' Submarine and Ship Safety Apparatus,- of

which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a submarine and ship safety apparatus, and has for its object the production of a simple and efficient means for permitting a submarine to be easily located should the sameaccidentally sm production of a simple and efficient-means for permitting the raising of a sunken submarine, and also permitting the connection with the occupants of the submerged submarine.

With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

Fig. 12 is a side elevation partly in section showing the construction of a float which may be submerged and attached to the hoisting cable for the purpose of raising the submarine after the same has been accidentally submerged or sunk.

Fig. 13 is a front elevation of the inverted grappling hook.

Fig. 1 1 is a bottom plan view of the applmg hook. gr

Fig. 15 is a top plan view of the upper end of the inverted grappling hook. FFig. 16 is a detail view of parts shown in *By referring to the drawings it will be seen" that 1 designates the submarine which is provide'dwith a compartment 2' near the top portion thereof, and adjacent the upper deck and this compartment 2 is provided with a cradle portion 3' upon the upper deck thereof. A float 4 is adapted to be seated upon the cradle portion 3, and this float 4 is preferably of an air tight structure having a cork base 5 secured to the bottom of the float to cause the float to still retain its buoyancy should the casing of the float become damaged or otherwise injured. The float 4 carries a depending eye 6 to which is secured a cable 7.

The upper deck of the submarine 1 is provided with an opening 8, and a hanger frame 9 is suspended from the bottom portion of the deck of the submarine by being journaled upon the journal pins 10. This hanger frame 9 is provided with a hopper portion 11 which is provided with a substantially conical shaped socket through A Windlass or drum 12 is carried by the lower end of the frame 9 and a crank handle 13 is adapted to operate the Windlass or drum 12 for winding the cable thereon.

It should be understood that the cable -7 may be wound upon the drum or Windlass 12 in such a manner as to permit the cable to readily unwind should the submarine accidentally sink. It should be understood, of course, that as the submarine sinks, the

buoyancy of the float 4 will cause the cable '7 to unwind from the Windlass 12, and the quired to equalize pressure on both sides of float, and allow it to rise by ,its buoyancy. A. door 15 is carried by the compartment 2 to permit access to be had within the compartment 2 when so desired.

A. drain pipe or valve 16 may also be connected to the bottom portion of the compartment 2 for the purpose of draining the same when so desired.

For the purpose of permitting the submarine to be raised after the same has once been submerged through accident or other inadvertent cause, a grapple hook 17 is employed, which grapple hook comprises a pair of jaws 18 provided with concave adjoining faces 19 for embracing the cable 7.

The jaws of the grapple hook 17 terminate in outwardly projecting cars 22 at the upper ends thereof, which ears are adapted to fit under the shoulder portions23 formed around the lower end'of the hopper 11. The grapple hook 17" is provided with a pulley 24 around which the hoisting cable 25 passes, and the opposite end of the hoisting cable 25 is connected to a suitable lifting means carried by the hoisting ship 26.

It should be understood that the grapple hook 17 is adapted to slide by gravity on the cable 7. When the grapple 17 reaches the hopper 11, the ears 22 fold and the grapple 17 passes through the hopper 11 into compartment 2, after which the action of gravity causes the projecting ears 22 to engage the shoulders 23 of the hopper 11 and constitutes an eflicient means for connecting the hoisting cable 25 to the hopper- 11 for the purpose of raising the submarine.

In Figs. 4 and 12 there is shown an em bodiment of the invention wherein the submarine 27 is provided with the usual cradle 28 upon the upper deck thereof for receiving the float 29. The float 29 is provided esa-see with a cork base 30 similar to the structure illustrated and described with reference to Fig. 5 of the drawings. A hatchway 31 is carried by the float 29 to permit access to be had to the interior of the float when so desired, and a telephone 32 is placed within the float 29, the wire 33 of the telephone passing down through the cable 34, which cable 34 is connected to the eye 35 of the bolt 36.

The cable 34 is connected to a Windlass 37, and the telephone wire 33 is provided with the usual electrical connections 38 for permitting the telephone 39 to communicate with the telephone 32 within the float 29.

From the foregoing description it will be seen that by means of the present device, communication may be easily had between the float 29 and the interior of the submarine, since the telephone 39 is placed upon the outer wall of the Windlass-carrying compartment 40.

As shown in Fig. 12 an embodiment of the invention is provided wherein a float 41 is used having a channel 45 formed centrally therethrough for the purpose of permitting the hoisting cable 43 and grapple hook 17 to pass therethrough. A grapple hook 17 is carried by the cable 43, and one or more inverted grapple hooks 45 are also carried thereby. The grapple hook 45 is adapted to limit the upward movement of the float 41, and the grapple hook 17 is adapted to engage the hopper 11 carried by the frame 9.

The float 41 is adapted to be filled with water for the purpose of submerging the same to the depth of the submarine, and after the float 41 is connected to the grapple hook 45, air is forced through the air hose 46 for driving the water out from the float 41 by discharging the water through the valve 47.

It will, therefore, be seen that by attaching the float 41 and relieving the water from the float 41, the float will regain its buoyancy and cause the submarine to be raised.

It, of course, should be understood that the hoisting cable 43 may be attached to the float cable 7 in asimilar manner such as that illustrated in Fig. 1 of the drawing.

By carefully considering the drawings, especially Fig. 2, it will be seen that the shaft which supports the drum 12 is provided with a sprocket wheel 50 over which a sprocket chain 52 passes. This sprocket chain 52 passes over a sprocket wheel carried by the shaft 51, which shaft 51 carries a second sprocket wheel upon the outside of the casing 2, as illustrated in Fig. 2 of the drawings, over which second sprocket wheel passes a sprocket chain 53. The sprocket chain 53 then passes over a sprocket wheel carried by the crank 13, thereby making the rotation of the drum 12 possible by the operllll til

asagna ation of the crank 13 upon the outside of the casing 2. A ratchet wheel 54 is carried by the shaft 51 and is adapted to be engaged by means of the pawl 55 to limit the rotation of the shaft 51 to one direction.

By carefully considering Fig. 12, it will be seen that the submergible float 41 is provided with a plurality of cables 56 connected to the float 41 by means of the eyes 57 to keep the float 41 from twisting While the same is being submerged.

It should be understood that the grapple hook 17 is placed upon the cable 7 prior to the assembling of the sections of the hook by means of the pin 21 passing. therethrough.

The inverted grappling hooks 45 are connected to the cable 25 and these inverted grappling hooks 45 which are adapted to engage the submergible float 41 comprise a pair of sections 48 which are clamped around the cable 25 and held thereon by means of the bolts 49.

Ears 60 are connected to the lower ends of the sections 48 by means of the pins 61 and springs 62 are wound upon the pins 61 and have their respective ends fitting in the sockets 63 and 64 carried by the ears 60 and sections 48 so as to normally hold the ears 60 in a spread-apart relation.

It should be understood that as many of these submergible floats may be employed as are found necessary and these floats are adapted to have the hoisting cables 25 pass therethrough and the inverted grappling hooks 45 may be passed through the channel 45' formed in the submergible floats 41 in view of the fact that the ears 60 may be folded inwardly and permit the grappling hooks to pass through the apertures 45 as will be obvious by considering Fig. 12 of the drawings;

It should be understood that by having the frame which supports the drum pivotally mounted so as to constitute a cradle, the cable may be at all times in an upright position, should the sunken ship swing or turn toward one side.

It should be further understood that the present device is susceptible of being used upon any form of vessel and it is not de sired to restrict the present invention.to the raising of submarines alone for the reason that any form of vessel may be raised in a similar manner as described above.
