Grinding the Wind: the Treadwheel Fan

grinding the wind the treadwheel fanI wrote about prison treadmills before. They were invented in England in 1817 by Sir William Cubit, who observed prisoners lying around in idleness and put himself to the task of “reforming offenders by teaching them habits of industry”.

Forty-four prisons in England adopted it as a form of hard labour that could also grind grain or pump water.

The system is explained in “The criminal prisons of London and scenes of Prison Life” (1862), written by Henry Mayhew & John Binny. Starting on page 299, they describe the method of “hard labour”, and the technologies used for it: the treadwheel, crank labour & the shot drill. Great reading.

Jailhouse Tech

Kevin Kelly notes an emerging category of street technology which might be called Jailhouse Tech:

“The material constraint of a prison inspire fantastic innovation and re-use of made parts. A lot of the devices made in this manner are crude weapons, but others include eating implements, tattoo instruments, music, and other tools.”

Above you see an electric cooking stove made with wire and brick. Kelly previously linked to Escape Devices, the work of photographer Marc Steinmetz. Also of note is Prisoner Inventions, a 2003 book which includes many drawings,some of them online (review 1 & 2).

Prison Treadmills

Prison Treadmill

The prison treadmill was invented in England in 1817 by Sir William Cubit, who observed prisoners lying around in idleness and put himself to the task of “reforming offenders by teaching them habits of industry.” Forty-four prisons in England adopted it as a form of hard labour that could also grind grain (although some treadwheels were only “grinding the wind“).

The punitive treadmill was then implemented in America for two long years, between 1822 and 1824, at Bellevue penitentiary outside New York. Prisoners stepped on the mill for 10 hours a day (with 20 minute breaks per hour), grinding grain, often with a large audience of jeering onlookers housed in a specially built viewing house.
