John Roach And Sons
John Roach & Sons was a major 19th-century American shipbuilding and manufacturing firm founded in 1864 by Irish-American immigrant John Roach. Between 1871 and 1885, the company was the largest shipbuilding firm in the United States, building more iron ships than its next two major competitors combined. It was also by far the largest contractor to the U.S. Navy during this period, and at its peak is said to have been the nation's largest employer behind the railroads. Overview The company, originally named John Roach & Son, was established in 1864 as the operating and marketing firm for Roach's Etna Iron Works in New York, and gave Roach's eldest son, William Henry Roach, a stake in the business. Roach's other sons later joined the partnership. As Roach's business empire expanded, a number of new companies were added as subsidiaries, the most important of which were the Delaware River Iron Ship Building and Engine Works in Chester, Pennsylvania, which was the main shipbuil ...

John Roach (shipbuilder)
John Roach (December 25, 1815 – January 10, 1887) was an American industrialist who rose from humble origins as an Irish immigrant laborer to found the largest and most productive shipbuilding empire in the postbellum United States, John Roach & Sons. Roach emigrated to the United States at the age of sixteen in 1832, eventually finding employment at the Howell Works of James P. Allaire in New Jersey, where he learned the ironmolder's trade. Following an abortive attempt at farming in Illinois in 1839, Roach returned to Allaire's employment at the Allaire Iron Works in New York City, where he learned how to build marine steam engines. In 1852, after 20 years in the employment of Allaire, Roach and three partners purchased a small New York ironworks which had fallen into receivership, the Etna Iron Works. Roach soon became sole proprietor, and during the American Civil War transformed the Etna Works into a major manufacturer of marine engines. He continued to prosper after ...

Rolling Mill
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] |
Dynamo
file:DynamoElectricMachinesEndViewPartlySection USP284110.png, "Dynamo Electric Machine" (end view, partly section, ) A dynamo is an electrical generator that creates direct current using a commutator (electric), commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later Electric power conversion, electric-power conversion devices were based, including the electric motor, the Alternating current, alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale Electricity generation, power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a commutator (electric), mechanical commutator. Also, converting alternating to direct current using rectifiers (such as vacuum tubes or more recently via Solid state (electronics), solid state technology) is effective and usually economical.

Oregon Railroad And Navigation Company
The Oregon Railroad and Navigation Company (OR&N) was a railroad that operated a rail network of running east from Portland, Oregon, United States, to northeastern Oregon, northeastern Washington, and northern Idaho. It operated from 1896 as a consolidation of several smaller railroads. OR&N was initially operated as an independent carrier, but Union Pacific (UP) purchased a majority stake in the line in 1898. It became a subsidiary of UP titled the Oregon–Washington Railroad and Navigation Company in 1910. In 1936, Union Pacific formally absorbed the system, which became UP's gateway to the Pacific Northwest. Predecessors The OR&N was made up of several railroads: *Columbia Southern Railway from Biggs to Shaniko, Oregon. *Oregon ''Railway'' and Navigation Company traces its roots back as far as 1860. It was incorporated in 1879 in Portland, Oregon and operated between Portland and eastern Washington and Oregon until 1896, when it was reorganized into the Oregon ''Railroad'' ...

SS Columbia (1880)
SS ''Columbia'' (1880–1907) was a cargo and passenger steamship that was owned by the Oregon Railway and Navigation Company and later the San Francisco and Portland Steamship Company. ''Columbia'' was constructed in 1880 by the John Roach & Sons shipyard in Chester, Pennsylvania for the Oregon Railway and Navigation Company. ''Columbia'' was the first ship to carry a dynamo powering electric lights instead of oil lamps and the first commercial use of electric light bulbs outside of Thomas Edison's Menlo Park, New Jersey laboratory. Due to this, a detailed article and composite illustration of ''Columbia'' was featured in the May 1880 issue of ''Scientific American'' magazine. ''Columbia'' was lost on 21 July 1907 after a collision with the lumber schooner '' San Pedro'' off Shelter Cove, California, with the loss of 88 lives.Dalton, AnthonA long, dangerous coastline : shipwreck tales from Alaska to CaliforniaHeritage House Publishing Company, 1 Feb 2011 - 128 pages History ...

Rail Transport In The United States
Rail transportation in the United States consists primarily of freight shipments, with a well integrated network of standard gauge private freight railroads extending into Canada and Mexico. Passenger service is mainly mass transit and commuter rail in major cities. Intercity passenger service, once a large and vital part of the nation's passenger transportation network, plays a limited role as compared to transportation patterns in many other countries. The United States has the largest rail transport network size of any country in the world. The nation's earliest railroads were built in the 1820s and 1830s, primarily in New England and the Mid-Atlantic region. The Baltimore and Ohio Railroad, chartered in 1827, was the nation's first common carrier railroad. By 1850, an extensive railroad network had begun to take shape in the rapidly industrializing Northeastern United States and the Midwest, while relatively fewer railroads were constructed in the primarily agricultural S ...

Payroll
A payroll is the list of employees of some company that is entitled to receive payments as well as other work benefits and the amounts that each should receive. Along with the amounts that each employee should receive for time worked or tasks performed, payroll can also refer to a company's records of payments that were previously made to employees, including salaries and wages, bonuses, and withheld taxes, or the company's department that deals with compensation. A company may handle all aspects of the payroll process in-house or can outsource aspects to a payroll processing company. Payroll in the U.S. is subject to federal, state and local regulations including employee exemptions, record keeping, and tax requirements. Frequency Companies typically process payroll at regular intervals. This interval varies from company to company and may differ within the company for different types of employee. According to research conducted in February 2022 by the U.S. Department of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ingot
An ingot is a piece of relatively pure material, usually metal, that is cast into a shape suitable for further processing. In steelmaking, it is the first step among semi-finished casting products. Ingots usually require a second procedure of shaping, such as cold/hot working, cutting, or milling to produce a useful final product. Non-metallic and semiconductor materials prepared in bulk form may also be referred to as ingots, particularly when cast by mold based methods. Precious metal ingots can be used as currency (with or without being processed into other shapes), or as a currency reserve, as with gold bars. Types Ingots are generally made of metal, either pure or alloy, heated past its melting point and cast into a bar or block using a mold chill method. A special case are polycrystalline or single crystal ingots made by pulling from a molten melt. Single crystal Single crystal ingots (called boules) of materials are grown (crystal growth) using methods such as the Czo ...

Standard Steel Casting Company
The Standard Steel Casting Company, commonly referred to as Thurlow Works, was a steel production and steel casting facility founded in Chester, Pennsylvania in 1883 by shipbuilder John Roach. The company was established primarily to supply steel ingots for Roach's steel mills, which included the Chester Rolling Mill and the Combination Steel and Iron Company, although it also manufactured steel castings. Standard Steel was the first company in the United States to manufacture commercial quantities of steel utilizing the acid open hearth process. Roach relinquished majority ownership of the company in 1884 to Robert Wetherill. In subsequent years, Thurlow Works made a name for itself as a manufacturer of large steel castings, especially for the railroad industry. America's first cast steel locomotive frames were poured at Thurlow in 1893. The Standard Steel Casting Company was merged with several other steel casting companies in 1892 to become the American Steel Casting Company. T ...

Combination Steel And Iron Company
The Combination Steel and Iron Company was a steel mill founded in Chester, Pennsylvania by shipbuilder John Roach in 1880. Unlike Roach's other companies, Combination Iron and Steel was initially established not to support the operations of his Chester shipyard, but to produce steel rails and other products for third parties. Roach lost control of the company after his shipbuilding business entered receivership in 1885. History After noting the rapidly growing demand for steel products in the United States, Roach decided to take advantage of it by establishing a second steel mill in addition to his existing mill, the Chester Rolling Mill, which was utilized mainly for supplying steel parts for his ships. Roach raised capital for his new company from a number of business associates including George E. Weed and his brother Charles, Samuel Chalfin, Jerome Keeley and Roach's eldest son John Baker Roach.Swann, pp. 151-152 The Combination Steel and Iron Company was established in 188 ...

Chester Pipe And Tube Company
The Chester Pipe and Tube Company was a company incorporated in 1877 in Chester, Pennsylvania by shipbuilder John Roach for the manufacture of iron pipes and boiler tubes for the steamships built at his Chester shipyard, the Delaware River Iron Ship Building and Engine Works. Incorporated for a sum of $300,000, the Chester Pipe and Tube Company was located on of land at the intersection of Front and West Streets in Chester, adjacent to another Roach company, the Chester Rolling Mill, and close to Roach's shipyard. Two large brick buildings and a number of smaller ones were erected onsite, and a workforce of approximately 200 was employed there. By the early 1880s, the company was manufacturing about 18,000 tons of wrought iron pipes annually from 20,000 tons of skelp iron.
