Specification of Letters Patent No. 26,500, dated Decemberj1j859. i i

To all whom it may concern:

Be it known that I, ENooH; JACOBS, of the city of Cincinnati,` in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Jails or Prisons; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, made to form a part of this specication. j

My invention relates 1st to the construction of jails or prisons, of chilled-rolled wrought-iron plates, secured together in edges of the plates at corners.

such manner that the walls, partitions, and Hoors of said structure may be substantial, strong and durable, and most eii'ectually prevent the escape of persons confined therein, and at the same time `afford `all necessary facilities for plumbing, light, ventilation, ingress and egress. 2d to a special provision for securing the edges of said plates. 3d to a device for more perfectly securing the doors, as hereinafter specified and represented. i j

Of the accompanying drawings, Figure 1 represents a ground plan of the jail or prison surrounded by a wall of masonry. Fig. 2 shows in perspective an external view of the jail the doors of which are provided With the securing keeper. Fig. 3 `is a perspective view showing of the base floor, and the arrangement of the barred ventilator. Fig. 4.'is a sectional view taken through the red lines (m i?, showing the manner of `overlaying an securing the Fig. 5, is a sectional view taken through the red line (y y) showing the manner of securing the abutted edges of the plates. Fig. 6, is a sectional view of the upper floor or top of the jail. Fig. 7, is a sectional bottom view of the base floor.

(A) are chill-rolled wrought plates of which the jail or prison is constructed. Their edges are abutted as fully shown in Fig. 5, thus presenting a `smooth surface upon the inside, and preventing the insertion of wedges or other devices by means of` Which the plates (A) might be separated,

`to allow the sawing or cutting of the rivets.`

(e) `are strips ofthe isame `materialiand;f thickness as i the plates (A), `overlayingthe joints or seams formedbyfthe abutted: edges 1 55 of the plates; These stripse) @are iirinly riveted to said plates, on eaclisideofthe:
