SUBMARINE-DESTROYER.

Appncatioii To all whom 'it may concern r Be it known that I, GEORGE H. GEORGELis, a citizen of the United States, and aresl- .dent of Fort Screven, in the county of Chatham and State of Georgia, have invented a certain new and useful Improvement in `Submarine-Destroyers, of which the following is a specification.

The present invention relates to ships, and more particularly to those of the submarine type. i

The object of the present invention is to provide a submarine water craft of a construction adapted for use as a destroyer of submarine craft; a device capable of attaining relatively high speed in travel, particularly when submerged; a craft which relatively simple and strong in construction; and a craft which may be driven at a Vhigh rate of travel with a minimum speed of op eration of its parts.

Another object of the present invention is to provide a submarine craft having an exterior hull or shell which is continuous and adapted to rotate about the car or body of the craft, and which is driven for iin-pelling the craft through the water at a high rate of speed by exterior spiral lins upon they hull; and which is provided `with means for holding the hull in various positions of rotation to enable the retention of any puncture-d or injured port-ion of the hull at the that tthe craft inlayv be raised to the sil1facei"le\'el ofvthe water and propelled b v other means: provided to a place of safety and repair.

'.l`he invention also embodies the provision of a connecting shaft or axle which pivotall)Y connects the hull to the car or body of the craft and which is providcrfl at its forward end with an impact point of hard steel o'r -the like resiliently connected to the shaft for absorbing shock incident to the striking of the point against. other sulnnarinesor other obstacles. 'y

The above, and various other objects and advantages of this invention'will be in part described and in part understood from the followingr detailed description of the present.

preferred embodiment of this invention, the, saine being illustrated in thtaccompanying drawings. wherein:

Referring to the drawing by numerals, 10

designa-tes the hull' or shell of the craft of preferably oblong contour 'with `tapering ends adapted to pass freely through a body of water. The hull 10 is' provided with a number of spiral ribs or tins 11 upon-'its exterior surface which extend from end to end of the hull. Arranged axially within the hull is a hollow tube or shaft 12 mounted for rotation at its opposite ends in the front and rear ends of the hull and provided at its forward end with a closure plug 13 within the outer end of which is'slidably mountfas ed an impact point 11, the latter being cushioned ,within the plug 13 by a springl.

Impact Aagainst the point 14 is absorbedtto a considerable extent through the spring` 1 5 so that injury to the shaft 12 and hulllOfand the parts carried thereby is practically eliminated.

Suspended from the hollow shaft v12 by straps 16 is a body part or car 17 having an upper decl; or platform 18, lying substantially within the horizontal plane of t-hc longitudinal axis of the shaft 12. This body or ear 17 ma)v be. divided into a plurality of. compartments as showii'in Fig. 3, and is adapted to contain stores and the like-for use in handling and manipulating the craft.

fl'ength of the craft, means and extending annularly about the inner sur- Aface of the hull 10 and providing an linder-A Ilying slot or-way to receive rollers 20 car- .ried by brackets 21 upon the bottom and sides of .the car 1,7. These rollers 20 are mounted' upon T.shanks the branches of which engagethe Vrollers and project beneath thefrail's 19. `The ,rollers 20 travel in 'the .annular ways as the hull is lrotated-and prevent the body- 17 from shifting longitudinally upon or with the shaft 12.

A" periscope 22, or'the like may be mount- -ed uponithe plug 13 and is provided with a sight tube 23 extending through the plug to the interior of the hull. The hull may thxus rotate about the shaft and plug without disturbing'the position of the periscope. As shown in Fig. 4, the hull 10 is preferably mounted directly upon a plurality .of rollers 24 constituting andthe shaft 12.. l

The rear end of the hull has an inwardly extending drum 25 surrounding the rear end of the shaft and forming, practically, a continuation of the hull, a packing gland 264 being lforced into av suitable openingin the drum 25 and surrounding the shaft to pack the same in the hull. A brake band 27 sur'- rounds the drum 25 and is operable, through a link 28 by a'hand lever 29 supported upon ythe platform 18 of the body. vThe brake may be manipulated to hold the hull in any desired positlon of rotation.A

For the purpose of turning the hull 10 about the body, a suitable motor or engine 30 may be employed, the engine being mounted upon the deck 18 and having a crank shaft 31 projecting forwardly from the engine and provided with a worm 32. A worm wheel 33 meshes with the wormand is carried on a shaft 34 extending transversely within the hull` and coupled, by

ions 37 meshing' with an internal rack or gear wheel .38. secured to the inner surface of the hull`10. The engine 30 has its shaft 31 rojecting'rearwardlyand connected by sha'liting and universal Joints, such as indicated at 39, to a propeller 40 of the screw type for driving the craft when the hull is held from turning. Sui-tableclutches or the like may be interposed between the Iengine and the hull, and the engine and the pro? peller.

At a suitable point upon the car or body 17 is a tiller wheel 41 connected by shafting 42 and bevel lgears to a. rudder 43 hinged upon the rear end of the hull and adaptedv to be used for controlling the movements of the craft in the water.

bearings between they hullbevel pinions 35 to counter shafts 36 provided with driving pinl A' The car'l'? isf'provided-'witlr one orimore rubber or the like adapted strips 47 ofhar to seal the ds in the hull when closed. The door's46;l l shown in Fig. 8, are formed 'to bind in tlieiull when the doors are swung outward, and aisoby centrifugal force incident to the'rotation of the hull. -Thze hull is providedat suitable `points with bracing rings y48 to strengthen-)she hull andwhich preferably are alinular'in'forln and secured to the inner Wall of the hul-l., The hull may be provided at one or more sides'with' pairs of spaced sockets -49 to receive staffs 50 adapted to support a wireless antennae .51 when the craft is lying adjacent the surface vlevelfof the water. I Searchlights 52 are detachabl mounted upon the exterior of the hull at li whichy may be of 4the construction shown in Fig. 8. Wires 54 lead` from a battery or exciter 55 carried uplon the body 17 for su lplyl'ng currenttot drawn from the hull and deposited `in the body 17, andthe gun 41 is lowered to the body 17 prior to ysubmerging'and to admit free rotation of the hull about the body? vIt-is thought that the operation of the craft will be readily understood from the above, for when the detachable parts are taken within the body, the latter may 4be submerged by any of the well known means, and the brake 27 released set in motion for turning the hull.

It is' of course understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention withoutdeparting from the .spirit thereof, such changes and modifications being restricted the following claims.

l/Vhat is claimed is:

1.
