((21. 114-435) The present invention relates to new and useful improvements in ships for use particularly in time of war, and has for its primary object to provide a vessel of this character comprising unique means for carrying and expeditiously and safely launching a plurality of small but swift and powerful protective or life boats.

Another very important object of the invention is to provide a ship of the aforementioned character which embodies novel means for recovering the boats. 4

Other objects of the invention are to provide a ship of the aforementioned character which will.

be comparatively simple in construction, highly eflicient in operation, seaworthy, and which may be produced at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of thefollowing specification, taken in connection with the accompanying drawings wherein like characters of refer-' ence designate corresponding parts throughout the several views, and wherein:

Figure l is a view in side elevation of a ship constructed in accordance with the present invention.

Figure 2 is a fragmentary view in horizontal section, taken substantially on the line 2-2 of Figure 1.

Figure .3 is a fragmentary view in vertical 1ongitudinal section, taken substantially on the line 3-3 of Figure 2.

Figure 4 is a cross sectional view, taken substantially on the line 4-4 of Figure 3.

Figure 5 is a cross sectional view through the crane.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a shipJ including a hull 2. Of course, the hull 2 may be of any suitable dimensions and material. The sides 01 the hull 2 are provided, in the bow portion of said hull, with series of openings 3.

Within the hull 2, adjacent the openings 3, is a substantially anticlinal deck 4. Fuel tanks 5 are provided below the deck 4. Below the fuel tanks 5, ballast tanks or chambers Gare provided.

Standards I rise from the axis portion of the deck .4. Longitudinal shafts 8 are fixed on. the standards I. Transversely extending platforms 9 are mounted, at an intermediate point, for rock-' ing movement in a vertical plane on the shafts 8. Toward this end, the platforms 9 include depending bearings III which are journaled on the shafts on their sterns a plurality of depth bombs, as at 8. Opposed, coaxial disks II are fixed on the shafts 8 and the plaforms 9. The pairs of disks ll have formed therein openings l2 for registry with each other, Pins l3 areinsertible selectively in the registering openings I2 for-releasably' securing the platforms 9 against rocking or swinging movement on theshafts 8.

The platforms 9 are adapted to support and launch boats l4. Toward this end, the platforms 9 further include rollers l5 and, opposed guides 30 adjacent the ends of said rollers. Cradles ,3l,

for the boats 14, travel on the rollers IS in the guides 30. Chains l6 releasably connect the boats M to the platforms 9. Platform H n the deck 4 facilitate getting into and out of the boats l4; I

Mounted longitudinally in the side portions of the hull 2, above the boats 54 onthe platforms 9, is a pair of tracks 68 in the form of I beams. A transverse crane I9 is operable on the tracks Hi. The crane I9 comprises an inverted channel iron 20 having fixed on its ends carriages 2|, said carriages including rollers 22 which travel on the tracks l8. Fixed on the side portions of the channel, iron 20 and depending therefrom in parallelism therewith is a pair of opposed channel guide members 23 having rollers 24 mounted in their lower portions. A boom 25 in the form of an I beam is operable on the rollers 24 between the guides 23. A carriage 26 is operable 0n the boom 25. Coacting stops 21 on the channel iron 20 and the boom 25 limit the travel of the latter. Stops 28 for a similar purpose are provided on the boom 25 for the carriage 26. Rollers 32 on the boom 25, outwardly of the stops 21 thereon, travel beneath the channel member 20 for preventing said boom from binding thereon.

It is thought that the operation of the invention will be readily apparent from a consideration of the'foregoing. Briefly, to launch the boats M, the chains l6 are released and the pins l3 are withdrawn. Thus, the platforms may be rocked on the shafts 8 to an inclined position for launching the boats through either of the openings 3, the platforms 3| traveling by gravity on the rollers l5. Stops 33 on the guides 30 bring the cradles 3| to a sudden stop and the boats I'4 slide by momentum and gravity from said cradles into the water.

In the embodiment shown, the boats l4 are ofthe protective or combat type. These boats are of any suitable construction, and they may carry 29. These boats mayalso include any suitable arrangement of air chanrbers for righting them jected laterally throughthe desired openin'g I over the water, as suggested in broken lines in Figure 4 of the drawings. The boats ll arethen lifted out of the water by means including a suitable block and tackle arrangement suspendedfrom. the carriage 2|. The crane I! may be manually or power operated. If desired, the openings 3 maybe closed in any suitable manner. The construction and arrangement, it will be observed, is such that the boats may be launched and recovered; on either side of the hull 2.

It is believed that the many advantages of a ship constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the vessel is as illustrated and described, it is to be understood that changes inthe details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

assay/s What is claimed is:

A ship comprising a hull having transversely aligned openings in its sides, a substantially anticlinal deck in the hull between the openings, standards rising from the longitudinal axis of the deck, a shaft fixed on the standards and paralleling said longitudinal axis of the deck, a platform pivotally mounted, at an intermediate point, for rocking movement in opposite directions and in a vertical plane on theshaft, said platform including rollers and a pair of guides, a cradle, for supporting a boat and for launching said boat through either of the openings, operable on the rollers in the guides, and means for releasably.

securing the platform against rocking movement on the shaft, said means including opposed, coaxial disks flxed on the platform and the shaft. said disks having openings therein for registry with each other, and a pin insertible in the registering openings.
