Montgomery County Jail Building

In 1881, architect William H. Brown answered the human incarceration problem with an engineering solution by designing a revolutionary new jail concept in housing criminals. Brown teamed up with Benjamin F. Haugh of Haugh, Ketcham & Co. iron foundry in Indianapolis, Indiana to build this modern masterpiece.

What was this work of genius, you may ask? A rotary jail.

Hmm… Sounds a bit odd. But whenever someone comes up with a new solution or new take on an old problem, it can seem odd. Let’s find out how this one stacks up on the oddity chart.

Brown’s idea was to have a revolving cell block. There were generally eight wedge-shaped cells per floor with a single exit shared by all the cells on that floor. This way only one cell could be accessed at a time, providing more security and fewer guards required to oversee the prisoners.

Cell Platform

The patent for this new style of jail had this 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.”


Cell Door Partially Open & Cell Door Open

Sounds like the perfect social-distancing facility between guards and inmates. But one cell would often house more than one prisoner. No social distancing there.

The greased mechanism
sat on a ball bearing surface that was so well built a single man could work the crank to spin the entire block.

Rotating Crank Mechanism

In the late 1800s, several of these rotary jails were built across the American Midwest. The first was constructed in Crawfordsville, Indiana in 1882. Five others were soon built in the Midwest. In total, eighteen of these bad boys were erected at a cost of $30,000 each.

The rotary jail boasted an indoor, sanitary plumbing system, a luxury most regular people didn’t have yet. Prisoners received three meals a day, a hot bath, and their clothes laundered. A pretty sweet deal.

Very quickly the pitfalls and safety hazards to this style of construction became evident. First, the jails often held mostly individuals too inebriated to walk. They might pass out in their cell with an arm or leg through the bars. Then when the cell block was rotated, arms and legs were injured ... or worse.

Another hazard was what to do in case of a fire. A guard would need to stay behind to turn the crank handle to let the prisoners out one wedge-shaped cell at a time. Who was going to watch these freed prisoners with the reduced manpower? And what if the guard was too afraid for his own life to stay inside a burning building. Not good. A set up for failure.

Double-Tiered Cell Block

Due to the safety hazards, most of the rotary jails had their mechanisms welded into a stationary position and doors made for each cell within a few years. Nearly all of these jails were decommissioned by 1939. The Pottawattamie County jail in Council Bluffs, Iowa was the last of these jails in service. It shut down in December of 1969. It’s rotating mechanism was still in use up to 1960.

The Montgomery County rotary jail in Crawfordsville, Indiana is the only one of these jails still able to rotate. However, no prisoners are housed there as it is now a museum. This would be so much fun to visit.

I would give Brown high marks for ingenuity, creativity, and out of the box thinking. But very-low marks for safety considerations before construction and cost savings for their clients. I wonder if any of the towns, which had these jails built, recouped the money they were supposed to save by paying fewer guards.
