Revere Copper And Brass
The Revere Copper Company is a copper rolling mill in the United States. It operated North America's first copper rolling mill. It was started by Paul Revere in 1801 in Canton, Massachusetts, and developed a commercially viable process for manufacturing copper sheets. History Copper rolling process Copper rolling is the process of converting large blocks of copper into thin sheets by rolling them gradually down to size. These sheets of copper were used in the 18th and 19th centuries mainly to plate the bottoms of ships. This process of plating ship bottoms, referred to as “sheathing” or “coppering”, helped increase the speed and lifespan of ships. Copper was desired for this process because it reacts with seawater to create an oxide coating that prevents the build-up of barnacles, weeds, and other detritus, in addition to physically stopping shipworm, shipworms from burrowing into and degrading the wood.

Canton, Massachusetts
Canton is a town in Norfolk County, Massachusetts, Norfolk County, Massachusetts, United States. The population was 24,370 at the 2020 census. Canton is part of Greater Boston, about 15 miles (24 kilometers) southwest of downtown Boston. History The area that would become Canton was inhabited for tens of thousands of years prior to European colonization of the Americas, European colonization. The Paleo-Indians, Paleo-Indian site Wamsutta, Radiocarbon dating, radiocarbon dated to 12,140 years before present, is located within the bounds of modern day Canton at Signal Hill (Canton, Massachusetts), Signal Hill. At the time of the Puritan migration to New England (1620–1640), Puritan migration to New England in the early 1600s, Canton was seasonally inhabited by the Neponset band of Massachusett under the leadership of sachem Chickatawbut.

Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals; that is, the way in which science is applied to the production of metals, and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mi ...

Boston And Providence Railroad
The Boston and Providence Railroad was a railroad company in the states of Massachusetts and Rhode Island which connected its namesake cities. It opened in two sections in 1834 and 1835 - one of the Rail transport in the United States, first rail lines in the United States - with a more direct route into Providence built in 1847. Branches were built to Dedham in 1834, Stoughton in 1845, and North Attleboro in 1871. It was acquired by the Old Colony Railroad in 1888, which in turn was leased by the New Haven Railroad in 1893. The line became the New Haven's primary mainline to Boston; it was realigned in Boston in 1899 during the construction of South Station, and in Pawtucket and Central Falls in 1916 for grade crossing elimination. The line became part of the Penn Central system in 1969; the section in Massachusetts was purchased by the state in 1973, while Amtrak acquired the Rhode Island section in 1976. The line was electrified in 2000; it is now the far northern leg of Amtrak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steamboats
A steamboat is a boat that is marine propulsion, propelled primarily by marine steam engine, steam power, typically driving propellers or Paddle steamer, paddlewheels. Steamboats sometimes use the ship prefix, prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'); however, these designations are most often used for steamships. The term ''steamboat'' is used to refer to smaller, insular, steam-powered boats working on lakes and rivers, particularly riverboats. As using steam became more reliable, steam power became applied to larger, ocean-going vessels. Background Limitations of the Newcomen steam engine Early steamboat designs used Newcomen atmospheric engine, Newcomen steam engines. These engines were large, heavy, and produced little power, which resulted in an unfavorable power-to-weight ratio. The Newcomen engine also produced a reciprocating or rocking motion because it was designed for pumping. The piston stroke was caused by a water jet i ...

Robert Fulton
Robert Fulton (November 14, 1765 – February 24, 1815) was an American engineer and inventor who is widely credited with developing the world's first commercially successful steamboat, the (also known as ''Clermont''). In 1807, that steamboat traveled on the Hudson River with passengers from New York City to Albany and back again, a round trip of , in 62 hours. The success of his steamboat changed river traffic and trade on major American rivers. In 1800, Fulton had been commissioned by Napoleon Bonaparte, leader of France, to attempt to design a submarine; he produced , the first practical submarine in history. Fulton is also credited with inventing some of the world's earliest naval torpedoes for use by the Royal Navy.Best, Nicholas (2005). ''Trafalgar: The Untold Story of the Greatest Sea Battle in History''. London: Phoenix. . Fulton became interested in steam engines and the idea of steamboats in 1777 when he was around age 12 and visited state delegate William Henry o ...

Annealing (metallurgy)
In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate amount of time and then cooling. In annealing, atoms migrate in the crystal lattice and the number of dislocations decreases, leading to a change in ductility and hardness. As the material cools it recrystallizes. For many alloys, including carbon steel, the crystal grain size and phase composition, which ultimately determine the material properties, are dependent on the heating rate and cooling rate. Hot working or cold working after the annealing process alters the metal structure, so further heat treatments may be used to achieve the properties required. With knowledge of the composition and phase diagram, heat treatment can be used to ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Rolling
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes... Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock), bar stock, and rails. Most steel mills ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joshua Humphreys
Joshua Humphreys (June 17, 1751 – January 12, 1838) was an American ship builder and naval architect. He was the constructor of the original six frigates of the United States Navy and is known as the "Father of the American Navy". Humphreys was born in Ardmore, Haverford Township, Pennsylvania, and died in the same place. He was the son of Joshua Humphreys and Sarah Williams, grandson of Daniel Humphreys and Hannah Wynne (daughter of Dr. Thomas Wynne). He was a nephew of Charles Humphreys. His residence, Pont Reading, is still a private residence. Career As a youth, Humphreys was apprenticed to a shipbuilder in Philadelphia, Pennsylvania. During his apprenticeship, his instructor died and he was placed in charge of the establishment. During the American Revolutionary War he was active as a designer, and played a major part in planning the 32-gun frigate before the British Army occupation of Philadelphia halted that effort. In postwar Philadelphia, Humphreys became a shi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Department Of The Navy
The United States Department of the Navy (DoN) is one of the three military departments within the Department of Defense of the United States of America. It was established by an Act of Congress on 30 April 1798, at the urging of Secretary of War James McHenry, to provide a government organizational structure to the United States Navy (USN);Bernard C. Steiner and James McHenry, The life and correspondence of James McHenry' (Cleveland: Burrows Brothers Co., 1907). since 1834, it has exercised jurisdiction over the U.S. Marine Corps (USMC) and, during wartime, the U.S. Coast Guard (USCG), though each remains an independent service branch. It is led by the Secretary of the Navy (SECNAV), a statutory civilian officer. The Department of the Navy was an executive department, whose secretary served on the president's cabinet, until 1949, when amendments to the National Security Act of 1947 established the Department of Defense as a unified department for all military service ...

Ironworks
An ironworks or iron works is an industrial plant where iron is smelted and where heavy iron and steel products are made. The term is both singular and plural, i.e. the singular of ''ironworks'' is ''ironworks''. Ironworks succeeded bloomeries when blast furnaces replaced former methods. An integrated ironworks in the 19th century usually included one or more blast furnaces and a number of puddling furnaces or a foundry with or without other kinds of ironworks. After the invention of the Bessemer process, converters became widespread, and the appellation steelworks replaced ironworks. The processes carried at ironworks are usually described as ferrous metallurgy, but the term siderurgy is also occasionally used. This is derived from the Greek words ''sideros'' - iron and ''ergon'' or ''ergos'' - work. This is an unusual term in English, and it is best regarded as an anglicisation of a term used in French, Spanish, and other Romance languages. Historically, it is common ...
