. From Pawtucket Falls in Lowell, Massachusetts, onward, the Massachusetts–New Hampshire border is roughly calculated as the line three miles north of the river. The Merrimack is an important regional focus in both New Hampshire and Massachusetts. The central-southern part of New Hampshire and most of northeast Massachusetts is known as the Merrimack Valley. Several U.S. naval ships have been named and USS ''Merrimac'' in honor of this river. The river is perhaps best known for the early American literary classic ''A Week on the Concord and Merrimack Rivers'' by Henry David Thoreau.

Newburyport, Massachusetts
Newburyport is a coastal city in Essex County, Massachusetts, United States, northeast of Boston. The population was 18,289 at the 2020 census. A historic seaport with vibrant tourism industry, Newburyport includes part of Plum Island. The mooring, winter storage, and maintenance of recreational boats, motor and sail, still contribute a large part of the city's income. A Coast Guard station oversees boating activity, especially in the sometimes dangerous tidal currents of the Merrimack River.

Chain Bridge (Massachusetts)
The Chain Bridge in Newburyport, Massachusetts, is a "look-alike" replica built in 1910 to replace the "first suspension bridge" constructed in the United States in 1810. Since the current structure is one of a series of bridges at this location since 1793, it is "the oldest continually occupied, long span, bridge crossing" in the US. It has also been called the Essex-Merrimac Bridge or Newburyport Chain Bridge. It is a 225-foot chain bridge, a single-span suspension bridge, which crosses the right branch of the Merrimack River as it flows around Deer Island. The boundary between the cities of Newburyport and Amesbury, Massachusetts, runs through Deer Island, so Chain Bridge connects the two communities. Crossing from the island to the left bank of the Merrimack requires traversing the Derek S. Hines Memorial Bridge, formerly the Essex-Merrimack Drawbridge, which was reconstructed and reopened in August 2012. As the Chain Bridge is better known because of its structure, it is some ...

Chain Bridge At Falls Of Schuylkill
Chain Bridge at Falls of Schuylkill was an 1808 iron-chain suspension bridge built across the Schuylkill River, north of Philadelphia, Pennsylvania. Designed by inventor James Finley, it became the model for his later chain suspension bridges. It collapsed in 1816 under a heavy load of snow. History The Chain Bridge had two spans: an eastern one of 200 feet (60.96 m), and a western one of about 100 feet (30.48 m). The bridge's chain cables were carried over paired A-frame wooden towers on its east and west abutments, and a third pair of towers atop a stone pier built in the river. Its chains were made of 1.5-inch-square (3.8 cm) iron bar wrought into links of between 8 and 12 feet (2.44 and 3.66 m) in length. These were used for both the cables and the vertical suspenders. The suspenders were attached to 10-by-5-inch (25.4 cm x 12.7 cm) wooden joists spaced 10 feet (3 m) apart, and covered by a 2.5-inch-thick (6.4 cm) wooden deck that was 18 feet (5.5 m) wide ...

Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
