Abstract

Abstract A portable jail cell which can be transported as a unit and installed in a jail or designated building. A windowless structure which has a foraminous metal screen door for light and air, is of ribbed sheet metal panels except for the floor. The floor is of cast concrete provided with channels on which to set and weld a unit cell. Sheet metal bunks which are welded inside the cell create a solid one piece unit. At one corner is an angled wall portion connecting contiguous side walls, and on the inner side of which are the toilet and wash bowl and on the outer side are suitable plumbing fixtures. This enables two cells to be placed side by side with adjacent angled wall portions to provide convenient access chambers and dispose the plumbing for the two cells in conveniently accessible location. The sheet metal for the wall panels is not less than one-eighth inch in thickness to militate against manual cutting.
