No. 49,922 7 liaims. Cl. 9-4) The present invention relates to a survival capsule or lifesaving craft for use on sea vessels, and particularly adaptable to use on lake boats, and one which can be easily launched.

As is well known, the open type lifesaving craft is good only for abandoning a ship in case of fire or other disaster in a mild sea. The chance of survival in an open lifeboat in rough or stormy weather, such as is frequently encountered on the Great Lakes, is low because the open lifecrafts will fill with water and will otherwise capsize in heavy seas. Moreover, prior lifecrafts have been diflicult to launch in a heavy sea. Moreover, on lake boats and the like, if one can generally survive for a day or so, rescue will be at hand so that provision need not be made for survival over a long period of time.

It is therefore an object of the present invention to provide a type of survival capsule which is practical to manufacture and which will provide protection from the weather and which will stay afloat in rough seas without capsizing.

It is a further object of the present invention to provide an improved type of survival capsule which is easy to launch.

it is yet another object of the present invention to provide improved means of obtaining stability in an enclosed survival capsule.

Further objects and advantages of the present invention will become apparent as the following description proceeds and the features of novelty which characterize the invention will be pointed out with particularity in the claims annexed to and forming a part of this specification.

Briefly stated, the survival capsule includes an enclosed shell or hull of generally oblate shape having a perforated stabilizing dish-shaped member attached to the lower end of the bottom or hull of the capsule so that as the craft rides a wave water will be permitted to flow through the perforations of the member and the craft will be maintained at its floating level without being dragged down as the water goes through the holes, thereby producing a stabiling efiect to keep the craft in an upright position. The enclosed hull is preferably made of molded glass fiber material and includes a top shell of generally inverted dish shape, a lower shell of dish shape, and an intermediate seating shell. The inte mediate shell and the lower shell provide an air space therebetween so that the bottom of the capsule is of double hull construction. When not in use, the survival capsule is secured to brackets on the deck of the boat and securing means are provided for securing the capsule to the bracket. When the securing means are released, the capsule rests on the bracket and is prevented from sliding therefrom by guides on the brackets or capsule. The capsule can be floated up or out from the brackets but cannot slide from the brackets until such time as it is floated. Ventilating air can be supplied to the capsule through a retractable tube.

The nature of the invention will thus be understood when described in connection with the accompanying drawings, in which:

FIG. 1 is an elevational view of the improved survival capsule secured on the deck of a boat;

FIG. 2 is a plan view of the improved survival capsule of FIG. 1;

FIG. 3 is a cross section elevational view of the improved survival capsule;

FIG. 4 is a partial sectional view or" the survival capsule illustrating the ventilating tube and taken along line -44- of FIG. 2;

FIG. 5 is a partial sectional view of the survival capsule illustrating the arrangement for pumping leakage water from the capsule and taken along line 5-5 of FIG. 3; and

FIG. 6 is a partial sectional view illustrating towing and hoisting means of the capsule and taken along line 6--6 of FIG. 2.

Referring now to the drawings, and specifically to FIGS. 1, 2, and 3, a survival capsule shown generally at it) is a generally oblate or bulbous shape and constructed or" molded glass fiber material and includes an upper inverted saucer-shaped shell 12, a lower saucer-shaped shell 14 and an inner or seating shell 16, each of the shells being provided with an outwardly extending rim or flange portion 120, 14a, and 16a, respectively, radially about its outer periphery. The shells are secured together at their flanges by any well-known means such as cementing the glass fiber material or by use of gaskets and bolts.

In order to stabilize the capsule and to keep the capsule right side up in water, the capsule is provided with a perforated stabilizing dish-shaped member or hull l8 having a plurality of perforations 18a, and secured to and spaced from the lower shell 16 by a plurality of members or brackets 20. As the capsule rides a wave, the Water flows through the perforations 1811 so that the craft is maintained at its floating level and is not dragged down. As the water passes through the holes it gives the capsule a stabilizing effect to keep the capsule in an upright position. The inner or seating shell 16 and the lower shell 14 are spaced apart and form an enclosed air space 17 thereby providing a double lower hull construction to the capsule. In order to provide for entry into the enclosed capsule, the upper shell 12 is provided with an entrance opening or hatch 22 at the center top thereof, and a watertight blister type hatch cover 24 is provided and adapted to be secured over the hatch 22. The batch cover 24 is preferably transparent so as to provide a lookout or observation bubble for the craft. The hatch cover 24 is pivoted to the upper shell 12 by a hinge 26 and is secured in the closed position by a hand wheel 28.

To secure the capsule lit to the deck of the boat (not shown) there are provided three deck brackets or capsule supports 3%} (FIGS. 1 and 2) secured to the deck of the boat and spaced so that the outer flange portions 12a, 14a, and 16a of the shells rest on the upper surface of the supports 3h. A pair of side guide stops 32 is provided on the lower side of the craft edge extending from the flange 24a at each of the deck brackets 3i) and adapted to slidably engage the sides of the deck brackets 39, so that the craft can be moved only upwardly from the supports, and cannot slide sidewardly from the supports. A readily releasable means or threaded pin 34 extends through the flange portions 12a, Elba, and 14a at each of the supports 3%, and is threadedly secured to a threaded aperture 39a in each support 3% to secure the craft to the supports.

in order to provide ventilating air to the inside of the capsule ii there is provided the ventilating means shown generally at 4% and best illustrated in FIG. 4. The ventilating means includes a retractable ventilating tube 42 of stainless steel which is slidably secured in a brass tube fitting 44 and which extends through an opening in the upper shell 12 of the capsule iii. The upper end of the tube 42 is provided with a dome-shaped splash guard 48 secured in spaced relation over the upper end of the tube 42 by a plurality of struts 49. An outer tube fitting St is provided concentric with the tube 42 through which the tube slidably passes. The fitting 50 is provided with a flat upper surface Ella having a rubber sealing member 52 about its outer periphery against which the outer periphery of the guard is adapted to seat when the tube 42 is in the lower position as illustrated in FIG. 4. The tube fitting 44 and the fitting 58 are secured to the upper shell 12 by a plurality of fastening members 54. When it is desired to provide ventilating air to the inside of the capsule, the tube 42 can be moved upwardly so that the seal between the guard 48 and the fitting 56 is separated. To hold the ventilating tube 42 in its upper position, a slot 56 is provided near the bottom of the tube 42 so as to receive a prong 58 in the fitting 44. When not in use, the ventilating tube 42 would be inside the capsule 10 and the splash guard 48 would form a watertight seal against the fitting 51 to prevent the seepage of water. Each occupant of the capsule It would be provided with oxygen means such as an oxygen bottle and a mask fastened beside him for use if needed.

To provide for hoisting or. towing the capsule it the capsule 10 is provided with a pair of U-bolts 6%) (FIG. 6) fastened through the outer edge or flanges 12a, 14a, and 16a, and secured thereto by a pair of upper nuts 60a and a pair of lower nuts 6%.

Inorder to provide for seating of the occupants in upper annular seating portion 16b and a recessed cupshaped portion 160 which provides for .foot space for the occupants. A disk portion 16d is disposed across the bottom of the cup-shaped portion 160. Moreover, a center compartment or observers seat 62 is provided which serves as a seat for a lookout under the transparent hatch cover 24 and which also serves as a' step to facilitate entry into the capsule. The compartment 62 is provided with a door 64 and contains flashlights, flares, food, and the like. 'If desired, the lookout,,as well as the other occupants, may each have built under them a built-in disposaloe for personal waste and provided with a snapon cover. Alternatively, plastic bags may be stored in the compartment 62.

In order to provide for removal of seepage water from the capsule it there is provided a hand water pump shown generally as 68 (FIGS. 3 and and secured to the outer side of the compartment 62. The pump intake extends into a well 79 set into the portion 16d of the inner shell 16 to provide a low spot for the accumulation of the seepage water. The pump exhausts through a hose 72 to the outside of the shell 12 through the pump outlet 74 (FIGS; 1, 2, and 3). A valve 76 is pro- 1 vided in the hose 72 inside the capsule 10 to prevent the have been thrown overboard or who are otherwise floating about in the wreckage area, the capsule It} is provided with an outsiderope 82 (FIGS. 1 and 2) and a plu-. rality of bobbers 84. The rope 82 is secured to the outer flange portion 12a, 14a, and 16a, and provides a place that persons may hang onto.

If it were desired to enter and launch the capsule 1%,

. the threaded pins 34 which hold the craft 10 to the supports 30 would be cranked out so that the craft would be free" to float upwardly. Even with the pins 34 removed and with the boat rocking in rough water the capsule 1% would not slide around and would remain on the support 39 due to the restraint of the guides 32. The capsule it), however, would be merely resting on the support and if the boat were to sink from underneath the capsule the capsule 1!) would then float on the water.

In order to enter the capsule 1G, a person could climb the steps 78 on the support 39 and climb the steps 84} on the upper shell 12, then enter the shell through the entrance hatch 22 with the hatch cover 24 open, stepping down on the lookouts seat 62, and take a place or posil the capsule 10, the inner or seating shell to includes an I tion on the seating surface 161) of the inner shell 16. A

safety belt (not shown) is provided for each occupant After the lookout enters the capsule It), the transparent watertight hatch cover 24 would be shut and would be fastened by tightening the threaded hand wheel 28. The occupants, including the lookout, would be seated in position and strapped by safety belts. The occupants who are seated on the inner shell 16 will help to stabilize the craft. When the capsule it} is launched by the sinking or destruction of the boat, it would land right side up as this is the manner in which it rests on the brackets. The people who would be sitting within, with the hatch cover 24 closed, would aid the balance of weight so that the capsule would always tend to float right side up. Moreover, if the capsule it} were to land upside down in the water, it would tend to right itself due to the balance of the weight of the people strapped in their seat and the added bottom stabilizing member 18. Once the capsule 1% is floated right side up, the perforated member 18 is filled and surrounded with water and it serves to holdthe capsule right side up. The lookout, seated on the compartment 62, can see through the transparent hatch cover 24 and he can open the hatch for air as desired.

While a preferred'embodiment of the present invention has been described by way of illustration, many modifications will occur to those skilled in the art. It is intended therefore in the appended claims to cover all a such modifications as fall within the true spirit and scope of the invention.
