SAFETY DEVICE FOR SUBMARINES.

Application filed March 8, 1928. Serial No. 260,222.

This invention relates to safety devices for submarines.

Objects of this invention are to provide a safety device for submarines which is so constructed and which cooperates with a peculiar construction of submarine in a novel manner to permit the egress of the occupants of the submarine even in the event that the submarine rests upon the bottom and is disabled.

More specifically, this invention relates to lneans used in connection with submarines, which is so formed that it may be attached to the submarine and thereafter a man-hole cover may be removed from the submarine within the device to thus permit the occupants of the submarine to pass outwardly such device extending about the water level.

Further objects are to provide a novel type of device for attachment to submarines which is formed of tubular, universally ointed sections, with the oints formed in a. water-tight manner, and to provide the submarine with a plurality of means for receiving the tubular member at several diflerent positions, so that one at least of the positions is always accessible, irrespective of the position in which the submarine rests. 1

An embodiment of the invention is shown in the accompanying drawings in which:

Figure 1 is a fragmentary view of a submarine showing the device attached, such device being partly in section;

Figure 2 is an enlarged view of one of the joints between the sections of the device, such view being partly in section;

Figure 3 is a view in section showing the manner of attaching the device to the submarine.

Referring to the drawin s, it will be seen that a submarine 1 has a plurality of apertures 2 formed at spaced positions through its side walls. These apertures are so positioned and are of such number that access may be had to the submarine, irrespective of the posi tion at which it rests upon the bot-tom. Preferably, a flanged member 3 is secured to the body of the submarine at the apertures and has a man-hole 4t therethrough. This manhole is covered by means of a plate or man hole cover 5 which is bolted to the member 3 and which is provided with a gasket 6. It is to be noted particularly from reference to Figure 3 that the member 3 extends outwardly beyond the man-hole cover and is provided with threaded apertures for the reception of bolts 7.

These bolts areadapted to be passed through a flange 8 carried by the lower section 9 of the attachment.

The attachment or tubular member con-- sists of a plurality of sections 9, 10. and 11, as indicated. Obviously, more sections can be added as required. Each of the sections are oined by means of a universal joint, for nstance, as shown in Figure 2, and these oints are water-tight. One mode of formmg the joints may consist in forming the upper end of a section in a spherical shape, as indicated at 12 in Figure 2, and forming the lower end of theadjacent section spherical, as indicated at 13 in Figure 52, and of such size as to lit over the portion 12 of the lower section. The portion 13 is provided with an outwardly projecting flange 14: to which is removably bolted a packing receiving member 15. Between the members 1% and 15, a packing 16 is positioned. Preferably, the opposed faces which contact with the packing are formed bevelled, as indicated by the ref erence character 17.

In this manner, a universal water-tight joint is formed between successive sections and the construction enables the attachment to be applied to the submarine although obstructions occur in the bottom upon which the submarine rests. In other words, the jointed, tubular member may be bent, as re quired, to facilitate its positioning on the sunken submarine. The articulation of the sections permits this ready shaping of the es cape or tubular member to the exact requirements.

The upper section 11 may be provided with a pair of eye bolts 18 adapted to receive stays or cables 19, so that it may be held from other boats or floats.

in using the device, a diver is sent down and the flange 8 of the lower section is bolted to one of the accessible members 3. There after, water is pumped out of the tubular, articulated casing and thereafter the man hole cover 5 is removed and the occupants of the submarine may be lifted upwardly through the casing by any suitable tackle.

It is obvious from the description given above that the device affords a ready exit for the occupants of a sunken submarine and is of such construction that it may be readily entered by a diver and may be easily posi tioned.

it is to'be distinctly understood that the lowest section may have a jointed or articuios lated lower endprovided with a flange corresponding to'the flange 8, without departing from the spirit of this invention.

Although the invention has been described in consider-able detail, such-description is: intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to-be deter mined as claimed.

Weclaim:

The co1nb ination 015a submarine having a plurality of spaced apertures,flangedmenibel's surrounding said apertures and having a unan hole 'therethrough, man hole eover-s reinovably attached to said flanged members, said flanged members having threaded apela'v hereby said tubular .in'einber ma-y be attached to any of said flanged members and them'an hle cover may be subsequently reanoved, said tubular member being formed of a. plurality of sections having universal,

WaterQtight-joints between the sections.
