Application filed December 7, 1912. Serial No. 735,404.

l] all ywiz-m tmf/.y concern Be it known that l, AUGUST l-IAAs, a resident of Grapeville, in the county of Westmoreland and State of Pennsylvania, have invented certain new and.useful Improvements in Combined Life-Boats and Marine Safes, of which the following is a 4specification. One object'of this invention is to provide an'emergency life and cargo boat for ships, with means for readily launching the boat clear of the ship whenever the latter is in danger, the emergency boat being of a size to accommodate passengers and crew, also the more valuable cargo.

' A further purpose is to soconstruct the emergency boat that when released from its berth in the ship it automatically launches itself andv floats on an even keel regardless of its increasing depthmtoward its stern.

Still a further purpose is to provide improved means' for releasingthe emergency 'boat for launching after the passengers and crew have been assembled therein.

Still a further purpose is to so construct the emergency boat as to make it seaworthy, in the preferred construction a double keel being provided, the latter supporting the boat in its berth and facilitating its launching.

.In the accompanying drawings, Fio'ure 1 is a side elevation of a ship equipped with the improvedemergency boat. Fig. 2 is an elevation ofthe rear portion .of the ship partly broken away to illustrate the emergency boat berth, the boat being shown in dotted lines, and Fig. 8 is an elevation of the emergency boat after it has been launched from the main ship. Fig. e is a top plan of the rearportion of the ship and emergency boat. Eig. 5 is a rear elevation.

Referring to the drawings, Q designates the hull cfa ship, and 3 is a cavity or depression in the rear end thereof which is open through the stern, the bottom of the depression sloping rearwardly and downwardly to its open end, with 'the inclined tracks or guideways 5 at opposite sides thereof, as shown. Cavity 3 iorms a berth for' an emergency boat 6 which is releasably held therein, being provided on oppositeV sides f itsbottom with .the longitudinal runners 2l` which support theboat on. the gnideways The bow. 6 of boat t3 is adapt-eel to enter an odset 3 in berth 3, and mounted on how 6 is the vertically movable bolt 8 which is adapted at its lower end to engage catch 9 secured to the deck of hull 2. Bolt 8 is operated by lever lO mounted on bow 6 of the emergency boat, the arrangement being such that when the rear end of lever 10 is depressed its front end is raised and releases bolt 8 from catch 9, thereby freeing the emergency boat so that it may launch itself by gravity from berth 3. A locking pin ll must be removed before the lever can be operated.

A characteristic of the invention is the form of emergency boat 6, the latter being deepest at its stern and decreasing in depth toward its bow, the inclination of the boat bottom being preferably complementary with the inclined bott-om of the berth and at such' an angle as to maintain the decks of the emergency boat substantially horizontal. The emergency boat is thus adapted for varions uses while in position in berth 8, the decks thereof being available for saloon purposes, cargo, etc. ln order that boat 6 may loat with its decks level orlsubstantially so, its deeper stern portion should be loaded more heavily facilitated by the form of the boat, the

than the bow. This is y deeper rear end thereof providing space for relatively short decks l2 which may be utilized for the heavier machinery and for fuel. Also, one or more of these lower decks may be used for valuable cargo which is thus safe-guarded and at the same time serves as a ballast for the boat. Runners 7 constitute a double keel forthe emergency boat which insures its stability when. afloat. lt is designed to have boat fully equipped with propelling and steering machinery, etc., so that it may be navigated and be fully self sustaining in an open sea,i

lt is vthe design'to have boat 6 of sufficient site to provide a refuge for all of the pas.- sengers and Vcrew in the event-that the ship must be abandoned, the more valuable cargo being stored therein and also saved from disaster. As beforel indicated, the space within the emergency boat may be variously utilized for saloon and other purposes, and as the boat is readily accessible from the main ship passengers and crew may pass to and from the same without inconvenience. The position l.ofthe emergency boat at the stern of the ship is such that it is fully protected excepting at its rear end where there is'practically no danger of injury. it either side of the berth the hulll'of the ship .is of sufficient width to fully protect the emergency boat from side collisions, and with the latter self-launching in the event of imminent danger it is only necessary to assemble the passengers and crew thereon and release the boat by retracting bolt 8 when it will slide into the water clear of the ship. ln

` v the event that the rear portion of the ship is injured by collision or otherwisel in such manner as to prevent or interfere with the launching of the emergencyT boat, the latter will loat clear ot the ship if the latter sinks, it being characteristic of the invention that there is nothing to impede upward movement of the boat in berth 3 and its passage from the top of the latter. If in an emergency the boat is floated in this way the clearance between the boat sides and the berth walls, also the space at the bottom ot the boat between runners 7, admit water in sufficient volume to quickly float the boat and prevent it from being drawn under by the suction caused by the sinking ship.

I claim zl. The combination of a ship formed with a berth open through a wallI thereof, the berth provided with slideways sloping upwardly from its outer end to its innerl end, an emergency boat having` its bottom sloped from end to end complementary with the sloping slideways and adapted to rest and slide on the latter, the emergency boat having decks that are substantially level when the boat is in position in said berth and also which are substantially level when the emergency boat is a'lioat and separated from the ship.

2. The combination of a ship tormedfwith a berth open through the stern thereof, the berth provided with downwardly and outwardly sloping slideways, an emergency boat, downwardly projecting runners arranged longitudinally of said boat and slidable on the slideways, and means for detaclr ably securing said boat within the berth.

8. The combination of a ship formed with a berth open at one end through a wall of the ship, downwardly and outwardly inclined slideways in the berth, an emergency boat having its greatest depth at its stern end and decreasingin depth toward its bow, runners extending longitudinally of said boat and sloping downwardly from its bow to its stern with the runners supporting the boat on said slideways, and means for removably confining the boat within said berth.

4f. The combination of a ship formed with a berth open at one end through a wall of' the ship, downwardly and outwardly inclined slideways in the berth, an emergency boat having its greatest dept-lr at its stern and decreasing in depth toward its bow, run- ,ners extending longitudinally of the boat at oppositev sides of the bottom thereof with the runners inclined downwardly from the bow to the stern and supporting the boat within the berth of said slideways, and means for removably confining the boat within the berth. y

5. The combination ot 'a ship formed with a berth open through a wall ot the ship, a sellaunchin emergency boat within the berth, a vertically movable bolt carried by said boat with its lower end adapted to engage a socket in the ship, and a lever fulcrumed on the emergency boat andoperatively connected to said bolt with the lever accessible from the emergency boat :tor releasing the latter. i
