This invention relates to new and useful improvements in a safety device for boats. Its primary object being to provide oat means to prevent a ship from sinking. Said means being collapsible or foldable Within the sides of a ship and having operating mechanism whereby the device may be'extended outward as required.

A further object of the invention is to provide safety means for ships including a plurality of air containers to be extended outward from the sides of a ship or lateral support arms to prevent a ship from sinking or capsizing when disabled.

With these and other objects in view that may appear While the description proceeds the invention consists in the novel construction and arrangement of parts as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming part of this application and in which:

Fig. 1 is an end elevation of a ship showing the invention in use thereon.

Fig. 2 is a plan view of the same.

Fig. 3 is an enlarged view of one side showing the device in extended position.

Fig. 4 is an enlarged vievv showing the device in the partially open position.

Fig. 5 is a sectional view showing the invention in the closed position.

Fig. 6 is a sectional view of the safety device in the open position.

Fig. '7 is a fragmentary sectional view of the constructional details of the outer side.

Referring more in detail to the invention in which similar reference characters designate corresponding parts throughout the several views, it will be seen the invention comprises the hull I Il of a ship having open receptacle chambers II formed in the sides thereof designed to receive foldable structures hinged to the hull in a position to be inclosed in said chambers when closed.

The foldable structure consists of a box structure I2 having an open bottom and supported on the inner side by two foldable platform members I3 and I4 which are lsecured together by a central hinge I5 and to the structure I2 by hinge I6. The device is arranged with the hinges in position to permit the foldable members to be enclosed in the structure I2 and the entire de- 50v vice to be enclosed in the aforementioned chambers II.

The structure is actuated by toothed racks I'I operated by toothed Wheels I8 within the hull of the ship, and are supported in the open position by horizontal bars I9 actuated from a central gear 20 and arranged to engage the folding structures on both sides of the ship to lock the same rigidly in the extended position.

In Fig. 6 a modification of the device is shown wherein three interlocking box structures 2I, 22 and 23 are used. These are joined together with hinges 24 at the top arranged to permit folding of the same, and are constructed With rubber liners 25 to form an air tight structure on the top when open. The ends 26 as shown in Fig. '7 may also be folded inwards when the device is collapsed. These are constructed with a rubber layer 27 outside to prevent loss of air through the hinged joint.

While the outside or shell of the structure may be constructed of Wood, metal or other suitable material the same is preferably lined throughout with a cork lining 28 to add to the buoyancy of the structure.

From the foregoing it will be seen the invention provides means to extend safety floats on either side of a ship on whichwa railing 29 may be erected. In case of emergency the oats are projected laterally from the receptacle chambers in the hull and form safety platforms on floats upon which the passengers may walk if necessary and which will keep a boat afloat indefinitely until any damage sustained by the hull is repaired or the passengers removed from the same.

The device is believed to be practicable and an improvement in safety devices and Will also provide means to eventually salvage a ship that is temporarily abandoned.

It is believed that the construction and advantages of the structure shown may be apparent from the foregoing paragraphs taken in conjunction with the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed it is understood that minor changes in the details of construction, combination and arrangement of co-operating parts may be resorted to within the scope of what is claimed without departing from the spirit of the invention.

We claim:

1. In a safety device for ships, the combination with a ships hull having open receptacle chambers in the sides thereof, of a float comprising a boxlike structure open at the bottom land on one r side, a pair of hingedly connected platform members interposed between the sides of the ships hull and the float, the outer edge of one member being hingedly connected to the upper edge of the open side of said float and the outer edge of the other member being hngedly connected to the upper edge of the receptacle chamber, said platform members being adapted to swing downwardly into folded relation and foldable within said float when the oat is moved inwardly towards the receptacle chamber, arcuate rack bars connected at one end to said oat and extending into the ships hull, pinions in mesh with the inner ends of said rack bars adapted to move said rack bars to pull said oat inwardly and swing the same downwardly into nested relation with the receptacle chamber of the ships hull.

2. In a safety device for ships, the combination with a ships hull having open receptacle chambers in the sides thereof, of a float comprising a boxlike structure open at the bottom and on one side, a pair of hingedly connected platform members interposed between the side of the ships hull and the float, the outeredge of one member being-hingedly connected to the upper edge of the open side of said float and the outer edgesof the other member being hingedly connected to the upper edge of the receptacle chamber, said platform members being adapted to swing down-f wardly into folded relation and foldable Within said float when the oat is moved inwardly to- Wards the ships hull, arcuate rack bars connectedl
