Elisha Root
Elisha King Root (May 5, 1808 - September 1, 1865) was a Connecticut machinist, inventor, and President of Colt's Manufacturing Company. Root was born on a Massachusetts farm and worked as a bobbin boy in a cotton mill before switching, at the age of 15, to working in a machine shop in Ware, Massachusetts. At age 24 he was hired by Connecticut industrialist Samuel W. Collins to work in his axe factory in Collinsville, a village of Canton, Connecticut. According to historian Diana Muir writing in Reflections in Bullough's Pond, Root "reconceptualized" the making of axes. Until his invention, axes were made by "flattening wrought iron, folding it around a steel pin, and forging the two sides together under a trip hammer." Root arranged "a series of dies and rollers that could 'die forge' -or apply pressure to a mold, forming a piece of hot wrought iron into the shape of an ax, with an eye already punched to receive the handle." According to Muir, Root next automated the temperi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludlow, Massachusetts
Ludlow is a New England town in Hampden County, Massachusetts, United States. The population was 21,002 as of the 2020 census, and it is considered part of the Springfield Metropolitan Statistical Area. Located just northeast of Springfield across the Chicopee River, it is one of the city's suburbs. It has a sizable and visible Portuguese and Polish community. History The Indigenous people along the Chicopee River, including modern-day Ludlow, were the Algonquian peoples. Though records are incomplete, the area was settled primarily by the Pocomtuc tribe. During King Philip’s War (1675–1676), white settlers forced a band of Indigenous people, led by Roaring Thunder, to jump to the water of the Chicopee River to escape their attackers (this place has since been called Indian Leap). This violent incident contributed to conditions later allowing more white settler colonialism in the area. Although plans were drawn up for settlement as early as 1685, within the original boun ...

Power Hammer
Power hammers are mechanical forging hammers that use an electrical power source or steam to raise the hammer preparatory to striking, and accelerate it onto the work being hammered. They are also called open die power forging hammers. They have been used by blacksmiths, bladesmiths, metalworkers, and manufacturers since the late 1880s, having replaced trip hammers. Design and operation A typical power hammer consists of a frame, an anvil, and a reciprocating ram holding a hammer head or die. The workpiece is placed on the lower anvil or die and the head or upper die strikes the workpiece. The power hammer is a direct descendant of the trip hammer, differing in that the power hammer stores potential energy in an arrangement of mechanical linkages and springs, in compressed air, or steam, and by the fact that it accelerates the ram on the downward stroke. This provides more force than simply allowing the weight to fall. Predecessors like trip hammers, steam drop hammers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Connecticut Industry
The history of Connecticut Industry is a major part of the history of Connecticut. Between the birth of the U.S. patent system in 1790 and 1930, Connecticut had more patents issued per capita than any other state; in the 19th century, when the U.S. as a whole was issued one patent per three thousand population, Connecticut inventors were issued one patent for every 700–1000 residents. Connecticut's first recorded invention was a lapidary machine, by Abel Buell of Killingworth, in 1765. Pre-industrialization Connecticut began, as most communities at the time, as a farming economy. It rapidly developed trade and manufacturing as the farmers, and then the merchants and manufacturers themselves, became affluent enough to start buying things. Manufacturing was aided by a plenitude of resources, including water power, wood for fires and building material, and iron ore, while transportation benefited from several excellent natural harbors, and navigable rivers leading all the way t ...

American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robbins And Lawrence Company
The American Precision Museum is located in the renovated 1846 Robbins & Lawrence factory on South Main Street in Windsor, Vermont. The building is said to be the first U.S. factory at which precision interchangeable parts were made, giving birth to the precision machine tool industry. In recognition of this history, the building was declared a National Historic Landmark in 1966. and In 1987, the building was recognized by the American Society of Mechanical Engineers as an International Heritage Site, and the collection was recognized as an International Heritage Collection. For each of these designations, the armory was considered a site where pivotal events occurred in the history of American industry, as well as a place that lends itself to comprehensive interpretation of that history. A "machine tool" is a machine which makes parts to other machines, such as screws or gun stocks. Lathes, milling machines, and drill presses are examples of precision machine too ...

Simeon North
Simeon North (July 13, 1765 – August 25, 1852) was a Middletown, Connecticut, gun manufacturer, who developed one of America's first milling machines (possibly the very first) in 1818 and played an important role in the development of interchangeable parts manufacturing. North was born in Berlin, Connecticut, into a prosperous family able to provide all six sons with farms of their own. North was given a farm in Berlin, a gift that enabled him to marry Lucy Savage when he was only twenty-one years old; the couple had five sons and three daughters. In 1795 the Norths purchased a sawmill located on the brook that ran beside their land. Simeon hired a man to help run it, enlarged the building to house a forge and trip-hammer, and began manufacturing scythes from imported steel. Four years later, he obtained a contract to make pistols and began to add a factory to the mill building. North's brother-in-law Elisha Cheney was a skilled clockmaker, a trade he had learned from his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milling Machine
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done by varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances. Milling can be done with a wide range of machine tools. The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into ''machining centers'': milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant systems, and enclosures. Milling centers are generally classified as vertical machining centers (VMCs) or horizontal machining centers (HMCs). The integra ...
