Treadle
A treadle (from oe, tredan, "to tread") is a mechanism operated with a pedal for converting reciprocating motion into rotating motion. Along with cranks, treadmills, and treadwheels, treadles allow human and animal machine power in the absence of electricity. Before the widespread availability of electric power, treadles were widely used to power a range of machines. They may still be used as a matter of preference or in environments where electric power is not available. Operation and uses A treadle is operated by pressing down on its pedal with one or both feet, causing a rocking motion. This movement can then be stored as rotational motion via a crankshaft driving a flywheel. Alternatively, energy can be stored in a spring as in the pole lathe. Treadles were once used extensively to power most machines including lathes, rotating or reciprocating saws, spinning wheels, looms, and sewing machines. The last use was popularized by Elias Howe and Isaac Singer in the eponym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Treadle Pump
A treadle pump is a human-powered suction pump that sits on top of a well and is used for irrigation. It is designed to lift water from a depth of seven metres or less. The pumping is activated by stepping up and down on a treadle, which are levers, which drive pistons, creating cylinder suction that draws groundwater to the surface. Application Treadle pumps free farmers from dependence on rain-fed irrigation and helps farmers maximize return on their small plots of land. The treadle pump can do most of the work of a motorized pump, but costs considerably less. Pump prices including installation range between US$20 and $100. Because it needs no fossil fuel (it is driven by the operator's body weight and leg muscles), it can also cost less (50%) to operate than a motorized pump. It can lift five to seven cubic metres of water per hour from wells and boreholes up to seven metres deep and can also be used to draw water from lakes and rivers. Many treadle pumps are manufactured locall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Treadle Bicycle
A treadle bicycle is a bicycle powered by a treadle instead of the more common crank. Treadles were one of the mechanisms inventors tried in order to position the pedals away from the drive wheel hub before the development of the bicycle chain or instead of it. Treadles have also been used to drive tricycles and quadracycles. History Treadles were used before the advent of highwheelers on Thomas McCall's velocipede, on highwheelers themselves in an attempt to address safety issues, on alternative configurations of highwheelers, and on the first device called a safety bicycle by British engineer Henry J. Lawson in 1876. Some inventors even combined treadles and chains on the same bicycle.

Spinning Wheel
A spinning wheel is a device for spinning thread or yarn from fibres. It was fundamental to the cotton textile industry prior to the Industrial Revolution. It laid the foundations for later machinery such as the spinning jenny and spinning frame, which displaced the spinning wheel during the Industrial Revolution. Function The basic spinning of yarn involves taking a clump of fibres and teasing a bit of them out, then twisting it into a basic string shape. The spinner continues pulling and twisting to make it longer and longer, and to control the thickness. Thousands of years ago, people began doing this onto a stick, called a spindle, which was a very lengthy process. The actual wheel part of a spinning wheel does not take the place of the spindle, instead it automates the twisting process, allowing one to "twist" the thread without having to constantly do so manually, and also the size of the wheel lets one more finely control the amount of twist. The thread still ends up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Pedal
The pedal is the part of a bicycle that the rider pushes with their foot to propel the vehicle. It provides the connection between the cyclist's foot or shoe and the crank allowing the leg to turn the bottom bracket spindle and propel the bicycle's wheels. A pedal usually consists of a spindle that threads into the end of the crank, and a body on which the foot rest is attached, that is free to rotate on bearings with respect to the spindle. Pedals were initially attached to cranks connecting directly to the driven (usually front) wheel. The safety bicycle, as it is known today, came into being when the pedals were attached to a crank driving a sprocket that transmitted power to the driven wheel by means of a roller chain. Types Just as bicycles come in many varieties, there are different types of pedals to support different types of cycling. Flat and platform Traditionally, platform pedals were pedals with a relatively large flat area for the foot to rest on, in contrast t ...

Crank (mechanism)
A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft, or a separate arm or disk attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod (conrod). The term often refers to a human-powered crank which is used to manually turn an axle, as in a bicycle crankset or a brace and bit drill. In this case a person's arm or leg serves as the connecting rod, applying reciprocating force to the crank. There is usually a bar perpendicular to the other end of the arm, often with a freely rotatable handle or pedal attached. Examples Familiar examples include: Hand-powered cranks * Spinning Wheel * Mechanical pencil sharpener * Fishing reel and other reels for cables, wires, ropes, etc. *Starting ...

Loom
A loom is a device used to weave cloth and tapestry. The basic purpose of any loom is to hold the warp threads under tension to facilitate the interweaving of the weft threads. The precise shape of the loom and its mechanics may vary, but the basic function is the same. Etymology and usage The word "loom" derives from the Old English ''geloma'', formed from ''ge-'' (perfective prefix) and ''loma'', a root of unknown origin; the whole word ''geloma'' meant a utensil, tool, or machine of any kind. In 1404 "lome" was used to mean a machine to enable weaving thread into cloth. By 1838 "loom" had gained the additional meaning of a machine for interlacing thread. Weaving Weaving is done by intersecting the longitudinal threads, the warp, i.e. "that which is thrown across", with the transverse threads, the weft, i.e. "that which is woven". The major components of the loom are the warp beam, heddles, harnesses or shafts (as few as two, four is common, sixteen not unheard of), s ...

Historical Re-enactors
Historical reenactment (or re-enactment) is an educational or entertainment activity in which mainly amateur hobbyists and history enthusiasts dress in historic uniforms or costumes and follow a plan to recreate aspects of a historical event or period. This may be as narrow as a specific moment from a battle, such as the reenactment of Pickett's Charge presented during the Great Reunion of 1913, or as broad as an entire period, such as Regency reenactment. While historical reenactors are generally amateurs, some participants are members of armed forces or historians. The participants, called reenactors, often do research on the equipment, uniform, and other gear they will carry or use. Reenactors buy the apparel or items they need from specialty stores or make items themselves. Historical reenactments cover a wide span of history, from the Roman empire to the major world wars and the Korean War of the 20th century. History Activities related to "reenactment" have a long hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Singer Corporation
Singer Corporation is an American manufacturer of consumer sewing machines, first established as I. M. Singer & Co. in 1851 by Isaac M. Singer with New York lawyer Edward C. Clark. Best known for its sewing machines, it was renamed Singer Manufacturing Company in 1865, then the Singer Company in 1963. It is based in La Vergne, Tennessee, near Nashville. Its first large factory for mass production was built in 1863 in Elizabeth, New Jersey. History Singer's original design was the first practical sewing machine for general domestic use. It incorporated the basic eye-pointed needle and lock stitch, developed by Elias Howe, who won a patent-infringement suit against Singer in 1854. Singer obtained in August 1851 for an improved sewing machine that included a circular feed wheel, thread controller, and power transmitted by gear wheels and shafting. Singer consolidated enough patents in the field to enable him to engage in mass production, and by 1860 his company was the la ...

Isaac Singer
Isaac Merritt Singer (October 27, 1811 – July 23, 1875) was an American inventor, actor, and businessman. He made important improvements in the design of the sewing machine and was the founder of what became one of the first American multi-national businesses, the Singer Sewing Machine Company. Many others, including Walter Hunt and Elias Howe, had patented sewing machines before Singer, but his success was based on the practicality of his machine, the ease with which it could be adapted to home use and its availability on an installments payment basis. Singer died in 1875, dividing his $13 million fortune unequally among 20 of his living children by his wives and various mistresses, although one son, who had supported his mother in her divorce case against Singer, received only $500. Altogether he fathered 26 children. Early life Isaac Merritt Singer was born on October 27, 1811, in Pittstown, Schaghticoke, New York. He was the youngest of eight children born to a Germ ...

Elias Howe
Elias Howe Jr. (; July 9, 1819October 3, 1867) was an American inventor best known for his creation of the modern lockstitch sewing machine. Early life Elias Howe Jr. was born on July 9, 1819, to Dr. Elias Howe Sr. and Polly (Bemis) Howe in Spencer, Massachusetts. Howe spent his childhood and early adult years in Massachusetts, where he apprenticed in a textile factory in Lowell beginning in 1835. After mill closings due to the Panic of 1837, he moved to Cambridge, Massachusetts, to work as a mechanic with carding machinery, apprenticing along with his cousin Nathaniel P. Banks. In the beginning of 1838, he apprenticed in the shop of Ari Davis, a master mechanic in Cambridge who specialized in the manufacture and repair of chronometers and other precision instruments. It was in the employ of Davis that Howe seized upon the idea of the sewing machine. He married Elizabeth Jennings Ames, daughter of Simon Ames and Jane B. Ames, on March 3, 1841, in Cambridge.Edmund Rice (1638) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
