This invention relates to a life boat and one of its objects is to provide a life boat which can be rightedwhen thrown to one side, or inverted, by controlling the ballasting water, and which cannot be flooded, either from heavy seas or through leaks in the outer hull or body of the vessel, and which will not sink when one or more punctures or holes are pierced through the outer hull.

Another object of the invention is to provide means for controlling the distribution of the possengers, so that excessive loading on one side or one end of the vessel, during stormy weather, or when launching the life boat, can be avoided.

A further object of the invention is the provision of means for enabling the operator in charge of the life boat to quickly shift the water ballast when the vessel is unbalanced in heavy seas or otherwise, so that it can be forcedto a correct floating position.

A still further object of the invention is to provide a cover for the top of the vessel, which will form a water tight seal for it.

A still further object of the invention is the provision of a life boat, in which provision is made for the storage of food and water, and oxygen gas, and further provision is made for receiving and transmitting radio messages.

With the above and other objectsin view the invention consists in certain new and useful con-' structions, combinations, and arrangements of parts, clearly described in the following specification, and fully illustrated in the drawings, in

which:

Fig. 1 is a vertical longitudinal sectional view.

Fig. 2 is a vertical transverse sectional view.

Fig. 3 is a top plan view, showing the deck cover removed.

Fig. 4 is a vertical transverse sectional view. Referring to the drawings illustrating the practical construction of my invention 5 designates the outer hull of the vessel, which is suitably shaped to provide s. forward end 6 and a. rear end I, and right and

left sides

8 and 8, respectively. Arranged along the sides of the vessel are a series 5 of rope handholds Ill, by means of which persons struggling in the sea may support themselves.

Against the right side 8 of the vessel a ballast tank II is arranged. This ballast tank is divided into a series of separate compartments l2. A ballast loading and controlling pipe I! is connected with each of such compartments.

Another ballast tank i4 is arranged against the left side 9, and is similarly divided into a series of separate compartments Ii. A ballast loading and controlling pipe I6 is connected in communication with each of said compartments.

Along the bottom I I of the vessel a compressed air tank I8 is disposed, being shown to be located midway of the sides of the tank, so that it occupies 5 a central longitudinal position. Over this tank a series of brackets l9 are arranged, on which the upright wall 20 is supported. On this wall the passenger seats 2| and 22 are arranged on opposite sides thereof. Spacers 23 are arranged along 10 these seats, which arein the nature of benches 'which extend longitudinally of the vessel.

Arranged against the right side 8 of the vessel and over the ballast tank thereof, is another seating bench 24, which is likewise provided with 15 spacers 25. Arranged over the ballast tank of the left side and against the left side of the mm, is another passenger seating bench 26, which is also equipped with spacers 21. The spacers prevent longitudinal shifting of the passengers in heavy go seas, toward the forward and rear ends of the vessel, while the intermediate longitudinal wall provides means for preventing the passengers on one side of the vessel from rolling toward and against the other side of the vessel. To retain 25 the passengers in position, restraining straps 28 may be arranged over the benches.

Against the floor of the vessel on the right side thereof a ballast tank 28 is arranged, which is divided into a series of separate compartments, 30 and against the bottom on the left side of the vessel another ballast tank 30 is arranged, which I is also divided into a series of ballast compartments.

The compartments of the right ballast tank ll 35 are connected by transverse pipes II with the compartments of the left ballast tank I, so that the compartments of both tanks will be arranged in opposed units, each compartment of the right tank being connected in communication with the 40 ment may be shifted to by heavy seas, or improper launching, or from other causes. 1

Flow from the units of each pair ofcompartments of the right and left ballast tanks is controlled by means of the pumping units 32, which are assembled inflow relation to the cross pipes 3|. All of these units 33 are connected by a single lineshaftfl toeachothenandmaybedrlvenby a hand wheel 35, or by means of a suitable air or other motor 36.

An air driven motor is preferred, and this may be operated by means of the compressed air supply contained in the tank l8, through the medium of the supply pipe 31, and the controlling valve 38. A float 39 is arranged in each compartment, and this float is connected to an air hose 4!], of flexible rubber, which in turn is connected with a cross air pipe, so that any compartment of the right tank will be able to discharge air to its twin compartment of the left ballast tank, when there is a shifting of the ballast water from such right compartment to the companion left compartment.

A manually driven air compressor 4| is arranged in the vessel, so that the passengers can recharge the tank l8 with compressed air, should they remain at sea for a prolonged period of time. When the ballast water is shifted from one com- 'partment to its opposite companion compartment, thenthe air from the compartment from which water is withdrawn will be increased from the air from the compartment into which water is delivered.

Should the vessel be inverted, the operator or person in'charge of the vessel would shift the ballast toward one side of the vessel, so that this side would tend to sink and thus produce a turning movement on the vessel. Should the vessel be caused to ride or float on one side, then the ballast water would be shifted to the uppermost side, so that gravity pressure would produce a turning movement of the vessel, thereby tending to shift the vessel to normal position. As the vessel-is righted to normal position the ballast water is returned to the compartments from .which it has been withdrawn.

One or more oxygen tanks 4| is arranged under the roof 42, which includes a central rigid section 43, and sliding sections and45. The outer edges of the sliding sections engage the water tight overlapping bars 46 and, 41, and may be secured'in closed positions by means of the locks 48 and 49. 1

An entrance hood 5!] is mounted on the centralroof section, and is provided with a water tight door 5|, which is also equipped with a smaller ventilation door 52.

The hull of the vessel may be lined or equipped with protected cork, so that under all circumstances the vessel will retain suflicient buoyancy to support itself against sinking; but each of. the ballast tanks is provided with sufficient air capacity to insure that buoyancy will be maintained.

The entire top of the vessel is completely covered, and ventilation may be obtained by means of the inverted air conduits 53 and 54, arrangedat suitable locations on the roof, so that a thermo circulation may be maintained within the vessel.

The bottom of the hull 5 is equipped with a cast metal keel fill, and the vessel is steered by means of the rudder 6|. A propeller shaft 58 extends rearwardly of the hull and is equipped with a suitable propeller 59. The propeller shaft is driven by means of the engine 58, arranged in a water tight compartment 55, and furnished with fresh air through the conduit 56, which extends upward into the cabin. This conduit terminates at the top of the compartment 56, so as to carry off the exhaust and another conduit 51 extends to a low level in the compartment 55, so that a good circulation is maintained in the engine compartment.

' The vessel is equipped with an engine room 55,

which is sealed against the inflow of water, in which a power plant or'engine 58 is arranged. The shaft 58' of this engine or power plant is equipped with a propeller 59 on its rear end. A weighted metal keel 60 is mounted on the bottom of the vessel, and this provides a guard for the propeller. Rearwardly thereof the rudder 6| is arranged. Air is supplied to the engine room 55 by the pipe 51, which discharges fresh air near the floor of the room, and exhaust air is discharged by a pipe 56, which taps the roof of the room.
