TRUNK.

LPESIFICA'IION forming part of Letters Patent No. 291*,607, dated January 8, 1884.

Application filed July 21, 1853. (No model.)

To (LZZ 107mm it 17mg concern:

Be it known. that I, AUGUST Knonsine, of the city of Berlin, Prussia, Germany, have invented certainnew and useful Improvements in Trunks for Life-Saving at Sea, of which the following is afull, clear, and exact description.

The object of my invention is to provide a new and improved trunk, which can be used as a float to save lives at sea.

The invention consists of a water-proof trunk providedwith buoyant wings for increasing its buoyancy and stability, with eyes or rings for fastening ropes or holding signal-staffs, and packing strips in the joints, and with angle- I 5 plates overlapping the cover and secured to the sides and ends of the bottom section of the trunk, all as hereinafter fully described.

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

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

Figure l is an end view of two of my improved trunks, showing them united by ropes to form a raft. Fig. 2 is a plan View of the 2 5 same. Fig. 3 is a detail sectional elevation of a part of the same.

The trunk is made of very light wood or cork, and is provided with a covering which makes it absolutely waterproof, or itis treated in such a manner that it will be waterproof. The trunk is composed of top and bottom sections, A A provided with lap-joints, between which rubber packing-strips a and bare placed, to prevent the water from leaking into the trunk. An gle-plates B are placed on the sides of the bottom section of the trunk and over-j lap the top sections or cover, and are held in place by screws 0, passed through the lower parts of the'angle-plates in the sides ;of the bottom trunk-section. The sides of the trunk have an upward incline from the bottom, whereby abroad base is given to it,which enables it to ride better and safer on the water. A wing, D, made of cork or other very buoyant materm], is pivoted to the bottom of the trunk along each longitudinal edge, which wings can be folded under the bottom of the trunk when the same is not in actual service as a lifesaving device. .The wings D can easily be swung out to project from the trunk. The trunk is provided on its top with a series of loops or eyes,

I E, for fasteninga rope, F, to which a life-pie server, &c., can be fastened, or two or more trunks can be united by means of the ropes F, to form a raft. Rings or eyes G are provided on one or both ends of the trunk, for receiving a staff, H, on which a flag, lantern, or other signal can be fastened.

A tin box containing rockets, signals, compass, &c., can be fastened to the trunk.

A trunk of this kind can carry from five hundred to eight hundred pounds, according to the size. The trunk must be closed absolutely water-tight, as its buoyancy will be destroyed to a great extent if water enters it. The interior of the trunk can be divided into suitable compartments in the usual manner.

The wings D materially increase the buoy; an cc of the trunk, and give the trunk a wider base, and increase the stability of the trunk in the water.

I do not abandon or dedicate to the public any patentable feature set forth herein and not hereinafter claimed, but reserve the right to claim the same either in a reissue of any patent that may be granted upon this application or in other applications for Letters Pat tent that I may make.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is-

l. Awater-proof trunk provided withbuoy; ant wings for the purpose of increasing its stability and buoyancy, substantially as herein shown and described.

2. A water-proof trunk provided with buoyant wings hinged to the trunk and adapted to fold under the same or project from, the same, substantially as herein shown and described. 3. A water-proof trunk having buoyant wings hinged thereto, and the eyes E, secured to its cover, substantially as herein shown and described, whereby provision is made for attachment of a life-preserver or connecting two or more trunks together, as set forth.

4. A water-proof trunk having buoyant wings hinged thereto, and eyes G, secured to the end of the trunk, substantially as herein shown and described, whereby provision is made for securing a signalstafi' to the trunk, mg as set forth.

5. The combination, with a water proof trunk formed of (0p and bottom sections, A i my own I have hereunto signed my name in A, and having inclined sides, of packing- I the presence of two subscribing witnesses.

strips a b placed in the joints the an 'le-plates B, overlapping the top section, and s ecured to AUGUST KROESING' 5 the bottom section by the screw 0, substan- \Vitnesses:

tially as herein shown and described. B. ROI,

In testimony that I claim the foregoing as G. H. SMITH.
