sUBnAn'rNE Boar.

hattan, in the county `and State of New York, have invented new andi useful* Improvements in Submarine Boats, of which y marine.

the following is a full, clear, andexaot description.

My invention relatestor improvements in submarine boats, and more particularly embodies a life-boat for attachment to a subL marine craft, for rescuing the crew of the said-craft shouldl the same sink or in any manner become dangerously disabledwhen beneath the surface of the water.v

An object of my invention is to provide alife-boat for removable attachment to a sub- 'marine craft, the said life-boat being secured in such a manner that the same can be released by the crew or one of the crew, in a very short space of time.V

A further object of my invention is to provide a life-boat removably secured to a submarine, and adapted to be releasedl from the submarine from the interior of the lifeboat after the crew have entered the same; and a still further object is to provide means whereby both the submarine and the lifeboat are left absolutely water-tight, at the point of connection of the two boats, after the life-boat has been released from the sub- Reference is to be had to the accompanying drawings forming a part of this specification, and in which similar characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a side elevation of a modern- `submarine, boat equipped with my life-boat; Fig. 2 is a sectional view taken on the line 2--2v in Fig. 1; Fig. 3 is a fragmentary plan view of the floor ofthe life-boat, showing the closed passageway or man-hole for entering the llfe-boat from the submarine and the means for releasing the life-boat from the submarine; Fig. 4 is a sectional elevation taken on the line 4-4 in Fig. 3; and Fig. 5 is a sectional view taken on the line 5 in Fig. 4, looking in the direction of the arrow.

Before proceeding with a more detailed description of my invention, it will be wel] to state that my device can be attached to all forms and kinds of submarine craft, and' M Specification of Letters Patent. Patented June 6, 1911, Application. Iled' January 28, 1910i Serial No: 540, 508.

is particularly designed and adapted for use ony submarine boats in warfare, where greatV dangers fromk disability are ofttimes encountered. In previous devices, for attachment to'submarine craft for the urpose of rescuf ing the crew should any (lnger occur, the rescuing means are operated from the interior of the submarine, thereby necessitating leaving one of the crew in the submarine to operate the rescue means `to release the remainder of the crew. Furthermore, many types of lifeboatsfor the purpose mentionedv are insecure, faulty in construct-ionv and'. diifficult to operate. In my device is embodied a safe, reliable, easily operated lifeboat, removably secured to the submarine and adapted to be speedily released from the submarine. f

Among other features of my invention are the means on the submarine for kee ing the same intact and free from water, at t e# point of connection of the lifeboat and submarine, after the lifeboat has been released. from the submarine. i

Referring to the various figures, I employ a submarine boat 10, provided with the usual tu-rret 11, adjacent to which is removably secured a lifeboat 12. My lifeboat is preferably oval-shaped and consists of a shell 13, having suitable longitudinally and transversely secured braces 14. In the 'upper side of the shell 10 is located a manhole 15, closed by a removable cover 16, provided with handles 17 Opposite the` manhole 15, in the floor of the shell 10, is a second manholel leading into the submarine boat 10, and closed by removablev safety plates 18 and 18, secured to the shell 13, and a removable cover plate 119, secured to the submarine 10. v

Secured to the plating of the submarine 1() is an annular chamber 20, independent of the main chamber of the submarine. In the shell 13, screw threaded lugs 21 are provided, each having a hole longitudinally therethrough and adapted to receive a bolt 22, ypassed through the plating of the submarine and lifeboat before the chamber 20 is secured to the submarine, as will be easily seen by referring to Fig. 4. The head 23 of the bolt, in the chamber 20, is adapted to slide 1n a grooved member 24, so that Should;

thebolt drop downward it will at all times remain in a vertical position, owing to the grooved member 24. This construction can pierced Fig 2. Suitable smaller gas be most easily discerned by reference to Fig.l 5. Now when the bolt 22 has been through the plating and lug 21, as described, the screw threaded portion of the bolt projects upwardly beyond the edge of the lug 21. The proportion between the number of threads on the lu 21 and the number of threads 25 of the that when Ia cap cover 26 in thel form of a gear or pinio-n is screw-threadedly secured to the lug 21, as shown in Fig. 4, the gear 26 will be secured to the lug 21 half-way before the gear 26 engages the screw threaded portion 25 of the bolt 22, the reason for this construction being more fully explained hereinafter. v

A hexagonal top 27 is provided on the gears 26, or moreeasily gripping the gear 26 with arwrench or like member, shown in dotted lines in Fig. 4. A complete interconnected series ofrbolts and gears, such as has been above described, 'and as shown in Fig. 4, are provided, as will be most clearly seen by referring to Figs. 2 and 3. A large,

circular gasket 28 i'sprovided intermediate the lifeboat 12 and the submarine 10, and is by the bolts 22, and adjacent the said gasket a' second solid circular gasket 29, is provided, as will be clearly-discerned in ecs 30, g1, 32 and 33 are employed to prevent any leakage ,of water, and dis osed between various joints, as shown. Tlie chamber 20 has aremovable end 34, provided to enable easy access to the chamber 20. It will be dis tinctly understood that the covers 18 and 18* are not secured to the ioor of the life boat until the life boat is ready to be released from the submarine.

Now should the submarine 10, equipped with the life boat 12, become disabled and sink, the crew can immediately remove the cover plate 19, crawl into the life boat 12 and replace the cover plate 19. This prevents the submarine from filling with water at this point. The safety covers 18 and 18l are then secured in place and then by turningthe gears 26 thev bolts 22 holding the .life boat to the submarine will be released from connection with the life boat and the life boat will rapidly rise to the surface, where the v the surface of the water is reached in theA upper cover 16 can be removed, enabling the crew to get fresh air and to signal to a larger craft to rescue them. Suitable oar locks can be provided on the outside of the life boat, and a supplyof food and oars can at all times be stored in the life boat. Then when life boat, the crew need have no'fears if a vessel is notI in sight, asthe life boat can be propelled through the water by means of the oars. Referring again to the bolt 22 in Fig. 4, when the gears 26 are turned torelease the same from the lug 21, it will be seen that owing to the proportion of the number olt 22, is calculated, so

of threads as heretofore described, on the lug and the bolt, the bolt will drop or be disconnected from the gear 26 when the gear is half disconnected from the lug 21. New by em' loying the grooved member 24, the bolt is eld vertical after disengagement with the gear 26, and in being so held has a tendency to prevent an excess of water from trickling throughthe bolt hole in the plat.- ing into the chamber 20, and after the bolt is disengaged as heretofore mentioned., the gears 26 are rescrewed on the lugs 21 and thereb prevent any water from getting into the li eboat through the bolt holes in the lugs 21.

Although I have described my invention as shown, it will be understood that I do not limit myself to the construction shown, the scope of my invention being fully disclosed in the appended claims.

Y' Having thus described my invention, I
