T0 all 'whom 'it may concern:

Be it known that I, JOSEPH BARRAJA- FRAUENFELDER, a citizen of the United States, residing at Bridgeport, in the county Y of Fairfield and State of Connecticut, have `a disabled sunken submarine boat, and to provide means for attaching a hoisting cable to the disabled craft without the services of divers, so that the disabled craft may be either raised to the surface or hauled over the water-bed intol shallow water where the rescue of the crew and salvage operations may be more conveniently and expeditiously carried out.

'The invention consists in providing a marker-buoy which is firmly locked in a cylindrical receptacle built upon or secured to the boat, said marker-buoy having messenger-lines detachably connected thereto which are coiled in recesses or pockets formed in the receptacle and held in place bythe lmarker-buoy, the marker-buoy being seated water-tight upon the receptacle to prevent water from entering said recesses or pockets in the event of the deck of the boat being washed by heavy seas or when ther boat is submerged under normal conditions, whereby the messenger-line is ke t dry and prevented from being damaged y the water.

The invention further consists in certain peculiar features of construction, combination, and arrangement of parts'as will be hereinafter fully described and then claimed.

In the drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a diagrammatic view illustrating the application of the invention. Fig. 2 is a vertical longitudinal section of a portion of the hull of a submarine boat and the superstructure arranged thereon, and illustrating the marker-buoy in position on its receptacle. Fig. 3 is a vertical longitudinal sectlon of the receptacle showing the marker-buoy in elevation and detached from the receptacle. Fig. 4 is a side elevation of the anchor-bolt used in connection with the invention for attaching a hoisting cable to the boat. Fig. 5 is an inverted plan view of the markerbuoy. Fig. 6 is a horizontal section of the receptacle drawn on the line a-a of Fig. 3. 4`ig. 7 is a vertical transverse section drawn on the line b-b of Fig. 3, illustrating the anchor-bolt in locked position in the receptacle.

1 designates a submarine boat having a superstructure 2 built thereon in which, preferably adjacent to the ends of the boat are wells 3, the walls of the wells being fiared outwardly at their upper ends as atl 4. Within each well is a cylindrical receptacle 5 for the marker-buoy 6 and as the receptacles and marker-buoys are exactly allke in construction only one will be described. Each receptacle is cylindrical in cross-section and formed at its lower end with a flange 7 which is riveted or otherwise rigidly connected to the hull plating 8 of the boat, and intermediate its ends is provided with a horizontal partition 9 from which extends a tubular sleeve 10, having its upper end flush with the top of the wall of the receptacle providing an annular recess 11 and a central socket 12, which is of larger diameter intermediate its'upper and lower ends tol provide a shoulder 12 designed to be engaged by spring actuated pawls carried by anfJanchor-bolt as will be ereinafter more fully described.- Within the lower end of the socket 12 is a short sleeve 13 providing an annular recess or pocket 14 in the lower end of the socket 12 and in which is wound one section 15 of a messenger-line carried by the marker-buoy 6, the opposite end, or section 16 of the messenger-line being wound around the sleeve 10 in the lower end of the annular recess 11. Extending from the lower side of the transverse partition 9 are ears 17 in which is journaled a sheave 18, around which the messenger-line operates. As shown in Figs. 2 and' 3 one end of the messenger line extends through an opening 19 in the partition 9 which leads into the re cess 11, while the other end passes up through the short sleeve 13, said sleeve being provided with a. slot 20, whereby the- Patented June s, 1915. l

messenger-line may be coiled in the Ypocket v 14 without extending the line entirely Y through the sleeve as illustrated in Fig. 2.

21 designates a guard vband arranged partly around the sheave to lprevent the messenger-line from jumping the sheave as will be readily understood.

The marker-buoy 6 is hollow and ma be a metal casting or constructed of s eet metal as desired, and is formed with ahead 22 having a convex top and tapering side Walls which are inclined inwardly from their upper toward their lower "ends, the .angle of the walls corresponding to the angle of the upper end 4 of the well 3, so

that it will snugly twithin the well when locked in position upon the receptacle.

. annular recess 11, and a hollow central section 24 which is designed lto snugly fit the upper end of the socket 12, the said sleeve 23 and hollow section 24 being of such a length that when in position in the receptacle the lower ends thereof will rest upon the coiled messenger-line as shown in Fig..2, to hold the coils in position and prevent them from being tangled. The end of the section 15 of the messenger-line is connected to an eye-bolt held in a recess 25 formed in the lower end'oi` the said hollow section 24, and the end of the section 16 of said messenger-line is connected to an eyebolt held in a recess 26 formed in the lower fend of the sleeve'23. The lower side of the head 22 is formed with annular recesses or sockets to receive. packing rings 2'( of suitable -material which engage the upper ends of the outer wall of the receptacle 5 and the top of the sleeve 10, respectively.

In order to securely lock the mar er-buoy in position upon'the receptacle and to press the packing* rings firmly into engagement with the up er ends of the wall of the receptacle an the sleeve to provide watertight joints, I provide the following arrangement :-Pivoted in ears 28`- extending outwardly from the flared end 4 of the well 3, below the deck 2 of` the superstructure, are pawls 29 having theirfree ends operating through slots 30 formed in the section have their inner ends threaded. Upon the.

threaded ends of the bolts operate hand wheels 35, the hubs of which bear against brackets 37 and the inner ends of the 'stufing boxes 34, so that as the wheels are rotated Athe rods 33 and their connections will be raised and lowered to thus operate the pawls 29.Y By this construction it will be under'- vstood, that, when the wheels are rotated in mitting its removal when the boat is on the surface of the water and also permitting it to be floated to the surface when the .boat is submerged. From the lower side of the head 22 of the The invention so far as described follows vbuoys proposed for use in connection with submarine boats, and it will be understood, that should the buoy be released when the boat is submerged it will rise to and float upon the surface, the

lengths

15 and 16 of the messenger-line'being automaticalluncoiled as the buoy rises to the surface. owever, in connection with the invention as described I employ means for attaching hoisting cables to the4 receptacle, to lift the boat to the surface or to drag it over the water-bed #into shallow Waters where salvage operations may be conveniently carried on. -As stated, the socket 12 is formed with a shoulder 12 designed to be engaged by spring actuated pawls carried at the lower end of an anchor-bolt carried by a Vbuoys are first released and allowed to float to the surface and when icked up by a surface craft the end of t e section 15 of theline is detached from the buoy and connected to the yanchor-bolt, preferably as shown in Fig. '7, th'e end ofthe length 16 of` the line is then detached andas the hoistingcable is lowered the end 16 of the line is drawn upwardly to thus guide and pull the anchor-bolt into the socket-12, it being un` derstood that when the lower end of the anchor-bolt enters the said' socket 12`the pawls 42 will be pushed inwardly into their Y recesses against the tension of their springs until the upper ends of said pawls pass the shoulder 12 of the sleeve 10 when the springs will force them ,l outwardly and under the shoulder 12 thus locking the anchor-bolt to the receptacle, after which, by suitable hoisting apparatus, the sunken craft is either drawn to the surface of the Water or hauled over the water-bed into shallow Waters as previously described.

It will thus be seen that the invention is exceedingly simple in construction and that a hoisting-line lor lines may be readily connected to a disabled sunken submarine boat without the employment of divers, irrespective of the depth of the water in which the boat may have been sunk, and will be found particularly advantageous in recovering a disabled craft when it has been sunk be ond the working depth of divers. It wil, of course, be understood, that while not shown, suitable telephone Wires may be carried by the marker-buoy whereby communication between a surface boat and the sunken boat may be established. As this feature forms no part of the present invention I have not thought it necessary to describe it in detail nor to illustrate it.
