USS Ranger (1876)
USS ''Ranger'', later USS ''Rockport'' and USS ''Nantucket'' (PG-23/IX-18), was a gunboat of the United States Navy. A screw steamer with full-rig auxiliary sail, ''Ranger'' was destined for a very long 65-year career, serving first as a U.S. Navy gunboat from 1876 to 1920, and later as a training ship with the Massachusetts Maritime Academy from 1909 to 1941. The ship was finally scrapped in 1958, but her engine, which is the only one of its type known to be still in existence, was preserved and is on display at the American Merchant Marine Museum of Kings Point, New York. Design and construction ''Ranger'' was built by Harlan and Hollingsworth of Wilmington, Delaware. She was laid down in 1873, and launched in 1876. ''Ranger''s engine was designed by the Bureau of Steam Engineering and built by John Roach & Sons of Chester, Pennsylvania. The engine is of the compound back-acting type, with cylinders of 28½ and 42½ inches respectively, and a 42-inch stroke. T ...

League Island Naval Shipyard
The Philadelphia Naval Shipyard was an important naval shipyard of the United States for almost two centuries. Philadelphia's original navy yard, begun in 1776 on Front Street and Federal Street in what is now the Pennsport section of the city, was the first naval shipyard of the United States. It was replaced by a new, much larger yard developed around facilities begun in 1871 on League Island, at the confluence of the Delaware and Schuylkill rivers. The Navy Yard expansion stimulated the development over time of residential and businesses in South Philadelphia, where many shipyard workers lived. During World War II, some 40,000 workers operated on shifts around the clock to produce and repair ships at the yard for the war effort. The United States Navy ended most of its activities there in the 1990s, closing its base after recommendations by the Base Realignment and Closure commission. In 2000, the Philadelphia Industrial Development Corporation, on behalf of the city of Ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pounds Per Square Inch
The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 Pa. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pounds per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to something other than ambient atmospheric pressure, then the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scotch Boiler
A "Scotch" marine boiler (or simply Scotch boiler) is a design of steam boiler best known for its use on ships. The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes. Gases and smoke from the furnace pass to the back of the boiler, then return through the small tubes and up and out of the chimney. The ends of these multiple tubes are capped by a smokebox, outside the boiler shell. The Scotch boiler is a fire-tube boiler, in that hot flue gases pass through tubes set within a tank of water. As such, it is a descendant of the earlier Lancashire boiler, and like the Lancashire it uses multiple separate furnaces to give greater heating area for a given furnace capacity. It differs from the Lancashire in two respects: many small-diameter tubes (typically diameter each) are used to increase the ratio of heating area to cross-section. Secondly, the overa ...

Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids such as arsenic or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as ultimate tensile strength, strength, ductility, or machinability. The three-age system, archaeological period in which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia and India is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age starting from about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in mod ...

Marine Steam Engine
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam turbines and marine diesel engines. History The first commercially successful steam engine was developed by Thomas Newcomen in 1712. The steam engine improvements brought forth by James Watt in the later half of the 18th century greatly improved steam engine efficiency and allowed more compact engine arrangements. Successful adaptation of the steam engine to marine applications in England would have to wait until almost a century after Newcomen, when Scottish engineer William Symington built the world's "first practical steamboat", the '' Charlotte Dundas'', in 1802.

Chester, Pennsylvania
Chester is a city in Delaware County, Pennsylvania, United States. Located within the Philadelphia Metropolitan Area, it is the only city in Delaware County and had a population of 32,605 as of the 2020 census. Incorporated in 1682, Chester is the oldest city in Pennsylvania and is located on the western bank of the Delaware River between the cities of Philadelphia and Wilmington, Delaware. It was the location of William Penn's first arrival in the Province of Pennsylvania and the county seat for Chester County from 1682 to 1788 and Delaware County from 1789 to 1851. Chester evolved over the centuries from a small town with wooden shipbuilding and textile factories into an industrial powerhouse producing steel ships for two World Wars and a myriad of consumer goods. Since the mid-twentieth century, it has lost its manufacturing base and over half of its residents and devolved into a post-industrial city struggling with pollution, poverty, and crime.

Bureau Of Steam Engineering
The Bureau of Steam Engineering was a bureau of the United States Navy, created by the act of 5 July 1862, receiving some of the duties of the former Bureau of Construction, Equipment and Repair. It became, by the Naval Appropriation Act of 4 June 1920, the Bureau of Engineering (BuEng). In 1940 it combined with the Bureau of Construction and Repair (BuC&R) and became the Bureau of Ships (BuShips). Historical background "Engineering, both in operating the shipboard machinery and in the design and construction of ships, became critically important with the outbreak of the Civil War. The Navy had to blockade a ‘coastline stretching over 3,000 miles from the Potomac to the Mexican border. It had to support the Army on the rivers; it had to search out and destroy Confederate raiders. For all these purposes, the steam engine and the engineer were indispensable. On the day of battle, steam engines drove the ''Monitor'' and the ''Merrimack'', the ''Kearsarge'' and the ''Alabama'', as ...

Harlan And Hollingsworth
Harlan & Hollingsworth was a Wilmington, Delaware, firm that constructed ships and railroad cars during the 19th century and into the 20th century. Founding Mahlon Betts, a carpenter, arrived in Wilmington in 1812. After helping construct many prominent buildings in the city, Betts branched out into foundry work in 1821. In 1836, Betts partnered with Samuel Pusey (a machinist) and began manufacturing railcars at a plant on West and Water Streets in Wilmington. The next year, cabinetmaker Samuel Harlan joined the firm, then known as Betts, Pusey & Harlan. By 1839, the company claimed to have manufactured 39 passenger and 28 freight cars over the previous two years. The next year, they hired Jacob F. Sharp, a former house carpenter, to build railroad cars. He would rise to become foreman at the plant, and eventually co-founded the rival firm of Jackson and Sharp. In 1841, Elijah Hollingsworth, brother-in-law of Harlan, bought out Pusey, and the firm became known as Betts, Harlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
