TREADMILL
The fact that treadmills were originally nineteenth century instruments of penal torture cropped up on HH this week. Depending on your views of exercise, you might think not much has changed. But how did we get from an instrument of prison punishment to an instrument of PT punishment training equipment?
Well, as we’ve blogged before over on the HH website (which is in the process of getting a lick of paint at the minute—apologies for any glitches in the meantime) the original treadmill was the work of English engineer William Cubitt.
Cubitt was born in Norfolk in 1785. The son of a local miller, he grew up in an agricultural community and dedicated much of his early life—and his unending enthusiasm for design and invention—to producing machinery aimed at easing the tough manual labour he had grown up around. In fact, Cubitt’s long list of inventions included everything from a new design for an agricultural thresher to a set of self-regulating windmill sails. Boons, the both of them.
In later life, Cubitt moved to London and applied his engineering know-how to much larger projects like canals, bridges, railways and docks; the Oxford Canal, the old coal-loading docks at the mouth of the river Tees, and part of the London to Brighton railway line are all examples of his work.
For all that, he was knighted by Queen Victoria in 1851. But out of a lifetime of innovation and accomplishment, one of Cubitt’s inventions stands out above all others: in 1818, he invented the treadmill.
If legend is to be believed, supposedly Cubitt one day noticed the prisoners in one of London’s jails merely idling away their time in the prison yard. Sensing a wasted opportunity, he conceived of a device that would not only stir them from their lassitude and allow them to pass their time in prison more actively, but could harness this activity to provide a useful service—albeit an arduous and unpleasant one.
The design he came up with involved an enormous cylinder, surrounded by a series of loops or belts, each fitted at regular intervals with steps or rungs. Pushing down on the first step with your foot would move the belt around the cylinder, and bring another step around to take its place, essentially forming a never-ending staircase. In a gruelling eight-hour shift on one of Cubitt’s devices, a prisoner stepping in this manner would climb the equivalent of more than 7,000ft.
This huge man-powered mill could then be adapted or connected up to some other piece of machinery, harnessing the men’s labour to do anything from grinding grain to crushing rocks to produce grit for the construction industry.
Cubitt initially referred to his invention as the “tread-wheel”, but in a description published in 1822 it is referred to as “the tread-mill invented by Mr William Cubitt ... for the employment of prisoners”. And this—a hard-labour punishment in nineteenth century jails—was the first recorded treadmill in the English language.
Cubitt’s treadmill remained in use in English prisons right through to the turn of the century, when prison reform and the increasing industrialization of society made the work the prisoners were performing a thing of the past. As they disappeared, so too did the word treadmill itself, until it was rescued from obscurity in the 1950s—during the post-war vogue for fitness and exercise—and applied to a piece of gym equipment that used a similarly unending, foot-powered, rotating belt.
Although which of the two provides the least pleasant experience is up to you to decide...
