# Rotary jail

A rotary jail was an architectural design for some prisons in the Midwestern United States during the late 19th century. Cells in the jails were wedges on a platform that rotated in a carousel fashion. The surrounding of the entire level had a single opening, allowing only one cell at a time to be accessible.

## Design and patent

The rotary jail was initially designed by architect William H. Brown, and built by the Haugh, Ketcham & Co. iron foundry in the Indianapolis, Indiana neighborhood of Haughville. Their July 1881 patent had the following description:
   The object of our inventions is to produce a jail in which prisoners can be controlled without the necessity of personal contact between them and the jailer or guard ... it consists, first, of a circular cell structure of considerable size (inside the usual prison building) divided into several cells capable of being rotated, surrounded by a grating in close proximity thereto, which has only such number of openings (usually one) as is necessary for the convenient handling of prisoners.

## Features

The pie-shaped cells rotated around a core having a sanitary plumbing system, which was considered an unusual luxury at that time. The cell block could be rotated by a single man hand-rotating a crank. It was connected to gears beneath the structure which rotated the entire cell block. The structure was supported by a ball bearing surface to allow for smooth rotation.

## Condemned

The jails encountered problems almost immediately with inmates' limbs being crushed or interfering with the cellblock's rotation. Most of the jails had to be welded in a fixed position and refitted with individual cell accesses after only a few years. All of them, except for one, were condemned by June 22, 1939. The Pottawattamie County Jail in Council Bluffs, Iowa, remained in use until December 1969. The rotary mechanism was disabled as late as 1960, following an incident where an inmate died of natural causes but the body could not be retrieved for two days due to a malfunction in the mechanism.
The last rotary jail with an operating rotary mechanism in existence is in Crawfordsville, Indiana. As per the original design, the jail could handle 16 prisoners and the third floor contained three cells for ill inmates to keep them separate from the remainder of the population. This jail had its rotary mechanism disabled around the late 1930s and the structure was condemned in 1967 and closed fully as a jail in 1973.

## Legacy

The last remaining mechanically operating rotary jail is the Montgomery County Jail and Sheriff's Residence in Crawfordsville, Indiana, which opened in 1882 and housed prisoners for over half a century. Following its closure in 1973, the Montgomery County Cultural Foundation rescued the facility two years later and established the Old Jail Museum. Having previously had its rotary mechanism welded shut, this was unwelded around 1975 so that the jail could rotate again.
Following a generous bequest from one of its founders in 1985, the foundation undertook extensive renovations, although restoration of the rotary cell block was not completed until 1996. The former sheriff's home is used by the local community to house receptions and workshops.
As of 2002, only two others are known to have survived: one in Council Bluffs, Iowa and one in Gallatin, Missouri.

## Locations

Sources vary as to how many rotary jails had been built. One source reports that 17 rotary jails were contracted for construction but only 12 were ever completed, while others say 17–18 were actually constructed (based on jail-construction company records) whereas another claims as few as seven were ever built.
