Walter Hunt (inventor)
Walter Hunt (July 29, 1796 – June 8, 1859) was an American mechanical engineer. Through the course of his work he became known for being a prolific inventor. He got first involved with mechanical innovations in a linseed producing community in New York state that had flax mills. While in New York City to promote his inventions he got involved in inventing the streetcar gong that was used throughout the United States. This then led him to invent other useful items like the safety pin and sewing machine. He invented the precursor to the repeating rifle and fountain pen. About two dozen of his inventions are used today in basically the same form as he had patented them. In spite of his many useful innovative creations he never became wealthy since he sold off most of his patent rights to others at low prices with no future royalties. Others made millions of dollars from his safety pin device. Early life and education Walter Hunt was born July 29, 1796, in the town of Martinsbu ...

Safety Pin
The safety pin is a variation of the regular pin which includes a simple spring mechanism and a clasp. The clasp forms a closed loop to properly fasten the pin to whatever it is applied to and covers the end of the pin to protect the user from the sharp point. Safety pins are commonly used to fasten pieces of fabric or clothing together. Safety pins, or more usually a special version with an extra safe cover, called a nappy or loincloth pin, are widely used to fasten cloth diapers (nappies), or modern loincloths. They're preferred as their safety clasp, while remaining an ingestion hazard, prevents the baby from being jabbed or pricked. Safety pins can be used generally to patch torn or damaged clothing. They can also be used as an accessory in all kinds of jewelry including: earrings, chains, and wristbands. Sometimes they're used to attach an embroidered patch. Safety pins are divided into numbered size categories. With size 3 pins often being used in quilting and may be labelle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velocipedes
A velocipede () is a human-powered land vehicle with one or more wheels. The most common type of velocipede today is the bicycle. The term was probably first coined by Karl von Drais in French as ''vélocipède'' for the French translation of his advertising leaflet for his version of the ''Laufmaschine'', also now called a 'dandy horse', which he had developed in 1817. It is ultimately derived from the Latin ''velox'', ''veloc-'' 'swift' + ''pes'', ''ped-'' 'foot'.''Oxford Dictionary of English'', 'velocipede' The term 'velocipede' is today mainly used as a collective term for the different forerunners of the monowheel, the unicycle, the bicycle, the dicycle, the tricycle and the quadracycle developed between 1817 and 1880. It refers especially to the forerunner of the modern bicycle that was propelled, like a modern tricycle, by cranks, i.e. pedals, attached to the front axle before the invention of geared chains and belt and shaft drives powering the rear.

Mail Sorting
Mail sorting refers to the methods by which postal systems determine how and where to route mail for delivery. Once accomplished by hand, mail sorting is now largely automated through the aid of specialized machines. The first widely adopted mail sorting machine was the Transorma, first made operational in Rotterdam in 1930. Mail sorting systems are now also used by corporations and other mailers to presort mail prior to delivery in order to earn discounts on postage. In the United States, for example, presort discounts can reduce the cost of First-Class Mail from $0.42 to as low as $0.324. Many companies also use mail sorters to handle incoming mail such as checks, orders and correspondence. History For much of the 20th century, mail was sorted by hand using what is called a "pigeon-hole messagebox" method. Addresses were read and manually slotted into specific compartments. Early forms of a mechanical mail sorter were developed and tested in the 1920s. The Transorma, manufa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Street Sweeper
A street sweeper or street cleaner may refer to a person's occupation or to a machine that cleans streets. Street sweepers have been employed in cities as "sanitation workers" since sanitation and waste removal became a priority. A street-sweeping person would use a broom and shovel to clean off litter, animal waste and filth that accumulated on streets. Later, water hoses were used to wash the streets. Machines were created in the 19th century to do the job more efficiently. Today, modern street sweepers are mounted on truck bodies and can vacuum debris that accumulates in streets. Modern sweepers Street sweepers are capable of collecting small particles of debris. Many street sweepers produced today are PM10 and PM2.5 certified, meaning that they are capable of collecting and holding particulate matter sized less than 10μm and even down to 2.5μm. Despite advancements in street sweeping technology, the mechanical broom type street sweeper accounts for approximat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winchester Repeating Rifle
Winchester rifle is a comprehensive term describing a series of lever action repeating rifles manufactured by the Winchester Repeating Arms Company. Developed from the 1860 Henry rifle, Winchester rifles were among the earliest repeaters. The Model 1873 was particularly successful, being marketed by the manufacturer as "The Gun That Won the West". Predecessors In 1848, Walter Hunt of New York patented his "Volition Repeating Rifle" incorporating a tubular magazine, which was operated by two levers and complex linkages. The Hunt rifle fired what he called the "Rocket Ball", an early form of caseless ammunition in which the powder charge was contained in the bullet's hollow base. Hunt's design was fragile and unworkable, but in 1849, Lewis Jennings purchased the Hunt patents and developed a functioning, if still complex rifle. This version was produced in small numbers by Robbins & Lawrence of Windsor, Vermont until 1852. Horace Smith and Daniel Wesson of Norwich, Connecti ...

Masonry
Masonry is the building of structures from individual units, which are often laid in and bound together by mortar; the term ''masonry'' can also refer to the units themselves. The common materials of masonry construction are bricks, building stone such as marble, granite, and limestone, cast stone, concrete blocks, glass blocks, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction trades. Applications Masonry is commonly used for walls and buildings. Brick and concrete block are the most common types of masonry in use in industrialized nations and may be either load-bearing or non-load-bearing. Concrete blocks, especially those with hollow cores, offer va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

One-room Schoolhouse
One-room schools, or schoolhouses, were commonplace throughout rural portions of various countries, including Prussia, Norway, Sweden, the United States, Canada, Australia, New Zealand, the United Kingdom, Ireland, and Spain. In most rural and small town schools, all of the students met in a single room. There, a single teacher taught academic basics to several grade levels of elementary-age children. While in many areas one-room schools are no longer used, some remain in developing nations and rural or remote areas. In the United States, the concept of a "little red schoolhouse" is a stirring one, and historic one-room schoolhouses have widely been preserved and are celebrated as symbols of frontier values and of local and national development. When necessary, the schools were enlarged or replaced with two-room schools. More than 200 are listed on the U.S. National Register of Historic Places. In Norway, by contrast, one-room schools were viewed more as impositions upon conse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lewis County, New York
Lewis County is a county located in the U.S. state of New York. As of the 2020 census, the population was 26,582, making it the fourth-least populous county in New York. Its county seat is Lowville. The county is named after Morgan Lewis, the Governor of New York when the county was established. History The area now occupied by Lewis County was very sparsely occupied until the end of the 18th century. Although the land was already claimed by the Province of New York in its original grant, the land was clearly part of the territory of the Iroquois confederacy until after the American Revolutionary War, when New York seized the lands from tribes that had supported the British. The lands were unsurveyed and remained unattractive to settlement until after the complex process of Macomb's Purchase of 1791 eventually put much of the land in the hands of John Brown.

Royalties
A royalty payment is a payment made by one party to another that owns a particular asset, for the right to ongoing use of that asset. Royalties are typically agreed upon as a percentage of gross or net revenues derived from the use of an asset or a fixed price per unit sold of an item of such, but there are also other modes and metrics of compensation.Guidelines for Evaluation of Transfer of Technology Agreements, United Nations, New York, 1979 A royalty interest is the right to collect a stream of future royalty payments. A license agreement defines the terms under which a resource or property are licensed by one party to another, either without restriction or subject to a limitation on term, business or geographic territory, type of product, etc. License agreements can be regulated, particularly where a government is the resource owner, or they can be private contracts that follow a general structure. However, certain types of franchise agreements have comparable provisions. N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...
