9 Claims, 4 Drawing Figures DEEP OCEAN SUBMERSIBLE STATEMENT OF GOVERNMENT INTEREST The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
BACKGROUND OF THE INVENTION In recent years the Navy and oceanographic industries have been seeking new types of submersibles which can be taken to great depths within the ocean. A very promising approach now exists in utilizing a spherical glass shell which is split into two hemispheres and joined together about the rims thereof. It has been found that a glass sphere increases in strength as it is taken to greater depths within the ocean and provides a simple compartment for crew members to visually witness the outside ocean environment. A present means of joining the two glass hemispheres together has been a metal band which extends about the rims of the hemispheres and which may be retained by tie straps which extend from the respective rims across the hemispheres. This approach would not be satisfactory for deep ocean depths because of the difference of modulus of elasticities between steel and glass. For instance, an 80 inch glass sphere with a 2 inch wall would change in diameter, at a depth of 20,000 feet, approximately three-fourths of an inch. The change in diameter for an equivalent steel band would be about one-fourth of an inch. The difference between the two deflections would produce enormous local bending stresses where the glass joins the metal. Further, a metal fitting at the equatorial joint of the glass sphere would weigh approximately 675 lbs, thus reducing the efiective payload of the submersible.
SUMMARY OF THE INVENTION The present invention provides a retainer means for the two glass hemispherical shells which would be effective at great depths within the ocean without any danger ofreleasing the shells or producing breaking stresses at the rims of the shells. This has been accomplished by providing each hemispherical shell with a peripheral lip which extends outwardly from the shell rim, an elastomeric band mounted to each respective lip, and means for clamping the bands so that the shells can be tightly retained about their rims. The band has substantially the same modulus of elasticity as the glass shells and therefore changes in shape substantially as the shells so as to obviate undue stresses on the glass. A
slight prestressing of the elastomeric bands has been found to ensure no separation of the bands from the hemisphericalshells. A unique joint has been provided between the shell rims, bands, and the clamping means which will be described in detail hereinafter. Further, a unique means has been provided for sealing the joint, preventing lateral displacement of the shells, and releasing the shells in the event of an emergency.
STATEMENT OF THE OBJECTS OF INVENTION An object of the present invention is to overcome the aforementioned problems associated with prior art retaining means for a pair of hemispherical glass shells.
Another object is to provide a glass deep ocean submersible which can transcend great depths within the ocean.
A further object is to provide a deep ocean glass submersible with improved retention means, releasing means, and sealing means for operation within great depths of the ocean.
Other objects and many of the attendant advantages of this invention will be readily appreciated as it becomes better understood by reference to the description and accompanying drawings which follow.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an overall view of a deep submersible glass shell with improved retention means for joining a pair of hemispherical glass shells.
FIG. 2 is an enlarged view of a portion of the retention means of the glass submersible.
FIG. 3 is a view taken along plane IIIIII of FIG. 2, and
FIG. 4 is a view taken along plane IVIV of FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawing wherein like reference numerals designate like or similar parts throughout the several views there is shown in FIG. 1 a deep ocean glass submersible 10. This submersible may be a pair of substantially identical hemispherical shells l2 and 14 which are joined at their rims by a band-like retainer means 16. This submersible may be mounted within a framework with propulsors (not shown) for exploring great depths within the ocean. Crew members within the glass sphere will have visual access to the ocean in almost every direction.
The glass shells l2 and 14 mate with one another about their rims to form the glass spherical hull. The shells 12 and 14 have peripheral lips 18 and 20 respectively, which extend outwardly from the rims thereof. The retainer means 16 may include substantially identical elastomeric bands 22 and 24 which are mounted to the lips 18 and 20 respectively. These bands are preferably constructed of fiberglas so as to have substantially the same modulus of elasticity as the glass hemispheres 12 and 14. In the preferred embodiment these fiberglas bands 22 and 24 are mounted to the glass lips 18 and 20 by a socket or tongue and groove type connection as illustrated in FIG. 3. Also, the bands 22 and 24 are preferably prestressed so as to ensure no departure of these bands from the lips 18 and 20 as the submersible descends within great depths of the ocean.
A means is provided for clamping the bands 22 and 24 so that the shells 12 and 14 can be tightly retained about their rims. This means may include a'series of toggle clamps 26 which have top and bottom clamping members 28 and 30 which are pivoted at 32, and a release tab 34 which is pivoted at the top of the clamp member 30 at 36. The bottom clamp member may be fixedly secured to the bottom fiberglas band 24 by a series of screws 37. Because of the difference in modulus of elasticities between the toggle 26 and the fiberglas bands 22 and 24 it is desirable that the top of the top band 22 and the bottom of the bottom band 24 be rounded and that the clamp members 28 and 30 arc about these rounded portions for positive retention at all operating depths within the ocean. The bottom fiberglas band 24 may be provided with downwardly extending attachment lugs 38, one of which is illustrated in FIG. 2.
It is essential that a perfect seal be made between the glass hemispheres 12 and 14. As illustrated in FIG. 3 the rims of the hemispheres have flat faces 40 and 42 and rounded exterior edges 44 and 46. A gasket 48 is disposed between the flat faces of the shell rims and has an outer peripheral enlargement 50 which is squeezed between the rounded exterior edges when the glass hemispheres are brought into mating engagement. In this manner a very desirable seal is made about the rims of the glass hemispheres.
In an emergency situation it may be desirable for the crew within the deep submersible to release the toggles 26 and open the hemispheres for escape purposes. In order to accomplish this the pivots 32 and 36 of the toggle 26 may include an explosive bolt which may be actuated by an electric current from within the glass submersible. In order to feed this current to the explosive bolts foil leads 52 may be embedded within the gasket 48 and may follow the gasket from an interior extension 54 of the gasket to an exterior extension 56 thereof. The foil leads 52 within the exterior extension 56 of the gasket are electrically connected to the explosive bolts within the pivots 32 and 36 (not shown).
After the toggle 26 has been released from the glass hemispheres it will be necessary for the crew to apply some parting force for separation. This may be accomplished by providing a rigid peripheral extension or guide 58 which is connected along the interior surface of the bottom glass hemisphere 14 and which extends upwardly in close proximity with the interior surface of the top glass hemisphere 12. Within the guide 58 is a quad ring 60 which makes peripheral sealing engagement with the interior surface of the top hemisphere 12. With such an arrangement the crew can utilize a gas bottle for applying a pressure within the submersible which is slightly greater than ambient so as to separate the glass hemispheres l2 and 14. The peripheral guide 58 also serves as a means for guiding mating engagement of the glass hemispheres l2 and 14 and preventing lateral displacement thereof.
It is now readily apparent that the present invention provides a glass submersible which has many unique advantages. The retaining means for the pair of glass hemispheres has substantially the same modulus of elasticity as the hemispheres and will not cause undue stresses during deep ocean operations. A sealing means is provided for ensuring a perfect seal at great depths within the ocean and a means is provided for releasing the hemispheres in case of an emergency situation.
Obviously many modifications and variations of the present invention'are possible in the light of the above teachings. It is therefore to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
