Half-section Model of Proposed Illinois State Prison Cell Houses. (See “A New Kind of Prison,” [page 7])
European prison construction is the exact opposite, in that the cells are built on the “outside” principle, that is, up against the walls of the cell house. The corridor, therefore, is in the middle of the cell house and each cell has a room to itself with a barred window to the outside air.
The “inside” cell construction in the United States has been held to have several distinct advantages, for the utility corridor, containing the various pipes, wires, etc., is an economical form of construction. The cells on the “inside” are furthermore safer in that the cell door acts as a window and the prisoner in order to escape must first go through the cell door, then through the wall of the cell house and then over the wall of the prison grounds.
Plan of Proposed Illinois State Prison. (See “A New Kind of Prison,” [page 7])
Prisons built on the “inside” plan are strongly criticised because of the limited amount of direct sunlight and direct fresh air that may be admitted to the cells. The importance of these two essentials of life is obvious. A further objection to the “inside” cell plan is that as the cells have no doors, the acts and the words of one prisoner can be readily heard or learned throughout a good part of the cell house. Supervision with either the “inside” or the “outside” plan is at present carried on through the patrolling of the corridors by a guard.
The plan evolved by Mr. Zimmerman for the cell house of the new Joliet prison seemingly overcomes the above objections in a most careful manner. It is proposed by Mr. Zimmerman to build circular shaped cell houses about 120 feet in diameter, placing the cells against the cell house wall and thus assuring direct light and air. Now comes the novelty. Instead of having an open front of steel bars, heavy glass will be fitted into the open space between these bars so as to make a completely closed room out of the cell. A full view, however, of this room is possible from a central point. This central point is a steel shaft in the center of the cell house, enclosing a circular stairway. The stairway will be as high as the highest tier of cells, and from a position half way up the circular stairway, which is completely sheathed with steel, the guard within the “conning tower” has a full view of each and every cell, at the mere turn of his head. The shaft will be arranged with narrow slots opposite the level of the eye so that it will be impossible for inmates to see the guard and impossible to know at what time they are under observation. The shaft will be bullet proof, which in case of possible mutiny assures absolute safety for the guard. An armed guard could undoubtedly from his secure position readily control a mob even though the mob be fully armed. Entrance to the shaft will be possible only through a tunnel which opens into the administration building outside the prison enclosure.
A number of these circular cell houses will be erected as indicated in the group plan here published. That this arrangement lends itself most readily to extension is evident.
Another novel feature is the possibility of classification of prisoners in different groups. Easily moving partitions will be erected as high as the upper tier of rooms and placed with sufficient frequency so that no prisoner can see from his cell into that of any other cell, an arrangement which does not interfere with the view of the guard in the “conning tower” into any room of the cell house.
