Plumber Wrench
A plumber wrench (or plumber's wrench, pipe wrench, Swedish wrench or Swedish pattern wrench) is a form of plier described as a pipe wrench that uses compound leverage to grip and rotate plumbing pipes. Similar to the action of a Vise Grip plier, its jaw opening is adjusted to width by rotating a threaded ring. Its advantage is that it grips with significant force without needing to engage a lock nut like an adjustable tongue-and-groove plier. Like these, it can also be used on nuts, particularly hex shaped, and other flat engagement points. If used carelessly it can dent or break plumbing pipe. History The plumber wrench was invented in 1888 by the Swedish inventor named Johan Petter Johansson. It shares some principles with both the Stillson-pattern pipe wrench and the rigid pipe wrench, as well as various forms of adjustable pliers, such as the Vise Grip and "Channelock" tongue-and-groove plier. Johansson's tool is used rather than a pair of tongs to separate or join ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A plumber is a tradesperson who specializes in installing and maintaining systems used for potable (drinking) water, and for sewage and drainage in plumbing systems.Employment and Occupations in the Skilled Trades in Michigan , Michigan Department of Technology, Management, and Budget, Bureau of Labor Market Information and Strategic Initiatives (June 2013).

Stillson Wrench
A pipe wrench is any of several types of wrench that are designed to turn threaded pipe and pipe fittings for assembly (tightening) or disassembly (loosening). The Stillson wrench, or Stillson-pattern wrench, is the usual form of pipe wrench, especially in North America. The Stillson name is that of the original patent holder, who licensed the design to a number of manufacturers. The patent expired decades ago. Another type of wrench often used on pipes, the plumber wrench, is also called a pipe wrench in some places. The Stillson wrench is an adjustable wrench (spanner) with hardened serrated teeth on its jaws. The hard teeth bite into the softer metal of the round pipe and provide the grip needed to turn a pipe, even against fair resistance. The design of the adjustable jaw, which permits a certain amount of intentional play out of square, allows it to bind on the pipe, with forward pressure on the handle pulling the jaws tighter. On some models, two leaf springs, above and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumbing
Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids. Heating and cooling (HVAC), waste removal, and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications. The word derives from the Latin for lead, ''plumbum'', as the first effective pipes used in the Roman era were lead pipes. In the developed world, plumbing infrastructure is critical to public health and sanitation. Boilermakers and pipefitters are not plumbers although they work with piping as part of their trade and their work can include some plumbing. History Plumbing originated during ancient civilizations, as they developed public baths and needed to provide potable water and wastewater removal for larger numbers of people. The Mesopotamians introduced the world to clay sewer pipes around 4000 BCE, with the earliest examples found i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monkey Wrench
The monkey wrench is a type of adjustable wrench, a 19th century American refinement of 18th-century English coach wrenches. It was widely used in the 19th and early 20th century. It is of interest as an antique among tool collectors and is still occasionally used in maintenance and repair when it happens to be convenient. The term ''monkey wrench'' is also sometimes used loosely, usually by non-tradesman, to refer to the pipe wrench (owing to their broadly similar shapes). A wrench with smooth jaws is not used for turning threaded pipe. The largely US idiom "to throw a monkey wrench into..." means to sabotage something. The British English equivalent is "to throw a spanner in the works". The phrase "left handed monkey wrench" is sometimes used as ironic humor, as monkey wrenches are ambidextrously designed. Etymology and history The ''World English Dictionary'' gives a nautical definition for ''monkey'', as a modifier "denoting a small light structure or piece of equipme ...

Adjustable Wrench
An adjustable spanner (UK and most other English-speaking countries) or adjustable wrench (US and Canada) is any of various styles of spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner. There are many forms of adjustable spanners; many of them are screw-adjusted, whereas others use levers, and some early ones used wedges. Forms and names There are many forms of adjustable spanners; many of them are screw-adjusted, whereas others use levers, and some early ones used wedges. The early taper-locking spanners needed a hammer to set the movable jaw to the size of the nut. The modern screw-adjusted spanner and lever types are easily and quickly adjusted. Some adjustable spanners automatically adjust to the size of the nut, using a motor and battery. Simpler models use a serrated edge to lock the movable jaw to size, while more sophisticated ve ...

Tongs
Tongs are a type of tool used to grip and lift objects instead of holding them directly with hands. There are many forms of tongs adapted to their specific use. The first pair of tongs belongs to the Egyptians. Tongs likely started off as basic wooden tongs and then over time progressed to bronze bars as early as 3000BC. Over time they progressed to what we now know as modern-day tongs. An Egyptian wall painting from 1450 BCE shows a crucible supported between two metal bars. The same painting shows someone holding a small object over a fire with a tong-like instrument. Bronze loops capable of handling heavy crucibles also happened to appear at this time. # Tongs that have long arms terminating in small flat circular ends of tongs and are pivoted at a joint close to the handle used to handle delicate objects. Common fire-tongs, used for picking up pieces of coal and placing them on a fire without burning fingers or getting them dirty are of this type. Tongs for grilling, to ...

Tongue-and-groove Pliers
Tongue-and-groove pliers are a type of slip-joint pliers. They are also known as: * adjustable pliers, * Channellocks ( i.e., Channellock brand pliers), * water pump pliers, * groove-joint pliers, * arc-joint pliers, * Multi-Grips, * tap or pipe spanners, * swan neck pliers. * Monkey pliers. Design They have serrated jaws generally set 45 to 60 degrees from the handles. The lower jaw can be moved to a number of positions by sliding along a tracking section under the upper jaw. An advantage of this design is that the pliers can adjust to a number of sizes without the distance in the handle growing wider. These pliers often have long handles—commonly 9.5 to 12 inches long—for increased leverage. The weight of the tool can also vary, depending on the material used. Uses Tongue-and-groove pliers are commonly used for turning and holding nuts and bolts, gripping irregularly shaped objects, and clamping materials. It is also possible to rotate objects while keeping them in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johan Petter Johansson
Johan Petter Johansson (December 12, 1853 – August 25, 1943), sometimes known as JP, was a Swedish inventor and industrialist. He invented a modern adjustable spanner (patents in 1891 and 11 May 1892). He obtained over 100 patents in total. He was born in Vårgårda in western Sweden, the oldest of six children in a crofter's family. His first employment was as an assistant operator of a steam engine at a local peat factory. He left Vårgårda at age 19, in 1873, for Motala to work as a navvy. Following military service in 1874, he moved to Eskilstuna where he worked for the Bolinder-Munktell factory, and in 1878 he moved to Västerås where he found employment at a mechanical workshop. Following that, he worked as a blacksmith at a nearby farm. At this time, he had made a decision to leave Sweden for the United States. This never happened; he was instead offered a more esteemed job by his former employer Munktells, and the offer changed his mind. In 1886 he decided to start ...
