History Of Springfield, Massachusetts
The history of Springfield, Massachusetts dates back to the Colonial history of the United States, colonial period, when it was founded in 1636 as ''Agawam Plantation'', named after a nearby village of Algonkian-speaking Native Americans. It was the northernmost settlement of the Connecticut Colony. The settlement defected from Connecticut after four years, however, later joining forces with the coastal Massachusetts Bay Colony. The town changed its name to ''Springfield'', and changed the political boundaries among what later became the U.S. state, states of New England. The decision to establish a settlement sprang in large part from its favorable geography, situated on a steep bluff overlooking the Connecticut River's confluence with three tributaries. It was a Native American crossroad for two major trade routes: Boston-to-Albany, New York, Albany and New York City-to-Montreal. Springfield also sits on some of the northeastern United States' most fertile soil. Springfield flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siege Of Springfield
The siege of Springfield was a siege of the New England Colonies, colonial New England settlement of Springfield, Massachusetts, Springfield in 1675 by Indigenous peoples of the Americas, Native Americans during King Philip's War. Springfield was the second colonial settlement in New England to be burned to the ground during the war, following Providence Plantations. King Philip's War remains, per capita, the bloodiest war in American history. Background English colonists from Massachusetts Bay Colony established a settlement on the Connecticut River in 1636. They maintained a complex relationship with local Indigenous peoples of the Americas, Indian tribes. The North American fur trade, fur trade stood at the heart of their economic interactions, a lucrative business that guided many other policy decisions. The colonists traded wampum, cloth, and metal in exchange for furs. The tribes sometimes used land as collateral in exchange for colonial goods on the future promise of beaver ...

Small Arms
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries (see legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other explosive propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stabili ...

Charles Goodyear
Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844. Goodyear is credited with inventing the chemical process to create and manufacture pliable, waterproof, moldable rubber. Goodyear's discovery of the vulcanization process followed five years of searching for a more stable rubber and stumbling upon the effectiveness of heating after Thomas Hancock. His discovery initiated decades of successful rubber manufacturing in the Lower Naugatuck Valley in Connecticut, as rubber was adopted to multiple applications, including footwear and tires. The Goodyear Tire and Rubber Company is named after (though not founded by) him. Early life Charles Goodyear was born on December 29, 1800, in New Haven, Connecticut, the son of Amasa Goodyear, and the oldest of six children. His father was a descenda ...

Vulcanized Rubber
Vulcanization (British English: vulcanisation) is a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice. It has also grown to include the hardening of other (synthetic) rubbers via various means. Examples include silicone rubber via RTV silicone, room temperature vulcanizing and chloroprene rubber (neoprene) using metal oxides. Vulcanization can be defined as the curing (chemistry), curing of elastomers, with the terms 'vulcanization' and 'curing' sometimes used interchangeably in this context. It works by forming cross-links between sections of the polymer chain which results in increased rigidity and durability, as well as other changes in the mechanical and electrical properties of the material. Vulcanization, in common with the curing of other thermosetting polymers, is generally irreversible. The word was suggested by William Brockedon (a friend of Thomas ...

Thomas Blanchard (inventor)
Thomas Blanchard (June 24, 1788 – April 16, 1864) was an American inventor who lived much of his life in Springfield, Massachusetts, where in 1819, he pioneered the assembly line style of mass production in America, and also invented the first machining lathe for interchangeable parts. Blanchard worked, for much of his career, with the Springfield Armory. In 1825, Blanchard also invented America's first car, which he called a "horseless carriage," powered by steam. During Blanchard's lifetime, he was awarded over twenty-five patents for his creations.. Biography Tacks He was born in Sutton, Massachusetts. He had a fondness for mechanical employment, and was associated with his brother in the manufacture of tacks by hand. This process was exceedingly slow and tedious,. and his first machine, made and patented in 1806, was a mechanical tack-maker, which could fabricate five hundred tacks per minute, each much better than tacks made by hand. He sold the rights to his machine for $ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assembly Line
An assembly line, often called ''progressive assembly'', is a manufacturing process where the unfinished product moves in a direct line from workstation to workstation, with parts added in sequence until the final product is completed. By mechanically moving parts to workstations and transferring the unfinished product from one workstation to another, a finished product can be assembled faster and with less labor than having workers carry parts to a stationary product. Assembly lines are common methods of assembling complex items such as automobiles and other transportation equipment, household appliances and Consumer electronics, electronic goods. Workers in charge of the works of assembly line are called assemblers. Concepts Assembly lines are designed for the sequential organization of workers, tools or machines, and parts. The motion of workers is minimized to the extent possible. All parts or assemblies are handled either by conveyors or motorized vehicles such as forklif ...

Interchangeable Parts
Interchangeable parts are parts (wikt:component#Noun, components) that are identical for practical purposes. They are made to specifications that ensure that they are so nearly identical that they will fit into any assembly of the same type. One such part can freely replace another, without any custom fitting, such as File (tool), filing. This interchangeability allows easy assembly of new devices, and easier repair of existing devices, while minimizing both the time and skill required of the person doing the assembly or repair. The concept of interchangeability was crucial to the introduction of the assembly line at the beginning of the 20th century, and has become an important element of some modern manufacturing but is missing from other important industries. Interchangeability of parts was achieved by combining a number of innovations and improvements in machining operations and the invention of several machine tools, such as the Henry Maudslay#Lathe design, slide rest lathe ...

Noah Webster
Noah Webster (October 16, 1758 – May 28, 1843) was an American lexicographer, textbook pioneer, English-language spelling reformer, political writer, editor, and author. He has been called the "Father of American Scholarship and Education". He authored a large number of "Blue-Backed Speller" books which were used to teach American children how to spell and read. He is also the author for the modern Merriam-Webster dictionary that was first published in 1828 as '' An American Dictionary of the English Language''. Born in West Hartford, Connecticut, Webster graduated from Yale College in 1778. He passed the bar examination after studying law under Oliver Ellsworth and others but was unable to find work as a lawyer. He found some financial success by opening a private school and writing a series of educational books, including the "Blue-Backed Speller". A strong supporter of the American Revolution and the ratification of the United States Constitution, Webster later criticiz ...

Shays Rebellion
Shays's Rebellion was an armed uprising in Western Massachusetts and Worcester in response to a debt crisis among the citizenry and in opposition to the state government's increased efforts to collect taxes on both individuals and their trades. The fighting took place in the areas around Springfield during 1786 and 1787. Historically, scholars have argued that the four thousand rebels, called ''Shaysites'', who protested against economic and civil rights injustices by the Massachusetts Government were led by Revolutionary War veteran Daniel Shays. By the early 2020s, scholarship has suggested that Shays's role in the protests was significantly and strategically exaggerated by Massachusetts elites, who had a political interest in shifting blame for bad economic conditions away from themselves. In 1787, the protesters marched on the federal Springfield Armory in an unsuccessful attempt to seize its weaponry and overthrow the government. The federal government, severely limited ...
