Holt Manufacturing Company
The Holt Manufacturing Company began with the 1883 founding of Stockton Wheel Service in Stockton, California, United States. Benjamin Holt, later credited with patenting the first workable crawler ("caterpillar") tractor design, incorporated the Holt Manufacturing Company in 1892. Holt Manufacturing Company was the first company to successfully manufacture a continuous track tractor ( Hornsby in England manufactured at least two full length "track steer" machines, and their patent was later purchased by Holt in 1913, allowing Holt to claim to be the "inventor" of the crawler tractor.) By the early 20th century, Holt Manufacturing Company was the leading manufacturer of combine harvesters in the US, and the leading California-based manufacturer of steam traction engines. Holt Manufacturing Company operated from Stockton, California, until opening a satellite facility in Walla Walla, Washington, to serve the Pacific Northwest. In 1909 Holt Manufacturing Company expanded by p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Breach Of Contract
Breach of contract is a legal cause of action and a type of civil wrong, in which a binding agreement or bargained-for exchange is not honored by one or more of the parties to the contract by non-performance or interference with the other party's performance. Breach occurs when a party to a contract fails to fulfill its obligation(s), whether partially or wholly, as described in the contract, or communicates an intent to fail the obligation or otherwise appears not to be able to perform its obligation under the contract. Where there is breach of contract, the resulting damages have to be paid to the aggrieved party by the party breaching the contract. If a contract is rescinded, parties are legally allowed to undo the work unless doing so would directly charge the other party at that exact time. What constitutes a breach of contract There exists two elementary forms of breach of contract. The first is actual failure to perform the contract as and when specified constitutes ...

Line Shaft
A line shaft is a power-driven rotating shaft for power transmission that was used extensively from the Industrial Revolution until the early 20th century. Prior to the widespread use of electric motors small enough to be connected directly to each piece of machinery, line shafting was used to distribute power from a large central power source to machinery throughout a workshop or an industrial complex. The central power source could be a water wheel, turbine, windmill, animal power or a steam engine. Power was distributed from the shaft to the machinery by a system of belts, pulleys and gears known as ''millwork''. Operation A typical line shaft would be suspended from the ceiling of one area and would run the length of that area. One pulley on the shaft would receive the power from a parent line shaft elsewhere in the building. The other pulleys would supply power to pulleys on each individual machine or to subsequent line shafts. In manufacturing where there were a ...

Cape Horn
Cape Horn (, ) is the southernmost headland of the Tierra del Fuego archipelago of southern Chile, and is located on the small Hornos Island. Although not the most southerly point of South America (which is Águila Islet), Cape Horn marks the northern boundary of the Drake Passage and marks where the Atlantic and Pacific Oceans meet. Cape Horn was identified by mariners and first rounded in 1616 by the Dutchmen Willem Schouten and Jacob Le Maire, who named it after the city of Hoorn in the Netherlands. For decades, Cape Horn was a major milestone on the clipper route, by which sailing ships carried trade around the world. The waters around Cape Horn are particularly hazardous, owing to strong winds, large waves, strong currents and icebergs. The need for boats and ships to round Cape Horn was greatly reduced by the opening of the Panama Canal in August 1914. Sailing around Cape Horn is still widely regarded as one of the major challenges in yachting. Thus, a few recreational ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Providence, Rhode Island
Providence () is the List of capitals in the United States, capital and List of municipalities in Rhode Island, most populous city of the U.S. state of Rhode Island. The county seat of Providence County, Rhode Island, Providence County, it is one of the oldest cities in New England, founded in 1636 by Roger Williams, a Reformed Baptist theologian and religious exile from the Massachusetts Bay Colony. He named the area in honor of "God's merciful Providence" which he believed was responsible for revealing such a haven for him and his followers. The city developed as a busy port, as it is situated at the mouth of the Providence River at the head of Narragansett Bay. Providence was one of the first cities in the country to industrialize and became noted for its textile manufacturing and subsequent machine tool, jewelry, and silverware industries. Today, the city of Providence is home to eight hospitals and List of colleges and universities in Rhode Island#Institutions, eight instit ...

Corliss Steam Engine
A Corliss steam engine (or Corliss engine) is a steam engine, fitted with rotary valves and with variable valve timing patented in 1849, invented by and named after the US engineer George Henry Corliss of Providence, Rhode Island. Corliss assumed the original invention from Frederick Ellsworth Sickels (1819- 1895), who held the patent (1829) in the US patent office. Engines fitted with Corliss valve gear offered the best thermal efficiency of any type of stationary steam engine until the refinement of the uniflow steam engine and steam turbine in the 20th century. Corliss engines were generally about 30 percent more fuel efficient than conventional steam engines with fixed cutoff. This increased efficiency made steam power more economical than water power, allowing industrial development away from millponds. Corliss engines were typically used as stationary engines to provide mechanical power to line shafting in factories and mills and to drive dynamos to generate electricit ...

Seasoning (wood)
Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method. There are two main reasons for drying wood: ; Woodworking:When wood is used as a construction material, whether as a structural support in a building or in woodworking objects, it will absorb or expel moisture until it is in equilibrium with its surroundings. Equilibration (usually drying) causes unequal shrinkage in the wood, and can cause damage to the wood if equilibration occurs too rapidly. The equilibration must be controlled to prevent damage to the wood. ; Wood burning: When wood is burned (firewood), it is usually best to dry it first. Damage from shrinkage is not a problem here, as it may be in the case of drying for woodworking purposes. Moisture affects the burning process, with unburnt hydrocarbons going up the chimney. If a 5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Joaquin River
The San Joaquin River ( ; ) is the longest river of Central California. The long river starts in the high Sierra Nevada and flows through the rich agricultural region of the northern San Joaquin Valley before reaching Suisun Bay, San Francisco Bay, and the Pacific Ocean. An important source of irrigation water as well as a wildlife corridor, the San Joaquin is among the most heavily dammed and diverted of California's rivers. People have inhabited the San Joaquin Valley for more than 8,000 years, and it was one of the major population centers of pre-Columbian California. Starting in the late 18th century, successive waves of explorers then settlers, mainly Spanish and American, emigrated to the San Joaquin basin. When Spain colonized the area, they sent soldiers from Mexico, who were usually of mixed native Mexican and Spanish birth, led by Spanish officers. Franciscan missionaries from Spain came with expeditions to evangelize the natives by teaching them about the Catholi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Valley (California)
The Central Valley is a broad, elongated, flat valley that dominates the interior of California, United States. It is wide and runs approximately from north-northwest to south-southeast, inland from and parallel to the Pacific coast. It covers approximately , about 11% of California's land area. The valley is bounded by the California Coast Ranges, Coast Ranges to the west and the Sierra Nevada to the east. The Central Valley is a region known for its agricultural productivity. It provides a large share of the food produced in California, which provides more than half of the fruits, vegetables, and nuts grown in the United States. More than of the valley are irrigated via reservoirs and canals. The valley hosts many cities, including the state capital Sacramento, California, Sacramento, as well as Redding, California, Redding, Chico, California, Chico, Yuba City, California, Yuba City, Woodland, California, Woodland, Davis, California, Davis, Stockton, California, Stockton, M ...

Tiffin, Ohio
Tiffin is a city in Seneca County, Ohio, United States, and its county seat. Developed along the Sandusky River, Tiffin is located about southeast of Toledo, Ohio, Toledo. The population was 17,953 at the 2020 United States census, 2020 census. It is the home of Heidelberg University (Ohio), Heidelberg University and Tiffin University. At one time the city was noted as a glass and porcelain manufacturing center. The National Arbor Day Foundation has designated Tiffin as a Tree City USA. History The bronze statue of "The Indian Maiden" on Frost Parkway near Miami Street, marks the site of Fort Ball, a military depot of the War of 1812. During a fighting engagement of that war, Erastus Bowe sighted the location where Tiffin later developed. In 1817, he returned to the site and built the Pan Yan Tavern on the North Sandusky River. Its name was likely derived from Penn Yan, New York. Early homesteaders followed soon after Bowe, and the settlement of Oakley sprang up around the Pan ...

Hardwood
Hardwood is wood from Flowering plant, angiosperm trees. These are usually found in broad-leaved temperate and tropical forests. In temperate and boreal ecosystem, boreal latitudes they are mostly deciduous, but in tropics and subtropics mostly evergreen. Hardwood (which comes from angiosperm trees) contrasts with softwood (which is from gymnosperm trees). Characteristics Hardwoods are produced by Flowering plant, angiosperm trees that reproduce by flowers, and have broad leaves. Many species are deciduous. Those of temperate regions lose their leaves every autumn as temperatures fall and are dormant in the winter, but those of tropical regions may shed their leaves in response to seasonal or sporadic periods of drought. Hardwood from deciduous species, such as oak, normally shows annual dendrochronology, growth rings, but these may be absent in some tropical timber, tropical hardwoods. Hardwoods have a more complex structure than softwoods and are often much slower growing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Streetcar
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which vehicles, whether individual railcars or multiple-unit trains, run on tramway tracks on urban public streets; some include segments on segregated right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term '' light rail'', which also includes systems separated from other traffic. Tram vehicles are usually lighter and shorter than main line and rapid transit trains. Most trams use electrical power, usually fed by a pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city streets and diesel in more rural environments. Occasionally, trams also carry frei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
