Treadmills Home Use for punishment usually rotate around a horizontal axis, requiring the user to step upwards, like walking up a never-ending staircase. Those punished are outside the wheel. Small similar horizontal-axis treadmills but with a single occupant inside are familiar toys for small pet animals such as hamsters. This type of treadmill is often called a treadwheel.
Treadmills Buying Guide were used in prisons in Britain from 1818 and until the second half of the 19th century; they were like twenty-foot long paddle wheels with twenty-four steps around a six-foot cylinder. Several prisoners stood side-by-side on a wheel, and had to work six or more hours a day, effectively climbing 5,000 to 14,000 vertical feet. While the purpose was mainly punitive, the mill could grind grain, pump water, or ventilate.
Treadmills as power sources originated in antiquity. These ancient machines came in three major designs. The first was to have a horizontal bar jutting out of a vertical shaft. It rotated around a vertical axis, driven by an ox or other animal walking in a circle pushing the bar. Even humans were used to power them. The second design was a vertical wheel that was powered through climbing in place instead of walking in circles. This is similar to what we know today as the hamster wheel. The third design also required climbing but used a sloped, moving platform instead.
Treadmills as muscle powered engines originated roughly 4,000 years ago.Their primary use was to lift buckets of water. This same technology was later adapted to create rotary grain mills and the treadwheel crane. It was also used to pump water and power dough-kneading machines and bellows.
