Treadmill
A treadmill is a device generally used for walking, running, or climbing while staying in the same place. Treadmills were introduced before the development of powered machines to harness the power of animals or humans to do work, often a type of mill operated by a person or animal treading the steps of a treadwheel to grind grain. In later times, treadmills were used as punishment devices for people sentenced to hard labor in prisons. The terms ''treadmill'' and ''treadwheel'' were used interchangeably for the power and punishment mechanisms. More recently, treadmills have instead been used as exercise machines for running or walking in one place. Rather than the user powering a mill, the device provides a moving platform with a wide conveyor belt driven by an electric motor or a flywheel. The belt moves to the rear, requiring the user to walk or run at a speed matching the belt. The rate at which the belt moves is the rate of walking or running. Thus, the speed of running may b ...

William Staub
William Edward Staub (November 3, 1915 – July 19, 2012) was an American mechanical engineer who invented and developed the first consumer treadmill for home use, the PaceMaster 600, during the late 1960s. Dr. Kenneth H. Cooper, who helped to popularize Staub's invention, has described Staub as "a pioneer in exercise — not for the athlete, but for the masses." Life Staub was born in Philadelphia, Pennsylvania, on November 3, 1915. He lived in Clifton, New Jersey, for most of his life, residing in the town for more than seventy years. He originally moved to New Jersey to work as an engineer for the propeller division of Curtiss-Wright, an aircraft manufacturer, during World War II. He later founded the Besco Corp., an aerospace components producer headquartered in Clifton, New Jersey. The name "Besco" stood for the "Bill Edward Staub Corporation." Staub developed the first consumer treadmill after reading the 1968 book, ''Aerobics'', by Dr. Kenneth H. Cooper. Cooper's book noted ...

Treadwheel
A treadwheel, or treadmill, is a form of engine typically powered by humans. It may resemble a water wheel in appearance, and can be worked either by a human treading paddles set into its circumference (treadmill), or by a human or animal standing inside it (treadwheel). These devices are no longer used for power or punishment, and the term "treadmill" has come to mean an exercise machine for running or walking in place. History Uses of treadwheels included raising water, to power cranes, or grind grain. They were used extensively in the Greek and Roman world, such as in the reverse overshot water-wheel used for dewatering purposes. They were widely used in the Middle ages to lift the stones in the construction of Gothic cathedrals. There is a literary reference to one in 1225, and one treadwheel crane survives at Chesterfield, Derbyshire and is housed in the Museum. It has been dated to the early 14th century and was housed in the top of the church tower until its removal in 1947 ...

Brixton (HM Prison)
HM Prison Brixton is a local men's prison, located in Brixton area of the London Borough of Lambeth, in inner-South London. The prison is operated by His Majesty's Prison Service. History The prison was originally built in 1820 and opened as the ''Surrey House of Correction'', Brixton Prison was intended to house 175 prisoners. However, regularly exceeding its capacity supporting over 200 prisoners, overcrowding was an early problem and with its small cells and poor living conditions contributed to its reputation as one of the worst prisons in London (worsened when Brixton became one of the first prisons to introduce penal treadmills in 1821). There is an illustration of prisoners on the 1821 treadmill used to mill corn in Surrey House of Correction. Conditions for women were especially harsh as newly arrived female inmates were made to spend four months in solitary confinement and, following their introduction into the general prison population, would be required to maintai ...

William Cubitt
Sir William Cubitt FRS (bapt. 9 October 1785 – 13 October 1861) was an eminent English civil engineer and millwright. Born in Norfolk, England, he was employed in many of the great engineering undertakings of his time. He invented a type of windmill sail and the prison treadwheel, and was employed as chief engineer, at Ransomes of Ipswich, before moving to London. He worked on canals, docks, and railways, including the South Eastern Railway and the Great Northern Railway. He was the chief engineer of Crystal Palace erected at Hyde Park in 1851. He was president of the Institution of Civil Engineers between 1850 and 1851. Early life Cubitt was born in Dilham, Norfolk, the son of Joseph Cubitt of Bacton Wood, a miller, and Hannah Lubbock. He attended the village school. His father moved to Southrepps, and William at an early age was employed in the mill, but in 1800 was apprenticed to James Lyon, a cabinet-maker at Stalham, from whom he parted after four years. At Bacton ...

Mill (grinding)
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind (windmill) or water (watermill). In modern era, they are usually powered by electricity. The grinding of solid materials occurs through mechanical forces that break up the structure by overcoming the interior bonding forces. After the grinding the state of the solid is changed: the grain size, the grain size disposition and the grain shape. Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construction purp ...

Treadwheel Crane
A treadwheel crane (Latin: ''magna rota'') is a wooden, human powered hoisting and lowering device. It was primarily used during the Roman period and the Middle Ages in the building of castles and cathedrals. The often heavy charge is lifted as the individual inside the treadwheel crane walks. The rope attached to a pulley is turned onto a spindle by the rotation of the wheel thus allowing the device to hoist or lower the affixed pallet. History Ancient Rome The Roman ''Polyspaston'' crane, from Ancient Greek πολύσπαστον (polúspaston, “compound pulley”), when worked by four men at both sides of the winch, could lift 3000  kg. In case the winch was replaced by a treadwheel, the maximum load even doubled to 6000 kg at only half the crew, since the treadwheel possesses a much bigger mechanical advantage due to its larger diameter. This meant that, in comparison to the construction of the ancient Egyptian pyramids, where about 50 men were needed to move ...

Exercise Treadmill Convey Motion
Exercise is a body activity that enhances or maintains physical fitness and overall health and wellness. It is performed for various reasons, to aid growth and improve strength, develop muscles and the cardiovascular system, hone athletic skills, weight loss or maintenance, improve health, or simply for enjoyment. Many individuals choose to exercise outdoors where they can congregate in groups, socialize, and improve well-being as well as mental health. In terms of health benefits, the amount of recommended exercise depends upon the goal, the type of exercise, and the age of the person. Even doing a small amount of exercise is healthier than doing none. Classification Physical exercises are generally grouped into three types, depending on the overall effect they have on the human body: * Aerobic exercise is any physical activity that uses large muscle groups and causes the body to use more oxygen than it would while resting. The goal of aerobic exercise is to increase ...

Wayne Quinton
Wayne Everett Quinton (January 4, 1921 – January 22, 2015) was a developer of over 30 biomedical devices, including the Quinton catheter. He also invented a lightweight treadmill, for cardiac stress testing - the prototype of those used in fitness centers. Quinton was raised in Rigby, Idaho. He received a degree in mechanical engineering from the University of Washington in 1959. He previously attended Ricks College (now BYU-Idaho) and Montana State University. A week after Pearl Harbor, he arrived in Seattle and began working for Boeing to work on the B-29 bomber. He was hired by the University of Washington for an Arctic Acclimatization study and subsequently as the sole member of the instrument shop. Among Quinton's inventions was a shunt with Belding Scribner and David Dillard that allowed for repeated kidney dialysis procedures on an individual, making the process one that truly extended the patient's life expectancy. He was also involved with the following inventions ...

Exercise Machine
An exercise machine is any machine used for physical exercise. These range from simple spring-like devices to computerized electromechanical devices to recirculating-stream swimming pools. Most exercise machines incorporate an ergometer. An ergometer is an apparatus for measuring the work a person exerts while exercising as used in training or cardiac stress tests or other medical tests. Resistance machines Weight machines Weight machines use gravity as the primary source of resistance, and a combination of simple machines to convey that resistance, to the person using the machine. Each of the simple machines (pulley, lever, wheel, incline) changes the mechanical advantage of the overall machine relative to the weight. Other kinds of resistance machines * Friction machines * Spring-loaded machines (such as Bowflex) * Fan-loaded machines * Fluid-loaded machines * Bullworker * Hydraulic equipment * Whole body vibration * Outdoor gym * Pneumatic exercise equipment * Treadmill En ...

Metaphor
A metaphor is a figure of speech that, for rhetorical effect, directly refers to one thing by mentioning another. It may provide (or obscure) clarity or identify hidden similarities between two different ideas. Metaphors are often compared with other types of figurative language, such as antithesis, hyperbole, metonymy, and simile. One of the most commonly cited examples of a metaphor in English literature comes from the "All the world's a stage" monologue from '' As You Like It'': All the world's a stage, And all the men and women merely players; They have their exits and their entrances And one man in his time plays many parts, His Acts being seven ages. At first, the infant... :—William Shakespeare, '' As You Like It'', 2/7 This quotation expresses a metaphor because the world is not literally a stage, and most humans are not literally actors and actresses playing roles. By asserting that the world is a stage, Shakespeare uses points of comparison between the world an ...
