The main objects of this invention are:

First, to provide a life raft or fioat which comprises a buoyant body having sealed water-tight compartments for the storage of water, food or equipment.

Second, to provide a structure of this character in which these compartments are provided with closures on both horizontal sides thereof so that they are accessible with the raft body either side up.

Third, to provide a lift raft or float in which the body portion is formed of metal and comprises a plurality of independent water-tight compartments providing a large degree of buoyancy in proportion to the size of the structure and substantial buoyancy even though several of the compartments may be punctured as by machine gun re.

Fourth, to provide a life raft having these advantages which is very strong and rigid and capable of withstanding the shocks incident to use, such as dropping the raft a considerable distance as from a vessel.

Fifth, to provide a structure of this character in which there are no protuberances or projections likely to injure the occupants or to be broken off in use or handling.

Objects pertaining to details and economies of the invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of the invention is clearly illustrated in the accompanying drawing, in which:

Fig. 9 is an enlarged transverse section on line 9-9 of Fig. 8.

Fig. 10 is an enlarged fragmentary View of one of the metal body sections of the embodiment shown in Fig. 8.

Fig. 11 is a diagrammatic view illustrating the nesting of a plurality of rafts.

In the embodiment of the invention illustrated in Figs. 1 to 7, inclusive, the raft or float body is octagonal in shape while that shown in Fig. 8 is of elliptical shape. Each shape has certain advantages in structure and manufacture which will be brought out in the description.

The embodiment of the invention shown in Figs. 1 to 7 comprises side members I, I, end members `2, 2 and corner members 3. Each body member is formed of a plurality of tubular sheet metal or

pipe sections

4 and 5, the sections being brought end to end rand Welded to each other and to the transverse partition elements `6, the

weld being indicated at 1, Fig. 3. These trans- Verse partition members 6 constitute reinforcing members and bulkheads. It will be noted that the side and end corner members have mitered ends which are likewise welded together and welded to the flat partition members 8 which constitute reinforcing members and bulkheads. The rframe-like body is thus essentially tubular in cross section and is provided with a plurality of spaced bulkheads which result in a plurality of water-tight compartments.

Each compartment is preferably provided with a pipe fitting 9 welded at I0 with the outer end of the fitting substantially flush or projecting but little from the surface of the body as shown in Fig. 4. These fittings have removable plugs Ii which may be removed for testing each compartment and also for the internal coating of the compartment with a rustproof coating or finish. As shown in Fig. 3, the sections 5 are essentially the same as the sections 4 except that the sections 5 have openings I2 preferably in both horizontal sides thereof, the openings receiving the cupped closure housings I3, the outer edges of which are welded as at I 4 to the edges of the opening I2 forming a shield and rigid joint at this point. l

The closure I5 which is provided with a suitable gasket is mounted on a suitable arm i6 pivoted at` I'IV on the ear I8 and detachably secured as by means of the pin I9 to the opposed ears '26.

ingly engaging within the end/of one sectionand the adjoining end of an adjacent section, the adjacent edges of the sections being welded to each other and to the flanges of said bulkheads, lthe side and end corner body members having mitered joints, and fiat bulkheads disposed at such mitered joints, the adjacent edges of the body memu bers at said mitered joints being welded to each other and to said last named bulkheads, such assembly providing a plurality of water-tight compartments.

2. In a life raft or float, the combination of a frame-like buoyant body comprising side and end corner body members, each body member comprising a plurality of tubular sheet metal sections disposed end to end, bulkheads between the sections, the bulkheads having a flange telescopingly engaging within the end of one section and the adjoining end of an adjacent section, the adjacent edges of the sections being welded to each other and to the anges of said bulkheads, the side and end corner body members having mitered joints, and bulkheads disposed at such mitered joints, the adjacent edges of the body members at said mitered joints being welded to each other and to said last named bulkheads, such assembly providing a plurality of water-tight compartments.

3. In a life raft or float, the combination of a frame-like buoyant body comprising a plurality of tubular metal sections disposed end to end, bulkheads at the joints of the sections, the adjacent edges of the sections being welded to each other and to said bulkheads, the bulkheads providing a plurality of water-tight compartments, a decking provided with a suspending net, attaching rings for said net, and horizontally disposed elongated clips welded at their opposite ends to said sections, said clips providing vertically disposed openings for receiving said rings, said net including a cable member disposed along the top edge o the net and extending horizontally through said rings.

4. In a life raft or float, the combination of a frame-like buoyant body comprising a plurality of tubular metal sections disposed end to end, bulkheads between the sections, the adjacent edges of the sections being connected to each other and to said bulkheads, the bulkheads providing a plurality of water-tight compartments, and a rustproof covering for said body, said covering comprising successively from said body outwardly, a coat of rust resisting paint, a coat of lacquer, a coat of rubber cement and a wrapping of canvas, said canvas being wrapped spirally longitudinally of the body and across the abutting ends of the tubular metal sections of the body.
