STATES F'FCEQ FIRE-PROOF VESSEL.

SPECIFICATION forming part of Letters Patent No. 451,802, dated May 5, 1891.Y

Application iledJune 12, 1890. Serial No. 355,164. (No model.)

To all whom if may concern:

-Be it known that I, JOSEPH B. BRoLAsKI, of St. Louis, in the State of Missouri, have invented a new and Improved Fire-Proof Vessel, of which the following-is a full, clear, and exact description.

My invention relates to improvements in fire-proof 'vesselsg and the object of my invention is to construct a marine vessel in suoli a manner that it will be practicallytire-proof.

To this end my invention consists in a vessel with walls and ceilingsformed of metal sheets, said sheets being constructed and attached in a manner hereinafter described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a broken vertical section showing a portion of the cabin of a vessel having walls constructed in accordance with my invent-ion. Fig. 2 is a horizontal section on the line c of Fig. l. Fig. 3 is a broken detail perspective view showing the manner-of attaching the sheets to the wall-posts or stanchions. Fig. 4: is a detail view in horizontal section, showing the manner in which the sheets are attached to a post; and Fig. 5 is a detail sectional view showing the manner in which a corner is made.

In the accompanying drawings, A represents the side rail of a vessel, B the upper deck, and O the lower deck. To form the vertical partitions between the state-rooms, cabins, or other rooms of the vessel, the metal sheets D are attached to the vertical posts E. The sheets D are bent at right angles, so that the angle portion D will overlap one side of the post E, and the adjoining sheet D is attached to the opposite side of the post, so thatthe angle portion D of the said sheet will overlap the side of the post opposite the angle portion of the opposite sheet. The sheets rative.

"overlap the upper and lower parts of the partition, but will be entirely independent oi the same, thus allowing space for the expansion and contraction of the sheets D and allow' for the necessary racking movement of the vessel. NVhen the vertical partition is to be extended around a corner, an angle-plate D2 is used, said plate being adapted to overlap the rio inner sides of a corner-post E', and thus afford a protection for the same.

In carrying out my invention the parts ot' the vessel above and'below the cabins and state-rooms may be lined with the metal sheets in the same manner, and the sheets forming the vertical partitions of the various rooms arewrapped orbent around the door and window openings to protect the casings or frames from fire. The sheets used in the construction of the walls and ceilings are made, preferably, of corrugated metal; but plain metal sheets may be used, and they may be decorated in any desired manner.

In constructing the walls or vertical partitions in the manner described above, the sheets should be' curved slightly, as shown in Fig. 3, andthe resulting tension on the sheets will prevent vibration and resonance. The sheets may be also braced with met-al braces in any desired manner to give additional rigidity to the walls.

From the foregoing description it will be seen that the only exposed wood-work in the vessel will be the Iioors, the doors, and the Window and transom sashes, and that if any ot said parts should take fire, either from explosion or other causes the vertical partitions will prevent the Vrapid spread of the 'flames so that the fire may be easily controlled.

Having thus fully described my invention, I claim as new, and desire to secure by Letters Patent- IOO ings adjacent to said posts so as to overlap said metal sheet-s, substantially as described. Y

3. In a fire-proof vessel, the combination, with a corner-post E of the cabins and deckhonses above thehu1l,having plates D covering two sides thereof, of the angie-plate D2, adapted to cover the sides of the post opposite the plates D, substantially as described.
