Locking Pliers
Locking pliers (also called Vise-Grips, Mole wrench or Mole grips) are pliers that can be locked into position, using an "over-center" cam action. Locking pliers are available with many different jaw styles, such as needle-nose pliers, wrenches, clamps and various shapes to fix metal parts for welding. They also come in many sizes. History The first locking pliers, with the trade name Vise-Grip, were invented by William S. Petersen in De Witt, Nebraska, United States in 1924. Later, in 1955, in the United Kingdom, M K Mole and Son, a hand tool manufacturing company, under the managing direction of Thomas Coughtrie, began making nearly identical pliers. Etymology In the United States, the brand name "''Vise-Grips''" is close to a generic name for this type of pliers. The same is true in the United Kingdom of the brand name "''Mole Wrench''". The spelling "''vise''" is mentioned in Samuel Johnson's 1755 dictionary. This spelling is orthodox in the United States. The sp ...

Irwin Industrial Tools
Irwin Industrial Tools is an American manufacturer and distributor of hand tools and power tool accessories. It is owned by Stanley Black & Decker. It is best known for producing Vise-Grip locking pliers. Additionally, it produces clamps, drill bits, taps and dies, screw extractors, bolt extractors, saw blades, pipe wrenches, screwdrivers, snips, and other construction tools. History Irwin was founded in 1885 in Martinsville, Ohio as the Irwin Auger Bit Company by Charles Irwin, a pharmacist. Irwin had bought the rights to a solid-center auger bit from a local blacksmith. In 1924, another blacksmith, Danish immigrant William Petersen of DeWitt, Nebraska, invented the first locking pliers and named them Vise-Grips. In 1934, Petersen formed the Petersen Manufacturing Company to produce them. In 1957, Petersen added an easy-release trigger to the design, creating the modern locking pliers design. In 1985, American Tool Companies bought out Petersen Manufacturing. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oxford English Dictionary
The ''Oxford English Dictionary'' (''OED'') is the principal historical dictionary of the English language, published by Oxford University Press (OUP), a University of Oxford publishing house. The dictionary, which published its first edition in 1884, traces the historical development of the English language, providing a comprehensive resource to scholars and academic researchers, and provides ongoing descriptions of English language usage in its variations around the world. In 1857, work first began on the dictionary, though the first edition was not published until 1884. It began to be published in unbound Serial (literature), fascicles as work continued on the project, under the name of ''A New English Dictionary on Historical Principles; Founded Mainly on the Materials Collected by The Philological Society''. In 1895, the title ''The Oxford English Dictionary'' was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in 10 b ...

Pliers
Pliers are a hand tool used to hold objects firmly, possibly developed from tongs used to handle hot metal in Bronze Age Europe. They are also useful for bending and physically compressing a wide range of materials. Generally, pliers consist of a pair of metal first-class levers joined at a fulcrum positioned closer to one end of the levers, creating short ''jaws'' on one side of the fulcrum, and longer handles on the other side. This arrangement creates a mechanical advantage, allowing the force of the grip strength to be amplified and focused on an object with precision. The jaws can also be used to manipulate objects too small or unwieldy to be manipulated with the fingers. Diagonal pliers, also called side cutters, are a similarly shaped tool used for cutting rather than holding, having a pair of stout blades, similar to scissors except that the cutting surfaces meet parallel to each other rather than overlapping. Ordinary (holding/squeezing) pliers may incorporate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Popular Mechanics
''Popular Mechanics'' (often abbreviated as ''PM'' or ''PopMech'') is a magazine of popular science and technology, featuring automotive, home, outdoor, electronics, science, do it yourself, and technology topics. Military topics, aviation and transportation of all types, space, tools and gadgets are commonly featured. It was founded in 1902 by Henry Haven Windsor, who was the editor and—as owner of the Popular Mechanics Company—the publisher. For decades, the tagline of the monthly magazine was "Written so you can understand it." In 1958, PM was purchased by the Hearst Corporation, now Hearst Communications. In 2013, the US edition changed from twelve to ten issues per year, and in 2014 the tagline was changed to "How your world works." The magazine added a podcast in recent years, including regular features ''Most Useful Podcast Ever'' and ''How Your World Works''.

Popular Science
Popular science (also called pop-science or popsci) is an interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is more broad ranging. It may be written by professional science journalists or by scientists themselves. It is presented in many forms, including books, film and television documentaries, magazine articles, and web pages. History Before the modern specialization and professionalization of science, there was often little distinction between "science" and "popular science", and works intended to share scientific knowledge with a general reader existed as far back as Greek and Roman antiquity. Without these popular works, much of the scientific knowledge of the era might have been lost. For example, none of the original works of the Greek astronomer Eudoxus (4th century BC) have survived, but his contributions were largely preserved due to the didactic poem '' Phenomena'' writte ...

Welding
Welding is a fabrication (metal), fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melting, melt the parts together and allow them to cool, causing Fusion welding, fusion. Common alternative methods include solvent welding (of thermoplastics) using chemicals to melt materials being bonded without heat, and #Solid-state welding, solid-state welding processes which bond without melting, such as pressure, cold welding, and diffusion bonding. Metal welding is distinct from lower temperature bonding techniques such as brazing and soldering, which do not melt the base metal (parent metal) and instead require flowing a filler metal to solidify their bonds. In addition to melting the base metal in welding, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that can be stronger than the base material. Welding also requires a form of shield to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Samuel Johnson
Samuel Johnson ( – 13 December 1784), often called Dr Johnson, was an English writer who made lasting contributions as a poet, playwright, essayist, moralist, literary critic, sermonist, biographer, editor, and lexicographer. The ''Oxford Dictionary of National Biography'' calls him "arguably the most distinguished man of letters in English history". Born in Lichfield, Staffordshire, he attended Pembroke College, Oxford, until lack of funds forced him to leave. After working as a teacher, he moved to London and began writing for ''The Gentleman's Magazine''. Early works include '' Life of Mr Richard Savage'', the poems ''London'' and '' The Vanity of Human Wishes'' and the play '' Irene''. After nine years of effort, Johnson's '' A Dictionary of the English Language'' appeared in 1755, and was acclaimed as "one of the greatest single achievements of scholarship". Later work included essays, an annotated '' The Plays of William Shakespeare'', and the apologue '' The Hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A Dictionary Of The English Language
''A Dictionary of the English Language'', sometimes published as ''Johnson's Dictionary'', was published on 15 April 1755 and written by Samuel Johnson. It is among the most influential dictionary, dictionaries in the history of the English language. There was dissatisfaction with the dictionaries of the period, so in June 1746 a group of London booksellers contracted Johnson to write a dictionary for the sum of 1,500 Guinea (British coin), guineas (£1,575), equivalent to about £ in . Johnson took seven years to complete the work, although he had claimed he could finish it in three. He did so single-handedly, with only clerical assistance to copy the illustrative quotations that he had marked in books. Johnson produced several revised editions during his life. Until the completion of the ''Oxford English Dictionary'' 173 years later, Johnson's was viewed as the pre-eminent English dictionary. According to Walter Jackson Bate, the Dictionary "easily ranks as one of the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thomas Coughtrie
Thomas Robb Coughtrie (25 November 1917 – 27 August 2008) was a chartered engineer from Motherwell, Lanarkshire, Scotland. He was credited by ''The Times'' as the inventor of the self-grip Mole wrench although this conflicts with other sources which show the invention of the Vise-Grip locking pliers in Nebraska, United States, with an initial patent in 1921 and fuller developments patented in 1924. Biography It could be surmised that M. K. Mole and Son produced their own version (the Mole Grip) based on the existing American Vise-Grip. The likeness between the two is clear even from sketch drawings. He was born in Motherwell, Lanarkshire, Scotland. After his education at Bellshill Academy he qualified as a chartered engineer. During the Second World War, he was an electrical engineer involved in the maintenance of 1,000 ton 'Whale' floating roadways for Mulberry harbours. In 1947 he started working for the Birmingham engineering firm of M. K. Mole and Son, founded in 1835. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
