To all whom it may concern:

Beit known that I, VICTOR C. CoUvRETTE, a citizen ofthe United States, -and'a resident of South Bend, in the countyof Pacific land State ofWashington, administrator of the estate of CHARLES LOUIS CoUvRETTn, de-

ceased, late a citizen of the-United States and late a resident of Goldendale, in theinvention.

The object ofthe invention is to provide means for carrying ships launches, particularly launches to be used in emergencies,

such as loss of the vessel. n l

Another object of the invention is to so arrange the means for carrying the launch that the launch may be quickly and safely put into the water at any time and under any conditions. This endis attained by constructing in the ship a water-tight compartment, which runs thwartwise from side to side, and which is provided at each end with .doors forming the outer walls of the ship,

which doors may be closed and hermetically seal the compartment when the launch is not in use, and which upon lopening the doors will permit the water to flow into the compartment so that the launch may then be water-borne therein and may bevoated out of the compartment into the sea. This permits the employment of a powerful launch or motor driven boat of large size, and to handle the same expeditiously and easily.

The invention involves various other features of major or minor importance, all of which will be -fully set forth hereinafter and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings which illustrate as an example.A

the preferred embodiment of the inventlon, in which drawings*n Figure 1 is' a partlalside view of a `ship lto which the invention is applied; Fig. 2 is tight compartment; Fig. 5vis a detail view ofone ofthe braces which are employed for said doors; Fig. 6 is a detail .section of the jack by means of which thelaunch. is held steadily in its compartment; and Fig. 7 is a detail section showing the gear for operating the lower sections of the doors of thevcompartments. 4

As shown in Figs. 2 and 3, the vessel is provided with a 7compartment 10 which eX- tends transversely across the vessel from side to side. This compartment is 'watertight,and is provided 'with a pipe 11 for filling it, and a pip'e 12 by which the water may be withdrawn. This pipe 12 passes to any convenient point`for the disposition of the water, which may be either a pump for expelling the water from the bilge of the vessel or a ballast tank in the bottom ofthe vessel. These pipes 11 and 12 are controlled by gates 1li operated by screws 15,A the upper ends of which are provided with wheels 16 facilitating the operation of the screws.

The compartment 10 is entirely watertight 1n its construction,- and at each end it is provided -with an`upper sliding door section 1f? and a lower hinged door section 18. These Vdoor sections match to form a hermetic closure for the endsA of -the compartment. The lower section 18 of each door is hinged at its bottom, as indicated at 19, and provided with chains 20 for limiting the downward or opening movement of the door section. For returning the door section to closed position curved racks 21 are hinged to the door section, and their inner ends run through guides 22. With these 24 'adapted to be operated by pawls 25 and levers 26. The door sections 18 areI adapte -to be started out of the easement by means of screws 27,-which operate in nuts 28 held stationary, as shown ybest in Fig. 7 and for operating the screws ratchets 29 are provided, with which ratchets pawls 30 and levers 31 co-act. In order to' open the door sections 18, therefore, the screws 27 should be operated until they engage the door sections and pushA them away from the casements, whereupon the door sections will fall to horizontal position and will then be checked by the chains 20. The door sec'- tions 18 are returned by operating the gear 23 on the rack 21. y

The upper door sections 17 match against the lower door sections 18 and slide in suitable. guides constructed in the hull of the piston rods 32, the pistons (see the broken lines in Fig. 4) 33 of which operate in cylinders 34 secured in the vessel. To these cylinders steam-pipes 35 lead, so that steam may be applied at the desired moment to raise the door sections, as shown at the left-hand side of Fig. 2. 'For bracing the structure when the door sections 18 are closed, hinged braces 36 (see Figs. 4 and 5) are provided.` These braces are adapted to swing down against the inner sides of the door sections and the adjoining edges of the walls of the ship, as shown in Fig. 4, and when the doors of the waterftight compartment are opened -the braces are lifted up into the position shown in Fig. 2,by means of a weight 37 connected to the braces by cords 38. It is understood that the braces 36 are hinged or` pivoted at their ends on suitable supports within the ship as indicated in Fig. 3, so that the braces can be swung u into inactive position as shown to the le t in Fig. 2, or downward into active position as'indicated tothe right of Fig. 2' and in Figs. 3 and 4 to brace the structure when the door sections 18are closed.

YThe launch is represented at 39 in the drawings. This launch should be as large as the size of the compartment or other considerations will admit, and constructed so that it may be used in rough weather. The launch is provided with acks, shown in Figs. 2 and 6, for engaging its gunwales to steady the launch. Said jacks comprise (see Fig. 6)

slides 40, operating in guides 41 and actuated by screws 42 having wheels 43 at their upper ends for manipulating them. A hinged stair 44 is provided to permit convenient entrance into the compartment, and this is connected with aA tackle 45, enabling it to be raised at will.

In the use of the invention, supposing-it is desired to sendthe launch out from the vessel, steam should be admitted to the cylinders 34 at the side from which it is (lesired to send out the launch, thus raising the door section 17 at said side.y The screw 27 at saidl side should thenbe operated'to start the dropping movement of the door section 18, said movement being checked by the chains 20. Previously, water should have been admitted to the compartment through the pipe 11, thus floatingl the launch, and as the dooris opened the-water will instantly find y'itsletel in the compartment. Steam or other motive power being ready to'be instantly applied, the launchmay then 'be taken by 'its own power out `ofthe compart-A ment into the open sea. After the launch is sent from the vessel, the door sections may be again closed and the water pumped out of the compartment, if desired, or the doors may be kept opened. until the launch returns.` It will be observed that ,this invention avoids the` necessity of lifting the launch bydavits or other tackle, and it permits the employment of a far more powerful the'vessel may be detached and ire started in the furnace ofthe launch boilers, If an engine of the internal combustion or exllaunch than any heretofore carried by marine vessels by means of which launch perplosive type is employed the necessary fuel should be kept at all times in the launch.

By placing the water-tight compartment thwart ship, a minimum of room is required for the launch, since the said launch may be passed directly through the side ofthe ship and at a right angle thereto, which would not be the case were'the compartment arranged longitudinally. By this construction also more boats can be accommodatedthan when the chambers are placed lengthwise of the vessel, and each boat can be launched independently of the other, since they may be placed side by sideand` with an opening directly in front or behind. Although reference is particularly mad to launches, it is expressly understood that other marine vessels, such as submarines,l

may be carried by ship in the manner stated.

Having thus described the invention theV following is claimed as new and desired to be secured by Letters P atent- 1. A'marine vessel having a water-tight compartment therein, a `hingeddoor and a sliding door for closing the '-compartment,

said door being hinged to open downward,

I

3. A marine vessel having a water-tight compartment therein, a hinged door and a sliding door for closing the compartment, said hinged door being hinged to open braces within the vessel for bracing the doors, comprising pivotally mounted U- shaped members whose body portions engage the doors.
