William Lyman (inventor)
William Worcester Lyman (March 29, 1821 – November 15, 1891) was an American inventor from Meriden, Connecticut. He is credited with inventing the first rotating wheel can opener. William Lyman was born in 1821 in Middlefield, Connecticut. At the age of 15 he was apprenticed to the local company Griswold & Couch, located in Meriden, Connecticut, to learn pewter Pewter () is a malleable metal alloy consisting of tin (85–99%), antimony (approximately 5–10%), copper (2%), bismuth, and sometimes silver.

After that, he continued working as a pewtersmith with various local companies until 1880. In 1849, he was appointed as State Representative in Meriden. On September 5, 1841 William married Roxanne Griswold Frary, a local woman one year older than he was. He died in Meriden in 1891 at the age of 70. Lyman was a dedicated inventor, ...

Middlefield is a town in Middlesex County, Connecticut, United States. The population was 4,217 at the 2020 census. The town includes the village of Rockfall in the northeast section. History Middlefield, in Middlesex County, is so named because it is halfway between Middletown and Durham, and Middletown and Meriden. For such a small community, Middlefield has an abundance of wonderful history that goes back to the late 17th century and many first settlers of Connecticut. The Old North Burying Ground was established for those living west of Middletown and the first burial was in 1738. Middlefield became a town in 1866 by an act of the Connecticut Legislature.

Can Opener
A can opener (in North American English and Australian English) or tin opener (used in British English) is a mechanical device used to open tin cans (metal cans). Although canning, preservation of food using tin cans had been practiced since at least 1772 in the Netherlands, the first can openers were not patented until 1855 in England and 1858 in the United States. These early openers were basically variations of a knife, though the 1855 design continues to be produced. The first can opener, consisting of the now familiar sharp rotating cutting wheel that runs round the can's rim to cut open the lid, was invented in 1870, but was considered very difficult to operate for the ordinary consumer. A successful design came out in 1925 when a second, serrated wheel was added to hold the cutting wheel on the rim of the can. This easy-to-use design has become one of the most popular can opener models. Around the time of World War II, several can openers were developed for military us ...

Pewter
Pewter () is a malleable metal alloy consisting of tin (85–99%), antimony (approximately 5–10%), copper (2%), bismuth, and sometimes silver. Copper and antimony (and in antiquity lead) act as hardeners, but lead may be used in lower grades of pewter, imparting a bluish tint. Pewter has a low melting point, around , depending on the exact mixture of metals. The word ''pewter'' is probably a variation of the word ''spelter'', a term for zinc alloys (originally a colloquial name for zinc). History Pewter was first used around the beginning of the Bronze Age in the Near East. The earliest known piece of pewter was found in an Egyptian tomb, c. 1450 BC, but it is unlikely that this was the first use of the material. Pewter was used for decorative metal items and tableware in ancient times by the Egyptians and later the Romans, and came into extensive use in Europe from the Middle Ages until the various developments in pottery and glass-making during the 18th and 19th centuries. ...

Nut (hardware)
A nut is a type of fastener with a screw thread, threaded hole. Nuts are almost always used in conjunction with a mating bolt (fastener), bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight deformation (engineering)#Elastic deformation, elastic deformation), a slight Tension (physics), stretching of the bolt, and compression (physics), compression of the parts to be held together. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, eccentric double nuts, specialist adhesive thread-locking fluid such as Loctite, safety pins (split pins) or lockwire in conjunction with castellated nuts, nylon inserts (nyloc nut), or slightly oval-shaped threads. Square nuts, as well as bolt heads, were the first shape made and used to be the most common largely because they were much easier to manufacture, especially by hand. While rare to ...

Charles's Law
Charles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion. This relationship of direct proportion can be written as: :V \propto T So this means: :\frac = k, \quad \text \quad V=k T where: * is the volume of the gas, * is the temperature of the gas (measured in kelvins), and * is a non-zero constant. This law describes how a gas expands as the temperature increases; conversely, a decrease in temperature will lead to a decrease in volume. For comparing the same substance under two different sets of conditions, the law can be written as: \frac=\frac The equation shows that, as absolute temperature increases, the volume of the gas also increases in proportion. History The law was named after scientist Jacques Charles, who formulated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
