SUBMABHIE LIFE SAVING DEVICE.

APPLICATION EILED HAR.25,1914.

The end of said support serves as a Stop to arrest the bar when it is swung into position diametrically oi the man-hole and, to .it the bar being a fidczitally retracted ch stop, I pzoi'ide a latch 36 to en- 0 bar f om the side opposite the stop. bar is formed with a screw-tlireaded e l? which is vng'agcablc by the threaded owcr nd :29 o'. the l.v 1g when the bar is located medially of the man-hole 12. The king-screw is pea'n'idcd at its upper end with an operating haudl' and a socketwrench l he heads of the various i re .wnts a plate to." a man-hole 4:1 in the root of the vessel and is desirably seated upon a combing or wall -13 which extends aboie said root so that, when the vessel floating and the plate -10 is removed, the combing prevents the waves or wash which 'may flow over the root from (-ntm'ing the vessel. Openin s, such as lvl, are provided in the peripheral wall of the vessel for light or ventilating purposes and may be glazed or otherwise, the same bei ng protected by guard-plates 5) which are detachably connected to the wall of the vesssl by screw-bolts al-O which are removable from the interior of the vessel.

i age valves 17 or an equivalent, located above and below the height of openings 74., are used to determine when the vessel has reached the surface and if the openings l-lare exposed, to allow the removal of the plates 4 The operation of the invention is as follows: In preparing to leave the boat, the crew enter through opening 13 into compartmcnt 10 and thence ascend through manholes 12 and 1-) into the vessel V. Before the last person leaves the compartment, the door ll is closed and secured by the screw-bolts 15, as shown in Fig.

When all hands are in the vessel the bridge- .bar 32 is swung from its dotted line position A (Fig. 3) into the full line position whereat it is held by the latch 36, as illustrated in Fig. 4. The man-hole cover 25 with the king-screw therein is now placed over the man-hole 19 and the cover then fastened down by screw-bolts 50. The kingscrew is now rotated by its handle 38 to engage in the hole 37 of bar By holding the handle of the king-serew to prevent the latter turning and by screwing the nut 28 hard down against cover 25, it may be ascertained whether the king-screw is sufficiently engaged with the bridge-bar 32. -When this is deemed satisfactory, the bolts 23 are successively unscrewed from their engagement in the holes 24 whereupon the king-screw alone serves to couple the vessel V to the boat. Consequently, to release the vessel the king-screw is turned to withdraw screw-threads of the bar-hole 37. As this is accomplished the vessel ascends to the surface of the water. When the king-screw disengaged from the bridge-bar 32 the tormer is raised to bring the shoulder 30 of the king-screw against the top of recess :31 to coact therewith to close the opening, if any, which may obtain about the kingscrew in the hole 26 of the cover 25, and whe e-at it is secured by means of the nut .28 "\i'llltfll is screwed down against the cover,

as clearly shown in Fig. 2-.

"Various changes may be made from the aforedcscribed embodiment of the invention as, for example, the upper portion 16 of the ves e may be more or less housed in a nty provided in the deck, as indicated by I and 52, respectively, in Fig. 1.,

What I claim as my invention, is

1. in apparatus of the class described, a floata'tive vessel provided with a man-hole in its bottom, a cover therefor, a. king-screw extending through the cover, and means provided on a submarine boat for engaging the screw below said cover whereby the vessel may be detached from the boat by operating the screw. v

:2. In apparatus of the class described, a. l'loatative vessel provided with a. man-hole in its bottom, a cover therefor, a king-screw extending through the cover, a nut engaging the screw above said'cover for regulating .the king-screw when the same is inoperative, and means provided on a submarine boat for engaging the screw below said cover whereby the vessel may be detached from the boat by operating the screw.

In apparatus of the class described, the combination with a boat having a well therein, a horizontal partition dividing said well and provided with a man-hole, and a. bar extending across said man-hole and having a screw-threaded hole therein, of a floatative vessel provided with a man-hole in its floor, a removable cover for the last named,

man-hole, screw-bolts for normally securmg said vessel to the boat, a king-screw extending through said cover and engaging" with the threads of said bar-hole for holding the vessel to said boat subsequent to the disengagement of said screw-bolts from the boat, and means interposed between the vessel and said partition to afford a nonleakable passageway between the aforesaid man-holes.

1. In combination with a submarine boat having .a well in its deck provided with a. partition to afford a compartment therebelow, an opening provided with a door for the admission of people into said compartment, a man-hole provided in said partition, a bar adjustably connected to said partition and extending across said man-hole,
