Thomas Davenport (inventor)
Thomas Davenport (July 9, 1802 – July 6, 1851) was a Vermont blacksmith who constructed the first American DC electric motor in 1834. Biography Davenport was born in Williamstown, Vermont. He lived in Forest Dale, a village near the town of Brandon. As early as 1834, he developed a battery-powered electric motor. He used it to operate a small model car on a short section of track, paving the way for the later electrification of streetcars. Davenport's 1833 visit to the Penfield and Taft iron works at Crown Point, New York, where an electromagnet was operating, based on the design of Joseph Henry, was an impetus for his electromagnetic undertakings. Davenport bought an electromagnet from the Crown Point factory and took it apart to see how it worked. Then he forged a better iron core and redid the wiring, using silk from his wife's wedding gown. With his wife Emily and colleague Orange Smalley, Davenport received the first American patent on an electric machine in 1837 ...

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 ...

People Associated With Electricity
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Vermont Culture
Vermont () is a state in the northeast New England region of the United States. Vermont is bordered by the states of Massachusetts to the south, New Hampshire to the east, and New York to the west, and the Canadian province of Quebec to the north. Admitted to the union in 1791 as the 14th state, it is the only state in New England not bordered by the Atlantic Ocean. According to the 2020 U.S. census, the state has a population of 643,503, ranking it the second least-populated in the U.S. after Wyoming. It is also the nation's sixth-smallest state in area. The state's capital Montpelier is the least-populous state capital in the U.S., while its most-populous city, Burlington, is the least-populous to be a state's largest. For some 12,000 years, indigenous peoples have inhabited this area. The competitive tribes of the Algonquian-speaking Abenaki and Iroquoian-speaking Mohawk were active in the area at the time of European encounter. During the 17th century, French col ...

19th-century American Inventors
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Grafton Page
Charles Grafton Page (January 25, 1812 May 5, 1868) was an American scientist who developed several electrical devices for which he obtained United States patents. He was also a physician, patent examiner, and college professor of chemistry. Like contemporaries Joseph Henry and Michael Faraday, Page began his career as a naturally curious investigator who conducted original research through direct observation and experimentation. Through his experimentation, Page helped develop a scientific understanding of the principles of electromagnetism. Page served as a patent examiner at the United States Patent Office, where his knowledge of electromagnetism was useful in the innovation process and in his own desire to develop electromagnetic locomotion. His work had a lasting impact on telegraphy and in the practice and politics of patenting scientific innovation. Page's views of patenting innovations challenged a commonly held belief at the time that maintained that scientists do not p ...

The Electro-Magnetic And Mechanics Intelligencer
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

Emily Davenport
Emily Goss Davenport Weeks (April 29, 1810October 5, 1862) was an American inventor from Vermont. Together with her husband Thomas Davenport, they invented an electric motor and electric locomotive around 1834. Davenport kept detailed notes and actively contributed to the process of the inventions. Needing to insulate the motor's iron core, Davenport cut her wedding dress into strips of silk to insulate the wire windings. She is also credited with the idea of using mercury as a conductor, enabling the motor to function for the first time. With her husband Thomas, and colleague Orange Smalley, she received the first American patent on an electric machine in 1837, U. S. Patent No. 132. This electric motor was used in 1840 to print '' The Electro-Magnet, and Mechanics Intelligencer'' - the first newspaper printed using electricity. She was born Emily Goss in Brandon Vermont, one of five children born to Rufus Goss a local merchant and Anna Green. She and Thomas Davenport lived ...
