SHIPS LIFE SAVING' APPARATUS Orgal Filed July 5, 1927 5 Sheets-Sheet 3 o l o I mum" Patented Apr. 8, 1939 TENT GFFIC JOSEPH KELLY, `Olli BOOTLE, ENGLAND vsnrrs Lrrn-snvme APPARATUS Application filed July 5, 1927, Serial No.` 03,609, and in `Grreat rtain July 10, 1926. Renewed February This invention has reference to the saving of life on shipboard, and has for its primary object to provide simple means `or appliances whereby a buoyant `or floatable structure may 5 be readily and conveniently, and Withall lirmly, secured to a ships deck, or the like, and rapidly detached or disconnected therefrom should occasion arise.

I-n theapplication of my invention to the provision of means for saviilg the lives of the crew of a submarineressel if andwhen submerged and unable to rise to .the vsurface of the Water, I provide a chamber fof vsuitable materia-l, size vand shape -or configuration and slidably carry or support in opposite `Walls or sides-and preferably near the `licor-- thereof, rods or shafts of suitable diameter for the intended duty anclof such length that a portion of each, `exterior to the Iol'ramber., may be engaged with "and "so anchored to a bollard, bridle, bracket, or the like, fixedly secured to the deck `of the vessel, whilst a portion of each rod or sha-ft entends into .the interior of the chamber, so that said rods or shafts may be Withdrawn or disconnected from their holding-down devices from Within the chamber.

When the chamber is positioned iby the means before described on the deck of a subemarine vessel, a manhole provided in the former will be in alignment or register with a manhole provided in the deck of the latter, suitable provision being made for inaking and maintaining watertight joints.

5 Therefore, should the vessel when submerged be unable to rise, the crew will enter lsaid chamber (in which there may be stored only gen, rockets, food, et cetera) from the submarine vessel, and, after etlecting Water- --3 tight closure of the manhole by means of a door or plate,"v`vill Withdraw `said rods or shafts from said exterior holdingdown de vices" by inea-ns of suitable tackle which will ensure simultaneous release ofthe rods or 5 shafts from the holding-down devices on v'the deck, so that said chamber `with the occupants will vbe Jfree to rise -to the `surface of the Water; i Suitable stops may be provided on said adjustable Arods or shafts yin-c`n"d r 'to limit and control the longitudinal movement of same through `the sides or walls Iof the chamber,'and the chamber apertures Wherethrough said rods or shafts pass Will be made Watertight by means .of suitably packed glands, or the like. A hermetically sealed belt, yor compartment, or compartments, may be provided Within or Without said chamber in order to enhance the `buoyancy thereof.

.A conning tower of appropriate construe tion may be 4releasably secured to asu-bmw rino vessel in the .manner hereinbefore .described. l

In the application ofmy invention `to ships generally, an appropriately constructed house, or like structure is provided on a deck of the vessel and detachably anchored thereto, in the manner before described, being releasable, if desired, from the inside of the buoyant structure, or by projection of `said rods or shafts inwardly from the outside of the structure.

Life-boats may also be detachably `secured in position in the manner described.

In ythe accompanying sheets of eiplana-` tory drawings, there are illustrated, by v`vvay of examples only, various modes of carrying my invention into effect.

In said dravvings F ig. l is a longitudinal section, and Fig. 2 a part sectional plan, of a submarine vessel provided With a lifesaving chamber embodying my invention.

Fig. 8 is a fragmentary section of Va chainber of modiiied construction.

Figs. 4l and 5 are elevations, taken at right angles to each other, illustrating the application of my .invention to the holding down of a ships life-boat.

Figs. 6 and 7 are views of steaniship and submarine vessel respectively, provided With ymy improvements.

In the several views? like characters of ref# e-rence denote like or equivalent parts Where ever they occur.

Referring first to Figs. l and 2, l

l designates a steel chamber in opposite Walls la' near the floor -lb whereof areprovided bearings .2 in which. are fslidably dis-A posed rods or shafts 3. The outer portienef nio each rod or shaft 3 is adapted to enter the eye 4 of a bridle, bracket, or other suitable holding-down device 5 which is secured to the deck 6 of a submarine vessel 7, whilst the inner end of the shaft 3 is pivotally connected at 8 to the lower end of a rod 9 which extends upwardly to and lis connected with a shaft 1() revolubly mounted in bearings 11 provided at the upper endof chamber 1. Connected to each shaft 10 near the wall 1c of chamber 1 is an end of a rod 12 to the inner ends of which rods are attached ends of a suitable flexible connection 13 which is led over a ring or eyelet 14 Vsecured to the wall 1c of` a the chamber and hangs downwardly as shown in Fig. 1. It will, therefore, be seen that by pulling said connection 13, with consequent operation of rods 12, shafts 10, and rods 9, said shafts 3 are simultaneously actuated, being moved inwardly, andwithdrawn from engagement with the eyes 4 of brackets 5. Rubber washers 15 backedby stop nuts 16 are provided on the shafts 3 so that watertight sealing of the chamber is eii'ected when "i the shafts are either in their projected or retracted positions.

A sunk portion 6a of deck 6 of the sub-` marine vessel 7 has a manhole 17 which may be closed by means of a hinged plate or cover 18 secured by swing bolts 19, awater-tight joint being effected by the packing ring 20. l Bolted to the upper face of said sunk portion 6a and surrounding the manhole 17 thereof, is a flanged ring 21 the inner face whereof is screw-threaded, and bolted tothe Hoor 1b of the chamber 1 is a bush or sleeve 22, kthe interior whereof is screw-threaded.

Screwed through said bush or sleeve 22 and engaging the screw-threaded ring 21 is tubular member23 to the upper flanged portion 23n whereof is pivotally connected a manhole cover 24 adapted to be secured by means of swing bolts 25.

26 denotes a water-tight joint-making packing ring located between the lower face of thev flange 23aL of the tubular member 23 and the ange 22a of the bush or sleeve 22; and 27 is a packing ring disposed between the manhole cover 24 and the upper face of the flange 23a of tubular member 23.

The pitch of the screw-threading is preferably such that less than a full turn of the tubular member 23 will ensure its release from the screw ring 21 secured to the sunk deck portion 6a ofthe submarine.

Should the submarine vessel become submerged and unable to rise to thel surface of the water, the manhole covers 18` and 24 are opened-as indicated in dotted lines Fig. 1 so that the members of the crew may pass from the submarine vessel 7 through the manhole 17 and tubular member 23, into the chamber 1. If then the manhole cover 24 be closed and secured in alwater-tight manner by swing boLts 25 and the tubular member,V

submarine vessel and rise to the surface of the water, when manhole cover 29 provided withV a Vwater-tight joint-making packingv ring 30, may be opened.

In the modification illustrated in Fig. 3 the chamber is composed of double walls having an air space 31 between same.

Referring to Figs. 4 and 5 of the drawings, there is shown a. life-boat 32 which is detachably held on the curved deck of the vessel by means of slidable shafts 3 portions of which extend into the boat and are'operated through rods 33 by means ofa pivotal handle 34 to which said rods are connected. In order to facilitate the launching of the boat, there is provided an apron-like member 35 pivotally connected to the ship at 36. Vhen the life-boat is to be launched, apron 35 is lowered by means of ropes 37 to the position shown in full lines Fig. 5, and the boat, which has slots 32 in the keel 39-,wh`erein projecting members 40 of the apron 35 engage-is slid down `the apron, being controlled by the tackle 41.

It will be seen that lshould the vessel take a list in the direction of the arrow (Fig. 5) the launching of the boat will not .be interfered with or prevented. y

In Fig. 6 the chamber,-adapted as a deck house-together with the life-boats 32 of the kind described with reference to Figs. 4 and 5, are shown fitted on the deck of a steamship 42.

In Fig. 7 the chamber is fitted on the deck 6 of the submarine vessel 7 What I claim as my invention and desire to secure by Letters Patent is 1. In safety structures for ships, submarines and the like, wherein a buoyant carrier may receive and transport human life from the vessel when submerged, and wherein the buoyant carrier is normally mounted on the deck of thev vessel, a buoyant carrier having its opposite side walls each carrying a rod-like member movable endwise within definite limits and adapted to prevent leakage of water into the carrier when in either extreme of its movement; means within the container for shifting said rod-like members concurrently,` said means including rockshafts and levers forming a unit individual to the respective rod-like members, and a connection for said units to provide concurrent movement of the units; individual members carried by the deck to receive the outer ends of the rod-like members when the latter are projected; and hatchway means operativelyjand detachably connecting they 13e/reis carrier and Vessel approximately central of the bottom of the carrier, said latter means including a tubular member permanently carried by the carrier and supporting the carrier hatchway cover, and a ring-member Carried by the Vessel, With said members complement-ally threaded for quick detachment, said tubular member forming the passageway between vessel and carrier, with the vessel having a hatchWay cover for the Vessel end of' the tubular member.

2. A structure as in claim 1 characterized in that the Vessel has a depressed deck zone to receive the ring member of the hatchWay means, the bottom of the carrier being substantially free from projections other than the tubular melnben, vwhereby the bottom Wall of the carrier Will normally rest upon the deck of the vessel.

In Witness whereof I have signed this specification.
